Injuries and/or lesions are often described by
their location in the brain in combination with
simple Latin prefixes (e.g. sub, pre, intra)

3
Basic functions of the brain
Often in brain injuries, more than one area of
the brain is affected. Damage can also be caused
by secondary complications such as swelling.

Back to basics Cancer Cancer is a term used
for diseases in which abnormal cells divide
without control and are able to invade other
tissues. Cancer cells can spread to other parts
of the body through the blood and lymph systems.
(National CA Institute (NCI) at www.cancer.gov)
  • The five subcategories of cancer are
  • 1)       Carcinoma - cancer that begins in the
    skin or in tissues that line or cover internal
    organs.
  • 2)       Sarcoma - cancer that begins in bone,
    cartilage, fat, muscle, blood vessels, or other
    connective or supportive tissue.
  • 3)       Leukemia - cancer that starts in
    blood-forming tissue such as the bone marrow and
    causes large numbers of abnormal blood cells to
    be produced and enter the blood.
  • 4)       Lymphoma and myeloma - cancers that
    begin in the cells of the immune system
  • 5)       Central nervous system cancers - cancers
    that begin in the tissues of the brain and spinal
    cord. (NCI)
  • All cancer cells can be placed into one of these
    subcategories.

7
Stats and potential causes
  • Potential causes of cancer
  • 1) Chemical or toxic compound exposures
    Benzene, asbestos, nickel, cadmium, vinyl
    chloride, benzidine, tobacco or cigarette smoke
    (contains at least 66 known potential
    carcinogenic chemicals and toxins), and aflatoxin
  • 2) Ionizing radiation Uranium, radon,
    ultraviolet rays from sunlight, radiation from
    alpha, beta, gamma, and X-ray-emitting sources
    (the primary concern in Japan at this time)
  • 3) Pathogens Human papillomavirus (HPV), EBV or
    Epstein-Barr virus, hepatitis viruses B and C,
    Kaposi's sarcoma-associated herpes virus (KSHV),
    other bacteria are being researched as possible
    agents
  • 4)       Genetics/family history (ACS.com)
  • Statistics
  • More than 200 types of cancers in existence
  • There are more than 120 types of PRIMARY brain
    tumors (NCI, 2011)
  • More than 80 of patients in clinical trials
    experienced speech, language and/or cognitive
    decline for up to a year post treatment
    (American Cancer Society at www.cancer.org, 2011)
  • Up to 40 of patients with high grade gliomas are
    reaching a lifespan of up to 5 yrs post dx.
    (American Brain Tumor Association at
    www.abta.org, 2011)
  • 40 of patients will be eligible for
    participation in a clinical trial at some point
    during their treatment (City of Hope at
    www.cityofhope.org)

Tumor An abnormal lesion and/or group of cells
that serves no purpose. Types of
tumors 1)       Primary Generally begin in the
CNS and do not metastasize 2)       Secondary
Start in one area of the body and metastasize to
somewhere else. Most common cancers and where
they like to migrate
10
Signs and Symptoms
  • Chronic headaches
  • Vision changes/loss
  • Frequent dizziness
  • Depression/mood and personality changes
  • Hearing reduction/loss
  • Hormonal changes
  • Changes in sensation (numbness, tingling)
  • Fatigue
  • Hormonal changes
  • Seizures
  • Movement changes and/or loss
  • Sensory changes and/or loss
  • Associated with the location of the tumor, its
    size, and cerebral areas impacted.

11
Diagnostics listed in order of occurrence during
the continuum of care
Step one CT scan. Pros 1) Can easily
diagnosis large structures in the brain. 2)
Cheaper than most other diagnostics 3) Faster
than most other tests (usually 30-60
minutes) Cons 1) Pictures are still life, 2)
Cant detect changes in vasculature. 3) Images
are B W, 4) Not sensitive to subtle changes in
the brain
Step Two MRI Pros 1) Can easily detect
abnormalities in blood flow,, 2) More efficient
at finding tricky margins/edges of tumors. Cons
1) Pictures are still-life, 2) More expensive
for hospitals and patients, 3) time consuming (90
min. ), 4) more restrictive (e.g. cannot use on
patients with some PO, pacemakers, shunts, vagal
nerve stimulators, etc.)
12

Step Three Function MRI (fMRI) This image
displays the cortical surface in transparent
gray. Within the brain are shown fMRI activations
in teal, arteries in red, tumor in bright green,
and white matter fiber tracking in yellow
(MIT.edu)
Pros 1) Shows vacularity VERY clearly, 2)
shows not only anatomy, but also shows MOVEMENT
AND FUNCTION, 3) Can reveal feeder vessels and
where other cancerous material CAN spread. Cons
1) VERY expensive, 2) VERY long (1-2 hours), 3)
requires specialty equipment usually housed at
specialty hospitals, 4) Can be rebutted by
insurance companies (argue that a still-life MRI
may suffice), 5) Does NOT reveal what type of
cancer is present.
13
PET Scan (Positron Emission Tomography) 1)
NPO x 6-8 hours prior 2) a tracer is injected
into the bloodstream or breathed in as a gas 3)
The patient waits about an hour for uptake of
the tracer 4) The imaging study is performed.
Sometimes patients are asked to read names or
letters if memory/language is being tested. Test
time requires between 1-2 hours. 5) Uses the
uptake of glocose to produce an image. 6)
Usually used well into the cancer
journey More active areas show up in warmer
colors (red/yellow/orange). If the brain is
burning glucose more quickly than normal,
high/abnormal activity is suspected.

Pros 1) Can identify hard-to-find tumor
margins 2) Can help determine if a tumor is
benign or malignant 3) Helps determine if
chemotherapy is/will be effective (by examining
the brains ability to absorb /uptake foreign
material) 4) Can help discern if multiple cancer
types are present Cons 1) Some patients have
reactions to the tracer itself, 2) results can be
skewed with patients who are diabetic, or on
corticosteroids and/or insulin.
14
The WHO Tumor grading system
  • GX Grade cannot be assessed (Undetermined
    grade)
  • G1 Well-differentiated (Low grade)
  • G2 Moderately differentiated (Intermediate
    grade)
  • G3 Poorly differentiated (High grade)
  • G4 Undifferentiated (High grade)
  • Grading is based on irregularity of cells as
    compared to normal cells,
  • vascularity, and likelihood of spreading.
  • This scale is ONLY used for primary
    tumors.
  • Secondary tumors and/or tumors from
    other types of cancers are graded using the
    Gleason scale ranging from 2-10 (NCI, 2011)
  • Note Tumor grade should NOT be confused with
    the stage of a cancer. Cancer stage refers to the
    extent or severity of the cancer, based on
    factors such as the location of the primary
    tumor, tumor size, number of tumors, and lymph
    node involvement (NCI)

15
Examples of what you may see in an imaging study
or oncology report
  • Grade II frontal glioma mildly/moderately
    vascular (usually operable) tumor of the glial
    cells in the frontal lobe
  • Grade IV frontopareitel glioblastoma highly
    vascular (often inoperable or able to be only
    partially resected), highly malignant , rapidly
    growing tumor of the glial cells.
  • Grade III left parietal astrocytoma
    moderate/highly vascular malignant tumor
    involving the astrocytes in the glial cells

16
The Underappreciated glial cell
  • Types and Functions of Glia
  • Astrocyte (Astroglia) Star-shaped cells that
    provide physical and nutritional support for
    neurons 1) clean up brain "debris" 2) transport
    nutrients to neurons 3) hold neurons in place
    4) digest parts of dead neurons 5) regulate
    content of extracellular space
  • Microglia Like astrocytes, microglia digest
    parts of dead neurons.
  • Oligodendroglia Provide the insulation (myelin)
    to neurons in the central nervous system.
  • Satellite Cells Physical support to neurons in
    the peripheral nervous system.
  • Schwann Cells Provide the insulation (myelin) to
    neurons in the peripheral nervous system.
  • Note There are an estimated 10-50x more glial
    cells in the brain as compaired to the number of
    neurons. (Neuroscience for kids)

  • Abundant in the hippocampus and the cortex
  • Most cells in the brain are either neurons or
    glia
  • Neurons can adapt (neuroplasticity) glia
    historically thought to be unable (though new
    research is suggesting it CAN!)
  • Glia regulate which messages are sent THROUGH the
    neurons, and WHEN
  • Remarkable research in mice (Scientific American,
    2013)
  • Q Why is this important?
  • A Because the most common types of PRIMARY
    MALIGNENT tumors originate in these cells! They
    are called gliomas.

19
This picture illustrates the the relationship
between astrocytes and blood vessels. The dark
'star-like' figures are the astrocytes.
Astrocytes provide nourishment to neurons by 1)
receiving glucose from capillaries 2) breaking
the glucose down into lactate (the chemical
produced during the first step of glucose
metabolism) 3) releasing the lactate into the
extra cellular fluid surrounding the neurons. 


http//blustein.tripod.com The uptake of
glucose is a critical function for brain cells,
which is why PET scans are so effective in
identifying types of cancers, effectiveness of
treatment and the often hard-to-see borders of
malignancy.
20
  • Whats in a name?
  • Remember tumors are named using the following
    criteria
  • Site of lesion
  • Vascularity (blood vessels that are feeding it)
  • Potential to infect healthy tissue
  • Type of cancer cells the tumor contains AND
    whether or not there are more than one TYPE of
    cancer cells in the mass.

21
Case in point
  • You work in outpatient therapy. Your team
    receives a referral for an evaluation of a
    40-something woman who has recently been
    diagnosed with a L temporal meningioma (labeled
    as grade II). She has mild word finding
    difficulties and complains of STM loss. She
    started radiation three weeks ago. You see her
    for 6/8 visits, but she is unable to complete
    her outpatient therapy due to fatigue (she cant
    handle tx while doing radiation).
  • 2) Eight months later, the same woman appears
    on your inpatient rehab floor s/p craniotomy due
    to a L frontotemporal astrocytoma (stage
    unspecified). Her neurosurgeon writes in his
    report it is a gross/total resection of the
    tumor. She presents with markedly increased word
    finding problems, visual spatial deficits and R
    hemi. She is now very disinhibited, aphasic and
    cusses a lot. She stays on rehab for 3 weeks,
    then is discharged to a local day treatment
    program.
  • 3) Another year passes, and the same woman
    is admitted a second time to your rehab unit, now
    s/p a bifrontal craniotomy s/p diagnosis of a
    glioblastoma multiforme. Her aphasia is worse,
    initiation is now very poor, and she has
    significant problems with the oral phase of
    swallowing (she just chews and chews and
    chews.). She is also a new diabetic.

22
Huh? What the heck happened?!
  • Doctors tried to treat the tumor. It
    probably didnt work as well as they had hoped or
    the patient couldnt tolerate treatment.
  • She did NOT grow another tumor (though this can
  • happen in rare cases)
  • Rather, as it grew, the tumor changed
    characteristics/morphed into something
    different. It also infiltrated another area of
    the brain.
  • RememberThose characteristics that change are
    vascularity, infiltration of healthy tissues, and
    complexity and/or number of different types of
    cancer cells.
  • Therefore The NAME of the mass changes as the
    characteristics change.
  • ).

23
  • Other Helpful Hints
  • Low grade astocytomas often change into high
    grade gliomas as they grow.
  • The craniotomy site(s) and incision markers are a
    reflection of where the mass traveled.
  • In late stage gliomas (especially glioblastoma
    multiformes), cancer cells often cross
    hemispheres. This makes them VERY difficult to
    treat.
  • Glioblastomas are ALWAYS STAGE IV.
  • Stage IV astrocytomas are essentially the same
    thing as a gliobastoma.
  • Grade IV tumors also have margins that are VERY
    hard to find. Many of them even grow tendrils or
    appendages (think octopus).
  • Despite the prognosis of stage IV tumors,
  • many people are living upwards of a year after
    their
  • diagnosis due clinical trials and new
    developments
  • in cancer research. However, they are eventually
  • terminal.

24
Treatment options What
they are and how the impact treatment
Understanding the cell cycle
  • Chemotherapy
  • Radiation
  • Radiosurgery
  • Traditional surgery
  • Bone marrow transplants
  • Gene therapy
  • Hormone therapy
  • Holistic approaches
  • Palliative Care

At each stage of mitosis, there is a built-in
check point. If cellular structure is
incomplete or incorrect, mitosis cannot occur.
Scientists rely heavily on these checking
points as opportunities to inhibit cancer cell
divisions with various types of medications.

Craniotomy 101
Photos www.brain-surgery.us
Burr Holes initiating removal
The leathery dura mater Arachnoid
mater underneath of the
skull flap
  • The patient is made NPO for appx 12/24 hours
    except meds
  • The patient is wheeled to the O.R. and sedation
    is given
  • Utensils and hardwear are counted pre-op
  • Any necessary hair is shaven off
  • The patients head is clamped into a tripod (of
    sorts). Pins secure the head into the vice
    (these small wounds will heal in 1-2 days).
  • A line is drawn on the skin to demarcate the
    incision n the scalp
  • The scalp is cut open and peeled back as far as
    need be
  • The skull is marked to demarcate the size/shape
    of the bone flap
  • Burr holes are made with small drills to begin
    skull flap removal
  • A bone cutting blade cuts the remainder of the
    skull flap
  • Necessary tissue is excised.
  • The skull flap can either be left off or replaced
    dependent upon the amt of swelling incurred.
  • Utensils/hardwear are counted and recounted

26
Common craniotomy terms
  • Cranitomy Term used for cutting open the brain
    to alter structure or function. Does not usually
    involve removing brain tissue.
  • Craniectomy Term used for opening the brain and
    removing what was normal brain tissue. (Tumors
    are NOT considered part of the normal brain.
    Therefore, tumor removal is not considered a
    craniectomy).
  • Partial resection Removal of part of the
  • tumor (amount is usually unspecified in the
    chart
  • but the patient /family usually knows!)
  • Gross/Total Resection Removal of what the
    neurosurgeon believes is the whole tumor.
  • While a total resection is great, be careful
  • This may NOT mean the patient is cancer free.
  • Chemo or radiation may need to follow.

27
Most common complications of undergoing a
crani
  • Risk of infection of the brain itself
  • Risk of infection of the skull flap
  • Swelling (external or internal)
  • Hydrocephalus (many patients require a shunt if
    this become uncontollable. These are known as
    Ventricular-Peritoneal Shunts or VP Shunts
  •  Development of seizures
  •  Development of diabetes insipidus (from
    corticosteroids used to reduced swelling)
  •  Cerebral Hemorrhaging
  • Stroke
  • Weakness/paralysis/sensory loss due to focal
    damage
  • Swallowing difficulties/aspiration pnuemonia
  • Falls post-op

28
Chemotherapy Medications that either cause
total cell death, or interrupt the cell cycle.
Apoptosis The suicide gene in cells that
cause normal cell death. This is the mechanism
that is often inhibited with cancer. Apoptosis
is inhibited and/or not allowed to occur.
The two types of chemo drugs
  • Cytotoxic drugs
  • Drugs that lead to cell death
  •          Antimetabolites drugs that stop the
    body from making enzymes needed for tumor
    growth. Most common Mthotrexate (MTX). Risk
    They also inhibit normal enzyme production,
    possibly leading to protein deficiency and/or
    anemia.
  •    Hormones Used to block proteins needed
    for tumor growth. Most common tamoxifen (used
    primarily in breast CA)
  •          Anti-tumor antibiotics stops cell
    growth by changing the environment around the
    cell. Most common Rapomycin
  •          Mitotic inhibitors plant based
    inhibitors of proteins that cancer cells need to
    breed. Most common Taxol
  •          Alkylating agents drugs that bond to a
    malignant cells DNA to prevent reproduction,
    and/or prevent a damaged cell from fixing
    itself. Most common carboplatin, cysplatin,
    Temodar
  •          Steroids Primary purposes is to
    reduce inflammation. Inconsistent research
    states they may have some impact on tumor
    cells.However, effectiveness is well documented
    in CNS lymphoma (ABTA,2010)
  •  
  • Cytostatic drugs
  • (sometimes called targeted therapy
  • Drugs that prevent tumor growth or mitosis
  •          Angiogenesis the process by which a
    tumor grows a new blood supply to feed itself .
    Medications called anti-angiogenesis inhibitors
    prevent new blood vessels from growing around a
    tumor. Most common interferon, thalidomide.
    Often combined with another form of chemo to
    attack the tumor and its blood supply.
  •          Drugs to prevent tumor resistance
    many tumors can become immune to medications as
    they change at the cellular level. These drugs
    keep the tumor susceptible to the impact of meds.
    Most common guanine derivatives
  •          Growth factor inhibitors Meds that
    prevent critical proteins from feeding the tumor.
    Most common Gleevec (ABTA, 2010)

cells divide and reproduce at highly abnormal
rates. Cisplatin attacks the cell cycle, killing
them and reducing the size of tumors.

Methods of Delivery
Traditional methods of delivery
  • 1) Pill form
  • 2) Intrarteriorly (usually via port in the chest
    or the upper arm)
  • IV form
  • Intrathecally (directly into the spinal cord
    given via a catheter attached to the port)
  • Topically


31
More recently developed delivery systems
Intracavitary Patented by Gliadel Once a
tumor is removed/debulked, Gliadel wafers are
implanted, and line the cavity in which the tumor
used to sit. (Gliadel.com)
Pros Highly effective and permanent until
saturated medication runs out and they dissolve.
Constant dose of medication in direct contact
with malignant tissue. Cons Wafers can
sometimes become infected, thereby not
suppressing tumor growth as anticipated, and
causing infections and/or abscesses. Requires a
subsequent craniotomy for removal if they become
infected. Dosage cannot be changed once they are
implanted.
1)      Convection enhanced therapy (CED) one
of the newest methods of delivering chemo. Uses
the natural physics of the body (gravity/constant
need to equalize pressure) to circulate/push
medications into brain tumor tissue more
naturally. More easily navigates through the
blood brain barrier by sneaking through with
other fluids. Requires a shunt/port (at least
one, sometimes more) to inject. Cool fact
Research is being done in attempts to include
tracers that will allow them to observe real
time movement of the drugs in and around a tumor.
These tracers would be mixed with the drug as it
is injected into the patients system (ABTA.com).

Chemo brain. Yes, its real.
  • Definition Mild to moderate cognitive-linguistic
    changes that occur either during or after a
    chemotherapy regiment. Also known as chemo fog.
  • Includes the following
  • Short term memory loss 7) Fatigue (physical and
    mental)
  • Difficulty concentrating 8) Short attention
    span
  • Being unusually disorganized 9) Taking longer
    than normal to complete routine tasks
  • Difficulty with word finding 10) Trouble with
    verbal memory (recalling a conversation)
  • Difficulty learning new skills 11) Trouble with
    visual memory (Mayo Clinic, 2009)
  • Difficulty multitasking
  • Interesting fact One of very few medical terms
    that originated and was adopted from
  • the outside in. Now recognized in all medical
    dictionaries and med schools as a
  • legitimate side effect of treatment. Recognized
    initially without any scientific data
  • and/or definitive diagnostic studies (Mayo,
    2009).
  • Nomenclature was coined by breast cancer support
    groups (actual date unknown, but emerged sometime
    post the year 2000).

36
The study survivors were waiting for
  • Title Self-reported cognitive impairment in
    patients with cancer.
  • Funded by The American Society of Clinical
    Oncology
  • Published in Journal of Oncology Practice, 2007
  • Sample 595 patients in multiple centers
    undergoing treatment for solid tumors (locations
    unspecified).
  • Treatments included radiation, chemotherapy, or
    both.
  • Method Patients given a rating scale between
    0-10. Rated themselves on a) concentration and
    b) memory
  • 0 not present / 10 as
    bad as you can imagine
  • A score of 7 or more deemed as
    severe
  • Key terms
  • Baseline before treatment began (T1)
  • Pt report of being at their worst during
    treatment (T2)
  • 6 months after treatment ended (T3)
  • Meaningful Outcomes (The take home message!)
  • Cognitive deficits were less severe in those
    patients receiving ONLY radiation

37
Radiation therapy How it works
  • 5 purposes of radiation
  • To shrink a tumor
  • To eradicate a tumor
  • For palliative reasons
  • For prophylaxis
  • Preferred in pediatrics

Many patients are on medications called
radioenhancers. These drugs make tumors
more susceptible to the impact of radiation.
Radiation is measured in rads (radiation
absorbed dose). Average dose appx 200
rads/cycle (computing case.org) RADIATION IS
CUMULATIVE
  • Types of radiation therapy
  • Conventional radiation Delivers full dose
    radiation to the tumor itself and the margins
    round it. Most common type of therapy given for
    primary brain tumors. Problem it is NOT
    selective in what it hits. Normal brain tissue is
    inevitably affected. Often given in slow daily
    doses. Radiation is CUMULATIVE and desired dose
    can take several weeks to reach. Beams also
    disperse easily when they hit the skin (ABTA,
    2010).
  • Radiosurgery Frequently used for secondary
    tumors that have metastasized to the brain.
    Generally used on masses that are easily seen,
    and where the likelihood of unseen tumor cells is
    low. (ABTA, 2011).
  • Prior to radiosurgery Patients will undergo
    radiation mapping, be fitted for a facemask (if
    the tumor is in the brain) and undergo 1-2 dry
    runs prior to actual radiation delivery. Often
    put on steroids, anticonvulsants or both.

38
  • Units of Measurement
  • Radiation doses for cancer treatment are measured
    in a unit called a gray (Gy).
  • A Gray the amount of radiation energy absorbed
    by 1 kilogram of human tissue. (NCI.com)
  • Most cumulative doses are between 20-60 Gys.

  • Fractionation
  • The term used for giving small doses at a time.
  • For adults, patients range between between 1.8
    2 Gy fractions per dose. A common schedule is
    this dosage given 5 days a week for x number of
    weeks.
  • A common dose for children is between 1.5-1.8 Gy
    per dose..
  • Sometimes two fractions/day are given toward the
    end of a treatment regiment. This is known as a
    boost since small tumors at the end of
    treatment can repopulate more quickly.

39
What terms are used for radiation
measurements? Radiation is measured in different
ways. Measurements used in the United States
include the following (the internationally used
equivalent unit of measurement follows in
parenthesis) Rad (radiation absorbed dose)
measures the amount of energy actually absorbed
by a material, such as human tissue (Gray100
rads). Roentgen is a measure of exposure it
describes the amount of radiation energy, in the
form of gamma or x-rays, in the air. (Roentgen
equivalent man) measures the biological damage of
radiation. It takes into account both the amount,
or dose, of radiation and the biological effect
of the type of radiation in question. A millirem
is one one-thousandth of a rem (Sievert100
rems). (www.epa.gov)

Tobacco and radiation
  • It's not from just from burning tobacco, -- it's
    from inhaling radiation absorbed by the tobacco
    plant while it grows in the field.
  • Radioactive materials in the atmosphere adhere to
    sticky tobacco leaves. The materials remain on
    the plant throughout the manufacturing process.
    The use of Apatite--a phosphate
    fertilizer--increases the radiation absorbed by
    the tobacco plant.
  • The lead-210 and polonium-210 radiation emitted
    by the tobacco smoke is trapped in the lungs of
    the people exposed to it.
  • Tar from the smoke also builds up in the lungs
    and enables them to trap the radiation more
    efficiently. Over the course of decades of

Type 2 linear accelerator (lineac). Can be
used for both conventional radiation delivery or
radiosurgery. Beams can be computerized to meet
the exact shape of a tumor
Type 1 Cobalt 60 systems radiation beams. Most
common type Gamma Knife 201 beams focused
into one area of the brain
Type 3 Cyclotrons. Nuclear reactors capable of
smashing atoms to release harnessed proton,
neutron and helium ion beams

Home / On the Cutting Edge of Care On the
Cutting Edge of Care by Susan Wessling Minority
Nurse Writer When Evelyn Badran, CNRN,
graduated from high school in 1980, she had no
idea that a career in nursing was in her future.
Today, nearly three decades later, she is not
only an experienced and successful nurse but is
literally working on the cutting edge of cancer
care. As coordinator of the Gamma Knife suite at
the Neurologic Orthopedic Hospital of Chicago
(NOHC), Badran helps treat brain tumor patients
with a highly advanced technology that was
virtually unheard of 15 years ago. Gamma Knife
radiosurgery is a high-precision radiation
delivery system that is used to treat abnormal
brain tissue in a single session without surgical
incisions. A helmet- like frame is attached to
the patients head using pins and local
anesthetic, allowing targeted radiation to
destroy the cancer cells while minimizing the
effects on healthy surrounding tissue. Because
the procedure is non-invasive and virtually
painless, it causes little discomfort or
post-operative recovery pain and patients can
return to their usual routines almost
immediately. I know I am helping to make a
difference in patients lives with the help of
this amazing equipment, Badran says. While she
now spends her days providing state-of-the-art
nursing care, her ambitions as a teenager were
quite different. Growing up in La Paz, Bolivia,
Badran originally wanted to become an
architect. She attended a Catholic high school
that required all students to provide community
service to a population in need. I chose to
volunteer in an orphanage, she recalls. After
my service requirement was completed, I
couldnt separate myself from the children at
the orphanage. I just needed to be there and be
helping. Somehow it captured my heart. In that
sense, I knew I had a passion to help people, but
nursing was never in my mind. Two years after
graduating from high school, Badran immigrated to
the United States with her brother. Leaving her
parents behind, she settled in Chicago, where her
aunts, uncles and cousins were living. Like many
immigrants, she immediately felt the impact of
the language barrier. My English was very
basic, she says. When my brother and I moved
here, our uncle told us, You are not going to
watch any television in Spanish. You need to get
used to the English language. So that is what
we did. An avid reader, Badran was upset when
she bought a book written in English and found
she could not read it. This made her determined
to work harder on becoming proficient in her new
language. I started paying more attention. I was
very strict with myself. I focused on what I
wanted, she explains. I had been here maybe
five months and I took ESL (English as a second
language) classes. By the eighth month, I was
reading that book. Still, Badran initially found
it difficult to adjust to American culture. Life
over here is very different compared to life in
my home country, she says. I lived in a main
city in Bolivia, but it was definitely a lot
smaller than Chicago. The way life is over here,
it demands more. It seems like you are working
all the time. You dont have time to do
everything you want to do. In South America, it
is a little more relaxed. Here families tend to
separate, live apart, she continues. In my home
country, families basically stay together.
Parents with adult children and their families
can all live in the same house. That was another
thing that was hard to adjust to when I came
here. Following Her Heart Despite her early
difficulties, Badran grew to love the culture in
America. She particularly appreciated the
opportunities for education. Enrolling in
college, she took the prerequisites for her
associates degree while trying to decide on a
major.

Side Effects of Radiation
  • Impact during treatment
  • Hair loss in the treatment area
  • Mouth problems
  • Nausea and vomiting
  • Sexual changes
  • Swelling
  • Trouble swallowing
  • Urinary and bladder changes
  • Diarrhea
  • Weight gain or weight loss (often due to
    simultaneous need for steroids)
  • Note Late side effects may first occur 6 or
    more months after radiation therapy is over. They
    vary by the part of your body that was treated
    and the dose of radiation you received. Late side
    effects may include infertility, joint problems,
    lymphedema, mouth problems, and secondary cancer
    (NCI, 2011)

46
Radiation Recall
  • What it is An inflammatory reaction that occurs
    in patients who have received chemo AFTER
    radiation (NIH.gov)
  • The chemo essentially reactivates the EFFECTS
    of the radiation (not the radiation itself).
  • May occur days, weeks, months or years after
    treatment
  • Unknown cause/triggers

New Cutting edge options Novocure
(www.Novocure.com)
  • A noninvasive technology in the clinical trials
    stage
  • Referred to as TTF therapy TTF Tumor
    Treating Fields
  • An Anti-mitotic treatment that slows or reverses
    tumor progression
  • NOT an electrical stim unit!!! No electrical
    impulses are given
  • Only side effect reported is minimal skin
    irritation at the transducer site..
  • All cells are polarized. Novocure tampers with
    the polarity of the cells, causing them to
    actually REPEL each other instead of ATTRACT each
    other.
  • Used in Glioblastoma in addition to chemo,
    radiation, surgery, etc.
  • Also used in small cell lung cancers.

survivor previously seen at St. Jude Medical
Center (Fullerton) and now receiving her
Novocure treatment at UC Irvine. She also
receives Avistatin infusions every other week.
Per her, this is how the system works The
Novo is worn 24/7 plugged into a wall socket or
battery pack. It's quite a contraption. 4 arrays
are place in specific locations on my head and
the transducers emit opposing positive and
negative impulses to confuse cancer cells so they
don't develop. I know there is a better
scientific explanation, but I though the Cliff
Note version was better here. There's quite a bit
of info on-line about it.
50
Immunotheraputic Vaccines These trigger the
bodys immune system to beef up the immune
system to fight cancern, or to restart a
suppressed system (ACS.org)
  • Checkpoint blockade drugs
  • Cancer cells are smart, and can sometimes fool
    the immune system into not attacking them.
  • They essentially take advantage of the immune
    systems ability to discriminate healthy from
    non-healthy cells, and its failsafe to NOT
    attack normal cells.
  • Checkpoint blockade drugs take the brakes off
    and tell the immune system to go after the cancer
    cells again.
  • CTLA-4 and PD1
  • Adoptive Cell Transfer Therapies
  • Done by removing a patients own cells,
    re-engineering them and programming them to
    attack cancer and then reinserting them back into
    the patients body (ACS.org)
  • Highly personalized treatment
  • Very expensive and not easily duplicated
  • Still in the clinical trials phase.

51
Hyperthermia The impact of heat
  • Can cause changes at the cellular level and make
    cancer cells more sensitive to treatment
  • If high enough, can kill cancer cells completely
    (ACS)
  • High Heat
  • (aka thermal ablation or local hyperthermia)
  • Uses radio waves, microwaves or ultrasound waves
    to cook the tumor.
  • HIFU High Intensity Focused Ultrasound
  • Can be external or internal
  • Usually used with recurrent tumors or patients
    who cant tolerate sx
  • RFA (Radio Frequency Ablation) is most common
  • Side effects bleeding, blood clots, pain,
    tissue damage, blistering
  • Low Heat
  • (aka regional hyperthermia
  • Usually involves heating a cavity in the body
  • Combined with radiation or chemo
  • Difficult due to the need to sustain an exact
    temperature in a large area.
  • Side effect include problems with the heart,
    blood vessels and major organs.
  • Effective for cancers just below the skin.
  • Perfusion Removing blood, heating it, then
    pumping it back in.
  • Increasing core body temp to appx 102 using a
    special tent, thereby triggering the body to
    fight infection (www.Lemmo.com)

with a beam of light traveling along fiber optics
for photodynamic therapy. Its source is a laser
beam which is split at two different stages to
create the proper therapeutic wavelength. A
patient is given a photosensitive drug that is
absorbed by cancer cells. During the surgery, the
light beam is positioned at the tumor site, which
then activates the drug that kills the cancer
cells, thus photodynamic therapy (PDT).

55
Clinical trials show
  • Food and Drug Administration (FDA) categories
    for describing the clinical trial of
  • a drug based on the study's
    characteristics, such as the objective and number
    of participants.
  • There are five phases Phase 0 Exploratory
    study involving very limited human exposure to
    the drug, with no therapeutic or diagnostic goals
    (for example, screening studies, microdose
    studies). Phase 1 Studies that are usually
    conducted with healthy volunteers and that
    emphasize safety. The goal is to find out what
    the drug's most frequent and serious adverse
    events are and, often, how the drug is
    metabolized and excreted. Phase 2 Studies that
    gather preliminary data on effectiveness (whether
    the drug works in people who have a certain
    disease or condition). For example, participants
    receiving the drug may be compared with similar
    participants receiving a different treatment,
    usually an inactive substance (called a placebo)
    or a different drug. Safety continues to be
    evaluated, and short-term adverse events are
    studied. Phase 3 Studies that gather more
    information about safety and effectiveness by
    studying different populations and different
    dosages and by using the drug in combination with
    other drugs. Phase 4 Studies occurring after
    FDA has approved a drug for marketing. These
    including postmarket requirement and commitment
    studies that are required of or agreed to by the
    sponsor. These studies gather additional
    information about a drug's safety, efficacy, or
    optimal use. (See also Study Phase data element
    on ClinicalTrials.gov.)

The financial side of things
  • The pharmaceutical business is the second most
    lucrative business in the U.S. Oil is the first.
  • Eleven of the twelve cancer drugs the Food and
    Drug Administration approved for fighting cancer
    in 2012 were priced at more than 100,000 per
    year, double the average annual household income,
    according to a report by the Journal of National
    Cancer Institute. (Kantarjian, abcnews.com)
  • Most insurance companies have an 80/20 or 90/10
    payment set up. Out of pocket costs are
    generally 10,000/year PER MEDICATION considering
    the above costs.
  • The out of pocket maximum for tax purposes is
    6,700/year BEFORE you can include medications as
    an itemized deduction.
  • Many cancer patients have to either decrease
    their work load or go on long term disability.
    Once sick days and short term leaves have been
    exhausted, state disability will usually provide
    patients with appx. 60 of their gross income.
  • Most clinical trials are NOT covered by major
    insurance companies as they are not yet proven to
    work. The sponsor of the clinical trial may
    provide some compensation, but it is usually a
    pittance compared to the financial overhead
    patients experience.

57
Common Costs incurred
  • Immediate costs
  • Subsequent costs

  • Palliative care improves the quality of life of
    patients and families who face life-threatening
    illness, by providing pain and symptom relief,
    spiritual and psychosocial support to from
    diagnosis to the end of life and bereavement.
    Palliative care
  • provides relief from pain and other distressing
    symptoms
  • affirms life and regards dying as a normal
    process
  • intends neither to hasten or postpone death
  • integrates the psychological and spiritual
    aspects of patient care
  • offers a support system to help patients live as
    actively as possible until death
  • offers a support system to help the family cope
    during the patients illness and in their own
    bereavement
  • uses a team approach to address the needs of
    patients and their families, including
    bereavement counseling, if indicated
  • will enhance quality of life, and may also
    positively influence the course of illness
  • is applicable early in the course of illness, in
    conjunction with other therapies that are
    intended to prolong life, such as chemotherapy or
    radiation therapy, and includes those
    investigations needed to better understand and
    manage distressing clinical complications
  • (World Health Organization/WHO _at_

The palliative care team provides access to
services such as
  • Massage therapy
  • Aromatherapy
  • Acupuncture/acupressure
  • Pet therapy
  • Organic/holistic approaches to pain mgmt
  • Deep breathing techniques
  • Eastern Medicine (e.g. yoga, Thai Chi, herbal
    medicines)
  • Counseling regarding physical/emotional coping
  • Understanding legal or health care language
  • Financial resources
  • Note While palliative care specialists may not
    actually PROVIDE these services, they have the
    names/contacts of people who do! Most services
    require an MD order.

64
More about Palliative Care
  • ANY health care professional can make a referral
    to the palliative care team or palliative care
    nurse
  • Referring does NOT require an MD order
  • It has been heralded for improving quality of
    life
  • Hospice is under the palliative care umbrella,
    but it is NOT THE ONLY SERVICE PALLIATIVE CARE
    PROVIDES!
  • Hospice is used when patients are terminal,
    usually having less than 6 months to live. It is
    usually covered by insurance.
  • Palliative nurses are generally RNs. It is a
    specific type of nursing requiring specialty
    training.
  • They are some of the coolest, most innovative
    people youll ever meet!
  • Often have some quirky, untraditional methods of
    treating symptoms and side effects.
  • They are direct, generally do not mince words
    and are usually well-seasoned folks who have lots
    of life experience.

Symptoms and Diagnosis in Kris words
  • My symptoms began subtly. My dad and
    brother had migraines, so when I got a headache
    that lasted 6 weeks, I suspected I was joining
    the migraine club. On the Monday after
    Thanksgiving, 2012, as I was preparing to go to
    dinner with friends, I decided to lie down for
    "just a minute." My husband discovered me lying
    down, told me to put on shoes, and insisted we go
    to the Emergency Dept.
  • From there, my memories get vague. I was
    admitted to the ICU after an MRI and awoke there
    the next afternoon after brain surgery. My
    husband and mother made the decision to proceed
    with the surgery as I was not aware at all. The
    neurosurgeon told my family that I had a large
    (egg-sized) mass in the right side of my brain.
    As it was glioblastoma, it was "a matter of life
    and death" so they gave the go-ahead, for which I
    am eternally grateful.
  • The first time I saw the neurosurgeon was the
    day after the surgery. I have had an Oncologist
    for MANY years, so seeing her was not a shock.
    The surprise came in the Radiation Oncologist and
    what she had planned for me. I had 30 days of
    brain radiation, complete with "fencing mask",
    accompanied by oral chemotherapy. I had a
    re-growth of the tumor in 2013 but saw all the
    doctors prior to surgery that time.

Reaction to the C word
  • Everyone I know cried, pulled up their
    grown-up pants, and decided to fight this thing.
    I have been completely surrounded by a safety net
    of love, support, compassion, meals brought in,
    folks driving me around, cards, phone calls, pep
    talks, and help.
  • I had breast cancer in 1983 and 1996, so the
    "C" word was not too difficult for me, but I was
    most stunned that it wasn't metastatic breast
    cancer, rather a whole new mountain to climb. The
    most daunting part has been the statistics, cure
    rate (or lack thereof) and possibility of
    survival. I know 2 things miracles happen, and
    10 of people with this particular cancer
    survivor more than 5 years AND I intend to be in
    that group!

72
Medical Course
  • After 7 days of recovery from surgery I was told
    I would be going to rehab, which I thought would
    be with older folks in diapers passing a beach
    ball around, or group sing-alongside. It turned
    out to be a positive experience, except that my
    life had totally left my control. I was given a
    daily schedule of physical, occupational, speech,
    recreational therapies, none of which I thought I
    needed! It turned out
    I was wrong and all were very
    informative and helpful.

73
Treatment and side effects
  • While in the hospital, I was on anti-seizure
    medication (can't remember name) and steroids.
    When I came home I started Temodar orally, daily,
    in conjunction with radiation. That's when by
    blood (found) took a digger. They think it was
    due to suppression of my bone marrow from
    Adriamycin, Cytoxin, 5FU therapy for the breast
    cancer in the 80s. I received 3 transfusions of
    platelets and daily Nupagen (sp?) injections to
    try to bolster me up.
  •  St Jude doesn't have a neuro-oncologist so I
    was referred to UC Irvine specialists to
    determine an alternate therapy. It was
    recommended that I use NovoCure TTF ( tumor
    treatment fields) along with Avastin infusions
    every other week.
  • Note The most common seizure meds are Keppra
    (very expensive and not always covered by
    insurance) and Dilantin. Dilantin levels need to
    be monitored regularly when on this med.. You
    also cant drive while you have a dx of a seizure
