2Testicular Cancer
3Germ Cell Tumors
- Most common Solid Tumor in men 20-35
- 1 of cancers in males
- Great impact on years of life saved
- 95 arise in testis
- 5 are extra-gonadal mediastinum,
retroperitoneum, pineal body - Model of a Curable Cancer even in advanced stage
- Model of a Cancer with Tumor Markers playing a
crucial role in management
4Risk Factors
- Age
- Family history
- Personal history
- Cryptorchidism (undescended testicle)
- Association with Infertility (mild)
- Klinefelters syndrome
5Age at presentation
6Symptoms
- Painless lump or swelling of testicle
- Pain or discomfort in a testicle or the scrotum
- Breast tenderness or growth
- Symptoms of advanced cancer
- lower back pain,
- abdominal pain,
- shortness of breath,
- chest pain
7How is Testicular Cancer Diagnosed?
- Physical examination
- Ultrasound of Testis
- Blood tests / tumor markers
- Diagnosis is confirmed by surgically removing the
testicle - Needle biopsy not used (except in very specific
situations) - CTS of Chest, Abdomen and Pelvis
- No role for MRI.
- Mild role of PET (only in Seminoma)
8DICTUM FOR ANY SOLID SCROTAL SWELLINGS
- All patients with a solid testicular mass should
be regarded as malignant, unless proven otherwise
9Radical inguinal orchiectomy
- Most men are still able to have children after
the removal of one testicle - No effect on sexual function
- (men with sexual problems after surgery should
have their testosterone level checked) - Some men may choose to have an artificial
testicle implanted
10Histologic Subtypes of GCT
- SEMINOMA (40)
- Classical (32)
- Anaplastic (4)
- Spermatocytic (4)
- NON SEMINOMA (60)
- Embryonal Ca (25)
- Teratoma (25)
- Yolk sac Tumor
- Choriocarcinoma
Mixed GCT 40
11Staging
- Serum tumor markers (S) AFP, ß-HCG, LDH
12Tumor Markers
- AFP
- Half-life 5-7 days
- Produced by several Non Seminoma subtypes
(embryonal, teratocarcinoma, yolk sac, mixed
tumors) - Never produced by Seminoma or pure
choriocarcinoma - Falsely elevated in liver dysfunction, viral
hepatitis and ETOH - ß-HCG
- Half-life 24-36 hours
- Produced by syncytiotrophoblastic tissue
- All choriocarcinomas, 40-60 embryonal, 5-10
seminoma - Falsely elevated in hypogonadism and marijuana
use - LDH
- Most useful in advanced seminoma when other
markers are not ? - Many false positives
13How is Testicular Cancer Treated?
- Depends on stage of cancer and type of tumor
- More than one treatment may be used
- Surgery
- Active surveillance
- Radiation therapy
- Chemotherapy
- Patients should talk with their doctor about
whether treatment plan could affect sexual
function and fertility before treatment begins
14Seminoma
- Tend to remain localized or spread only to LN
- The disease spreads in an orderly fashion
retroperitoneal LN (SII). Mediastinal/supraclavi
cular LN (SIII). Lung and then non pulmonary
(brain/bone/liver) - If LN lt1cm repeat in 6w if normal ? follow marker
decline to distinguish between stage 1 and
disseminated disease. - Tumor marker analysis should be performed before
surgery and, if elevated, 7 days after surgery to
determine the half-life kinetics. Tumor markers
should be monitored until normalization.

21Stage I Seminoma adjuvant RadiotherapyClassical
Hockey Stick Field
22Adjuvant radiotherapystage I seminoma
- 22.5-25 Gy ( 3 weeks of treatment)
- Target Paraaortic Ipsilateral Pelvic Nodes
- Relapse rate 0-2
23Hadassah experience in stage Iadjuvant
Radiotherapy
- 36 patients with stage I seminoma
- Post orchiectomy hockey stick irradiation
- 22.5-24 Gy in 1.5 Gy fractions
- Testicular shell was always used
- Semen preservation was recommended to all
patients
24Outcome
- Median follow-up 98 mo
- No recurrences!
- One contralateral second primary GCT
- No effect of Radiotherapy on fertility
25Fertility Outcome
- 13/36 were not interested in fertility
preservation - 1/36 was azoospermic prior to diagnosis
- 1/36 was oligospermic priot to diasgnosis
- 5/36 were lost to follow-up
- 10 pts successfully conceived w/o any
intervention - The oligospermic pt successfully underwent IVF
treatment - other pts have not yet tested their fertility
26Stage II Seminoma - Treatment
- Cancer has spread to lymph nodes in the
retroperitoneum, but not lymph nodes in other
parts of the body - Stage IIA 2 cm Radiotherapy
- Stage IIB 2-5cm Radiotherapy or Chemotherapy
- Stage IIC gt5cm Chemotherapy
- Prognosis gt 95 Cure
27Stage III-IV Seminoma - Treatment
28Stage I Non Seminoma Management
- Surveillance
- Adjuvant Chemotherapy
- Surgery RPLND (Retro Peritoneal Lymph Node
Dissection)
29Surveillance for Markers negative stage I Non
seminomas
- Appropriate for low risk patients
- Compliant patient
- No vascular/lymphatic invasion
- No dominant presence of Embryonal Carcinoma
- Regular physical examination, CT scans, chest
x-rays, and blood tests (Markers), performed
every few months for the first 2 years and less
often thereafter - Risk of Relapse is then 25
- At relapse excellent chances of cure with chemo
30Adjuvant Chemotherapyfor High Risk stage I NSGCT
- Definition of High Risk Stage I NSGCT
- Lympho-vascular invasion, or
- Embryonal Carcinoma Predominance ( 45)

impregnate their wives, and to father 34 healthy
children (1-4), without need to use their banked
sperm. - Overall Fertility Ratio 80 (85?)
35Retroperitoneal Lymph node dissection
- Major morbidity is ejaculatory dysfunction
- Modified nerve sparing RPLND preserves function
in gt 90 - Identify the sympathetic nerves
- Dissection is limited to below the level of the
IMA on the ipsilateral side only

- Based on tumor location, tumor spread, and serum
marker levels - 3 groups for both seminoma and non-seminoma
- Good risk
- Intermediate risk
- Poor risk
- Patients with poor-risk cancer still have about a
50 chance of successful treatment

44Cancer Treatment Chemotherapy
- Classical Protocol PEB
- Platinum (Cisplatinum)
- Etoposide (VP-16)
- Bleomycin
- Common Side effects may include fatigue,
infection, nausea and vomiting, alopecia. - Rare side effects hearing loss, skin marks,
numbness and tingling, lung damage, kidney
damage, cardiovascular disease, and secondary
cancers - Nowadays very little severe long term side
effects
