Title: Management of Laryngeal Cancer


1
Management of Laryngeal Cancer
  • Cees A. Meeuwis, MD, PhD
  • Erasmus University Hospital Rotterdam, the
    Netherlands

2
Cancer of the larynx
  • 3.5 of all new malignancies diagnosed annually
    worldwide
  • SCCA of the larynx most frequent malignant tumor
    of the upper aerodigestive tract in europe
  • Worldwide distribution
  • General incidence 2.5-17.2/100,000 per year
  • Highest in Basque country, Spain (20.4) and
    lowest in Qidong, China (0.1)
  • High incidence in Brazil, North Thailand, France
    and Poland
  • (Parkin,1992Shah,2003)

3
Laryngeal cancer in the Netherlands
  • 600 new cases per year (?? 5 1)
  • stage I-II 80
  • stage III-IV 20

4
  • Head and neck division of the Erasmus Medical
    Center
  • 750 new patients per year
  • 125-150 patients with laryngeal cancer

Introduction

Early stage Larynx carcinoma
7
T3 larynx carcinoma
8
Late stage larynx carcinoma
9
initial treatment options for cancer of the
larynx
  • T1 radiotherapy / surgery (CO2 / partial
    laryngectomy)
  • T2 radiotherapy / surgery (CO2 / partial
    laryngectomy)
  • T3 radiotherapy /chemotherapy/ surgery /
    partial laryngectomy)
  • T4 surgery(total) radiotherapy /
    chemoradiotherapy

10
University Hospital Rotterdam treatment protocol
  • T(cis) laser surgery
  • T1 radiation
  • T2 radiation
  • T3 radiation (chemotherapy)
  • T4 surgery (laryngectomy) radiation
  • chemoradiation

66-70 Gy in 2 Gy fractions 5-6 x per week
11
Radiotherapy for T1/T2 glottic carcinoma
  • Local control rate approximating 90 for T1

  • 70 to 80 for T2
  • 5 year local control T1a 94
  • T1b
    93
  • T2a
    80
  • T2b
    72
  • (Spriano, 1997
    Fletcher 1994, Mendenhall, 2001)

  • Voice quality after radiotherapy tend to be less
    when compared to pre-radiotherapy but almost
    normal 2-3 years after treatment

    (Verdonck,1999Hirano,1994Heeneman,1994)

12
Treatment of T1/T2 glottic carcinoma
  • No randomised trials comparing laser with
    radiotherapy and surgery
  • Retrospective studies comparing these modalities
    have shown to result to similar local control
    rates.

13
Surgical optionsfor small T1 lesions
co2 laser
14
CO2 laserIndications
  • tumor limited to the glottis
  • complete visualization of the tumor is possible
  • normal vocal cord mobility
  • no extension of tumor into the anterior
    commissure

16
Endoscopic surgery(C02 laser) for T1/T2 glottic
carcinoma
  • Early studies showed local control rate from 88
    to 96
  • (Shapshay, 1990 Rudert, 1995 Mahieu 1999)

  • involved only T1a tumors

  • Recent studies show local control rates for
  • T1a 100
  • T1b 94
  • T2 91

  • minimal supraglottic/subglottic extension
  • (Gallo, 2002Pradhan, 2003)
  • Voice quality in general is preserved but
    would depend largely on the site of the lesion
    and amount of tissue removed
  • (
    MacGuirt, 1992 Rydell, 1995 Mahieu, 1999)

17
Endoscopic surgery(C02 laser) for T1/T2 glottic
carcinoma
  • Advantages of C02 laser over radiotherapy
  • Possibility of using the same modality (C02
    laser) for a recurrence
  • Radiotherapy can still be used as back-up
    treatment in cases of recurrence and second
    primaries
  • Less morbidity and less treatment time for the
    patient
  • Less cost

18
Management of T3 larynx carcinoma
  • Best therapeutic approach for T3N0 tumors is
    still uncertain
  • Patients may considered for chemoradiotherapy
    while selected patients may do just as well with
    conservation surgery with or without chemo or
    radiotherapy alone

19
Management of T3 glottic larynx carcinoma
  • 200 patients with T3N0 glottic ca treated with
  • Total laryngectomy with or without radiotherapy
  • Conservation surgery with and without
    radiotherapy
  • Radiotherapy alone
  • 5 year disease specific survival 67
  • 5 year overall survival 54
  • Locoregional control 74
  • Laryngeal preservation 70
  • All did not significantly differ according to
    treatment


  • (Sessions, 2002)

20
Management of locoregionally advanced larynx
carcinoma
  • General principles
  • Primary goal is curation
  • Organ sparing strategies should be considered
    even in late stages
  • Factors that would influence quality of life
    play an important role in the choice of treatment
  • functions of the upper aerodigestive tract

21
Surgical options
  • T3 N
  • T4
  • Recurrent disease
  • Total laryngectomy

Provox low-resistance, indwelling voice
prosthesis (retrograde insertion and replacement
system)
59
Indwelling vs non-indwelling voice prostheses
advantages and disadvantages
  • advantages
  • no replacement required by patient
  • shorter learning curve and little dexterity
    needed for daily care
  • more robust design longer device life
  • with increasing age (loss of dexterity/visual
    acuity) still applicable
  • disadvantage
  • patient stays dependent of clinician
  • Due to leakage through or araund the prosthesis

60
Comprehensive rehabilitation after total
laryngectomy is more than voice alone
  • The larynx is more than just a voice box.Due
    to its central position in the respiratory tract,
    its removal requires rehabilitation of all three
    systems depending on respiratory airflow, i.e.
  • vocal rehabilitation
  • pulmonary rehabilitation
  • olfactory rehabilitation
  • Rehabilitation of laryngectomized patients
    requires a multidisciplinary team effort in order
    to achieve optimal results and quality of life

Olfactory rehabilitationthe polite yawning
technique
62
Pulmonary Rehabilitation After Total Laryngectomy
  • Due to the disconnection of the upper and lower
    airways, conditioning (heating, moisturing,
    filtering) of the breathing air will not take
    place any longer
  • The considerable decrease in breathing
    resistance, leads to a shift of the equal
    pressure point to more periferal in the
    pulmonary tract, which has a negative effect on
    pulmonary physiology

65
Early postoperative application of the Provox HME
and Optiderm adhesive
Hydrocolloid adhesive is ideal for first
postop day application
66
Additional benefits of Provox HME use
  • Retention of approximately 60 of the daily water
    loss (500 ml excessive loss with stoma breathing
    instead of nasal breathing
  • More hygienic handling of stoma
  • More effective coughing andsputum clearance by
    deliberatelyclosing stoma and releasing
    thevalve while coughing
  • Filtering of dust particles

67
Factors for successful voice rehabilitation
  • Anatomy and morphology of the neoglottis
  • Motivation of the patient
  • Motivation of the multidisciplinary team
    (Otolaryngologist, Speech Therapist, Oncology
    Nurse)
  • Voice prosthesis any voice prosthesisis better
    than no voice prosthesis at all(our preference
    is Provox, becauseof its low resistance, easy
    replacement,reliable retention, and easy
    cleaning)

Voice rehabilitation in theErasmusmc Rotterdam
  • Primary prosthetic voice rehabilitation is the
    method of choice our hospital since 1989
  • Indwelling, low-resistance voice prostheses, such
    as Provox(2), are preferred, with a long term
    success rate of approx. 90
  • Voice prostheses are also applicable after
    extensive pharyngeal resection and reconstruction
  • Patients also are offered esophageal voice
    rehabilitation (success rate approx. 40)
  • Electrolarynx speech is considered a valuable
    back-up method, but is too seldom used at present

71
Rule of thumb
  • 2/3 of the patients only require replacement of
    the prosthesis, mostly for mild leakage (median
    device life 3-4 months)
  • 1/3 of the patients experience adverse events,
    which require special attention, but mostly are
    easily solvable
  • these adverse events are seen in only 1 out of 9
    (10.7) replacements
