title: Advanced carcinoma of the larynx: results of surgery and radiotherapy without induction chemotherapy (1980-1985): a multivariate analysis.
abstract: OBJECTIVE
  Induction chemotherapy has been proposed in the case of advanced laryngeal cancer in order to preserve laryngeal function in those patients who are complete responders. To clarify the treatment policies, a retrospective multicentric analysis of 116 patients with advanced carcinoma of the larynx treated by radical surgery and postoperative radiotherapy was carried out in order to evaluate prognostic factors for local control and survival.
  
  
  METHODS
  Between 1980 and 1985, 116 patients with Stage III squamous cell carcinoma of the larynx underwent radical surgery and postoperative radiotherapy with a curative intent. Treatments were very homogenous, and doses delivered were in the range of 50-65 Gy according to nodal involvement and surgical margins status.
  
  
  RESULTS
  The local recurrence rate and the local disease-free survival rate at 5 years were 22.5% and 76.3%, respectively. Actuarial survival at 5 years was 68.3% with 44 patients still alive with no evidence of disease (NED) with more than 5 years follow-up. For both overall survival and relapse-free survival, cervical node involvement with capsular rupture was found to be the only significant adverse pronostic factor in univariate and multivariate analysis. No other parameter was predictive either for local recurrence or for survival.
  
  
  CONCLUSIONS
  Local prognosis and survival depend largely on nodal involvement and capsular rupture while increasing doses of radiation strategy is likely to reduce the risk of local and nodal recurrence. Preservation of functional larynx is certainly an important goal to achieve when treating advanced carcinoma of the larynx, provided that local failure rate and survival be similar. In the unique randomized study previously published in the literature comparing radical surgery and postoperative radiotherapy to induction chemotherapy and radiotherapy, the local-regional failure rate was drastically increased in the chemotherapy arm. Other results from well-designed controlled studies are awaited before recommending systematic induction chemotherapy and larynx preservation in complete responders. On the other hand, testing synchronous or alternated chemotherapy vs. induction chemotherapy may address the pending questions about the optimal treatment of advanced laryngeal carcinoma.
