Retrospective analysis of surgical resection after induction chemotherapy for patients with T4b squamous cell head and neck cancer

Background. Standard treatment of patients with T4b squamous cell head and neck cancer (T4b-SCHNC) is concomitant chemo-radiotherapy (CT-RT). Recent Phase III trials with Taxane containing induction chemotherapy (IC) suggest that IC could also play a role in this setting. The value of resecting the residual mass after IC and before RT is not yet clear in this context. Methods. We present the results of a retrospective analysis. Results. Between 1984 and 2001, 113 patients (patients) with T4b-SCHNC were treated at our institution with IC. Four patients dead during IC and 57 patients achieved a complete or a >90% partial response at primary and proceeded to definitive RT (or concomitant CT/RT). Surgical resection was reconsidered after IC and before RT in the other 52 patients. Surgery was performed in 13 of them: in 7 patients resection was R1, all of them had loco-regional progression (2 also developed systemic metastases) and median OS after surgery was 21 months, with no patient alive at 48 months.
