Abstract
With the goal of achieving functional preservation, one of the treatment strategies for patients with locally advanced squamous cell carcinomas of the head and neck is to initiate treatment with induction chemotherapy (CT) and decide the second therapeutic manoeuvre depending on the response. The objective of this study is to evaluate organ preservation capacity based on this therapeutic approach in patients with tumours of the oral cavity and oropharynx. A retrospective study of 246 patients with locally advanced carcinomas of the oral cavity or oropharynx (cT3-T4) initially treated with induction CT. After induction CT 28% of patients achieved a complete response of the primary location of the tumour, 43.1% a partial response greater than 50%, and 28.9% a reduction less than 50% or persistence. After the induction CT treatment 70 patients (28.5%) underwent surgical treatment, and 176 (71.5%) radiotherapy (RT) or chemoradiotherapy (CRT). Considering the patients treated non-surgically (n=176), organ preservation for patients with a complete response (n=66) was 65.2%, for those patients with a partial response greater than 50% (n=75) it was 30.7%, and for patients with a partial response less than 50% or persistence (n=35) it w...Continue Reading
