简要总结
To demonstrate whether addition of Concurrent chemotherapy to post-operative adjuvant radiotherapy OR shortening of duration of post-operative radiotherapy, by administering 6 fractions / week instead of 5 fractions / week improves local-regional control and / or overall survival in high risk, locally advanced, resectable, squamous cell carcinoma of oral cavity.
详细描述
Locally advanced, stage III and IVA, resectable, squamous cell carcinomas of oral cavity are conventionally treated with surgery, followed by post-operative radiotherapy. Local-regional recurrence remains the most frequent cause of failure of this treatment. The results of conventional therapy are dismal with five-year survival of less than 30% and 60-80% incidence of local-regional failure within 3 years. There are various known histological prognostic factors. The local-regional control and overall survival are extremely poor in high risk patients with these poor prognostic factors. In an attempt to improve the outcome of this high risk group, various alternative treatment policies such as addition of chemotherapy to radiotherapy or altered fractionation schedules have been tried. But till date, there is no alternative treatment modality with acceptable toxicity, available for these patients.
Aims Of Study: To demonstrate whether addition of Concurrent chemotherapy to post-operative adjuvant radiotherapy OR shortening of duration of post-operative radiotherapy, by administering 6 fractions / week instead of 5 fractions / week improves local-regional control and / or overall survival in high risk, locally advanced, resectable, squamous cell carcinoma of oral cavity.
Eligibility criteria: Locally advanced, stage III and IVA, resectable, squamous cell carcinomas of oral cavity with one of the following poor prognostic factors extracapsular nodal extension, involvement of > 2 regional lymph nodes, margin of resection with invasive cancer Extensive soft tissue and / or skin infiltration requiring major reconstructive procedure.
Peri-neural invasion with positive lymph node. Lympho-vascular embolisation with positive lymph node.
Trial Design The eligible patients will be randomly allocated to one of the three arms
