title: Correlation between response to cisplatinum-combination chemotherapy and subsequent radiotherapy in previously untreated patients with advanced squamous cell cancers of the head and neck.
abstract: Induction chemotherapy, followed by surgery and/or radiotherapy was utilized in patients with advanced squamous cell carcinoma of the head and neck. During these trials, the authors observed that response to chemotherapy predicts further response to subsequent radiotherapy. This study was comprised of 57 patients with 60 separate neoplasms who demonstrated less than complete response (partial or no response) to initial treatment with a combination chemotherapy containing cisplatin. Subsequently radiotherapy, either 5000 rad preoperatively or 6600 rad as definitive therapy, was employed. Forty-one of the 42 tumors with initial partial response to chemotherapy also responded to radiotherapy (97.6%). Only one of the 18 tumors that initially failed to respond to chemotherapy subsequently responded to radiotherapy (5.5%). This observation suggests that patients with head and neck cancer sensitive to initial chemotherapy share parameters that are also radiation sensitive.
