OBJECTIVE The feasibility and success of an intensive chemoradiotherapeutic protocol for patients with locally advanced, unresectable squamous cell head and neck cancer was tested in this limited-institution, Eastern Cooperative Oncology Group phase II pilot study. METHODS Between December 1987 and September 1989, 57 patients were entered onto this trial. The treatment protocol consisted of three courses of a 4-day continuous fluorouracil infusion, a single cisplatin bolus injection, and concurrent split-course radiotherapy. After 30 Gy of radiation and two chemotherapy courses, patients were evaluated for response and for the possibility of surgical resection. RESULTS Fifty-five of 57 registered patients are assessable for toxicity and 52 are assessable for response and survival. Toxicity was significant, but tolerable, although there were three toxic deaths. A complete response to this treatment was ultimately achieved by 77% of patients. Twenty-four patients remain relapse-free. The projected Kaplan-Meier 4-year relapse-free survival rate is 45% and the overall survival rate is 49%. Median relapse-free and overall survival durations are 26 and 37 months, respectively. Of the 28 treatment failures, 79% were locoregional. Fourteen patients underwent surgery. Six remain relapse-free. CONCLUSIONS This aggressive concurrent chemoradiotherapy protocol appears feasible within a cooperative group. Treatment results are promising and appear durable. A randomized phase III clinical trial is currently underway.

D012044 Regression Analysis Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.

D002294 Carcinoma, Squamous Cell A carcinoma derived from stratified SQUAMOUS EPITHELIAL CELLS. It may also occur in sites where glandular or columnar epithelium is normally present.

D002945 Cisplatin An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.

D003131 Combined Modality Therapy The treatment of a disease or condition by several different means simultaneously or sequentially. Chemoimmunotherapy, RADIOIMMUNOTHERAPY, chemoradiotherapy, cryochemotherapy, and SALVAGE THERAPY are seen most frequently, but their combinations with each other and surgery are also used.
