Abstract:
:Since its foundation in 1971, the RTOG has conducted a successful clinical research program in head and neck mucosal squamous cell carcinoma with 22 treatment protocols and one registry study which combined have accumulated data on over 5,500 patients. The RTOG was the first multicenter group to evaluate neoadjuvant chemotherapy before definitive radiation with its methotrexate study. Although the study was negative, RTOG has since conducted five pilot or phase II studies of neoinduction or concurrent chemotherapy with radiation therapy in patients with inoperable tumors. The last study showed that radiation concurrent with cisplatinum was tolerable with a suggestion of increased antitumor effect. In patients with potentially resectable tumors, RTOG has completed a pilot study of combination chemotherapy administered either before or after the surgery with radiotherapy. Based upon its findings, the treatment sequence, surgery-chemotherapy-radiotherapy, was chosen as the experimental arm for a new phase III study. This study was subsequently adopted by the head and neck intergroup mechanism as its study (INT 0034/RTOG 8503). RTOG has investigated the optimal timing of radiotherapy with surgery. The 7303 study established that postoperative radiotherapy achieved significantly better locoregional control but not improved absolute survival. Approximately 30% of the patients on each arm failed to complete both modalities. Even when comparison is restricted to patients who completed both modalities, postoperative radiotherapy still produced the better locoregional control. Efforts to overcome the limitations imposed by tumor hypoxia through use of carbogen (95% O2 and 5% CO2) breathing or the radiosensitizer misonidazole during radiotherapy have been unsuccessful. In a phase I study, RTOG showed that 15 to 18 sessions of sensitized radiation can be safely delivered with the new radiosensitizer SR 2508 in contrast to only six such sessions with misonidazole. This promising radiosensitizer is now being tested in a phase III trial. RTOG has also investigated variations in fraction size, fraction number, and total radiation dose. In the 7102 study, split-course irradiation achieved equivalent antitumor results as compared to continuous daily irradiation but with less social alteration and cost to the patient. In the hyperfraction pilot study 7703, twice a day irradiation with 120 cGys up to 6,000 cGys proved to be tolerable.(ABSTRACT TRUNCATED AT 400 WORDS)
