title: Radiation Therapy Oncology Group (RTOG) trials for head and neck cancer.
abstract: Clinical investigations for cancer of the head and neck, primarily tumors of the upper respiratory and digestive tracts, have been one of the most important components of the Radiation Therapy Oncology Group (RTOG) since its inception 30 years ago. Emphasis from the very beginning to the present time has been on altered fractionation. Studies of hypoxic cell sensitizers were also explored for many years. More recently, combinations of radiation therapy with cytotoxic chemotherapeutic agents, either sequentially or concurrently, have been a major focus. Although the majority of the trials have been for unresectable tumors, surgical adjuvant radiation therapy alone or combined with chemotherapy has also been an important activity. Combined modality trials emphasizing organ conservation have been carried out within the last decade. The RTOG represents a national and international resource for studies of cancer of the head and neck. Its results influence the care of patients and the clinical research environment.
