title: Integration of chemotherapy and radiation therapy for small cell carcinoma of the lung.
abstract: Two chemotherapy trials using cyclophosphamide, doxorubicin hydrochloride and high-dose vincristine sulfate with or without methotrexate have induced a 93% incidence of complete remission in limited disease presentation of small cell bronchogenic carcinoma of the lung and 39% incidence in extensive disease. The first trial without consolidation radiotherapy had a local failure rate of 65%, which dropped to 17% with consolidation radiotherapy to the primary and mediastinum. Prophylactic whole brain radiotherapy prevented local recurrence in 98% of evaluable patients. One carcinomatous meningitis and 5 intraspinal recurrences were noted among the 38 patients in the CAV-M trial. We conclude that high-dose vincristine sulfate is associated with an improved incidence of complete remission; that prophylactic whole brain radiotherapy has been highly successful; that prevention of intraspinal recurrence will necessitate the use of craniospinal axis radiation therapy and consolidation radiation therapy improves local control of primary and mediastinum.
