Combination chemotherapy in the management of superior vena caval obstruction in small-cell anaplastic carcinoma of the lung

Abstract

Among 225 consecutive patients with small-cell anaplastic bronchogenic carcinoma, 26 (11.5%) had superior vena caval obstruction when the malignancy was diagnosed. Of these 26 patients, a consecutive series of 22 were treated initially with combination chemotherapy (cyclophosphamide, methotrexate and CCNU, in some cases combined with vincristine) alone, and in all these cases resolution of the syndrome was prompt within a median of 7 days. In no case were symptoms increased transiently by the treatment. No difference in response rate was observed between the histologic subtypes of small-cell anaplastic bronchogenic carcinoma according to the WHO classification. Combination chemotherapy alone is an effective treatment of superior vena caval obstruction in patients with small-cell anaplastic bronchogenic carcinoma.
