The records of 38 patients with superior vena cava syndrome (SVC syndrome) due to malignancy and who received radiation therapy were retrospectively reviewed. The majority were lung cancers, constituting 28 of the 38 cases (73.7%). All patients were treated with conventional radiation doses ranging from 20 to 70Gy and good symptomatic response was observed in 31 cases (81.6%). The response appeared within 1.7±0.9 weeks on average (3 days-4 weeks), and performance status also improved in 50% of the patients. The median survival was 6.6 months. Long term survivors were seen mostly in patients with thymoma, and only one patient ever showed a recurrence of SVC syndrome. We conclude that radiotherapy can be an effective therapeutic modality for SVC syndrome and that it improves the quality of life in most patients.
