BACKGROUND: The combination of radio-chemotherapy is accepted standard in limited-disease small cell lung cancer, but the best way of combining the two modalities is still unknown. To test an alternating regime of early radiotherapy with hypofractionated radiotherapy we performed a phase II study in stage III small cell lung cancer.
METHOD: 32 SCLC patients (n = 7 IIIa, n = 25 IIIb) were treated with a weekly alternating regime with either chemotherapy or radiotherapy. Chemotherapy included carboplatin (AUC5), etoposide (3 x 120 mg/m2) and vincristine (2 mg), repeated on day 28 for six cycles. Radiotherapy started one week before chemotherapy and was applied weekly 1 x 4 Gy, using a split-course regimen.
RESULTS: Combined radio-chemotherapy was well tolerated with dose-limiting hemotoxicity and very few cases of oesophagitis. Overall response was 75%, median survival 14.5 months and the 2-year survival was 34.4%. 5 patients are still living now for more than 29 months. Treatment failure was local and systemic in 34% of the patients. Systemic failure included 6 patients with brain metastases.
CONCLUSION: Combined radio-therapy in small-cell lung cancer using an alternating hypofractionated regimen is well tolerated. Response rate and 2-year survival are promising. Local and systemic failure is an ongoing problem and requires better local and systemic control of the disease.
