Carboplatin plus epirubicin plus VP-16, concurrent 'split course' radiotherapy and adjuvant surgery for limited small cell lung cancer. Gruppo Oncologico Centro-Sud-Isole (GOCSI)

Thirty-three patients with limited small cell lung cancer (SCLC) received carboplatin, epirubicin and VP-16 chemotherapy, concurrent 'split course' thoracic radiotherapy, followed by surgery for patients achieving an objective response (OR). High-risk patients and those staged T4-N3 (IIIB) at diagnosis, were excluded from surgery. After induction chemoradiotherapy we obtained 90.9% OR, with 63.3% obtaining complete response (CR). Ten patients (30.3%) were eligible for surgery after induction therapy. Five patients (15.1%) were subjected to surgery and five additional patients refused. Of the five patients who were subjected to surgery, four had a complete response (CR), (three pathological confirmations), and one had a partial response (PR), (unresectable). The median survival time for all patients was 16 months with 12.1% of the long-term survivors still living after 2 years and 9% still living after 3 and 4 years. Toxicity consisted mainly of myelosuppression. This study shows a high activity of the chemotherapy and the chemoradiotherapeutic regimen employed but a low feasibility for adjuvant surgery in SCLC.
