Surgery in the management of small cell lung cancer

Objective:
We analyzed our experience in the period January 1975-December 1995 aiming to confirm the role of surgery in the multimodality treatment of small cell lung cancer (SCLC).
Methods:
127 patients (5.28% of the overall lung resections for carcinoma) underwent surgery for SCLC. The median age was 60 years (range 34-73). In 87 patients (68.5%) a pre-operative tissue diagnosis was effected and those patients underwent a complete staging procedure. Fifteen patients received up to six complete courses of neoadjuvant and adjuvant chemotherapy. The surgical procedures included: 50 pneumonectomies, 71 lobectomies and six wedge resections. Two patients experienced a local recurrence and a completion pneumonectomy was performed.
Results:
The median follow-up is 66 months (range 6-214). The 5-year actuarial survival rate is 22.6% (median 18 months). Twenty-three patients are still alive, 21 of them being disease-free. Considering the most conspicuous group of patients (n = 92) treated by surgery and adjuvant chemotherapy, the survival data were 47.2, 14.8 and 14.4% for Stage I, II and III, respectively (P = 0.001). NO patients had a significantly better survival than N1 and N2 patients (P = 0.035).
Conclusions:
Surgery and adjuvant chemotherapy might represent an effective form of treatment of limited SCLC without lymph-node involvement. The role of surgery is yet to be verified as regards N1 and N2 status, where even neoadjuvant chemotherapy has not achieved the hoped-for results (no patient reaching a 2-year survival).
