Background. There are some patients with SCLC that are diagnosed in the operating room by cryosection and surgeons had to perform surgical resection for these patients. The aim of this study is to compare the effective of pneumonectomy with lobectomy for SCLC.
Methods. A retrospective study was undertaken in 75 patients with SCLC that were diagnosed by cryosection during surgery. 31 of them underwent pneumonectomy, 44 underwent lobectomy. Local recurrence rate and survival rate according to surgical procedures and cancer stages were analyzed. Results. There was significant difference in the overall survival rate between lobectomy and pneumonectomy groups (P=0.044). For patients with stage II SCLC, the overall survival rate after pneumonectomy was significantly better than after lobectomy (P=0.028). No significant difference in overall survival rate was found between the two surgical groups in patients with stage III SCLC (P=0.933). The local recurrence rate in lobectomy group was significant higher that in pneumonectomy group (P=0.0017). Conclusions. SCLC was responsive to surgical therapy. When surgeons have to select an appropriate method of operation for patients with SCLC during surgery, pneumonectomy may be the right choice for these patients. Pneumonectomy can result in significantly better local control and higher survival rate compare with lobectomy.
