Postoperative chemotherapy for non-small-cell lung cancer.
The Lung Cancer Study Group has performed a number of postoperative adjuvant trials in patients with resectable non-small-cell lung cancer (NSCLC). Adjuvant cyclophosphamide, doxorubicin, and cisplatin (CAP) chemotherapy was compared with immunotherapy in the treatment of 130 patients with stage II or III adenocarcinoma or large cell undifferentiated carcinoma. Careful intraoperative staging was performed in all patients. Disease-free interval was significantly prolonged in the chemotherapy group (p = 0.032). After 7.5 years of follow-up, the difference in time to recurrence and cancer deaths remains statistically significant. Another study compared CAP chemotherapy plus radiotherapy with radiotherapy alone in advanced stages II and III resected NSCLC. Again, the chemotherapy arm had significantly increased disease-free survival. In a third study, patients with high-risk stage I NSCLC were randomized after surgery to CAP chemotherapy or observation. In this study there was no difference in recurrence-free survival or overall survival.
