Induction chemotherapy with gemcitabine and cisplatin in stage III non-small cell lung cancer.
The necessity of improving the long-term survival of patients with locally advanced non-small cell lung cancer (NSCLC) points out on the one hand the limit of surgery alone and, on the other hand, the need of combined modality therapy, in which the role of chemotherapy to control distant metastases is prominent. Recent experiences support the efficacy of neoadjuvant chemotherapy with or without radiotherapy. Phase II studies show response rates of 50-80% and median survival longer than 2 years. Phase III studies suggest that neoadjuvant chemotherapy improves survival and objective responses, and induces higher percentages of complete resections compared with surgery alone or chemotherapy and radiotherapy. The gemcitabine-cisplatin regimen has proved its efficacy in NSCLC advanced disease with response rate greater than 40% in phase II and III trials. Representing one of the regimens most used in Europe, its activity has been investigated also in the neoadjuvant setting. Phase II studies have reported an average response rate greater than 60%, complete surgical resections in 60-70% of the cases, and 1-year survival of about 60%. A modern tendency is to use neoadjuvant chemotherapy in very early stages of NSCLC. Gemcitabine-cisplatin regimen has been used as a randomised clinical trial (chemotherapy for early stages trial, CHEST) to compare the efficacy of surgery alone versus surgery plus preoperative chemotherapy in early-stage disease (T2-3N0, T1-2N1, T3N1), and to evaluate the progression free survival.
