[Recent progress in chemotherapy for advanced lung cancer].
Recent progress in chemotherapy for advanced nonsmall cell lung cancer (NSCLC) and small cell lung cancer (SCLC) maybe summarized as follows. 1) In seven randomized trials of combination chemotherapy compared with best supportive care in stage IV NSCLC, meta-analysis of indicated that combination chemotherapy modestly improves survival of patients with advanced NSCLC. 2) Cisplatin-based combination chemotherapy followed by chest irradiation improves outcomes of patients with stage III unresectable NSCLC as compared with radiation therapy alone. 3) Meta-analysis has shown that survival is prolonged when radiotherapy is used in combination with chemotherapy in the treatment of limited-stage SCLC. 4) Randomized trials evaluating alternating chemotherapy could not demonstrate the survival benefit in the treatment of extensive-stage (ES) SCLC. 5) The approach to increasing dose intensity has been attempted in the treatment of ES-SCLC. The most common approach is weekly chemotherapy. Results of pilot studies have suggest that this approach prolong survival of patients with ES-SCLC. 6) Recently, several new drugs active against NSCLC and SCLC, including CPT-11, taxol, axotere, vinorelbine and gemcitabine, have been developed. In conclusion, despite these advances of treatment, the cure rate remains quite low in lung cancer. Further investigations are needed to improve the treatment results for patients with this disease.
