Duration of chemotherapy for locally advanced non small cell lung cancers]. PG - 16S72-16S77 AB - BACKGROUND: Optimal duration of first line chemotherapy for non surgical non small cell lung cancer (NSCLC) is still debated. It concerns the length of initial chemotherapy and the use of maintenance treatments. METHODS: Literature review was performed on maintenance and duration of chemotherapy. RESULTS: The use of maintenance chemotherapy showed no differences in terms of survival. One study (with gemcitabine as maintenance treatment) found a difference in terms of time to progression. Several randomized clinical trials were carried out on duration of chemotherapy. There were no impact on survival time. CONCLUSION: No positive results were found with an increase of chemotherapeutic cycles. Maintenance therapy needs more additive studies. ASCO guidelines may be currently used.
