Adjuvant chemotherapy is recommended for most patients submitted to resection due to non-small cell lung cancer (NSCLC) staged as II or IIIA. However, although various chemotherapy regimens that include cisplatin have been used in phase III trials, the best choice remains unclear. The objective of this study was to describe the experience of the Instituto Nacional do Câncer (INCA, Brazilian National Cancer Institute), located in the city of Rio de Janeiro, Brazil, with the use of the cisplatin-etoposide combination in such patients, with a special focus on survival data. We retrospectively evaluated the medical charts of the patients receiving adjuvant therapy for NSCLC at the INCA between 2004 and 2008. We included 51 patients, all of whom were treated with the cisplatin-etoposide combination. The median follow-up period was 31 months, and the median overall survival was 57 months. In the univariate analysis, median survival was lower in the patients submitted to chemotherapy plus radiotherapy than in those submitted to chemotherapy alone (19 vs. 57 months; p < 0.001), and there was a trend toward lower median survival in stage III patients than in stage I-II patients (34 vs. 57 months; p = 0.22). Overall survival was not significantly associated with gender (p = 0.70), histological pattern (p = 0.33), or cisplatin dose (p = 0.13). Our results support the use of adjuvant chemotherapy, and our survival data are similar to those reported in major randomized clinical trials. However, long-term follow-up is warranted in this population.
