Possible benefit of chemotherapy in clinical practice

Non-Small-Cell Lung Carcinoma, SURVIVAL RATEAbstract
The objective of this study was to evaluate the survival of patients with stage IV non-small cell lung cancer (NSCLC) managed according to standard clinical practice, according to the instituted treatment. All patients with stage IV NSCLC and without previous treatment assisted in the period January 1994 - July 1997 were retrospectively evaluated. 86 patients were studied, 71 males and 15 females. The median age was 61 years (range: 35-85). Thirty-four patients received chemotherapy (CT) based on a platinum salt, associated or not with radiotherapy (RT) (group 1); 26 were treated with chest RT (group 2), and 26 received exclusive symptomatic treatment (group 3). Survival analysis was performed according to the treatment performed and taking into account other variables with a possible influence on survival. The median survival time of all the patients studied was 4.5 months (95% CI: 3.0-6.5 months). The risk of dying was significantly higher for patients in group 1 compared to patients in groups 2 and 3 (Cox model, p = 0.0002). Median survival times for groups 1, 2, and 3 were 7 months versus 3.2 months versus 2 months, respectively. It is concluded that the survival of patients with stage IV NSCLC managed according to standard clinical practice is similar to that reported in prospective clinical studies, being higher in the group treated with cisplatin-based CT.
