CPC-017 Analysis of Survival in Patients with Advanced Non-Small Cell Lung Cancer

Background Non-small cell lung cancer (NSCLC) accounts for most cases of lung cancer. Approximately 40% of patients with NSCLC present with advanced-stage disease at the time of diagnosis. Purpose To analyse the median overall survival in patients with NSCLC stage IIIB or IV. Materials and Methods Retrospective observational study. Patients with NSCLC stage IIIB or IV who started treatment between 01/01/2011 and 30/06/2011. Data source: Patient medical records, oncology programme (Oncowin) and outpatient dispensing record programme (SAVAC and Farmatools). Data recorded: age, gender, age at diagnosis, stage, histology, chemotherapy, number of chemotherapy cycles and number of prior chemotherapy regimens. Results Thirty patients were included with a median age at diagnosis of 63 years (IC95% 60–66). 73.3% were male. The stage at time of diagnosis was IV in 80% of patients. The most common histology was adenocarcinoma (50%), 30% squamous cell carcinoma, 10% large cell and another 10% other histological type. Platinum-based chemotherapy was the first line treatment in 66.7% of the patients and for the remaining 23.3% it was vinorelbine alone or in combination. Six patients received maintenance treatment, three with erlotinib, two with pemetrexed and one with bevacizumab. The median progression-free survival time was 4 months (IC95% 2.9–5.1) in patients receiving maintenance treatment and 3 months (IC95% 0.8–5.2) in patients who were not given maintenance treatment. The median overall survival time was 6 months (IC95% 1.2–10.8) for patients with maintenance treatment and also 6 months (IC95% 3.1–8.8) in patients without maintenance treatment. Conclusions Platinum-based chemotherapy remains the standard treatment. According to the latest guidelines issued by ESMO the role of maintenance is not yet defined. In our study only a few patients were candidates for this treatment. The median overall survival time found in our study was similar in the two groups. No conflict of interest.
