Evaluation of elderly patients with extended disease small-cell lung cancer.

e18515 Background: At diagnosis approximately 25-40% of patients with small cell lung cancer (SCLC) are over age 65 and more than 60% of them have extended disease (ED). There is a scarcity of data on this subpopulation. The aim of this study was to report clinical characteristics of this subpopulation, highlighting some challenges in their clinical management. Methods: In this retrospective cohort, data from 96 patients aged >65 years with SCLC diagnosed between 1997 and 2007 at a single institution were analyzed. Results: At diagnosis median age at presentation was 71, and most patients (n=65; 67.7%) had ED_SCLC and became the focus of our analysis. In this particular population the median survival time was 5 compared to 9 months for limited disease patients. Further, 63% of these patients had performance status (PS)≥2 and that was correlated with worse survival (PS0-1=9 months, PS2=4 months and PS3-4=3months; p=0.05). Additionally, 70% of this group with ED had at least one comorbidity and 30% had more than one. Of note, chemotherapy (CT) or radiotherapy (RT) were not administered in 23% of those patients, due to the lack of clinical conditions. CT was administered in 49 patients (75%), being carboplatin and etoposide the preferred regimen in contrast to cisplatin and etoposide (71 vs 28%). However, 44% of patients received less than 4 cycles of CT and 34% received only one cycle. Number of CT cycles were correlated with survival (1 cycle 1.5 months and 2-4cycles 8.7 months). Conclusions: Our data show that elderly patients with ED-SCLC constitutes a frail subpopulation, with poor PS and associated comorbidities, leading to suboptimal treatment and a dismal prognosis. Moreover, most of those patients were considered unfit for current treatment. These results highlight the urgent need for an individualized approach and clinical trials focused on elderly patients, in order to provide them an optimal care and improve their outcomes.
