Maintenance chemotherapy was studied in first line setting for advanced stage non-small cell lung carcinoma (NSCLC). There has not been any data on the role of continuation maintenance chemotherapy in second line setting. A retrospective cohort study that included 226 patients with advanced stage NSCLC that received second line gemcitabine +/- platinum was conducted. Patients who had continuation maintenance gemcitabine were compared with those who went on drug holiday. The primary endpoint was progression-free survival (PFS), counted from the end of induction therapy. The median PFS was significantly longer for patients who continued with maintenance gemcitabine when compared with those on drug holiday (5.6 vs 1.7 months, HR 0.392, p-value < 0.001). The overall survival was also significantly longer (21.4 vs 15.8 months, HR 0.508, p-value 0.047). There was no increase in incidence of adverse events for patients who underwent maintenance gemcitabine. Continuation maintenance therapy with gemcitabine in second line setting is a potentially feasible and safe option for patients with advanced NSCLC.
