EVALUATION OF THE TREATMENT OUTCOMES OF PEMETREXED IN SECOND-LINE TREATMENT OF LUNG ADENOCARCINOMA STAGE IV
Main Article Content
Abstract
Objective: To evaluateprogression-free survival and side effects of Pemetrexed in second-line treatment of patients with lung adenocarcinoma stage IV at K hospital from January 2017 to August 2021. Methods: Combined retrospective and prospectivelongitudinal study in 33 patients with lung adenocarcinoma stage IV treated with Pemetrexed after progression on platinum-containing first-line chemotherapy. Results: Median progression-free survival was 3.4 months. There were no significant differences in median PFS between subgroups in terms of age and sex. The median PFS of patients with better performance status (ECOG) was superior compared to those with poorer ECOG (p=0.029) . Toxicity: The regimen was well tolerated. The most common toxicities were anemia, elevated transaminases, fatigue, and nausea which all at grade 1-2 toxicity. No patients experienced grade 3-4 toxicity. Conclusion: Pemetrexed is an reasonable, effective, and safe optionfor the second-line treatment of metastatic lung adenocarcinoma priorly treated with platinum-containing chemotherapy.
