Abstract

Background: Non-small cell lung cancer (NSCLC) is the most common type of malignant lung tumor and usually diagnosed in patients aged ≥65 years. Chemotherapy is the standard of care for advanced stage in fit patients. Those who accepted palliative treatment get poor survivorship.


Objective: To determine the efficacy, tolerability and side effects of the first-line regimen for treating advanced NSCLC in the elderly patients, and to compare the survival between chemotherapy and supportive treatment.


Material and method: A retrospective cohort study was conducted among the patients aged ≥60 years diagnosed with advanced NSCLC at Lampang Hospital between 1 January 2017 and 30 April 2020. The chemotherapy group received first-line (platinum-based) regimen. Clinical data included the Eastern Cooperative Oncology Group performance status (ECOG PS), response rate, number of cycles and median overall survival. Data were compared between
chemotherapy and supportive care group. Factors related with survival were analyzed using Cox regression analysis.


Results: 90 patients were enrolled, 55 received chemotherapy (61.1%) and 35 received supportive care (38.9%). 76% of patients in chemotherapy group had ECOG PS 1 and 31.4% in supportive care group had ECOG PS 3–4 (p<0.001). The average course was 4 cycles (range 1–6) and 28 cases (51%) completed the 6th cycle. The overall response rate was 21.8% and the clinical benefit rate was 58.2%. Twenty-one patients received the second-line regimen and
nine received the third-line regimen. The most common side effects were anemia (40%) and asthenia (33%). The median progression free survival of the first-line chemotherapy was 140 days. The median overall survival was 256 days in chemotherapy group and 49 days in BSC group. Chemotherapy was associated with 63% reduction the hazard of death (HR 0.37, 95%CI
0.23–0.57, p<0.001). Factors related with decreased and increased mortality were serum albumin >3.5 g/dl (HR 0.45, 95%CI 0.22–0.92, p=0.030) and male (HR 2.43, 95%CI 1.10–5.35, p=0.028) respectively.


Conclusions: Chemotherapy provided better survival than supportive care among elderly patients with advanced NSCLC. The first-line regimen had good response rate and acceptable side effects.
