Abstract Disclosures


Background: Instituting platinum based chemotherapy in elderly population is often associated with poor tolerance and attending toxicities. We present our limited center experience of chemotherapy in the geriatric population group. Methods: This is a retrospective single center experience of all registered patients in lung cancer clinic (LCC) in the department of medical oncology, Dr. B.R.A. IRCH, AIIMS. All histopathologically proven cases of NSCLC with age more than 70 years who received platinum based chemotherapy (single/doublet) with complete patient records were analysed. The study was carried out between November 2016 and August 2018.Data was analysed using STATA v13. Results: The cohort consisted of 25 patients who satisfied the inclusion criteria. Males comprised 84%(n = 21) of the cohort. Median age of study population was 72.7 years years (Range 70-84). 36%(n = 9) of the study population had one comorbidity while 8% (n = 2) had multiple comorbidities. 68% (n = 17) of the cohort were smokers. ECOG(Eastern cooperative oncology group) PS (performance status) 1 was seen in 48% (n = 12) and PS 2 in 32% (n = 8) and PS 3 in 16% (n = 4) respectively of the patients. Histopathologically, 48% (n = 12) of the population constituted squamous cell carcinoma while 40%(n = 10) had adenocarcinoma. 76%(n = 19) patients had Stage 4 NSCLC. Most common chemotherapy regimes used were weekly Paclitaxel carboplatin (n = 11, 44%), three weekly paclitaxel carboplatin (n = 8 , 32%) Pemetrexed carboplatin (n = 5, 20%) and gemcitabine carboplatin (n = 1, 4%). Only 12% (n = 3) could complete more than 4 cycles of chemotherapy and 3 could receive maintenance chemotherapy. Best responses according to RECIST (Response Evaluation Criteria In Solid Tumors) criteria v1.1 achieved were complete response in 12%(n = 3), partial response in 16% (n = 4), stable disease 24%(n = 6) and progressive disease in 48%(n = 12). Most common grade 3 and 4 adverse events according to CTCAE (common terminology criteria for adverse events) v4.03 were mucositis 29.17%(n = 7), diarrhea 12% (n = 3), peripheral neuropathy 12.5 (n = 3) and hematological toxicity 16%(n = 4). Conclusions: The patient number in this study cohort is limited.However, our experience demonstrates that abbreviated therapy in elderly subgroup is fairly well tolerated. Various tools like comprehensive geriatric assessment need to be utilized to provided tailored therapy in the elderly subgroup. A prospective study is required to address the efficacy and toxicity profile of chemotherapy in this select population.
