Pattern of Care and Outcomes of Gallbladder Cancer Patients: Retrospective Study from a High Incidence Region in India.

Lakhan Kasyap Introduction  Gallbladder cancer (GBC) is the 20th most common cancer in India with a crude incidence rate of 2.3 per 100,000 persons. Of note, it is relatively common in states which fall in the Gangetic plains. Patients often present in the advanced stage and have an unfavorable prognosis. Materials and Methods  From January to June 2021, 170 treatment-naive GBC (adenocarcinoma) patients who were registered at a tertiary care cancer center in North India, were included. Data were extracted from electronic medical records and was analyzed with SPSS. Results  Median age was 56 years (range 32-77 years) and 65.5% ( n  = 112) were female. Incidental GBC was found in 20% patient ( n  = 34). Majority of patients (79.4%, n  = 135) had preserved performance status. Advanced GBC was present in 85.8% ( n  = 146) patients (locally advanced = 37.0% and metastatic = 48.8%). Biliary drainage procedure was performed in 24% of patients (68% of patients with obstructive jaundice). More than half of patients (53.5%) were lost to follow-up without any treatment. There were 33 patients (19.4%) who underwent surgery and 20 of them received neoadjuvant chemotherapy. Adjuvant chemotherapy and adjuvant radiotherapy were received by 13 and 2 patients, respectively. Palliative chemotherapy was administered to 46 patients. The most common chemotherapy regimen was gemcitabine-cisplatin. At a median follow-up of 1.7 months (95% confidence interval, 1-2.4 months), 42 patients (24%) progressed and 24 patients (14%) died, with 6 months estimated progression-free survival and overall survival being 60.2 and 79%, respectively. Conclusion  GBC is an aggressive and lethal malignancy predominantly affecting females in the fifth decade with dismal outcomes. Improved access to health care, an aggressive approach in operable cases, and optimization of systemic and adjuvant therapy are the need of the hour.
