BACKGROUND: Incidental gallbladder cancer (iGBC) is on the rise world over. This may be a good scenario as we get to treat GBC in early stages. However, there is a practice of diagnosing patients based on clinicoradiological findings alone and subjecting them to a radical surgical procedure. This approach over-treats patient and has important implications for resource utilization. METHODS: We performed a retrospective analysis of 284 consecutive patients undergoing upfront surgery for suspected GBC from January 2010 to December 2016. The study cohort was divided into two groups, group A – benign (n = 138, 48.6%) and group B – malignant (n = 146, 51.4%). Both groups were compared with respect to demographic characteristics, tumor marker levels, clinicoradiological features, and perioperative outcomes. RESULTS: Approximately 48.6% patients with clinicoradiological suspicion of GBC turned out to be benign on final histology as confirmed on frozen section evaluation (FS). Only 2 patients who were reported benign on FS required revision surgery for malignancy in the final histopathology report. Demographic and clinicoradiological characteristics in both groups were comparable. However, there was a significant difference in blood loss, postoperative hospital stay, and complications between the two groups (P < 0.005). CONCLUSION: Every other patient who presented to a tertiary cancer center with high index suspicion for malignancy, based on clinicoradiological findings, turned out to be benign on final histology. This emphasizes the fact that, as a norm, for radiologically suspected gallbladder malignancy, we need to have a confirmed histological diagnosis at least during surgery before proceeding to radical resection.
