Diagnostic Utility of Serum CEA and Ca 19.9 as Triage Tools for Predicting Metastatic Disease in Gallbladder Cancer: A Sub-analysis from a Prospective Observational Study.

ABSTRACT:

Purpose

Gallbladder cancer is a highly aggressive malignancy with disproportionate incidence in the Gangetic belt of India. Early diagnosis is critical yet most patients present with advanced-stage disease. Serum tumor markers like CEA and Ca 19.9 are often elevated in gallbladder cancer, but their role in rapidly triaging patients for metastatic disease at presentation has not been prospectively validated in prospective cohort.

Methods

This sub-analysis is part of a larger prospective observational study conducted at a tertiary cancer center in North India. A total of 1500 newly diagnosed, treatment-naïve or incidental gallbladder cancer patients were enrolled between September 2023 and May 2024. Serum CEA and Ca 19.9 levels were measured at baseline.
