Gallbladder Cancer

Gallbladder cancer is categorized into various types: (i) Infiltrative, (ii) Nodular, (iii) Nodular-infiltrative, (iv) Papillary, and (v) Papillary-infiltrative. CECT findings in GBC include the GB lumen filled with a mass (42%), a mass replacing the GB (26%), a polypoid mass (26%), and diffuse wall thickening (6%). Simple cholecystectomy is curative in 90% of T1a tumors. Radical cholecystectomy is recommended for T1b and T2 tumors. En bloc adjacent organ resection may have to be performed with radical cholecystectomy for T3 and T4 tumors, though the prognosis may not be good.
