Depth of Hepatic Infiltration and Lymph Node Swelling as Factors for Considering Surgery for T2-4 Gallbladder Carcinoma Patients

The aim of the present study was to clarify if the degree of hepatic infiltration and lymph node swelling of gallbladder carcinoma (GBC) should be held as deciding factors for T2-4 GBC patients to undergo surgery.Fifty consecutive patients with T2-4 GBC who underwent surgery were reviewed retrospectively. We investigated the preoperative information and imaging factors as predictors of survival.The estimated overall survival in all patients was lower in patients with hepatic infiltration ≥5 mm (n=12) than in those with <5 mm (n=38) (p=0.003). Multivariate analyses demonstrated that liver infiltration ≥5 mm (OR=2.251; 95%CI=0.906-5.596, p=0.081) and lymph node swelling (OR=2.462; 95%CI=1.034-5.859, p=0.042) were risk factors of poor survival.Our results suggested that ≥5 mm liver infiltration and lymph node swelling may serve as deciding factors for surgery consideration in GBC patients.
