Clinicopathological study of depth of subserosal invasion in patients with pT2 gallbladder carcinoma

Abstract

Pathological characteristics tend to become more aggressive with increasing depth of subserous carcinoma invasion in pT2 GBC. Depth of subserosal invasion is a predictor of presence and degree of lymph node metastasis in pT2 GBC. A sampling biopsy of the para-aortic nodes is recommended for inapparent pT2 GBC patients with subserosal invasion beyond one-thirds of the subserosal layer when they undergo radical second resection.
