Abstract:
PURPOSE: It is increasingly being recognized that the lymph node ratio (LNR) is an important prognostic factor for gallbladder carcinoma patients. The present study evaluated predictors of tumor recurrence and survival in a large, mono-institutional cohort of patients who underwent surgical resection for gallbladder carcinoma, focusing specifically on the prognostic value of lymph node (LN) status and of LNR in stage IIIB patients. METHODS: Between 2004 and 2011, 123 patients who underwent R0 radical resection for gallbladder carcinoma at the Chonnam National University Hwasun Hospital were reviewed retrospectively. Patients were staged according to the American Joint Committee on Cancer 7th edition, and prognostic factors affecting disease free survival, such as age, sex, comorbidity, body mass index, presence of preoperative symptoms, perioperative blood transfusion, postoperative complications, LN dissection, tumor size, differentiation, lymph-vascular invasion, perineural invasion, T stage, presence of LN involvement, N stage, numbers of positive LNs, LNR and implementation of adjuvant chemotherapy, were statistically analyzed. RESULTS: LN status was an important prognostic factor in patients undergoing curative resection for gallbladder carcinoma. The total number of LNs examined was implicated with prognosis, especially in N0 patients. LNR was a powerful predictor of disease free survival even after controlling for competing risk factors, in curative resected gallbladder cancer patients, and especially in stage IIIB patients. CONCLUSION: LNR is confirmed as an independent prognostic factor in curative resected gallbladder cancer patients, especially in stage IIIB gallbladder carcinoma.
