Abstract
Objective: Gallbladder cancer (GBC) is one of the most aggressive malignant tumors, and there is no effective and convenient method for predicting cancer-specific survival (CSS). We aim to develop a novel nomogram staging system based on the positive lymph node ratio (pLNR) for GBC patients. Methods:A total of 1,356 patients enrolled in the study. We evaluated the prognostic value of the pLNR and built a prognostic nomogram staging system based on the pLNR in the training cohort. The concordance index and calibration plots were used to evaluate model discrimination. The predictive accuracy and clinical value of the nomograms were measured by decision curve analysis (DCA). The CSS nomogram was further validated in an internal validation cohort. Results:The pLNR was an independent prognostic factor for CSS based on Cox regression analyses. A prognostic nomogram that combined T classification, pLNR, M classification, histologic grade, live metastasis, and tumor size was formulated with a c-index of 0.763 (95% CI, 0.728–0.798), while the c-indexes for the staging system of AJCC 8th, 7th, and 6th for CSS prediction were 0.718, 0.718, and 0.717, respectively. The calibration curves showed perfect agreement. The DCA showed that the nomogram provided substantial clinical value. The nomogram (the AUCs for 1, 3, and 5 years were 0.693, 0.716, and 0.726, respectively,) showed high prognostic accuracy. Conclusion:We have developed a formulated nomogram staging system based on the pLNR that allows more accurate individualized predictions of CSS for resected GBC patients than the AJCC staging systems.

Perioperative and Long-Term Outcomes of Laparoscopic Versus Open Lymphadenectomy for Biliary Tumors: A Propensity-Score-Based, Case-Matched Analysis. Ann Surg Oncol 2018; 26:564-575. [PMID: 30276646 DOI: 10.1245/s10434-018-6811-0] [Citation(s) in RCA: 40] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2018] [Indexed: 01/18/2023]
Abstract
BACKGROUND The purpose of this study was to compare patients undergoing MILS and open liver resections with associated lymphadenectomy for biliary tumors (intrahepatic cholangiocarcinoma and gallbladder cancer) in a case-matched analysis using propensity scores. METHODS A total of 104 consecutive patients underwent liver resection with associated locoregional lymphadenectomy by laparoscopic approach constituted the study group (MILS group). The MILS group was matched in a ratio of 1:2 with patients who had undergone open resection for primary biliary cancers (Open group). Short- and long-term outcomes were evaluated and compared, with specific focus on specific details of lymphadenectomy. RESULTS Laparoscopic series resulted in a statistically significant lower blood loss (200 vs. 350, p = 0.03), minor intraoperative blood transfusions (3.2% vs. 7.9%, p = 0.04), and postoperative blood transfusions (10.5% vs. 15.8%), other than shorter length of stay (4 vs. 6 days, p = 0.04). Number of retrieved nodes was 8 versus 7 (p = not significant); particularly, percentage of patients who achieved the recommended AJCC cutoff of six lymph nodes harvested were 93.7% versus 85.8% (p = 0.05). Both overall and lymphadenectomy-related morbidity (bleeding, pancreatitis, lymphatic fistula, vascular, and biliary injuries) were lower in MILS group (respectively 16.3% and 3.2% vs. 22.1% and 5.3%, p = 0.03). Median disease-free survival was 33 versus 36 months and disease recurrence occurred in 45.3% versus 55.3% of patients in MILS and Open groups respectively. CONCLUSIONS Laparoscopic approach for lymphadenectomy is a valid option in patients with biliary cancers, because it allows to maintain the advantages of minimally invasive approach, without compromising the accuracy and the outcomes of nodal dissection.
