Abstract
Objective
Gallbladder carcinoma (GBC) is one of the digestive cancers with poor prognosis, for which surgical resection is the only potentially curative therapy. Prognostic value of macroscopic inflammatory status of the resected gallbladder in patient with GBC has not been fully investigated. We retrospectively investigated the relation between macroscopic inflammatory status and disease-free as well as overall survival after radical resection for GBC.
Method
The subjects were 44 patients who underwent radical resection for GBC between January 2004 and April 2011 at Jikei University Hospital. We retrospectively investigated the relationship between clinicopathologic variables, including macroscopic inflammatory status and disease-free as well as overall survival.
Results
In univariate analysis, disease-free survival was poor in patients with Tumor-Nodes-Metastasis (TNM) stage ≥III (P < 0.0001) and positive vascular invasion (P = 0.0001). Patients with macroscopic chronic inflammation tended to have poor disease-free survival than those with normal type (P = 0.0930). Overall survival was poor in patients with TNM stage ≥III (P < 0.0001), presence of intraoperative blood transfusion (P = 0.0125), positive vascular invasion (P = 0.0055), and macroscopic chronic inflammation (P = 0.0281). In multivariate analysis, TNM stage ≥III (P < 0.0114) and macroscopic chronic inflammation (P = 0.0350) were independent predictors of disease-free survival. For overall survival, TNM stage ≥III (P = 0.0054) and macroscopic chronic inflammation (P = 0.0124) were the independent predictors. Moreover, macroscopic chronic inflammation correlated with the presence of gallstones.
Conclusion
The macroscopic Inflammation status of resected gallbladder cancer correlates with oncologic outcome in patients with GBC treated by radical resection.

Abstract
BACKGROUND Oncologic surgery for T1b-T3 gallbladder carcinoma (GBC) consists of gallbladder fossa resection or bisegmentectomy IVb/V with negative margins and portal/retropancreatic lymphadenectomy. Frequency of high quality oncologic surgery, factors associated with its use, and the ability of chemotherapy to rescue low-quality surgery (LQS) remain unknown. METHODS The NCDB was queried for patients diagnosed with stage I-III (T1b-T3) GBC undergoing curative-intent surgery from 2004 to 2016. These patients were divided into two groups based on receiving high quality surgery (HQS) or not; HQS was defined as cholecystectomy with partial hepatectomy, lymph node harvest ≥ 6, and negative margins. Logistic regression and Kaplan-Meier survival analyses were performed. RESULTS A total of 3796 patients met inclusion criteria; only 364 (9.6%) met HQS criteria, and 3432 (90.4%) did not achieve HQS and were deemed low-quality surgery (LQS). HQS was associated with improved median overall survival (55.1 vs. 25.5 months, P < .001). Adjuvant chemotherapy (AC) was not able to rescue LQS with poorer survival compared to HQS without AC (27.9 vs 55.1 months, P < .001). Factors associated with HQS included private insurance (OR 1.809, P < .001), higher income (OR 1.380, P = .038), urban/rural residence (vs metropolitan) (OR 1.641, P = .001), higher education (OR 1.342, P = .031), Medicaid expansion states (OR 1.405, P = .005), stage 3 GBC (OR 1.642, P = .020), and reresection (OR 2.685, P < .001). Factors associated with LQS included older age (OR 0.974, P < .001), comorbidities (OR 0.701, P = .004), and laparoscopic approach (0.579, P < .001). Facility type incrementally improved HQS rate (integrated cancer network vs. comprehensive community, 9.8% vs. 6.1%, OR 1.694, P = .003; academic/research center vs. integrated cancer network, 14.9% vs. 9.8%, OR 1.599, P = .003). CONCLUSION While HQS for GBC strongly improves survival, it is infrequently practiced. The newly identified factors that improve survival for GBC, such as centralization, open approach, and insurance coverage, are modifiable and, therefore, should be considered to achieve optimal outcomes.

Comparison of overall survival in gallbladder carcinoma at academic versus community cancer centers: An analysis of the National Cancer Data Base. J Surg Oncol 2020; 122:176-182.

Abstract
BACKGROUND AND OBJECTIVES Gallbladder carcinoma (GBC) has a poor prognosis. Studies demonstrated that teaching facilities may provide a lower risk of mortality in patients undergoing pancreatic and colon resection vs nonteaching facilities. We hypothesized that survival rates are higher in academic cancer centers (ACCs) vs community cancer centers (CCCs). METHODS Patients with all stages of GBC were identified from the National Cancer Database (2007-2012). Propensity score matching adjusted for selection bias. Descriptive statistics were calculated for all variables. Overall survival (OS) was compared by facility type (ACC vs CCC) and case volume (low vs high) via multivariable Cox proportional hazards regression. RESULTS A total of 7967 patients met the inclusion criteria. Following propensity matching, 2801 patients were analyzed from each facility type. Median OS following surgery was higher for ACC (20.99 months, 95% confidence interval [CI], 19.61-22.64, P = .002) than CCC (17.68 months, 95% CI, 16.46-19.25). Following Cox modeling, GBC treatment at ACCs was a protective factor for OS (adjusted hazard ratio 0.876, 95% CI, 0.801-0.958, P = .004). DISCUSSION GBC treatment at ACCs is an independent predictor of OS. High volume ACCs are associated with improved OS compared with low volume ACCs. The site of care and case volume in ACCs may contribute to improved survival outcomes.
