Bariatric Surgery and Hepatocellular Carcinoma: a Propensity Score-Matched Analysis.

ABSTRACT: BACKGROUND:The association between obesity and rising incidence of hepatocellular carcinoma (HCC) in the USA has been documented; however, the role of bariatric surgery remains less clear. AIM:To evaluate the cross-sectional association of prior-bariatric surgery and HCC. METHODS:The United States Nationwide Inpatient Sample (NIS) database was queried from 2004 to 2014 for discharges with a diagnosis of morbid obesity. Primary outcomes of interest were HCC and in-hospital mortality rate. Secondary outcomes were length of stay and cost. Baseline characteristics were balanced using propensity score matching (PSM). Using Poisson and logistic regressions, adjusted HCC prevalence ratio (PR) and mortality odds ratio (OR) were derived in patients with prior-bariatric surgery compared to those without bariatric surgery. RESULTS:Of the 2,881,414 patients included in our study, 267,082 (9.3%) underwent bariatric surgery. From 2004 to 2014, there was a threefold increase in age-adjusted prevalence of HCC from 27 per 100,000 to 72 per 100,000 (PTrend < 0.001). After PSM, 230,956 patients with prior-bariatric surgery were matched with 230,956 patients without bariatric surgery. Prior-bariatric surgery was associated with lower prevalence of HCC (PR 0.11; 95% CI, 0.03-0.48; P?

Project description:Purpose:To investigate whether juvenile patients with nasopharyngeal carcinoma (NPC) in China have better prognosis than their adult counterparts in the intensity-modulated radiation therapy (IMRT) era, after controlling for potential confounding variables. Methods:Data pertaining to 1139 patients with newly diagnosed NPC without metastasis, who were treated with IMRT at our hospital, were retrospectively analyzed. Of these, 60 patients were juvenile (age ?18 years) diagnosed between January 2003 and December 2018, while 1079 patients were adults (?65 years) diagnosed between January 2013 and December 2014. To minimize the influence of selection and confounding bias, 1:2 propensity score matching (PSM) was used. Overall survival (OS), disease-free survival (DFS), locoregional relapse-free survival (LRFS), and distant metastasis-free survival (DMFS) were estimated using the Kaplan-Meier method and between-group differences assessed using the Log rank test. The long-term toxicity of the juvenile patients was evaluated according to the criteria of the Radiation Therapy Oncology Group (RTOG) and the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. Results:Five-year OS of juvenile and adult patients were 88.07% and 85.08%, respectively. Before PSM, OS, PFS, DMFS, or LRFS were comparable in the two groups (all P > 0.05). After PSM, OS, DFS, and LRFS in the juvenile group were markedly longer than that in adults (P = 0.005, P = 0.027, and P = 0.024, respectively). With respect to long-term toxicity, the most common adverse effects in juvenile patients were cervix fibrosis, ototoxicity, and xerostomia. However, except for two patients who developed grade 3 ototoxicity, all adverse effects were within grade 2. Conclusion:In the IMRT era, juvenile Chinese patients with NPC had better 5-year OS, DFS, and LRFS than their adult counterparts. The adverse events in the juvenile cohort were relatively mild; however, the risk of severe ototoxicity should not be neglected.
