Pancreatic cancer is difficult to diagnose in an early stage, and has the highest mortality of all types of cancer. Obesity, high body mass index, and increased abdominal girth are established risk factors. Some studies have postulated that there is a correlation between organ steatosis and pancreatic cancer. This study aims to explore whether nonalcoholic fatty liver disease (NAFLD) is a risk factor and a prognostic factor for pancreatic cancer. The study enrolled 557 patients (143 with and 414 without pancreatic cancer) who were diagnosed between January 2009 and December 2013. We reviewed the abdominal computed tomographic scans of the patients to confirm the diagnosis of NAFLD. Clinical parameters, laboratory data, and personal information were analyzed. NAFLD is an independent risk factor for pancreatic cancer according to adjusted multivariate logistic regression analysis (OR 2.63, 95% CI 1.24-5.58, p = 0.011). The Kaplan-Meier survival curve reveals that patients without NAFLD have longer survival than patients with NAFLD (p = 0.005, log-rank test). NAFLD is positively correlated with pancreatic cancer, a result suggesting that NAFLD may increase the incidence and risk of pancreatic cancer. Patients with pancreatic cancer and NAFLD have poorer overall survival than patients without NAFLD, perhaps, because dysregulated cytokine status leads to progression of pancreatic cancer. NAFLD may be a prognostic factor for pancreatic cancer.
Myeloma-associated kidney disease (MRKD) occurs in ≤40% patients with multiple myeloma (MM). The impact of hemodialysis (HD) on patients with MM was investigated. Between 2000 and 2010, a total of 1,610 patients in Taiwan were enrolled from the National Health Institute Research Database. MM was an independent risk factor for HD following adjustment via multivariate logistic regression analysis (adjusted hazard ratio, 7.347; 95% confidence interval, 6.156-8.768; log-rank test, P<0.001). In addition, a notable decrease in survival rate was determined in patients with MM who underwent HD in the first year since diagnosis of MM. A total of 198 (61.49%) patients received HD in the first year. Patients with MM with a lower frequency of HD in the first year had a relatively good prognosis. The present study confirmed that MM was a risk factor for HD. Significant early mortality in the first year was determined in patients with MM who underwent HD; however, renal recovery following therapeutic management was a prognostic factor. In addition to anti-myeloma therapy, early initiation of HD was beneficial following risk stratification of MRKD; however, an increased probability of recovery of renal function and discontinuation of dialysis, was demonstrated in patients with MM following HD, compared with patients with MM without HD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
