Palliative care services (PCS) have improved quality of life for patients across various cancer subtypes. Minimal data exists regarding PCSfor metastatic hepatopancreaticobiliary (HPB) and gastrointestinal (GI) cancers. We assessed the impact of PCS on emergency department visits, hospital admissions, and survival among these patients. Patients with metastatic HPB and GI cancer referred to outpatient PCS between 2014 and 2018 at a single institution were included. We compared the demographics, outcomes, and end-of-life indicators between those who did and did not receive PCS. The study included 183 patients, with 118 (64.5%) having received PCS. There were no significant differences in age, gender, race, marital status, or insurance. Those receiving PCS were more likely to have colorectal cancer (p = 0.0082) and receive chemotherapy (p = 0.0098). On multivariate analysis, PCS was associated with fewer ED visits (p = 0.0319), hospital admissions (p = 0.0002), and total inpatient hospital days (p < 0.0001) per 30 days of life. Overall survival was greater among patients receiving PCS (HR: 0.65 (0.46–0.92)). Outpatient PCS for patients with metastatic HPB and GI cancer is associated with fewer emergency department visits, hospital admissions, and inpatient hospital days, and improved overall survival.

Hepatocellular carcinoma (HCC) is a male-dominated disease. Currently, gender differences remain incompletely defined. Data from the state tumor registry were used to investigate differences in demographics, comorbidities, treatment patterns, and cancer-specific survival (HSS) among HCC patients according to gender. Additional analyses were performed to evaluate racial differences among women with HCC. 2627 patients with HCC were included; 498 (19%) were women. Women were mostly white (58%) or African American (39%)—only 3.8% were of another or unknown race. Women were older (65.1 vs. 61.3 years), more obese (33.7% vs. 24.2%), and diagnosed at an earlier stage (31.7% vs. 28.4%) than men. Women had a lower incidence of liver associated comorbidities (36.1% vs. 43%), and more often underwent liver-directed surgery (LDS; 27.5% vs. 22%). When controlling for LDS, no survival differences were observed between genders. African American women had similar HSS rates compared to white women (HR 1.14 (0.91,1.41), p = 0.239) despite having different residential and treatment geographical distributions. African American race and age >65 were predictive for worse HSS in men, but not in women. Overall, women with HCC undergo more treatment options—likely because of the earlier stage of the cancer and/or less severe underlying liver disease. However, when controlling for similar stages and treatments, HCC treatment outcomes were similar between men and women. African American race did not appear to influence outcomes among women with HCC as it did in men.

Introduction: Medicaid expansion (ME) has positively impacted colon cancer screening. ME’s effect on colon cancer treatment is less clear. This study analyses the effect of ME on patterns of colon cancer treatment. Methods: Patients with primary invasive colon cancer were identified using the Louisiana Tumor Registry. Patients diagnosed with colon cancer prior to ME (2014–2015) were compared to those diagnosed after (2017–2018). Coordinate variables were analyzed using Fisher’s exact test. Treatment status was modeled with multivariable logistic regression and the results are reported as adjusted odds ratios. Results: The proportion of uninsured patients decreased following ME (5.5 versus 1.9, p < 0.001), with the greatest reductions among patients between 45 and 54 years old (13.5% to 3.5%, p < 0.0001), African Americans (8.9 to 2.1%, p < 0.0001), and those in high-poverty neighborhoods (7.1 to 2.1%, p < 0.0001). Following ME, all patients with Stage I-III disease were more likely to receive surgery (OR = 1.95; 95%: CI 1.21–3.14)—especially the extremely impoverished (OR = 2.39; 95% CI 1.41–4.02). Young patients with Stage IV colon cancer were more likely to receive chemotherapy (OR-1.6; 95% CI 1.03–2.4). Patients with Stage IV colon cancer were less likely to receive treatment within 30 days of diagnosis (OR = 0.7; 95% CI 0.5–0.9), but, on subset analysis, this was only observed in non-Medicaid patients. Conclusion: ME is associated with increased treatment for patients with colon cancer, and it did not appear to affect time to treatment. However, it seems to affect different subsets of the population differently.

Louisiana has one of the highest incidence and mortality rates of hepatocellular carcinoma (HCC) in the nation. The aim of this study was to analyze the trends in HCC incidence and relative survival rates in Louisiana and compare them with corresponding national rates, which can be used to formulate strategies to improve Louisiana HCC outcomes. Data on primary invasive HCC diagnosed in patients 20 years or older between 2005 and 2015 were obtained from the Surveillance, Epidemiology and End Results (SEER) program and Louisiana Tumor Registry. Time trends in HCC incidence and 12-month relative survival were analyzed using Joinpoint regression. Case characteristics were compared on 2 time periods (2005–2009 and 2010–2015) using Chi-squared tests. Cause-specific survival was analyzed via log-rank and multivariable Cox proportional hazard model. Over the study period, the average annual percent change (AAPC) in age-adjusted HCC incidence in Louisiana was nearly double that of the national estimate, 6% (95% CI: 4.7, 7.3) compared to 3.1% (95% CI: 2.4, 3.7). 12-month relative survival among HCC patients in Louisiana was 40.7% (95% CI: 38.9, 42.4) which was significantly less than the US rate of 48.2% (95% CI: 47.8, 48.6). Relative survival did improve in Louisiana from 2000 to 2015 at a rate similar to that of the US (AAPC (95% CI): 2.9 (0.7, 5.2) vs. 2.7 (2.3, 3.1), p = 0.8). In multivariable survival analysis, factors amongst Louisianans associated with worse survival were older age at diagnosis, advanced stage of disease, and lack of surgical therapy. The incidence of HCC continues to rise more dramatically in Louisiana than in the US. While some modest improvements in HCC survival have been realized, outcomes remain dismal. Future work identifying the most at-risk populations are needed to inform statewide public health initiatives.
