With mortality rates of liver cancer doubling in the last 20 years, this disease is on the rise and has become the fifth most common cancer in men and the seventh most common cancer in women. Hepatocellular carcinoma (HCC) represents approximately 90% of all primary liver cancers and is a major global health concern. Patients with HCC can be managed curatively with surgical resection or with liver transplantation, if they are diagnosed at an early stage. Unfortunately, most patients with HCC present with advanced stages of the disease and have underlying liver dysfunction, which allows only 15% of patients to be eligible for curative treatment. Several different treatment modalities are available, including locoregional therapy radiofrequency ablation, microwave ablation, percutaneous ethanol injection, trans-arterial chemoembolization, transarterial radio-embolization, cryoablation, radiation therapy, stereotactic radiotherapy, systemic chemotherapy, molecularly targeted therapies, and immunotherapy. Immunotherapy has recently become a promising method for inhibiting HCC tumor progression, recurrence, and metastasis. The term “Immunotherapy” is a catch-all, encompassing a wide range of applications and targets, including HCC vaccines, adoptive cell therapy, immune checkpoint inhibitors, and use of oncolytic viruses to treat HCC. Immunotherapy in HCC is a relatively safe option for treating patients with advanced disease in the USA who are either unable to receive or failed sorafenib/lenvatinib therapy and thus may offer an additional survival benefit for these patients. The purpose of this review is to elaborate on some of the most recent advancements in immunotherapy.

Autoimmune Hepatitis is a chronic liver disease while Cardiovascular Disease is seen in inflammatory states. This study sought to determine if Cardiovascular Disease was associated with Autoimmune Hepatitis.The National Inpatient Sample selected patients with a primary diagnosis of Autoimmune Hepatitis and secondary diagnosis of Cardiovascular Disease in 2014. The primary outcome was the association of Autoimmune Hepatitis with Cardiovascular Disease. Secondary outcomes evaluated the hospital burden with Cardiovascular Disease.16,375 patients with Autoimmune Hepatitis were included in the study. There was a decreased association between Autoimmune Hepatitis and Cardiovascular Disease (aOR 0.77, 95% CI 0.69-0.85, p 0.00), Coronary Artery Disease, (aOR 0.75, 95% CI 0.67-0.85, p 0.00), and Peripheral Vascular Disease (aOR 0.75, 95% CI 0.60-0.93, p = 0.01). Moreover, Coronary Artery Disease comprises 84% of the overall Cardiovascular Disease cohort and did not demonstrate significantly increased length of stay (aOR -0.53, 95% CI -1.16 to 0.12, p = 0.11) or hospitalization cost (aOR -6711, 95% CI -14336 to 912, p = 0.08).The decreased association between Autoimmune Hepatitis and Cardiovascular Disease is likely multifactorial in etiology. Consequently, this observation requires further examination with prospective trials.

Background Postsurgical biliary disease in Roux-en-y and cholecystectomies has been investigated, but less literature exists regarding biliary complications after Whipple procedure (pancreaticoduodenectomy [PD]). Moreover, the hospital burden incurred after this complication has not been previously examined. The aim of this study is to assess the trends in hospitalization for biliary strictures and cholangitis after PD. Materials and methods The National Inpatient Sample identified all cases with a PD and a primary diagnosis of biliary complication in 2014. Cases were identified using the International Classification of Diseases, Clinical Modification codes. Primary outcomes were association of biliary complications with mortality, cost of admission, and length of stay. Results A total of 10,145 patients in 2014 were documented with a previous PD. Mortality was 50-fold greater without biliary complications (2.7% versus 0.05%), but a 95% increased length of stay (25.8 d versus 13.2 d, P = 0.014) and 70% increased cost of admission ($293,894 versus $165,862, P = 0.092) occurred with biliary complications. Regression analysis revealed increased length of stay in all cohorts (adjusted odds ratio: 14.3, P = 0.007) and increased cost of admission with cholangitis (adjusted odds: 458283, P = 0.00). Finally, there was increased biliary strictures, cost of hospitalization, and length of stay from 2011 to 2014. Conclusions Biliary disease due to the PD appears to longitudinally increase length of stay and cost of hospitalization. Compared with gastrointestinal bleed and delayed gastric emptying, biliary strictures and cholangitis are still very high acuity, requiring more extensive medical resources. Minimally invasive surgeries and robotics could play a vital role in minimizing biliary complications and the ensuing hospitalization burden.

Background and Aim Inflammatory bowel disease (IBD) and diverticulitis both increase morbidity, especially when associated with in‐patient hospitalization. This study aimed to evaluate whether hospitalization burden differs for diverticulitis in patients with a history of Crohn's disease (CD) compared to ulcerative colitis (UC). Method All patients hospitalized for acute diverticulitis with pre‐existing UC or CD in 2014 were selected using the national in‐patient sample. Cases were identified using the International Classification of Diseases, Ninth Edition codes. Primary outcomes were mortality, cost of admission, length of stay (LOS), and colectomy. Results A total of 1815 patients were admitted with diverticulitis, and those with CD had a hospitalization associated with decreased cost (aOR −14 537, 95% CI −27 316 to −1758; P = 0.026) and LOS (aOR −1.31, 95% CI −2.41 to −0.208; P = 0.02) compared to UC. A second analysis comparing diverticulitis hospitalization between those with CD and those with the absence of IBD showed no significant difference in mortality (aOR 2.47, 95% CI 0.59 to 10.36; P = 0.22), LOS (aOR 0.03, 95% CI −0.47 to 0.54; P = 0.92), or cost of admission (aOR −2196, 95% CI −6933 to 2539; P = 0.36) between the cohorts. Conclusion Patients with UC have worsened hospitalization outcomes when being treated for diverticulitis compared to CD. While the findings may be a result of a difference in colectomy rates, the etiology may also be multifactorial. These conclusions have not been previously described, and further investigations would better characterize these associations., Inflammatory bowel disease is quite prevalent, but it is unknown whether concurrent diverticulitis affects ulcerative colitis (UC) and Crohn's disease in different ways. The national in‐patient sample in 2014 demonstrated that diverticulitis with simultaneous UC resulted in increased mortality, cost of hospitalization, and length of stay compared to Crohn's disease. While colectomies may account for these findings, the cause is likely multifactorial, and these data indicate the population that may require more medical resources when hospitalized for acute diverticulitis.
