Background/Aims: Endoscopic resection has become the preferred treatment approach for select early esophageal adenocarcinoma (EAC); however, the epidemiology of early stage disease has not been well defined. Methods: Surveillance Epidemiology and End Results (SEER) data were analyzed to determine age-adjusted incidence rates among major epithelial carcinomas, including EAC, from 1973 to 2017. The percent change in incidence over time was compared according to tumor subtype. Early T-stage, node-negative EAC without metastasis was examined from 2004 to 2017 when precise T-stage data were available. Results: The percent change in annual incidence from 1973 to 2017 was 767% for EAC. Joinpoint analysis showed that the average annual percent change in EAC from 1973 to 2017 was 5.11% (95% confidence interval 4.66, 5.56). The annual percent change appeared to plateau between 2004 and 2017; however, early EAC decreased from 2010 to 2017, with an annual percent change of -5.78%. Conclusions: There has been a 7-fold increase in the incidence of EAC, which was significantly greater than that of the other major epithelial malignancies examined. More recently, the incidence of early EAC has been decreasing. Approximately one in five patients has node negative, potentially resectable early stage disease. Clin Endosc 2022 Feb 11.

Hepatocellular carcinoma (HCC) is the fourth most common cause of cancer related mortality worldwide, with the most common underlying etiologies being chronic hepatitis B and hepatitis C infections.Treatment of these viral hepatidities in the setting of HCC has been debated, and there is increasing study addressing this topic. Patients with advanced HCC of either etiology are unlikely to benefit from antiviral treatments, and futility should be considered prior to starting antiviral therapy. Hepatitis B treatment has demonstrated improved survival, decreased risk of hepatitis B reactivation, and decreased risk of late HCC recurrence. The mainstay treatment of chronic hepatitis B has been nucleos(t)ide analogues (NAs), and in the setting of HCC, entecavir and tenofovir are preferred given their higher potency and barriers to resistance.Those who were already on a NAs at the time of HCC diagnosis should be continued on them regardless of the HCC management planned. Patients who are suitable candidates to start NAs should start them at the time of HCC diagnosis. Direct-acting antivirals (DAAs) are the first line therapies for hepatitis C. Unlike with hepatitis B, those with HCV-associated HCC are recommended to start treatment 3-6 months after complete treatment of their HCC, given lower rates of sustained virologic response (SVR) with active HCC.There are also controversial concerns about DAAs contributing to a more aggressive HCC phenotype, but data are limited by retrospective studies, and more recent retrospective studies are more reassuring. In transplant candidates, starting DAAs may be deferred until after transplant depending on median regional wait times, availability of HCV positive organs, and the degree of the patient's liver dysfunction. Overall, in patients with HCC from hepatitis B or C, treatment of the underlying viral hepatitis should be considered unless advanced stage limits benefits and results in futility.
