    Abstract Aims: Abnormal p53 protein expression detected by immunohistochemistry (IHC) in Barrett's oesophagus (BO) is reported to be a prognostic biomarker for progression to high-grade dysplasia (HGD) or oesophageal adenocarcinoma (OAC). We evaluated our use of p53 IHC for patients with BO under surveillance from 2010 to 2016 in a single academic institution.
    Methods and results: We identified 78 patients under surveillance for BO who had biopsies evaluated for abnormal p53 expression in conjunction with routine histology and 892 patients who had histological evaluation alone. All available p53 IHC slides were rescored as wild-type or abnormal. We evaluated the risk of subsequent diagnosis with HGD and OAC. p53-tested patients were significantly more likely to be diagnosed with indefinite dysplasia (IND) or low-grade dysplasia (LGD), compared to patients who were not tested (79.5 versus 10.8%, P = 7.4 × 10
    Conclusion: In patients under surveillance for BO in a single academic institution, we found evidence that selective use of p53 IHC in conjunction with routine histology modestly improved risk stratification by identifying patients with IND at higher risk of a subsequent diagnosis of HGD or OAC.

    Abstract The optimal management of intramucosal carcinoma in Barrett's esophagus continues to be controversial. To date, there has not been a lot of research directly comparing endoscopic versus surgical management of intramucosal carcinoma. Previous studies have shown that both modalities to have excellent outcomes. The reviewed article is a matched retrospective cohort study from two high-volume centers, which shows both modalities to be effective, but an associated higher morbidity rate and risk for procedure-related mortality in the surgical group, and higher recurrence rate in the endoscopic therapy group. The study is discussed in the context of the current state of knowledge regarding Barrett's esophagus and intramucosal carcinoma, in particular outcomes and limitations of the present study.

    Abstract Advances in the development of endoscopic therapies for Barrett's esophagus have resulted in the emergence of an important paradigm shift for management of early neoplasia and represent an opportunity to alter the natural history of the disease. Clinical incorporation of these endoscopic modalities may have significant implications for disease management and health care delivery from a cost perspective. This article reviews the current literature on the cost analyses of commonly used Barrett endoscopic interventions and summarizes the overall cost-effectiveness of these treatments as compared with surveillance or surgery.

    Abstract The annual incidence of adenocarcinoma arising from Barrett’s esophagus (BE) is approximately 0.5%. Through a process of gradual transformation from low-grade dysplasia to high-grade dysplasia (HGD), adenocarcinoma can develop in the setting of BE. The clinical importance of appropriate identification and treatment of BE in its various stages, from intestinal metaplasia to intramucosal carcinoma (IMC) hinges on the dramatically different prognostic status between early neoplasia and more advanced stages. Once a patient has symptoms of adenocarcinoma, there is usually locally advanced disease with an approximate 5-year survival rate of about 20%. Esophagectomy has been the gold standard treatment for BE with HGD, due to the suspected risk of harboring occult invasive carcinoma, which was traditionally estimated to be as high as 40%. In recent years, the paradigm of BE early neoplasia management has recently evolved, and endoscopic therapies (endoscopic mucosal resection, radiofrequency ablation, and cryotherapy) have entered the clinical forefront as acceptable non-surgical alternatives for HGD and IMC. The goal of endoscopic therapy for HGD or IMC is to ablate all BE epithelium (both dysplastic and non-dysplastic) due to risk of synchronous/metachronous lesion development in the remaining BE segment.
