The Impact

Management of columnar lined oesophagus (CLO; Barrett s oesophagus) is controversial. We prospectively audited surveillance practices in Scotland and prospectively assessed the impact of introducing local guidelines for Barrett s surveillance in Edinburgh. Most respondents were gastroenterologists. The majority take random, not four quadrant, biopsies from the CLO. In Edinburgh during 2000, 80 patients underwent surveillance. The guideline protocol was not followed in 30 (37.5%) patients. Follow up of patients without dysplasia generally conformed to the guidelines. Follow up of patients with low grade dysplasia was highly variable while management of those with high grade dysplasia followed the guidelines. Overall we found a wide variability in the management and surveillance of CLO. Early experience suggests that implementation of guidelines is helpful but there is still variation in practice.

SUMMARY Patients with Barrett's esophagus (BE) and low-grade dysplasia (LGD) are at increased risk of esophageal adenocarcinoma (EAC), although many regress to nondysplastic BE. This has significant clinical importance for patients being considered for endoscopic eradication therapy. Our aim is to determine the risk for progression in patients with confirmed persistent LGD. We performed a single-center retrospective cohort study of patients with BE and confirmed LGD between 2006 and 2016. Confirmed LGD was defined as LGD diagnosed by consensus conference with an expert GI pathologist or review by an expert GI pathologist and persistence as LGD present on subsequent endoscopic biopsy. The primary outcome was the incidence rate of HGD (high-grade dysplasia)/EAC. Secondary outcomes included risk factors for dysplastic progression. Risk factors for progression were assessed using univariate and multivariate analysis with logistic regression. Of 69 patients (mean age 65.2 years) with confirmed LGD were included. In total, 16 of 69 patients (23.2%) with LGD developed HGD/EAC during a median follow-up of 3.74 years (IQR, 1.24–5.45). For persistent confirmed LGD, the rate was 6.44 (95% confidence interval (CI), 2.61–13.40) compared to 2.61 cases per 100 patient-years (95% CI, 0.83–6.30) for nonpersistent LGD. Persistent LGD was found in only 29% of patients. Persistent LGD was an independent risk factor for the development of HGD/EAC (OR 4.18; [95% CI, 1.03–17.1]). Persistent confirmed LGD, present in only 1/3 of patients, was an independent risk factor for the development of HGD/EAC. Persistence LGD may be useful in decision making regarding the management of BE.

Early Stage Disease

20 Background: Esophageal adenocarcinoma (EAC) incidence is rising and prognosis is uniformly poor, even with early stage disease. Barrett esophagus (BE) serves as a premalignant marker for EAC, with an estimated progression of 0.5% per year. Low-grade (LGD) and high-grade dysplasia (HGD) confer a higher risk of progression, providing an opportunity for intervention and surveillance. Aims: To evaluate a large cohort of patients undergoing endoscopic evaluation of BE and thereby better understand the natural history of BE and dysplasia. Methods: A retrospective review of endoscopic databases was conducted for all patients with the diagnosis of BE undergoing upper endoscopy at a tertiary academic medical center from 1991-2010. All endoscopy and accompanying pathology reports were reviewed. Only those patients with 2 biopsies documenting specialized intestinal metaplasia were analyzed. Results: 848 patients underwent upper endoscopy for evaluation of BE. Of these, 674 patients met inclusion criteria, at a mean follow up of 66.6 months. Table 1 depicts the distribution of patients according to their histology at presentation. 22 (3.2%) patients presented with established EAC, while EAC developed in 51 (7.6%). Of patients with HGD, LGD, or no dysplasia (ND) at presentation, EAC ultimately developed in 30.6%, 6.6%, and 2.7%, respectively. EAC developed in 4 patients despite RFA treatment for ND (2) or LGD (2). HGD developed in 6 such patients after treatment for ND (3) and LGD (3). Only 1 patient in each RFA-treated cohort required esophagectomy, while the others cleared dysplasia or EAC with continuous treatment. Conclusions: In this large cohort of patients with Barrett’s esophagus, higher grade of dysplasia at first endoscopy was associated with development of EAC. Continuous surveillance during and after endoscopic treatment is necessary and often results in clearance of dysplasia and EAC. [Table: see text]

Introduction. Despite a significant number of publications and a concept known as Correa’s cascade, dysplas-tic processes and the mechanisms of gastric carcinogenesis, are still far from being completely understood. Dysplasia and the processes in the mucous membrane adjacent to the tumor node, their significance, and their role in the field cancerization have also been studied insufficiently. The aim of this work was to analyze the frequency of occurrence and some characteristics of high- and low-grade dysplasia in the gastric mucosa at variable distances from the tumor node. Materials and methods. We carried out a prospective histological study of surgical specimens from 49 patients with intestinal type gastric adenocarcinoma. We studied tissues from the tumor node and adjacent gastric mucosa at various distances from the tumor and assessed the frequency of occurrence and some characteristics of low- and high-grade dysplasia. Results. In the mucous membrane adjacent to the intestinal type adenocarcinoma, 73.5% of cases demon-strated low- and high-grade dysplasia. In all cases, background and precancerous processes were found in areas adjacent to the tumor node with low- and high-grade dysplasia. Conclusion. The incidence of low- and high-grade dysplasia detected in the mucous membrane adjacent to intestinal type gastric adenocarcinoma significantly decreases as the distance from the tumor node in-creases. Dysplastic changes are associated with epithelial hyperplasia, intestinal metaplasia, and inflamma-tory and atrophic changes. The results obtained support field cancerization and highlight the need to study morphological, molecular, and genetic alterations in the gastric mucosa adjacent to the tumor more deeply. The dysplastic changes present at the resection line area indicate that this fact must be considered when determining the resection line.

The Impact

This chapter discusses screening for gastrointestinal disease, including Barrett’s oesophagus (BO), colorectal cancer, and hepatocellular cancer (HCC). In patients with BO, approximately 5% will develop dysplasia, and 10%–50% of the low-grade dysplasias will progress to high-grade dysplasia or adenocarcinoma within 2–5 years. Thus, screening for BO has been developed to reduce the development of adenocarcinoma via the early detection of high-grade dysplasia or cancer in situ. The main aim of colorectal cancer screening is the early detection of polyps and cancers, at a time when treatment is likely to be more effective. Similarly, early detection of HCC is advantageous, as the prognosis in advanced disease is very poor. This chapter describes the current processes of screening for these diseases, and the impact of this screening, as well as screening for gastrointestinal cancer in specific groups.

Abstract Object The aim of this study is to investigate the impact of surgery for different cervicomedullary lesions on symptomatic pattern expression and postoperative outcome. We focused on specific outcome features of the early and late postoperative assessments. The former relies on surgery-related transient and permanent morbidity and feasibility of radicality in eloquent areas, whereas the latter on long-term course in lower grade tumors and benign tumorlike lesions (cavernomas, etc.). Material and Methods We retrospectively analyzed 28 cases of intramedullary tumors of the cervicomedullary junction surgically treated at our institution between 1990 and 2018. All cases were stratified for gender, histology, macroscopic appearance, location, surgical approach, and presence of a plane of dissection (POD). Mean follow-up was 5.6 years and it was performed via periodic magnetic resonance imaging (MRI) and functional assessments (Karnofsky Performance Scale [KPS] and modified McCormick [MC] grading system). Results In all, 78.5% were low-grade tumors (or benign lesions) and 21.5% were high-grade tumors. Sixty-one percent underwent median suboccipital approach, 18% a posterolateral approach, and 21% a posterior cervical approach. Gross total resection was achieved in 54% of cases, near-total resection (>90%) in 14%, and subtotal resection (50–90%) in 32% of cases. Early postoperative morbidity was 25%, but late functional evaluation in 79% of the patients showed KPS > 70 and MC grade I; only 21% of cases showed KPS < 70 and MC grades II and III at late follow-up. Mean overall survival was 7 years in low-grade tumors or cavernomas and 11.7 months in high-grade tumors. Progression-free survival at the end of follow-up was 71% (evaluated mainly on low-grade tumors). Conclusions The surgical goal should be to achieve maximal cytoreduction and minimal postoperative neurologic damage. Functional outcome is influenced by the presence of a POD, radicality, histology, preoperative status, and employment of advanced neuroimaging planning and intraoperative monitoring.
