Esophageal adenocarcinoma in a first-degree relative increases risk for esophageal adenocarcinoma in patients with Barrett's esophagus.

Background: The significance of a family history of esophageal adenocarcinoma in the progression to esophageal adenocarcinoma in patients with Barrett's esophagus has not been thoroughly evaluated. The purpose of this study is to evaluate the presence of esophageal adenocarcinoma in a first-degree relative in patients with Barrett's esophagus. Methods: A retrospective cohort study was conducted of patients with Barrett's esophagus at a tertiary care center undergoing radiofrequency ablation. Family history, demographics, and pathology and endoscopy reports were assessed in all patients. Findings: Three hundred and one patients with Barrett's esophagus were assessed. Nineteen patients who had a diagnosis of esophageal adenocarcinoma on index endoscopy were excluded. Nineteen (6.7%) patients had a first-degree relative with esophageal adenocarcinoma. Four (21.1%) of these patients progressed to esophageal adenocarcinoma. Of patients without first-degree relative with esophageal adenocarcinoma 22/263 (8.7%) progressed to esophageal adenocarcinoma. In a logistic regression model adjusted for sex and the number of radiofrequency ablation treatments, we found that family history of esophageal adenocarcinoma was a significant independent predictor of progression to esophageal adenocarcinoma (odds ratio = 5.55, 95% confidence interval: 1.47-20.0). Conclusion: Our study indicates that Barrett's esophagus patients with a first-degree family member with esophageal adenocarcinoma are at 5.5-fold higher risk for disease progression to esophageal adenocarcinoma. Family history of esophageal adenocarcinoma in Barrett's esophagus patients should be considered in patient surveillance and radiofrequency ablation treatment, beyond recommended guidelines.

Long-term outcomes of palliative colonic stenting versus emergency surgery for acute proximal malignant colonic obstruction: a multicenter trial.

Background and study aims Long-term data are limited regarding clinical outcomes of self-expanding metal stents as an alternative for surgery in the treatment of acute proximal MBO. The aim of this study was to compare the long-term outcomes of stenting to surgery for palliation in patients with incurable obstructive CRC for lesions proximal to the splenic flexure. Patients and methods Retrospective multicenter cohort study of obstructing proximal CRC patients with who underwent insertion of a SEMS (n = 69) or surgery (n = 36) from 1999 to 2014. The primary endpoint was relief of obstruction. Secondary endpoints included technical success, duration of hospital stay, early and late adverse events (AEs) and survival. Results Technical success was achieved in 62/69 (89.8 %) patients in the SEMS group and in 36 /36 (100 %) patients who underwent surgery (P = 0.09). In the SEMS group, 10 patients underwent stenting as a bridge to surgery and 59 underwent stent placement for palliation. Clinical relief was achieved in 78 % of patients with stenting and in 100 % of patients who underwent surgery (P < 0.001). Patients with SEMS had significantly less acute AEs compared to the surgery group (7.2 % vs. 30.5 %, P = 0.003). Hospital mortality for the SEMS group was 0 % compared to 5.6 % in the surgery group (P = 0.11). Patients in the SEMS group had a significantly shorter median hospital stay (4 days) as compared to the surgery group (8 days) (P < 0.01). Maintenance of decompression without the recurrence of bowel obstruction until death or last follow-up was lower in the SEMS group (73.9 %) than the surgery group (97.3 %; P = 0.003). SEMS placement was associated with higher long-term complication rates compared to surgery (21 % and 11 % P = 0.27). Late SEMS AEs included occlusion (10 %), migration (5 %), and colonic ulcer (6 %). At 120 weeks, survival in the SEMS group was 5.6 % vs. 0 % in the surgery group (P = 0.8). Conclusions Technical and clinical success associated with proximal colonic obstruction are higher with surgery when compared to SEMS, but surgery is associated with longer hospital stays and more early AEs. SEMS should be considered the initial mode of therapy in patients with acute proximal MBO and surgery should be reserved for SEMS failure, as surgery involves a high morbidity and mortality.
