Barrett Esophagus-I: Introduction

96
Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more...

Summary
This summary is machine-generated.

Older age, larger tumors, advanced stage, and vascular invasion are key factors predicting poor recurrence-free survival in ampullary carcinoma. Adjuvant chemotherapy showed no significant benefit in this patient group.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Pathology

Background:

  • Carcinoma of the ampulla of Vater (CAV) exhibits variable prognoses, with some cases showing unfavorable outcomes despite generally better survival than other periampullary tumors.
  • Identifying clinicopathological factors influencing recurrence-free survival (RFS) after curative resection is crucial for risk stratification in CAV patients.

Purpose of the Study:

  • To determine clinicopathological factors associated with poor RFS in patients with CAV following curative resection.
  • To evaluate the efficacy of adjuvant chemotherapy (AC) in improving RFS for patients with CAV.

Main Methods:

  • A multicenter retrospective cohort study involving 460 patients who underwent pancreaticoduodenectomy for CAV between 2008 and 2020.
  • Evaluation of 30 clinicopathological factors and application of propensity score matching (PSM) to compare outcomes with and without AC.

Main Results:

  • Multivariate analysis identified age ≥71, tumor diameter ≥12 mm, pT stage ≥2, portal vein invasion, venous invasion, and node-positive disease as independent prognostic factors for poor RFS.
  • Adjuvant chemotherapy (AC) did not demonstrate a significant beneficial effect on RFS in the analyzed patient cohort.
  • Preoperative predictors for advanced disease (pT≥2, V+, and/or N+) included elevated CA19-9, ulcerative/mixed tumor appearance, and non-well-differentiated histology.

Conclusions:

  • Age, tumor size, pathological stage, and specific types of invasion (portal vein, venous, nodal) are critical independent prognostic factors for RFS in CAV.
  • Current adjuvant chemotherapy strategies may not be effective for improving RFS in CAV patients.
  • Further investigation into alternative or additional therapeutic strategies is warranted for high-risk CAV patients to improve outcomes.
