Summary

This summary is machine-generated.

Ampulla of Vater carcinoma (AVC) recurrence is often linked to lymph node metastasis, particularly to the pancreatic head region. This finding is crucial for predicting relapse-free survival in AVC patients post-surgery.

Area Of Science

  • Oncology
  • Surgical Gastroenterology
  • Pathology

Background

  • Ampulla of Vater carcinoma (AVC) is rare, leading to limited understanding of its clinicopathologic variables and outcomes.
  • Postoperative outcomes and prognostic factors for AVC require further elucidation.

Purpose Of The Study

  • To investigate clinicopathologic variables and postoperative outcomes in patients with AVC.
  • To identify prognostic indicators for relapse-free survival in AVC patients.

Main Methods

  • Retrospective review of clinical records for patients who underwent surgical exploration for AVC.
  • Univariate and multivariate analyses were employed to assess outcomes and identify predictors.

Main Results

  • One-, three-, and five-year survival rates were 97.4%, 71.8%, and 63.0%, respectively.
  • Common recurrence sites included lymph nodes (52%), liver (38%), and lung (29%).
  • Multivariate analysis identified lymph node metastasis to the pancreatic head region as a predictor of inferior relapse-free survival.

Conclusions

  • Lymph node metastasis, especially to the pancreatic head region, is a significant prognostic indicator for reduced relapse-free survival in AVC.
  • Pathological lymph node metastasis strongly correlates with postoperative recurrence in AVC.
