# Surgical Timing and Outcomes in Esophageal Cancer: Insights from One- and Two-Stage Esophagectomies in a Polish Cohort

## TL;DR

This study examines postoperative complications in esophageal cancer patients who underwent one- or two-stage esophagectomies, finding that advanced disease and preoperative therapy increase risks.

## Contribution

The study identifies specific predictors of complications in esophageal cancer surgery, particularly the impact of neoadjuvant chemoradiotherapy.

## Key findings

- Postoperative complications occurred in 24.6% of patients, with pneumonia, anastomotic leakage, and hemothorax being most common.
- Neoadjuvant chemoradiotherapy significantly increased complication risk, with an odds ratio of 8.75.
- Anastomotic leakage rates were similar between one- and two-stage procedures.

## Abstract

Objectives: Esophagectomy is a central component of surgical treatment for esophageal cancer, with both one- and two-stage procedures frequently employed. However, these procedures are associated with a high rate of postoperative complications. This study aimed to assess the rates and types of complications following one- and two-stage esophagectomies, and to identify predictors of adverse outcomes in patients with esophageal cancer. Methods: We analyzed clinical data from patients undergoing one-stage (Ivor Lewis) or two-stage esophagectomies. Postoperative complications were defined as events occurring within 30 days after surgery. Variables such as patient demographics, clinical staging, histological tumor grade, and neoadjuvant chemoradiotherapy were assessed for their association with complications. Statistical analyses included logistic regression and chi-squared tests. Results: Among 61 patients, postoperative complications occurred in 24.6% of cases. The most frequent were pneumonia (22.2%), anastomotic leakage (22.2%), and hemothorax (27.8%). Significant predictors of complications included intraoperative disease staging, histological tumor grade, and the use of neoadjuvant chemoradiotherapy. The odds ratio for complications following neoadjuvant chemoradiotherapy was 8.75. The frequency of anastomotic leakage was similar in one- and two-stage procedures (30.8% vs. 26.3%, respectively). Conclusions: Postoperative complications remain a significant challenge in esophageal cancer surgery, particularly in the context of advanced disease or neoadjuvant chemoradiotherapy. These findings underscore the necessity for precise surgical planning and comprehensive postoperative care to mitigate risks and optimize patient outcomes. While postoperative risk is high, it is primarily driven by tumor characteristics and preoperative therapy.
