Clinical Report: Laparoscopic Resection Feasibility in T4 Colon Cancer
Overview
This propensity score matched study evaluated laparoscopic resection (LR) versus open resection (OR) in T4 colon cancer (CC) patients, focusing on long-term oncologic outcomes and short-term postoperative results. Findings suggest LR is a feasible and effective approach with comparable 3-year overall survival (OS) and disease-free survival (DFS) to OR, alongside favorable perioperative outcomes.
Background
Colorectal cancer is a leading cause of cancer morbidity and mortality worldwide, with T4 colon cancer representing a challenging subset due to tumor invasion and technical surgical complexity. While laparoscopic resection has demonstrated benefits in rectal cancer, its role in T4 colon cancer remains controversial due to concerns about oncologic safety and technical difficulty. Existing guidelines generally recommend open surgery for T4 lesions, except when performed by highly experienced surgeons. This study addresses the evidence gap by comparing LR and OR outcomes in T4 CC using propensity score matching.

Key Findings
Laparoscopic resection for T4 colon cancer achieves similar 3-year OS and DFS compared to open resection.
LR is associated with reduced intraoperative blood loss and shorter postoperative hospital stay.
No significant increase in major postoperative complications was observed with LR.
Complete resection rates (R0) were maintained with laparoscopic approach under experienced surgeons.
Experienced surgical teams are critical to safely perform LR in T4 colon cancer.
Clinical Implications
Laparoscopic resection can be considered a feasible and safe surgical option for selected patients with T4 colon cancer when performed by experienced surgeons. It offers perioperative advantages without compromising long-term oncologic outcomes. Careful patient selection and surgical expertise remain paramount to optimize outcomes.
Conclusion
This study supports laparoscopic resection as an effective alternative to open surgery for T4 colon cancer, providing comparable survival outcomes and improved short-term recovery metrics. These findings may inform surgical decision-making and guideline updates in managing locally advanced colon cancer.

Patients with preoperative vitamin D deficiency had higher postoperative pain scores and opioid use after mastectomy, including more than triple the odds of moderate to severe pain within 24 hours of surgery.
