Summary
Stage pT(1b) gallbladder cancer is typically a local disease. Radical resection is not necessary for gallbladder carcinoma invading only the muscle layer after simple cholecystectomy.
Area of Science:
- Oncology
- Surgical Oncology
- Gastroenterology
Background:
- Gallbladder cancer invading the muscle layer (stage pT1b) requires further investigation regarding its local nature.
- The necessity of radical resection for pT1b gallbladder cancer remains a clinical question.
Purpose of the Study:
- To determine if pT1b gallbladder cancer is a local disease.
- To assess the necessity of radical resection for pT1b gallbladder cancer.
Main Methods:
- Retrospective analysis of 25 patients with pT1b gallbladder tumors.
- Comparison of outcomes between simple cholecystectomy (13 patients) and radical resection with lymph node dissection (12 patients).
- Median follow-up of 95 months, with examination of 147 regional lymph nodes for metastasis.
Main Results:
- No patient exhibited blood vessel or perineural invasion; only one showed lymphatic vessel invasion.
- Absence of overt metastasis and micrometastases in all examined lymph nodes.
- Comparable outcomes and 87% 10-year survival for both simple cholecystectomy and radical resection (P=0.16).
Conclusions:
- pT1b gallbladder carcinomas are predominantly local diseases.
- Simple cholecystectomy is sufficient for gallbladder carcinoma invading only the muscle layer.
- Additional radical resection is not indicated for pT1b gallbladder cancer.
