Pancreatic metastases: An increasing clinical entity

Area of Science:

• Oncology
• Surgical Oncology
• Gastroenterology

Background:

• Pancreatic metastases are uncommon but increasingly recognized, particularly at high-volume centers.
• Often asymptomatic, they are detected incidentally or during surveillance years post-primary tumor resection.
• Renal cell cancer is the most frequent primary source, followed by colorectal cancer, melanoma, sarcoma, and lung cancer.

Purpose of the Study:

• To review the diagnosis, indications for surgery, and outcomes of pancreatic metastasectomy.
• To highlight the importance of surgical resection for isolated, resectable pancreatic metastases.
• To discuss factors influencing outcomes, emphasizing primary tumor biology.

Main Methods:

• Review of literature on pancreatic metastases and metastasectomy.
• Analysis of surgical strategies including standard and atypical resections.
• Evaluation of prognostic factors and survival rates based on primary cancer type.

Main Results:

• Pancreatic metastasectomy is indicated for resectable, isolated metastases in fit patients.
• Resection strategies prioritize adequate margins and pancreatic tissue preservation.
• Renal cell cancer metastases have the best prognosis, with >70% 5-year survival post-resection.

Conclusions:

• Pancreatic metastasectomy is a viable option for selected patients with pancreatic metastases.
• Patient selection and surgical technique are crucial for successful outcomes.
• Tumor biology, especially from renal cell carcinoma, significantly impacts long-term survival.
