The Value and Yield of Continued Cancer Surveillance of a Surgical HPB Oncology Practice

Abstract

Introduction

Due to rising incidence of Hepato-Pancreato-Biliary (HPB) malignancies and more effective therapies, there are increased survivors after curative surgery but little emphasis is placed on survivorship. This study aims to evaluate the value and yield of postoperative surveillance of surgically treated HPB cancer patients within a single surgeon’s practice.

Methods

A retrospective 1-year (2024) review identified 128 unique patients with prior surgical resection of a HPB malignancy undergoing active cancer surveillance by the surgical team. We excluded patients with benign indications for surgery or active cancer surveillance outside of the surgical team.

Results

Of these, 112 (87.5%) and 16 (12.5%) underwent pancreatic and hepatobiliary resection, respectively. Median follow up was 1.5 years from the index operation (IQR: 0.7-2.8 years). Pancreatic pathology was pancreatic adenocarcinoma (PDAC), neuroendocrine, or miscellaneous in 70, 25, and 9 patients, respectively. Hepatobiliary pathology was cholangiocarcinoma (CCA), metastatic colorectal cancer, or hepatocellular carcinoma in 16, 6, and 2 patients, respectively. We identified 12 (9.3%) patients who had findings during the study time period resulting in a repeat HPB surgery. In addition, we identified 12 (9.3%) patients who required referral to another department for additional medical, surgical, or interventional treatments. The remaining 104 (81.2%) patients had findings of either no disease recurrence or stable disease with continued surveillance as a recommendation.

Conclusion

This study underscores the value of cancer surveillance for HPB cancer patients, demonstrating a yield of nearly 20% of patients with findings requiring repeat surgical intervention or referral to other departments.
