Varty GP, Goel M, Nandy K, Deodhar K, Shah T, Patkar S. Role of Intraoperative Frozen Section Assessment of Proximal Bile Duct Margins and the Impact of Additional Re-Resection in Perihilar Cholangiocarcinomas. Indian J Surg Oncol 2024; 15:281-288. [PMID: 38818011 PMCID: PMC11133294 DOI: 10.1007/s13193-024-01874-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Accepted: 01/03/2024] [Indexed: 06/01/2024] Open
Abstract
Intraoperative frozen section (FS) analysis to assess the bile duct margin status is commonly used to assess the completeness of resection during surgery for perihilar cholangiocarcinoma (pCCA) resection. However, the impact of additional re-section on the long-term outcome after obtaining an initial positive margin remains unclear. Patients diagnosed as pCCA on preoperative imaging and subjected to curative intent surgery from May 2013 to June 2021 with a minimum follow-up of 2 years were included. Intraoperative FS analysis of the proximal bile duct margin was performed in all patients. A positive margin was defined by the presence of invasive cancer. Out of the 62 patients with a preoperative diagnosis of pCCA on imaging, 35 patients were included for final analyses after excluding patients with inoperable disease (on staging laparoscopy or local exploration) and other/benign pathology on the final histopathology report. Out of the 35 patients, patients with postoperative 90-day mortality were excluded from the final survival analysis. FS analysis revealed an initial positive margin in 10 (28.5%) patients. Among 10 patients who underwent re-resection to achieve negative proximal margins, only 5 patients achieved a negative margin (secondary R0). An initial positive margin was associated with poor long-term outcomes. Median disease-free survival (DFS) and overall survival (OS) were 16 and 19.6 months for patients with an initial positive margin, but 36 and 58.2 months for patients with an initial negative margin, respectively (p = 0.012). The median DFS and OS were significantly lower for those with secondary R0 as compared to primary R0 (16 vs. 36 months for DFS, p = 0.117 and 19.6 vs. 58.2 months for OS, p = 0.027, respectively). An intraoperative FS positive proximal hepatic duct margin dictates poor long-term outcomes for patients with resectable pCCA. Additional resection has a questionable benefit on survival, when a secondary negative margin is achieved.

Radial and longitudinal margins in surgery of perihilar cholangiocarcinoma: When R1 definition is associated with different prognosis. Surgery 2023; 174:447-456. [PMID: 37357095 DOI: 10.1016/j.surg.2023.05.014] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Revised: 04/15/2023] [Accepted: 05/24/2023] [Indexed: 06/27/2023]
Abstract
BACKGROUND Infiltrated margins of resection (R1) and lymph node invasion are dominant negative predictors of survival in patients with a resectable perihilar cholangiocarcinoma. Less clear is whether survival predictors stratify differently between R0 (tumor-free margins) and R1 patients and whether the prognosis of the latter patients is influenced by the pattern of neoplastic infiltration (ie, radial versus longitudinal infiltration). We retrospectively evaluated a series of reported resected perihilar cholangiocarcinoma to obtain insights on the predictive power of these histologic features. METHODS The study includes 264 patients with perihilar cholangiocarcinoma treated between 2004 and 2019 in our center and followed up for >18 months. There were 176 patients with R0 (66.6%) and 88 patients with R1 (33.3%), 31 with radial infiltration only, 30 with longitudinal infiltration only, and 27 with both infiltration patterns. In all patients, the criteria for resection was the absence of metastatic involvement (ie, distant organ metastases, liver metastases, and lymph node metastases beyond the hepatoduodenal ligament). Histopathologic specimens of the resected tumors were centrally reviewed by a pathologist unaware of the clinical outcomes. RESULTS Three- and 5-year long-term survival were significantly better in R0 (respectively) compared to R1 patients (55% and 42% vs 42% and 18%, respectively, P < .05). In R1 patients with radial infiltration only and those with radial + longitudinal infiltration, both disease-free and overall survival were worse than those with longitudinal infiltration only (median disease-free survival of 18 and 23 months, respectively, P < .05, median overall survival of 33 and 39 months, respectively, P < .05). At multivariable analysis, nodal status, side of hepatectomy, grading, and presence of radial margin infiltration were associated with long-term outcome. CONCLUSION Radial infiltration of resection margins enhances the negative prognostic value of R1 margins in perihilar cholangiocarcinoma patients and should specifically be accounted for in the prediction of the outcome of adjuvant therapy.

Value of routine intraoperative frozen sections of proximal bile duct margins in perihilar cholangiocarcinoma, a retrospective multicenter and matched case-control study. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2022; 48:2424-2431. [PMID: 35729016 DOI: 10.1016/j.ejso.2022.06.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Revised: 05/23/2022] [Accepted: 06/07/2022] [Indexed: 12/14/2022]
Abstract
BACKGROUND Currently, the potential benefits of additional resection after positive proximal intraoperative frozen sections (IFS) in perihilar cholangiocarcinoma (pCCA) on residual disease and oncological outcome remain uncertain. Therefore, the aim of this study is to investigate the number of R0 resections after additional resection of a positive proximal IFS and the influence of additional resections on overall survival (OS) in patients with pCCA. MATERIALS AND METHODS A retrospective, multicenter, matched case-control study was performed, including patients undergoing resection for pCCA between 2000 and 2019 at three tertiary centers. Primary outcome was the number of achieved 'additional' R0 resections. Secondary outcomes were OS, recurrence, severe morbidity and mortality. RESULTS Forty-four out of 328 patients undergoing resection for pCCA had a positive proximal IFS. An additional resection was performed in 35 out of 44 (79.5%) patients, which was negative in 24 (68.6%) patients. Nevertheless, seven out of these 24 patients were eventually classified as R1 resection due to other positive resection margins. Therefore, 17 (48.6%) patients could be classified as "true" R0 resection after additional resection. Ninety-day mortality after R1 resections was high (25%) and strongly influenced OS. After correction for 90-day mortality, median OS after negative additional resection was 33 months (95%CI:29.5-36.5) compared to 30 months (95%CI:24.4-35.6) after initial R1 (P = 0.875) and 46 months (95%CI:32.7-59.3) after initial R0 (P = 0.348). CONCLUSION There were only 17 patients (out of a total of 328 patients) that potentially benefitted from routine IFS. Additional resection for a positive IFS leading to R0 resection was not associated with improved long-term survival.

Defining Facility Volume Threshold for Optimization of Short- and Long-Term Outcomes in Patients Undergoing Resection of Perihilar Cholangiocarcinoma. J Gastrointest Surg 2022; 27:730-740. [PMID: 36138311 DOI: 10.1007/s11605-022-05465-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Accepted: 09/10/2022] [Indexed: 01/31/2023]
Abstract
BACKGROUND We determined the minimum threshold (Tmin) of annual facility case volume to optimize outcomes for patients with resected perihilar cholangiocarcinoma. METHODS We identified patients with localized perihilar cholangiocarcinoma who underwent resection within the National Cancer Database (2010-2017). We used marginal structural logistic regression models to estimate the average treatment effect of receiving care in facilities meeting/exceeding Tmin on 90-day mortality and other postoperative outcomes. RESULTS A total of 2471 patients underwent resection for perihilar cholangiocarcinoma at 471 facilities. There was no effect of total hepatopancreatobiliary, surgical hepatopancreatobiliary, total hepatobiliary, surgical hepatobiliary, or total perihilar cholangiocarcinoma case volume on 90-day mortality. A Tmin of seven perihilar cholangiocarcinoma resections/year resulted in lower odds of 90-day mortality (IP-weighted OR = 0.49, 95% CI: 0.66-0.87). A total of two facilities met the Tmin. Patients receiving treatment at Tmin facilities had lower odds of length of stay ≥ 7 days (IP-weighted OR = 0.85, 95% CI: 0.75-0.97) and positive surgical resection margins (IP-weighted OR = 0.40, 95% CI: 0.47-0.55). Additionally, undergoing surgery at Tmin facilities resulted in higher (≥ 4 nodes) lymph node yields (IP-weighted OR = 1.94, 95% CI: 1.21-3.11) but no change in the odds of nodal positivity. There was no effect of undergoing surgery at Tmin facilities on 30-day mortality or re-admission. CONCLUSIONS Resection of perihilar cholangiocarcinoma is infrequently performed at a high number of facilities. A Tmin of ≥ 7 resections/year resulted in lower 90-day mortality and improved postoperative outcomes. Our data suggest that regionalization of care for patients with perihilar cholangiocarcinoma could potentially improve outcomes in the USA.

Does Intraoperative Frozen Section and Revision of Margins Lead to Improved Survival in Patients Undergoing Resection of Perihilar Cholangiocarcinoma? A Systematic Review and Meta-analysis. Ann Surg Oncol 2022; 29:7592-7602.

Abstract
BACKGROUND Perihilar cholangiocarcinoma (PHC) is a rare malignancy that arises at the biliary confluence. Achieving a margin-negative resection (R0) is challenging given the anatomic location of tumors and remains the most important prognostic indicator of long-term survival. The objective of this study is to review the impact of intraoperative revision of positive biliary margins in PHC on oncologic outcomes. PATIENTS AND METHODS Electronic databases were searched from inception to October 2021. Studies comparing three types of patients undergoing resection of PHC with intraoperative frozen section of the proximal and/or distal bile ducts were identified: those who were margin-negative (R0), those with an initially positive margin who had revised negative margins (R1R0), and those with a persistently positive margin with or without revision of a positive margin (R1). The primary outcome was overall survival (OS). Secondary outcomes included risk of postoperative complication. RESULTS A total of 449 studies were screened. Ten retrospective observational studies reporting on 1955 patients were included. Patients undergoing successful revision of a positive proximal and/or distal bile duct margin (R1R0) had similar OS to those with a primary margin-negative resection (R0) [hazard ratio (HR) 0.93, 95% confidence interval (CI) 0.72-1.19, p = 0.56, I2 = 84%], and significantly better OS than patients with a positive final bile duct margin (R1) (HR 0.52, 95% CI 0.34-0.79, p = 0.002, I2 = 0%). There was no increase in the risk of postoperative complications associated with additional resection, although postoperative morbidity was inconsistently reported. CONCLUSIONS This review supports routine intraoperative biliary margin evaluation during resection of PHC with revision if technically feasible.
