Clinical impacts of positive intraepithelial neoplasia at pancreatic transection margin in pancreatic cancer surgery. Pancreatology 2024; 24:493-496. [PMID: 38378436 DOI: 10.1016/j.pan.2024.02.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 02/02/2024] [Accepted: 02/09/2024] [Indexed: 02/22/2024]
Abstract
BACKGROUND/OBJECTIVES The outcomes of patients with intraepithelial neoplasia at the pancreatic transection margin after pancreatic cancer surgery remain unclear. We evaluated the clinical impact of pancreatic transection margin status. METHODS This retrospective observational study included 171 patients who underwent surgery for pancreatic ductal adenocarcinoma between January 2008 and December 2019. Patients were classified into three groups: negative pancreatic transection margin (group N), positive low-grade (group L), and positive high-grade (group H) intraepithelial neoplasia. The clinicopathological findings and prognoses were analyzed for each group. RESULTS There were 140, 14, and 9 patients in groups N, L, and H, respectively. The median age was significantly higher in group H (p = 0.035). There were no significant differences in male ratio, preoperative chemotherapy administration rate, pretreatment tumor markers, operative procedure, operative time, or blood loss. Overall survival and recurrence-free survival were not significantly different; however, the cumulative risk of recurrence in the remnant pancreas was significantly higher in group H (p = 0.018). CONCLUSIONS Intraepithelial neoplasia at the pancreatic transection margin did not affect overall/recurrence-free survival. As patients with high-grade intraepithelial neoplasia at the pancreatic transection margin have an increased risk of recurrence in the remnant pancreas, careful postoperative follow-up is required.

Cancer Med 2024; 13:e7026. [PMID: 38477492 DOI: 10.1002/cam4.7026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Revised: 11/27/2023] [Accepted: 02/07/2024] [Indexed: 03/14/2024] Open
Abstract
BACKGROUND Differential diagnosis of pancreatic solid lesion (PSL) and prognosis of pancreatic cancer (PC) is a clinical challenge. We aimed to explore the differential diagnostic value of sound speed (SS) obtained from endoscopic ultrasonography (EUS) in PSL and the prognostic value of SS in PC. METHODS Patients with PSL in The Third Xiangya Hospital of Central South University from March 2019 to October 2019 were prospectively enrolled, who obtained SS from PSL. Patients were divided into the PC group and the pancreatic benign lesion (PBL) group. SS1 is the SS of lesions and SS2 is the SS of normal tissues adjacent to lesions. Ratio1 is equal to SS1 divided by SS2 of PSL (ratio1 = SS1/SS2). RESULTS Eighty patients were enrolled (24 PBL patients, 56 PC patients). SS1 and ratio1 in PC group were higher compared with PBL group (SS1:1568.00 vs. 1550.00, Z = -2.066, p = 0.039; ratio1: 1.0110 vs. 1.0051, Z = -3.391, p = 0.001). The SS1 in PC (Z = -6.503, p < 0.001) was higher compared to SS2. In the nonsurgical group of PC, low ratio1 predicted high overall survival (OS) (7.000 months vs. 4.000 months; p = 0.039). In the surgical group of PC, low SS1 was associated with low median OS (4.000 months vs. 12.000 months; p = 0.033). CONCLUSIONS SS plays a vital role in distinguishing between PBL and PC. Higher SS1 and ratio1 obtained by EUS are more related to PC than PBL. In PC patients, high SS1 may predict pancreatic lesions. In the nonsurgical group of PC, low ratio1 may predict high OS. However, in the surgical group of PC, low SS1 may predict low OS.

Utility of intraoperative pathology consultations of whipple resection specimens and their impact on final margin status. Heliyon 2023; 9:e20238. [PMID: 37810002 PMCID: PMC10560021 DOI: 10.1016/j.heliyon.2023.e20238] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Revised: 09/06/2023] [Accepted: 09/14/2023] [Indexed: 10/10/2023] Open
Abstract
The resection margin status is a significant surgical prognostic factor for the long-term outcomes of patients undergoing pancreaticoduodenectomy (Whipple procedure). As a result, surgeons frequently rely on intraoperative consults (IOCs) involving frozen sections to evaluate margin clearance during these resections. Nevertheless, the impact of this practice on final margin status and long-term outcomes remains a topic of debate. This study aimed to assess the impact of IOCs on the clearance rate of resection margins following Whipple procedure and distal pancreatectomy. A retrospective database review of all patients who underwent Whipple procedure or distal pancreatectomy at our institution between 2018 and 2020 was performed to evaluate the utility of IOCs by gastrointestinal surgeons and its correlation with final postoperative surgical margin status. A significant variation in the frequency of IOC requests for margins among surgeons was noted. However, the use of frozen section analysis for intraoperative margin assessment was not significantly associated with the clearance rate of final post-operative margins. More frequent use of IOC did not result in higher final margin clearance rate, an important prognostic factor following Whipple procedure.

Abstract
OBJECTIVE Positive resection margin indicates worse prognosis. The present study identified the independent risk factors of R1 resection in pancreaticoduodenectomy (PD) and distal pancreatosplenectomy (DP) for patients with pancreatic ductal adenocarcinoma (PDAC). METHOD Consecutive patients who were operated from 1st December 2017 to 30th December 2018 were analyzed retrospectively. A standardized pathological examination with digital whole-mount slide images (DWMSIs) was utilized for evaluation of resection margin status. R1 was defined as microscopic tumor infiltration within 1 mm to the resection margin. The potential risk factors of R1 resection for PD and DP were analyzed separately by univariate and multivariate logistic regression analyses. RESULTS For the 192 patients who underwent PD, and the 87 patients who underwent DP, the R1 resection rates were 31.8% and 35.6%, respectively. Univariate analysis on risk factors of R1 resection for PD were tumor location, lymphovascular invasion, N staging, and TNM staging; while those for DP were T staging and TNM staging. Multivariate logistic regression analysis showed the location of tumor in the neck and uncinate process, and N1/2 staging were independent risk factors of R1 resection for PD; while those for DP were T3 staging. CONCLUSIONS The clarification of the risk factors of R1 resection might clearly make surgeons take reasonable decisions on surgical strategies for different surgical procedures in patients with PDAC, so as to obtain the first attempt of R0 resection.

Abstract
The incidence of pancreatic ductal adenocarcinoma is continuously increasing and will become the second leading cause of cancer-related death in Europe and the USA by 2030. With a 5-year overall survival rate of less than 10% the prognosis remains poor. So far surgical tumor resection remains the only curative treatment option, which is now partially supported by multimodal neoadjuvant and adjuvant therapy concepts. Due to the aggressive tumor biology patients with advanced pancreatic cancer in particular can profit from these multimodal therapy concepts. Additionally, in recent years surgical treatment was optimized, the criteria for tumor resectablity were defined and minimally invasive surgery was widely introduced. This review article summarizes the newest developments and the new German S3 guidelines concerning surgery of pancreatic cancer.

Abstract
Pancreatic cancer is the eighth most common cancer and the fifth most common cause of cancer-related deaths in Korea. Despite the increasing incidence and high mortality rate of pancreatic cancer, there are no appropriate surgical practice guidelines for the current domestic medical situation. To enable standardization of management and facilitate improvements in surgical outcome, a total of 10 pancreatic surgical experts who are members of Korean Association of Hepato-Biliary-Pancreatic Surgery have developed new recommendations that integrate the most up-to-date, evidence-based research findings and expert opinions. This is an English version of the Korean Surgical Practice Guideline for Pancreatic Cancer 2021. This guideline includes 13 surgical questions and 15 statements. Due to the lack of high-level evidence, strong recommendation is almost impossible. However, we believe that this guideline will help surgeons understand the current status of evidence and suggest what to investigate further to establish more solid recommendations in the future.

Abstract
Pancreatic cancer is one of the solid tumors with the worst prognosis. Five-year survival rate is less than 10%. Surgical resection is the only potentially curative treatment, but the tumor is often diagnosed at an advanced stage of the disease and surgery could be performed in a very limited number of patients. Moreover, surgery is still associated with high post-operative morbidity, while other therapies still offer very disappointing results. This article reviews every aspect of pancreatic cancer, focusing on the elements that can improve prognosis. It was written with the aim of describing everything you need to know in 2021 in order to face this difficult challenge.

Abstract
Currently, advances in surgical techniques, improvements in perioperative care, new formulations of intermediate and long-acting insulin and of modern pancreatic enzyme preparations have allowed obtaining good short and long-term results and quality of life, especially in high-volume centres in performing total pancreatectomy (TP).Thus, the surgeon's fear in performing TP is not justified and total pancreatectomy can be considered a viable option in selected patients in high-volume centres. The aim of this review was to define the current indications for this procedure, in particular for upfront TP, considering not only the pancreatic disease, but also the surgical approach (open, mini-invasive) and the relationship with vascular resection.

Abstract
The extension of a partial pancreatectomy up to total pancreatectomy because of positive neck margin examined at intraoperative frozen section (IFS) analysis is an accepted procedure in modern pancreatic surgery with good accuracy. The goal of this practice is to improve the rate of radical (R0) resection in malignant tumors, mainly pancreatic ductal adenocarcinoma (PDAC), and to completely resect pre-invasive neoplasms such as intraductal papillary mucinous neoplasms (IPMNs). In the setting of IPMNs there is a consensus for pancreatic re-resection when high-grade dysplasia and invasive cancer are present at the neck margin. The presence of denudation is another indication for further resection in IPMNs. The role of IFS analysis in the management of pancreatic cancer is more debated. The presence of a positive intraoperative transection margin can be considered the surrogate of a biologically aggressive disease associated with a poorer prognosis. There are conflicting data regarding possible advantages of pancreatic re-resection up to total pancreatectomy, and the lack of randomized trials comparing different strategies does not offer a definitive answer. The goal of this review is to provide an up-to-date overview of the role IFS analysis of pancreatic margin and of pancreatic re-resection up to total pancreatectomy considering different pancreatic tumors.

Abstract
BACKGROUND Data on long-term actual survival in patients with surgically resected pancreatic ductal adenocarcinoma (PDAC) are limited. The aim of this study was to evaluate the actual 5-year disease-specific survival (DSS) and post-recurrence survival (PRS) in patients who underwent pancreatectomy for PDAC. METHODS Data from patients who underwent upfront surgical resection for PDAC between 2009 and 2014 were analyzed. Exclusion criteria included PDAC arising in the background of an intraductal papillary mucinous neoplasm and patients undergoing neoadjuvant therapy. All alive patients had a minimum follow-up of 60 months. Independent predictors of PRS, DSS, and survival > 5 years were searched. RESULTS Of the 176 patients included in this study, 48 (27%) were alive at 5 years, but only 20 (11%) had no recurrence. Median PRS was 12 months. In the 154 patients after disease recurrence, independent predictors of shorter PRS were total pancreatectomy, G3 tumors, early recurrence (< 12 months from surgery), and no treatment at recurrence. Median DSS was 36 months. Independent predictors of DSS were CA19-9 at diagnosis > 200 U/mL, total pancreatectomy, N + status, G3 tumors and perineural invasion. Only the absence of perineural invasion was a favorable independent predictor of survival > 5 years. CONCLUSION More than one-quarter of patients who underwent upfront surgery for PDAC were alive after 5 years, although only 11% of the initial cohort were cancer-free. Long-term survival can also be achieved in tumors with more favorable biology in an upfront setting followed by adjuvant chemotherapy.

The oncological benefit of achieving a negative pancreatic neck margin through re-resection after a positive frozen section (FS) is debated. Aim of this network meta-analysis is to evaluate the survival benefit of re-resection after intraoperative FS neck margin examination following pancreatectomy for ductal adenocarcinoma. A systematic search of studies comparing different strategies for the management of positive FS was performed. Patients were classified in three groups based on FS and permanent section (PS): Group A (FS-, PS-R0), Group B (FS+, PS-R0), Group C (FS±, PS-R1). A frequent random-effects network-meta-analysis was made reporting the surface under the cumulative ranking (SUCRA). Primary endpoint was overall survival (OS). Secondary endpoints were pathological outcomes. Seven retrospectives studies with 4205 patients were included and 99.1% of the pancreatic resections were pancreatoduodenectomies. Group A had the highest probability of better OS (SUCRA = 90%), compared to Group B (SUCRA = 48.7%) and Group C, which was the worst prognostic scenario (SUCRA = 11.3%). Group B had still a probability of longer OS compared to Group C (SUCRA = 48.7% vs 11.3%). Pathological features were more favourable in Group A, with the highest SUCRA for T1-T2 tumors (92.6%), N0 status (89.4%), absence of perineural invasion (92.3%). Heterogeneity was low (τ-value <0.1) for OS, and moderate (τ-values: 0.1-0.6) for pT, pN, and perineural invasion. In conclusion, negative neck margin after primary resection (FS negative) or re-resection of a positive FS was associated with improved survival compared with PS-R1. However, any intraoperative positive FS can be considered as a prognostic factor associated with a more aggressive disease.

Impact of intraoperative margin clearance on survival following pancreatoduodenectomy for pancreatic cancer: a systematic review and meta-analysis. Sci Rep 2020; 10:22178.

Abstract
The use of intraoperative margin revision to achieve margin clearance in patients undergoing pancreatoduodenectomy for pancreatic cancer is controversial. We performed a systematic review and meta-analysis to summarize the evidence of intraoperative margin revisions of the pancreatic neck and its impact on overall survival (OS). Nine studies with 4501 patients were included. Patient cohort was stratified in an R0R0-group (negative margin on frozen and permanent section), R1R0-group (revised positive margin on frozen section which turned negative on permanent section), and R1R1-group (positive margin on frozen and permanent section despite margin revision). OS was higher in the R1R0-group (HR 0.83, 95% CI 0.72-0.96, P = 0.01) compared to the R1R1-group but lower compared to the R0R0-group (HR 1.20; 95% CI 1.05-1.37, P = 0.008), respectively. Subgroup analyses on the use of different margin clearance definitions confirmed an OS benefit in the R1R0-group compared to the R1R1-group (HR 0.81; 95% CI 0.65-0.99, P = 0.04). In conclusion, intraoperative margin clearance of the pancreatic neck margin is associated with improved OS while residual tumor indicates aggressive tumor biology. Consensus definitions on margin terminologies, clearance, and surgical techniques are required.

Vascular resection during pancreatectomy for pancreatic head cancer: A technical issue or a prognostic sign? Surgery 2020; 169:403-410. [PMID: 32912782 DOI: 10.1016/j.surg.2020.08.002] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2020] [Revised: 07/11/2020] [Accepted: 08/05/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND There is an increased interest in venous vascular resection associated with pancreatic resection for pancreatic ductal adenocarcinoma as an upfront procedure or after neoadjuvant treatment. The aim of this study was to evaluate the impact of venous vascular resection for pancreatic ductal adenocarcinoma on postoperative and long-term outcomes. METHODS The study is a retrospective analysis of patients who underwent pancreatectomy for pancreatic head pancreatic ductal adenocarcinoma with and without venous vascular resection between January 2010 and April 2018. The impact of venous vascular resection on postoperative and pathologic data was analyzed. Univariate and multivariate analyses of predictors of disease-free and disease-specific survival were analyzed for the entire cohort. A propensity-score matched cohort analysis was subsequently performed to remove selection bias and improve homogeneity. RESULTS Four hundred and eighty-one patients were included, and 126 (26%) underwent a venous vascular resection. Patients undergoing venous vascular resection had higher morbidity (64% vs 54%; P = .026) with no differences in 90-day postoperative mortality (3.1 vs 2.8%; P = .5). Venous vascular resections were also significantly associated with R1 resections (52% vs 37%; P = .002) and perineural invasion (87% vs 77%; P = .017). Five-year disease-free survival in patients with and without venous vascular resection were 7% and 20% (P = .018), respectively. Independent predictors of worse disease-free survival included venous vascular resection, positive lymph node status, and perineural invasion. Independent predictors of worse disease-specific survival were perineural invasion and positive nodal status, while adjuvant treatment was a protective factor. Five-year disease-specific survival in patients with and without venous vascular resection were 19% and 35% (P = .42). CONCLUSION Pancreatectomy with venous vascular resection can be accomplished safely. Venous vascular resections are associated with poor prognostic factors and with a worse clinical outcome, being a significant predictor of cancer recurrence.
