[PMID: 38802630 DOI: 10.1007/s00261-024-04299-4] [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: 12/06/2023] [Revised: 03/17/2024] [Accepted: 03/20/2024] [Indexed: 05/29/2024]
Abstract
OBJECTIVES The purpose of this study was to compare the different versions of the National Comprehensive Cancer Network (NCCN) guidelines for defining resectability of pancreatic ductal adenocarcinoma (PDAC) in predicting margin-negative (R0) resection, and to assess inter-reader agreement. METHODS This retrospective study included 283 patients (mean age, 65.1 years ± 9.4 [SD]; 155 men) who underwent upfront pancreatectomy for PDAC between 2017 and 2019. Two radiologists independently determined the resectability on preoperative CT according to the 2017, 2019, and 2020 NCCN guidelines. The sensitivity and specificity for R0 resection were analyzed using a multivariable logistic regression analysis with generalized estimating equations. Inter-reader agreement was assessed using kappa statistics. RESULTS R0 resection was accomplished in 239 patients (84.5%). The sensitivity and specificity averaged across two readers were, respectively, 76.6% and 29.5% for the 2020 guidelines, 74.1% and 32.9% for the 2019 guidelines, and 72.6% and 34.1% for the 2017 guidelines. Compared with the 2020 guidelines, both 2019 and 2017 guidelines showed significantly lower sensitivity for R0 resection (p ≤ .009). Specificity was significantly higher with the 2017 guidelines (p = .043) than with the 2020 guidelines. Inter-reader agreements for determining the resectability of PDCA were strong (k ≥ 0.83) with all guidelines, being highest with the 2020 guidelines (k = 0.91). CONCLUSION The 2020 NCCN guidelines showed significantly higher sensitivity for prediction of R0 resection than the 2017 and 2019 guidelines.

Abstract
Locally advanced pancreatic cancer (LAPC), which progresses locally and surrounds major vessels, has historically been deemed unresectable. Surgery alone failed to provide curative resection and improve overall survival. With the advancements in treatment, reports have shown favorable results in LAPC after undergoing successful chemotherapy therapy or chemoradiation therapy followed by surgical resection, so-called "conversion surgery", at experienced high-volume centers. However, recognizing significant regional and institutional disparities in the management of LAPC, an international consensus meeting on conversion surgery for LAPC was held during the Joint Congress of the 26th Meeting of the International Association of Pancreatology (IAP) and the 53rd Annual Meeting of Japan Pancreas Society (JPS) in Kyoto in July 2022. During the meeting, presenters reported the current best multidisciplinary practices for LAPC, including preoperative modalities, best systemic treatment regimens and durations, procedures of conversion surgery with or without vascular resections, biomarkers, and genetic studies. It was unanimously agreed among the experts in this meeting that "cancer biology is surpassing locoregional anatomical resectability" in the era of effective multiagent treatment. The biology of pancreatic cancer has yet to be further elucidated, and we believe it is essential to improve the treatment outcomes of LAPC patients through continued efforts from each institution and more international collaboration. This article summarizes the agreement during the discussion amongst the experts in the meeting. We hope that this will serve as a foundation for future international collaboration and recommendations for future guidelines.

Abstract
OBJECTIVE The aim of this study was to investigate the safety and survival benefits of portal vein and/or superior mesenteric vein (PV/SMV) resection with jejunal vein resection (JVR) for pancreatic ductal adenocarcinoma (PDAC). SUMMARY BACKGROUND DATA Few studies have shown the surgical outcome and survival of pancreatic resection with JVR, and treatment strategies for patients with PDAC suspected of jejunal vein (JV) infiltration remain unclear. METHODS In total, 1260 patients who underwent pancreatectomy with PV/ SMV resection between 2013 and 2016 at 50 facilities were included; treatment outcomes were compared between the PV/SMV group (PV/ SMV resection without JVR; n = 824), PV/SMV-J1 V group (PV/SMV resection with first jejunal vein resection; n = 394), and PV/SMV-J2,3 V group (PV/SMV resection with second jejunal vein or later branch resection; n = 42). RESULTS Postoperative complications and mortality did not differ between the three groups. The postoperative complication rate associated with PV/ SMV reconstruction was 11.9% in PV/SMV group, 8.6% in PV/SMV-J1 V group, and 7.1% in PV/SMV-J2,3V group; there were no significant differences among the three groups. Overall survival did not differ between PV/SMV and PV/SMV-J1 V groups (median survival; 29.2 vs 30.9 months, P = 0.60). Although PV/SMV-J2,3 V group had significantly shorter survival than PV/SMV group who underwent upfront surgery ( P = 0.05), no significant differences in overall survival of patients who received preoperative therapy. Multivariate survival analysis revealed that adjuvant therapy and R0 resection were independent prognostic factors in all groups. CONCLUSION PV/SMV resection with JVR can be safely performed and may provide satisfactory overall survival with the pre-and postoperative adjuvant therapy.

Abstract
The improvement of effective multidrug agents has allowed more patients to undergo resection for pancreatic cancer (PC). In the conversion cases of initially unresectable PC after induction chemotherapy, pancreatic surgeons often encounter challenging vein resections cases such as those of long-segment portal vein (PV)/superior mesenteric vein (SMV) encasement or occlusion of the distal (caudal) SMV. Given the lack of consensus for the optimal approach for major vein resections and reconstructions in these situations, this review summarizes the literature on this topic and provides the best currently available approaches for challenging vein reconstruction cases. For long-segment PV/SMV encasement, tips for direct end-to-end anastomosis without grafts and the splenic vein (SpV) reconstruction to prevent left-side portal hypertension will be introduced. For distal SMV encasement, several bypass techniques to deal with collateralizations will be introduced. Even though some high-volume PC centers are obtaining favorable outcomes for challenging vein resection cases, existing evidence on this topic is limited. It is essential to organize the well-designed international multicenter studies for the small population of challenging vein resection cases. With the emergence of effective chemotherapies, the number of PC patients who can undergo curative resection is increasing. Achieving more successful vessel resection and reconstruction in the treatment of PC is a common goal that pancreatic surgeons should focus on together.

Reconsideration of the Appropriate Dissection Range Based on Japanese Anatomical Classification for Resectable Pancreatic Head Cancer in the Era of Multimodal Treatment. Cancers (Basel) 2021; 13:cancers13143605. [PMID: 34298818 PMCID: PMC8303207 DOI: 10.3390/cancers13143605] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Revised: 07/06/2021] [Accepted: 07/15/2021] [Indexed: 12/11/2022] Open
Abstract
Patients with resectable pancreatic cancer are considered to already have micro-distant metastasis, because most of the recurrence patterns postoperatively are distant metastases. Multimodal treatment dramatically improves prognosis; thus, micro-distant metastasis is considered to be controlled by chemotherapy. The survival benefit of "regional lymph node dissection" for pancreatic head cancer remains unclear. We reviewed the literature that could be helpful in determining the appropriate resection range. Regional lymph nodes with no suspected metastases on preoperative imaging may become areas treated with preoperative and postoperative adjuvant chemotherapy. Many studies have reported that the R0 resection rate is associated with prognosis. Thus, "dissection to achieve R0 resection" is required. The recent development of high-quality computed tomography has made it possible to evaluate the extent of cancer infiltration. Therefore, it is possible to simulate the dissection range to achieve R0 resection preoperatively. However, it is often difficult to distinguish between areas of inflammatory changes and cancer infiltration during resection. Even if the "dissection to achieve R0 resection" range is simulated based on the computed tomography evaluation, it is difficult to identify the range intraoperatively. It is necessary to be aware of anatomical landmarks to determine the appropriate dissection range during surgery.

Abstract
Overall survival of patients with localized pancreatic ductal adenocarcinoma (PDAC) is extremely poor. Therefore, the establishment of multimodal treatment strategies is indispensable for PDAC patients because surgical treatment alone could not contribute to the improvement of survival. In this review article, we focus on the current topics and advancement of the treatments for localized PDAC including resectable, borderline resectable, and locally advanced PDAC in accordance with the articles mainly published from 2019 to 2020. Reviewing the articles, the recent progress of multimodal treatments notably improves the prognosis of patients with localized PDAC. For resectable PDAC, neoadjuvant chemo or chemoradiation therapy, rather than upfront surgery, plays a key role, especially in patients with a large tumor, poor performance status, high tumor marker levels, peripancreatic lymph nodes metastasis, or neural invasion suspected on preoperative imaging. For borderline resectable PDAC, neoadjuvant treatments followed by surgery is a desirable approach, and maintenance of immunonutritional status during the treatments are also important. For locally advanced disease, conversion surgery has a central role in improving a survival outcome; however, its indication should be standardized.
