Abstract
Objectives This research aimed to assess the value of radiomics combined with multiple machine learning algorithms in the diagnosis of pancreatic ductal adenocarcinoma (PDAC) lymph node (LN) metastasis, which is expected to provide clinical treatment strategies. Methods A total of 128 patients with pathologically confirmed PDAC and who underwent surgical resection were randomized into training (n=93) and validation (n=35) groups. This study incorporated a total of 13 distinct machine learning algorithms and explored 85 unique combinations of these algorithms. The area under the curve (AUC) of each model was computed. The model with the highest mean AUC was selected as the best model which was selected to determine the radiomics score (Radscore). The clinical factors were examined by the univariate and multivariate analysis, which allowed for the identification of factors suitable for clinical modeling. The multivariate logistic regression was used to create a combined model using Radscore and clinical variables. The diagnostic performance was assessed by receiver operating characteristic curves, calibration curves, and decision curve analysis (DCA). Results Among the 233 models constructed using arterial phase (AP), venous phase (VP), and AP+VP radiomics features, the model built by applying AP+VP radiomics features and a combination of Lasso+Logistic algorithm had the highest mean AUC. A clinical model was eventually constructed using CA199 and tumor size. The combined model consisted of AP+VP-Radscore and two clinical factors that showed the best diagnostic efficiency in the training (AUC = 0.920) and validation (AUC = 0.866) cohorts. Regarding preoperative diagnosis of LN metastasis, the calibration curve and DCA demonstrated that the combined model had a good consistency and greatest net benefit. Conclusions Combining radiomics and machine learning algorithms demonstrated the potential for identifying the LN metastasis of PDAC. As a non-invasive and efficient preoperative prediction tool, it can be beneficial for decision-making in clinical practice.

Ann Surg Oncol 2023; 30:1474-1482. [PMID: 36305986 DOI: 10.1245/s10434-022-12700-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2022] [Accepted: 10/05/2022] [Indexed: 12/23/2022]
Abstract
BACKGROUND The short-term outcome and long-term survival of pancreaticoduodenectomy with additional para-aortic dissection (PAD) for patients with resectable pancreatic cancer remain obscure. PATIENTS AND METHODS Consecutive patients who underwent radical pancreaticoduodenectomy for resectable pancreatic cancer in a single high-volume center during a 7-year period were included retrospectively. Both short- and long-term effects of PAD were compared between the PAD group and the no PAD group. Then, the PAD group was divided into the non-metastatic para-aortic lymph node (PALN-) group and the metastatic PALN (PALN+) group to further analyze the prognosis of PALN+. RESULTS Of the 909 included patients, 280 (30.8%) underwent PAD during pancreaticoduodenectomy. The PAD group had a higher rate of intra-abdominal infection compared with the no PAD group (28.6% vs. 20.7%, P = 0.009) but no differences were found in the incidence of other complications. The overall survival (OS) and recurrence-free survival (RFS) were also comparable between the two groups. Subgroup analysis showed that patients with PALN+ had a worse OS than patients in the PALN- group (median of 14 vs. 20 months, P = 0.048). Multivariate Cox regression analysis further revealed that PALN+ was an independent adverse predictor of OS (hazard ratio: 1.70, P = 0.007). CONCLUSIONS This study suggests that the addition of PAD during pancreaticoduodenectomy does not improve the prognosis of patients with resectable pancreatic cancer and may lead to an increased risk of infection. However, the accurate preoperative assessment and appropriate treatment strategy for patients with PALN+ need further investigation due to the poor prognosis.

Standard pancreatoduodenectomy versus extended pancreatoduodenectomy with modified retroperitoneal nerve resection in patients with pancreatic head cancer: a multicenter randomized controlled trial. Cancer Commun (Lond) 2022; 43:257-275. [PMID: 36579790 PMCID: PMC9926959 DOI: 10.1002/cac2.12399] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2022] [Revised: 12/11/2022] [Accepted: 12/14/2022] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND The extent of pancreatoduodenectomy for pancreatic head cancer remains controversial, and more high-level clinical evidence is needed. This study aimed to evaluate the outcome of extended pancreatoduodenectomy (EPD) with retroperitoneal nerve resection in pancreatic head cancer. METHODS This multicenter randomized trial was performed at 6 Chinese high-volume hospitals that enrolled patients between October 3, 2012, and September 21, 2017. Four hundred patients with stage I or II pancreatic head cancer and without specific pancreatic cancer treatments (preoperative chemotherapy or chemoradiation) within three months were randomly assigned to undergo standard pancreatoduodenectomy (SPD) or EPD, with the latter followed by dissection of additional lymph nodes (LNs), nerves and soft tissues 270° on the right side surrounding the superior mesenteric artery and celiac axis. The primary endpoint was overall survival (OS) by intention-to-treat (ITT). The secondary endpoints were disease-free survival (DFS), mortality, morbidity, and postoperative pain intensity. RESULTS The R1 rate was slightly lower with EPD (8.46%) than with SPD (12.56%). The morbidity and mortality rates were similar between the two groups. The median OS was similar in the EPD and SPD groups by ITT in the whole study cohort (23.0 vs. 20.2 months, P = 0.100), while the median DFS was superior in the EPD group (16.1 vs. 13.2 months, P = 0.031). Patients with preoperative CA19-9 < 200.0 U/mL had significantly improved OS and DFS with EPD (EPD vs. SPD, 30.8 vs. 20.9 months, P = 0.009; 23.4 vs. 13.5 months, P < 0.001). The EPD group exhibited significantly lower locoregional (16.48% vs. 35.20%, P < 0.001) and mesenteric LN recurrence rates (3.98% vs. 10.06%, P = 0.022). The EPD group exhibited less back pain 6 months postoperation than the SPD group. CONCLUSIONS EPD for pancreatic head cancer did not significantly improve OS, but patients with EPD treatment had significantly improved DFS. In the subgroup analysis, improvements in both OS and DFS in the EPD arm were observed in patients with preoperative CA19-9 < 200.0 U/mL. EPD could be used as an effective surgical procedure for patients with pancreatic head cancer, especially those with preoperative CA19-9 < 200.0 U/mL.

Abstract
BACKGROUND Para-aortic lymph node (PALN) metastases in pancreatic ductal adenocarcinoma (PDAC) correlates with poor prognosis. The role of PALN in invasive intraductal papillary mucinous neoplasms (inv-IPMN) has not been well explored. The present study investigated the rate of metastatic PALN, lymph node ratio (LNR) and the overall nodal (N) status as prognostic factors in PDAC and inv-IPMN. METHODS This consecutive single-center series included patients with PDAC or inv-IPMN in the pancreatic head who underwent pancreatoduodenectomy or total pancreatectomy, including PALN resection between 2009 and 2018. Median overall survival (mOS) and impact of clinicopathological factors, including PALN status on survival, were evaluated. RESULTS 403 patients were included, 314 had PDAC and 89 inv-IPMN. PALN were metastatic in 16% of PDAC and 17% of inv-IPMN. N0 status was present in 6% of the patients with PDAC and 16% of inv-IPMN patients (p = 0.007). LNR >15% was more common in PDAC (52%) than in inv-IPMN (34%) (p = 0.004). mOS was 12.7 months in the presence of PALN metastases and 22.7 months without (p < 0.0001). Age >70 years, CA19-9 >200 U/mL, PDAC and N2 status were significantly associated with worse survival in a multivariable analysis. PALN status and LNR were not independent prognostic factors. In N2 status mOS was similar regardless the presence of PALN metastases. CONCLUSION The frequency of PALN metastases was similar in PDAC and inv-IPMN. Although PALN positive status entailed a shorter mOS, it was not an independent risk factor for death, and did not influence survival in N2-staged disease. The M1-status for PALN positivity may need reconsideration.

Intraoperative frozen section analysis of para-aortic lymph nodes after neoadjuvant FOLFIRINOX: will it soon become useless? Langenbecks Arch Surg 2022; 407:1065-1071.

Abstract
PURPOSE Positive para-aortic lymph nodes (PALN) (station 16) are commonly detected in the final pathologic examination (ranging from 15 to 26%) among patients who undergo upfront pancreatoduodenectomy for resectable pancreatic ductal adenocarcinoma. However, after neoadjuvant treatment (NAT) the role of positive PALN as a watershed for surgical resection remains unclear. We aimed to determine the incidence of intraoperative detection of PALN after NAT with FOLFIRINOX for pancreatic head adenocarcinoma and its impact on survival, as our policy was to not resect the tumor in such situations. METHODS From January 2014 to December 2020, 136 patients with non-metastatic cancer who received neoadjuvant FOLFIRINOX and underwent explorative laparotomy were included. RESULTS Intraoperative positive PALN were observed in 7 patients (5%). Patients had resectable (n = 5) or locally advanced (n = 2) disease at the time of surgery, but none of them underwent surgical resection. Positive PALN were significantly associated with a lower median number of FOLFIRINOX cycles (4 vs. 6, P = 0.05). There was no significant difference in overall survival between patients with positive loco-regional lymph nodes after resection and patients with non-resection owing to positive PALN (22 versus 16 months, P = 0.16), Overall survival with positive PALN, carcinomatosis, and liver metastasis was 16, 14, and 10 months, respectively (P > 0.05). CONCLUSIONS Our results suggest that NAT may lower PALN involvement. We have modified our policy, positive PALN after NAT are no longer a contraindication to resection, rather a holistic picture of the disease guides management.

Predictive model for the intraoperative unresectability of hilar cholangiocarcinoma: Reducing futile surgical exploration. PLoS One 2022; 17:e0258522. [PMID: 35417458 PMCID: PMC9007352 DOI: 10.1371/journal.pone.0258522] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2021] [Accepted: 09/29/2021] [Indexed: 12/25/2022] Open
Abstract
Introduction Surgical exploration is widely performed in hilar cholangiocarcinoma (HCCA), but the intraoperative resectability rate is only 60%-80%. Exploration substantially increases pain and mental stress, and the costs and length of hospital stay are considerably increased. Identifying preoperative risk factors associated with unresectability could decrease unnecessary exploration. Materials and methods In total, 440 HCCA patients from multiple centers were enrolled. Those receiving surgical exploration were divided into the resected and unresected groups. Morphological variables including Bismuth classification, lymph node metastasis and vessel invasion were obtained from radiological exams. Logistic regression for the training cohort was used to identify risk factors for unresectability, and a nomogram was constructed to calculate the unresectability rate. A calibration curve assessed the power of the nomogram. Results Among 311 patients receiving surgical exploration, 45 (14.7%) were unresectable by intraoperative judgment. Compared with the resected group, unresected patients had similar costs (p = 0.359) and lengths of hospital stay (p = 0.439). Multivariable logistic regression of the training cohort (235 patients) revealed that CA125, Bismuth-Corlette type IV, lymph node metastasis and hepatic artery invasion were risk factors for unresectability. Liver atrophy (p = 0.374) and portal vein invasion (p = 0.114) were not risk factors. The nomogram was constructed based on the risk factors. The concordance index (C-index) values of the calibration curve for predicting the unresectability rate of the training and validation (76 patients) cohorts were 0.900 (95% CI, 0.835–0.966) and 0.829 (95% CI, 0.546–0.902), respectively. Conclusion Analysis of preoperative factors could reveal intraoperative unresectability and reduce futile surgical explorations, ultimately benefiting HCCA patients.

Ann Hepatobiliary Pancreat Surg 2022; 26:1-16. [PMID: 35220285 PMCID: PMC8901981 DOI: 10.14701/ahbps.22-009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 02/17/2022] [Accepted: 02/17/2022] [Indexed: 11/17/2022] Open
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.

J Gastrointest Oncol 2021; 12:2450-2460.

Abstract
The possibility of surgical resection strongly overrules medical oncologic treatment and is the only modality, causa sine qua non, long-term survival can be achieved in patients with pancreatic cancer. For this reason, the clinical classification of local resectability, subdividing tumors into resectable, borderline resectable, and locally advanced cancer, that is very technical in nature, is the one most widely used and accepted. As multimodality treatment with potent agents, particularly in the neoadjuvant setting, seems to be stepping forward as the new standard of treatment of pancreatic cancer, the established technical surgical landmarks tend to get challenged. This review aims to highlight the grey zones in the current classifications for local tumor involvement with respect to the observed patient outcome in the current multimodality treatment era. It summarizes the latest reported series on the outcome of resected primary resectable, borderline and locally advanced pancreatic cancer, and particularly vascular resections during pancreatectomy, in the background of different types of neoadjuvant therapy. It also hints what the new horizons of cancer biology tend to reveal whenever the technical hinders start being pushed aside. The current calls for the necessity of re-classification of the clinical categories of pancreatic cancer, from technically oriented to biology-focused individualized approach, are being elucidated.

Abstract
Backgrounds/Aims Pancreaticoduodenectomy (PD) is the gold standard for the treatment of periampullary tumors. Many specialized centers have adopted the totally laparoscopic or hybrid laparoscopic PD (LPD). However, this procedure has not yet been standardized and serious debate is taking place towards its safety and feasibility. Herein, we report our recent experience whit hybrid-LPD. Methods During 2019 in our department 56 PD were performed and 21 (37.5%) underwent hybrid-LPD. We have retrospectively reviewed the short-term outcomes of these patients. Results Main indication was pancreatic adenocarcinoma (71,4%). The median operative time and intraoperative blood loss were respectively 425 min (range, 226 to 576) and 317 ml (range 60 to 800 ml). Conversion to an open procedure was required in 4 patients (19%): 2 with suspected vein involvement, 1 for mesenteric panniculitis and 1 for biliary injury. The post-operative complication rate was 42.8% (9/21). Regarding post-operative pancreatic fistula, three patients (14.2%) had grade B and 1 grade C (4.7%). Median length of hospital stay was 14 days (range 9-23) and 90- days mortality was 4.7%. The mean number of harvested lymph nodes was 17.7 (range 12 to 26). The rate of margins R0 was 80%; R1 >0<1 mm was 10.5% and R1 0 mm was 9.5%. Conclusions Hydrid-LPD is safe and feasible. Careful patient selection and increasing experience can reduce the risk of post-operative complications.

The clinical impact of splenic artery ligation on the occurrence of digestive varices after pancreaticoduodenectomy with combined portal vein resection: a retrospective study in two institutes. Langenbecks Arch Surg 2020; 406:1469-1479.

Abstract
PURPOSE Pancreaticoduodenectomy (PD) concomitant with portal vein resection (PVR) often develops into digestive varices with an occurrence rate of 30-50%, and the variceal bleeding is sometimes untreatable and results in fatality. Against this issue, splenic artery (SpA) ligation during PD-PVR is emerging as an easy and effective prophylactic surgical option. The aim of this study was to investigate the significance of SpA ligation in the development of digestive varices in patients undergoing PD-PVR. METHOD We retrospectively investigated 97 patients with PDAC who received PD-PVR in two hospitals. Vascular reconstruction of the splenic vein (SpV) was not performed in either hospital. We assessed the occurrence rate of digestive varices in these patients in association with the performance of SpA ligation. RESULTS The occurrence rate of digestive varices was 23%. SpA ligation was the only significant decreasing factor for the development of digestive varices (odds ratio 0.3, p = 0.035). Although SpV resection was not a significant risk factor for the development of digestive varices in all patients, SpV resection was a significant risk factor for the development of digestive varices in patients without SpA ligation, as demonstrated in previous reports. SpA ligation did not increase surgical complications or impair pancreatic function. CONCLUSION PD-PVR surgery was accompanied by a 23% incidence of digestive varices, and SpA ligation significantly decreased the development of digestive varices without causing clinically significant complications.
