Subserosal Layer and/or Pancreatic Invasion Based on Anatomical Features as a Novel Prognostic Indicator in Patients with Distal Cholangiocarcinoma. Diagnostics (Basel) 2023; 13:3406. [PMID: 37998542 PMCID: PMC10670817 DOI: 10.3390/diagnostics13223406] [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: 10/05/2023] [Revised: 10/27/2023] [Accepted: 11/02/2023] [Indexed: 11/25/2023] Open
Abstract
The American Joint Committee on Cancer (AJCC) 8th edition T-staging system for distal cholangiocarcinoma (DCC) proposes classification according to the depth of invasion (DOI); nevertheless, DOI measurement is complex and irreproducible. This study focused on the fibromuscular layer and evaluated whether the presence or absence of penetrating fibromuscular invasion of DCC contributes to recurrence and prognosis. In total, 55 patients pathologically diagnosed with DCC who underwent surgical resection from 2002 to 2022 were clinicopathologically examined. Subserosal layer and/or pancreatic (SS/Panc) invasion, defined as penetration of the fibromuscular layer and invasion of the subserosal layer or pancreas by the cancer, was assessed with other clinicopathological prognostic factors to investigate recurrence and prognostic factors. According to the AJCC 8th edition, there were 11 T1, 28 T2, and 16 T3 cases, with 44 (80%) cases of SS/Panc invasion. The DOI was not significantly different for both recurrence and prognostic factors. In the multivariate analysis, only SS/Panc was identified as an independent factor for prognosis (hazard ratio: 16.1; 95% confidence interval: 2.1-118.8, p = 0.006). In conclusion, while the determination of DOI in DCC does not accurately reflect recurrence and prognosis, the presence of SS/Panc invasion may contribute to the T-staging system.

Abstract
PURPOSE Vascular resection (VR) is extended surgery to attain a negative radial margin (RM) for distal cholangiocarcinoma (DCC). The present study explored the significance of VR for DCC, focusing on VR, RM, and findings suggestive of vascular invasion on multidetector-row computed tomography (MDCT). METHODS Patients with DCC who underwent resection between 2002 and 2019 were reviewed. RESULTS Among 230 patients, 25 received VR. The overall survival (OS) in the VR group was significantly worse than in the non-VR group (16.7% vs. 50.7% at 5 years, P < 0.001). Patients who underwent VR with a negative RM failed to show a better OS than those who did not undergo VR with a positive RM (19.7% vs. 35.7% at 5 years, P = 0.178). Of the 30 patients who were suspected of having vascular invasion on MDCT, 11 did not receive VR because the vessels were freed from the tumor; these patients had a significantly better OS (57.9% at 5 years) than those who underwent VR. CONCLUSIONS VR for DCC was associated with a poor prognosis, even if a negative RM was obtained. VR is not necessary for DCC when the vessels are detachable from the tumor.

Pancreatology 2022; 22:803-809. [PMID: 35697587 DOI: 10.1016/j.pan.2022.05.001] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Revised: 02/28/2022] [Accepted: 05/02/2022] [Indexed: 12/11/2022]
Abstract
BACKGROUND In pancreatic ductal adenocarcinoma patients with suspected venous infiltration, a R0 resection is most of the time not possible without venous resection (VR). To investigate this special kind of patients, this meta-analysis was conducted to compare mortality, morbidity and long-term survival of pancreatic resections with (VR+) and without venous resection (VR-). METHODS A systematic search was performed in Embase, Pubmed and Web of Science. Studies which compared over twenty patients with VR + to VR-for PDAC with ≥1 year follow up were included. Articles including arterial resections were excluded. Statistical analysis was performed with the random effect Mantel-Haenszel test and inversed variance method. Individual patient data was compared with the log-rank test. RESULTS Following a review of 6403 papers by title and abstract and 166 by full text, a meta-analysis was conducted of 32 studies describing 2216 VR+ and 5380 VR-. There was significantly more post-pancreatectomy hemorrhage (6.5% vs. 5.6%), R1 resections (36.7% vs. 28.6%), N1 resections (70.3% vs. 66.8%) and tumors were significantly larger (34.6 mm vs. 32.8 mm) in patients with VR+. Of all VR + patients, 64.6% had true pathological venous infiltration. The 90-day mortality, individual patient data for overall survival and pooled multivariate hazard ratio for overall survival were similar. CONCLUSION VR is a safe and feasible option in patients with pancreatic cancer and suspicion of venous involvement, since VR during pancreatic surgery has comparable overall survival and complication rates.

Abstract
Background To analyze population-level data for resectable gallbladder carcinoma (GBC) according to the eighth edition of the American Joint Committee on Cancer staging system. Methods We queried the Surveillance, Epidemiology, and End Results database to identify all patients aged 18 years or older with T1-3 M0 GBC diagnosed between 2004 and 2015. Multivariate cox hazard regression analysis was used to identify prognostic factors of cancer-specific survival (CSS). Results Of the 1601 eligible patients, 1310 (81.8%) underwent cholecystectomy only and 291 (18.2%) underwent an en bloc resection. Overall, 219 (13.7%) patients were in stage I, 400 (25%) were in stage II, 260 (16.2%) were in stage IIIA, 653 (40.8%) were in stage IIIB, and 69 (4.3%) were in stage IVB. The 5-year survival rates for patients were 82.7% for stage I, 73.4% for stage II, 31.9% for stage IIIA, 24.1% for stage IIIB, and 10% for stage IVB. Multivariate cox analysis indicated that predictors of decreased CSS included age at diagnosis >65 years, tumor size >3.2 cm, adenocarcinoma, increasing tumor spread, and lymph node involvement. Besides, chemotherapy and radiation were predictors of increased CSS. Conclusions Older age, increasing tumor size, adenocarcinoma, and advanced tumor/node stage were associated with a poorer prognosis after resection for GBC. Furthermore, patients with resectable GBC can benefit from adjuvant therapy.

Residual disease in lymph nodes has no influence on survival in patients with incidental gallbladder cancer - institution experience with literature review. Radiol Oncol 2021; 56:208-215. [PMID: 34957726 PMCID: PMC9122290 DOI: 10.2478/raon-2021-0048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Accepted: 10/27/2021] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND A better appreciation of the course and factors that influence incidental gallbladder cancer (iGBC) is needed to develop treatment strategies aimed to improve outcomes. The purpose of the study was to determine the influence of residual disease in the liver and lymph nodes on overall survival in re-resected patients with iGBC. PATIENTS AND METHODS Patients undergoing radical re-resection for iGBC from January 2012 to December 2018 were retrospectively identified. Patients with a 5-year follow-up and submitted to complete resection with stage I, II and III disease were analysed. The influence of residual disease (RD) in liver and lymph nodes on survival was assessed using the Kaplan-Meier curves. In addition, the rest of the group was assessed based on type of primary/secondary procedure, number of harvested lymph nodes and RD in liver and/or lymph nodes. RESULTS In this retrospective study 48 out of 58 (83%) patients underwent re-resection. Among the group with a 5-year follow-up (re-operation between 2012-2014), 22 patients out of 28 (79%) were re-resected. Survival analysis showed that patients with no RD in the liver and lymph nodes had statistically significant better 5-year survival than those with RD. Comparing 5-year survival rate in patients with RD in the liver or lymph nodes against no RD group, patients with RD in the liver had statistically significantly worse 5-year survival, while lymph node metastases did not show any statistically significant different in 5-year survival. Besides, a statistically significant better prognosis was found in stage II disease compared to stage III, as expected. CONCLUSIONS The most important predictors of a 5-year survival in our study were RD in liver and stage of the disease. Lymph node metastases did not have any impact on the overall 5-year survival rate.

Abstract
BACKGROUND Data supporting routine use of adjuvant chemotherapy (AC) compared to no AC (noAC) for perihilar cholangiocarcinoma (hCCA) is unclear. This study aimed to determine whether AC improves long-term survival following resection for hCCA. METHODS Patients receiving resection for hCCA followed by AC or no AC from 2010 to 2016 were identified from the National Cancer Database (NCDB). Propensity score matching (PSM) and Cox regression was performed to account for selection bias and analyze impact of AC on overall survival. RESULTS Of 924 (56%) noAC and 719 (44%) AC, 320 noAC and 320 AC patients remained after PSM. After matching, AC was associated with improved survival (median: 28.2 vs 19.9 months, p < 0.001), which remained after multivariable adjustment (HR: 0.61, CI95%: 0.50-0.75, p < 0.001). On multivariable interaction analyses, the benefit of AC over no AC persisted irrespective of nodal status: N0 (HR: 0.62, CI95%: 0.41-0.92, p = 0.019), N1 (HR: 0.52, CI95%: 0.36-0.75, p = 0.001), N2 (HR: 0.31, CI95%: 0.11-0.90, p = 0.032), Nx (HR: 0.22, CI95%: 0.09-0.55, p = 0.001) and margin status: R0 (HR: 0.74, CI95%: 0.57-0.97, p = 0.026), R1 (HR: 0.31, CI95%: 0.21-0.47, p < 0.001). Stratified analysis by nodal, margin and AC status demonstrated consistent results. CONCLUSION AC following resection for hCCA was associated with improved survival in this study, even in margin-negative and node-negative disease. These findings suggest incorporation of AC into multimodality therapy for hCCA in all cases, where appropriate.

Abstract
Vascular surgery in liver resection is a standard part of liver transplantation, but is also used in oncological liver surgery. Malignant liver tumors with vascular involvement have a poor prognosis without resection. Surgery is currently the only treatment to provide long-term survival in advanced hepatic malignancy. Even though extended liver resections are increasingly performed, vascular involvement with need of vascular reconstruction is still considered a contraindication for surgery in many institutions. However, vascular resection and reconstruction in liver surgery-despite being complex procedures-are safely performed in specialized centers. The improvements of the postoperative results with reduced postoperative morbidity and mortality are a result of rising surgical and anesthesiological experience and advancements in multimodal treatment concepts with preconditioning measures regarding liver function and systemic treatment options. This review focuses on vascular surgery in oncological liver resections. Even though many surgical techniques were developed and are also used during liver transplantation, this special procedure is not particularly covered within this review article. We provide a summary of vascular reconstruction techniques in oncological liver surgery according to the literature and present also our own experience. We aim to outline the current advances and standards in extended surgical procedures for liver tumors with vascular involvement established in specialized centers, since curative resection improves long-term survival and shifts palliative concepts to curative therapy.

Abstract
BACKGROUND Data supporting routine use of adjuvant radiotherapy (RT) compared to without RT (noRT) for gallbladder cancer (GBC) is unclear. This study aimed to determine whether RT improves long-term survival following resection for GBC. METHODS Patients receiving resection for GBC followed by RT from 2004 to 2016 were identified from the National Cancer Database (NCDB). Patients with survival <6 months were excluded to account for immortal time bias. Propensity score matching (PSM) and Cox regression was performed to account for selection bias and analyze impact of RT on overall survival. RESULTS Of 7514 (77%) noRT and 2261 (23%) RT, 2067 noRT and 2067 RT patients remained after PSM. After matching, RT was associated with improved survival (median: 26.2 vs 21.5 months, p < 0.001), which remained after multivariable adjustment (HR: 0.82, CI95%: 0.76-0.89, p < 0.001). On multivariable interaction analyses, this benefit persisted irrespective of nodal status: N0 (HR: 0.84, CI95%: 0.77-0.93), N1 (HR: 0.77, CI95%: 0.68-0.88), N2/N3 (HR: 0.56, CI95%: 0.35-0.91), margin status: R0 (HR: 0.85, CI95%: 0.78-0.93), R1 (HR: 0.78, CI95%: 0.68-0.88) and use of adjuvant chemotherapy (AC) (HR: 0.67, CI95%: 0.57-0.79). Benefit with RT were also seen in patients with T2 - T4 disease and in patients undergoing simple and extended cholecystectomy. CONCLUSION RT following resection was associated with improved survival in this study, even in margin-negative and node-negative disease. These findings may suggest addition of RT into multimodality therapy for GBC.

Abstract
BACKGROUND The 7th and 8th editions of the American Joint Committee on Cancer (AJCC) tumor (T) classification of distal cholangiocarcinoma (DCC), which are based on either layer or depth, may not accurately stratify patient survival. METHODS A total of 121 patients who underwent resection for DCC between 2002 and 2016 were analyzed. The impact of the AJCC staging system on survival was examined and a new T classification was established based on independent prognostic factors. RESULTS Regarding overall survival, the optimal depth of invasion (DOI) cut-off value (8 mm) was the only independent prognostic factor. Regarding the relapse-free survival (RFS), a DOI >8 mm, portal vein (PV) invasion, and duodenal or pancreatic invasion were independent prognostic factors. A new T classification was developed as follows: T1, no invasion of adjacent organs; T2, invasion of the duodenum or pancreas; T3, invasion >8 mm into the bile duct wall; and T4, invasion of the PV or arteries. There were no significant differences in RFS according to the 8th edition of the AJCC. However, significant differences were observed in the RFS between T1 and T2 and between T2 and T3. CONCLUSION A new T classification based on the layer and depth may be more feasible.

Kamarajah SK, Bednar F, Cho CS, Nathan H. Survival benefit with adjuvant radiotherapy after resection of distal cholangiocarcinoma: A propensity-matched National Cancer Database analysis. Cancer 2020; 127:1266-1274. [PMID: 33320344 DOI: 10.1002/cncr.33356] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Revised: 11/07/2020] [Accepted: 11/10/2020] [Indexed: 01/05/2023]
Abstract
BACKGROUND No convincing evidence for the benefit of adjuvant radiotherapy (RT) following resection of distal cholangiocarcinoma (dCCA) exists, especially for lower-risk (margin- or node-negative) disease. Hence, the association of adjuvant RT on survival after surgical resection of dCCA was compared with no adjuvant RT (noRT). METHODS Using National Cancer Database data from 2004 to 2016, patients undergoing pancreatoduodenectomy for nonmetastatic dCCA were identified. Patients with neoadjuvant RT and chemotherapy and survival <6 months were excluded. Propensity score matching was used to account for treatment-selection bias. A multivariable Cox proportional hazards model was then used to analyze the association of adjuvant RT with survival. RESULTS Of 2162 (34%) adjuvant RT and 4155 (66%) noRT patients, 1509 adjuvant RT and 1509 noRT patients remained in the cohort after matching. The rates of node-negative disease (N0), node-positive disease (N+), and unknown node status (Nx) were 39%, 51%, and 10%, respectively. After matching, adjuvant RT was associated with improved survival (median, 29.3 vs 26.8 months; P < .001), which remained after multivariable adjustment (HR, 0.86; 95% CI, 0.80-0.93; P < .001). Multivariable interaction analyses showed this benefit was seen irrespective of nodal status (N0: HR, 0.77; 95% CI, 0.66-0.89; P < .001; N+: HR, 0.79; 95% CI, 0.71-0.89; P < .001) and margin status (R0: HR, 0.58; 95% CI, 0.50-0.67; P < .001; R1: HR, 0.87; 95% CI, 0.78-0.96; P = .007). Stratified analyses by nodal and margin status demonstrated consistent results. CONCLUSIONS Adjuvant RT after dCCA resection was associated with a survival benefit in patients, even in patients with margin- or node-negative resections. Adjuvant RT should be considered routinely irrespective of margin and nodal status after resection for dCCA. LAY SUMMARY Adjuvant radiotherapy after resection of distal cholangiocarcinoma was associated with a survival benefit in patients, even in patients with margin-negative or node-negative resections. Adjuvant radiotherapy should be considered routinely irrespective of margin and nodal status after resection of distal cholangiocarcinoma.

Abstract
Background Although pancreaticoduodenectomy with vein resection (PDVR) is widely performed in selected patients with indications, its benefits remain controversial. In this meta-analysis, we evaluate the safety and efficacy of PDVR in comparison to standard pancreaticoduodenectomy (PD). Methods We searched PubMed, Embase, and Cochrane as well as the Chinese National Knowledge Infrastructure, Weipu, and Wanfang databases for studies that evaluate the value of PVDR. The data of the patients who underwent PD or PDVR were analyzed using Review Manager and STATA software. Results In comparison with the PD group, the PDVR group had a lower R0 resection rate and higher rates of complications such as biliary fistula, reoperation rate, delayed gastric emptying, cardiopulmonary abnormalities, hemorrhage, in-hospital mortality, 30-day mortality. The blood loss, duration of operation, total hospital stay is higher in PDVR group. Conclusions Compared to standard PD, PDVR was associated with a greater risk of some specific complications and increase the mortality rate, total hospital stay time, combine with vein resection have a lower R0 resection rate. Therefore, combine with vascular resection for pancreatic cancer needs to be carefully selected by the surgeon.

Abstract
Pancreatic cancer is one of the most aggressive and lethal malignancies with a dismal prognosis and survival. The curative effects of venous resection (VR) in pancreatic cancer remain controversial. A systematic literature search was performed in PubMed, Embase and the Cochrane Library. The overall postoperative complications, perioperative mortality, histopathology, and long-term survival were compared between patients undergoing pancreatectomy combined with (VR+ group) or without (VR- group) VR. Forty-one studies were included in the systematic review. Pancreatectomy combined with VR required longer operation time and led to increased perioperative blood loss, whereas postoperative complications were similar. Patients in the VR+ group showed larger tumors and reduced R0 rates. Regarding long-term survival, patients with VR+ seemed to have impaired 1-, 3-, and 5-year survival. Based on our results, VR in pancreatic cancer is a safe and feasible procedure. Given the fact that patients have miserable outcomes and survival in the palliative setting alone, extended resection including VR is required for the purpose of achieving radical resection.

Abstract
BACKGROUND Morbidity and mortality after hepatectomy for perihilar cholangiocarcinoma are known to be high. However, reported postoperative outcomes vary, with notable differences between Western and Asian series. We aimed to determine morbidity and mortality rates after major hepatectomy in patients with perihilar cholangiocarcinoma and assess differences in outcome regarding geographic location and hospital volume. METHODS A systematic review was performed by searching the MEDLINE and EMBASE databases through November 20, 2017. Risk of bias was assessed and meta-analysis and metaregression were performed using a random effects model. RESULTS A total of 51 studies were included, representing 4,634 patients. Pooled 30-day and 90-day mortality were 5% (95% CI 3%-6%) and 9% (95% CI 6%-12%), respectively. Pooled overall morbidity and severe morbidity were 57% (95% CI 50%-64%) and 40% (95% CI 34%-47%), respectively. Western studies compared with Asian studies had a significantly higher 30-day mortality, 90-day mortality, and overall morbidity: 8% versus 2% (P < .001), 12% versus 3% (P < .001), and 63% versus 54% (P = .048), respectively. This effect on mortality remained significant after correcting for hospital volume. Univariate metaregression analysis showed no influence of hospital volume on mortality or morbidity, but when corrected for geographic location, higher hospital volume was associated with higher severe morbidity (P = .039). CONCLUSION Morbidity and mortality rates after major hepatectomy for perihilar cholangiocarcinoma are high. The Western series showed a higher mortality compared with the Asian series, even when corrected for hospital volume. Standardized reporting of outcomes is necessary. Underlying causes for differences in outcomes between Asian and Western centers, such as differences in treatment strategies, should be further analyzed.

Abstract
Background Major vascular reconstruction during a pancreaticoduodenectomy (PD), also known as a Whipple procedure, leads to controversial postoperative outcomes compared to conventional Whipple. Discussion with the patient regarding postoperative expectations is a crucial component of holistic surgical healthcare. The aim of this study was to report our 8-year experience of Whipple procedures involving vascular reconstruction and to review relevant literature to further evaluate expectant outcomes, therefore leading to more accurate discussion. Methods A retrospective review of patients undergoing Whipple procedures from January 2010, through December 2017 was performed. Patch, graft, and primary anastomosis during Whipple procedures were considered major vascular reconstruction. Literature on the current understanding of the outcomes associated with vascular reconstruction during Whipple procedures was reviewed. Results Twenty-nine from a total of 405 patients that met inclusion criteria had a Whipple procedure that involved major vascular reconstruction. Twelve patients were male and 17 were female (mean age, 65.2 years). Median hospital and intensive care unit (ICU) stay [range] of patients with vascular reconstruction was 12 [5-92] days and 3 [0-59] days, respectively. Thirty-day survival and 1-year survival of patients with vascular reconstruction was 93.1% and 55.2%, respectively, compared to non-vascular reconstruction patients 96.0% and 83.5%, respectively (P=0.35, P<0.001). Ninety-day readmission for vascular reconstruction patients was 31.0% compared to 14.6% in non-vascular reconstruction patients (P=0.03). The 1-year survival of those who had patch reconstruction, graft reconstruction, and primary anastomosis was 50.0%, 62.5%, 53.8%, respectively. Conclusions Compared to conventional Whipple procedures, those requiring major vascular reconstruction are associated with decreased survival. When vascular reconstruction is a valid option patients should be well aware of the associated outcomes.

Abstract
AIM To investigate the perioperative management and outcome of patients undergoing abdominal surgery with additional vascular (comorbid) alterations for internal quality assurance of the clinical results. METHODS Over a defined study period all consecutive cases of the aforementioned profile were documented and retrospectively analyzed as part of an ongoing prospective monocentric observational study to reflect the daily surgical practice. RESULTS Over 10 years (from January 1999 to December 2008), a total of 113 cases were registered. Pancreas resection including vascular reconstruction showed the highest percentage (30.1%). Within the target patient groups, similar outcome data were found compared with international reports. An exception was in the case of mesenteric ischemia, where open surgery was more frequently used in comparison to the study situation (included together were patients treated by surgery and interventions). The majority of vascular alterations during the postoperative course and iatrogenic lesions occurred following pancreas resection. In the therapeutic profile there are two particularly important measures, namely open surgery on one hand and image-guided radiology as well as endoscopy on the other hand. The majority of patients with a rare visceral artery aneurysm (considerable potential for rupture or erosion) were more frequently treated with image-guided interventional radiology versus open surgery. This conforms to the current well-established sequential patient (individual), results, and, in particular, risk-adapted staged treatment approach. CONCLUSION Additional vascular surgical treatment of problematic situations during abdominal surgery or in emergency cases is not daily routine; however, it is a challenging field including a considerable potential for complications (morbidity) and definitely mortality. This requires an experienced surgeon with high expertise, if possible in a center for vascular medicine.

Abstract
BACKGROUND Little is known about the value of portal vein (PV) resection in distal cholangiocarcinoma. The aim of this study was to evaluate the clinical significance of PV resection in distal cholangiocarcinoma. METHODS Patients who underwent pancreatoduodenectomy (PD) for distal cholangiocarcinoma between 2001 and 2010 at one of 31 hospitals in Japan were reviewed retrospectively with special attention to PV resection. Short- and long-term outcomes were evaluated. RESULTS In the study interval, 453 consecutive patients with distal cholangiocarcinoma underwent PD, of whom 31 (6·8 per cent) had combined PV resection. The duration of surgery (510 versus 427 min; P = 0·005) and incidence of blood transfusion (48 versus 30·7 per cent; P = 0·042) were greater in patients who had PV resection than in those who did not. Postoperative morbidity and mortality were no different in the two groups. Several indices of tumour progression, including high T classification, lymphatic invasion, perineural invasion, pancreatic invasion and lymph node metastasis, were more common in patients who had PV resection. Consequently, the incidence of R1/2 resection was higher in this group (32 versus 11·8 per cent; P = 0·004). Survival among the 31 patients with PV resection was worse than that for the 422 patients without PV resection (15 versus 42·4 per cent at 5 years; P < 0·001). Multivariable analyses revealed that age, blood loss, histological grade, perineural invasion, pancreatic invasion, lymph node metastasis and surgical margin were independent risk factors for overall survival. PV resection was not an independent risk factor. CONCLUSION PV invasion in distal cholangiocarcinoma is associated with locally advanced disease and several negative prognostic factors. Survival for patients who have PV resection is poor even after curative resection.

Abstract
Extension of pancreatic adenocarcinoma into adjacent vasculature often necessitates resection of the portal vein (PV) and or superior mesenteric vein (SMV) during pancreaticoduodenectomy (PD). Our study describes the surgical technique and results of PV/SMV resection in pancreatic adenocarcinoma patients. Between January 2008 and October 2013, 252 patients underwent PD for pancreatic malignancy. A total of 42 PV/SMV resections were performed (28 men, 14 women). Patients were categorized into 2 groups according to the degree of invasion into the portal vein wall: Group A (n = 16), extended compression of the portal vein wall by the surrounding carcinoma without true invasion, and Group B (n = 26), true invasion including intramural and transmural invasion. Morbidity of the 42 patients was 35%; there was no operative mortality, and overall 1-, 3-, and 5-year survival rates were 60%, 21%, and 12%, respectively. No differences in tumor size, margin positivity, nodal positivity, or survival rates were observed between groups. Resection of the PV/SMV is safe and does not increase morbidity or mortality. Tumor involvement of the PV/SMV is not associated with histopathologic signs that are predictive of a poor prognosis. The “artery first” approach should be considered as a means to facilitate safe venous resection and reconstruction.

Abstract
With surgery for hepatic malignancy, there are poor options for chemotherapy; many patients are deemed unresectable because of vascular involvement or location of tumors. Over the past few decades, advances in surgical technique have allowed resection of these tumors with vascular reconstruction to achieve negative margins and improve chances for survival. This article reviews those reconstruction techniques and outcomes in detail, including in situ perfusion and ex vivo liver surgery, and provides a discussion of implications and operative planning for patients with hepatic malignancy in order to provide surgeons with better understanding of these complicated operations.

Abstract
Pancreatic ductal adenocarcinoma carries a poor prognosis with annual deaths almost matching the reported incidence rates. Surgical resection offers the only potential cure. Yet, even among patients that undergo tumor resection, recurrence rates are high and long-term survival is scarce. Various tumor-related factors have been identified as predictors of survival after potentially curative resection. These factors include tumor size, lymph node disease, tumor grade, vascular invasion, perineural invasion and surgical resection margin. This article will re-evaluate the importance of these factors based on recent publications on the topic, with potential implications for treatment and outcome in patients with pancreatic cancer.

Abstract
PURPOSE The aim of this study was to assess the efficacy of combined resection and reconstruction (CRR) of the hepatic artery (HA) in surgery for hilar cholangiocarcinoma (HC). MATERIALS AND METHOD Among 172 patients who underwent surgical resection for HC, the following three groups were defined according to the type of vascular reconstruction: VR(-) group, in which neither CRR of the portal vein (PV) nor HA was performed (n = 74); VR-PV group, in which only CRR of the PV was required (n = 54); and VR-A group, in which CRR of the HA was performed either with or without CRR of the PV (n = 44). Clinicopathological variables and clinical outcomes were compared among the three groups. RESULTS Although the VR-A group showed significantly more advanced disease than other groups, the R0 resection rate was comparable among the three groups (VR(-), 74 %; VR-PV, 80 %; VR-A, 80 %). The 5-year disease-specific survival rate was also comparable among the three groups (VR(-), 45.6 %; VR-PV, 51.2 %; VR-A, 22.3 %), but tended to be worse in the VR-A group than in the other groups. A similar trend was observed in morbidity rate. Lymph node metastasis was more frequent in the VR-A group (59 %) than in the other groups (VR(-), 33.8 %; VR-PV, 50 %). In the VR-A group, lymph node metastasis (p = 0.004) and adjuvant chemotherapy (p = 0.006) were determined to represent independent prognostic factors for survival according to multivariate analysis. CONCLUSION CRR of the HA was considered efficacious in selected patients; however, long-term outcomes of the VR-A group seem unsatisfactory. Treatments additional to surgery may be necessary in cases requiring CRR of the HA.

Br J Surg 2015; 103:179-91. [PMID: 26663252 DOI: 10.1002/bjs.9969] [Citation(s) in RCA: 121] [Impact Index Per Article: 13.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2015] [Revised: 08/27/2015] [Accepted: 09/15/2015] [Indexed: 01/06/2023]
Abstract
BACKGROUND Pancreatic ductal adenocarcinoma has a poor prognosis without surgery. No standard treatment has yet been accepted for patients with portal-superior mesenteric vein (PV-SMV) infiltration. The present meta-analysis aimed to compare the results of pancreatic resection with PV-SMV resection for suspected infiltration with the results of surgery without PV-SMV resection. METHODS A systematic search was performed of PubMed, Embase and the Cochrane Library in accordance with PRISMA guidelines from the time of inception to 2013. The inclusion criteria were comparative studies including patients who underwent pancreatic resection with or without PV-SMV resection. One, 3- and 5-year survival were the primary outcomes. RESULTS Twenty-seven studies were identified involving a total of 9005 patients (1587 in PV-SMV resection group). Patients undergoing PV-SMV resection had an increased risk of postoperative mortality (risk difference (RD) 0.01, 95 per cent c.i. 0.00 to 0.03; P = 0.2) and of R1/R2 resection (RD 0.09, 0.06 to 0.13; P < 0.001) compared with those undergoing standard surgery. One-, 3- and 5-year survival were worse in the PV-SMV resection group: hazard ratio 1.23 (95 per cent c.i. 1.07 to 1.43; P = 0.005), 1.48 (1.14 to 1.91; P = 0.004) and 3.18 (1.95 to 5.19; P < 0.001) respectively. Median overall survival was 14.3 months for patients undergoing pancreatic resection with PV-SMV resection and 19.5 months for those without vein resection (P = 0.063). Neoadjuvant therapies recently showed promising results. CONCLUSION This meta-analysis showed increased postoperative mortality, higher rates of non-radical surgery and worse survival after pancreatic resection with PV-SMV resection. This may be related to more advanced disease in this group.

Abstract
BACKGROUND The need for an early determination of resectability and before an irreversible step is taken during pancreatoduodenectomy promoted the development of an 'artery first approach' (AFA). The aim of this study was to review the current evidence related to this approach, with particular reference to margins and survival. METHODS An electronic search was performed in MEDLINE, EMBASE and PubMed databases from 1960 to 2015 using both subject headings (MeSH) and truncated word searches to identify all published related articles to this topic. RESULTS Six different AFAs have been published. Four studies evaluated the impact of AFA on perioperative outcomes and survival. Three studies showed no difference in the perioperative outcomes, margin status, lymph node yield and survival while one study showed improved margin status and survival comparing AFA with standard resection. CONCLUSION The current evidence regarding the benefits of AFA in relation to decreasing margin positivity or increasing survival is sparse. Further larger studies and randomized controlled trails are needed to ascertain the benefits of AFA.

Abstract
An American Hepato-Pancreato-Biliary Association (AHPBA)-sponsored consensus meeting of expert panellists was convened on 15 January 2014 to review current evidence on the management of gallbladder carcinoma in order to establish practice guidelines. In summary, within high incidence areas, the assessment of routine gallbladder specimens should include the microscopic evaluation of a minimum of three sections and the cystic duct margin; specimens with dysplasia or proven cancer should be extensively sampled. Provided the patient is medically fit for surgery, data support the resection of all gallbladder polyps of >1.0 cm in diameter and those with imaging evidence of vascular stalks. The minimum staging evaluation of patients with suspected or proven gallbladder cancer includes contrasted cross-sectional imaging and diagnostic laparoscopy. Adequate lymphadenectomy includes assessment of any suspicious regional nodes, evaluation of the aortocaval nodal basin, and a goal recovery of at least six nodes. Patients with confirmed metastases to N2 nodal stations do not benefit from radical resection and should receive systemic and/or palliative treatments. Primary resection of patients with early T-stage (T1b-2) disease should include en bloc resection of adjacent liver parenchyma. Patients with T1b, T2 or T3 disease that is incidentally identified in a cholecystectomy specimen should undergo re-resection unless this is contraindicated by advanced disease or poor performance status. Re-resection should include complete portal lymphadenectomy and bile duct resection only when needed to achieve a negative margin (R0) resection. Patients with preoperatively staged T3 or T4 N1 disease should be considered for clinical trials of neoadjuvant chemotherapy. Following R0 resection of T2-4 disease in N1 gallbladder cancer, patients should be considered for adjuvant systemic chemotherapy and/or chemoradiotherapy.

Abstract
The gallbladder neck cancer and perihilar cholangiocarcinoma present as painless progressive surgical obstructive jaundice. Sometimes it becomes difficult to differentiate between them even on cross-sectional imaging studies including computed tomography and magnetic resonance imaging. Staging laparoscopy and positron emission tomography may be useful in detecting metastases in gallbladder neck cancer, but are not recommended in perihilar cholangiocarcinoma. Most patients with gallbladder neck cancer and perihilar cholangiocarcinoma require preoperative biliary drainage. The differentiation is, however, important because their behavior and prognosis are totally different. Gallbladder neck cancer is biologically aggressive, thus long-term surviver are rare even after major resection. On the other hand, perihilar cholangiocarcinoma is often less aggressive and major proceduresresections are justified. Gallbladder neck cancer and perihilar cholangiocarcinoma, though not siblings, they tend to look alike sometimes.

Abstract
BACKGROUND The Japanese Society of Hepato-Biliary-Pancreatic Surgery launched the clinical practice guidelines for the management of biliary tract and ampullary carcinomas in 2008. Novel treatment modalities and handling of clinical issues have been proposed after the publication. New approaches for editing clinical guidelines, such as the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system, also have been introduced for better and clearer grading of recommendations. METHODS Clinical questions (CQs) were proposed in seven topics. Recommendation, grade of recommendation and statement for each CQ were discussed and finalized by evidence-based approach. Recommendation was graded to grade 1 (strong) and 2 (weak) according to the concept of GRADE system. RESULTS The 29 CQs covered seven topics: (1) prophylactic treatment, (2) diagnosis, (3) biliary drainage, (4) surgical treatment, (5) chemotherapy, (6) radiation therapy, and (7) pathology. In 27 CQs, 19 recommendations were rated strong and 11 recommendations weak. Each CQ included the statement of how the recommendation was graded. CONCLUSIONS This guideline provides recommendation for important clinical aspects based on evidence. Future collaboration with cancer registry will be a key for assessment of the guidelines and establishment of new evidence. Free full-text articles and a mobile application of this guideline are available via http://www.jshbps.jp/en/guideline/biliary-tract2.html.

Abstract
BACKGROUND The fate of the portal vein (PV) after pancreatoduodenectomy, especially its long-term patency and associated complications, has received little attention. The aim of this study was to explore the long-term patency rate of the PV after pancreatoduodenectomy, focusing on risk factors for PV stenosis/occlusion and associated complications. METHODS Serial CT images of patients who underwent pancreatoduodenectomy for periampullary cancer between January 2000 and June 2012 in a single institution were evaluated for PV stenosis or occlusion. RESULTS A total of 826 patients were enrolled. The PV stenosis/occlusion rate after pancreatoduodenectomy was 19.6 per cent and the 5-year patency rate 69.9 per cent. The most frequent cause of PV stenosis/occlusion was local recurrence followed by postoperative change and PV thrombosis. Patients who underwent PV resection had a higher PV stenosis/occlusion rate than those who did not (51 versus 17.4 per cent; P < 0.001). The 3-year patency rate was highest in patients with cancer of the ampulla of Vater and lowest in patients with pancreatic cancer (91.9 versus 55.5 per cent respectively; P < 0.001). Multivariable analysis showed that risk factors for PV stenosis/occlusion included primary tumour location, chemoradiotherapy and PV resection. PV stenosis or occlusion without disease recurrence was observed in 17.3 per cent of the patients. PV resection and grade B or C pancreatic fistula were independent risk factors for PV stenosis/occlusion. Among 162 patients with PV stenosis or occlusion, five (3.1 per cent) had fatal recurrent gastrointestinal bleeding. CONCLUSION PV stenosis or occlusion is common after pancreatoduodenectomy, particularly if the PV has been resected and/or chemoradiotherapy was given after surgery. Although recurrence is the most frequent cause of PV stenosis/occlusion, this complication is found in a significant proportion of patients without disease recurrence.

Abstract
BACKGROUND Pancreaticoduodenectomy combined with portal-superior mesenteric vein synchronous resection for cancer remains a hot debate topic. The present study used meta-analytical technique to provide update information and an evidence-based evaluation on both the perioperative benefit and long-term survival. METHODS A meta-analysis was performed to evaluate studies comparing venous resection (VR) versus without venous resection (WVR) groups. 22 retrospective studies including 2890 patients were eligible for an analysis of perioperative morbidity, mortality, and long-term survival. Furthermore, subgroup analysis was made according to histopathology and resection margin status respectively for the purpose of survival assessment. RESULTS There was no difference in perioperative morbidity, mortality and 1-year, 3-year survival between two groups, but showed differences in median tumor size (P < 0.001), R0 resection rate (P < 0.001), lymph node metastasis (P = 0.03), pancreatic fistula (P = 0.01), and 5-year survival (P = 0.03). In subgroup analysis, patients in venous resection group received R0 resection had a significantly better survival comparing with who received R1 resection both at 2-year (P < 0.001) and 5-year (P = 0.00002). In histopathology subgroup, patients in venous resection groups who had true tumor infiltration had a significantly bad survival comparing with whom only with inflammation pathology. CONCLUSION Pancreaticoduodenectomy combined with venous resection can achieve equal perioperative morbidity and mortality as standard resection. However, in order to obtain an optimal survival outcome, surgeons should make an R0 resection as far as possible, especially in cases need synchronous venous resection.

Abstract
Primary and secondary hepatic malignancies, including hepatocellular cancer, cholangiocarcinoma and metastatic disease from colorectal cancer continue to increase in incidence worldwide, and remain diseases with a high mortality. Liver resection, with negative margins, is associated with improved survival and better quality of life over nonoperative treatment. As liver resection continues to evolve, aggressive centers are increasingly using vascular resection and reconstruction to achieve negative margins and improve outcomes. As these resections become more common, the morbidity and mortality associated with these complex surgical procedures is decreasing. Currently, resections of the portal vein are becoming routine in major liver and pancreatic resections, and experience with hepatic artery, hepatic vein and inferior vena cava resections is increasing. This review paper looks at the current indications, techniques and outcomes for major vascular resection in hepatic malignancy.

Abstract
Objective The aim of this study was to present the therapeutic outcome of patients with locally advanced pancreatic cancer treated with pancreatoduodenectomy combined with vascular resection and reconstruction in addition to highlighting the mortality/morbidity and main prognostic factors associated with this treatment. Materials and Methods We retrospectively analyzed the clinical and pathological data of a total of 566 pancreatic cancer patients who were treated with PD from five teaching hospitals during the period of December 2006–December 2011. This study included 119 (21.0%) patients treated with PD combined with vascular resection and reconstruction. We performed a detailed statistical analysis of various factors, including postoperative complications, operative mortality, survival rate, operative time, pathological type, and lymph node metastasis. Results The median survival time of the 119 cases that received PD combined with vascular resection was 13.3 months, and the 1-, 2-, and 3-year survival rates were 30.3%, 14.1%, and 8.1%, respectively. The postoperative complication incidence was 23.5%, and the mortality rate was 6.7%. For the combined vascular resection group, complications occurred in 28 cases (23.5%). For the group without vascular resection, complications occurred in 37 cases (8.2%). There was significant difference between the two groups (p = 0.001). The degree of tumor differentiation and the occurrence of complications after surgery were independent prognostic factors that determined the patients’ long-term survival. Conclusions Compared with PD without vascular resection, PD combined with vascular resection and reconstruction increased the incidence of postoperative complications. However, PD combined with vascular resection and reconstruction could achieve the complete removal of tumors without significantly increasing the mortality rate, and the median survival time was higher than that of patients who underwent palliative treatment. In addition, the two independent factors affecting the postoperative survival time were the degree of tumor differentiation and the presence or absence of postoperative complications.

Vein involvement during pancreaticoduodenectomy: is there a need for redefinition of "borderline resectable disease"? J Gastrointest Surg 2013; 17:1209-17; discussion 1217.

Abstract
INTRODUCTION Current National Comprehensive Cancer Network guidelines recommend neoadjuvant therapy for borderline resectable pancreatic adenocarcinoma to increase the likelihood of achieving R0 resection. A consensus has not been reached on the degree of venous involvement that constitutes borderline resectability. This study compares the outcome of patients who underwent pancreaticoduodenectomy with or without vein resection without neoadjuvant therapy. METHODS A multi-institutional database of patients who underwent pancreaticoduodenectomy was reviewed. Patients who required vein resection due to gross vein involvement by tumor were compared to those without evidence of vein involvement. RESULTS Of 492 patients undergoing pancreaticoduodenectomy, 70 (14 %) had vein resection and 422 (86 %) did not. There was no difference in R0 resection (66 vs. 75 %, p = NS). On multivariate analysis, vein involvement was not predictive of disease-free or overall survival. CONCLUSION This is the largest modern series examining patients with or without isolated vein involvement by pancreas cancer, none of whom received neoadjuvant therapy. Oncological outcome was not different between the two groups. These data suggest that up-front surgical resection is an appropriate option and call into question the inclusion of isolated vein involvement in the definition of "borderline resectable disease."

Abstract
INTRODUCTION In pancreatic adenocarcinoma (PA), a margin negative resection (R0) is critical for long-term survival. BACKGROUND Although pancreaticoduodenectomy (PD) with en-bloc portal vein/superior mesenteric vein (PV/SMV) resection is used in patients with venous involvement by tumor, its utility in patients with no venous involvement is unknown. This study examines survival in patients with no venous involvement who had PD with PV/SMV resection. METHODS From 2000 to 2010, 34 patients had PD with PV/SMV resection for resectable PA on preoperative staging. Fifteen patients (44%) had histological venous involvement and 19 (56%) had no histological involvement (-PV/SMV group). We matched 1:1 the -PV/SMV group (n = 19) with 19 contemporaneous PA patients who had a standard PD (control group) for age, tumor stage, tumor size, lymph node invasion, lymph node ratio, perineural invasion, margins status, and carbohydrate antigen 19-9 (CA 19-9) levels. RESULTS No differences were noted between the -PV/SMV group (n = 19) and the matched control group (n = 19) in morbidity, mortality, reoperation rate, or length of hospital stay. Median survival (42 months vs. 22 months, P = 0.02) and overall 3-year survival (60% vs. 31%, P = 0.03) were significantly longer in the -PV/SMV group compared with the control group. CONCLUSIONS Patients with PA and no venous involvement who had PD with PV/SMV resection had a significantly longer overall survival than patients in a matched control group who had PD without venous resection.

Abstract
BACKGROUND Several single-center reports suggest that vascular resection (VR) during pancreaticoduodenectomy (PD) for patients with pancreatic adenocarcinoma is feasible without affecting early postoperative mortality or morbidity. Our objective is to review the outcomes associated with VR during PD using a large multicenter data source. METHODS A retrospective cohort analysis was performed using the National Surgical Quality Improvement Program Participant User Files for 2005-2009. All patients undergoing PD for a postoperative diagnosis of malignant neoplasm of the pancreas were included. Forward stepwise multivariate regression analysis was used to determine the association between VR during PD and 30-day postoperative mortality and morbidity after adjustment for patient demographics and comorbidities. RESULTS 3,582 patients were included for analysis, 281 (7.8 %) of whom underwent VR during PD. VR during PD was associated with significantly greater risk-adjusted 30-day postoperative mortality [5.7 % with VR versus 2.9 % without VR, adjusted odds ratio (AOR) 2.1, 95 % confidence interval (CI) 1.22-3.73, P = 0.008] and overall morbidity (39.9 % with VR versus 33.3 % without VR, AOR 1.36, 95 % CI 1.05-1.75, P = 0.02). There was no significant difference in risk-adjusted postoperative mortality or morbidity between those patients undergoing VR by the primary surgical team versus those patients undergoing VR by a vascular surgical team. CONCLUSIONS Contrary to the findings of several previously published single-center analyses, the current study demonstrates increased 30-day postoperative morbidity and mortality in PD with VR when compared with PD alone.

Abstract
BACKGROUND Pancreatectomy combined with superior mesenteric vein-portal vein resection (VR) for pancreatic cancer remains a matter of debate. The present study is a meta-analysis of the available evidence. METHODS Articles published until end of March 2011, comparing the results of pancreatic resections with VR versus without VR, were searched. Pooled odds ratios (OR) and weighted mean differences (WMD; with 95% Confidence Intervals [95% CI]) were calculated using either the fixed effects model or the random effects model. RESULTS Nineteen nonrandomized studies met the inclusion criteria, comprising 2,247 patients. There was no difference in perioperative morbidity (OR: 0.95; 95% CI: 0.74-1.21; P = 0.67), mortality (OR: 1.19; 95% CI: 0.73-1.96; P = 0.48), or 5-year overall survival (OR: 0.57; 95% CI: 0.32-1.02; P = 0.06) between patients with VR and those without VR. CONCLUSIONS Pancreatectomy combined with VR resection for pancreatic cancer is justified because it can result in good perioperative outcome and long-term survival comparable to that obtained with standard resection. Owing to the selection bias and low level of clinical evidence available so far, the results should be interpreted with caution.

Histologic tumor involvement of superior mesenteric vein/portal vein predicts poor prognosis in patients with stage II pancreatic adenocarcinoma treated with neoadjuvant chemoradiation. Cancer 2011; 118:3801-11. [PMID: 22180096 DOI: 10.1002/cncr.26717] [Citation(s) in RCA: 54] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2011] [Revised: 08/25/2011] [Accepted: 10/18/2011] [Indexed: 12/11/2022]
Abstract
BACKGROUND Studies have shown that superior mesenteric vein (SMV)/portal vein (PV) resection with pancreaticoduodenectomy (PD) is safe and feasible for patient with pancreatic adenocarcinoma (PAC). However, the prognostic significance of tumor involvement of the resected vein in patients who received neoadjuvant therapy is unclear. METHODS The authors evaluated 225 consecutive patients with stage II PAC who received neoadjuvant therapy and PD with or without SMV/PV resection. The resected SMV/PV was entirely submitted for histologic assessment and reviewed in all cases. Tumor involvement of the SMV/PV was correlated with clinicopathologic features and survival. RESULTS Among the 225 patients, SMV/PV resection was performed in 85 patients. Histologic tumor involvement of the resected SMV/PV was identified in 57 patients. Histologic tumor involvement of the SMV/PV was associated with larger tumor size, higher rates of positive margin, and local/distant recurrence. By multivariate analysis, tumor involvement of the SMV/PV was an independent predictor of both disease-free survival (DFS) and overall survival (OS). However, addition of venous resection to PD itself had no impact on either DFS or OS compared with those with PD alone. CONCLUSIONS Histologic tumor involvement of the SMV/PV is an independent predictor of both DFS and OS in patients with stage II PAC treated with neoadjuvant therapy and PD. Complete histologic evaluation of the resected SMV/PV is important for the prognosis in patients with PAC who received neoadjuvant therapy and PD.

Abstract
AIMS Gallbladder carcinoma usually presents late with advanced disease. It develops in an anatomically complex area. Consideration is given to resection of relevant local structures with respect to outcome. METHODS A comprehensive literature review was performed, searching Medline for articles published since 2000, using the MeSH heading of 'gallbladder cancer' and 'surgery'. Abstracts were reviewed and articles retrieved if the main focus of the article centred on the surgical management of gallbladder carcinoma. OBSERVATIONS Hepatic resection is advocated and tailored to pathological T stage. Lymph node dissection and bile duct resection, as well as en bloc resection of other viscera, remain areas of controversy. CONCLUSIONS Eastern and Western practice standards of care differ, but hepatic resection with some lymph node dissection is present in both approaches. Philosophy regarding aggression with respect to en bloc resection of adjacent organs and actual extent of lymphatic resection remains disparate.

Does portal-superior mesenteric vein invasion still indicate irresectability for pancreatic carcinoma? Ann Surg Oncol 2009; 16:817-25. [PMID: 19156463 DOI: 10.1245/s10434-008-0281-8] [Citation(s) in RCA: 103] [Impact Index Per Article: 6.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2008] [Revised: 11/18/2008] [Accepted: 11/18/2008] [Indexed: 12/11/2022]
Abstract
BACKGROUND Pancreatic carcinoma frequently infiltrates the portal vein or the superior mesenteric vein; pancreatectomy combined with portal vein/superior mesenteric vein resection represents a potentially curative treatment in these cases but is still a controversial procedure. METHODS After performing a computerized Medline search, 12 series published during the last 8 years were selected, enrolling 399 patients who underwent pancreatectomy combined with portal vein/superior mesenteric vein resection for pancreatic carcinoma. Data were examined for information about indications, operation, adjuvant therapies, histopathology of resected specimens, perioperative results, and survival. Also, previous literature regarding the issue was extensively reviewed. RESULTS Operative mortality and postoperative complication rates ranged from 0 to 7.7% and 16.7% to 54%, respectively. Median survival varied from 13 to 22 months; 5-year survival rate ranged from 9% to 18%. CONCLUSIONS The current literature suggests that portal vein/superior mesenteric vein resection combined with pancreatectomy is a safe and feasible procedure that increases the number of patients who undergo curative resection and, therefore, provides important survival benefits to selected groups of patients. This procedure should always be considered in case of suspected tumor infiltration of portal/superior mesenteric vein to achieve clear resection margins, in the absence of other contraindications for resection.
