Background
Current guidelines recommend adjuvant chemotherapy for resected pancreatic adenocarcinoma (PDAC). However, no studies have addressed its survival benefit for stage I patients as they comprise <10% of PDAC.Methods
Using the NCDB 2006–2012, resected PDAC patients with stage I disease who received adjuvant therapy (chemotherapy or chemoradiation) were analyzed. Factors associated with overall survival (OS) were identified.Results
3909 patients with resected stage IA or IB PDAC were identified. Median OS was 60.3 months (mo) for stage IA and 36.9 mo for IB. 45.5% received adjuvant chemotherapy; 19.9% received adjuvant chemoradiation. There was OS benefit for both stage IA/IB patients with adjuvant chemotherapy (HR = 0.73 and 0.76 for IA and IB, respectively, p = 0.002 and <0.001). For patients with Stage IA disease (n = 1,477, 37.8%), age ≥70 (p < 0.001), higher grade (p < 0.001), ≤10 lymph nodes examined (p = 0.008), positive margins (p < 0.001), and receipt of adjuvant chemoradiation (p = 0.002) were associated with worse OS. For stage IB patients (n = 2,432, 62.2%), similar associations were observed with the exception of adjuvant chemoradiation whereby there was no significant association (p = 0.35).Conclusion
Adjuvant chemotherapy was associated with an OS benefit for patients with stage I PDAC; adjuvant chemoradiation was either of no benefit or associated with worse OS. 相似文献2.

Background
Studies comparing microwave ablation (MWA) and liver resection are lacking. This study evaluates the survival of patients with hepatocellular carcinoma (HCC) treated with liver resection or MWA and the role of Albumin-Bilirubin (ALBI) score in patient selection for treatments.Methods
This is a retrospective analysis of patients who received curative liver resection or MWA for HCC. Propensity score matching was used at a 1:1 ratio. The value of ALBI grade for patient selection was evaluated. Overall and disease-free survival were compared between two groups.Results
Of the 442 patients underwent MWA or liver resection for HCC during the study period, 63 patients received MWA and 379 patients received liver resection. Propensity scoring matching analysis resulted in 63 matched pairs for further analysis. Subgroup analysis according to the ALBI grade was performed. Liver resection offered better overall and disease-free survivals in patients with ALBI grade 1. MWA provided a significantly better overall survival (p = 0.025) and a trend towards better disease-free survival (p = 0.39) in patients with ALBI grade 2 or 3.Conclusions
Liver resection offered superior disease-free survival to MWA in patients with HCC. The ALBI grade could identify patients with worse liver function who might gain survival advantage from MWA. 相似文献3.

Objective
This was a systematic review and meta-analysis to compare outcomes between patients undergoing simultaneous or delayed hepatectomy for synchronous colorectal liver metastases.Background
The optimal strategy for treating liver disease among patients with resectable synchronous colorectal liver metastases (CRLM) is unclear. Simultaneous resection of primary tumour and liver metastases may improve patient experience by reducing the number of interventions. However, there are concerns of increased morbidity compared to delayed resections.Methods
A systematic literature search was performed using EMBASE, Medline, Cochrane library and Google scholar databases. Meta-analyses were performed using both random-effects and fixed-effect models. Publication and patient selection bias were assessed with funnel plots and sensitivity analysis.Results
Thirty studies including 5300 patients were identified. There were no statistically significant differences in parameters relating to safety and efficacy between the simultaneous and delayed hepatectomy cohorts. Patients undergoing delayed surgery were more likely to have bilobar disease or undergo major hepatectomy. The average length of hospital stay was six days shorter with simultaneous approach [MD = ?6.27 (95% CI: ?8.20, ?4.34), p < 0.001]. Long term survival was similar for the two approaches [HR = 0.97 (95%CI: 0.88, 1.08), p = 0.601].Conclusion
In selected patients, simultaneous resection of liver metastases with colorectal resection is associated with shorter hospital stay compared to delayed resections, without adversely affecting perioperative morbidity or long-term survival. 相似文献4.

Background
Minimally invasive distal pancreatectomy (MISDP) has been shown to be safe relative to open distal pancreatectomy (ODP). However, MISDP has been slow to adopt for pancreatic adenocarcinoma (PDAC). This study sought to compare outcomes following MISDP vs. ODP for PDAC.Methods
Data were prospectively collected from 2011 to 2014 for DP by the American College of Surgeons-National Surgical Quality Improvement Program. Patients without PDAC on surgical pathology were excluded. Impact of minimally invasive approach on morbidity and mortality was analyzed using two-way statistical analyses.Results
Of 6198 patients undergoing DP, 501 (7.5%) had a pathologic diagnosis of PDAC. MISDP was undertaken in 166 (33.1%) patients, ODP was performed in 335 (66.9%). MISDP and ODP were not different in preoperative comorbidities or pathologic stage. Overall morbidity (MISDP 31%, ODP 42%; p = 0.024), transfusion (MISDP 6%, ODP 23%; p = 0.0001), pneumonia (MISDP 1%, ODP 7%; p = 0.004), surgical site infections (MISDP 8%, OPD 17%; p = 0.013), sepsis (MISDP 2%, ODP 8%; p = 0.007), and length of stay (MISDP 5.0 days, ODP 7.0 days; p = 0.009) were lower in the MIS group. Mortality (MISDP 0%, ODP 1%; p = 0.307), pancreatic fistula (MISDP 12%, ODP 19%; p = 0.073), and delayed gastric emptying (MISDP 3%, ODP 7%; p = 0.140) were similar.Conclusions
This analysis of a large multi-institution North American experience of DP for treatment of pancreatic adenocarcinoma suggests that short-term postoperative outcomes are improved with MISDP. 相似文献5.

Background
Gallbladder cancer (GBC) is the most common biliary tract malignancy. Because it commonly metastasizes via lymphatics, portal lymphadenectomy should be included in oncologic resections. This study aimed to compare the oncologic equivalence of the laparoscopic versus open technique by evaluating lymph node (LN) yield.Methods
The 2010–2012 National Cancer Data Base identified patients who underwent laparoscopic or open resection of GBC with dedicated lymphadenectomy. LN yield was compared by resection method. Variables associated with LN yield ≥3 were identified.Results
Of 1524 patients identified, 52% were intended to undergo laparoscopic surgery, with 20% of these patients converted to open. Collection of ≥3 LNs following open resection (47%) was higher than for laparoscopic resection (34%), p < 0.001. Operations performed at high-volume (aOR:1.74, p < 0.001) and/or academic centers (aOR:1.70, p = 0.024) had superior LN yield. LN yield was not associated with overall survival (aHR:0.93, p = 0.493).Conclusions
In this analysis of national data, LN yield following laparoscopic resection for GBC was significantly lower than following open resection. Open resection is more frequently performed at academic centers, possibly to assure adequate oncologic resection. Enforcing consensus guidelines for lymphadenectomy in gallbladder cancer will optimize outcomes as minimally invasive approaches evolve. 相似文献6.

Background
Exosomes are nanovesicles that have been shown to mediate carcinogenesis in pancreatic ductal adenocarcinoma (PDAC). Given the direct communication of pancreatic duct fluid with the tumor and its relative accessibility, we aimed to determine the feasibility of isolating and characterizing exosomes from pancreatic duct fluid.Methods
Pancreatic duct fluid was collected from 26 patients with PDAC (n = 13), intraductal papillary mucinous neoplasm (IPMN) (n = 8) and other benign pancreatic diseases (n = 5) at resection. Exosomes were isolated by serial ultracentrifugation, proteins were identified by mass spectrometry, and their expression was evaluated by immunohistochemistry.Results
Exosomes were isolated from all specimens with a mean concentration of 5.9 ± 1 × 108 particles/mL and most frequent size of 138 ± 9 nm. Among the top 35 proteins that were significantly associated with PDAC, multiple carcinoembryonic antigen-related cell adhesion molecules (CEACAMs) and extracellular matrix (ECM) proteins were identified. Interestingly, CEACAM 1/5 expression by immunohistochemistry was seen only on tumor epithelia whereas tenascin C positivity was restricted to stroma, suggesting that both tumor and stromal cells contributed to exosomes.Conclusion
This is the first study showing that exosome isolation is feasible from pancreatic duct fluid, and that exosomal proteins may be utilized to diagnose patients with PDAC. 相似文献7.

Background
Laparoscopic liver resection for hepatocellular carcinoma is well described in early cirrhosis. Less is known regarding outcomes with more advanced cirrhosis, and this study aimed to compare these groups.Methods
A retrospective review of resections at a high-volume hepatobiliary center over a 15-year period was performed. Primary end-points were 30 and 90-day mortality. Secondary end-points included complications and survival.Results
80 early (Child's A) were compared to 26 advanced (20 Child's B and 6 Child's C) patients. Baseline patient and tumor characteristics were similar except for parameters indicating degree of cirrhosis. Only early cirrhotic patients underwent anatomic hepatectomies (six cases) and median operative times were longer (151 vs 99 min, p = 0.03). Intraoperative blood loss, conversion, R0 resection, length-of-stay and perioperative complications were comparable. 30 and 90-day mortality were statistically similar (2.5 vs 0%, OR 1.69, 95% CI 0.08–36.19 and 2.5 vs 7.7%, OR 0.31 95% CI 0.04–2.30). There was a trend toward longer survival in the early cirrhotic group but this did not reach significance (50 vs 21 months, p = 0.077).Conclusions
In carefully selected advanced cirrhotic patients, laparoscopic liver resection may be performed with acceptable outcomes. Though this is not yet well established, further trials may be warranted. 相似文献8.

Background
Preoperative skeletal muscle depletion or sarcopenia has been suggested to predict worse outcome after resection of colorectal liver metastases. The aim of the present study was to investigate the impact of neoadjuvant chemotherapy on preoperative skeletal muscle mass prior to liver resection.Methods
Patients operated with liver resection for colorectal liver metastases between 2010 and 2014 were retrospectively reviewed. Muscle mass was evaluated by measuring muscle area on a cross-sectional computed tomography image at the level of the third lumbar vertebra, and normalized for patient height, presenting a skeletal muscle index.Results
Preoperative skeletal muscle mass was analysed in 225 patients, of whom 97 underwent neoadjuvant chemotherapy. In total 147 patients (65%) were categorized as sarcopenic preoperatively. Patients receiving neoadjuvant chemotherapy decreased in skeletal muscle mass (decrease by 5.5 (?1.1 to 11) % in skeletal muscle index, p < 0.001). Patients with muscle loss >5% during neoadjuvant chemotherapy were less likely to undergo adjuvant chemotherapy than others (68% vs 85%, p = 0.048). A >5% muscle loss did not result in worse overall (p = 0.131) or recurrence-free survival (p = 0.105).Conclusion
Skeletal muscle mass decreases during neoadjuvant chemotherapy. Skeletal muscle loss during neoadjuvant chemotherapy impairs the conditions for adjuvant chemotherapy. 相似文献9.

Background
Hilar malignancy can occasionally be associated with high grade dysplasia (HGD) adjacent to invasive malignancy. For patients with HGD extending into the intrapancreatic bile duct, the authors adopted intrapancreatic bile duct resection (IP-BDR). The aims of this study were to compare the incidence of clinically relevant postoperative pancreatic fistula (CR-POPF), distal R0 resection and local recurrence within the distal bile duct remnant for patients undergoing extrahepatic bile duct resection without pancreaticoduodenectomy (with or without IP-BDR).Methods
Patients who presented with hilar malignancy and underwent extrahepatic bile duct resection without pancreaticoduodenectomy between January 2005 and December 2016 were identified and the outcomes retrospectively evaluated.Results
Of 217 patients who met the inclusion criteria 62 (29%) patients underwent IP-BDR. There was a significant difference between patients undergoing standard resection vs. IP-BDR in terms of CR-POPF (5% (8/155) patients: vs 18% (11/62), p < 0.001). There were no significant differences between two groups of R0 status on distal margin (5% (8/155) patients: vs 10% (6/62), p = 0.359). No patient developed recurrence within the residual intrapancreatic bile duct.Discussion
The incidence of CR-POPF after IP-BDR for hilar malignancies was 18%. IP-BDR was associated with CR-POF, but does not appear to alter survival or local recurrence rate. 相似文献10.

Background
High-volume centers have to deal with long surgical waiting-lists leading to a potential delay in treatment. This study assessed whether a longer time from diagnosis to surgery worsened pathological and survival outcomes in resectable pancreatic ductal adenocarcinoma (PDAC).Methods
A retrospective analysis of patients treated for resectable PDAC. Difference in size between preoperative CT-scan and specimen, pathological features, the rate of vascular and R1 resections as well as recurrence and survival were analyzed depending on the waiting time using a 30-day cut-off.Results
Waiting more than 30 days for surgery was associated with an increase in tumor size on specimen when compared with CT-scan (+3 vs. +1 mm, p = 0.04). T and N status, rate of vascular resection, grading, perineural and lymphovascular infiltration, and R1 rates did not differ between groups, as well as tumor recurrence (48.8% vs. 48.9%, p = 0.5) and survival (31 vs. 29 months, p = 0.7). For PDAC < 20 mm, waiting less than 30 days improved overall survival (p = 0.02).Conclusion
The duration of the surgical waiting-list did not affect pathological features and survival. Delayed surgery was associated with increased cancer size on the specimen. However, surgery should not be delayed for PDACs < 20 mm as this may negatively affect the prognosis. 相似文献12.

To report long-term follow up of a phase II, single-arm trial of resectable pancreatic ductal adenocarcinoma (PDAC) treated with adjuvant interferon-based chemoradiation followed by gemcitabine to determine survival, recurrence, and complications.
Methods
From 2002 to 2005, 53 patients with PDAC underwent pancreaticoduodenectomy and received adjuvant interferon-based chemoradiation consisting of external-beam irradiation and simultaneous 3-drug chemotherapy of continuous daily 5-fluorouracil infusion, weekly intravenous bolus cisplatin, and subcutaneous interferon-α, followed by two months of weekly intravenous gemcitabine.Results
Actual overall survival for the 5- and 10-year periods were 26% and 10%, respectively, with a median overall survival of 25 months (95% CI: 16.4–38.5). Adverse prognostic factors on multivariate analysis were positive tumor margin (p < 0.035), lymphovascular invasion (p < 0.015), and perineural invasion (p < 0.026). Median time to recurrence was 11 months. Positive tumor margin was associated with lymph node involvement (p < 0.005), portal vein resection (p < 0.038), and metastases (p < 0.018). Late complications were frequent and predominated by gastrointestinal and infectious complications.Conclusions
Adjuvant interferon-based chemoradiation for PDAC improves long-term survival compared to standard therapy. However, recurrence rates and long-term complications remain high, thus further studies are indicated to assess patient characteristics that indicate a favorable treatment profile. 相似文献13.

Aims
The aim of this study was to determine whether a combination of the tumour markers carcinoembryonic (CEA) and carbohydrate antigen 19-9 (CA19-9) would be helpful in predicting the prognosis of patients with gallbladder carcinoma (GBC) who underwent resection.Methods
A retrospective analysis of clinico-pathological features and survival of 390 patients with GBC who were treated between January 2003 and December 2013. Time-dependent receiver operating characteristic (ROC) was used to evaluate the prognostic ability of tumour markers. Combinations of preoperative CEA and CA19-9 were tested as potential prognostic factors.Results
The evaluation of preoperative CEA and CA19-9 showed that patients with both tumour markers within the normal range had the best prognosis with a median survival of 27 months and R0 rate of 86%. Patients with both tumour markers elevated had the poorest prognosis and lower R0 rate (p < 0.001). The combination of CEA and CA19-9 was an independent risk factor for overall survival. The AUROC at 5 years of combination of CEA and CA19-9 was 0.798, which was similar to CEA (0.765) or CA19-9 (0.771) alone (p = 0.103, p = 0.147).Conclusions
A combination of an elevated preoperative CEA and CA19-9 was associated with a worse prognosis for patients with GBC who underwent resection. 相似文献14.

Background
Western guidelines recommend resection for hepatocellular carcinoma (HCC) in so-called ideal cirrhotic patients with a Barcelona Clinic Liver Cancer (BCLC) stage 0-A tumour. This study compares short-term outcomes following resection between patients defined as ideal and nonideal according to the BCLC guidelines.Methods
This prospective single-centre open study (ClinicalTrials.govNCT02145013) included all cirrhotic patients with HCC referred for resection from 2014 to 2016. Mortality, morbidity, unresolved liver decompensation, and readmission were measured.Results
The study population included 65 consecutive patients: 32 (49%) ideal and 33 (51%) nonideal. Ideal and nonideal groups did not differ in mortality (3% vs. 6%; p = 0.57), morbidity (53% vs. 73%; p = 0.10), or unresolved liver decompensation (6% vs. 15%; p = 0.23) at 90 days. The readmission rate was higher in the nonideal (21%) than in the ideal group (3%; p = 0.02).Conclusion
Straying from the current guidelines for resection in a selected subset of nonideal patients doubled the number of resections performed for treating HCC, with satisfactory short-term outcomes. These results argue for the expansion of the acknowledged BCLC guidelines. 相似文献15.

Background
The aim of this study was to describe the outcome of patients with colorectal liver metastases (CRLM) and radiological or clinical evidence of metastatic hepatic lymph node involvement who underwent combined hepatectomy and hepatic pedicle lymphadenectomy.Methods
Retrospective analysis of a prospectively maintained audit of 2082 patients undergoing liver resection for CRLM between 1994 and 2014. Age, type of resection, CT/MRI/PET detection, location, disease recurrence and survival were analysed.Results
Combined hepatectomy and hepatic pedicle lymphadenopathy was performed on 76 patients who met the inclusion criteria. 46% of enlarged lymph nodes were located in the hepatic ligament, with 38% retroportal, 38% common hepatic and 33% coeliac nodes. 50% of lymph node resections were positive for metastatic tumour. Pre-operative CT, MRI and CT/PET failed to detect histologically proven lymph node disease in 25/38 patients. Patients with negative nodal histology had a significant overall (44 vs 20 months, p = 0.008) and disease free (20 vs 11 months, p < 0.001) survival advantage.Conclusion
Combined hepatectomy and lymph node resection for CRLM in the setting of enlarged or suspicious lymphadenopathy is justified as imaging and operative findings are poor guides in determining positive lymph node disease. 相似文献16.

Background
Radical resection of advanced pancreatic cancer may occasionally require a simultaneous colon resection. The risks and benefits of this combined procedure are largely unknown. This systematic review aimed to assess short and long term outcome after pancreatoduodenectomy with colon resection (PD-colon) for pancreatic ductal adenocarcinoma (PDAC).Methods
A systematic literature search was performed in PubMed, Embase, and the Cochrane Library for studies published between 1994 and 2017 concerning PD-colon for PDAC.Results
After screening 2038 articles, 5 articles with a total of 181 patients undergoing PD-colon were eligible for inclusion. Included studies showed a relatively low risk of bias. The pooled complication rate was 73% (95% CI 61–84) including a pooled colonic anastomotic leak rate of 5.5%. Pooled mortality was 10% (95% CI 6–15). Pooled mean survival (data from 86 patients) was 18 months (95% CI 13–23) with pooled 3- and 5-year survival of 31% (95% CI 20–72) and 19% (95% CI 6–38).Conclusion
Based on the available data, PD-colon for PDAC seems to be associated with an increased morbidity and mortality but with survival comparable with standard PD in selected patients. Future large series are needed to allow for better patient selection for PD-colon. 相似文献17.

Objectives
We retrospectively investigated the operative outcomes of patients who underwent distal pancreatectomy (DP) for invasive pancreatic ductal adenocarcinoma (PDAC) located at the body and tail.Methods
Data from 395 patients with PDAC who underwent DP with margin-negative resection (R0 or R1) were collected from seven high-volume centers in Japan from 2001 to 2012. Among them, 72 patients underwent DP with en-bloc celiac axis resection (DP-CAR). The remaining 323 patients underwent conventional DP with splenectomy (DP-S). To determine the efficacy of DP-CAR, clinicopathological data were compared between the DP-CAR and the DP-S groups.Results
The DP-S group consisted mainly of patients with resectable disease (93%), and conversely, all patients in the DP-CAR group had borderline resectable or unresectable disease. The overall morbidity was significantly higher in the DP-CAR group than in the DP-S group (63% vs 47%, respectively; P = 0.017). The median survival time (MST) of the DP-CAR group was significantly shorter than that of the DP-S group (17.5 vs 28.6 months, respectively; P = 0.004). However, the MST of patients in the DP-CAR group (n = 61, 85%) who received adjuvant therapy was significantly longer than that of patients in the DP-S group (n = 65, 20%) who underwent R1 resection (21.9 vs 16.7 months, respectively; P = 0.024).Conclusion
DP-CAR followed by adjuvant chemotherapy provided an acceptable overall survival rate in patients with highly advanced PDAC, but should be performed with great caution because of high morbidity. Patients with a high risk of positive surgical margins with DP-S may be candidates for DP-CAR. 相似文献18.

Background
Whether primary tumor resection benefits patients with synchronous multifocal liver metastases from pancreatic neuroendocrine tumors remains controversial. We investigated whether primary tumor resection significantly affects survival in this study.Methods
A retrospective study of patients with synchronous multifocal liver metastases from pancreatic neuroendocrine tumors between 1998 and 2016 was performed. Patient demographics, operation details, adjuvant treatment, and pathological and survival information were collected, and relevant clinical-pathological parameters were assessed in univariate and multivariate survival analyses.Results
Sixty-three patients were included in this study, including 35 who underwent primary tumor resection. The median survival time and 5-year survival rate of this cohort were 50 months and 44.5%, respectively. Median survival time in the resected group was significantly longer at 72 months than that of 32 months in the nonresected group (p?=?0.010). Multivariate analysis showed that primary tumor surgery was a significant independent prognostic factor (HR 0.312, 95% CI: 0.128–0.762, p?=?0.011).Conclusions
Primary tumor resection significantly benefits patients with synchronous multifocal liver metastases from pancreatic neuroendocrine tumors. 相似文献19.

Introduction
Pancreatoduodenectomy (PD) typically follows preoperative biliary drainage (PBD) despite PBD being potentially harmful. This study evaluated a pathway to avoid PBD within the framework of the UK's NHS.Method
A prospective observational study of jaundiced patients undergoing PD for periampullary cancer. A pathway to provide early surgery without PBD was introduced at the start of the study period.Results
Over 12 months 61 and 32 patients underwent surgery with and without PBD respectively; 95% of patients in the PBD group had been stented before referral. The time from CT scan to surgery was shorter in the no PBD group (16 vs 65 days, p < 0.0001). Significantly more patients underwent PD in the no PBD group (31/32 vs 46/61, p = 0.009) and venous resection (10/31 vs 4/46, p = 0.014). The sensitivity of initial CT scan to define borderline resectable disease was worse in the PBD group (91 vs 50%, p = 0.042).Conclusions
Early surgery to avoid PBD is possible within the NHS. By reducing the time to surgery it appears that more patients undergo potentially curative resection. It is desirable to understand why surgery without PBD is not performed routinely as are the development of strategies to support its more widespread practice. 相似文献20.
