Background
The oncological impact of surgical complications has been studied in visceral and pancreatic cancer.Aim
To investigate the impact of complications on tumour recurrence after resections for pancreatic neuroendocrine tumours.Methods
We have retrospectively analysed 105 consecutive resections performed at the Royal Free London Hospital from 1998 to 2014, and studied the long-term outcome of nil-minor (<3) versus major (≥3) Clavien–Dindo complications (CD) on disease-free (DFS) and overall survival (OS).Results
The series accounted for 41 (39%) pancreaticoduodenectomies, two (1.9%) central, 48 (45.7%) distal pancreatectomies, eight (7.6%) enucleations, four (3.8%) total pancreatectomies. Sixteen (15.2%) were extended to adjacent organs, 13 (12.3%) to minor liver resections. Postoperative complications presented in 43 (40.1%) patients; CD grade 1 or 2 in 23 (21.9%), grades ≥3 in 20 (19%). Among 25 (23.8%) pancreatic fistulas, 14 (13.3%) were grades B or C. Thirty-four (32.4%) patients developed exocrine, and 31 (29.5%) endocrine insufficiency. Seven patients died during a median 27 (0–175) months follow up. Thirty-day mortality was 0.9%. OS was 94.1% at 5 years. Thirty tumours recurred within 11.7 (0.8–141.5) months. DFS was 44% at 5 years. At univariate analysis, high-grade complications were not associated with shorter DFS (p = 0.744). At multivariate analysis, no parameter was independent predictor for DFS or OS. The comparison of nil-minor versus major complications showed no DFS difference (p = 0.253).Conclusion
From our series, major complications after P-NETs resection are not associated to different disease recurrence; hence do not require different follow up or adjuvant regimens. 相似文献2.

Background
Postoperative complications influence overall and disease free survival after pancreaticoduodenectomy for pancreatic ductal adenocarcinoma is still a matter of debate and controversy.Methods
The outcome of 942 consecutive patients, from the multicentric study of the French Association of Surgery, between January 2004 and December 2009 was analyzed. Perioperative data, including severe complications (grade III and above), were used in univariate and multivariate analysis to assess their influence on overall and disease free survival. Recurrence and its location were investigated as well.Results
Median overall and disease free survival were 24 and 19 months respectively. Postoperative complications occurred in 444 patients (47%) with 18.3% of severe complications. On multivariate analysis, severe complications, positive lymph node status and R1-R2 resection were independent prognostic factors for both overall and disease free survival. The median overall survival decreased from 25 to 22 months (p = 0.005) and disease free survival from 21 to 16 months (p = 0.02) if severe complications occurred. Severe complications were independent prognostic factor of recurrence (p < 0.001).Conclusions
Severe complications significantly alter both overall and disease free survival and are an independent factor of recurrence. 相似文献3.

Background
In metastatic disease (M1), chemotherapy (expected survival: 6–10 months) is considered the only treatment option. The aim of this study was to evaluate the outcome of curative M1 PDAC resections.Methods
Prospective data of all patients undergoing primary tumour and metastasis resection for stage IV PDAC during a 12-year period was analysed regarding localisation (liver or distant interaortocaval lymph nodes; ILN), morbidity and survival. Patients were stratified with regard to syn- or metachronous metastases resection.Results
Patients (n = 128) undergoing PDAC and metastases resection (intention-to-treat, oligometastatic stage; liver n = 85; ILN n = 43) were included. Surgical morbidity and 30-day mortality after synchronous resection of M1 tumours were 45% and 2.9%, respectively. Overall median survival after M1 resection was 12.3 months in both groups. Long-term outcome showed a 5-year survival of 8.1% after surgery for both liver metastases and 10.1% following ILN resection.Conclusions
The present collective is the largest series of resected metastatic PDAC and shows that resection of liver or ILN metastases can be done safely and should be considered as it may be superior to palliative treatment, and it is associated with long-term survival of 10% in selected patients. Further studies to stratify patients for these procedures are warranted. 相似文献4.

Background
Identification of factors associated with dismal survival after surgery in resectable pancreatic ductal adenocarcinoma is important to select patients for neoadjuvant treatment. The present meta-analysis aimed to compare the results of distal pancreatectomy for resectable adenocarcinoma of the pancreatic body-tail with and without splenic vessels infiltration.Methods
A systematic search was performed of PubMed, Embase and the Cochrane Library in accordance with PRISMA guidelines. The inclusion criteria were studies including patients who underwent distal pancreatectomy for pancreatic cancer with or without splenic vessels infiltration. 5-year overall survival (OS) was the primary outcomes. Meta-analysis was carried out applying time-to-event method.Results
Six articles with 423 patients were analysed. Patients with pathological splenic artery invasion had a worse survival compared with those without infiltration (Hazard ratio 1.76, 95% CI 1.36–2.28; P < 0.0001). A similar results was found when considering pathological splenic vessels infiltration, showing that survival was significantly poorer when splenic vein infiltration was present (Hazard ratio 1.51, 95% CI 1.19–1.93; P = 0.0009).Conclusions
This meta-analysis showed worse survival for patients with splenic vessels infiltration undergoing distal pancreatectomy for pancreatic cancer. Splenic vessels infiltration represents the stigmata of a more aggressive disease, although resectable. 相似文献5.

Background
In locally advanced rectal cancer (LARC), beyond total mesorectal excision (bTME) is often necessary to obtain complete resection (R0). The aim of this study was to identify prognostic determinants and compare morbidity and survival in LARC cases requiring bTME or TME surgery.Method
Single centre cohort study of LARC cases where all patients received neoadjuvant radiotherapy (n = 332). Data was registered prospectively in an institutional database linked to the National Registry.Results
bTME surgery was performed in 224 patients, 171 with resections of adjacent organs (bTME-o group) and 53 with pelvic side-wall resections (bTME-pw group). TME surgery was performed in 108 patients. Six deaths occurred within 100 days and severe morbidity was registered in 23.8% of the whole cohort and in 25.4% of the bTME groups. The R0 rates were 93.5%, 84.2%, and 75.5% in the TME, bTME-o, and bTME-pw groups, respectively. Five-year disease free survival (DFS) was 67.3% (TME group), 54.5% (bTME-o group) and 48.7% (bTME-pw group), and five-year overall survival (OS) 78.7%, 69.0% and 60.4% respectively. Patients with involved resection margins (R1), high pT-stage, pN-positivity or poor response to neoadjuvant therapy were associated with inferior DFS and OS.Conclusion
In organ-threatening or infiltrating LARC, bTME surgery can be performed with low mortality and acceptable morbidity to obtain a good long-term outcome. Patients with pelvic side-wall infiltration were identified as a subgroup with increased risk of R1 resection and inferior long-term outcome. 相似文献6.

Objective
To assess clinical and pathologic efficacy of neoadjuvant FOLFIRINOX for locally advanced (LAPC) and borderline resectable pancreatic cancer (BRPC).Methods
Patients receiving neoadjuvant FOLFIRINOX for LAPC and BRPC treated between 2014 and 2017 were identified. Post-treatment patients achieving resectability were referred for surgery, whereas unresectable patients continued chemotherapy. Clinical and pathological data were retrospectively compared with control group consisting of 47 consecutive patients with BRPC undergoing pancreatic and portal vein resection between 2008 and 2017.Results
Thirty LAPC and 23 BRPC patients were identified. Reasons for unresectability included disease progression (70%), locally unresectable disease (18%), and poor performance status (11%). Three patients (10%) with LAPC, and 20 (87%) with BRPC underwent curative surgery. Compared with control group, perioperative complication rate (4.3% versus 28.9%, p = 0.016), and pancreatic fistula rate (0 versus 14.8%, p = 0.08) were lower. Peripancreatic fat invasion (52.2% vs 97.8%, p = 0.001), lymph node involvement (22% vs 54.3%, p = 0.01), and surgical margin involvement (0 vs 17.4%, p = 0.04) were higher in the control group. Median survival was 34.3 months in BRPC patients operated after FOLFIRINOX and 26.1 months in the control group (p = 0.07). Three patients (13%) with complete pathological response are disease-free after mean follow-up of 19 months.Conclusions
Whereas neoadjuvant FOLFIRINOX rarely achieves resectability in patients with LAPC (10%), most BRPC undergo resection (87%). Neoadjuvant FOLFIRINOX leads to complete pathological response in 13% of cases, tumor downstaging, and a trend towards improved survival compared with patients undergoing up-front surgery. 相似文献7.

Background
The ideal management for patients with intermediate and advanced stage hepatocellular carcinoma (HCC) is controversial. The main purpose of this systematic review is to examine the role of liver resection in patients with intermediate stage HCC (multinodular HCCs) and in advanced stage HCC [mainly patients with portal vein tumor thrombosis (PVTT)].Methods
A systematic search of the literature was performed in Pud Med and the Cochrane Library from 01.01.2000 to 30.06.2016.Results
Twenty-three articles with 2412 patients with multinodular HCCs were selected. Also, 29 studies with 3659 patients with HCCs with macrovascular invasion were selected. In patients with multinodular HCCs the median post-operative morbidity was 25% and the 90-day mortality was 2.7%. The median survival was 37 months and the 5-year survival 35%. The 5-year survival was much better for patients with a number of HCCs ≤3 vs. HCCs >3 (49% vs. 23%).In patients with macrovascular invasion, who underwent hepatic resection, the median post-operative morbidity was 33% and the in-hospital mortality 2.7%. The median survival was 15 months. The 3 and 5year survival was 33% and 20% respectively. Moreover a significant difference in survival was noted according to PVTT stage: 5- year survival for distal PVTT, PVTT of the main intrahepatic PV branch and PVTT extending to the main PV was 45%, 19% and 14.5% respectively.Conclusions
Liver resection in patients with multinodular HCCs and HCCs with PVTT offers satisfactory long-term survival and should be considered in selected patients. 相似文献8.

Background
To describe, in patients with resectable pancreatic ductal adenocarcinoma (PDAC), the laparotomy findings, treatments and outcomes before (period 1) and after 2010 (period 2).Methods
From 2000 to 2015, patients newly diagnosed with resectable PDAC at Paoli-Calmettes Institute, France, were evaluated. Survival was examined using the Kaplan-Meier method, and statistical comparisons were conducted using log rank tests.Results
Among 1175 patients diagnosed with pancreatic mass, 164 underwent laparotomy with an intention of pancreatic resection. Some of them did not undergo pancreatic resection due to peroperative discovery of advanced disease. For those who were finally resected (n?=?119), there were fewer pancreaticoduodenectomies (p?=?0.045), shorter operation times (p?<?0.01), lower mortality rates (p?=?0.02), more advanced-stage tumors (T3), more frequent perineural invasion and R1 resection in period 2. This group had a trend of better outcomes after 2010 (51 months vs. 36 months (p?=?0.065)).Conclusion
Improvement in surgical procedures and postoperative management led to prolonged survival of those who underwent surgery for resectable pancreatic cancer since 2010, despite a higher frequency of advanced tumors at the diagnosis in our institution. 相似文献9.

Background
Robotic low anterior resection (RLAR) and transanal total mesorectal excision (TaTME) are novel surgical techniques for resection of rectal cancer. To our knowledge, no data exist on direct comparison of these procedures in terms of oncological or functional parameters.Methods
60 RLAR and 55 TaTME for rectal cancer were compared in respect to patient characteristics, clinicopathological parameters, intraoperative and perioperative results and anatomopathological outcome.Results
62 surgeries addressed tumors of the lower third (53.9%). No intergroup differences in terms of patient characteristics and clinicopathological parameters were observed. Operating time did not differ between groups (p = 0.312), nor did the perioperative complication rate (p = 0.176). Circumferential resection margin was wider in the RLAR than in the TaTME group (p < 0.001), while no differences were found in the remaining oncological parameters.Conclusion
Our study shows comparable results for RLAR and TaTME in rectal cancer treatment. Both procedures should be considered equally feasible for low rectal cancer cases and as an alternative to conventional anterior resections (open or laparoscopic). Furthermore, both techniques allow excellent oncological outcome especially in patients with anatomical limitations. 相似文献10.

Background
We performed a meta-analysis of previous reports evaluating the effect of mFIO (modified FOLFIRINOX; leucovorin, 5-fluorouracil, irinotecan, oxaliplatin) regimens in advanced pancreatic cancer.Materials and Methods
We performed a meta-analysis of reported studies in PubMed, Scopus, and Web of Science (1950-2016) in December 2016. The inclusion criteria were randomized trials, prospective or retrospective cohorts, patients with metastatic pancreatic adenocarcinoma, the use of mFIO or FOLFIRINOX (FIO) chemotherapy, and available information for ≥ 1 efficacy endpoint (response rate, progression-free survival, and/or overall survival). The outcomes were compared according to the chemotherapy regimen using a random effects model. We also performed a meta-regression analysis to evaluate the effect of dose reductions on outcomes.Results
Of 2525 abstracts, 32 were considered eligible. Modifications in the FIO regimen included omission of the 5-fluorouracil bolus and/or dose reductions in infusional 5-fluorouracil, irinotecan, and/or oxaliplatin. mFIO was not associated with inferior response rates (32% vs. 33%; P = .879), lower rates of survival at 11 months (47% vs. 50%; P = .38), or lower 6-month progression-free survival rates (47% vs. 53%; P = .38). The meta-regression of the percentage of dose reduction failed to show any association.Conclusion
The results of the present meta-analysis with a combined sample size of 1461 patients suggest that it is reasonable to consider mFIO regimens for patients with metastatic pancreatic adenocarcinoma. 相似文献11.

Introduction
The benefit of portal-superior mesenteric vein resection (PSMVR) with pancreatoduodenectomy (PD) remains controversial. This study assesses the impact of PSMVR on resection margin status and survival.Method
An electronic search was performed to identify relevant articles. Pooled odds ratios were calculated for outcomes using the fixed or random-effects models for meta-analysis. A decision analytical model was developed for estimating cost effectiveness.Results
Sixteen studies with 4145 patients who underwent pancreatoduodenectomy were included: 1207 patients had PSMVR and 2938 patients had no PSMVR. The R1 resection rate and post-operative mortality was significantly higher in PSMVR group (OR1.59[1.35, 1.86] p=<0.0001, and OR1.72 [1.02,2.92] p = 0.04 respectively). The overall survival at 5-years was worse in the PSMVR group (HR0.20 [0.07,0.55] P = 0.020). Tumour size (p = 0.030) and perineural invasion (P = 0.009) were higher in the PSMVR group. Not performing PSMVR yielded cost savings of $1617 per additional month alive without reduction in overall outcome.Conclusion
On the basis of retrospective data this study shows that PD with PSMVR is associated with a higher R1 rate, lower 5-year survival and is not cost-effective. It appears that PD with PSMVR can only be justified if R0 resection can be achieved. The continuing challenge is accurate selection of these patients. 相似文献12.

Background
Radiofrequency (RF)-assisted liver resection allows non-anatomical liver resection with reduced blood loss and offers the opportunity for a combination of resection and ablation. However, there are still concerns with regard to postoperative complications related to this technique. In the present study, we discuss the technical aspects of RF-assisted liver resections and analyse the rate of perioperative complications, focusing on post-hepatectomy liver failure (PLF), bile leak and abscess, and mortality.Methods
Between 2001 and 2015, 857 consecutive open and laparoscopic elective RF-assisted liver resections for benign and malignant liver tumours were reviewed retrospectively to assess perioperative outcomes.Results
Median intraoperative blood loss was 130?mL, with 9.8% of patients requiring blood transfusion. Intra-abdominal collections requiring percutaneous drainage developed in 8.7% of all patients, while bile leak at resection margin developed in 2.8% of the cases. Major liver resection was performed in 34% of patients and the incidence of PLF was 1.5% with one directly related mortality (0.1%).Conclusion
RF-assisted liver resection has evolved into a feasible and safe technique of liver resection with an acceptable incidence of perioperative morbidity and a low incidence of PLF and related mortality. 相似文献13.

Background
Primary tumour location has long been debated as a prognostic factor in colorectal cancer patients with liver metastases (CRLM) undergoing liver resection. This retrospective study was conducted to clarify the prognostic value of tumour location after radical hepatectomy for CRLM and its underlying causes.Methods
We retrospectively analysed clinical data from 420 patients with CRLM whom underwent liver resection between January 2002 and December 2015. Right-sided (RS) tumours include tumours located in the cecum, ascending colon, and transverse colon, and left-sided (LS) tumours include those located in the splenic flexure, descending colon, sigmoid colon, and rectum.Results
Both overall survival (OS) and disease-free survival (DFS) were similar between patients with RS and LS primary tumours (5-year OS: 46.5% vs 38.3%, P = 0.699; 5-year DFS: 29.1% vs 22.4%, P = 0.536). Specifically, RAS mutation rate was significantly higher in patients with RS tumours (P = 0.007). Subgroup analysis showed that the RAS mutation on the LS and RS tumours have different prognostic impact for CRLM patients on long-term survival after hepatic resection (RS, OS: P = 0.437, DFS: P = 0.471; LS, OS: P < 0.001, DFS: P = 0.002). The multivariable analysis showed that RAS mutant is an independent factor influencing OS in patients with LS primary tumour only.Conclusions
The site of the primary tumour has no significant impact on the long-term survival in patients with CRLM undergoing radical surgery. However, prognostic value of RAS status differs depending on the site of the primary tumour. 相似文献14.

Background
The incidence of pancreatic ductal adenocarcinoma (PDAC) is rapidly increasing. Up to 30% of patients present with locally advanced disease and therefore are not candidates for surgery. Locally advanced pancreatic cancer (LAPC) is an emerging entity lacking in level III evidence-based recommendations for its treatment. Currently, systemic chemotherapy is the main treatment for LAPC. However, due to lack of response or disease progression, downsizing of the tumour, making it resectable is successful in only a small proportion of patients. Radiotherapy is often advocated to improve local disease control if there is stability following chemotherapy. Recently, Irreversible Electroporation (IRE), a novel non-thermal ablation technique, has been proposed for the treatment of LAPC.Aims and methods
This narrative review aims to explore the potential role and timing for the use of IRE in patients with LAPC.Results
To date, there is limited and inconsistent level I and II evidence available in the literature regarding the use of IRE for the treatment of PDAC.Discussion
Although some of the preliminary experience of the use of IRE in patients with LAPC is encouraging, it should only be used after conventional evidence-based treatments and/or within the research context. 相似文献15.

Background
Multi-visceral resection, including parts of the urinary tract, is sometimes warranted to achieve cancer clear resection margins and optimize survival in patients with locally advanced colorectal and anal cancer. The aim of this study was to assess morbidity after urinary tract reconstruction dictated by colorectal and anal malignancy and to identify potential predictors of urological complications.Methods
All patients undergoing surgery for colorectal or anal malignancy, including urinary tract resection and synchronous reconstruction, performed at the Karolinska University Hospital during 2004–2015 were included in this retrospective cohort study. Data was collected from medical records with follow-up until at least one year after the index surgery. Complications were graded according to the Clavien-Dindo classification system of surgical complications.Results
The study included 189 patients; 121 underwent cystectomy and 68 partial ureter resection. The rate of high grade urological complications was 22%. The risk of major urological complications was significantly higher in patients subjected to ureter resection compared to after cystectomy (OR 2.60, 95% CI 1.23–5.49). Also, preoperative radiotherapy and intestinal anastomotic dehiscence significantly increased the risk of high grade urological complications.Conclusion
To achieve potentially curative resections with uninvolved margins in patients with locally advanced colorectal and anal cancer, multi-visceral resection including urinary tract reconstruction can be performed with reasonable morbidity. 相似文献16.

Background
The aim of this population-based cohort study was to determine whether the addition of neoadjuvant chemoradiotherapy (nCRT) to surgery is associated with improved pathologic outcomes and survival in patients with cT2N0M0 esophageal cancer.Methods
Patients who underwent nCRT followed by surgery or surgery alone for cT2N0M0 esophageal cancer were identified from The Netherlands Cancer Registry database (2005–2014). Accuracy of clinical staging was assessed using the resection specimen as gold standard. After propensity score matching, influences of both treatment strategies on radical resection (R0) rates and overall survival were compared.Results
In total 533 patients were included; 353 underwent nCRT followed by surgery and 180 underwent surgery alone. In the nCRT group 32% of patients achieved a pathologic complete response. Clinical understaging was observed in 62% of the patients in the surgery alone group based on pT-stage (n = 30, 27%), pN-stage (n = 26, 23%), or both (n = 55, 50%). Propensity score matching resulted in 78 patients who underwent nCRT plus surgery versus 78 who underwent surgery alone. In the nCRT group radical resections were more frequently observed (99% vs. 89% p = 0.031) and resulted in improved 5-year overall survival (46% vs. 33%, p = 0.017).Conclusion
In this population-based study, clinical staging of cT2N0M0 esophageal cancer was highly inaccurate. Compared to surgery alone, neoadjuvant chemoradiotherapy was associated with higher radical resection rates and improved overall survival. 相似文献17.

Background
Increasingly, patients with multiple colorectal liver metastases (CLM) are surgically treated. Some studies have shown that patients with bilobar and unilobar multiple CLM have similar outcomes, but other have shown that patients with bilobar CLM have worse outcomes after resection. We aimed to compare clinical outcomes of surgical treatment of bilobar and unilobar CLM using propensity score matching.Methods
The single-institution study included patients who underwent hepatectomy for ≥3 histologically confirmed CLM during 1998–2014. Clinicopathologic characteristics and long-term outcomes were compared between patients with bilobar and unilobar CLM in a propensity-score-adjusted cohort.Results
A total of 473 patients met the inclusion criteria, 271 (57%) with bilobar and 202 (43%) with unilobar CLM. In the propensity-score-matched population (bilobar, 170; unilobar, 170), no differences were observed according to the distribution of CLM except for a greater frequency of concomitant ablation, and R1 resection in the bilobar group. There was no difference between the bilobar and unilobar groups in 5-year overall survival rates (46% and 49%, respectively; P = 0.740) or 3-year recurrence-free survival rates (21% and 24%, respectively; P = 0.674).Conclusions
Tumor distribution may not affect the curability of surgery for multiple CLM. Liver resection would be justified for selected patients with bilobar CLM. 相似文献18.

Background
The liver is the most common site of colorectal liver metastases (CRLM) and surgical resection improves overall survival in selected patients. Here, we investigate outcomes and relevant prognostic factors after repeated hepatic resections for CRLM.Methods
From a prospective database, 578 patients who underwent 788 resections of colorectal liver metastases were included into this study. In total, 169 patients underwent a second and 41 patients had a third operation due to intrahepatic metastatic recurrence. Univariate and multivariate analyses were performed to determine prognostic risk factors.Results
5-year overall survival was 36.7% (95% CI: 30.2%; 43.2%) and 10-year survival was 20.3% (95% CI: 7.6%; 33.0%) in patients undergoing single resection. In patients undergoing a second or third resection, 5- and 10-year survival rates were 56.6% (95% CI: 45.0%; 68.2%) and 21.9% (95% CI: 6.8%; 37.0%) or 53.2% (95% CI: 32.4%; 74.0%) and 25.4%, respectively. In patients undergoing single resection, established markers (number, size and pattern of CRLM [p = 0.030/0.015/<0.001], R-status [p = 0.001], surgical/medical complications [p = 0.001/0.008], CEA-level [p = 0.001] and Fong-Score [p = 0.02]) were significantly associated with survival. In patients undergoing three resections, the only predictive markers were pT-stage of the primary tumor in univariate analysis (p = 0.013) and metachronous metastasis and medical complications in multivariate analysis (p = 0.001/0.025). The Fong-Score had no predictive value in patients undergoing two (p = 0.08) or three (p = 0.7) resections.Conclusion
Established prognostic indicators are not applicable in patients undergoing repeated CRLM resection. In a highly-selected group of patients, repeated hepatic resections can be performed safely with favorable long-term outcomes. 相似文献19.

Background
The value of microscopic biliary and perineural invasion as prognostic biomarkers in patients with resectable colorectal liver metastases (CLM) who undergo neoadjuvant chemotherapy and liver resection is still unclear. This retrospective study was performed to elucidate this issue.Methods
Histologic slides of resected CLM of patients who underwent neoadjuvant bevacizumab-based chemotherapy and liver resection were investigated with respect to biliary and perineural invasion. Presence of invasion was correlated with radiologic and histologic response, recurrence-free survival (RFS) and overall survival (OS).Results
One hundred forty-one patients were enrolled. There was a significant association between biliary and perineural invasion, respectively (P = 0.001). Moreover, both biliary and perineural invasion were associated with bilobar metastatic spread and higher number of metastases, while perineural invasion was also associated with a higher Fong score. No significant association was found with response. In univariable analysis, biliary and perineural invasion were associated with shorter RFS (median 10.1 vs. 13.5 months, HR 2.09, P = 0.010 and 7.6 vs. 14.0, HR 2.23, P = 0.001, respectively). Biliary invasion was also associated with shorter OS (median 32.8 months vs. not reached, HR 2.78, P = 0.010), however these results did not remain significant in multivariable analysis.Conclusions
In patients with resectable colorectal liver metastases undergoing neoadjuvant bevacizumab-based chemotherapy and liver resection, biliary and perineural invasion are associated with higher tumor load but may not be prognostic biomarkers. 相似文献20.
