Background
Socioeconomic inequalities in colorectal cancer (CRC) survival are well recognised. The aim of this study was to describe the impact of socioeconomic deprivation on survival in patients with synchronous CRC liver-limited metastases, and to investigate if any survival inequalities are explained by differences in liver resection rates.Methods
Patients in the National Bowel Cancer Audit diagnosed with CRC between 2010 and 2016 in the English National Health Service were included. Linked Hospital Episode Statistics data were used to identify the presence of liver metastases and whether a liver resection had been performed. Multivariable random-effects logistic regression was used to estimate the odds ratio (OR) of liver resection by Index of Multiple Deprivation (IMD) quintile. Cox-proportional hazards model was used to compare 3-year survival.Results
13,656 patients were included, of whom 2213 (16.2%) underwent liver resection. Patients in the least deprived IMD quintile were more likely to undergo liver resection than those in the most deprived quintile (adjusted OR 1.42, 95% confidence interval (CI) 1.18–1.70). Patients in the least deprived quintile had better 3-year survival (least deprived vs. most deprived quintile, 22.3% vs. 17.4%; adjusted hazard ratio (HR) 1.20, 1.11–1.30). Adjusting for liver resection attenuated, but did not remove, this effect. There was no difference in survival between IMD quintile when restricted to patients who underwent liver resection (adjusted HR 0.97, 0.76–1.23).Conclusions
Deprived CRC patients with synchronous liver-limited metastases have worse survival than more affluent patients. Lower rates of liver resection in more deprived patients is a contributory factor. 相似文献2.

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3.

Background
Squamous cell carcinoma (SCC) liver metastases still remains a difficult challenge and the effectiveness of resection for SCC liver metastases is unclear. The aim of this study was to analyze long-term outcomes of surgically treated patients with SCC liver metastases.Methods
The clinicopathological characteristics, overall survival (OS), and recurrence free survival (RFS) of all patients with SCC liver metastases resected between 1998 and 2015, were analyzed.Results
Among 28 patients who met inclusion criteria, there were 19 patients with anal cancer metastases (68%), 2 (7%) with cervix cancer metastases, 2 (7%) with tonsil cancer metastases, 2 (7%) with lung cancer metastases, 2 (7%) with primary unknown cancer metastases and 1 (4%) with vulvar cancer metastases. Four (14%) patients underwent major hepatectomy. There were no liver insufficiency cases or 90-day mortality. Cumulative 3- and 5-year OS rates were 52% and 47%. Cumulative 1- and 3-year RFS rates were 50% and 25%.Conclusions
Long-term outcomes after resection of SCC liver metastases compare favorably with those of colorectal or neuroendocrine liver metastases. Liver resection can be an effective treatment option for SCC liver metastases in appropriately selected patients after systemic therapy. 相似文献4.

Background and objectives
This study evaluates predictive factors for observed long-term survival of more than 5 and 10 years for patients after liver resection for hepatocellular carcinoma and compares their life expectancy to the normal national population matched for sex, year of birth and age at resection.Methods
230 patients after primary liver resection for HCC (01.01.1995–31.12.2004) were analyzed. Multivariable logistic regression models were determined based on Cox regression results and their prognostic capability evaluated with areas under the receiver operating characteristic curve (AUROCs).Results
Life years after surgery in deceased patients compared to the normal national population matched for sex, year of birth and age at resection was reduced by median 21.7 years. Independent predictive factors for 10-year survival were age at resection (p < 0.001; OR = 0.898; 95%-CI: 0.846–0.954), UICC 7 tumor staging (p = 0.003; OR = 0.344; 95%-CI: 0.126–0.941) and ASAT (GOT) in U/l divided by Quick in percent multiplied by the extent of liver resection graded in points labelled as the resection severity index (p < 0.001; OR = 0.136; 95%-CI: 0.022–0.843) enabling prediction of 10-year survival with an AUROC of 0.884. The same factors plus revision surgery (yes/no) predict 5-year survival (AUROC 0.736).Conclusions
Liver resection enables predictable long-term survival >5 and > 10 years. The proposed resection severity index quantifies the prognostic relevance of liver cellular damage, synthesis and loss of parenchyma for long-term survival. 相似文献5.

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6.

Background
Curative surgery of synchronous peritoneal metastases (PM) and colorectal liver metastases (LM) has been recently investigated as feasible option. When synchronous peritoneal and liver resection is not achievable, the sequence of the surgery remains unknown. Our hypothesis was that liver resection (LR) promotes peritoneal growth resulting in a non-resectable PM. We sought to analyse the effects of major LR and liver regeneration after hepatectomy in a murine model of PM and the associated angiogenesis.Methods
Murine model of colorectal PM in Balb/C mice was developed by intraperitoneal injection of different CT-26 tumour cell concentrations. Five days after the injection, mice were randomized into three groups: 68% hepatectomy group, sham laparotomy and control group without surgery. On post-operative days 1, 5 and 20, PM was evaluated macroscopically, tumour growth and liver regeneration by immunohistochemistry, and angiogenesis by immunofluorescence. Circulating progenitor cells, plasmatic cytokines and digestive arterial blood flow velocity measurements were also analysed.Results
Reproducible murine model of limited colorectal PM was obtained. Surgery induced PM increases and promoted neo-angiogenesis. Major hepatectomy influence the tumour growth in the late phase after surgery, the extent of extra-peritoneal metastasis and the increase of Ki-67 expression in the remnant liver.Conclusions
This animal model confirms the pro-tumoural and pro-angiogenic role of surgery, laparotomy and major LR, which promotes the increase of angiogenic factors and their participation in PM growth. These results suggest that peritoneal resection should be first step in the case of two-step liver and peritoneal surgery for patients with colorectal PM and LM. 相似文献7.

Background
The role of primary tumour surgery in pancreatic neuroendocrine tumours (PNETs) with unresectable liver metastases is controversial and international guidelines do not recommend surgery in such cases. Resectability of the primary tumour has never been considered in outcome comparisons between operated and non-operated patients.Methods
From two institutional prospective databases of patients affected by PNET and unresectable liver metastases, 63 patients who underwent a left-pancreatectomy at diagnosis were identified and compared with a group of 30 patients with a potentially resectable but not-resected primary tumour located in the body or tail. The endpoint was overall survival (OS).Results
The two groups significantly differed at baseline with regard to liver tumour burden Ki-67 labelling index, site of pancreas, results of the 18FDG PET-CT and age. In the operated patients, surgical morbidity comprised 7 cases of pancreatic fistula. Postoperative mortality was nil. Median OS for patients undergoing left-pancreatectomy was 111 months vs 52 for the non operated patients (p = 0.003). At multivariate analysis after propensity score adjustment, no surgery as well as liver tumour burden>25% and higher Ki-67 index were associated with an increased risk of death during follow-up. In patients with unresectable primary tumour, OS was similar in comparison to that in the resectable but non-resected patients, and significantly worse than that in the resected patients (p = 0.032).Conclusion
In PNETs located in the body or tail and diffuse liver metastases distal pancreatectomy may be justified in selected patients. Randomized studies may be safely proposed in future on this topic. 相似文献8.

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9.

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10.
Background
While the indications for surgery among patients with colorectal cancer liver metastases (CRCLM) are expanding, the role of surgery in patients with hepatic lymph node involvement remains controversial. We report management and outcomes in a population-based cohort of patients undergoing hepatectomy with concomitant hepatic lymphadenectomy for CRCLM.Methods
All cases of hepatectomy for CRCLM in the Canadian Province of Ontario from 2002 to 2009 were identified using the population-based Ontario Cancer Registry and linked electronic records of treatment. Pathology reports were used to identify concomitant lymphadenectomy with liver resection as well as extent of disease and surgical procedure.Results
Among 1310 patients who underwent resection for CRCLM, 103 (8%) underwent simultaneous regional lymphadenectomy. Seventy-one percent of cases with lymphadenectomy (70/103) had a major liver resection (≥3 segments). Of the 103 lymphadenectomy cases, 80 (78%) were hepatic pedicle, 16 (16%) were celiac and 7 (7%) were para-aortic. The mean number of nodes removed was 2.2 (range 1–15). Ninety-day mortality was 6%. Twenty-nine percent (30/103) of cases had positive nodes. Unadjusted overall survival at 5 years for positive vs negative nodes was 21% vs 42% (p = 0.003); cancer-specific survival was 10% vs 43% (p < 0.001). In adjusted analyses, hepatic node involvement was associated with inferior OS (HR 2.19, p = 0.010) and CSS (HR 3.07, p = 0.002).Conclusions
Patients with resected CRC liver metastases with regional lymph node involvement have inferior survival compared to patients with negative nodes. Despite this poor prognostic factor, a small proportion of cases with involved nodes will achieve long-term survival. 相似文献11.

Background
Resection quality after robot-assisted surgery for colorectal cancer have not previously been investigated in a nationwide study. The aim of the study was to examine the resection quality in robot-assisted versus laparoscopic surgery for colorectal cancer. Furthermore, 30-day mortality, postoperative complications, and conversion to open surgery were investigated.Methods
Patients undergoing either laparoscopic or robot-assisted surgery for colorectal cancer between 1 January 2010 and 31 December 2015 were included. The primary outcome was whether R0 resection was achieved. Secondary outcomes were 30-day mortality, postoperative complications, and conversions to laparotomy.Results
A total of 8615 and 3934 patients had a diagnosis of colon cancer and rectal cancer respectively. Of the patients with colon cancer, 511 patients underwent robot-assisted surgery and of the patients with rectal cancer, 706 patients underwent robot-assisted surgery.In the multivariate analysis, patients with colon cancer had an odds ratio (OR)?=?0.63 (95%CI 0.45–0.88) for receiving R0 resection in the robot-assisted group compared to laparoscopy. For patients with rectal cancer, the OR was 1.20 (95%CI 0.89–1.61). No difference in 30-day mortality or postoperative complications were observed. The OR of conversion to laparotomy was lower in the robot-assisted group compared to the laparoscopic group in both patients with colon – and rectal cancer.Conclusions
The study showed significant lower odds of receiving R0 resection in patients with colon cancer undergoing robot-assisted surgery. In patients with rectal cancer the robot-assisted surgery non-significantly increased the odds of receiving R0 resection. 相似文献12.

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13.

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14.

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15.

Background
Hepatic vascular inflow occlusion (VIO) can be applied during resection of colorectal liver metastases (CRLM) to control intra-operative blood loss, but has been linked to accelerated growth of micrometastases in experimental models. This study aimed to investigate the effects of hepatic VIO on disease-free and overall survival (DFS and OS) in patients following resection for CRLM.Methods
All patients who underwent liver resection for CRLM between January 2006 and September 2015 at our center were analyzed. Hepatic VIO was performed if deemed indicated by the operating surgeon and severe ischemia was defined as ≥20 min continuous or ≥45 min cumulative intermittent VIO. Cox regression analysis was performed to identify predictive factors for DFS and OS.Results
A total of 208 patients underwent liver resection for CRLM. VIO was performed in 64 procedures (31%), and fulfilled the definition of severe ischemia in 40 patients. Patients with severe ischemia had inferior DFS (5-year DFS 32% vs. 11%, P < 0.01), and inferior OS (5-year OS 37% vs. 64%, P < 0.01). At multivariate analysis, a high clinical risk score (Hazard ratio (HR) 1.60 (1.08–2.36)) and severe ischemia (HR 1.89 (1.21–2.97)) were independent predictors of worse DFS. Severe ischemia was not an independent predictor of OS.Conclusion
The present cohort study suggests that prolonged hepatic VIO during liver resection for CRLM was associated with reduced DFS. A patient-tailored approach seems advisable although larger studies should confirm these findings. 相似文献16.

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17.

Objectives
To assess the impact of a history of liver metastases on survival in patients undergoing surgery for lung metastases from colorectal carcinoma.Methods
We reviewed recent studies identified by searching MEDLINE and EMBASE using the Ovid interface, with the following search terms: lung metastasectomy, pulmonary metastasectomy, lung metastases and lung metastasis, supplemented by manual searching. Inclusion criteria were that the research concerned patients with lung metastases from colorectal cancer undergoing surgery with curative intent, and had been published between 2007 and 2014. Exclusion criteria were that the paper was a review, concerned surgical techniques themselves (without follow-up), and included patients treated non-surgically. Using Stata 14, we performed aggregate data and individual data meta-analysis using random-effect and Cox multilevel models respectively.Results
We collected data on 3501 patients from 17 studies. The overall median survival was 43 months. In aggregate data meta-analysis, the hazard ratio for patients with previous liver metastases was 1.19 (95% CI 0.90–1.47), with low heterogeneity (I2 4.3%). In individual data meta-analysis, the hazard ratio for these patients was 1.37 (95% CI 1.14–1.64; p < 0.001). Multivariate analysis identified the following factors significantly affecting survival: tumour-infiltrated pulmonary lymph nodes (p < 0.001), type of resection (p = 0.005), margins (p < 0.001), carcinoembryonic antigen levels (p < 0.001), and number and size of lung metastases (both p < 0.001).Conclusions
A history of liver metastases is a negative prognostic factor for survival in patients with lung metastases from colorectal cancer. We registered the meta-analysis protocol in PROSPERO (CRD42015017838). 相似文献18.

Background
Recent studies have demonstrated an association between beta-blocker exposure and improved survival in multiple cancer types. We sought to investigate the effects of beta-blockers at the time of index surgery for breast, lung, and colorectal cancer.Materials and methods
Using linked data from a provincial cancer registry, we conducted a retrospective matched cohort study comparing disease-specific and overall survival between patients over age 64 exposed and not exposed to beta-blockers before and after index surgical resection for breast, lung and colorectal cancer between April 1st, 2002 and December 31st, 2010. A high-dimensional propensity score was used to match patients and Cox proportional hazard models were used to estimate relative risks of the outcomes.Results
30,020 patients were included in the final matched cohorts. Mean follow up time for breast, lung, and colorectal cancer was 57.6 ± 30.5, 43.1 ± 28.7, and 53.4 ± 31.0 months, respectively. The adjusted hazard ratio for disease-specific mortality for patients exposed to beta-blockers was 1.03 (0.83–1.29) for breast, 1.05 (0.92–1.20) for lung, and 1.10 (0.96–1.25) for the colorectal cancer cohort.Conclusions
In this large population-based study, no association between perioperative beta-blocker exposure and improved cancer-specific survival for breast, lung, or colorectal cancer was demonstrated. 相似文献19.

Background
Surgical resection is an established therapeutic strategy for colorectal cancer (CRC) metastasis. However, controversies exist when CRC liver and lung metastases (CLLMs) are found concomitantly or when recurrence develops after either liver or lung resection. No predictive score model is available to risk stratify these patients in preparation for surgery, and cure has not yet been reported.Patients and Methods
All consecutive patients who had undergone surgery for CLLMs at our institution during a 20-year period were reviewed. Our policy was to propose sequential surgery of both sites with perioperative chemotherapy, if the strategy was potentially curative. Overall survival, disease-free survival, and cure were evaluated.Results
Sequential resection was performed in 150 patients with CLLMs. The median number of liver and lung metastases resected was 3 and 1, respectively. The median follow-up period was 59 months (range, 7-274 months). The median, 5-year, and 10-year overall survival was 76 months, 60%, and 35% respectively. CRC that was metastatic at the initial diagnosis (P = .012), a prelung resection carcinoembryonic antigen level > 100 ng/mL (P = .014), a prelung resection cancer antigen 19-9 level > 37 U/mL (P = .034), and an interval between liver and lung resection of < 24 months (P = .024) were independent poor prognostic factors for survival. The 5-year survival was significantly different for patients with ≤ 2 and ≥ 3 risk factors (77.3% vs. 26.5%). Of 75 patients with ≥ 5 years of follow-up data available from the first metastasis resection, 15 (20%) with disease-free survival ≥ 5 years were considered cured. The use of targeted therapy was the only independent predictor of cure.Conclusion
Curative-intent surgery provides good long-term survival and offers a chance of cure in select patients. Patients with ≤ 2 risk factors are good candidates for sequential resection. 相似文献20.
