Abstract
BACKGROUND Colorectal cancer (CRC) patients with stage pT4b are a complex group as they show differences in tumor-infiltrated organs. Patients with the same stage often exhibit differences in prognosis after multivisceral resection (MVR). Thus far, some important prognostic factors have not been thoroughly investigated. Here, we identified the prognostic factors influencing CRC patients at the pT4bN0M0 stage to stratify the prognostic differences among patients. MATERIALS AND METHODS A retrospective analysis was conducted on patients diagnosed with locally advanced CRC and who underwent MVR at three medical institutions from January 2010 to December 2021. The prognostic factors affecting the survival of CRC patients at pT4bN0M0 stage were identified by multivariate Cox proportional hazard models. We then classified the prognosis into different grades on the basis of these independent prognostic factors. RESULTS We enrolled 690 patients with locally advanced CRC who underwent MVR; of these, 172 patients with pT4bN0M0 were finally included. Patients with digestive system [overall survival (OS): hazard ratio (HR)=0.441; 95% confidence interval (CI)=0.217-0.900; P =0.024; disease-free survival (DFS): HR=0.416; 95% CI=0.218-0.796; P =0.008) or genitourinary system invasion (OS: HR=0.405; 95% CI=0.193-0.851; P =0.017; DFS: HR=0.505; 95% CI=0.267-0.954; P =0.035) exhibited significantly better OS and DFS as compared to those with gynecological system invasion, while the OS and DFS were similar between the digestive system and genitourinary system invasion groups (OS: HR=0.941; 95% CI=0.434-2.042; P =0.878; DFS: HR=1.211; 95% CI=0.611-2.403; P =0.583). Multivariate analysis showed that age (OS: HR=2.121; 95% CI=1.157-3.886; P =0.015; DFS: HR=1.869; 95% CI=1.116-3.131; P =0.017) and type of organs invaded by CRC (OS: HR=3.107; 95% CI=1.121-8.609; P =0.029; DFS: HR=2.827; 95% CI=1.142-6.997; P =0.025) were the independent prognostic factors that influenced the OS and DFS of CRC patients with pT4bN0M0 disease. The OS and DFS of patients showing invasion of the gynecological system group were significantly worse ( P =0.004 and P =0.003, respectively) than those of patients with invasion of the nongynecological system group. On the basis of the above-mentioned two independent prognostic factors, patients were assigned to high-risk, medium-risk, and low-risk groups. Subgroup analysis showed that the OS and DFS of the medium-risk and high-risk groups were significantly worse ( P =0.001 and P =0.001, respectively) than those of the low-risk group. CONCLUSION Patients with pT4bN0M0 CRC show significant differences in their prognosis. The type of organs invaded by CRC is a valuable indicator for prognostic stratification of CRC patients with pT4bN0M0.

Abstract
INTRODUCTION The clinical role of lymphadenectomy (LAD) as part of hepatic resection for malignancies of the liver remains unclear. In this study, we aimed to report on the use cases and postoperative outcomes of liver resection and simultaneous LAD for hepatic malignancies (HM). MATERIALS AND METHODS Clinicopathological data from patients who underwent surgery at 13 German centers from 2017 to 2022 (n = 3456) was extracted from the StuDoQ|Liver registry of the German Society of General and Visceral Surgery. Propensity-score matching (PSM) was performed to account for the extent of liver resection and patient demographics. RESULTS LAD was performed in 545 (16%) cases. The most common indication for LAD was cholangiocarcinoma (CCA), followed by colorectal liver metastases (CRLM) and hepatocellular carcinoma (HCC). N+ status was found in 7 (8%), 59 (35%), and 56 cases (35%) for HCC, CCA, and CRLM, respectively (p < 0.001). The LAD rate was highest for robotic-assisted resections (28%) followed by open (26%) and laparoscopic resections (13%), whereas the number of resected lymph nodes was equivalent between the techniques (p = 0.303). LAD was associated with an increased risk of liver-specific postoperative complications, especially for patients with HCC. CONCLUSION In this multicenter registry study, LAD was found to be associated with an increased risk of liver-specific complications. The highest rate of LAD was observed among robotic liver resections.

Abstract
BACKGROUND The pathological tumor burden score (TBS) has been proven to be a better risk stratification tool for liver metastasis of colorectal cancer than the traditional clinical risk score (CRS). The aim of this study was to evaluate the prognostic value of the pathological tumor burden score in patients with or without neoadjuvant chemotherapy (NAC). METHODS A total of 348 patients with colorectal liver metastases (CRLM) who underwent curative hepatic resection were retrospectively enrolled from September 1999 to December 2016. Univariable and multivariable Cox regression analyses were conducted to identify the independent predictors of prognosis. Kaplan-Meier curves and log-rank tests were used to determine whether TBS has enough discriminatory ability under certain grouping. RESULTS Patients who received NAC had a higher median TBS than patients who did not receive NAC (4.07 vs. 2.69, P < 0.001). Among patients who did not receive NAC, those with TBS > 3 showed a significantly worse 3-year RFS (41.1% vs. 63.6%, P < 0.001) and 3-year OS rate (73.3% vs. 84.1%, P = 0.003) than those with TBS ≤ 3. Among the patients who received NAC, those with TBS ≤ 3 or TBS > 3 showed comparable 3-year RFS (33.3% vs. 26.4%, P = 0.400) and 3-year OS rates (76.5% vs. 58.2%, P = 0.064) to those who did not. Regardless of the regimen and response to NAC, there was no significant difference about 3-year RFS and 3-year OS rates between the TBS ≤ 3 and TBS > 3 groups. CONCLUSION Pathological TBS can be applied to predict the RFS and OS of patients suffering from CRLM who did not receive NAC. However, pathological TBS might not be regard as prognosis in patients who did receive NAC.

Abstract
Transplant oncology is a relatively new field in which transplantation is used to treat patients who would otherwise be unresectable. New anticancer treatment paradigms using tumor and transplant immunology and cancer immunogenomics are emerging. In turn, liver transplantation (LT) has become a potential therapy for certain patients with colorectal cancer (CRC) with liver metastasis, hepatocellular (HCC), cholangiocarcinoma (CCA), and metastatic neuroendocrine tumor (NET) of the liver. Although there are established criteria for LT in HCC, evidence regarding LT as a treatment modality for certain gastrointestinal malignancies is still debated. The aim of this review is to highlight updates in the role of LT for certain malignancies, including HCC, metastatic CRC, hilar CCA, and neuroendocrine tumor (NET), as well as contextualize LT use and discuss controversies in transplant oncology.

Abstract
BACKGROUND Colorectal cancer is a malignant tumor second only to lung and breast cancer in the West. The liver is the main target organ for colorectal cancer metastasis, affecting the prognosis and survival. Surgical treatment has made great progress in colorectal cancer liver metastasis , including radiofrequency ablation (RFA), high-intensity focused ultrasound (HIFU) ablation. OBJECT Clinical treatments for colorectal cancer liver metastases are not the same. In order to clarify the impact of surgical resection, RFA and HIFU, we provided a decision-making basis for the clinical treatment of colon cancer liver metastasis through systematic reviews and network meta-analysis (NMA). METHODS We systematically searched the Chinese and English databases: PubMed, Embase, CENTRAL, CINAHL, Web of Science, CNKI, CBM, VIP, Wan Fang. Literature screening, data extraction, and quality evaluation were carried out by two researchers, and finally, use Stata to carry out meta-analysis. RESULTS This study is ongoing and the results will be submitted to a peer-reviewed journal for publication. PROTOCOL REGISTRATION NUMBER INPLASY202150044.

Abstract
BACKGROUND AND OBJECTIVES Colorectal liver metastasis (CRLM) is a leading cause of morbidity and mortality in patients with colorectal cancer. Hepatic arterial infusion (HAI) chemotherapy has been demonstrated to improve survival in patients with resected CRLM and to facilitate conversion of technically unresectable disease. METHODS Between 2016 and 2018, n = 22 HAI pumps were placed for CRLM. All patients received systemic chemotherapy concurrently with HAI floxuridine/dexamethasone. Overall survival (OS) and progression-free survival (PFS) were assessed using the Kaplan-Meier method. RESULTS HAI pumps were placed in seven patients with completely resected CRLM and 15 patients with unresectable disease. Twenty-one patients received HAI floxuridine with a median of 5 total HAI cycles (interquartile range: 4-7). Biliary sclerosis was the most common HAI-related complication (n = 5, 24%). Of the 13 patients treated to convert unresectable CRLM, 3 (23%) underwent hepatic resection with curative intent after a median of 7 HAI cycles (range: 4-10). For all HAI patients, the mean OS was 26.7 months from CRLM diagnosis, while the median PFS and hepatic PFS from pump placement were 9 and 13 months, respectively. CONCLUSION Concomitant HAI and systemic therapy can be utilized at multidisciplinary programs for patients with advanced CRLM, both in the adjuvant setting and to facilitate conversion of unresectable disease.

Nontumor related risk score: A new tool to improve prediction of prognosis after hepatectomy for colorectal liver metastases. Surgery 2022; 171:1580-1587. [PMID: 35221105 DOI: 10.1016/j.surg.2022.01.030] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2021] [Revised: 01/20/2022] [Accepted: 01/23/2022] [Indexed: 02/06/2023]
Abstract
BACKGROUND Prognostic stratification of patients with colorectal cancer liver metastasis based solely on tumor-related factors has only moderate discriminatory ability. We hypothesized that the inclusion of nontumor related factors can improve prediction of long-term prognosis of patients with colorectal cancer liver metastasis. METHODS Nontumor related laboratory markers were assessed utilizing a training cohort from 2 U.S. institutions (n = 1,205). Factors independently associated with prognosis were used to develop a nontumor related prognostic score. The discriminatory ability, assessed by Harrell's C-statistics (C-index) and net reclassification improvement, was validated and compared with 3 commonly used tumor-related clinical risk scores: Fong clinical risk scores, m-clinical risk scores, and Genetic and Morphological Evaluation (GAME) score in an external validation cohort from 5 Asian (n = 1,307) and 3 European (n = 1,058) institutions. The discriminatory ability of nontumor related prognostic score combined with each of these 3 tumor-related prognostic scores was also estimated. RESULTS Alkaline phosphatase (hazard ratio 1.43; 95% confidence interval, 1.11-1.84), albumin (hazard ratio 0.71; 95% confidence interval, 0.57-0.89), and mean corpuscular volume (hazard ratio 19.0, per log unit; 95% confidence interval, 4.79-75.0) were each independently associated with increased risk of death after resection of colorectal cancer liver metastasis (all P < .05). In turn, alkaline phosphatase, albumin, and mean corpuscular volume were combined to form a nontumor related prognostic score (2.942 × mean corpuscular volume + 0.399 × alkaline phosphatase-0.339 × albumin-12) × 10 (median, 16; range, 1-30). The nontumor related prognostic score had good-to-modest discriminatory ability in the external cohort (C-index = 0.58), which was comparable to the 3 established tumor-related prognostic scores (C-index: Fong clinical risk scores, 0.53, m-clinical risk scores, 0.55, GAME, 0.58). The addition of the nontumor related prognostic score to the tumor-related prognostic scores enhanced the discriminatory ability in the entire study cohort (C-index: nontumor related score+Fong, 0.60, nontumor related score+m-clinical risk scores, 0.61, nontumor related score+GAME, 0.64), as well reclassification improvement (42.5, 42.7%, and 21.2%, respectively). CONCLUSION Nontumor related prognostic information may help improve the prognostic stratification of patients after resection of colorectal cancer liver metastasis. The nontumor related prognostic score may be combined with tumor-related prognostic tools to enhance prognostic stratification of patients with colorectal cancer liver metastasis.

Nomogram for predicting occurrence of synchronous liver metastasis in colorectal cancer: a single-center retrospective study based on pathological factors. World J Surg Oncol 2022; 20:39. [PMID: 35183207 PMCID: PMC8857813 DOI: 10.1186/s12957-022-02516-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2021] [Accepted: 02/10/2022] [Indexed: 11/10/2022] Open
Abstract
Abstract
Purpose
The purpose of this study was to explore the risk factors for synchronous liver metastasis (LM) of colorectal cancer (CRC) and to construct a nomogram for predicting the occurrence of synchronous LM based on baseline and pathological information.
Methods
The baseline and pathological information of 3190 CRC patients were enrolled in the study from the Department of Colorectal Surgery, the Second Affiliated Hospital of Harbin Medical University between 2012 and 2020. All patients were divided into development and validation cohorts with the 1:1 ratio. The characters of LM and none-LM patients in newly diagnosed colorectal cancer were utilized to explore the risk factors for synchronous LM with the univariate and multivariate logistic regression analyses. A predictive nomogram was constructed by using an R tool. In addition, receiver operating characteristic (ROC) curves was calculated to describe the discriminability of the nomogram. A calibration curve was plotted to compare the predicted and observed results of the nomogram. Decision-making curve analysis (DCA) was used to evaluate the clinical effect of nomogram.
Results
The nomogram consisted of six features including tumor site, vascular invasion (VI), T stage, N stage, preoperative CEA, and CA-199 level. ROC curves for the LM nomogram indicated good discrimination in the development (AUC = 0.885, 95% CI 0.854–0.916) and validation cohort (AUC = 0.857, 95% CI 0.821–0.893). The calibration curve showed that the prediction results of the nomogram were in good agreement with the actual observation results. Moreover, the DCA curves determined the clinical application value of predictive nomogram.
Conclusions
The pathologic-based nomogram could help clinicians to predict the occurrence of synchronous LM in postoperative CRC patients and provide a reference to perform appropriate metastatic screening plans and rational therapeutic options for the special population.

Abstract
BACKGROUND About 50% of the patients with colorectal adenocarcinoma will present with liver metastasis and 20% are synchronic. Liver resection is associated with improvement in survival in comparison to chemotherapy alone. AIM To analyze the overall survival in patients submitted to liver resection of colorectal cancer metastasis and prognostic factors related to the primary and secondary tumors. METHODS A retrospective analysis of a prospectively maintained database regarding demographic, primary tumor and liver metastasis characteristics. RESULTS There were 84 liver resections due to colorectal cancer metastasis in the period. The 5-year disease-free and overall survivals were 27.5% and 48.8% respectively. The statistically significant factors for survival were tumor grade (p=0.050), lymphovascular invasion (p=0.021), synchronous metastasis (p=0.020), as well as number (p=0.004), bilobar distribution (p=0.019) and diameter of the liver metastasis over 50 mm (p=0.027). Remained as independent negative predictive factors: lymphovascular invasion (HR=2.7; CI 95% 1.106-6.768; p=0.029), synchronous metastasis (HR=2.8; CI 95% 1.069-7.365; p=0.036) and four or more liver metastasis (HR=1.7; CI 95% 1.046-2.967; p=0.033). CONCLUSION The resection of liver metastasis of colorectal adenocarcinoma leads to good survival rates. Lymphovascular invasion was the single prognostic factor related to the primary tumor. Synchronous disease and four or more metastasis were the most significant factors related to the secondary tumor.

Abstract
Background The simultaneous resection of synchronous colorectal cancer liver metastasis (SCRLM) has been widely applied. It is necessary to establish a risk scoring system to predict post-operative recurrence, especially in patients with neoadjuvant treatment. Methods The medical records of 221 patients undergoing simultaneous resection of CRLM were assessed in this study with a further 128 patients allocated to a validation group. All patients in the study group were classified according to their history of neoadjuvant treatment and univariate and multivariate analyses were applied to study independent risk factors. A score model was then generated according to the factors included. Our data set were also applied to validate three other existing scoring models [Fong clinical recurrence score (CRS), Konopke, and Zakaria disease-free survival (DFS) score], and the concordance index was calculated for comparison among these models. Results CRLM involving more than three nodes positive for a primary tumor was considered an independent risk factor for progression in patients without neoadjuvant treatment and all score models could discretely stratify patients according to disease free survival. In patients receiving neoadjuvant treatment, CRLM involving more than one node and transfusion invasion were major determinants in patients after treatment. However, only our scoring system and Fong’s CRS score could discretely discriminate patients. In the validation group, patients were significantly classified with the score system. Conclusions Existing score models had better values for determining prognosis in patients with SCRLM, especially in those undertaking neoadjuvant treatment. Larger cohorts, along with more detailed clinical features and multicenter validation should be undertaken before utilization.

Abstract
BACKGROUND An individualized treatment decision is based on the accurate evaluation of clinical risk factors and prognosis for resectable colorectal liver metastases. The current study aimed to develop an effective nomogram to predict progression-free survival (PFS) and to design a treatment schedule preoperatively. METHODS The study enrolled a primary cohort of 532 patients with resectable colorectal liver metastases (CRLM) who underwent hepatic resection at two institutions and a validation cohort of 237 patients at two additional institutions with resectable CRLM between 1 January 2008 and 31 December 2018. A nomogram was created based on the independent predictors in the multivariable analysis of progression-free survival in the primary cohort. The predictive accuracy and discriminative ability of the nomogram were determined by the concordance index (C-index) and the calibration curve. The score was compared with the current standard Fong score and validated with an external cohort. RESULTS The independent risk factors for CRLM patients identified in the multivariable analysis were tumor larger than 5 cm, more than one tumor, RAS mutation, primary lymph node metastasis, and primary tumor located on the right side. All five factors were considered in the nomogram. The C-index of the nomogram for predicting survival was 0.696. With external validation, the C-index of the nomogram for the prediction of the PFS was 0.682, which demonstrated that this model has a good level of discriminative ability. For high-risk patients (score > 16), neoadjuvant chemotherapy improved PFS and overall survival (OS) after hepatic resection. CONCLUSION The current nomogram demonstrated an accurate performance in predicting PFS for resectable CRLM patients with liver-limited disease. Based on the current nomogram, high-risk patients (nomogram score > 16) might benefit from neoadjuvant chemotherapy.

Abstract
BACKGROUND Given the poor synthetic function of cirrhotic liver, successful resection for patients with hepatocellular carcinoma (HCC) necessitates the ability to achieve resections with tumor free margins. AIM To validate post hepatectomy liver failure score (PHLF), compare it to other established systems and to stratify risks in patients with cirrhosis who underwent curative liver resection for HCC. METHODS Between December 2010 and January 2017, 120 patients underwent curative resection for HCC in patients with cirrhosis were included, the pre-operative, operative and post-operative factors were recorded to stratify patients' risks of decompensation, survival, and PHLF. RESULTS The preoperative model for end-stage liver disease (MELD) score [odds ratio (OR) = 2.7, 95%CI: 1.2-5.7, P = 0.013], tumor diameter (OR = 5.4, 95%CI: 2-14.8, P = 0.001) and duration of hospital stay (OR = 2.5, 95%CI: 1.5-4.2, P = 0.001) were significant independent predictors of hepatic decompensation after resection. While the preoperative MELD score [hazard ratio (HR) = 1.37, 95%CI: 1.16-1.62, P < 0.001] and different grades of PHLF (grade A: HR = 2.33, 95%CI: 0.59-9.24; Grade B: HR = 3.15, 95%CI: 1.11-8.95; Grade C: HR = 373.41, 95%CI: 66.23-2105.43; P < 0.001) and HCC recurrence (HR = 11.67, 95%CI: 4.19-32.52, P < 0.001) were significant independent predictors for survival. CONCLUSION Preoperative MELD score and tumor diameter can independently predict hepatic decompensation. While, preoperative MELD score, different grades of PHLF and HCC recurrence can precisely predict survival.

Abstract
PURPOSE To assess whether CT-based radiomics of the ablation zone (AZ) can predict local tumour progression (LTP) after thermal ablation for colorectal liver metastases (CRLM). MATERIALS AND METHODS Eighty-two patients with 127 CRLM were included. Radiomics features (with different filters) were extracted from the AZ and a 10 mm periablational rim (PAR)on portal-venous-phase CT up to 8 weeks after ablation. Multivariable stepwise Cox regression analyses were used to predict LTP based on clinical and radiomics features. Performance (concordance [c]-statistics) of the different models was compared and performance in an 'independent' dataset was approximated with bootstrapped leave-one-out-cross-validation (LOOCV). RESULTS Thirty-three lesions (26 %) developed LTP. Median follow-up was 21 months (range 6-115). The combined model, a combination of clinical and radiomics features, included chemotherapy (HR 0.50, p = 0.024), cT-stage (HR 10.13, p = 0.016), lesion size (HR 1.11, p = <0.001), AZ_Skewness (HR 1.58, p = 0.016), AZ_Uniformity (HR 0.45, p = 0.002), PAR_Mean (HR 0.52, p = 0.008), PAR_Skewness (HR 1.67, p = 0.019) and PAR_Uniformity (HR 3.35, p < 0.001) as relevant predictors for LTP. The predictive performance of the combined model (after LOOCV) yielded a c-statistic of 0.78 (95 %CI 0.65-0.87), compared to the clinical or radiomics models only (c-statistic 0.74 (95 %CI 0.58-0.84) and 0.65 (95 %CI 0.52-0.83), respectively). CONCLUSION Combining radiomics features with clinical features yielded a better performing prediction of LTP than radiomics only. CT-based radiomics of the AZ and PAR may have potential to aid in the prediction of LTP during follow-up in patients with CRLM.

Abstract
INTRODUCTION Two novel clinical risk scores (CRS) that incorporate KRAS mutation status were developed: modified CRS (mCRS) and GAME score. However, they have not been tested in large national and international cohorts. The aim of this study was to validate the prognostic discrimination utility and determine the clinical usefulness of the two novel CRS. METHODS Patients undergoing hepatectomy for CRLM (2000-2018) in 10 centers were included. The discriminatory abilities of mCRS, GAME, and Fong CRS were evaluated using Harrell's C-index and Akaike's Information Criterion. RESULTS In the entire cohort, the C-index of the GAME score (0.61) was significantly higher than those of Fong score (0.57) and mCRS (0.54), while the C-Index of mCRS was significantly lower than that of Fong score. When we compared the models in the various geographical regions, the C-index of GAME score was significantly higher than that of mCRS in North America, Europe, and South America. The AIC of Fong score, mCRS, and GAME score were 14 405, 14 447, and 14 319, respectively. CONCLUSION In conclusion, using the largest and most heterogenous population of CRLM patients with known KRAS status, this independent, external validation demonstrated that the GAME score outperforms both the traditional Fong score and mCRS.

Abstract
BACKGROUND AND OBJECTIVES The histological growth pattern (HGP) represents a strong prognostic factor in patients undergoing surgery for colorectal liver metastases (CRLM). We evaluated whether the combination of HGP with clinico-metabolic parameters could improve its prognostic value. METHODS In a series of 108 patients undergoing resection of CRLM, the HGP of CRLM was scored according to international guidelines. Baseline clinico-metabolic clinical status was evaluated using a metabolic-Clinical Risk Score (mCRS), combining traditional Memorial Sloan Kettering-CRS parameters with the tumor-to-liver glucose uptake ratio as measured with 18 Fluorodeoxyglucose/positron emission tomography. RESULTS In patients with desmoplastic HGP (DHGP) CRLM (20% of all patients), 5- and 10-years overall survival (OS) and disease free survival (DFS) were 66% and 43% and 37% and 24.5%, as compared with 35% and 21% and 11% and 11% in the non-DHGP group (p = 0.07 and 0.054). Among DHGP patients, those with a low-risk mCRS had improved postoperative outcomes, 5- and 10-years OS and DFS reaching 83.3% and 62.5% and 50% and 33%, as compared with 18% and 0% and 0% and 0% in high-risk mCRS patients (p = 0.007 and 0.003). In contrast, mCRS did not influence postoperative survivals in non-DHGP patients. CONCLUSIONS Combining the clinico-metabolic characteristics with the HGP may improve prognostication in patients undergoing surgery for CRLM.

Development of a Metastasis-Related Immune Prognostic Model of Metastatic Colorectal Cancer and Its Usefulness to Immunotherapy. Front Cell Dev Biol 2021; 8:577125. [PMID: 33585439 PMCID: PMC7876250 DOI: 10.3389/fcell.2020.577125] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2020] [Accepted: 10/30/2020] [Indexed: 12/30/2022] Open
Abstract
Background: Post-surgical recurrence of the metastatic colorectal cancer (mCRC) remains a challenge, even with adjuvant therapy. Moreover, patients show variable outcomes. Here, we set to identify gene models based on the perspectives of intrinsic cell activities and extrinsic immune microenvironment to predict the recurrence of mCRC and guide the adjuvant therapy. Methods: An RNA-based gene expression analysis of CRC samples (total = 998, including mCRCs = 344, non-mCRCs = 654) was performed. A metastasis-evaluation model (MEM) for mCRCs was developed using the Cox survival model based on the prognostic differentially expressed genes between mCRCs and non-mCRCs. This model separated the mCRC samples into high- and low-recurrence risk clusters that were tested using machine learning to predict recurrence. Further, an immune prognostic model (IPM) was built using the COX survival model with the prognostic differentially expressed immune-related genes between the two MEM risk clusters. The ability of MEM and IPM to predict prognosis was analyzed and validated. Moreover, the IPM was utilized to evaluate its relationship with the immune microenvironment and response to immuno-/chemotherapy. Finally, the dysregulation cause of IPM three genes was analyzed in bioinformatics. Results: A high post-operative recurrence risk was observed owing to the downregulation of the immune response, which was influenced by MEM genes (BAMBI, F13A1, LCN2) and their related IPM genes (SLIT2, CDKN2A, CLU). The MEM and IPM were developed and validated through mCRC samples to differentiate between low- and high-recurrence risk in a real-world cohort. The functional enrichment analysis suggested pathways related to immune response and immune system diseases as the major functional pathways related to the IPM genes. The IPM high-risk group (IPM-high) showed higher fractions of regulatory T cells (Tregs) and smaller fractions of resting memory CD4+ T cells than the IPM-low group. Moreover, the stroma and immune cells in the IPM-high samples were scant. Further, the IPM-high group showed downregulation of MHC class II molecules. Additionally, the Tumor Immune Dysfunction and Exclusion (TIDE) algorithm and GDSC analysis suggested the IPM-low as a promising responder to anti-CTLA-4 therapy and the common FDA-targeted drugs, while the IPM-high was non-responsive to these treatments. However, treatment using anti-CDKN2A agents, along with the activation of major histocompatibility complex (MHC) class-II response might sensitize this refractory mCRC subgroup. The dysfunction of MEIS1 might be the reason for the dysregulation of IPM genes. Conclusions: The IPM could identify subgroups of mCRC with a distinct risk of recurrence and stratify the patients sensitive to immuno-/chemotherapy. Further, for the first time, our study highlights the importance of MHC class-II molecules in the treatment of mCRCs using immunotherapy.

Abstract
Objectives To develop and validate predictive nomograms of cancer specific survival (CSS) and overall survival (OS) for synchronous colon cancer with liver metastasis (SCLM) patients. Methods Patients with pathologically diagnosed colon cancer with liver metastasis were retrieved from the SEER database between 2010 and 2015. Only SCLM patients were included. Univariate and multivariate cox regression analyses were conducted to identify the potential predictors of patients’ survival outcomes. The selected variables were integrated to create predictive nomograms via R tools. Furthermore, the concordance index Harrell’s C statistic (C-index) was calculated to describe the discrimination of nomograms. Calibration (1000 bootstrap resamples) curves were plotted to compare the predictions of nomograms with the observed outcomes. Decision curve analysis (DCA) and clinical impact curves were performed to evaluate the clinical effects of nomograms. Results A total of 22,378 SCLM patients were included. The median time of OS and CSS was 13 and 17 months, respectively. The 1-, 2-, and 3-year rate of OS was 50.6, 28.1, and 14.8%, respectively. While the 1-, 2-, and 3-year rate of CSS was 58.7, 36.8, and 22.5%, respectively. SCLM patients with increased age, left primary tumor location, AJCC IVb stage, and no chemotherapy were associated with an obviously reduced OS and CSS. Variables including age, histological grade, T/N/M stage, tumor size, bone/lung metastasis, CEA, surgery of primary site, and chemotherapy were closely related to the prognoses of SCLM patients. Nomograms of OS and CSS were built and displayed online for convenient utilization. The C-index of OS and CSS monograms were 0.74 and 0.73, respectively, indicating relatively good discrimination of the nomograms. The calibration curves suggested a good agreement between the actual observation and the nomogram prediction. DCAs and clinical impact curves reflected favorable potential clinical effects of predictive nomograms. Conclusion Chemotherapy, surgery of primary site, and age were important independent risk factors for the CSS and OS of SCLM patients. We built and validated two reliable nomograms of OS and CSS to predict the prognoses of SCLM patients, which can be accessed online at (https://predictive-tool.shinyapps.io/CSS-DynNomapp/; https://predictive-tool.shinyapps.io/OS-DynNomapp/).

Postoperative liver regeneration does not elicit recurrence of colorectal cancer liver metastases after major hepatectomy. Surg Oncol 2020; 35:24-33.

Abstract
BACKGROUND AND OBJECTIVES Recurrence is a frequent concern in curatively resected CRC liver metastases. Translational research suggests that regeneration upon hepatectomy may also alleviate metastatic recurrence; however, the significance in patients is unclear. We therefore sought to study the effect of liver regeneration on tumor recurrence in patients. METHODS In this retrospective cohort study, we included 58 out of 186 potentially eligible patients from our prospectively maintained database of CRC liver metastasis patients between 2001 and 2012 with a median follow-up of 42 months who underwent a formal right or left hemihepatectomy. Liver regeneration in CT volumetry was correlated with recurrence of CRC liver metastases and overall survival. RESULTS Liver regeneration increased up to 14 months to 21.0% for left and 122.6% for right hemihepatectomy, respectively, with comparable final volumes. Regeneration was independent of initial tumor stage, number of metastases, and preoperative chemotherapy. Patients with lower liver regeneration showed earlier recurrence of CRC liver metastases (p = 0.006). Overall survival did not differ in patients with weak versus strong liver regeneration. CONCLUSIONS The extent of liver regeneration after major hepatectomy does not impede overall survival. Therefore, our data encourage aggressive therapeutical regimes for CRC liver metastases involving major hepatectomies as part of a curative approach.

Abstract
Liver transection is the most challenging part of hepatectomy due to the risk of hemorrhage which is associated with postoperative morbidity and mortality and reduced long-term survival. Parenchymal ultrasonic dissection (UD) with bipolar coagulation (BPC) has been widely recognized as a safe, effective, and standard technique during open and laparoscopic hepatectomy. We here introduce our technique of robotic liver transection using UD with BPC and report on short-term perioperative outcomes. From a single-institution prospective liver surgery database, we identified patients who underwent robotic liver resection. Demographic, anesthetic, perioperative, and oncologic data were analyzed. Fifty patients underwent robotic liver resection using UD and BPC for liver malignancies (n = 42) and benign lesions (n = 8). The median age of the patients was 67 years and 28 were male. According to the difficulty scoring system, 60% (n = 30) of liver resection were considered difficult. Three cases (6%) were converted to open surgery. The median operative time was 240 min, and the median estimated blood loss was 200 ml; 2 patients required operative transfusions. The overall complication rate was 38% (grade I, 29; grade II, 15; grade III, 3; grade IV, 1). Seven patients (14%) experienced biliary leakage. The median length of hospital stay post-surgery was 7 (range 3-20) days. The R0 resection rate was 92%. Robotic parenchymal transection using UD and irrigated BPC appears a simple, safe, and effective technique. However, our results must be confirmed in larger series or in randomized controlled trials.

Abstract
Clinically, a considerable portion of patients with early T stage who were supposed to have a low distant metastatic probability were diagnosed with metastatic liver colorectal cancer (CRLM). Our study aims to evaluate the prognostic value of the T stage for metastatic patients and establish a convenient individual assessment model for clinicians to explore preoperative predictors. The mRNA profiles of colorectal tumors (N = 19) were obtained by microarray at our clinical center. A total of 5,618 patients with CRLM from 2010 to 2015 were enrolled for the Surveillance, Epidemiology, and End Results (SEER) database. The cDNA microarray analyses showed that gene expression pattern in the T2N0M1 subgroup was significantly different from the T3/4N0M0 subgroup. In the survival analysis, metastatic patients with T1 stage surprisingly had much poorer prognosis than those with T3/T4 stage. Specifically, metastatic patients with early T stage were observed with higher frequency occurring at the rectum, better differentiation, less metastases in the lymph nodes, and a higher CEA level. Further survival analysis indicated that early T classification was an independent prognostic factor for a poor survival. When the lymph node (N) status was taken into consideration, patients with T1/2N+ had better survival than T1/2N0 patients. A clinical nomogram was constructed based on preoperative factors. The calibration curves showed a good concordance between nomogram prediction and actual observation. In conclusion, CRLM with early T stage had a different biological background. The prognosis of patients at T1/2M1 was poorer than at T3/4M1. More attention should be paid to the surveillance of high-risk factors and the screening of early T stage.

Abstract
This meta-analysis was conducted to evaluate the effectiveness and safety of infrahepatic inferior vena cava clamping combined with the Pringle maneuver during. hepatectomies. Clinical studies were retrieved from the PubMed, Embase, Cochrane Library, Medline and Web of Science databases. Study-specific effect sizes and their 95% confidence intervals (CIs) were combined to calculate the pooled value using a fixed-effects or random-effects model.Nine studies with 1008 patients in total were included. The infrahepatic inferior vena cava clamping combined with Pringle maneuver group experienced less total operative blood loss (mean difference [MD] = -327.11; 95% CI: -386.50-267.72; P < 0.00001), less blood loss during transection (MD = -270.19; 95% CI: -344.99-195.38; P < 0.00001), fewer blood transfusions (odds ratio [OR] = 0.36; 95% CI: 0.25-0.53;P < 0.00001) and fewer postoperative complications (OR = 0.70; 95% CI: 0.52-0.95; P = 0.02) than did the control group. Operative time (MD = 8.54; 95% CI: 4.68-12.40; P < 0.0001) was similar in both groups. liver transection time,hospital stay, postoperative liver function and renal function did not differ between groups.Applying infrahepatic inferior vena cava clamping combined with the Pringle maneuver can effectively reduce intraoperative bleeding, blood transfusion rates, and postoperative complications, while adding minimal time to the operation.

Different variables predict the outcome of patients with synchronous versus metachronous metastases of colorectal cancer. Clin Transl Oncol 2020; 22:1399-1406. [PMID: 31916018 DOI: 10.1007/s12094-019-02277-7] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2019] [Accepted: 12/17/2019] [Indexed: 02/07/2023]
Abstract
PURPOSE Timing of metastasis is a controversial prognostic factor for patients with metastatic colorectal cancer (mCRC), as well as the performance of the common prognostic variables within patients with synchronous (SMs) or metachronous metastases (MMs). The aim of the current study is to evaluate outcome by the timing of metastases and to explore different tumor characteristics associated with SMs and MMs. METHODS Data were collected from the clinical records of patients with mCRC, which were referred to the Department of Oncology of the Ospedale Civile di Sanremo from 2006 to 2011. A comparison of the characteristics of tumors of patients, overall and by the timing of metastases, and a Cox regression analysis have been performed to select the most relevant prognostic factors. Finally, the characteristics of the variables associated with the outcome were analyzed through a logistic regression. RESULTS Two hundreds fifteen patients with SMs and two hundreds ten with MMs were included. Patients with SMs reported a poor prognosis (18.5 versus 62.8 months; p value < 0.001). Among patients with SMs there was a significant difference in overall survival between patients with a CEA-positive or negative disease, while no difference was present among patients with MMs. After multivariate analysis, only within the SMs group the occurrence of liver metastases was related to a CEA-positive disease. CONCLUSIONS Within the cohort of SMs high CEA levels, occurrence of liver metastases and right-sided colon tumors were associated with a very poor prognosis, whereas no relationship was detectable in the group of patients with MMs.

Abstract
OBJECTIVE The aim of this study was to evaluate outcomes of metastases at various time intervals after colorectal cancer (CRC) diagnosis. BACKGROUND Earlier studies have indicated a short time interval between CRC diagnosis and distant metastases to be associated with poor prognosis. The majority of studies assessed outcome from CRC diagnosis or metastasis resection rather than from metastasis diagnosis and might be subject to immortal time bias. METHODS Patients in the population-based DACHS study were stratified: metastases at/within 1 month (immediate), 2 to 6 months (early), 7 to 12 months (intermediate), and >12 months (late) after CRC diagnosis. The primary endpoint was overall survival (OS) from metastasis diagnosis. Cox proportional hazards regression models were used to calculate hazard ratios (HRs) and 95% confidence intervals (CI). HRs were adjusted for important confounders and immortal time. RESULTS A total of 1027 patients were included. T4 (P < 0.0001) and node-positive tumors (P < 0.0001) were more frequent in the immediate group. Lung metastases (P < 0.0001) and single-site metastases (P < 0.0001) were more prevalent in the late group. In multivariable analysis, immediate metastases were not associated with poor OS compared to metastases at later time points (late vs immediate: HR 1.21; 95% CI, 0.98-1.48). Subgroup analyses revealed poor OS of late versus immediate metastases for females (1.45; 1.08-1.96), proximal colon cancer (1.54; 1.09-2.16), and N0 (1.46; 1.00-2.12) or N1 disease (1.88; 1.17-3.05). CONCLUSIONS Immediate or early metastases are not associated with unfavorable outcome compared to late metastases. These findings challenge the current notion of poor outcome for CRC with immediate or early metastases.

Abstract
Although chemotherapy for treating colorectal cancer has had some success, drug resistance and metastasis remain the major causes of death for colorectal cancer patients. MicroRNA-21-5p (hereafter denoted as miR-21) is one of the most abundant miRNAs in human colorectal cancer. A Kaplan-Meier survival analysis found a negative prognostic correlation of miR-21 and metastasis-free survival in colorectal cancer patients (The Cancer Genome Atlas Colon Adenocarcinoma/TCGA-COAD cohort). To explore the role of miR-21 overexpression in drug resistance, a stable miR-21-overexpressing clone in a human DLD-1 colorectal cancer cell line was established. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) cell viability assay found that miR-21 overexpression induced drug resistance to topoisomerase inhibitors (SN-38, doxorubicin, and etoposide/VP-16). Mechanistically, we showed that miR-21 overexpression reduced VP-16-induced apoptosis and concomitantly enhanced pro-survival autophagic flux without the alteration of topoisomerase expression and activity. Bioinformatics analyses suggested that miR-21 overexpression induced genetic reprogramming that mimicked the gene signature of topoisomerase inhibitors and downregulated genes related to the proteasome pathway. Taken together, our results provide a novel insight into the role of miR-21 in the development of drug resistance in colorectal cancer.

Abstract
Background Many studies have investigated the prognostic role of biomarkers in colorectal liver metastases (CRLM). However, no biomarker has been established in routine clinical practice. The aim of this study was to scrutinize the current literature for biomarkers evaluated by immunohistochemistry as prognostic markers in patients with resected CRLM. Methods A systematic review was performed according to the PRISMA guidelines. Articles were identified in the PubMed database with selected search terms and by cross-references search. The REMARK quality criteria were applied. Markers were included if they reported the prognostic impact of immunohistochemical markers in a multivariable setting in relation to overall survival (OS). A meta-analysis was conducted when more than one original article provided survival data of a marker. Results In total, 26 biomarkers were identified as independent significant markers for OS in resected CRLM. These biomarkers were found to be involved in multiple oncogenic signalling pathways that control cell growth, apoptosis, angiogenesis and evasion of immune detection. Among these biomarker candidates were Ki-67, EGFR, p53, hTERT, CD34, TSP-1, KISS1, Aurora kinase A and CDX2. CD34 and TSP-1 were reported as significantly associated with survival by more than one study and where therefore pooled in a meta-analysis. Conclusion A number of independent prognostic biomarkers for resected CRLM were identified. However, most markers were evaluated in a retrospective setting with small patient cohorts, without external validation. Large, prospective, multicentre studies with standardised methods are needed before biomarkers can translated into the clinic.

Abstract
Metastases cause recurrence and mortality for patients with colorectal carcinomas (CRC). In present study, we evaluated heterogeneity on drug resistance and its underlying mechanism between metastatic and primary CRC. Immunohistochemical results from clinical tissue microarray (TMA) suggested that the expression concordance rates of cancer stem cells (CSCs) and drug resistance relative proteins between lymph-node metastatic and primary CRC foci were low. The apoptotic and proliferation indexes in metastasis CRC specimens were decreased compared with primary. In vitro experimental results indicated that the migration and invasion abilities were upregulated in metastatic cells SW620 compared with primary cells SW480, the cellular efflux ability and WNT/β-catenin activity were also upregulated in SW620 cells. After 5-fluorouracil (5-Fu) treatment, the reduction in the proportion of cell apoptosis, CD133 and TERT expression levels in SW620 were lower than that in SW480 cells. Bioinformatics analysis in whole-genome transcriptional profiling results between metastatic and primary CRC cells suggested that differentially expressed genes were mainly centered on well-characterized signaling pathways including WNT/β-catenin, cell cycle and cell junction. Collectively, heterogeneity of drug resistant was present between metastatic and primary CRC specimens and cell lines, the abnormal activation of WNT/β-catenin signaling pathway could be a potential molecular leading to drug resistant ability enhancing in metastatic CRC cells.

Abstract
BACKGROUND There is urgent need for improved staging in patients with metastatic colorectal cancer (mCRC). In this study, we evaluated the prognostic value of circulating endothelial cells (CEC) in comparison with circulating tumor cells (CTC) in patients with mCRC amenable for potentially curative surgery. METHODS A total of 140 patients were enrolled prospectively. CTC and CEC were measured with the CellSearch System (Veridex, NJ, USA). Cut-off values were determined using ROC analyses. Prognostic factors were identified by Cox proportional hazards models. RESULTS ROC analyses revealed ≥ 21 CEC as cut-off levels for detection, which was present in 68 (49%). CEC detection was associated with female gender (p = 0.03) only, whereas CTC detection was associated with presence of the primary tumor (p = 0.007), metastasis size (p < 0.001), bilobar liver metastases (p = 0.02), CEA (p < 0.001) and CA 19-9 levels (p < 0.001). On multivariate analysis only CEC detection (HR 1.81; p = 0.03) and preoperative CA19-9 levels (HR 2.28, p = 0.005) were revealed as independent predictors of poor survival. CONCLUSIONS CEC are of stronger prognostic value than CTC. Further studies are required to validate these results and to evaluate CEC as predictive biomarker for systemic therapy alone as well as in combination with other markers such as CA19-9.

Abstract
AIM To investigate the role of thymidylate synthase (TS) as a predictive biomarker in patients with resected colorectal liver metastases (CRLM). MATERIALS & METHODS PubMed, EMBASE and Cochrane Library were queried up to June 2017. Meta-analysis was performed using random-effects model. Risk of bias was assessed using funnel plots. RESULTS Six eligible studies were included, comprising a total of 542 patients. Meta-analysis demonstrated a trend to reduced overall survival in patients with resected CRLM with TS overexpression, with a hazard ratio of 1.13 (95% CI: 0.99-1.29; p = 0.08). In three studies where patients received systemic fluorouracil, the pooled hazard ratio was 2.25 (95% CI: 1.37-3.71; p = 0.001). CONCLUSION TS appears to be a clinically relevant predictive biomarker in patients with resected CRLM receiving systemic 5-FU.

Abstract
BACKGROUND The prognosis of patients undergoing liver resection for colorectal liver metastases (CLM) seems to be altered when the primary tumour is right-sided. However, data are lacking and conflicting. We aimed to evaluate the influence of the primary tumour location on oncologic outcomes following such surgery. METHODS We retrospectively analysed prospectively collected data from 376 consecutive patients who underwent liver surgery for CLM between June 2010 and August 2015. We compared the outcomes of patients with right colon tumours and those with left colorectal tumours. The splenic flexure was used as the cut-off point to determine the anatomic primary site. RESULTS Among the 364 patients eligible, 74 (20.3%) had a right-sided primary tumour. These patients were older, had a poorer American Society of Anaesthesiologists status and had fewer node-positive primary tumours. The CLM characteristics were similar between both groups. Median PFS was not significantly different between the two groups at 9.9 months, as well as the pattern of recurrence. Median OS was shorter for patients with right-sided primary tumour (34.6 versus 45.3 months, p = 0.035). Similar results were observed when patients with rectal tumour were excluded from analysis (34.6 vs. 47.5 months, p = 0.007). Primary tumour site was an independent prognosis factor in multivariate analysis. CONCLUSION Right-sided location of the primary tumour is associated with worse OS after surgery for CLM, but seems to have no influence on PFS, and on the pattern of recurrence.

Abstract
Numerous factors affect the prognosis of colorectal liver metastasis (CRLM) patients after hepatic resection. We investigated several factors related to overall survival in patients with CRLM to identify those most likely to benefit from hepatic resection, and produced a rational tumor biology score system. Three hundred CRLM patients treated with preoperative chemotherapy followed by hepatic resection between 2006 and 2016 were enrolled in our study. Clinicopathologic and long-term survival data were collected and assessed. Patient 1-, 3-, and 5-year overall survival rates were 92.7%, 58.3%, and 45.8%, respectively, while 1-, 3-, and 5-year disease-free survival rates were 44.7%, 28.6%, and 24.2%, respectively. Multivariate Cox regression analysis revealed poor preoperative chemotherapy response, Fong clinical risk score > 2, and KRAS mutation to be independent prognostic indicators in CRLM patients. As part of a preoperative staging system in which one point was assigned for each factor, a total score (out of 3) was predictive of long-term survival following surgery. These factors facilitate personalized prognostic assessments in CRLM patients planning for resection.

Abstract
Integrating diverse types of prognostic information into accurate, individualized estimates of outcome in colorectal cancer is challenging. Significant heterogeneity in colorectal cancer prognostication tool quality exists. Methodology is incompletely or inadequately reported. Evaluations of the internal or external validity of the prognostic model are rarely performed. Prognostication tools are important devices for patient management, but tool reliability is compromised by poor quality. Guidance for future development of prognostication tools in colorectal cancer is needed.

Abstract
BACKGROUND AND OBJECTIVES There is ongoing debate about whether patients planned for liver resection of colorectal liver metastases (CRLM) benefit from neoadjuvant chemotherapy (NC). Therefore, we performed a retrospective survival analysis of patients with and without NC prior to surgery. METHODS Data prospectively collected from 468 consecutive patients were analyzed in a retrospective design. We performed a survival analysis and added propensity score matching (PSM). Univariate and multivariate analysis was performed to determine independent prognostic risk factors. RESULTS NC was performed in 145/468 patients. NC did not have a significant influence on overall survival (OS) either before or after PSM. Patients receiving NC showed increased complication rates, especially concerning non-surgical complications after primary resection (P = 0.025) of CRLM. Multivariate analysis before and after PSM revealed that the Memorial Sloan Kettering Cancer Center (MSKCC) score and CEA values are strong predictors for OS in patients with CRLM. CONCLUSIONS NC was not associated with increased OS in patients suffering from CRLM. Additionally, potentially harmful chemotherapy prior to surgery increases the risk of postoperative complications in these patients.

Survival after associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) for advanced colorectal liver metastases: A case-matched comparison with palliative systemic therapy. Surgery 2016; 161:909-919. [PMID: 28038862 DOI: 10.1016/j.surg.2016.10.032] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2016] [Revised: 10/06/2016] [Accepted: 10/19/2016] [Indexed: 12/17/2022]
Abstract
BACKGROUND Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) allows the resection of colorectal liver metastases with curative intent which would otherwise be unresectable and only eligible for palliative systemic therapy. This study aimed to compare outcomes of ALPPS in patients with otherwise unresectable colorectal liver metastases with matched historic controls treated with palliative systemic treatment. METHODS All patients with colorectal liver metastases from the international ALPPS registry were identified and analyzed. Survival data were compared according to the extent of disease. Otherwise unresectable ALPPS patients were defined by at least 2 of the following criteria: ≥6 metastasis, ≥2 future remnant liver metastasis, ≥6 involved segments excluding segment 1. These patients were matched with patients included in 2, phase 3, metastatic, colorectal cancer trials (CAIRO and CAIRO2) using propensity scoring in order to compare survival. RESULTS Of 295 patients with colorectal liver metastases in the ALPPS registry, 70 patients had otherwise unresectable disease defined by the proposed criteria. Two-year overall survival was 49% and 72% for patients with ≥2 and <2 criteria, respectively (P = .002). Median disease-free survival was 6 months compared to 12 months (P < .001) in the ≥2 and <2 criteria groups, respectively. Median overall survival was comparable between ALPPS patients with ≥2 criteria and case-matched patients who received palliative treatment (24.0 vs 17.6 months, P = .088). CONCLUSION Early oncologic outcomes of patients with advanced liver metastases undergoing ALPPS were not superior to results of matched patients receiving systemic treatment with palliative intent. Careful patient selection is essential in order to improve outcomes.

Abstract
OBJECTIVE The aim of this study was to validate clinical risk scores in patients underwent laparoscopic resection of colorectal liver metastases (CLM) with 5 years follow-up or more, and assess 5- and 10-year actual survival in this group. METHODS A total of 516 laparoscopic liver resections were performed in 406 patients with CLM between February 1998 and September 2015. A follow-up of 5 and 10 years could be assessed in 144 and 29 patients, respectively. The Fong score, pre- and postoperative Basingstoke Predictive Index (BPI), Nordlinger score, and Iwatsuki score were validated. RESULTS Five- and ten-year cancer-related actual survival was 54% and 32%, respectively. The Fong score, pre- and postoperative BPI and the Nordlinger score divided patients into risk groups with significant difference in survival between the groups. However, predicted 5-year survival rates were lower than the actual 5-year survival (mean difference in 17%,13%, 20%, and 30%, respectively). CONCLUSION The Fong score, pre- and postoperative BPI and the Nordlinger score systems can be used to predict survival for laparoscopically operated patients in the era of multimodal-treatment after adjusting of survival rates. The actual five- and 10-year survival after laparoscopic resection of CLM is similar to results previously published for open liver resection. J. Surg.

Abstract
Purpose The hepatic resection is the gold-standard treatment for patients with colorectal-cancer liver metastases (CLM). This study aimed to identify prognostic factors in patients with synchronous CLM who underwent a surgical curative (R0) resection with respect to the number of metastatic nodules. Methods Of 1,261 CLM patients treated between January 1991 and December 2010, 339 who underwent a R0 resection for synchronous CLM were included in this retrospective analysis. Patients were grouped according to the number of CLM nodules: 1–2 CLM nodules, n = 272 (group 1) and 3–8 CLM nodules, n = 67 (group 2). Results The 5-year progression-free survival (PFS) rate in group 1was better than that in group 2 (P = 0.020). The multivariate analysis identified lymph-node metastasis (N2), lymphovascular invasion (LVI), and three or more CLM nodules as independent poor prognostic factors for PFS in all patients and lymph-node metastasis (N2) and LVI as independent poor prognostic factors for patients in group 1. No independent prognostic factors were identified for patients in group 2. CLM treatment method and neoadjuvant chemotherapy were not associated with survival. Conclusion Three or more metastatic nodules, lymph-node metastasis (N2), and LVI were independent poor prognostic factors for PFS in patients with synchronous CLM who underwent a R0 resection. The latter 2 factors were also independent prognostic factors for PFS in patients with less than 3 CLM nodules; however, in patients with three or more CLM nodules, the prognosis for PFS may be related only to liver metastasis.

Abstract
BACKGROUND Investigations regarding the impact of tumor biology after surgical management of colorectal liver metastasis have focused largely on overall survival. We investigated the impact of codon-specific KRAS mutations on the rates and patterns of recurrence in patients after surgery for colorectal liver metastasis (CRLM). METHODS All patients who underwent curative-intent surgery for CRLM between 2002 and 2015 at Johns Hopkins who had available data on KRAS mutation status were identified. Clinico-pathologic data, recurrence patterns, and recurrence-free survival (RFS) were assessed using univariable and multivariable analyses. RESULTS A total of 512 patients underwent resection only (83.2%) or resection plus radiofrequency ablation (16.8%). Although 5-year overall survival was 64.6%, 284 (55.5%) patients recurred with a median RFS time of 18.1 months. The liver was the initial recurrence site for 181 patients, whereas extrahepatic recurrence was observed in 162 patients. Among patients with an extrahepatic recurrence, 102 (63%) had a lung recurrence. Although overall KRAS mutation was not associated with overall RFS (P = 0.186), it was independently associated with a worse extrahepatic (P = 0.004) and lung RFS (P = 0.007). Among patients with known KRAS codon-specific mutations, patients with codon 13 KRAS mutation had a worse 5-year extrahepatic RFS (P = 0.01), whereas codon 12 mutations were not associated with extrahepatic (P = 0.11) or lung-specific recurrence rate (P = 0.24). On multivariable analysis, only codon 13 mutation independently predicted worse overall extrahepatic RFS (P = 0.004) and lung-specific RFS (P = 0.023). CONCLUSIONS Among patients undergoing resection of CRLM, overall KRAS mutation was not associated with RFS. KRAS codon 13 mutations, but not codon 12 mutations, were associated with a higher risk for overall extrahepatic recurrence and lung-specific recurrence. Cancer 2016. © 2016 American Cancer Society.

Abstract
OBJECTIVE To investigate whether liver metastases contribute to metastatic spread of colorectal cancer (CRC) by shedding intact tumor cells. BACKGROUND Metastases represent the primary cause of death in CRC. Understanding the metastatic activity of metastases and which patients are at high risk for tumor cell dissemination may, therefore, have significant influence on cancer care in the future. METHODS Circulating tumor cells (CTCs) were detected in the hepatic inflow (portal venous blood [PVB]) and outflow compartment (hepatic venous blood [HVB]) of a training (n = 55) and validation (n = 50) set using the CellSearch system. Isolated CTC from the HVB were subjected to gene expression analyses by quantitative polymerase chain reaction. RESULTS CTC detection rate (37.2% vs 19.6%; P = 0.04) and count (mean: 12.7, SEM: ± 5.9 vs 1.9; ± 1.2; P = 0.01) were significantly higher in HVB compared to PVB. The increased CTC detection rate (54% vs 11.4%; P < 0.001) and CTC count (14.7 ± 5.1 vs 1.1 ± 0.6; P < 0.001) in the HVB compared to the PVB compartment was confirmed in the validation cohort. Expression of epithelial markers and genes involved in cell-to-cell and cell-to-matrix adhesion was reduced in CTC compared to tumor cells in liver metastases. Metastasis size greater than 5 cm was associated with CTC shedding from established liver metastases in the training and validation cohorts. CONCLUSIONS Colorectal liver metastases shed intact tumor cells with an invasive phenotype. Metastasis size serves as a surrogate marker for metastatic activity of colorectal liver metastases.

Abstract
BACKGROUND Colorectal cancer (CRC) accounts for 9.7% of all cancers with 1.4 million new cases diagnosed each year. 19-31% of CRC patients develop colorectal liver metastases (CRLM), and 23-38% develop extra-hepatic disease (EHD). The aim of this systematic review was to determine overall survival (OS) in patients resected for CRLM and known EHD. METHODS A systematic review was undertaken to identify studies reporting OS after resection for CRLM in the presence of EHD. Proportional meta-analyses and relative risk of death before five years were assessed between patient groups. RESULTS A total of 15,144 patients with CRLM (2308 with EHD) from 52 studies were included. Three and 5-year OS were 58% and 26% for lung, 37% and 17% for peritoneum, and 35% and 15% for lymph nodes, respectively. The combined relative risk of death by five years was 1.49 (95% CI = 1.34-1.66) for lung, 1.59 (95% CI = 1.16-2.17) for peritoneal and 1.70 (95% CI = 1.57-1.84) for lymph node EHD, in favour of resection in the absence of EHD. CONCLUSION This review supports attempts at R0 resection in selected patients and rejects the notion that EHD is an absolute contraindication to resection.

Abstract
BACKGROUND Various clamping procedures are used to decrease bleeding during liver resections but their effect on central venous pressure (CVP) remains unclear. The aim of this study was to assess the variations of the CVP during two different clamping procedures. METHODS We retrospectively reviewed 29 patients (19 males, 10 females) who had Pringle maneuver (PM) and clamping of the inferior vena cava below the liver (IVCC) during major liver resections. RESULTS Mean decrease of the CVP after PM, IVCC, and PM+IVCC was 0.84 ± 1.37, 2.17 ± 2.13 and 3.17 ± 2.56 cmH20, respectively (P=0.02, P<0.0001 and P<0.0001, respectively). IVCC was more effective in inducing a decrease of the CVP than PM alone (P<0.05). The combination of both PM and IVCC induced the greatest decrease but not to a level of significance compared to IVCC alone (P=0.25). CONCLUSION IVCC remains the more efficient procedure to lower the CVP. However, although PM is commonly used to control vascular inflow within the liver its significant influence on the CVP could participate to the reduction of bleeding during liver resections.

Abstract
BACKGROUND Discussions about the benefit of liver resection (LRx) for non-colorectal, non-neuroendocrine metastases are controversial. This study aimed to analyze the outcome of LRx for these patients and validate a previously published prognostic risk model. METHODS The study analyzed 150 patients who underwent LRx for non-colorectal non-neuroendocrine (NCNN) metastases. Patients' demographics, tumor characteristics, treatment options, and postoperative outcome were investigated. The Kaplan-Meier method and Cox regression models were used to assess survival and prognostic variables. RESULTS After a median follow-up period of 61 months, 39 % of the patients were alive. The 30-day mortality rate was 0.7 %. The overall, disease-free, and intrahepatic recurrence-free survival rates were respectively 42, 29, and 51 % at 5 years and 28, 23, and 47 % at 10 years. The negative prognostic factors identified in the multivariate analysis were melanoma (p = 0.04), squamous tumors (p = 0.01), and a primary tumor liver metastasis, with an interval shorter than 2 years (p = 0.02), whereas the predictive prognostic factors identified were breast cancer (p = 0.04), stromal tumors (p = 0.03), and major LRx (p = 0.04). The prognostic risk score stratified patients into low risk (0-3 points: n = 50; 5-year overall survival [OS] 58 %), medium risk (4-6 points: n = 91; 5-year OS 35 %), and high risk (≥7 points: n = 9; 5-year OS, 33 %) groups (p = 0.01). CONCLUSION Liver resection for patients with NCNN metastases is a safe treatment option. More than 25 % of patients can achieve a long-term survival of 10 years when the histology of the primary tumor and the surrogates for the individual biologic tumor behavior are taken into account. Exclusion of patients with NCNN liver metastases from surgical therapy is no longer justified.

Abstract
BACKGROUND In patients with advanced colorectal cancer, KRAS mutation status predicts response to treatment with monoclonal antibody targeting the epithelial growth factor receptor (EGFR). Recent reports have provided evidence that KRAS mutation status has prognostic value in patients with resectable colorectal liver metastases (CLM) irrespective of treatment with chemotherapy or anti-EGFR therapy. A meta-analysis was undertaken to clarify the impact of KRAS mutation on outcomes in patients with resectable CLM. METHODS PubMed, Embase and Cochrane Library databases were searched systematically to identify full-text articles reporting KRAS-stratified overall (OS) or recurrence-free (RFS) survival after resection of CLM. Hazard ratios (HRs) and 95 per cent c.i. from multivariable analyses were pooled in meta-analyses, and a random-effects model was used to calculate weight and overall results. RESULTS The search returned 355 articles, of which 14, including 1809 patients, met the inclusion criteria. Eight studies reported OS after resection of CLM in 1181 patients. The mutation rate was 27.6 per cent, and KRAS mutation was negatively associated with OS (HR 2.24, 95 per cent c.i. 1.76 to 2.85). Seven studies reported RFS after resection of CLM in 906 patients. The mutation rate was 28.0 per cent, and KRAS mutation was negatively associated with RFS (HR 1.89, 1.54 to 2.32). CONCLUSION KRAS mutation status is a prognostic factor in patients undergoing resection of colorectal liver metastases and should be considered in the evaluation of patients having liver resection.
