Retrospective Evaluation of the Prognostic Value of Histological Growth Pattern in Patients with Colorectal Peritoneal Metastases Undergoing Curative-Intent Cytoreductive Surgery. Ann Surg Oncol 2024; 31:3778-3784. [PMID: 38491312 PMCID: PMC11076343 DOI: 10.1245/s10434-024-15125-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Accepted: 02/17/2024] [Indexed: 03/18/2024]
Abstract
BACKGROUND Two distinct histological growth patterns (HGPs) were described in patients with peritoneal metastasis of colorectal cancer origin (PMCRC) with limited Peritoneal Cancer Index (PCI) ≤ 6 who did not receive neoadjuvant chemotherapy (NAC) and were treated with cytoreductive surgery (CRS) ± hyperthermic intraperitoneal chemotherapy (HIPEC): pushing HGP (P-HGP) and infiltrating HGP (I-HGP). Patients with dominant P-HGP (> 50%) had significantly better disease-free survival (DFS) and overall survival (OS). OBJECTIVE We aimed to determine whether these previous observations regarding the prognostic value of HGP in patients with PMCRC with low PCI (≤ 6) are also valid in all operable patients, regardless of whether they received NAC or not and regardless of PCI score. METHODS This was a retrospective study including 76 patients who underwent complete CRS ± HIPEC for PMCRC between July 2012 and March 2019. In each patient, up to five of the largest excised peritoneal nodules were analyzed for their tumor-to-peritoneum interface. Correlations between NAC, HGP, and prognosis were further explored. RESULTS Thirty-seven patients (49%) had dominant P-HGP and 39 (51%) had dominant I-HGP. On univariate analysis, patients with P-HGP ≤ 50% had significantly lower OS than those with dominant P-HGP > 50% (39 versus 60 months; p = 0.014) confirmed on multivariate analysis (hazard ratio 2.4, 95% confidence interval 1.3-4.5; p = 0.006). There were no significant associations between NAC and type of HGP. CONCLUSIONS This study confirms the prognostic value and reproducibility of the two previously reported HGPs in PMCRC. Dominant P-HGP is associated with better DFS and OS in patients undergoing curative-intent CRS ± HIPEC compared with I-HGP, independently of the extent of peritoneal disease burden.

Abstract
BACKGROUND Two-staged hepatectomy (TSH) including portal vein embolization (PVE) may offer surgical treatment for extensive bilobar colorectal liver metastases (CRLM). This study aimed to investigate the feasibility and outcomes of extended right hepatectomy (ERH) within TSH including PVE for patients with extended CRLM. METHODS We retrospectively collected data of patients who underwent TSH for extended CRLM between 2015 and 2021 at our institution. Clearance of the left liver lobe (clear-up, CU) associated with PVE was followed by ERH. RESULTS Minimally invasive (n = 12, 46%, MIH) or open hepatectomy (n = 14, 54%, OH) was performed. Postoperative major morbidity and 90-day mortality were 54% and 0%. Three-year overall survival was 95%. Baseline characteristics, postoperative and long-term outcomes were comparable between MIH and OH. However, hospital stay was significantly shorter after MIH (8 vs. 15 days, p = 0.008). Additionally, the need for intraoperative transfusions tended to be lower in the MIH group (17% vs. 50%, p = 0.110). CONCLUSIONS ERH following CU and PVE for extended CRLM is feasible and safe in laparoscopic and open approaches. MIH for ERH may result in shorter postoperative hospital stays. Further high-volume, multicenter studies are required to evaluate the potential superiority of MIH.

Abstract
PURPOSE The objective of the COLLISION RELAPSE trial is to prove or disprove superiority of neoadjuvant systemic therapy followed by repeat local treatment (either thermal ablation and/or surgical resection), compared to repeat local treatment alone, in patients with at least one recurrent locally treatable CRLM within one year and no extrahepatic disease. METHODS A total of 360 patients will be included in this phase III, multicentre randomized controlled trial. The primary endpoint is overall survival. Secondary endpoints are distant progression-free survival, local tumour progression-free survival analysed per patient and per tumour, systemic therapy-related toxicity, procedural morbidity and mortality, length of hospital stay, pain assessment and quality of life, cost-effectiveness ratio and quality-adjusted life years. DISCUSSION If the addition of neoadjuvant systemic therapy to repeat local treatment of CRLM proves to be superior compared to repeat local treatment alone, this may lead to a prolonged life expectancy and increased disease-free survival at the cost of possible systemic therapy-related side effects. LEVEL OF EVIDENCE Level 1, phase III randomized controlled trial. TRIAL REGISTRATION NCT05861505. May 17, 2023.

Abstract
BACKGROUND Different histological growth patterns (HGP) describing the tumor-to-liver interface have been described in colorectal liver metastases and have been associated with a strong prognostic value. However, HGP of peritoneal metastases (PM) of colorectal cancer (CRC) have not yet been described. Our objective was to determine whether distinct HGP can be identified in PMCRC and to evaluate their potential prognostic value in these patients. METHODS This retrospective study included 38 patients who underwent curative-intent surgery for PMCRC between July 2012 and March 2019, with PCI≤6, and who had not received preoperative chemotherapy. In each patient, the tumor-to-peritoneum interface was evaluated in the excised peritoneal nodules. The association between HGP and postoperative survival was analyzed by using the Kaplan-Meier method. RESULTS Two distinct HGP were identified: a pushing-type (P-HGP), characterized by a fibrous rim separating the PM and peritoneum, and an infiltrating-type (I-HGP), characterized by focal penetration of tumor cells into the surrounding peritoneal lining without a fibrous rim. Fifteen patients had dominant P-HGP, and 23 patients had dominant I-HGP. Patients with dominant P-HGP (>50% tumor-peritoneum interface) had a significantly better DFS (30 months) than those with P-HGP <50% (9 months; p = 0.029). Patients with a P-HGP dominance >60% had better OS (131 months) than those with P-HGP <60% (41 months; p = 0.044). CONCLUSIONS This is the first description of two distinct, reproducible HGP in PMCRC. The dominant P-HGP is associated with a favorable prognosis in patients with PMCRC, compared with I-HGP, suggesting that this parameter could ultimately represent a new prognostic biomarker.

Abstract
Colorectal cancer is one of the most common cancers in the United States and treatment options are limited for patients who develop liver metastases. Several chemotherapeutic regimens have been used for transvascular liver-directed therapy in the treatment of colorectal liver metastases without clear evidence of superiority of one therapy over another. We describe the development of a novel nanoemulsion through combining irinotecan (IRI), a first line systemic agent used for the treatment of colon cancer, with lipiodol, an oily contrast medium derived from poppy seed oil, and evaluated its pharmacokinetic and biodistribution profile as a function of portal venous chemoembolization (PVCE) versus transarterial chemoembolization (TACE) delivery. The Tessari technique was used to create a stable emulsion (20 mg IRI mixed with 2 mL lipiodol) with resultant particle size ranging from 28.9 nm to 56.4 nm. Pharmacokinetic profile established through venous sampling in Buffalo rats demonstrate that the area under the curve (AUC0−∞) of IRI was significantly less after PVCE with IRI-lipiodol as compared to IRI alone (131 vs. 316 µg*min/mL, p-value = .023), suggesting significantly higher amounts of IRI retention in the liver with the IRI-lipiodol nanoemulsion via first-pass extraction. Subseqent biodistribution studies in tumor-bearing WAG/Rjj rats revealed more IRI present in the tumor following TACE versus PVCE (29.19 ± 12.33 µg/g versus 3.42 ± 1.62; p-value = .0033) or IV (29.19 ± 12.33 µg/g versus 1.05 ± 0.47; p-value = .0035). The IRI-lipiodol nanoemulsion demonstrated an acceptable hepatotoxicity profile in all routes of administration. In conclusion, the IRI-lipiodol nanoemulsion via TACE showed promise and warrants further investigation as an option for the treatment of metastatic colorectal cancer.

Abstract
ABSTRACT The aim of this study was to investigate the expression of phosphatase of regenerating live-3 (PRL-3) in human stage III colorectal cancer (CRC) and to evaluate its correlation with metachronous liver metastasis (MLM) and prognosis.The retrospective cohort study included 116 stage III CRC primary tumors and 60 normal colorectal tissues. PRL-3 expression was measured by immunohistochemistry. We investigated the correlation of PRL-3 with clinicopathologic features by the chi-square test. The association of PRL-3 expression with MLM was assessed by binary logistic regression. Overall survival (OS) and disease-free survival (DFS) between patients with positive PRL-3 expression and those with negative PRL-3 expression were compared by the Kaplan-Meier method and Cox proportional hazards regression model.We found that 32.8% of stage III CRC primary tumors were PRL-3 positive, and 15.0% of normal colorectal epithelia showed high PRL-3 expression (P = .012). Seventeen tumors (47.2%) among 36 cases that developed MLM were PRL-3 positive, and only 21 tumors (26.3%) in the 80 cases that did not develop MLM had positive PRL-3 expression (P = .026). PRL-3 expression was associated with MLM (P = .028). Patients with positive expression of PRL-3 showed a significantly shorter OS (40.32 ± 3.97 vs 53.96 ± 2.77 months, P = .009) and DFS (34.97 ± 4.30 vs 44.48 ± 2.89 months, P = .036). A multivariate analysis indicated that PRL-3 expression was an independent unfavorable prognostic factor for OS (P = .007).Our study suggested that high PRL-3 expression is an independent risk factor for MLM and poor prognosis. PRL-3 is expected to be a promising biomarker for predicting the incidence of MLM and prognosis in patients with stage III CRC.

Abstract
BACKGROUND Two-stage hepatectomy (TSH) is an important tool in the management of bilateral colorectal liver metastases (CRLM). This study sought to examine the presentation, management, and outcomes of patients completing TSH in major hepatobiliary centers in the United States (US). METHODS A retrospective review from five liver centers in the US identified patients who completed a TSH procedure for bilateral CRLM. RESULTS From December 2000 to March 2016, a total of 196 patients were identified. The majority of procedures were performed using an open technique (n = 194, 99.5%). The median number of tumors was 7 (range 2-33). One-hundred and twenty-eight (65.3%) patients underwent portal vein embolization. More patients received chemotherapy prior to the first stage than chemotherapy administration preceding the second stage (92% vs. 60%, p = 0.308). Median overall survival (OS) was 50 months, with a median follow-up of 28 months (range 2-143). Hepatic artery infusion chemotherapy was administered to 64 (32.7%) patients with similar OS as those managed without an infusion pump (p = 0.848). Postoperative morbidity following the second-stage resection was 47.4%. Chemotherapy prior to the second stage did not demonstrate an increased complication rate (p = 0.202). Readmission following the second stage was 10.3% and was associated with a decrease in disease-free survival (p = 0.003). OS was significantly decreased by positive resection margins and increased estimated blood loss (EBL; p = 0.036 and p = 0.05, respectively). CONCLUSION This is the largest TSH series in the US and demonstrates evidence of safety and feasibility in the management of bilateral CRLM. Outcomes are influenced by margin status and operative EBL.

Abstract
Patients with colorectal cancer (CRC) have benefited significantly from advances in multimodal treatment with significant improvements in long-term survival. More patients are currently being treated with surgical resection or ablation following neoadjuvant or adjuvant chemotherapy. However, several cytotoxic agents that are administered routinely have been linked to liver toxicities that impair liver function and regeneration. Recognition of chemotherapy-related liver toxicity emphasizes the importance of multidisciplinary planning to optimize care. This review aims to summarize current data on multimodal treatment concepts for CRC, provide an overview of liver damage caused by commonly administered chemotherapeutic agents, and evaluate currently suggested protective agents.

Abstract
PURPOSE Prognostic schemes that rely on clinical variables to predict outcome after resection of colorectal metastases remain imperfect. We hypothesized that molecular markers can improve the accuracy of prognostic schemes. METHODS We screened the transcriptome of matched colorectal liver metastases (CRCLM) and primary tumors from 42 patients with unresected CRCLM to identify differentially expressed genes. Among the differentially expressed genes identified, we looked for associations between expression and time to disease progression or overall survival. To validate such associations, mRNA levels of the candidate genes were assayed by qRT-PCR from CRCLM in 56 additional patients who underwent hepatectomy. RESULTS Seven candidate genes were selected for validation based on their differential expression between metastases and primary tumors and a correlation between expression and surgical outcome: lumican; tissue inhibitor metalloproteinase 1; basic helix-loop-helix domain containing class B2; fibronectin; transmembrane 4 superfamily member 1; mitogen inducible gene 6 (MIG-6); and serpine 2. In the hepatectomy group, only MIG-6 expression was predictive of poor survival after hepatectomy. Quantitative PCR of MIG-6 mRNA was performed on 25 additional hepatectomy patients to determine if MIG-6 expression could substratify patients beyond the clinical risk score. Patients within defined clinical risk score categories were effectively substratified into distinct groups by relative MIG-6 expression. CONCLUSIONS MIG-6 expression is inversely associated with survival after hepatectomy and may be used to improve traditional prognostic schemes that rely on clinicopathologic data such as the Clinical Risk Score.

Abstract
Significant incidental findings reported on computed tomography (CT) scans are common. This article describes a 72-year-old man evaluated for possible bowel obstruction in whom was found a 3.1-cm x 2.6-cm centrally located enhancing mass in the left kidney highly suspicious for renal cell carcinoma. Due to substantial medical comorbidities, the patient was deemed a poor surgical candidate for either partial or complete nephrectomy. Interventional radiology was consulted for a minimally invasive ablation procedure. The large size and central location of the tumor involving the renal collecting system initially precluded definitive percutaneous cryoablation. Intra-arterial embolization was used as neoadjuvant therapy to decrease tumor burden. Fluoroscopy-guided bland embolization was performed targeting the arterial supply of the mass until stagnation of flow was achieved. A subsequent two-month post-embolization follow-up CT scan showed a 30% reduction in tumor size. Shrinkage of the mass from a central to a more peripheral location allowed for a cryoablation approach that would avoid damage to the vulnerable collecting system. Cryoablation was performed, and intraoperative CT demonstrated complete coverage of the tumor by the ice ball with no damage to the renal collecting system. A follow-up CT scan four years later showed no residual malignancy at the ablation site.

Abstract
BACKGROUND Fluoro-L-thymidine (FLT) is a positron emission tomography/computed tomography (PET/CT) tracer which reflects proliferative activity in a cancer lesion. The main objective of this prospective explorative study was to evaluate whether FLT-PET can be used for the early evaluation of treatment response in colorectal cancer patients (CRC) with liver metastases. Patients with metastatic CRC having at least one measurable (>1 cm) liver metastasis receiving first-line chemotherapy were included. A FLT-PET/CT scan was performed at baseline and after the first treatment. The maximum and mean standardised uptake values (SUVmax, SUVmean) were measured. After three cycles of chemotherapy, treatment response was assessed by CT scan based on RECIST 1.1. RESULTS Thirty-nine consecutive patients were included of which 27 were evaluable. Dropout was mainly due to disease complications. Nineteen patients (70%) had a partial response, seven (26%) had stable disease and one (4%) had progressive disease. A total of 23 patients (85%) had a decrease in FLT uptake following the first treatment. The patient with progressive disease had the highest increase in FLT uptake in SUVmax. There was no correlation between the response according to RECIST and the early changes in FLT uptake measured as SUVmax (p = 0.24). CONCLUSIONS No correlation was found between early changes in FLT uptake after the first cycle of treatment and the response evaluated from subsequent CT scans. It seems unlikely that FLT-PET can be used on its own for the early response evaluation of metastatic CRC.

Prospective comparison of gadoxetic acid-enhanced liver MRI and contrast-enhanced CT with histopathological correlation for preoperative detection of colorectal liver metastases following chemotherapy and potential impact on surgical plan. HPB (Oxford) 2017; 19:992-1000. [PMID: 28760631 DOI: 10.1016/j.hpb.2017.06.014] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2017] [Revised: 04/20/2017] [Accepted: 06/28/2017] [Indexed: 12/12/2022]
Abstract
OBJECTIVE To prospectively compare the diagnostic performance of gadoxetic acid-enhanced MRI (EOB-MRI) and contrast-enhanced CT (CECT) for preoperative detection of colorectal liver metastases (CRLM) following chemotherapy and to evaluate the potential change in the hepatic resection plan. METHODS 51 patients with CRLM treated with preoperative chemotherapy underwent liver imaging by EOB-MRI and CECT prospectively. Two independent blinded readers characterized hepatic lesions on each imaging modality using a 5-point scoring system. 41 patients underwent hepatic resection and histopathological evaluation. RESULTS 151 CRLM were confirmed by histology. EOB-MRI, compared to CECT, had significantly higher sensitivity in detection of CRLM ≤1.0 cm (86% vs. 45.5%; p < 0.001), significantly lower indeterminate lesions diagnosis (7% vs. 33%; p < 0.001) and significantly higher interobserver concordance rate in characterizing the lesions ≤1.0 cm (72% vs. 51%; p = 0.041). The higher yield of EOB-MRI could have changed the surgical plan in 45% of patients. CONCLUSION Following preoperative chemotherapy, EOB-MRI is superior to CECT in detection of small CRLM (≤1 cm) with significantly higher sensitivity and diagnostic confidence and interobserver concordance in lesion characterization. This improved diagnostic performance can alter the surgical plan in almost half of patients scheduled for liver resection.

Abstract
BACKGROUND The importance of preoperative chemotherapy in a multimodality management of patients with colorectal liver metastases (CRLM) has been demonstrated. We analyse the carcinoembryonic antigen (CEA) changes following neoadjuvant chemotherapy in patients with CRLM who underwent liver resection. METHODS The final cohort included 107 eligible patients. Increased CEA levels following neoadjuvant chemotherapy were defined as the increase of baseline CEA level at diagnosis of CRLM compared with the CEA level after completion of neoadjuvant chemotherapy. Disease-free survival (DFS), post-recurrence survival (PRS) and overall survival (OS) were calculated using both Kaplan-Meier and multivariate Cox-regression methods. RESULTS CEA increase was associated with decreased PRS and OS (HR 2.69; 95 % CI, 1.28-5.63; p = 0.009, and HR 2.50; 95 % CI, 1.12-5.56; p = 0.025, respectively) in multivariate analysis, but there was no association between CEA changes and DFS. CEA increase was only associated with disease progression during preoperative chemotherapy (p = 0.014). Interestingly, this association was not absolute, as only 5 of the 11 patients with disease progression demonstrated CEA increase. Regarding the remaining 12 patients with CEA increase, according to RECIST criteria, eight patients demonstrated partial response and four patients stable disease. CONCLUSION In this study, we demonstrated the CEA increase following neoadjuvant chemotherapy as an adverse prognostic factor for PRS, and OS but not for DFS in patients undergoing liver resection for liver-only colorectal metastases.

Abstract
BACKGROUND Total liver volume (TLV) empirically changes after aggressive preoperative chemotherapy for colorectal liver metastases (CLM). However, the actual degree of changes in normal liver parenchyma and its clinical relevance remain unclear. METHODS Morphometric data of 110 patients who underwent initial hepatectomy after preoperative chemotherapy were reviewed. TLVs before and after chemotherapy were measured using a computer-based volumetry software and their relevance to clinical factors was investigated. RESULTS More than 10% of decrease in TLV was observed in 42 (38.2%) patients, and more than 10% of increase was observed in 11 (10.0%) patients. Change in TLV was within 10% in the remaining 57 (51.8%) patients. Indocyanine green retention rate at 15 min (ICG-R15) value was significantly higher in patients with TLV decrease more than 10% (13.4 vs. 9.3 vs. 8.5%; p = 0.004). Steatosis in the underlying liver was significantly frequent in patients with TLV increase more than 10% (p < 0.001). Multivariate logistic regression analysis revealed that more than 10% of shrinkage in TLV after chemotherapy was independently associated with ICG-R15 >15% (odds ratio 8.8; p = 0.0001). Tendency of correlation was confirmed in the kinetic changes in TLV and ICG-R15 during chemotherapy even though there was no statistical significance (r = -0.33, p = 0.080). CONCLUSION Perichemotherapy kinetic changes in TLV may predict histopathologic changes or changes in hepatic functional reserve in the underlying liver. More than 10% of shrinkage in TLV is associated with impaired hepatic functional reserve, and it can be a new supplemental finding in the prediction of surgical risk of major hepatectomy for CLM.

Abstract
Peri-operative chemotherapy has been proposed to improve the survival of patients with colorectal cancer hepatic metastases (CRCHM). However, the role of the adjuvant chemotherapy post-metastasectomy for CRCHM patients who have undergone pre-operative chemotherapy is still undetermined. We retrospectively analyzed the role of adjuvant chemotherapy post-metastasectomy on relapse-free survival (RFS) and overall survival (OS) in 163 CRCHM patients who received pre-operative chemotherapy using a Kaplan-Meier curve and univariate/multiple Cox model. Ten patients with rapidly progressing disease were further excluded in a sensitivity analysis. Seven risk factors (metachronous/synchronous metastases, differentiated grade of the primary tumor, number of metastases, size of the max metastasis, duration of pre-operative chemotherapy, radiologic response and pathologic regression) were used to stratify patients and investigate the beneficial features of adjuvant chemotherapy post-metastasectomy. The results indicated that adjuvant chemotherapy post-metastasectomy prolonged both RFS (median RFS: 3.3 vs. 10.2 m, P = 0.002) and OS (median OS: 28.1 vs. 40.7 m, P = 0.005) in CRCHM patients who received pre-operative chemotherapy. After adjusting for other risk factors in a multiple Cox model, the adjuvant chemotherapy group was estimated to have a 54.0 % relapse-free survival (hazard ratio (HR) = 0.46, 95 % confidence interval (CI) 0.31 - 0.69, P < 0.001) and a 55.0 % overall survival (HR [95 % CI]: 0.45 [0.26 - 0.78], P = 0.005) advantage compared to patients without adjuvant chemotherapy. Additionally, the benefit of adjuvant chemotherapy post-liver resection remained in sensitivity analysis. After the risk stratification, patients with synchronous metastases, poor differentiation, ≥ 3 metastases per patient, size of the maximum metastasis >3 cm, a short duration of pre-operative chemotherapy, radiologic response and poor pathologic regression seem to benefit more from adjuvant chemotherapy. To sum up, adjuvant chemotherapy post-metastasectomy might be considered for CRCHM patients who have received preoperative chemotherapy, especially for those with high-risk factors.

Abstract
PURPOSE The purpose of the study was to correlate the apparent diffusion coefficient (ADC) values of diffusion-weighted MR imaging (DW-MRI) by 3T device with the histological tumour regression grading (TRG) analysis of colorectal liver metastases after preoperative chemotherapy. MATERIALS AND METHODS Our study included thirty-five patients with colorectal liver metastases who had undergone MRI by 3T device (GE DISCOVERY MR750; GE Healthcare) after preoperative chemotherapy. DW-MRI was performed using a single-shot spin-echo echo-planar sequence with multiple b-values (0, 150, 500, 1000, 1500s/mm2), thus obtaining an ADC map. For each liver lesion (more than 1cm in diameter) the fitted ADC values were calculated by two radiologists in conference and three ROIs were drawn: around the entire tumour (ADCe), at the tumour periphery (ADCp) and at the tumour center (ADCc). All ADC values were correlated with histopathological findings after surgery. Hepatic metastases were pathologically classified into five groups on the basis of TRG. Statistical analysis was performed on a per-lesion basis utilizing the one-way analysis of variance (ANOVA). This retrospective study was approved by our institutional review board; written informed consent was obtained from all patients. RESULTS A total of 106 colorectal liver metastases were included for image analysis. TRG1, TRG2, TRG3, TRG4 and TRG5 were observed in 4, 14, 36, 35 and 17 lesions, respectively. ADCe and ADCp values were significantly higher in lesions classified as TRG1 (2.40±0.12×10-9m2/s and 2.28±0.26×10-9m2/s, respectively) and as TRG2 (1.40±0.31×10-9m2/s and 1.44±0.35×10-9m2/s), compared to TRG3 (1.16±0.13×10-9m2/s and 1.01±0.18×10-9m2/s), TRG4 (1.10±0.26×10-9m2/s and 0.97±0.24×10-9m2/s), and TRG5 (0.93±0.17×10-9m2/s and 0.82±0.28×10-9m2/s). ADCe, ADCp and ADCc values were significantly different in TRG classes (p<0.0001). Statistical correlations were found between the ADCe, ADCp, ADCc values and the TRG classes (Spearman correlation coefficient were -0.568, -0.542 and -0.554, respectively). CONCLUSION Our study showed a significant correlation between ADC values of 3T DW-MRI and histological TRG of colorectal liver metastases after preoperative chemotherapy.

Abstract
OBJECTIVES To evaluate the safety and efficiency of the conversion therapy: chemotherapy plus anti-epidermal growth factor Receptor (EGFR) or anti-vascular endothelial growth factor receptor (VEGFR) monoclonal antibodies (MoAbs) with different rat sarcoma (RAS) status in patients with potentially resectable colorectal liver metastases (CRLM). METHODS Randomized controlled trials (RCTs) were identified and the association between RAS mutation and clinical outcome in CRLM patients treated with anti-EGFR or anti-VEGFR MoAbs was investigated. Searches were performed for data recorded between January 2005 and August 2015 in the Cochrane Library, MEDLINE, PubMed, and EMBASE. Objective response rates (ORR), conversion resection rates (CRR), R0 resection rates (R0R) and rate ratios (RR) were used to assess the strength of the association between different RAS status, MoAbs and conversion efficiency. RESULTS In the conversion therapy, ORR and RR were associated with patients with wild type RAS and different MoAbs. Patients treated with MoAbs: anti-VEGFR or anti-EGFR drugs, resulted in higher ORR, (RR=1.53, 95% confidence interval [CI]: 1.27-1.84, P < 0.05). Furthermore, anti-EGFR regimens displayed higher ORR compared with anti-VEGFR regimens in CRLM patients, (RR=1.15, 95%CI: 1.04-1.26, P < 0.05). However, CRLM patients with mutant type RAS did not benefit from anti-EGFR therapy, (RR=0.91, 95%CI: 0.76-1.08, P<0.05) and wild type RAS patients displayed higher ORR with anti-EGFR therapy, (RR=1.56, 95%CI: 1.16-2.01, P <0.05). In addition, the patients achieved higher resection rates (RR=1.67, 95%CI: 1.00-2.81, P ≤ 0.05) and R0 resection (RR=1.85, 95%CI: 1.04-3.27, P < 0.05). CONCLUSION We noted that the addition of MoAbs (anti-EGFR or anti-VEGFR) to standard chemotherapy could improve conversion efficiency for patients with potentially resectable CRLM patients, and anti-EGFR therapies maybe more effective than anti-VEGFR therapies. RAS status is a potential predictive marker of the clinical benefit resulting from treatment with anti-EGFR MoAbs therapy in CRLM patients and anti-EGFR MoAbs therapy could displayed greater efficiency only in patients with wild type RAS.

Abstract
Currently, partial hepatectomy is the treatment of choice for a wide variety of liver and biliary conditions. Among the possible complications of partial hepatectomy, acute kidney injury (AKI) should be considered as an important cause of increased morbidity and postoperative mortality. Difficulties in the data analysis related to postoperative AKI after liver resections are mainly due to the multiplicity of factors to be considered in the surgical patients, moreover, there is no consensus of the exact definition of AKI after liver resection in the literature, which hampers comparison and analysis of the scarce data published on the subject. Despite this multiplicity of risk factors for postoperative AKI after partial hepatectomy, there are main factors that clearly contribute to its occurrence. First factor relates to large blood losses with renal hypoperfusion during the operation, second factor relates to the occurrence of post-hepatectomy liver failure with consequent distributive circulatory changes and hepatorenal syndrome. Eventually, patients can have more than one factor contributing to post-operative AKI, and frequently these combinations of acute insults can be aggravated by sepsis or exposure to nephrotoxic drugs.

Abstract
PURPOSE The aim of this study was to assess splenic volume and to correlate unidimensional measurements with reference volumetric changes in chemotherapy-treated patients with colorectal cancer (CRC) liver metastases. METHODS Forty consecutive patients were selected from the cohort of a previously reported study of chemotherapy-related morbidity following major hepatectomy for CRC liver metastases. Patients were treated for 6 months prior to resection, with imaging performed at baseline and after 6 months of chemotherapy. Three unidimensional spleen measurements were recorded-width, thickness, and height (W, T, and H). Reference splenic volume was measured at baseline and after chemotherapy. The best unidimensional splenic measurement was determined by regression analysis. The 95% CI for the predicted values and R (2) values was calculated for each regression. The percentage of volume increase at 6 months was calculated. RESULTS W and H showed the highest correlation with splenic volume prior to and following chemotherapy (R (2) = 0.65-0.74, p < 0.001), while T showed a low correlation (R (2) = 0.11 and 0.18, p < 0.05). The mean reference splenic volume increased after 6 months of chemotherapy compared to baseline (326 vs. 278 mL). Splenic volume changes showed the highest correlation with changes in W (R (2) = 0.56, p < 0.001), then H (R (2) = 0.40, p < 0.001), but were not significantly correlated with changes in T (R (2) = 0.01, p = 0.055). CONCLUSIONS Our results show the potential utility of measuring changes in splenic width to predict clinically significant changes in splenic volume in chemotherapy-treated patients with CRC liver metastases.

Abstract
We evaluated whether age- and gender-based colorectal cancer screening is cost-effective.Recent studies in the United States identified age and gender as 2 important variables predicting advanced proximal neoplasia, and that women aged <60 to 70 years were more suited for sigmoidoscopy screening due to their low risk of proximal neoplasia. Yet, quantitative assessment of the incremental benefits, risks, and cost remains to be performed.Primary care screening practice (2008-2015).A Markov modeling was constructed using data from a screening cohort. The following strategies were compared according to the Incremental Cost Effectiveness Ratio (ICER) for 1 life-year saved: flexible sigmoidoscopy (FS) 5 yearly; colonoscopy 10 yearly; FS for each woman at 50- and 55-year old followed by colonoscopy at 60- and 70-year old; FS for each woman at 50-, 55-, 60-, and 65-year old followed by colonoscopy at 70-year old; FS for each woman at 50-, 55-, 60-, 65-, and 70-year old. All male subjects received colonoscopy at 50-, 60-, and 70-year old under strategies 3 to 5.From a hypothetical population of 100,000 asymptomatic subjects, strategy 2 could save the largest number of life-years (4226 vs 2268 to 3841 by other strategies). When compared with no screening, strategy 5 had the lowest ICER (US$42,515), followed by strategy 3 (US$43,517), strategy 2 (US$43,739), strategy 4 (US$47,710), and strategy 1 (US$56,510). Strategy 2 leads to the highest number of bleeding and perforations, and required a prohibitive number of colonoscopy procedures. Strategy 5 remains the most cost-effective when assessed with a wide range of deterministic sensitivity analyses around the base case.From the cost effectiveness analysis, FS for women and colonoscopy for men represent an economically favorable screening strategy. These findings could inform physicians and policy-makers in triaging eligible subjects for risk-based screening, especially in countries with limited colonoscopic resources. Future research should study the acceptability, feasibility, and feasibility of this risk-based strategy in different populations.

Abstract
PURPOSE To evaluate the diagnostic performance of diffusion-weighted imaging (DWI) and gadoxetic acid-enhanced magnetic resonance imaging (MRI) to differentiate colorectal liver metastasis (CRLM) with complete pathologic response from those with incomplete response in patients treated with preoperative chemotherapy. METHODS Gadoxetic acid-enhanced liver MRI and DWI were performed after completion of preoperative chemotherapy in patients with CRLM scheduled for liver resection. Metastases were classified as those with complete pathologic response (CR-CRLM) or incomplete response (IR-CRLM) according to postsurgical histopathology. Quantitative analysis was performed on non-contrast-enhanced images and hepatobiliary phase images following gadoxetic acid administration. Apparent diffusion coefficient values (ADC), normalized relative enhancement (NRE), and relative signal intensity difference (RSID) along with their diagnostic measures for detection of CR-CRLM were calculated for all lesions. RESULTS In 23 patients, 10 CR-CRLM and 35 IR-CRLM (mean diameter, 21.2 mm) were evaluated. In CR-CRLM, ADC was significantly higher after exclusion of the outliers (p = 0.030); and RSID was significantly lower (p = 0.008). Combined indices range of ADC = 1.25-1.9 × 10(-3) mm(2)/s, NRE = 0-35% and RSID <120 had 60% sensitivity and 100% specificity for detection of CR-CRLM. CONCLUSION DWI and gadoxetic acid-enhanced MRI appear promising for the detection of CRLM with complete response to preoperative chemotherapy. This could have significant implications for liver resection planning after preoperative chemotherapy.

Abstract
Colorectal cancer (CRC) is the third most common carcinoma worldwide and despite advances in treatment, survival for patients with metastatic disease remains poor. With nearly 50% of patients developing metastases, in vivo investigation is essential to improve outcomes for these patients and numerous murine models of CRC have been developed to allow the study of chemoprevention and chemotherapy, in addition to improving our understanding of the pathogenesis of CRC. Selecting the most appropriate murine model for a specific application will maximize the conversion of potential therapies from the laboratory to clinical practice and requires an understanding of the various models available. This review will provide an overview of the murine models currently used in CRC research, discussing the limitations and merits of each and their most relevant application. It is aimed at the developing researcher, acting as a guide to prompt further reading in planning a specific study.

Abstract
In liver cancer tumor-infiltrating regulatory T cells (Ti-Treg) are potent suppressors of tumor-specific T-cell responses and express high levels of the Treg-associated molecules cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) and glucocorticoid-induced tumor necrosis factor receptor (GITR). In this study, we have evaluated the capacity of GITR-ligation, CTLA-4-blockade and a combination of both treatments to alleviate immunosuppression mediated by Ti-Treg. Using ex vivo isolated cells from individuals with hepatocellular carcinoma (HCC) or liver metastases from colorectal cancer (LM-CRC) we show that treatment with a soluble form of the natural ligand of GITR (GITRL), or with blocking antibodies to CTLA-4, reduces the suppression mediated by human liver tumor-infiltrating CD4+Foxp3+ Treg, thereby restoring proliferation and cytokine production by effector T cells. Importantly, combined treatment with low doses of both molecules exhibited stronger recovery of T cell function compared with either treatment alone. Our data suggest that in patients with primary and secondary liver cancer both GITR-ligation and anti-CTLA-4 mAb can improve the antitumor immunity by abrogating Ti-Treg mediated suppression.

Abstract
Colorectal cancer is a common malignancy and often presents with synchronous or metachronous distant spread. For patients with hepatic metastases, resection is the principal curative option. Liberalization of the indications for hepatic resection has introduced a number of challenges related to the size, distribution, and number of metastases as well as the condition of the future liver remnant. Advances in systemic therapy have solidified its role as both an important adjunct to surgery and also for many patients as a mechanism to facilitate resection. In patients whose disease is marginally resectable as a consequence of the distribution of hepatic lesions that precludes complete resection or out of concern for the future liver remnant, a number of strategies have been advocated, including prehepatectomy systemic therapy, staged surgical approaches, ablative technologies, and preoperative portal vein embolization. It is the purpose of this review to discuss ways in which to optimize the treatment of patients with potentially resectable disease, specifically those who are judged to have "borderline" resectable situations.

Abstract
Despite improved therapy of advanced colorectal cancer, the median overall survival (OS) is still low. A surgical removal has significantly improved survival, if lesions are entirely removed. The purpose of this retrospective explorative study was to evaluate the prognostic value of histological growth patterns (GP) in chemonaive and patients receiving neo-adjuvant therapy. Two-hundred-fifty-four patients who underwent liver resection of colorectal liver metastases between 2007 and 2011 were included in the study. Clinicopathological data and information on neo-adjuvant treatment were retrieved from patient and pathology records. Histological GP were evaluated and related to recurrence free and OS. Kaplan-Meier curves, log-rank test and Cox regression analysis were used. The 5-year OS was 41.8% (95% CI 33.8-49.8%). Growth pattern evaluation of the largest liver metastasis was possible in 224 cases, with the following distribution: desmoplastic 63 patients (28.1%); pushing 77 patients (34.4%); replacement 28 patients (12.5%); mixed 56 patients (25.0%). The Kaplan-Meier analyses demonstrated that patients resected for liver metastases with desmoplastic growth pattern had a longer recurrence free survival (RFS) than patients resected for non-desmoplastic liver metastases (p=0.05). When patients were stratified according to neo-adjuvant treatment in the multivariate Cox regression model, hazard ratios for RFS compared to desmoplastic were: pushing (HR=1.37, 95% CI 0.93-2.02, p=0.116), replacement (HR=2.16, 95% CI 1.29-3.62, p=0.003) and mixed (HR=1.70, 95% CI 1.12-2.59, p=0.013). This was true for chemonaive patients as well as for patients who received neo-adjuvant treatment.

Abstract
PURPOSE The aim of this study was to estimate the effectiveness of surgery in liver metastasis from colorectal cancer. METHODS We conducted a prospective and observational study of patients with colorectal liver metastasis operated on at the San Cecilio University Hospital of Granada from March 2003 until June 2013. The primary variables of the result were survival and morbidity before 30 days of the post-operative period. We also measured preoperative and surgical variables. RESULTS A total of 147 patients with liver metastasis of colorectal origin underwent surgical removal during the period of study, 38 of whom had repeat surgery. 34 had a second resection, 3 had a third one and one only patient had a fourth one, for a total of 185 registered operations. The global 5-year survival rate was 38 and 17 % after 10 years. There were 115 patients who had neither radiofrequency nor exploratory laparotomy, 38 % of them survived over 60 months. The average disease-free time was 23.6 months ± 47.3, with significant differences observed between types of procedures. Patients that were operated on just once (n = 25) had a five-year actuarial survival rate of 35 %, a morbidity rate of 24 % and a mortality rate of 0.6 % (1 patient only). The average hospital stay was 13.8 days and the disease-free time was 15.8 months. CONCLUSION The results obtained in our surgical unit in terms of morbidity, mortality and five-year actuarial survival rates are comparable to those of other units at large institutions, which are currently considered the standards of quality.

Abstract
Increased expression of excision repair cross-complementing 1 (ERCC1) in mCRC patients could be related to their response to Oxaliplatin based chemotherapy. We evaluated ERCC1 mRNA expression levels in primary bowel and liver metastases of 51 patients, and correlated with pathologic parameters and clinical outcomes. A significant negative correlation was detected between primary tumor ERCC1 and both the extent of clear surgical margins (P = 0.0011) and the percent of liver metastasis necrosis (P = 0.0167). No relationship was observed between ERCC1 expression and survival. Further study is needed to assess the promising role of ERCC1 expression as a predictive marker benefiting subgroups for Oxaliplatin.

Abstract
Bevacizumab is a humanized monoclonal antibody targeting vascular endothelial growth factor (VEGF), often used in combinational chemotherapy regimens for the treatment of patients with colorectal liver metastases. However adverse events have been attributed to the use of bevacizumab including gastrointestinal perforations, thrombotic events, hypertension, bleeding, and wound healing complications. 53-year-old male, with a history of colorectal cancer with liver metastasis, receiving a combination of cytotoxic chemotherapy (FOLFIRI, irinotecan with fluorouracil and folinic acid) with bevacizumab presented as an emergency with an incarcerated incisional hernia. The last administration of chemotherapy and bevacizumab had taken place 2 weeks prior to this presentation. As the risk of strangulation of the bowel was increased, a decision was made to take the patient to theatre, although the hazard with respect to wound healing, haemorrhage, and infection risk was high due to the recent administration of chemotherapy with bevacizumab. The patient underwent an open repair of the incarcerated recurrent incisional hernia with placement of a biological mesh, and the postoperative recovery was uncomplicated with no wound healing or bleeding problems.

Abstract
AIM Patients with colorectal liver metastases (CRLM) benefit from liver resection. Bevacizumab is commonly used in these patients resulting in a greater number of patients receiving an operation for a potentially curative liver resection, with initially unresectable liver metastases. Our purpose was to evaluate the effect of preoperative bevacizumab administration on perioperative complications in patients undergoing hepatic resection for CRLM. METHODS A retrospective analysis of patients undergoing hepatic resection for CRLM who received only neoadjuvant chemotherapy (chemotherapy group, n = 133), or neoadjuvant chemotherapy and bevacizumab (chemotherapy and bevacizumab group, n = 103). We compared surgical characteristics, perioperative complications and postoperative liver function. RESULTS The type of liver resection (minor vs major liver resection) was comparable in the two groups (major liver resection 52.6 vs 62.1%, p = 0.144). The addition of bevacizumab to preoperative chemotherapy does not affect the frequency (chemotherapy group vs chemotherapy and bevacizumab group, 35.3 vs 38.8%, p = 0.581), severity (major complications, 20.3 vs 19.4%, p = 0.487) and type of perioperative complications. Preoperative administration of bevacizumab was associated with a higher peak of postoperative alanine aminotransferase levels but did not affect functional recovery of the liver. CONCLUSION Neoadjuvant administration of bevacizumab was not associated with an increased risk of postoperative complications after hepatic resection and did not affect the liver's functional recovery. Patients receiving more than eight cycles of bevacizumab are at an increased risk to develop perioperative complications.

Abstract
The present study aimed to assess the feasibility, safety and efficiency of ultrasound-guided percutaneous microwave ablation (MWA) on liver metastases from colon or rectal cancer. Patients who received MWA therapy for liver metastases from colon or rectal cancer between June 2009 and May 2012 were enrolled in the study. Follow-up data was collected from the patients in order to statistically analyze the adverse effects, concurrent disease and survival status. Of the total 115 patients, 62 presented with colon cancer and 53 with rectal cancer. A total of 78 patients were male and 37 were female. The patient age ranged between 30 and 86 years [mean ± standard deviation (SD), 59.46±11.79 years]. The number of overall ablation lesions was 165, and the diameter of the lesions ranged between 1.3 and 5.0 cm (mean ± SD, 3.10±1.05 cm). Subsequent to treatment, the mean (± SD) hospitalization time was 4.69±2.08 days (range, 2-10 days). The median follow-up time was 28 months (range, 12-48 months) and 5 patients were lost to follow-up. The pain grade was recorded between the 4th and 6th degree following treatment in 23 patients. The body temperatures of 35 patients reached >38°C, with the longest time at this temperature recorded as 5 days. Following treatment, 5 patients presented with pleural effusion and required thoracocentesis and drainage. Following ablation, the rate of local progression was 11.82%. The recurrence rates were 27.8, 48.4 and 59.3% and the cumulative survival rates were 98.1, 87.1 and 78.7% in years 1, 2 and 3 post-treatment, respectively. A total of 14 patients succumbed. No significant differences were observed in the liver metastases of colorectal cancer with regard to gender, age, number of lesions, lesion size and pathological differentiation (P>0.05). Also, no significant difference was observed in the recurrence or cumulative survival rates for years 1, 2 and 3 years post-treatment (P>0.05). In conclusion, ultrasound-guided percutaneous MWA is a safe and competent way to treat inoperable colorectal liver metastases.

Abstract
Colorectal cancer (CRC) incidence has increased during the past decades in Spain, being the first malignant tumour in incidence. Observed mortality for CRC is mainly due to liver and lung metastases. The only curative treatment is surgery; new surgical techniques and neoadjuvant treatments have increased the number of surgery candidate patients. Patients should be managed with a multidisciplinary approach that includes imaging techniques, chemotherapy, surgery and pathological assessment. As an answer to this approach, a group of pathology experts interested on CRC liver metastases aimed to review the diagnosis and prognosis of liver mestastases and developed practical recommendations for its assessment. The expert group revised the current literature and prepared questions to be discussed based on available evidence and on their clinical practise. As a result, recommendations for the assessment of tumour regression of liver metastases are proposed, which could be implemented in oncology centres allowing assessment standardisation for these patients. Prospective multi-center studies to evaluate these recommendations validity will further contribute to improve the standard care of CRC liver metastases patients.

Abstract
The aims of the study were to evaluate therapeutic efficacy and to determine the prognostic factors for treatment success in patients with liver metastases from colorectal cancer (CRC) treated with transarterial chemoembolization (TACE). A total of 564 patients (mean age, 60.3 years) with liver metastases of CRC were repeatedly treated with TACE. In total, 3,384 TACE procedures were performed (mean, six sessions per patient). The local chemotherapy protocol consisted of mitomycin C alone (43.1%), mitomycin C with gemcitabine (27.1%), mitomycin C with irinotecan (15.6%) or mitomycin C with irinotecan and cisplatin (15.6%). Embolization was performed with lipiodol and starch microspheres. Tumor response was evaluated using magnetic resonance imaging or computed tomography. The change in tumor size was calculated and the response was evaluated according to the RECIST-Criteria. Survival rates were calculated according to the Kaplan-Meier method. Prognostic factors for patient's survival were evaluated using log-rank test. Evaluation of local tumor control showed partial response in 16.7%, stable disease in 48.2% and progressive disease in 16.7%. The 1-year survival rate after chemoembolization was 62%, the 2-year survival rate was 28% and the 3-year survival rate was 7%. Median survival from the start of chemoembolization treatment was 14.3 months. The indication (p = 0.001) and initial tumor response (p = 0.015) were statistically significant factors for patient's survival. TACE is a minimally invasive therapy option for controlling local metastases and improving survival time in patients with hepatic metastases from CRC. TN stage, extrahepatic metastases, number of lesions, tumor location within the liver and choice of chemotherapy protocol of TACE are none significant factors for patient's survival.

Abstract
BACKGROUND The optimal timing of surgical resection of liver metastasis remains controversial, and guidelines regarding the upper limits of operative indications have not yet been defined. Surgical indication for metastasis from colorectal cancer (CLM) based on results of preoperative chemotherapy and RNF8 was investigated. METHODS Differences in CLM size on CT were evaluated as shrinkage rate/day by dividing tumor shrinkage rates by the interval in days between CT. Levels of RNF8 of resected colorectal cancer and CLM frozen specimen were detected. RESULTS When the cut line for shrinkage rate at 12 weeks was set at 0.35%, disease-free survival was significantly better in patients with a shrinkage rate >0.35% vs. ≤0.35% (p=0.003). RNF8 expression was significantly higher in Tis (p=0.001). In liver metastasis, RNF8 expression level was significantly lower in patients with partial response to FOLFOX than with stable disease, (p=0.017). CONCLUSIONS A strategy of FOLFOX administration for 12 weeks to patients with low RNF8 expression and hepatectomy planned after 4 weeks rest may be accepted as the best therapeutic option for treating CLM.

Abstract
Colon cancer is seen with increasing frequency in the Asia-Pacific region, and it is one of the most important causes of cancer mortality worldwide. This article reviews the available evidence for optimum management of colon cancer-in particular, with respect to screening and early detection of colon cancer, laparoscopic surgical treatment, adjuvant treatment of individuals with high-risk stage II and stage III cancer, palliative treatment of patients with metastatic disease, and management of resectable and potentially resectable metastases-and how these strategies can be applied in Asian countries with different levels of health-care resources and economic development, stratified by basic, limited, enhanced, and maximum resource levels.

Abstract
PURPOSE Bevacizumab has been shown to increase progression free and overall survival in patients with metastatic colorectal cancer. Neoadjuvant bevacizumab is commonly used in patients undergoing liver resection. Our purpose was to evaluate whether bevacizumab is associated with increased rate of perioperative complications in patients undergoing hepatic resection for colorectal liver metastases (CRLM). METHODS Retrospective analysis of patients undergoing hepatic resection for CRLM who received chemotherapy and bevacizumab (group 1, n = 134), or chemotherapy alone (group 2, n = 57). We compared demographics, surgical characteristics, and perioperative course. RESULTS Perioperative complications developed in 35 % of patients in group 1, and 47 % in group 2 (p = 0.11). Of those complications, 15 (11.2 %) in group 1, and 5 (8.8 %) in group 2 were considered major (p = 0.617). Four patients, all of whom received preoperative bevacizumab, developed enteric leaks following combined liver and bowel resection. The rate of anastomotic leak in group 1 was 10 %, compared with 0 in group 2, p = 0.56. CONCLUSION Neoadjuvant chemotherapy along with bevacizumab was not associated with an increased risk of postoperative complications after hepatic resection. Possible association of increased morbidity with simultaneous bowel and liver resections following bevacizumab administration was found and we recommend avoiding such treatment combination.

Abstract
BACKGROUND Patients with colorectal liver metastases (CLM) are increasingly treated with preoperative chemotherapy. Chemotherapy associated liver injury is associated with postoperative hepatic insufficiency (PHI) and mortality. The adequate minimum future liver remnant (FLR) volume in patients treated with extensive chemotherapy remains unknown. METHODS All patients with standardized FLR > 20 %, who underwent extended right hepatectomy for CLM from 1993-2011, were divided into three cohorts by chemotherapy duration: no chemotherapy (NC, n = 30), short duration (SD, ≤12 weeks, n = 78), long duration (LD, >12 weeks, n = 86). PHI and mortality were compared by using uni-/multivariate analyses. Optimal FLR for LD chemotherapy was determined using a minimum p-value approach. RESULTS A total of 194 patients met inclusion criteria. LD chemotherapy was significantly associated with PHI (NC + SD 3.7 vs. LD 16.3%, p = 0.006). Ninety-day mortality rates were 0 % in NC, 1.3 % in SD, and 2.3% in LD patients, respectively (p = 0.95). In patients with FLR > 30 %, PHI occurred in only two patients (both LD, 2/20, 10 %), but all patients with FLR > 30 % survived. The best cutoff of FLR for preventing PHI after chemotherapy >12 weeks was estimated as >30 %. Both LD chemotherapy (odds ratio [OR] 5.4, p = 0.004) and FLR ≤ 30 % (OR 6.3, p = 0.019) were independent predictors of PHI. CONCLUSIONS Preoperative chemotherapy >12 weeks increases the risk of PHI after extended right hepatectomy. In patients treated with long-duration chemotherapy, FLR > 30 % reduces the rate of PHI and may provide enough functional reserve for clinical rescue if PHI develops.

Abstract
BACKGROUND In 2009, the American Society of Clinical Oncology recommended that patients with metastatic colorectal cancer (mCRC) who are candidates for anti-epidermal growth factor receptor (EGFR) therapy have their tumors tested for KRAS mutations because tumors with such mutations do not respond to anti-EGFR therapy. Limiting anti-EGFR therapy to those without KRAS mutations will reserve treatment for those likely to benefit while avoiding unnecessary costs and harm to those who would not. Similarly, tumors with BRAF genetic mutations may not respond to anti-EGFR therapy, though this is less clear. Economic analyses of mutation testing have not fully explored the roles of alternative therapies and resection of metastases. METHODS This paper is based on a decision analytic framework that forms the basis of a cost-effectiveness analysis of screening for KRAS and BRAF mutations in mCRC in the context of treatment with cetuximab. A cohort of 50 000 patients with mCRC is simulated 10 000 times, with attributes randomly assigned on the basis of distributions from randomized controlled trials. RESULTS Screening for both KRAS and BRAF mutations compared with the base strategy (of no anti-EGFR therapy) increases expected overall survival by 0.034 years at a cost of $22 033, yielding an incremental cost-effectiveness ratio of approximately $650 000 per additional year of life. Compared with anti-EGFR therapy without screening, adding KRAS testing saves approximately $7500 per patient; adding BRAF testing saves another $1023, with little reduction in expected survival. CONCLUSIONS Screening for KRAS and BFAF mutation improves the cost-effectiveness of anti-EGFR therapy, but the incremental cost effectiveness ratio remains above the generally accepted threshold for acceptable cost effectiveness ratio of $100 000/quality adjusted life year.

Abstract
Surgical resection of liver metastases of colorectal cancer can improve clinical outcome and even cure some patients with metastatic disease. For patients with unresectable liver metastases, the ultimate treatment goal is to let them become eligible for resection. In recent years, considerable attention has been paid to molecular targeted therapies to improve the efficacy of the available chemotherapeutic regimens in order to increase the downsizing rate of liver metastases and increase resectability. This overview will focus on the oncological management and chemotherapeutic options of patients with unresectable liver metastases.

Abstract
BACKGROUND When anti-VEGF (vascular endothelial growth factor) antibody bevacizumab is applied in neoadjuvant treatment of colorectal cancer patients with liver metastasis, 5-6 weeks between last bevacizumab dose and liver resection are currently recommended to avoid complications in wound and liver regeneration. In this context, we aimed to determine whether VEGF is inactivated by bevacizumab at the time of surgery. METHODS Fifty colorectal cancer patients with liver metastases received neoadjuvant chemotherapy ± bevacizumab supplementation. The last dose of bevacizumab was administered 6 weeks before surgery. Plasma, subcutaneous and intraabdominal wound fluid were analysed for VEGF content before and after liver resection (day 1-3). Immunoprecipitation was applied to determine the amount of bevacizumab-bound VEGF. RESULTS Bevacizumab-treated individuals showed no increase in perioperative complications. During the entire monitoring period, plasma VEGF was inactivated by bevacizumab. In wound fluid, VEGF was also completely bound by bevacizumab and was remarkably low compared with the control chemotherapy group. CONCLUSION These data document that following a cessation time of 6 weeks, bevacizumab is fully active and blocks circulating and local VEGF at the time of liver resection. However, despite effective VEGF inactivation no increase in perioperative morbidity is recorded suggesting that VEGF activity is not essential in the immediate postoperative recovery period.

Abstract
AIM: To summary our experience with multimodality therapy of unresectable colorectal cancer.
METHODS: A total of 67 patients were included in this study, including 15 patients with right-sided colon cancer, 9 with left-sided colon cancer, and 43 with rectal cancer. All cases were assessed as unresectable by the multidisciplinary team and histologically confirmed as colorectal cancer. Multimodality therapy was performed by colorectal specialists and the multidisciplinary team.
RESULTS: Of all 67 patients, no patients achieved complete remission, 43 achieved partial remission, 16 had stable disease, and 8 had progressive disease. The short-term remission rate was 100%. The survival duration ranged from 10 to 38 months, with an average of 24 months. Nine (13.4%) patients underwent radical surgery. The total complication rate was 52.2% (35/67).
CONCLUSION: Multimodality therapy allows improving quality of life and prolonging survival time in patients with unresectable colorectal cancer.

Abstract
Colorectal cancer is a very common malignancy and frequently manifests with liver metastases, often without other systemic disease. Margin-negative (R0) resection of limited metastatic disease, in conjunction with systemic antineoplastic agents, is the primary treatment strategy, leading to long survival times for appropriately selected patients. There is debate over whether the primary tumor and secondaries should be removed at the same time or in a staged manner. Chemotherapy is effective in converting some unresectable liver metastases into resectable disease, with a correspondingly better survival outcome. However, the ideal chemotherapy with or without biological agents and when it should be administered in the course of treatment are uncertain. The role of neoadjuvant chemotherapy in initially resectable liver metastases is controversial. Local delivery of chemotherapy, with and without surgery, can lead to longer disease-free survival times, but it is not routinely used with curative intent. This review focuses on methods to maximize the disease-free survival interval using chemotherapy, surgery, and local methods.

Abstract
Colorectal cancer is the third most commonly diagnosed cancer with approximately half of the patients developing liver metastases during the course of their disease. Modern multimodal therapies have improved the overall survival. Liver resection remains the most important modality in the treatment of colorectal liver metastases.

Abstract
BACKGROUND Up to 5 per cent of liver resections for colorectal cancer metastases involve the caudate lobe, with cancer-involved resection margins of over 50 per cent being reported following caudate lobe resection. METHODS Outcomes of consecutive liver resections for colorectal metastases involving the caudate lobe between 1996 and 2009 were reviewed retrospectively, and compared with those after liver surgery without caudate resection. RESULTS Twenty-five patients underwent caudate and 432 non-caudate liver resection. Caudate resection was commonly performed as part of extended resection. There were no differences in operative complications (24 versus 21·1 per cent; P = 0·727) or blood loss (median 300 versus 250 ml; P = 0·234). The operating time was longer for caudate resection (median 283 versus 227 min; P = 0·024). Tumour size was larger in the caudate group (median 40 versus 27 mm; P = 0·018). Resection margins were smaller when the caudate lobe was involved by tumour, than in resections including tumour-free caudate or non-caudate resection; however, there was no difference in the proportion of completely excised tumours between caudate and non-caudate resections (96 versus 96·1 per cent; P = 0·990). One-year overall survival rates were 90 and 89·3 per cent respectively (P = 0·960), with 1-year recurrence-free survival rates of 62 and 71·2 per cent (P = 0·340). CONCLUSION Caudate lobe surgery for colorectal cancer liver metastases does not increase the incidence of resection margin involvement, although when the caudate lobe contains metastases the margins are significantly closer than in other resections.

Abstract
Combining surgery and chemotherapy in the treatment of patients with colorectal hepatic metastases is increasingly becoming the standard of care. However, controversy remains regarding the juxtapositioning of chemotherapy and surgery, the duration of chemotherapy, and particularly, the use of preoperative chemotherapy in the treatment of patients with initially resectable metastases. The arguments for and against the different approaches presented are based on the data published in the medical literature and on the data presented at the most recent major oncology meetings, coupled with the personal experience of the authors. For patients with liver metastases that are resectable at presentation, perioperative chemotherapy has become the standard treatment in many institutions, with the recommendation that surgery is performed after a maximum of 6 cycles of systemic therapy. In the case of patients with initially unresectable liver metastases receiving preoperative systemic therapy, patients should be carefully monitored and surgery performed as soon as the metastases become resectable. All patients should, where possible, be treated by a multidisciplinary team. Going forward, it needs to be established whether more intensive treatment (ie, perioperative versus postoperative systemic therapy) is merited for the treatment of patients with initially resectable disease, and what the precise contribution of new therapeutic agents in these settings is, based on new prospective randomized trial data.

Abstract
BACKGROUND The benefit of preoperative chemotherapy in patients with initially resectable liver metastases from colorectal cancer is still a matter of debate. AIMS We aim to evaluate the role of neoadjuvant chemotherapy on the outcome of patients with colorectal cancer metachronous liver metastases undergoing potentially curative liver resection. METHODS One-hundred four patients were available for analysis. Tested variables included age, sex, primary tumour TNM stage, location and grading, the number of liver metastases, monolobar or bilobar location, interval time between liver metastases diagnosis and liver resection, Fong Clinical Risk Score (CRS). Neoadjuvant chemotherapy was administered according to the FOLFOX4 regimen. RESULTS Forty-four patients underwent liver resection without receiving neoadjuvant chemotherapy (group A); 60 patients received neoadjuvant chemotherapy (group B). At univariate analysis, only the time of liver resection seemed to affect overall survival: patients in group A showed a median survival time significantly superior to that of patients in group B (48 vs. 31 months; p=0.0358). CONCLUSIONS Our findings suggest that, when feasible, resection of liver metastases should be considered as an initial approach in this setting. Further studies are needed to better delineate innovative therapeutic strategies that may lead to an improved outcome for colorectal cancer patients with surgically resectable liver metastases.

Abstract
In the treatment of metastatic colorectal cancer, the subset of patients with liver-only metastases shows the greatest promise for prolonged survival and cure. Advances in surgery and medical treatment have encouraged multimodality treatment strategies and therefore require a true multidisciplinary approach. The current standard of care includes peri-operative chemotherapy and surgery. The new era of biologically targeted therapy requires an in-depth look at the possible efficacy and risks of adding these agents to the treatment protocol.
