Abstract
BACKGROUND Angiotensin-converting enzyme (ACE) inhibitors have been shown to possibly influence the survival outcomes in certain cancers. The aim of this study was to evaluate the impact of ACE inhibitors on the outcomes of patients undergoing liver resection for colorectal liver metastases (CRLM). The secondary aim was to determine whether ACE inhibitors influenced histopathological changes in CRLM. METHODS Patients treated with liver resection for CRLM over a 13-year period were identified from a prospectively maintained database. Data including demographics, primary tumour treatment, surgical data, histopathology analysis and clinical outcome were collated and analysed. RESULTS A total of 586 patients underwent primary hepatic resections for CRLM during this period including 100 patients on ACE inhibitors. The median follow-up period was 23 (range: 12-96) months, in which 267 patients developed recurrent disease and 131 patients died. Independent predictors of disease-free survival on multivariate analysis included synchronous presentation, neoadjuvant chemotherapy, major liver resection, tumour size and number, extent of hepatic steatosis, R0 resection and presence of perineural invasion. Poorer overall survival was associated with neoadjuvant treatment, major liver resection, presence of multiple metastases, perineural invasion and positive resection margins on multivariate analysis. ACE inhibitors did not influence the survival outcome or histological presentation in CRLM. CONCLUSION The use of ACE inhibitors did not affect the survival outcome or tumour biology in patients with CRLM following liver resection.

Tumor burden as possible biomarker of outcome in advanced NSCLC patients treated with immunotherapy: a single center, retrospective, real-world analysis. EXPLORATION OF TARGETED ANTI-TUMOR THERAPY 2021; 2:227-239. [PMID: 36046436 PMCID: PMC9400786 DOI: 10.37349/etat.2021.00043] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Accepted: 04/19/2021] [Indexed: 11/19/2022] Open
Abstract
Aim: The role of tumor burden (TB) for patients with non-small cell lung cancer (NSCLC) receiving immunotherapy is still unknown. The aim of this analysis was to analyze the prognostic value of TB in a real-world sample of advanced NSCLC patients. Methods: Sixty-five consecutive patients with advanced NSCLC treated with immunotherapy as first or second line therapy were retrospectively analyzed between August 2015 and February 2018. TB was recorded at baseline considering sites and number of metastases, thoracic vs. extrathoracic disease, measurable disease (MD) vs. not-MD (NMD) and evaluating dimensional aspects as maximum lesion diameter (cut-off = 6.3 cm), sum of the 5 major lesions diameters (cut-off = 14.3 cm), and number of sites of metastases (cut-off > 4). All cut-offs were calculated by receiver operating characteristic curves. Median overall survival (OS) was estimated using Kaplan-Meier method. A Cox regression model was carried out for univariate and multivariate analyses. Results: Median age was 70 years and most patients (86.2%) had a good performance status (PS-Eastern Cooperative Oncology Group < 2). No significant difference in OS was noted between subgroups of patients according to TB. Bone metastases (BM) had a negative prognostic impact [median OS (mOS), 13.8 vs. 70.0 months, P = 0.0009; median progression free survival in the second line (mPFS2) 2.97 vs. 8.63 months; P = 0.0037]. Patients with NMD had a poorer prognosis (mOS, 15.9 months vs. not reached, P < 0.0001; mPFS2 3.8 vs. 12.2 months; P = 0.0199). Patients with disease limited to the thorax had a better prognosis compared to patients with involvement of extrathoracic sites (mOS, 70 vs. 17.3 months; P = 0.0136). Having more than 4 metastatic sites resulted as a negative prognostic factor (mOS, 15.9 vs. 25.2 months; P = 0.0106). At multivariate analysis, BM, NMD, extrathoracic disease and number of sites of metastases > 4 were negative prognostic factors (P < 0.0001). Conclusions: This study underlines the negative prognostic impact of specific metastatic sites, presence of NMD and extrathoracic disease in advanced NSCLC patients treated with immunotherapy. However, TB does not appear to affect the outcome of these patients.

Histopathological growth patterns and positive margins after resection of colorectal liver metastases. HPB (Oxford) 2020; 22:911-919. [PMID: 31735649 PMCID: PMC7888172 DOI: 10.1016/j.hpb.2019.10.015] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2019] [Revised: 08/23/2019] [Accepted: 10/03/2019] [Indexed: 12/12/2022]
Abstract
BACKGROUND Histopathological growth patterns (HGPs) of colorectal liver metastases (CRLM) may be an expression of biological tumour behaviour impacting the risk of positive resection margins. The current study aimed to investigate whether the non-desmoplastic growth pattern (non-dHGP) is associated with a higher risk of positive resection margins after resection of CRLM. METHODS All patients treated surgically for CRLM between January 2000 and March 2015 at the Erasmus MC Cancer Institute and between January 2000 and December 2012 at the Memorial Sloan Kettering Cancer Center were considered for inclusion. RESULTS Of all patients (n = 1302) included for analysis, 13% (n = 170) had positive resection margins. Factors independently associated with positive resection margins were the non-dHGP (odds ratio (OR): 1.79, 95% confidence interval (CI): 1.11-2.87, p = 0.016) and a greater number of CRLM (OR: 1.15, 95% CI: 1.08-1.23 p < 0.001). Both positive resection margins (HR: 1.41, 95% CI: 1.13-1.76, p = 0.002) and non-dHGP (HR: 1.57, 95% CI: 1.26-1.95, p < 0.001) were independently associated with worse overall survival. CONCLUSION Patients with non-dHGP are at higher risk of positive resection margins. Despite this association, both positive resection margins and non-dHGP are independent prognostic indicators of worse overall survival.

Abstract
BACKGROUND The prognostic significance of the platelet (PLR) and neutrophil (NLR) to lymphocyte ratios for patients with resectable colorectal cancer liver metastases (CLM) was evaluated. METHODS Clinicopathologic data from patients who underwent hepatectomy for CLM at two tertiary care hospitals between 1995 and 2017 were collected. Blood counts were evaluated for prognostic significance. RESULTS 151 patients met inclusion criteria. The median age was 58 years, 44% were female, and 58% had synchronous metastases. Median number of liver metastases was 2, and 59% of patients underwent lobectomy or extended lobectomy. On multivariable analysis, NLR ≥5 (HR 2.46 [1.08-5.60 CI], p = 0.032), PLR ≥ 220 (HR 2.10 [1.04-4.23 CI], p = 0.037), and greater than 2 liver metastases (HR 2.41 [1.06-5.45 CI], p = 0.035) were associated with reduced overall survival. CONCLUSIONS PLR ≥ 220 and NLR ≥ 5 may have utility as preoperative prognostic markers for overall survival in patients with resectable CLM.

Abstract
BACKGROUND Above and beyond their role in cardiovascular risk reduction, statins appear to have a chemopreventive role in some gastro-intestinal cancers. In the quest for new chemopreventive agents, some existing established drugs such as statins have shown potential for re-purposing as chemoprevention. Probing existing drugs, whose pharmacodynamics are familiar, for novel beneficial effects offers a more cost-effective and less time-consuming strategy than establishing brand new drugs whose pharmacodynamic profile is unfamiliar. Observational studies show statins decrease the risk of developing colorectal cancer but there are no published studies exploring the potential impact of statins on carcinogenesis in colorectal liver metastases (CRLM).
AIM To evaluate impact of statins on outcomes of CRLM resection, and secondarily to assess if statins influence CRLM histo-pathology.
METHODS We conducted a retrospective cohort study of patients operated for CRLM over a 13-year period from 2005 to 2017. Patients were identified from a prospective database maintained in our Tertiary care hospital. All 586 patients included the study had undergone resection of CRLM following discussion at multidisclipinary team meeting, some patients requiring neoadjuvant chemotherapy to downstage CRLM prior to surgery. We analysed patient demographics, operative details, CRLM histopathology, Index of Deprivation, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio and chemotherapy use in relation to clinical outcome. Statistics were performed using SPSS version 16.0; significance taken at 5%.
RESULTS Liver resection for CRLM was undertaken in 586 patients at a median age of 68 (range 19 to 88) years. Statin therapy was used by 181 patients. Median follow-up time was 23 (range 12-96) mo and further colorectal cancer metastases developed in 267 patients. A total of 131 patients died. Multi-variate analysis identified 6 independent predictors of poorer disease-free survival: Synchronous presentation, multiple tumours, tumour size ≥ 5 cm, moderate–severe steatosis, peri-neural invasion, and R1-resection margin. Poorer overall survival was significantly associated with neo-adjuvant chemotherapy, major hepatectomy, peri-neural invasion and R1-resection margin. Neither histo-pathological nor radiological traits of CRLM were affected by statins, and, there was no demonstrable effect of statin therapy on patient outcomes.
CONCLUSION Statin therapy does not affect patient survival following liver resection for CRLM. We postulate the reason for this key finding is that statins do not modulate tumour biology of CRLM.

Abstract
Introduction The aim of this study was to determinate the outcome of indeterminate liver lesions on computed tomography (CT) in patients with a background history of colorectal cancer (CRC) and to identify clinicopathological variables associated with malignancy in these lesions. A secondary aim was to devise a management algorithm for such patients. Methods Patients referred to our institution with indeterminate liver lesions on CT with a background history of CRC between January 2012 and December 2014 were included in the study. Clinicopathological factors, surveillance period and histological findings were analysed. Results Fifty-six patients with indeterminate liver lesions were identified. Fifty-three (94.6%) of these required further imaging (magnetic resonance imaging [MRI; n=50] and positron emission tomography combined with CT [n=3]). For the patients who had MRI, the underlying diagnosis was benign in 19 and colorectal liver metastasis (CRLM) in 8 while 23 patients and an indeterminate lesion. In cases that remained indeterminate following MRI, liver resection was performed in 2 patients for a high suspicion of CRLM while the 21 remaining patients underwent interval surveillance (median: 9 months, range: 3-52 months). Of these 21 patients, 14 had benign lesions while CRLM was noted in 6 patients and an incidental hepatocellular carcinoma in a single patient. Age ≥65 years was the only statistically significant clinicopathological factor in predicting an underlying malignancy in patients with indeterminate liver lesions on CT. Conclusions Over a third of the patients diagnosed with indeterminate liver lesions on CT subsequently showed evidence of CRLM. These indeterminate lesions are more likely to be malignant in patients aged ≥65 years.

Abstract
AIM To evaluate the impact of anti-platelet therapy on the outcomes of patients undergoing liver resection for CRLM. Secondary aim was to determine whether anti-platelet therapy influenced histo-pathological changes in CRLM. METHODS Patients treated with liver resection for CRLM were identified from a prospectively maintained hepatobiliary database during an 11-year period. Collated data included demographics, primary tumour treatment, surgical data, histopathology analysis and clinical outcome. RESULTS 454 patients that underwent primary hepatic resections for CRLM were included. 60 patients were on anti-platelet therapy. 241 patients developed recurrent disease and 131 patients have died. Multi-variate analysis identified 4 independent predictors of disease-free survival: tumour number; tumour size; peri-neural invasion; and resection margin. The presence of peri-neural invasion and multiple hepatic metastases were independent predictors of poorer overall survival on multi-variate analysis. Uni-variate analysis showed that the use of anti-platelet therapy was associated with larger tumour size (p=0.031) and vascular invasion (p=0.023). CONCLUSION Anti-platelet therapy does not affect the survival outcome in patients with CRLM following liver resection. Anti-platelet therapy is associated with larger liver metastases and vascular invasion on histo-pathological analysis. SYNOPSIS A large retrospective study looking at outcomes of patients taking pre operative anti platelet therapy who have undergone liver resection for colorectal liver metastases.

Abstract
BACKGROUND Although the prognostic role of surgical margin status after resection of colorectal liver metastasis (CRLM) has been previously examined, controversy still surrounds the importance of surgical margin status in patients with multiple tumors. METHODS Patients who underwent curative-intent surgery for CRLM from 2000 to 2015 and who presented with multiple tumors were identified. Patients with R1 resection status determined by the closest resection margin of the non-largest tumor were classified as R1-Type 1; patients with R1 status determined by the resection margin of the largest tumor were defined as R1-Type 2. Data regarding surgical margin status, size of tumors, and overall survival (OS) were collected and assessed. RESULTS A total of 251 patients met inclusion criteria; 156 patients (62.2%) had a negative margin (R0), 50 had an R1-type 1 (19.9%), and 45 had an R1-type 2 (17.9%) margin. Median and 5-year OS in the entire cohort was 56.4 months and 48.0%, respectively. When all R1 (Type 1 + Type 2) patients were compared with R0 patients, an R1 was not associated with worse prognosis (P = 0.05). In contrast, when R1-type 2 patients were compared with R0 patients, an R1 was strongly associated with worse OS (P = 0.009). On multivariate analysis, although the prognostic impact of all R1 was not associated with OS (hazard ratio [HR] 1.56; P = 0.08), R1-Type 2 margin status independently predicted a poor outcome (HR 1.93; P = 0.03). CONCLUSIONS The impact of margin status varied according to the size of the tumor assessed. While R1 margin status defined according to the non-largest tumor was not associated with OS, R1 margin status relative to the largest index lesion was associated with prognosis.

Abstract
BACKGROUND Hepatic resectional surgery remains a highly specialized area of general surgery usually reserved for completion at tertiary metropolitan referral centres. Port Macquarie, on the Mid North Coast of New South Wales, is the only regionally based hospital offering surgery of this nature in mainland Australia. The purpose of this study is to review the data for patients undergoing hepatic resectional surgery in this non-metropolitan centre in order to illustrate that these operations can be carried out safely in a regional setting with comparable results to tertiary-level centres. METHODS A retrospective review of consecutive patients undergoing elective hepatic resections at Port Macquarie from February 2008 to 31 October 2015 was completed. Pre-morbid patient clinical and demographic factors, histopathological details, post-operative complications, survival and mortality data were all noted. RESULTS A total of 66 consecutive elective liver resections were performed during the study period. Metastatic colorectal cancer was the most commonly observed pathology (n = 33, 50.0%). The 90-day mortality was 4.5% (n = 3) whilst 17 patients (n = 17, 25.8%) experienced major complications (Clavien-Dindo grade 3 or 4). The median overall survival following hepatectomy for colorectal metastases was 48 months (95% confidence interval 37-59 months). CONCLUSION Our study shows excellent morbidity, mortality and survival for hepatic resectional surgery performed in a regional centre and is comparable data to major metropolitan centres. Our study confirms that major hepatic resectional surgery in this setting is safe and effective.

Prognostic Significance of Neutrophil-to-Lymphocyte Ratio in Colorectal Liver Metastasis: A Systematic Review and Meta-Analysis. PLoS One 2016; 11:e0159447. [PMID: 27427969 PMCID: PMC4948783 DOI: 10.1371/journal.pone.0159447] [Citation(s) in RCA: 36] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2016] [Accepted: 07/04/2016] [Indexed: 12/21/2022] Open
Abstract
Background and Objective Inflammation is deemed to play critical roles in tumor progression and metastasis, and an increased neutrophil-lymphocyte ratio (NLR) has been reported to correlate with poor survivals in various malignancies. However, association between NLR elevation and survival outcome in patients with colorectal liver metastasis (CRLM) remains controversial. The aim of this study was to investigate the prognostic significance of elevated NLR in CRLM. Methods The meta-analysis was conducted in adherence to the MOOSE guidelines. PubMed, Embase, Cochrane Library, Web of Science and the Chinese SinoMed were systematically searched to identify eligible studies from the initiation of the databases to May, 2016. Overall survival (OS) and recurrence free survival (RFS) were pooled by using hazard ratio (HR) with corresponding 95% confidence interval (CI). Correlation between NLR values and clinicopathological features was synthesized by using odds ratio (OR) with corresponding 95% CI. Results A total of 1685 patients from 8 studies (9 cohorts) were analyzed, consisting 347 (20.59%) in high pretreatment NLR value group and 1338 (79.41%) in low pretreatment NLR value one. The results demonstrated that elevated pretreatment NLR was significantly related to poor OS (HR 2.17, 95% CI 1.82–2.58) and RFS (HR 1.96, 95% CI 1.64–2.35) in patients with CRLM. Conclusion The result of this systematic review and meta-analysis indicated that an elevated pretreatment NLR was closely correlated with poor long-term survival (OS and RFS) in CRLM patients. NLR can be routinely monitored and serve as a useful and cost-effective marker with strong prognostic significance in patients with CRLM.

Abstract
Patients with encapsulated colorectal liver metastases (CRLM) have a better prognosis than those without a capsule. The reason for the encapsulation is unknown. Hypoxia inducible factor-1α (HIF-1α) increases tumor angiogenesis and tumor tissue expression is associated with reduced survival. Our aim was to determine whether the good prognosis of encapsulated CRLM is associated with reduced HIF-1α expression by the cancer.The study selected only patients who had not undergone neoadjuvant chemotherapy prior to a potentially curative hepatectomy for CRLM. From 30 selected patients, serial sections were cut from a single randomly selected metastasis. Morphology was assessed following H&E staining. Tumor hypoxia, vascular endothelial growth factor (VEGF), proliferation, and microvascular density (MVD) were assessed by immunostaining for HIF-1α and carbonic anhydrase-9 (CA-9), VEGF, Ki67, and cluster of differentiation-31, respectively. MVD was calculated in the vascular hot spots. Pathology was reported without clinical outcome information. Actual long-term survival was recorded.Thirteen (43%) of the cancers were encapsulated CRLM containing glands which were large, complex, and cribriform. Thirteen (43%) were infiltrative CRLM and their glands were small, closely packed, and rounded with vessels in the interglandular fibrous tissue with no capsule; 3 (10%) had a mixed picture. Encapsulated CRLM had a higher expression of HIF-1α (58% vs 8%, P = 0.03), CA-9 (42% vs 0%, P = 0.04), and VEGF (92% vs 25%, P = 0.02). MVD was lower in the encapsulated CRLM group (37 mm vs 143 mm, P < 0.001). The median follow-up was 115 months. The encapsulated CRLM group had a better overall and 5-year survival (relative hazard: 0.58, P = 0.057 and hazard ratio: 0.52, P = 0.044).There are 2 main morphological appearances of CRLM which have very different long-term survival following liver resection surgery. The morphology is associated with differences in expression of HIF-1α, CA-9, VEGF, and angiogenesis.

Abstract
OBJECTIVE The aim of this study was to determine the value of SUV-based metabolic parameters derived from pretreatment F-FDG PET/CT of colorectal liver metastases in predicting disease response, progression-free survival (PFS), and overall survival (OS). PATIENTS AND METHODS We retrospectively reviewed 70 colorectal patients with liver metastases who underwent pretreatment F-FDG PET/CT. SUVmean, SUVmax, TLG (total lesion glycolysis), metabolic tumor volume, and metabolic tumor diameter were the metabolic parameters derived from volume of interest analysis of the most FDG-avid liver lesion in each subject. Clinical and laboratory parameters were recorded. Tumor response was assessed by response evaluation criteria in solid tumors 1.1 criteria at 12 weeks after treatment. Associations between tumor response, metabolic parameters, and clinical/laboratory parameters were examined by 1-way analysis of variance. The relationship of the metabolic parameters with PFS and OS was determined by Kaplan-Meier analyses and further confirmed with multivariate Cox regression analyses. RESULTS SUVmean less than 4.48, SUVmax less than 6.59, TLG less than 75.2, metabolic tumor volume less than 4.49 cm, and hemoglobin level greater than or equal to 11 g/dL were associated with longer PFS (P < 0.05). Prior surgery or radiofrequency ablation to the liver metastases was the only additional factor shown to be associated with longer OS. CONCLUSIONS SUV-based metabolic parameters derived from pretreatment F-FDG PET/CT can predict PFS in colorectal liver metastases.

Abstract
BACKGROUND This study aimed to determine the prognostic value of a novel grading system based on the histologic assessment of poorly differentiated clusters (PDCs) in the primary lesions in patients with hepatectomy for colorectal liver metastasis (CRLM). Preoperative survival predictors for CRLM are required to determine candidates for perioperative chemotherapy who would otherwise have a poor prognosis. METHODS In total, 411 consecutive patients undergoing curative resection of primary colorectal cancers and metastatic liver lesions at 2 institutions were enrolled. Cancer clusters comprising ≥ 5 cancer cells, lacking a gland-like structure, were defined as PDCs and quantifiably graded. RESULTS According to PDCs, 65, 127, and 219 patients were classified as being grades (G)1, G2, and G3, respectively. PDCs were associated with T and N stages and tumor budding in primary tumor, extrahepatic disease, and serum CEA levels (P ≤ .0001-.045), but not with the number and size of liver metastasis. PDC grade significantly influenced recurrence rate in extrahepatic sites, including the lung and peritoneum (P < .0001). The 2-year disease-free survival after hepatectomy was 64.6%, 38.8%, and 22.4% in G1, G2, and G3, respectively. Based on multivariate analysis, PDC grade was selected as an independent prognostic factor together with other conventional factors such as extrahepatic disease and the number of liver metastasis. CONCLUSION PDC grade in primary lesions is a novel potent prognostic indicator in CRLM independent of the anatomic extent of disease. Notably, PDC grade can bias survival rates in clinical studies targeting perioperative chemotherapy in CRLM.

Abstract
BACKGROUND Advances in multidisciplinary care are changing the prognostic impact of colorectal lung metastases. Resection of colorectal liver metastases (CLM) may benefit patients with synchronous lung metastases even when lung metastases are not resected. The aim of this study was to investigate the survival of patients undergoing complete resection of CLM in the setting of unresected lung metastases. PATIENTS AND METHODS We compared survival among 98 patients who underwent resection of CLM with unresected lung metastases, 64 who received only chemotherapy for limited colorectal liver and lung metastases, and 41 who underwent resection of both liver and lung metastases. Prognostic factors were investigated in the patients who underwent resection of CLM only. RESULTS The 3-year/5-year overall survival (OS) rates of patients with CLM resection only (42.9 %/13.1 %) were better than those of patients treated with chemotherapy only (14.1 %/1.6 %; p < 0.01) but worse than those of patients with resection of liver and lung metastases (68.9 %/56.9 %; p < 0.01). Multivariate analysis of patients with CLM resection only revealed that KRAS mutation [hazard ratio (HR) 2.10; 95 % confidence interval (CI) 1.21-3.64; p < 0.01] and rectal primary tumor (HR 1.72; 95 % CI 1.02-2.88; p = 0.04) were independent predictors of worse OS. Survival of patients without these risk factors was similar to that of patients with curative metastasectomy. CONCLUSIONS Complete resection of metastases remains the primary goal of treatment for stage IV colorectal cancer. Resection of CLM without resection of lung metastases is associated with an intermediate survival between that of patients treated with palliative and curative intent and should be considered in selected patients.

Abstract
Purpose Colorectal cancer patients with liver-confined metastases are classified as stage IV, but their prognoses can differ from metastases at other sites. In this study, we suggest a novel method for risk stratification using clinically effective factors. Materials and Methods Data on 566 consecutive patients with colorectal liver metastasis (CLM) between 1989 and 2010 were analyzed. This analysis was based on principal component analysis (PCA). Results The survival rate was affected by carcinoembryonic antigen (CEA) level (p < 0.001; risk ratio, 1.90), distribution of liver metastasis (p=0.014; risk ratio, 1.46), and disease-free interval (DFI; p < 0.001; risk ratio, 1.98). When patients were divided into three groups according to PCA score using significantly affected factors, they showed significantly different survival patterns (p < 0.001). Conclusion The PCA scoring system based on CEA level, distribution of liver metastasis, and DFI may be useful for preoperatively determining prognoses in order to assist in clinical decisionmaking and designing future clinical trials for CLM treatment.

Abstract
OBJECTIVE The aim of this study was to identify prognostic factors, particularly pathological variables, that influence disease-free and overall survival following resection for colorectal liver metastases (CRLM). METHODS Patients undergoing CRLM resection from January 2005 to December 2011 were included. Data analysed included information on demographics, laboratory results, operative findings, histopathological features and survival. RESULTS A total of 259 patients were included. Of these, 138 (53.3%) patients developed recurrent disease, of which 95 died. The median length of follow-up in the remaining patients was 28 months (range: 12-96 months). There were significant associations between recurrence and higher tumour number (P = 0.002), presence of perineural invasion (P = 0.009) and positive margin (R1) resection (P = 0.002). Multivariate analysis showed all three prognostic factors to be independent predictors of disease-free survival. Significantly poorer overall survival after hepatic resection for CRLM was observed in patients undergoing hemi-hepatectomy or more radical resection (P = 0.021), patients with a higher number of tumours (P = 0.024) and patients with perineural invasion (P < 0.001). Multivariate analysis showed perineural invasion to be the only independent predictor of overall survival. CONCLUSIONS The presence of perineural invasion, multiple tumours and an R1 margin were associated with recurrent disease. Perineural invasion was also an independent prognostic factor with respect to overall survival.

Abstract
Purpose Hepatic resection is a standard method of treatment for colorectal liver metastases (CRLM). However, the pathologic factors of metastatic lesions that affect tumor recurrence are less well defined in CRLM. The aim of this study was to evaluate the risk factors for recurrence of CRLM, focusing on histopathologic factors of metastatic lesions of the liver. Methods From January 2003 to December 2008, 117 patients underwent curative hepatic resection for CRLM were reviewed. Tumor size and number, differentiation, tumor budding, angio-invasion, dedifferentiation and tumor infiltrating inflammation of metastatic lesions were investigated. Results The mean number of hepatic tumors was 2 (range, 1-8). The mean size of the largest tumor was 2.9 cm (range, 0.3-18.5 cm) in diameter. The moderate differentiation of the hepatic tumor was the most common in 86.3% of the patients. Tumor budding, angio-invasion, and dedifferentiation were observed in 81%, 34%, and 12.8% of patients. Inflammation infiltrating tumor was detected in 6.8% of patients. Recurrence after hepatic resection appeared in 69 out of 117 cases (58.9%). Recurrence-free survival at 1, 2 and 5 years were 62.4%, 43.6%, and 34.3%. The multivariate analysis showed the number of metastases ≥3 (P = 0.007), the tumor infiltrating inflammation (P = 0.047), and presence of dedifferentiation (P = 0.020) to be independent risk factors for tumor recurrence. Conclusion Histopathological factors, i.e., dedifferentiation and tumor infiltrating inflammation of the metastatic lesion, could be one of the risk factors of aggressive behavior as well as the number of metastases even after curative resection for CRLM.

Abstract
INTRODUCTION The aim of this study was to analyse the influence of factors reported in the minimum histopathology dataset for colorectal liver metastases (CRLM) and other pre-operative factors compared with additional data relating to the presence of tumour pseudocapsules and necrosis on recurrence 1 year after a resection. METHODS For a period of 14 months, extended histological reporting of CRLM specimens was performed, including the presence of pseudocapsules and necrosis in each tumour. The details of recurrence were obtained from surveillance imaging. RESULTS In 66 patients there were 27 recurrences within 1 year. The rates were lower for patients with tumour pseudocapsules (8/27) than for patients without (19/36) (P = 0.030). Pseudocapsules were associated with a younger age (P = 0.005), nodal stage of the primary colorectal tumour (P = 0.025) and metachronous tumours (P = 0.004). In patients with synchronous disease and pseudocapsules, the recurrence rate was 2/12 compared with 13/23 patients without pseudocapsules (P = 0.026). DISCUSSION These findings demonstrate that histological examination of resection specimens can provide significant additional prognostic information for patients after resection of CRLM, compared with clinical and radiological data. The present finding that the absence of a pseudocapsule in patients with synchronous CRLM is associated with a dramatically worse outcome may help direct patient-specific adjuvant treatment and care.

Abstract
PURPOSE The aim of the present study was to determine selection criteria for patients with stage IV colorectal cancer (CRC) who were likely to show survival benefits of metastasectomy. METHODS Clinicopathological data of 119 patients with stage IV CRC who underwent primary CRC resection were retrospectively reviewed. The prognostic factors were analyzed according to the disease resectability status, and patients likely to show survival benefits of metastasectomy were identified. RESULTS Metastasectomy was performed in 63 patients. Among these patients, R0 resection was reported in 55 patients, who comprised the curable group. The other 64 patients comprised the noncurable group. For the noncurable group, postoperative chemotherapy was identified as the only significant prognostic factor. In the curable group, T stage, histological type, elevated serum carcinoembryonic antigen (CEA) level and the presence of extra hepatic disease were identified as independent prognostic factors. Patients within the curable group were further classified into a low-risk group (zero to two prognostic factors) and a high-risk group (three or more prognostic factors). The overall survival (OS) of the high risk patients in the curable group was as poor as that of the patients in the noncurable group. CONCLUSIONS Stage IV CRC patients consisted of heterogeneous populations who had different prognostic factors, stratified by the disease resectability status. No prognostic benefit of metastasectomy was observed in high-risk patients undergoing curative metastasectomy. These results suggested that patients showing survival benefits of metastasectomy can be identified by considering the prognostic factors in patients undergoing curative metastasectomy.

Son SY, Yi NJ, Hong G, Kim H, Park MS, Choi YR, Suh KS, Kim DW, Jeong SY, Park KJ, Park JG, Lee KU. Is neoadjuvant chemotherapy necessary for patients with initially resectable colorectal liver metastases in the era of effective chemotherapy? KOREAN JOURNAL OF HEPATO-BILIARY-PANCREATIC SURGERY 2011; 15:206-17. [PMID: 26421041 PMCID: PMC4582468 DOI: 10.14701/kjhbps.2011.15.4.206] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/17/2011] [Revised: 10/04/2011] [Accepted: 10/21/2011] [Indexed: 12/21/2022]
Abstract
Backgrounds/Aims Hepatic resection has only guaranteed long-term survival in patients with colorectal liver metastasis (CRLM) even in the era of effective chemotherapy. The definite role of neoadjuvant chemotherapy (NCT) is to improve outcomes of unresectable CRLMs, but it its role has not been defined for initially resectable CRLMs (IR-CRLMs). Methods We reviewed the medical records of 226 patients, who had been diagnosed and treated for IR-CRLM between 2003 and 2008; the patients had the following pathologies: 10% had more than 4 nodules, 11% had tumors larger than 5 cm, and 61% had synchronous CRMLs. Among these patients, 20 patients (Group Y) were treated with NCT, and 206 (Group N) did not receive NCT according to their physician's preference. The median follow-up time was 34.1 months. Results The initial surgical plans were changed after NCT to further resection in 20% and to limited resection in 10% of 20 patients. Complication rates of Groups Y (30%) were indifferent from Group N (23%) (p=0.233), but intraoperative transfusions were more frequent in Group N (15%) than in Group Y (5%) (p=0.006). There was one case of hospital mortality (0.44%). Disease-free survival rates in Groups Y and N were 23% and 39%, respectively, and patient survival rates were 42% and 66% (p>0.05). By multivariate analysis, old age (≥60 years), differentiation of primary tumor (poorly/mucinous), resection margin involvement, and no adjuvant chemotherapy were associated with poor patient survival; the number of CRLMs (≥4) was associated with poor disease-free survival. Conclusions NCT had neither a positive impact nor a negative impact on survival, even with intraoperative transfusion, as observed on operative outcomes for patients with IR-CRLM. Further study is required to elucidate the role of NCT for treatment of patient with IR-CRLMs.
