Abstract
Computational Pathology (CPath) is an interdisciplinary science that augments developments of computational approaches to analyze and model medical histopathology images. The main objective for CPath is to develop infrastructure and workflows of digital diagnostics as an assistive CAD system for clinical pathology, facilitating transformational changes in the diagnosis and treatment of cancer that are mainly address by CPath tools. With evergrowing developments in deep learning and computer vision algorithms, and the ease of the data flow from digital pathology, currently CPath is witnessing a paradigm shift. Despite the sheer volume of engineering and scientific works being introduced for cancer image analysis, there is still a considerable gap of adopting and integrating these algorithms in clinical practice. This raises a significant question regarding the direction and trends that are undertaken in CPath. In this article we provide a comprehensive review of more than 800 papers to address the challenges faced in problem design all-the-way to the application and implementation viewpoints. We have catalogued each paper into a model-card by examining the key works and challenges faced to layout the current landscape in CPath. We hope this helps the community to locate relevant works and facilitate understanding of the field's future directions. In a nutshell, we oversee the CPath developments in cycle of stages which are required to be cohesively linked together to address the challenges associated with such multidisciplinary science. We overview this cycle from different perspectives of data-centric, model-centric, and application-centric problems. We finally sketch remaining challenges and provide directions for future technical developments and clinical integration of CPath. For updated information on this survey review paper and accessing to the original model cards repository, please refer to GitHub. Updated version of this draft can also be found from arXiv.

Abstract
Colorectal liver metastasis (CRLM) appears in 25-50% of patients with colorectal cancer (CRC). However, CRLM with bile duct tumor thrombus (BDTT) is rare and often diagnosed after surgical resection. We report a case of CRLM associated with BDTT in a 79 year-old woman. She underwent sigmoid colectomy for sigmoid colon carcinoma at the age of 64. Fifteen years later, abdominal computed tomography revealed a liver tumor with a biliary tumor thrombus in segment IV/V and localized dilation of the intrahepatic bile duct. Additionally, magnetic resonance imaging confirmed a tumor in liver segment IV/V and mass in the bile duct (B4). Extended left hepatic lobectomy was performed under the diagnosis of intrahepatic cholangiocarcinoma or metastatic liver tumor with tumor development in the intrahepatic bile duct. The resected specimen showed significant cancer infiltration into the intrahepatic bile duct (B4), forming a tumor thrombus. The tumor was a moderately differentiated adenocarcinoma, histologically similar to sigmoid colon cancer. CRLM with BDTT may have a relatively low invasive potential of malignancy with a long interval after primary resection. When a patient with a history of CRC presents with BDTT, the possibility of CRLM with BDTT and surgical treatment should be considered, because resection could lead to a good prognosis. It is important to ensure a secure surgical margin in the bile ducts during surgery and anatomical hepatic resection should be considered.

Abstract
Simple Summary Researchers have shown that tumor biomarkers and increased nerve density are important clinical tools for determining cancer prognosis and developing effective treatments. The aims of our review were to synthesize these findings by detailing the histology of peripheral nerves, discuss the use of various neuronal biomarkers in cancer, and assess the impact of increased nerve density on tumorigenesis. This review demonstrates that specific neuronal markers may have an important role in tumorigenesis and may serve as diagnostic and prognostic factors for various cancers. Moreover, increased nerve density may be associated with worse prognosis in different cancers, and cancer therapies that decrease nerve density may offer benefit to patients. Abstract Certain histologic characteristics of neurons, novel neuronal biomarkers, and nerve density are emerging as important diagnostic and prognostic tools in several cancers. The tumor microenvironment has long been known to promote tumor development via promoting angiogenesis and cellular proliferation, but new evidence has shown that neural proliferation and invasion in the tumor microenvironment may also enable tumor growth. Specific neuronal components in peripheral nerves and their localization in certain tumor sites have been identified and associated with tumor aggressiveness. In addition, dense neural innervation has been shown to promote tumorigenesis. In this review, we will summarize the histological components of a nerve, explore the neuronal biomarkers found in tumor sites, and discuss clinical correlates between tumor neurobiology and patient prognosis.

Prognostic significance of intrahepatic lymphatic invasion in colorectal liver metastases. Ann Diagn Pathol 2022; 60:152026. [PMID: 35988375 DOI: 10.1016/j.anndiagpath.2022.152026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Revised: 08/07/2022] [Accepted: 08/13/2022] [Indexed: 11/01/2022]
Abstract
BACKGROUND Intrahepatic lymphatic invasion is an adverse prognostic factor after hepatectomy for colorectal liver metastases (CLMs). However, most patients in previous reports had liver resection before the era of FOLFOX/FIRI-based chemotherapy. METHODS Forty-six patients who underwent hepatectomy for CLMs from 2004 to 2020 were evaluated. We histologically evaluated portal invasion, intrahepatic lymphatic invasion, and biliary invasion on hematoxylin-eosin slides. We also collected the following clinicopathologic factors: gender, age, timing, the number and maximum size of CLMs, preoperative tumor markers, neutrophil/lymphocyte ratio, location, and lymph node metastases of primary cancer, and chemotherapy after hepatectomy. A multivariate Cox proportional hazard model was used to define the relationship between overall (OS) or disease-free survival (DFS) and clinicopathologic factors. RESULTS Histological invasions were portal invasion in 8 (17.4 %), intrahepatic lymphatic invasion in 6 (13.0 %), and biliary invasion in 5 (10.9 %). Chemotherapy for recurrence after hepatectomy (n = 29) was performed in 22 and 14 of those who received FOLFOX/FIRI-based chemotherapy. By multivariate analysis, the number of CLMs (p < 0. 01) and presence of intrahepatic lymphatic invasion (p = 0.02) were independent predictors of recurrence. The number of CLMs (p = 0.02) and prehepatectomy carcinoembryonic antigen level (p = 0.02), but not intrahepatic lymphatic invasion (p = 0.18), were independent predictors of survival using multivariate analysis. CONCLUSIONS The presence of intrahepatic lymphatic invasion adversely affected patient's DFS, but not OS in patients with CLMs in the era of FOLFOX/FIRI chemotherapy. FOLFOX/FIRI-based chemotherapy might improve OS, even in patients with positive intrahepatic lymphatic invasion.

Abstract
BACKGROUND This study investigates tumor recurrence patterns and their effect on postrecurrence survival following curative-intent treatment of colorectal liver metastases (CRLM) to identify those who stand to benefit the most from adjuvant liver-directed therapy. METHODS This is a retrospective analysis of all patients that underwent liver resection and/or ablation for CRLM between 2007 and 2019. Postrecurrence survival was compared between recurrence locations. Risk factors for liver recurrence were sought. RESULTS The study included 227 patients. Majority were treated with resection (71.0%) while combination resection/ablation (18.9%) and ablation alone (11.0%), were less common. At a median follow-up of 3.0 years, recurrence was observed in 151 (66.5%) patients. Of those, liver, lung, and peritoneal recurrence were most common at 66.9%, 49.6%, and 9.2%, respectively. Median postrecurrence survival after liver, lung, and multisite recurrence was 39.6-, 68.4-, and 33.6 months, respectively. High tumor grade (p < 0.014), perineural invasion (p = 0.002), and N0 node status (p = 0.017) of primary tumor correlated with liver recurrence on multivariate analysis. CONCLUSIONS Tumor grade, perineural invasion, and N0 node status of the primary tumor are associated with increased risk of liver recurrence after CRLM resection and represent a target population that may benefit the most from adjuvant liver-directed regional chemotherapy.

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.

Abstract
INTRODUCTION Resection is the mainstay of treatment for colorectal liver metastases (CRLMs). Many different histopathological factors related to the primary colorectal tumour have been well studied; however, histopathological prognostic factors related to CRLMs are still under evaluation. OBJECTIVE To identify histopathological factors related to overall survival (OS) and disease-free survival (DFS) in patients with resected CRLMs. METHODS A systematic review was performed with the following databases up to August 2020: PubMed, EMBASE, Web of Science, SciELO, and LILACS. The GRADE approach was used to rate the overall certainty of evidence by outcome. RESULTS Thirty-three studies including 4,641 patients were eligible. We found very low certainty evidence that the following histopathological prognostic factors are associated with a statistically significant decrease in OS: presence of portal vein invasion (HR, 0,50 [95% CI, 0,37 to 0,68]; I²=0%), presence of perineural invasion (HR, 0,55 [95% CI, 0,36 to 0,83]; I²=0%), absence of pseudocapsule (HR, 0,41 [CI 95%, 0,29 to 0,57], p<0,00001; I²=0%), presence of satellite nodules (OR, 0,45 [95% CI, 0,26 to 0,80]; I²=0%), and the absence of peritumoural inflammatory infiltrate (OR, 0,20 [95% CI, 0,08 to 0,54]; I²=0%). Outcome data on DFS were scarce, except for tumour borders, which did not present a significant impact, precluding the meta-analysis. CONCLUSION Of the histopathological prognostic factors studied, low- to moderate-certainty evidence shows that vascular invasion, perineural invasion, absence of pseudocapsule, presence of satellite nodules, and absence of peritumoral inflammatory infiltrate are associated with shorter overall survival in CRLMs.

Abstract
Background Gadoxetic acid (Gd-EOB-DTPA)-enhanced MRI is superior to CT in the detection of colorectal liver metastases (CRLMs) smaller than 10 mm. However, few studies have used MRI findings to predict patients' long-term prognosis. Purpose To investigate the relationship between Gd-EOB-DTPA-enhanced MRI findings in the liver parenchyma peripheral to CRLM and both pathologic vessel invasion and long-term prognosis. Materials and Methods This retrospective study included patients who underwent Gd-EOB-DTPA-enhanced MRI before curative surgery for CRLM, without neoadjuvant chemotherapy, between July 2008 and June 2015. Early enhancement, reduced Gd-EOB-DTPA uptake, and bile duct dilatation peripheral to the CRLM at MRI were evaluated by three abdominal radiologists. All tumor specimens were reevaluated for the presence or absence of portal vein, hepatic vein, and bile duct invasion. Predictors of recurrence-free survival (RFS) and overall survival (OS) after surgery were identified with Cox proportional hazard model with the Bayesian information criterion. Previously reported prognosticators were selected for multivariable analyses. The median follow-up period was 60 months (range, 9-127 months). Results Overall, 106 patients (mean age, 65 years ± 12 [standard deviation]; 68 men) with 148 CRLMs were evaluated. Bile duct dilatation peripheral to the tumor was associated with pathologic portal vein invasion (sensitivity, 12 of 50 [24%]; specificity, 89 of 98 [91%]; P = .02), bile duct invasion (sensitivity, eight of 19 [42%]; specificity, 116 of 129 [90%]; P = .001), poor RFS (P = .03; hazard ratio [HR] = 2.4 [95% confidence interval {CI}: 1.3, 4.2]), and poor OS (P = .01; HR = 2.4 [95% CI: 1.2, 4.9]). For RFS and OS, early enhancement and reduced Gd-EOB-DTPA uptake peripheral to the CRLM were eliminated by means of variable selection in the multivariable analysis, but the combination of these findings with bile duct dilatation provided a predictor of poor OS (P = .001; HR = 3.3 [95% CI: 1.6, 6.8]). Conclusion MRI signal intensity changes peripheral to the colorectal liver metastasis were predictors of long-term prognosis after curative surgery without neoadjuvant chemotherapy. © RSNA, 2020 Online supplemental material is available for this article.

Alabraba E, Ibrahim H, Olaru A, Cameron I, Gomez D, Group NHPBS. Retrospective cohort study of statin therapy effect on resected colorectal liver metastases. World J Gastrointest Surg 2020; 12:34-44. [PMID: 32128027 PMCID: PMC7044105 DOI: 10.4240/wjgs.v12.i2.34] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2019] [Revised: 11/24/2019] [Accepted: 12/15/2019] [Indexed: 02/06/2023] Open
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
BACKGROUND Perineural invasion is associated with adverse oncological outcomes in colorectal cancer. However, data regarding the prognostic and predictive impact in colon cancer are scarce. OBJECTIVE This study aims to clarify the role of perineural invasion in patients with nonmetastatic colon cancer. DESIGN This study is a retrospective review of a prospectively maintained database. SETTINGS This study took place at a tertiary medical center. PATIENTS Patients with stage I to III colon cancer who underwent elective surgery at our tertiary center between 2004 and 2015 (n = 1145) were included. MEAN OUTCOME MEASURES The primary long-term outcomes include disease-free survival, disease-specific survival, and overall survival. Differences were determined by multivariate Cox regression models adjusted for stage and potential confounders. RESULTS Perineural invasion was identified in 215 patients (18.8%) and associated with emergency procedures, male sex, and advanced disease. Histopathological features including lymphatic and extramural vascular invasion, poor differentiation, and infiltrating tumor borders were correlated with perineural invasion. Compared with patients with perineural invasion-negative tumors, patients who had perineural invasion-positive tumors had worse disease-free, overall, and disease-specific survival (all p < 0.001). Moreover, patients with perineural invasion-positive node-negative disease had worse overall survival than patients with perineural invasion-negative node-positive disease (p < 0.001). After adjustment, perineural invasion remained significantly associated with worse disease-free survival (HR, 1.45; 95% CI, 1.03-2.03; p = 0.033), worse overall survival (HR, 1.75; 95% CI, 1.33-2.31; p < 0.001), and worse disease-specific survival (HR, 1.52; 95% CI, 1.00-2.30; p = 0.048). However, we did not find a significant predictive response with adjuvant chemotherapy in perineural invasion-positive node-negative tumors (HR, 2.10; 95% CI, 0.80-5.51; p = 0.122). The predictive value was only demonstrated in stage III disease with a significant impaired overall survival in patients with perineural invasion-positive tumors who did not receive adjuvant therapy (HR, 0.23; 95% CI, 0.13-0.40; p < 0.001). LIMITATIONS This study was limited by its retrospective design. CONCLUSION Our study confirms the prognostic value of perineural invasion in stage I to II and III colon cancer. However, patients with node-negative disease and perineural invasion did not significantly benefit from adjuvant therapy. More information regarding postoperative treatment in node-negative perineural invasion-positive colon cancer is required. See Video Abstract at http://links.lww.com/DCR/A988. LA INVASIÓN PERINEURAL COMO FACTOR PRONÓSTICO NO PREDICTIVO EN EL CÁNCER DE COLON NO METASTÁSICO: La invasión perineural se encuentra asociada a resultados oncológicos adversos en casos de cáncer colorrectal. Sin embargo, los datos sobre el impacto pronóstico y predictivo en caso de cáncer de colon son pocos. OBJETIVO Definir el papel de la invasión perineural en pacientes con cáncer de colon no metastásico. DISEÑO:: Revisión retrospectiva de una base de datos alimentada prospectivamente. AJUSTES Centro hospitalario de atención terciaria. PACIENTES Todos aquellos portadores de un cáncer de colon estadío I-III que se sometieron a cirugía electiva en nuestro centro entre 2004-2015 (n = 1145). PRINCIPALES RESULTADOS Los resultados a largo plazo incluyeron la supervivencia sin enfermedad, la supervivencia específica de la enfermedad y la supervivencia general. Las diferencias se determinaron mediante modelos de regresión multivariantes de Cox, ajustados para el control de factores de confusión durante el análisis por estratificación. RESULTADOS La invasión perineural fué identificada en 215 pacientes (18.8%) y se la asoció con procedimientos de emergencia, al género masculino y a la enfermedad avanzada. Las características histopatológicas que incluyeron la invasión vascular linfática y extramural, la diferenciación deficiente y los bordes tumorales infiltrantes se correlacionaron con la invasión perineural. Comparativamente con los tumores sin invasión perineural, los pacientes positivos a la invasión perineural tuvieron una peor supervivencia general, libre y específica de la enfermedad (todos p < 0.001). Asimismo, aquellos pacientes con invasion-perineural con ganglios negativos tuvieron una supervivencia global mucho peor que aquellos pacientes con ganglios positivos e invasión perineural negativa (p < 0.001). Después del ajuste, la invasión perineural se asoció significativamente con una peor supervivencia sin la enfermedad (HR, 1.45; IC 95%, 1.03-2.03; p = 0.033), supervivencia general (HR, 1.75; IC 95%, 1.33-2.31; p <0.001), así como con una peor supervivencia específica de la enfermedad (HR, 1.52; IC 95%, 1.00-2.30; p = 0.048). Sin embargo, no encontramos una respuesta predictiva significativa con quimioterapia adyuvante en los tumores acompañados de invasion-perineural con ganglios negativos (HR, 2.10; IC del 95%, 0.80-5.51; p = 0.122). El valor predictivo solo fué demostrado en aquellos casos de estadio III con un deterioro significativo de la supervivencia global en pacientes con tumores perineurales positivos a la invasión y que no recibieron tratamiento adyuvante (HR, 0.23; IC 95%, 0.13-0.40; p < 0.001). LIMITACIONES Diseño retrospectivo. CONCLUSIÓN:: Nuestros resultados confirman el valor pronóstico de la invasión perineural en el cáncer de colon estadios I-II y III. Sin embargo, los pacientes con enfermedad ganglionar negativa e invasión perineural no se beneficiaron significativamente de la terapia adyuvante. Se requiere más información sobre el tratamiento postoperatorio en el cáncer de colon positivo para la invasión perineural con ganglios negativos.

Abstract
Colorectal carcinoma (CRC) is one of the most common malignancies and a major cause of cancer-related death worldwide. The liver is the most frequent site of metastatic spread, so that about half of the patients with CRC have or develop liver metastases (LM) during the clinical course of the disease. Colorectal LM can potentially be cured by surgery, but most patients still experience disease progression and recurrence after the surgical treatment. Prediction of a patient's post-surgical clinical course is mainly based on clinical parameters or the histopathological features of the primary tumor, while little attention is given to the pathological characteristics of the LM. In this paper, we review the prognostic relevance of the gross and microscopic pathological features observed in surgically resected LM and propose which information should be included in the histopathological report to guide surgeons and oncologists for the subsequent therapeutic management.

Abstract
Background and Aims: The impact of biliary invasion on recurrence and survival, after resection of colorectal cancer liver metastases, is not well known as publications are limited to small patient series. The aim was to investigate if biliary invasion in liver resected patients associated with liver relapses and recurrence-free survival. Secondary endpoints included association with other prognostic factors, disease-free survival and overall survival. Materials and Methods: All patients with histologically verified biliary invasion (n = 31, 9%) were identified among 344 patients with liver resection between January 2009 and March 2015. Controls (n = 78) were selected from the same time period and matched for, among others, size and number of colorectal cancer liver metastasis. Results: Median liver recurrence-free survival was significantly shorter in patients with biliary invasion than in controls (15.3 months versus not reached; p = 0.031) and more relapses were noted in the liver (61.3% versus 33.3%; p = 0.010), respectively. In univariate analyses for liver recurrence-free survival, biliary invasion was the only significant prognostic factor; p = 0.034. There were no statistical differences in disease-free and overall survival between the groups. Conclusion: Biliary invasion was associated with higher liver recurrence rates and shorter liver recurrence-free survival in patients with resected colorectal cancer liver metastasis.

Abstract
AIM To analyze the survival trends in colorectal cancer (CRC) based on the different classifications recommended by the seventh and eighth editions of the American Joint Committee on Cancer staging system (AJCC-7th and AJCC-8th).
METHODS The database from our institution was queried to identify patients with pathologically confirmed stage 0-IV CRC diagnosed between 2006 and 2012. Data from 2080 cases were collected and 1090 cases were evaluated through standardized inclusion and exclusion criteria. CRC was staged by AJCC-7th and then restaged by AJCC-8th. Five-year disease-free survival (DFS) and overall survival (OS) were compared. SPSS 21.0 software was used for all data. DFS and OS were compared and analyzed by Kaplan-Meier and Log-rank test.
RESULTS Linear regression and automatic linear regression showed lymph node positive functional equations by tumor-node-metastasis staging from AJCC-7th and tumor-node-metastasis staging from AJCC-8th. Neurological invasion, venous infiltration, lymphatic infiltration, and tumor deposition put forward stricter requirements for pathological examination in AJCC-8th compared to AJCC-7th. After re-analyzing our cohort with AJCC-8th, the percentage of stage IVB cases decreased from 2.8% to 0.8%. As a result 2% of the cases were classified under the new IVC staging. DFS and OS was significantly shorter (P = 0.012) in stage IVC patients compared to stage IVB patients.
CONCLUSION The addition of stage IVC in AJCC-8th has shown that peritoneal metastasis has a worse prognosis than distant organ metastasis in our institution’s CRC cohort. Additional datasets should be analyzed to confirm these findings.

The Prognostic Value of Varying Definitions of Positive Resection Margin in Patients with Colorectal Cancer Liver Metastases. J Gastrointest Surg 2018; 22:1350-1357. [PMID: 29633114 DOI: 10.1007/s11605-018-3748-3] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2018] [Accepted: 03/15/2018] [Indexed: 02/08/2023]
Abstract
BACKGROUND Varying definitions of resection margin clearance are currently employed among patients with colorectal cancer liver metastases (CRLM). Specifically, a microscopically positive margin (R1) has alternatively been equated with an involved margin (margin width = 0 mm) or a margin width < 1 mm. Consequently, patients with a margin width of 0-1 mm (sub-mm) are inconsistently classified in either the R0 or R1 categories, thus obscuring the prognostic implications of sub-mm margins. METHODS Six hundred thirty-three patients who underwent resection of CRLM were identified. Both R1 definitions were alternatively employed and multivariable analysis was used to determine the predictive power of each definition, as well as the prognostic implications of a sub-mm margin. RESULTS Five hundred thirty-nine (85.2%) patients had a margin width ≥ 1 mm, 42 had a sub-mm margin width, and 52 had an involved margin (0 mm). A margin width ≥ 1 mm was associated with improved survival vs. a sub-mm margin (65 vs. 36 months; P = 0.03) or an involved margin (65 vs. 33 months; P < 0.001). No significant difference in survival was detected between patients with involved vs. sub-mm margins (P = 0.31). A sub-mm margin and an involved margin were both independent predictors of worse OS (HR 1.66, 1.04-2.67; P = 0.04, and HR 2.14, 1.46-3.16; P < 0.001, respectively) in multivariable analysis. Importantly, after combining the two definitions, patients with either an involved margin or a sub-mm margin were associated with worse OS in multivariable analysis (HR 1.94, 1.41-2.65; P < 0.001). CONCLUSIONS Patients with involved or sub-mm margins demonstrated a similar inferior OS vs. patients with a margin width > 1 mm. Consequently, a uniform definition of R1 as a margin width < 1 mm should perhaps be employed by future studies.

Abstract
INTRODUCTION Hepatectomy including conversion therapy is recommended for colorectal liver metastasis (CRLM). CRLM complicated with bile duct tumor thrombus (BDTT) is rare, even though there are more opportunities to perform hepatectomy for CRLM in recent years. PRESENTATION OF CASE A 76-year-old Japanese man with a history of right hemicolectomy for ascending colon carcinoma presented with a portal hepatic tumor and the dilatation of the right bile duct found by computed tomography (CT) eighteen months after the colectomy. Magnetic resonance imaging confirmed a tumor in liver segment VIII, and magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography showed a mass in the hilar bile duct. Bile cytology did not prove carcinoma. The patient underwent right and caudate lobectomy with extrahepatic biliary tract resection plus hepaticojejunostomy. Histopathological examination revealed that both the tumor in liver segment VIII and the BDTT comprised moderately differentiated tubular adenocarcinoma, originating from the previous colon carcinoma. Six months after hepatectomy, CT revealed tumor recurrence in the residual intrahepatic bile duct. Radiation therapy was administered for the recurrent lesion, which reduced the tumor size temporarily. Despite the multimodal therapy, the disease progressed and the patient died one year after the hepatectomy. DISCUSSION Some studies reported no correlation between CRLM bile duct invasion and clinical outcomes, but there is no available evidence focused on BDTT which is of an advanced stage in the bile duct invasion. CONCLUSION Hepatectomy is a common therapeutic procedure for CRLM, but CRLM with BDTT might be associated with a bad prognosis.

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.

[PMID: 29203074 DOI: 10.1016/j.ejso.2017.11.018] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2017] [Revised: 10/21/2017] [Accepted: 11/19/2017] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND The value of microscopic biliary and perineural invasion as prognostic biomarkers in patients with resectable colorectal liver metastases (CLM) who undergo neoadjuvant chemotherapy and liver resection is still unclear. This retrospective study was performed to elucidate this issue. METHODS Histologic slides of resected CLM of patients who underwent neoadjuvant bevacizumab-based chemotherapy and liver resection were investigated with respect to biliary and perineural invasion. Presence of invasion was correlated with radiologic and histologic response, recurrence-free survival (RFS) and overall survival (OS). RESULTS One hundred forty-one patients were enrolled. There was a significant association between biliary and perineural invasion, respectively (P = 0.001). Moreover, both biliary and perineural invasion were associated with bilobar metastatic spread and higher number of metastases, while perineural invasion was also associated with a higher Fong score. No significant association was found with response. In univariable analysis, biliary and perineural invasion were associated with shorter RFS (median 10.1 vs. 13.5 months, HR 2.09, P = 0.010 and 7.6 vs. 14.0, HR 2.23, P = 0.001, respectively). Biliary invasion was also associated with shorter OS (median 32.8 months vs. not reached, HR 2.78, P = 0.010), however these results did not remain significant in multivariable analysis. CONCLUSIONS In patients with resectable colorectal liver metastases undergoing neoadjuvant bevacizumab-based chemotherapy and liver resection, biliary and perineural invasion are associated with higher tumor load but may not be prognostic biomarkers.

Abstract
BACKGROUND General population screening for colorectal cancer starts at 50, and incidence rates of rectal cancer in patients over 50 years old are decreasing. However, incidence of rectal cancer under age 50 is increasing. This paper analyzes short-and long-term outcomes for rectal cancer patients under 50 years of age. METHODS Retrospective analyses of consecutive patient cohort, who all received surgical treatment for primary rectal adenocarcinoma at a single institute were used in the study. Outcomes were stratified based on age under or over 50 at the time of surgery. RESULTS A total of 582 patients was included, of whom 125 were younger than 50. ASA-score was higher for older patients, with no other significant differences in baseline characteristics. AJCC-staging, based on surgical pathology, differed significantly due to higher stage II-rate in the older group and higher stages III- and IV-rates in the younger group. Percentages of high-grade disease, small vessel-, and perineural invasion were higher for younger patients. Stage-for-stage oncologic survival analyses did not demonstrate a significant difference between younger and older patients. Additionally, an age under/over 50 did not have a significant effect in multivariable analyses for disease free-, and disease specific survival. CONCLUSIONS Patients who present with rectal cancer under the age of 50 do not seem to have more aggressive disease, while they present with more advanced disease when compared to patients older than 50. Identifying young people at risk of developing rectal cancer and start screening earlier in a selective group might improve disease stage on presentation.

Abstract
Background Preoperative interventions have increased the resectability of colorectal cancer (CRC) liver metastases. This retrospective study compares outcomes after liver resection for bilobar CRC metastases between patients who underwent parenchyma-sparing hepatectomy (PSH), i.e., segmentectomies and smaller resections on both lobes, and those treated with non-PSH, i.e., hemihepatectomy plus any resection on the other lobe. Methods A cohort of 119 patients who underwent liver resection for bilobar CRC metastases were included. Perioperative course and long-term survival were compared between 59 patients who underwent PSH and 60 patients who underwent non-PSH. Statistical analyses were done using Pearson's chi-square test, Fisher's exact test and the Mann-Whitney U test. Overall survival analysis was performed by the Kaplan-Meier estimator and Cox regression analysis. Results The median number of liver metastases was 2 in patients treated with PSH and 3 in those treated with non-PSH (P<0.01). Postoperative mortality, severe complications and radicality did not differ significantly between groups. Median intraoperative bleeding was 250 mL for PSH and 600 mL for non-PSH (P<0.001). Median operation time and hospital stay were significantly shorter for PSH. Overall survival was comparable between groups, also after adjustment for covariates. Conclusions There were no significant differences in outcome, except for differences in bleeding, operation time and postoperative stay, favoring PSH. Furthermore, minimizing resection did not influence radicality. Hence, this study supports the use of PSH for bilobar CRC liver metastases when possible.

Abstract
BACKGROUND Fbxw7 is a tumor suppressor through ubiquitination and degradation of multiple oncoproteins. Loss of Fbxw7 is frequently observed in various human cancers. In this study, we examined the role of Fbxw7 expression in colorectal liver metastasis (CRLM) and its mechanism. METHODS Fifty-six patients with CRLM who undergo curative resection were enrolled. Fbxw7 in tumor tissue was determined by immunohistochemistry. Patients were divided into two groups, the Fbxw7 high and low groups. Clinicopathological factors including miR-223 expression were compared between the high (n = 32) and low Fbxw7 groups (n = 24). RESULTS Fbxw7 expression in tumor tissues was significantly lower than that in normal tissues. The disease-free survival in the low Fbxw7 group was significantly worse than that in the high Fbxw7 group, and 3 years disease-free survival of the low and high Fbxw7 groups were 12.5% and 47.0%, respectively (P = 0.023). On multivariate analysis, loss of Fbxw7 was detected as one of the independent risk factors for recurrence of CRLM (hazard ratio: 2.390, P = 0.017). Likewise, Fbxw7 expression inversely correlated to miR-223 expression (P = 0.017). CONCLUSION Loss of Fbxw7 in tumor tissues could be a reliable predictor of recurrence after hepatectomy in patients with CRLM, and miR-223 might be a possible regulator of Fbxw7.

Abstract
Colorectal cancer is a leading cause of death worldwide. The liver is the most common site of distant metastases, and surgery is the only potentially curative treatment, although the recurrence rate following surgery is high. In order to define prognosis after surgery, many histopathological features have been identified in the primary tumour. In turn, pathologists routinely report specific findings to guide oncologists on the decision to recommend adjuvant therapy. In general, the pathological report of resected colorectal liver metastases is limited to confirmation of the malignancy and details regarding the margin status. Most pathological reports of a liver resection for colorectal liver metastasis lack information on other important features that have been reported to be independent prognostic factors. We herein review the evidence to support a more detailed pathological report of the resected liver specimen, with attention to: the number and size of liver metastases; margin size; the presence of lymphatic, vascular, perineural and biliary invasion; mucinous pattern; tumour growth pattern; the presence of a tumour pseudocapsule; and the pathological response to neoadjuvant chemotherapy. In addition, we propose a new protocol for the evaluation of colorectal liver metastasis resection specimens.

Abstract
AIM To evaluate the outcome of patients with bilobar colorectal liver metastases (CRLM) and identify clinico-pathological variables that influenced survival.
METHODS Patients with bilobar CRLM were identified from a prospectively maintained hepatobiliary database during the study period (January 2010-June 2014). Collated data included demographics, primary tumour treatment, surgical data, histopathology analysis and clinical outcome. Down-staging therapy included Oxaliplatin- or Irinotecan- based regimens, and Cetuximab was also used in patients that were K-RAS wild-type. Response to neo-adjuvant therapy was assessed at the multi-disciplinary team meeting and considered for surgery if all macroscopic CRLM were resectable with a clear margin while preserving sufficient liver parenchyma.
RESULTS Of the 136 patients included, thirty-two (23.5%) patients were considered inoperable and referred for palliative chemotherapy, and thirty-four (25%) patients underwent liver resection. Seventy (51.4%) patients underwent down-staging therapy, of which 37 (52.8%) patients responded sufficiently to undergo liver resection. Patients that failed to respond to down-staging therapy (n = 33, 47.1%) were referred for palliative therapy. There was a significant difference in overall survival between the three groups (surgery vs down-staging therapy vs inoperable disease, P < 0.001). All patients that underwent hepatic resection, including patients that had down-staging therapy, had a significantly better overall survival compared to patients that were inoperable (P < 0.001). On univariate analysis, only resection margin significantly influenced disease-free survival (P = 0.017). On multi-variate analysis, R0 resection (P = 0.030) and female (P = 0.036) gender significantly influenced overall survival.
CONCLUSION Patients undergoing liver resection with bilobar CRLM have a significantly better survival outcome. R0 resection is associated with improved disease-free and overall survival in this patient group.

Abstract
OBJECTIVE To identify significant predictive factors for overall survival (OS) and disease-free survival (DFS) after liver resection for colon cancer metastases, with special focus on features of the primary colon cancer, such as lymph node ratio (LNR), vascular invasion, and perineural invasion. METHODS Patients operated for colonic cancer liver metastases between 2006 and 2014 were included. Details on patient characteristics, the primary colon cancer operation and metastatic disease were collected. Multivariate analysis was performed to select predictive variables for OS and DFS. RESULTS Median OS and DFS were 67 and 20 months, respectively. 1-, 3- and 5-year OS were 97, 76, and 52%. 1-, 3- and 5-year DFS were 65, 42, and 37%. Multivariate analysis showed LNR to be an independent predictive factor for DFS but not for OS. Other identified predictive factors were vascular and perineural invasion of the primary colon cancer, size of the largest metastasis and severe complications after liver surgery for OS, and perineural invasion, number of liver metastases and preoperative CEA-level for DFS. Traditional N-stage was also considered to be an independent predictive factor for DFS in a separate multivariate analysis. CONCLUSIONS LNR and perineural invasion of the primary colon cancer can be used as a prognostic variable for DFS after a concomitant liver resection for colon cancer metastases. Vascular and perineural invasion of the primary colon cancer are predictive for OS.
