Prognostic value of creatine kinase (CK)-MB to total-CK ratio in colorectal cancer patients after curative resection. BMC Cancer 2024; 24:543. [PMID: 38684978 PMCID: PMC11059638 DOI: 10.1186/s12885-024-12307-5] [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: 11/08/2023] [Accepted: 04/23/2024] [Indexed: 05/02/2024] Open
Abstract
OBJECTIVES This study aimed to evaluate the prognostic significance of postoperative Creatine Kinase type M and B (CK-MB) to total Creatine Kinase (CK) ratio (CK-MB/CK) in colorectal cancer (CRC) patients after radical resection. METHODS This was a single-center retrospective cohort analysis. Subjects were stage I-III CRC patients hospitalized in Sichuan Cancer Hospital from January 2017 to May 2021. Patients were divided into abnormal group and normal group according to whether the CK-MB/CK ratio was abnormal after surgery. Through a comparative analysis of clinical data, laboratory test results, and prognosis differences between the two groups, we aimed to uncover the potential relationship between abnormal CK-MB > CK results and CRC patients. To gauge the impact of CK-MB/CK on overall survival (OS) and disease-free survival (DFS), we employed the multivariable COX regression and LASSO regression analysis. Additionally, Spearman correlation analysis, logistic regression, and receiver-operating characteristic (ROC) curve analysis were conducted to assess the predictive value of the CK-MB/CK ratio for postoperative liver metastasis. RESULTS Cox regression analysis revealed that the CK-MB/CK ratio was a stable risk factors for OS (HR = 3.82, p < 0.001) and DFS (HR = 2.31, p < 0.001). To distinguish hepatic metastases after surgery, the ROC area under the curve of CK-MB/CK was 0.697 (p < 0.001), and the optimal cut-off value determined by the Youden index was 0.347. CONCLUSIONS Postoperative abnormal CK-MB/CK ratio predicts worse prognosis in CRC patients after radical resection and serves as a useful biomarker for detecting postoperative liver metastasis.

Less contrast, more clarity, innovative visualization technique for management of multiple colorectal liver metastases using microwave ablation through a portal venous access. Radiol Case Rep 2024; 19:1638-1641. [PMID: 38327554 PMCID: PMC10847831 DOI: 10.1016/j.radcr.2024.01.038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2023] [Revised: 01/11/2024] [Accepted: 01/16/2024] [Indexed: 02/09/2024] Open
Abstract
Colorectal cancer, a leading cause of cancer-related deaths, often results in liver metastases, with about half of patients affected. For those ineligibles for surgery, percutaneous microwave ablation (MWA) offers a viable alternative. Conventionally, visualizing liver lesions prior to MWA demands significant IV contrast, often needing repeated sessions. We introduce a technique using minimal IV contrast to treat multiple metastatic lesions simultaneously. A case of a 47-year-old male with stage 4 colorectal adenocarcinoma and multiple liver metastases is presented. Instead of the typical 100-150 cc of IV contrast, our method used just 25 cc, successfully ablating 6 hepatic metastases in 1 session. This approach not only reduces contrast volume but also optimizes treatment efficiency.

Multi-sequence MRI radiomics of colorectal liver metastases: Which features are reproducible across readers? Eur J Radiol 2024; 172:111346. [PMID: 38309217 DOI: 10.1016/j.ejrad.2024.111346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Revised: 01/15/2024] [Accepted: 01/25/2024] [Indexed: 02/05/2024]
Abstract
PURPOSE To assess the inter-reader reproducibility of radiomics features on multiple MRI sequences after segmentations of colorectal liver metastases (CRLM). METHOD 30 CRLM (in 23 patients) were manually delineated by three readers on MRI before the start of chemotherapy on the contrast enhanced T1-weighted images (CE-T1W) in the portal venous phase, T2-weighted images (T2W) and b800 diffusion weighted images (DWI). DWI delineations were copied to the ADC-maps. 107 radiomics features were extracted per sequence. The intraclass correlation coefficient (ICC) was calculated per feature. Features were considered reproducible if ICC > 0.9. RESULTS 90% of CE-T1W features were reproducible with a median ICC of 0.98 (range 0.76-1.00). 81% of DWI features were robust with median ICC = 0.97 (range 0.38-1.00). The T2W features had a median ICC of 0.96 (range 0.55-0.99) and were reproducible in 80%. ADC showed the lowest number of reproducible features with 58% and median ICC = 0.91 (range 0.38-0.99) When considering the lower bound of the ICC 95% confidence intervals, 58%, 66%, 54% and 29% reached 0.9 for the CE-T1W, DWI, T2W and ADC features, respectively. The feature class with the best reproducibility differed per sequence. CONCLUSIONS The majority of MRI radiomics features from CE-T1W, T2W, DWI and ADC in colorectal liver metastases were robust for segmentation variability between readers. The CE-T1W yielded slightly better reproducibility results compared to DWI and T2W. The ADC features seem more susceptible to reader differences compared to the other three sequences.

Ferroptosis induced by DCPS depletion diminishes hepatic metastasis in uveal melanoma. Biochem Pharmacol 2023; 213:115625.

Abstract
Hepatic metastasis develops in ∼50% of uveal melanoma (UM) patients with scarcely effective treatment resulting in lethality. The underlying mechanism of liver metastasis remains elusive. Ferroptosis, a cell death form characterized by lipid peroxide, in cancer cells may decrease metastatic colonization. In the present study, we hypothesized that decapping scavenger enzymes (DCPS) impact ferroptosis by regulating mRNA decay during the metastatic colonization of UM cells to liver. We found that inhibition of DCPS by shRNA or RG3039 induced gene transcript alteration and ferroptosis through reducing the mRNA turnover of GLRX. Ferroptosis induced by DCPS inhibition eliminates cancer stem-like cells in UM. Inhibition of DCPS hampered the growth and proliferation both in vitro and in vivo. Furthermore, targeting DCPS diminished hepatic metastasis of UM cells. These findings may shed light on the understanding of DCPS-mediated pre-mRNA metabolic pathway in UM by which disseminated cells gain enhanced malignant features to promote hepatic metastasis, providing a rational target for metastatic colonization in UM.

Tumor attachment to Major intrahepatic vascular for Colorectal liver metastases. BMC Surg 2023; 23:169. [PMID: 37353772 DOI: 10.1186/s12893-023-01971-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Accepted: 03/24/2023] [Indexed: 06/25/2023] Open
Abstract
BACKGROUND Colorectal liver metastases attached major intrahepatic vessels has been considered to be a risk factor for survival outcome after liver resection. The present study aimed to clarify the outcomes of R1 surgery (margin < 1 mm) in CRLM patients, distinguishing parenchymal margin R1 and attached to major intrahepatic vessels R1. METHODS In present study, 283 CRLM patients who were evaluated to be attached to major intrahepatic vessels initially and underwent liver resection following preoperative chemotherapy. They were assigned to two following groups: R0 (n = 167), R1 parenchymal (n = 58) and R1 vascular (n = 58). The survival outcomes and local recurrence rates were analyzed in each group. RESULTS Overall, 3- and 5-year overall survival rates after liver resection were 53.0% and 38.2% (median overall survival 37 months). Five-year overall survival was higher in patients with R0 than parenchymal R1 (44.9%% vs. 26.3%, p = 0.009), whereas there was no significant difference from patients with vascular R1 (34.3%, p = 0.752). In the multivariable analysis, preoperative chemotherapy > 4 cycles, clinical risk score 3-5, RAS mutation, parenchymal R1 and CA199 > 100 IU/ml were identified as independent predictive factors of overall survival (p < 0.05). There was no significant difference for local recurrence among three groups. CONCLUSION Parenchymal R1 resection was independent risk factor for CRLM. Vascular R1 surgery achieved survival outcomes equivalent to R0 resection. Non-anatomic liver resection for CRLM attached to intrahepatic vessels might be pursued to increase patient resectability by preoperative chemotherapy.

Abstract
BACKGROUND Microwave ablation (MWA) via ultrasound guidance is an important tool in the treatment of liver metastases. The most common postoperative complications are abdominal hemorrhage and bile leakage, whereas thrombosis in the suprahepatic inferior vena cava (IVC) is very rare, and clinical management is very difficult when the head end of the thrombus reaches the right atrium. CASE PRESENTATION This is a case report of a 52-year-old man with hepatic metastasis 21 months after radical resection of rectal cancer. After chemotherapy combined with targeted therapy, metastasis in segment IV (S4) of the liver was treated with microwave ablation. Two months after treatment, the hepatic metastasis in S4 showed a microwave ablation zone on MRI.Enhanced MRI showed venous thrombosis located in the left hepatic vein and IVC, and the head of the thrombus reached the right atrium. After two weeks of anticoagulation and thrombolytic treatment, the follow-up MRI showed that the venous thrombus had nearly disappeared. CONCLUSION When liver metastases are close to the hepatic vein, clinicians should pay attention to the occurrence of hepatic vein and IVC thrombosis following MWA; through early diagnosis and anticoagulation, pulmonary thromboembolism (PTE) can be minimized.

Abstract
Background Gastric cancer (GC) is one of the most common malignancies, and the liver is the most common site of hematogenous metastasis of GC. AMIGO2 is a type I transmembrane protein that has been implicated in tumour cell adhesion in adenocarcinomas; however, its importance in GC remains undetermined. Methods We analyzed AMIGO2 expression by immunohistochemistry using the specific monoclonal antibody for human AMIGO2 in 128 patients who underwent GC surgery to evaluate its relationship between various metastatic and clinical outcomes in GC. Results Immunohistochemistry revealed that AMIGO2 expression was an independent prognostic factor for overall survival, disease-specific survival, and liver metastasis in GC patients. Conclusions This study showed that AMIGO2 is induced in GC tissues and can mediate hepatic metastasis. Determining AMIGO2 expression in GC will help predict patient prognosis and the incidence of liver metastasis.

Abstract
BACKGROUND The impact of hepatic resection for liver metastases (LM) on the survival of pediatric patients with Wilms' tumor (WT) is unclear. So far, there is a lack of studies investigating the best suited treatment for patients with WTLM, and the role of liver resection has rarely been investigated. Thus, the development of evidence-based guidelines concerning indications of liver resection for WTLM remains difficult. AIM To investigate the role of surgery in the therapy of WTLM. All available data on liver resections and subgroup outcomes of patients with WTLM are analyzed. Main research question is whether liver resection improves survival rates of patients with WTLM compared to non-surgical treatment. METHODS A systematic literature search of MEDLINE, Web of Science, and Central provided the basis for this PRISMA-compliant systematic review. For the main analysis (I), all studies reporting on surgical treatment of pediatric WTLM were included. To provide a representative overview of the general outcome of WTLM patients, in analysis II all studies with cohorts of at least five WTLM patients, regardless of the kind of treatment, were reviewed and analyzed. A Multiple meta-regression model was applied to investigate the impact liver resection on overall survival. RESULTS 14 studies with reports of liver resection for WTLM were found (Analysis I). They included a total of 212 patients with WTLM, of which 93 underwent a liver resection. Most studies had a high risk of bias, and the quality was heterogenous. For the analysis II, eight studies with subgroups of at least five WTLM patients were found. The weighted mean overall survival (OS) of WTLM patients across the studies was 55% (SD 29). A higher rate of liver resection was a significant predictor of better OS in a multiple meta-regression model with 4 covariates (I2 29.43, coefficient 0.819, p = 0.038). CONCLUSIONS This is the first systematic review on WTLM. Given a lack of suited studies that specifically investigated WTLM, ecological bias was high in our analyses. Generating evidence is complicated in rare pediatric conditions and this study must be viewed in this context. Meta-regression analyses suggest that liver resection may improve survival of patients with WTLM compared to non-surgical treatment. Especially patients with persisting disease after neoadjuvant chemotherapy but also patients with metachronous LM seem to benefit from resection. Complete resection of LM is vital to achieve higher OS. Studies that prospectively investigate the impact of surgery on survival compared to non-surgical treatment for WTLM are highly needed to further close the current evidence gap.

Abstract
Background Perianal Paget’s disease (PPD) is a rare malignancy, often associated with an underlying adenocarcinoma and a poor prognosis. Case presentation A 69-year-old female was presented with a history of perianal pruritus for 6 months and enlarged inguinal lymph nodes in the left side. Paget cells were confirmed by pathology after a wide excision of perianal skin. Radiotherapy was performed covering the bilateral inguinal lymphatic drainage area. Hepatic metastasis was found 8 months after surgery. Hepatic artery embolization (HAE) and high-intensity focused ultrasound therapy (HIFU) were performed successively. However, hepatic metastasis happened again 3 months later. Ultrasound-guided percutaneous radiofrequency ablation (PRFA) was carried out and various means of inspection could not identify the primary tumor. In the case of rapid progression of the tumor, we gave the patient chemotherapy regimens of XELOX. After 4 cycles of chemotherapy, the tumor marker went down continuously and the hepatic metastasis stayed stable. Conclusions Hepatic metastasis from perianal Paget’s disease without identified underlying carcinoma may benefit from XELOX on the basis of adenocarcinoma.

Abstract
PURPOSE There are no established treatment strategies for patients with hepatic and pulmonary metastases at the time of primary colorectal cancer (CRC) diagnosis. This study assessed patients undergoing complete resection of primary CRC and hepatic and pulmonary metastases, to evaluate long-term outcomes and clarify clinicopathological factors associated with failure of complete resection. METHODS This retrospective analysis enrolled patients at Shizuoka Cancer Center between 2002 and 2018 who underwent colorectal resection with curative intent for primary CRC with hepatic and pulmonary metastases. The curative resection (CR) group comprised patients who underwent complete resection of the primary tumor and metastatic lesions, and the non-curative resection (Non-CR) group consisted of those in whom resection of the metastatic lesions was not performed. Univariate and multivariate analyses were conducted to determine clinicopathological factors associated with non-curative resection. RESULTS Of 26 total patients, the CR and Non-CR groups consisted of 14 (54%) and 12 patients (46%), respectively. In the CR group, the 3-year overall and relapse-free survival rates were 92.9% and 28.6%, respectively. Multivariate analysis showed that pathological stage T4 (odds ratio 8.58, 95% confidence interval 1.13-65.20, p = 0.04) was independently associated with non-curative resection. CONCLUSION The percentage of patients undergoing complete resection of primary CRC and metastatic lesions was 56%, and the 3-year OS rate was 92.9%. Resection of primary CRC and metastatic lesions was considered to be appropriate in this population, and pathological stage T4 tumor was associated with incomplete resection of metastatic tumors.

Abstract
BACKGROUND AND AIMS Hepatic tuberculosis (HTB) is rare and mimics neoplastic liver lesions clinico-radiologically leading to misdiagnosis and even unnecessary surgery. METHODS AND MATERIAL We analysed 43 cases of HTB diagnosed at a referral cancer centre over 10 years. Clinical details, investigations and treatment received were noted. RESULTS The median age was 46 years with a female preponderance (58%). HTB was diagnosed incidentally in 28% cases during surveillance imaging for a previous cancer. Constitutional symptoms (31, 72%), abdominal pain (25, 58%), fever (12, 28%), hepatomegaly (22, 51%), elevated alkaline phosphatase (34, 79%), elevated aminotransferases (18, 42%) and hypoalbuminemia (19, 45%) were common features. All cases had negative HIV serology and normal tumor markers. Twenty-two (52.5%) had solitary liver lesion and lesions > 2 cm in 28 (65%). Ultrasound showed hypoechoic lesions in 31 of 33 cases. Computed tomography showed hypodense lesions (43,100%) with mild peripheral enhancement (32, 74%). Calcifications (5, 12%) and capsular retraction (8, 19%) was uncommon. MRI was performed in seven cases commonly showed T1 hypointense, T2 hyperintense lesions with restricted diffusion. Histopathology showed granulomatous inflammation (42, 97.5%), Langhan's giant cells (41, 95%) and caseation necrosis (35, 85%). Acid-fast stain and PCR positivity was uncommon. Extrahepatic organs were involved in 20 (46.5%). HTB mimicked cholangiocarcinoma (25, 58%), liver metastasis (11, 26%) and lymphoma (3, 7%). Six patients underwent liver resection with a presumptive diagnosis of cancer without a preoperative biopsy. All patients received antitubercular therapy, 37 had clinico-radiological response, there were 3 deaths and 3 patients were lost to follow-up. CONCLUSION HTB is rare and can mimic a malignancy clinico-radiologically. Calcifications and pseudocapsule appearance on multiphase CT scan may help in differentiating HTB from hepatic malignancy. Tumor markers are normal while histopathology is generally diagnostic. A high index of suspicion is required to avoid unnecessary surgery as the patients respond well to ATT. TRIAL REGISTRATION This is a retrospective and observational study hence clinical trial registration is not applicable.

A rare case of hepatic metastasis 20 years after surgical resection of a thymoma: A case report. Int J Surg Case Rep 2021; 87:106406.

Abstract
INTRODUCTION Thymoma is the most common solid, primary mediastinal tumour, accounting for 20% of mediastinal neoplasms. Malignant thymus tumours (thymomas and thymic carcinomas) metastasize primarily locally. Distant metastases, especially to liver are very rare. PRESENTATION OF CASE We review the case of a 59 year-old female patient, who underwent resection of the thymus with a diagnosed type B2 thymoma 20 years ago. The patient was referred to our hospital with a newly discovered space-occupying lesion in the liver, which had been detected in a routine follow-up magnetic resonance imaging scan. Since a malignant tumour of the liver could not be excluded, a conventional left hemihepatectomy was performed. Histological examination revealed a liver metastasis of the type B2 thymoma, which had been removed 20 years ago. CLINICAL DISCUSSION The case was discussed in the interdisciplinary tumour board. Based on the very long history of the primary removal of the thymoma as well as the R0 resection of the liver metastasis, a follow-up regimen with CT scans on a regular basis was recommended. CONCLUSIONS Newly discovered lesions of the liver in patients even with a long history of a thymoma should raise the suspicion of a liver metastasis that should be surgically resected as the therapy of choice. Further, this case indicates the importance for long-term radiographic follow-up.

Abstract
A primary splenic angiosarcoma is a rare type of soft tissue sarcoma and is associated with an extremely poor prognosis. In this study, we describe the case of a patient who was diagnosed with metastatic primary splenic angiosarcoma and survived for about 2 years. A 62-year-old female was referred to us for the treatment of splenic angiosarcoma with disseminated intravascular coagulation (DIC) and multiple liver and bone metastases. Paclitaxel therapy resulted in recovery from DIC and enabled her to continue sequential treatment through to sixth-line chemotherapy. We reviewed all splenic angiosarcoma case reports which were described as stage IV to date and compared with our case. From these data, we found that the median overall survival was 105 days, and the prognosis of splenic angiosarcoma of stage IV was worse than conventional case series. Splenectomy was performed in more patients than chemotherapy as a treatment. Moreover, various chemotherapeutic regimens were used. These data suggest that administering chemotherapy including paclitaxel to patients with splenic angiosarcoma might improve their prognosis.

Abstract
The liver is one of the most common sites of metastatic spread of lung cancer, and the process of metastasis is regulated by many factors. A number of genes, including multiple tumor suppressor 1 (mts1), p120 catenin, and CT45A1, increase the possibility of hepatic metastasis in lung cancer, whereas Tip30/CC3, CUL5, and SOCS3 expression in lung tumors inhibit tumor metastasis. microRNAs (miRNAs), such as miRNA-126, miRNA-338, and miRNA-218, can affect the metastasis of lung cancer cells to the liver. The D114-Notch signaling pathway can inhibit liver metastasis in small cell lung cancer. Serum tumor markers cytokeratin 19 fragment antigen 21-1 and neuron-specific enolase (NSE) are closely related to the risk of hepatic metastasis in lung cancer. Based on previously published literature, we found that the metastasis and invasion of lung cancer to the liver are determined by molecular factors. Therefore, the selective identification and intervention of these erroneous signals can predict early lung cancer metastasis to the liver. In this review article, we describe the mechanisms and influencing factors (genes, signal pathways, chemicals, proteins, miRNAs) of hepatic metastasis in lung cancer. We hope to provide a summary of the evidence for the mechanisms by which related genes or proteins affect the malignancy of liver metastasis from lung cancer so that doctors and researchers can improve treatment options.

MEDICAL SCIENCE EDITION 2021; 52:311-318. [PMID: 33829708 PMCID: PMC10408915 DOI: 10.12182/20210360202] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Indexed: 02/05/2023]
Abstract
OBEJECTIVE To explore the clinical value of using radiomics models based on different MRI sequences in the assessment of hepatic metastasis of rectal cancer. METHODS 140 patients with pathologically confirm edrectal cancer were included in the study. They underwent baseline magnetic resonance imaging (MRI) between April 2015 and May 2018 before receiving any treatment. According to the results of liver biopsy, surgical pathology, and imaging, patients were put into two groups, the patients with hepatic metastasis and those without. T2 weighted images (T2WI), diffusion weighted images (DWI) and apparent diffusion coefficient (ADC) images were used to draw the region of interest (ROI) of primary lesions on consecutive slices on ITK-SNAP. 3-D ROIs were generated and loaded into Artificial Intelligent Kit for extraction of radiomics features and 396 features were extracted for each sequence. The feature data were preprocessed on Python and the samples were oversampled, using Support Vector Machine-Synthetic Minority Over-Sampling Technique (SVM-SMOTE) to balance the number of samples in the group with liver metastasis and the group with no liver metastasis at the end of the follow-up. Then, the samples were divided into the training cohort and the test cohort at a ratio of 2∶1. The logistic regression models were developed with selected radionomic features on R software. The receiver operating characteristics (ROC) curves and calibration curves were used to evaluate the performance of the models. RESULTS In total, 52 patients with liver metastasis and 88 patients without liver metastasis at the end of follow-up were enrolled. Carcinoembryonic antigen (CEA) and T stage and N stage evaluated on the MRI images showed statistically significant difference between the two groups ( P<0.05). After data preprocessing and selecting, except for 17 non-radiomic features, the model combining T2WI, DWI and ADC features, the model of T2WI features alone, the model of DWI features alone and the model of ADC features alone were developed with 32 features, 10 features, 30 features and 15 features, respectively. The combined model (T2WI+DWI+ADC), the T2WI model, and the ADC model can assess hepatic metastasis accurately, with the area under curve ( AUC) on the train set reaching 93.5%, 89.2%, 90.6% and that of the test set reaching 80.8%, 80.5%, 81.4%, respectively. The combined model did not show a higher AUC than those of the T2WI and ADC alone models. Model based on DWI features has a slightly insufficient AUC of 90.3% in the train set and 75.1% in the test set. The calibration curve showed the smallest fluctuation in the combined model, which is closest fit to the diagonal reference line. The fluctuation in the three independent data set models were similar. The calibration curves of all the four models showed that as the risk increased, the prediction of the models turned from an underestimation to an overestimating the risk. In brief, the combined model showed the best performance, with the best fit to the diagonal reference line in calibration curve and high AUC comparable to the AUC of the T2WI model and ADC model. The performance of T2WI and ADC alone models were second to that of the combined model, while the DWI alone model showed relatively poor performance. CONCLUSION Radiomics models based on MRI could be effectively used in assessing liver metastasis in rectal cancer, which may help determine clinical staging and treatment.

Integrated genomic and transcriptomic analysis reveals unique characteristics of hepatic metastases and pro-metastatic role of complement C1q in pancreatic ductal adenocarcinoma. Genome Biol 2021; 22:4. [PMID: 33397441 PMCID: PMC7780398 DOI: 10.1186/s13059-020-02222-w] [Citation(s) in RCA: 27] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Accepted: 12/07/2020] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers due to its high metastasis rate in the liver. However, little is known about the molecular features of hepatic metastases due to difficulty in obtaining fresh tissues and low tumor cellularity. RESULTS We conduct exome sequencing and RNA sequencing for synchronous surgically resected primary tumors and the paired hepatic metastases from 17 hepatic oligometastatic pancreatic ductal adenocarcinoma and validate our findings in specimens from 35 of such cases. The comprehensive analysis of somatic mutations, copy number alterations, and gene expressions show high similarity between primary tumors and hepatic metastases. However, hepatic metastases also show unique characteristics, such as a higher degree of 3p21.1 loss, stronger abilities of proliferation, downregulation of epithelial to mesenchymal transition activity, and metabolic rewiring. More interesting, altered tumor microenvironments are observed in hepatic metastases, especially a higher proportion of tumor infiltrating M2 macrophage and upregulation of complement cascade. Further experiments demonstrate that expression of C1q increases in primary tumors and hepatic metastases, C1q is mainly produced by M2 macrophage, and C1q promotes migration and invasion of PDAC cells. CONCLUSION Taken together, we find potential factors that contribute to different stages of PDAC metastasis. Our study broadens the understanding of molecular mechanisms driving PDAC metastasis.

ULTRASOUND IN MEDICINE & BIOLOGY 2020; 46:2254-2264. [PMID: 32546409 DOI: 10.1016/j.ultrasmedbio.2020.05.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/29/2020] [Revised: 03/25/2020] [Accepted: 05/04/2020] [Indexed: 06/11/2023]
Abstract
This study evaluated the feasibility of contrast vector imaging (CVI) to characterize focal liver lesions. From July to October 2019, we prospectively enrolled 30 patients with focal liver lesions (hepatocellular carcinoma [HCC] [n = 19], metastasis [n = 8], combined HCC-cholangiocarcinoma [CC] [n = 1], intra-hepatic CC [n = 1] and sclerosed hemangioma [n = 1]). Contrast-enhanced ultrasound (CEUS) was performed with high frame rate contrast harmonic imaging technique by one radiologist, and post-processing CVI was obtained and analyzed by two radiologists. On combined CVI with CEUS, the staining pattern was significantly predominant in HCCs (9/11, 81.8%), while peripheral rim was frequent in non-HCCs (5/8, 62.5%) (p = 0.020). HCCs exhibited feeding arteries (8/11, 45.5%) and high velocity variance (10/11, 90.9 %), whereas non-HCCs showed detour pattern (4/8, 50.0%) with either a high or low velocity variance (4/8, 50.0%, both), with no significant inter-group differences (p = 0.052 and 0.080, respectively). In conclusion, CVI was feasible and provided quantitative and multi-parametric information of different types of hepatic tumors.

Abstract
Background Tuberculosis (TB) is classified according to the site of disease as pulmonary or extrapulmonary. Extrapulmonary TB is less common than its counterpart in which it can be found anywhere in the body including the liver. Similar to ampullary carcinoma, TB liver can manifest with jaundice and deranged liver function tests, particularly in the obstructed biliary systems. Case presentation A 43-year-old gentleman with locally advanced ampullary carcinoma was noticed to have multiple suspicious liver nodules intraoperatively during curative ampulla resection. The surgery was then abandoned after a biopsy. The histology was consistent with chronic granulomatous inflammation. He was then subjected to a Whipple pancreaticoduodenectomy procedure after initiation of anti-tubercular treatment. He recovered well with no evidence of tumour recurrence and worsening TB. Conclusions A high index of suspicion and quick decision making can help to diagnose a possible extrapulmonary TB masquerading as a malignant disease in a patient with curative intention of ampullary carcinoma.

Abstract
PURPOSE We analysed our initial experience with SBRT in liver metastasis from colorectal cancer at our institution. MATERIALS AND METHODS Between January/2014 and December/2017, 22 patients with 31 LMCCR were treated. Local control (LC) was assessed using the Kaplan-Meier and log-rank tests. We analysed potential prognostic factors for LC: sex, PTV size, number of LM and the radiation scheme. RESULTS Median age: 69 years. Prior chemotherapy or local liver treatments: 81.8% and 63.6% of patients, respectively. SBRT consisted of 3 × 20 Gy (42.9%) and 3 × 15 Gy (31.4%). There were 88.5% responses (57.1% CR and 31.4% PR). Median follow-up was 30 months. LC per lesion at 12 and 24 months was 85.3% and 61.8%, respectively. Tumour volumes > 30 cc correlated with worsened 2-year-control rates (90% vs 34.5%) (p = 0.005). There was only a patient with CTC-grade 3 toxicity. CONCLUSIONS Liver SBRT is a safe and effective treatment that achieves high local control rates. We found a significant correlation between larger LMCRC and worse local control.

Abstract
This is a borderline tumor with indolent biological behavior. There are still multiple poorly understood factors that can dictate its malignant transformation and prognosis. Here, a rare tumor whose age and survival are tangent the literature reports describe. There is a need for a long and rigorous segment to identify possible long-term metastases.
Introduction Frantz’s Tumor or Solid Pseudopapillary Neoplasm (SPN) is rare with a solid-cystic pattern, and most common in young women. Presentation of case This study based on guidelines for case reports (SCARE) reports a case of SPN in a teenager aged 13 years at the diagnosis time, attended at a teaching public hospital in Brazil, which evolved into liver metastases. Clinical, laboratory, therapeutic and imaging data were collected from the physical chart and analyzed in light of current publications on the topic. The first consultation occurred in January 2012, where weight loss, fever, vomiting, left-sided hypochondrium and epigastric pain were reported. Imaging exams evidenced an expansive heterogeneous process in the pancreatic tail; however, laboratory exams and tumor markers did not present alteration in relation to reference values. In March of 2012, she underwent caudal body pancreatectomy, splenectomy, segmental colectomy and colo-coloanastomosis as a function of the intraoperative findings. After 63 months, right-sided hepatectomy was performed to resect metastases. Currently, she is undergoing outpatient monitoring, without complaint or alterations in imaging and laboratory exams, totaling 100 months of global survival. Discussion This is an interesting case report of a rare tumor, in so far as without any adjuvant chemotherapies, an 8-year long survival time could be achieved in this particular type of tumor despite initially large tumor expansion and later liver metastases. Conclusion Additional epidemiological studies, molecular and clinical trials are required to increase knowledge on SPN.

Abstract
A 73-year-old man presented with multiple liver nodules on an abdominal echogram. Fluorine-18-fluorodeoxyglucose (FDG)-positron emission tomography computed tomography (PET-CT) showed multiple nodules in his anterior and posterior mediastinum, and liver. Following thymothymectomy with lymph node dissection, the liver nodules were completely resected. Finally, he was diagnosed with combined thymic tumor (small cell carcinoma and type B3 thymoma) with multiple mediastinal lymph nodes and liver metastases by type B3 thymoma. Follow-up PET-CT scan revealed multiple rib and celiac lymph node metastases, six courses of chemotherapy (paclitaxel and carboplatin) were administered, and the patient survived without any recurrence for 15 years after initial surgery.

Abstract
BACKGROUND Hepatic metastasis develops in ~ 50% of uveal melanoma (UM) patients with no effective treatments. Although GNAQ/GNA11 mutations are believed to confer pathogenesis of UM, the underlying mechanism of liver metastasis remains poorly understood. Given that profound epigenetic evolution may occur in the long journey of circulating tumor cells (CTCs) to distant organs, we hypothesized that EZH2 endowed tumor cells with enhanced malignant features (e.g., stemness and motility) during hepatic metastasis in UM. We aimed to test this hypothesis and explore whether EZH2 was a therapeutic target for hepatic metastatic UM patients. METHODS Expression of EZH2 in UM was detected by qRT-PCR, Western blotting and immunohistochemistry staining. Proliferation, apoptosis, cancer stem-like cells (CSCs) properties, migration and invasion were evaluated under circumstances of treatment with either EZH2 shRNA or EZH2 inhibitor GSK126. Antitumor activity and frequency of CSCs were determined by xenografted and PDX models with NOD/SCID mice. Hepatic metastasis was evaluated with NOG mice. RESULTS We found that EZH2 overexpressed in UM promoted the growth of UM; EZH2 increased the percentage and self-renewal of CSCs by miR-29c-DVL2-β-catenin signaling; EZH2 facilitates migration and invasion of UM cells via RhoGDIγ-Rac1 axis. Targeting EZH2 either by genetics or small molecule inhibitor GSK126 decreased CSCs and motility and abrogated the liver metastasis of UM. CONCLUSIONS These findings validate EZH2 as a druggable target in metastatic UM patients, and may shed light on the understanding and interfering the complicated metastatic process.

Abstract
BACKGROUND Retinoblastoma binding protein 4 (RBBP4) plays an essential role in the development of multiple cancers. However, its relationship with prognosis in colon cancer and colon cancer hepatic metastasis has not been elucidated. The aim of this study was to explore the relationship between RBBP4 expression and prognosis of colon cancer patients and to evaluate RBBP4 as a new prognostic marker in these patients. METHODS Eighty colon cancer patients underwent surgical resection of the colon were enrolled. Among them, forty colon cancer patients suffered with hepatic metastasis. The colon cancer tissues, para-colon cancer tissues, and hepatic metastatic cancer tissues were collected from the pathological department for further analysis. The expression of RBBP4 proteins was examined by immunohistochemistry and correlated with clinicopathological parameters. The Cancer Genome Atlas (TCGA) database was used to validate the expression and explore its relationship with clinical characteristics. RESULTS RBBP4 was up-regulated in the colon cancer tissues compared with the para-colon cancer tissues. The analysis of TCGA database verified the upregulation of RBBP4 in the colon cancer tissues and RBBP4 overexpression was correlated with nerve invasion and poor outcomes of chemotherapy. Moreover, the positive rate of RBBP4 expression in 40 colon cancer patients with hepatic metastasis was higher in the hepatic metastatic cancer tissues (39/40, 97.5%) than in the colon cancer tissues (26/40, 65.0%). Our clinicopathological analysis showed that RBBP4 expression was significantly correlated with vascular invasion, hepatic metastasis, and lymph node involvement (all P < 0.05). Additionally, the survival analysis demonstrated that RBBP4 over-expression was correlated with poor prognosis. CONCLUSIONS RBBP4 was upregulated in the colon cancer. RBBP4 may be a novel predictor for poor prognosis of colon cancer and colon cancer hepatic metastasis.

Abstract
BACKGROUND Several case series reported results of surgical resection in patients with pancreatic ductal adenocarcinoma in a metastasized stage. AIM A summarized overview of the current state of knowledge and a summary of the results of currently available studies. MATERIAL AND METHODS A systematic search was carried out in MEDLINE and PubMed with respect to metastasized pancreatic cancer and surgical resection. RESULTS The evidence level for surgical resection in the metastasized stage is weak and so far no prospective trials are available. The largest single-arm trial included 85 patients with hepatic metastasis. In cases of hepatic oligometastasis an overall survival of 11-14 months was observed. In the presence of pulmonary metastasis, overall survival seems to be prolonged compared to intra-abdominal metastasis, although the evidence level is relatively weak. CONCLUSION According to the available results, a general recommendation for surgical resection in a metastasized stage cannot be given; however, the results show a possible benefit for some well-selected patient subgroups. Prospective trials must validate these data and investigate the use of combined surgical and systemic treatments in the case of resectable metastatic pancreatic cancer.

Abstract
Background The technique for arterial infusion chemotherapy (HAIC) is not standardized which limits its widely application. The aim of this study was to evaluate the long-term functionality and complications of port-catheter system using percutaneous unilateral trans-femoral implantation with coil only fixed-catheter-tip method. Methods From January 2013 to January 2017, 205 consecutive patients (138 men; aged 28–88 years; mean, 59.1 ± 11.2 years) with unresectable malignant liver tumors underwent percutaneous implantation of side-hole infusion port-catheter into hepatic artery using coil only fixed-catheter-tip method via the unilateral femoral artery. Technical success, procedure time, duration of port functionality, and complications of port dysfunction were investigated. Results Implantation technical success was 98.5% and the procedure time was 59.1 ± 10.2 min. Predictable functionality of the port-catheter system at 6-, 12-, and 24 months were 97.5, 89.9, 70.5%, respectively. Complications of port irreversible dysfunction were hepatic artery obstruction (4.0%), catheter occlusion (3.5%), and catheter dislocation (0.5%). Median 5 HAIC cycles (range: 1–14 cycles) were received via port. Conclusion Percutaneous unilateral trans-femoral implantation of a side-hole port-catheter with coils only fixed-catheter-tip method is a simple and feasible interventional technique for HAIC which offers long-term functionality.

Abstract
BACKGROUND Previous studies using the NSQIP database to study hepatectomies lacked hepatic specific variables and outcomes. We used the targeted NSQIP hepatectomy database to examine the nationwide trend and the safety profile of synchronous liver and colorectal resection compared with hepatectomy alone for colorectal liver metastasis. METHODS The targeted NSQIP hepatectomy database from 2014 was used to study patients who underwent hepatectomy for diagnosis of adenocarcinoma of the colon and rectum. RESULTS Of the 3064 hepatic resections in the database, 1138 cases were performed for colorectal metastasis. Of these, 1040 were liver-alone surgery and 98 were synchronous liver and colorectal resection. Most (58.7%) patients received neoadjuvant therapy. The rate of neoadjuvant therapy, intraoperative ablation, biliary reconstruction, and the use of minimally invasive technique were similar between the two groups. The overall 30-d mortality in this cohort was low (1.1%). While the mortality rate in the synchronous group was similar to liver-only group (3.1% versus 0.9%, P = 0.077). The rate of liver failure (3.3% versus 4.1%, P = 0.722) and biliary leak (5.3% versus 9.6%, P = 0.084) were similar between the two groups. However, the rate of major complications was higher on multivariable analyses (25.5% versus 12.1%, OR 2.5, 95% CI 1.5-4.1, P < 0.001) for the synchronous group. CONCLUSIONS Hepatic resection for colorectal metastasis in the modern era has low short-term mortality. While synchronous resection was associated with a higher incidence of major complications, liver-specific complications did not increase with synchronous resection.

Abstract
Objective: To investigate the ultrasonographic features of synchronous and heterochronic liver metastasis in patients with stromal tumors, and to elucidate the value of ultrasonic examination in follow-up surgery. Methods: A total of 1 516 patients with pathologically confirmed gastrointestinal stromal tumors (GISTs) and extra-gastrointestinal stromal tumors (EGISTs) were enrolled. The ultrasonographic features of primary lesions and liver metastases in a total of 46 cases with 95 liver metastases were analyzed. Results: 24 out of 46 cases had primary lesion in the small intestine, 14 in the stomach, 4 in the abdominal cavity, 1 in the colon, 2 in the esophagus, and 1 in the mesentery. The expression of CD117, Dog-1 and CD34were detected by immunohistochemical staining. The positive rate of CD117 was 100%, the Dog-1 was 95.7% and the CD34 was 69.6%. There were statistically significant differences in the maximum diameter, boundary and blood flow of primary tumors in 28 patients with synchronous liver metastasis and 18 patients with heterochronic liver metastasis (P=0.001, 0.022 and 0.036, respectively). Of the 95 liver metastases, 86 (90.5%) were located in the right lobe of the liver, 79 (83.2%) had clear boundaries, 75 (78.9%) were hypoechoic or isoechoic, 55 (57.9%) showed colored patterns, and 68 (71.6%) had no halo.11 liver metastases were cystic masses, 59 were solid masses, and 25 were mixed masses. There was a statistically significant difference in blood flow between 65 synchronous hepatic metastases and 30 heterochronic liver metastases (P=0.017). Conclusions: There were differences of the primary tumor ultrasonographic features between the synchronous metastasis group and heterochronic metastasis group. The ultrasonographic features of primary tumors and liver metastases have important clinical significance for the diagnosis, follow-up and treatment of malignant mesenchymal tumors.

Effect of primary tumor side on survival outcomes in metastatic colorectal cancer patients after hepatic arterial infusion chemotherapy. World J Gastrointest Oncol 2018; 10:431-438. [PMID: 30487954 PMCID: PMC6247101 DOI: 10.4251/wjgo.v10.i11.431] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2018] [Revised: 09/19/2018] [Accepted: 10/12/2018] [Indexed: 02/05/2023] Open
Abstract
AIM To analyze the survival data between patients diagnosed with right-sided primary (RSP) tumors and patients diagnosed with left-sided primary (LSP) tumors after hepatic arterial infusion chemotherapy (HAIC) at our center.
METHODS A retrospective analysis of pretreated metastatic colorectal cancer patients who received HAIC from May 2006 to August 2015 was conducted. A Cox proportional hazard regression analysis was used to assess the long-term survival outcomes. The mean and median age of patients was 61 years (range 27-85 years). There were 115 males and 53 females in our study.
RESULTS One hundred sixty-eight patients were enrolled in this study. The overall response rate was 28.9% in LSP patients and 27.3% in RSP patients. The disease control rate was 76.3% in LSP patients and 69.7% in RSP patients. The median overall survival in response to HAIC was 16.3 mo in the LSP arm and 9.3 mo in the RSP arm (P = 0.164). The median progression-free survival was 5.7 mo in the LSP arm and 4.2 mo in the RSP arm (P = 0.851).
CONCLUSION There was no significant difference in survival between LSP patients and RSP patients after HAIC. Further prospective studies are needed to confirm these findings.

Abstract
Leiomyosarcoma of an artery is very rare, and cases with hepatic metastasis are even rarer. We describe a case of a 70-year-old man who after follow up due to rectal cancer, presented with an intra-abdominal hypervascular mass and a hepatic mass. After surgical resection, it was diagnosed as a leiomyosarcoma of the right gastroepiploic artery with hepatic metastasis. Multiple metastases had recurred at the liver. He has survived more than 53 mo through multimodal treatments (three surgical resections, radiofrequency ablation, transarterial chemoembolization, chemotherapies, and targeted therapy). Multimodal treatments, including active surgical resection, may be helpful in the treatment of aggressive diseases such as arterial leiomyosarcoma with metastasis.

Emerging evidence of the molecular landscape specific for hematogenous metastasis from gastric cancer. World J Gastrointest Oncol 2018; 10:124-136.

Abstract
Gastric cancer (GC) is one of the most frequently diagnosed cancers in the world. Most GC patients are diagnosed when the cancer is in an advanced stage, and consequently, some develop metastatic lesions that generally cause cancer-related death. Metastasis establishment is affected by various conditions, such as tumor location, hemodynamics and organotropism. While digestive cancers may share a primary site, certain cases develop hematogenous metastasis with the absence of peritoneal metastasis, and vice versa. Numerous studies have revealed the clinicopathological risk factors for hematogenous metastasis from GC, such as vascular invasion, advanced age, differentiation, Borrmann type 1 or 2 and expansive growth. Recently, molecular mechanisms that contribute to metastatic site determination have been elucidated by advanced molecular biological techniques. Investigating the molecules that specifically participate in metastasis establishment in distinct secondary organs will lead to the development of novel biomarkers for patient stratification according to their metastatic risk and strategies for preventing and treating distinct metastases. We reviewed articles related to the molecular landscape of hematogenous metastasis from GC.

Abstract
The purpose of the study was to investigate the clinical factors influencing the prognosis of patients submitted to hepatectomy for metastases from gastric cancer and their clinical role. We conducted a retrospective multicentre review. We evaluated how survival from surgery was influenced by patient-related, tumour-related and treatment-related prognostic factors. We analysed data on 144 patients submitted to hepatectomy for metastases from gastric cancer, in the synchronous and metachronous setting. In 117 cases, an R0 resection was achieved, while in 27 an R + hepatic resection was performed. Chemotherapy was administered to 55 patients. Surgical mortality was 2.1% and morbidity 21.5%. One-, 3-, and 5-year OS rates after surgery were 49.9, 19.4 and 11.6%, respectively, with a median OS of 12.0 months. T4 gastric cancer, H3 hepatic involvement, non-curative resection, recurrence after surgery, and abstention from chemotherapy were associated with a worse prognosis. Factor T and H displayed a clear (p < 0.001) cumulative effect. Our data show that R0 resection must be pursued whenever possible. The treatment of T4 gastric cancer with hepatic bilateral and diffuse metastasis (H3) should be considered carefully or it should be probably avoided. Finally, a multimodal treatment associating surgery and chemotherapy offers the best survival results.

Abstract
Pseudocirrhosis is a rare hepatic complication of chemotherapy, which is morphological changes in hepatic contour that closely mimic cirrhosis. Like in classic cirrhosis, portal hypertension is common in patients with this condition. The mechanism of pseudocirrhosis is unknown to date. We report three cases of pseudocirrhosis arising in the setting of regression of breast cancer liver metastases. All the cases underwent systemic chemotherapy, and all had remarkable responses. Their hormone receptor statuses were all positive and Her2/neu statuses were all negative. They were all treated with cytotoxic chemotherapeutic agent and also hormone therapy. This report suggests clinicians should have pseudocirrhosis in mind when hormone therapy and cytotoxic chemotherapy are jointly administered.

Abstract
The liver is a major target organ for metastasis of both gastrointestinal and extra-gastrointestinal cancers. Due to its frequently inoperable nature, liver metastasis represents a leading cause of cancer-associated death worldwide. In the past years, the pivotal role of the immune system in this process is being increasingly recognised. In particular, the role of the hepatic macrophages, both recruited monocyte-derived macrophages (Mo-Mfs) and tissue-resident Kupffer cells (KCs), has been shown to be more versatile than initially imagined. However, the lack of tools to easily distinguish between these two macrophage populations has hampered the assignment of particular functionalities to specific hepatic macrophage subsets. In this Review, we highlight the most remarkable findings regarding the origin and functions of hepatic macrophage populations, and we provide a detailed description of their distinct roles in the different phases of the liver metastatic process.

Clinical relevance of oncologic prognostic factors in the decision-making of pre-hepatectomy chemotherapy for colorectal cancer hepatic metastasis: the priority of hepatectomy. World J Surg Oncol 2018; 16:24. [PMID: 29415722 PMCID: PMC5804072 DOI: 10.1186/s12957-018-1322-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2017] [Accepted: 01/23/2018] [Indexed: 02/06/2023] Open
Abstract
Background Although liver resection (LR) provides the best chance of long-term survival for patients with colorectal cancer (CRC) hepatic metastasis, concerns regarding chemotherapy before liver resection remain unresolved. Methods A retrospective review of patients who underwent curative LR for CRC hepatic metastasis between January 2008 and February 2016 was performed. Outcome relevance based on oncologic prognostic factors and chemotherapy prior to liver resection was assessed. Results Patients who had received pre-hepatectomy chemotherapy for CRC hepatic metastasis and delayed liver resection had a worse outcome in terms of CRC recurrence following liver resection. The hazard ratio (HR) of pre-hepatectomy chemotherapy in patients with minor oncologic prognostic factors was 1.55 (confidence interval, CI = 1.07–2.26, p = 0.021) for CRC recurrence after liver resection for hepatic metastasis, whereas the HR of pre-hepatectomy chemotherapy was 1.34 (CI = 0.99–1.81, p = 0.062) for CRC recurrence in patients with multiple oncologic prognostic factors. Conclusion The administration of pre-hepatectomy chemotherapy and delaying liver resection seems not to be an optimal strategy to provide a clinical benefit for patients with CRC hepatic metastasis. Hence, liver resection should be attempted without delay at the initial detection of CRC hepatic metastasis whenever possible.

Abstract
Objective To evaluate the effectiveness, safety, and feasibility of intraoperative radiofrequency ablation (IORFA) under ultrasound guidance for the treatment of liver metastases from gastrointestinal stromal tumors (GISTs). Materials and Methods From August 2009 to February 2017, 24 patients with liver metastases of GISTs underwent IORFA, 14 underwent concurrent IORFA and primary GIST resection, and 10 underwent IORFA to treat hepatic recurrence after previous primary GIST resection. Seventy-six hepatic metastases were treated, of which 47 were surgically resected and 29 underwent IORFA. All included patients received imatinib therapy as standard treatment before and after IORFA or surgical resection. A retrospective medical record review was conducted, and follow-up data were collected. Technical success and effectiveness, overall and GIST-specific survival, and complications were assessed. Results The mean follow-up duration was 50.7 ± 34.7 months. The technical success rate of IORFA was 100%. New metastases developed in three of the 24 patients (12.5%) following a complete response 16, 51, and 95 months after IORFA, respectively. The cumulative one-, three-, and five-year overall survival rates were 100, 94.4, and 87.7%, respectively. The one-, three-, and five-year GIST-related survival rates were 100, 94.4, and 94.4%, respectively. Two major complications (biliary stricture and hepatic abscess) were observed. Conclusion IORFA appears to be a feasible and safe treatment option for liver metastasis in patients with primary GISTs. In addition, IORFA and surgical resection may be complementary, helping to obtain complete response in cases of otherwise inoperable liver metastases secondary to GISTs.

Pneumoperitoneum after Endoscopic Retrograde Cholangiopancreatography due to Rupture of Intrahepatic Bile Ducts and Glisson's Capsule in Hepatic Metastasis: A Case Report and Review of Literature. Case Rep Gastroenterol 2017; 11:603-609.

Abstract
Introduction Endoscopic retrograde cholangiopancreatography (ERCP) has been proven to be a safe and effective method for diagnosis and treatment of biliary and pancreatic disorders. Major complications of ERCP include pancreatitis, hemorrhage, cholangitis, and duodenal perforation. We report a third case in literature of pneumoperitoneum after ERCP due to rupture of intrahepatic bile ducts and Glisson's capsule in a peripheral hepatic lesion. Case Report A 50-year-old male with a history of metastatic pancreatic neuroendocrine tumor and who had a partially covered metallic stent placed in the biliary tree 1 year ago presented to the oncology clinic with fatigue, abdominal pain, and hypotension. He was planned for ERCP for possible cholangitis secondary to obstructed previously placed biliary stent. However, the duodenoscope could not be advanced to the level of the major papilla because of narrowed pylorus and severely strictured duodenal sweep. Forward-view gastroscope was then passed with careful manipulation to the severely narrowed second part of the duodenum where the previously placed metallic stent was visualized. Balloon sweeping of stenting was done. Cholangiography did not show any leak. Following the procedure, the patient underwent CT scan of the abdomen that showed pneumoperitoneum which was communicating with pneumobilia through a loculated air collection in necrotic hepatic metastasis perforating Glisson's capsule. The patient was managed conservatively. Conclusion In our case, pneumoperitoneum resulted from rupture of intrahepatic bile ducts and Glisson's capsule in hepatic metastasis. This case emphasizes the need for close clinical and radiological observation of patients with hepatic masses (primary or metastatic) subjected to ERCP.

Abstract
The liver is the most common site of metastasis in patients with colorectal cancer due to
its anatomical situation regarding its portal circulation. About 14 to 18% of patients
with colorectal cancer present metastasis at the first medical consultation, and 10 to 25%
at the time of the resection of the primary colorectal cancer. The incidence is higher
(35%) when a computed tomography (CT) scan is used. In the last decades, a significant increase in the life expectancy of patients with
colorectal cancer has been achieved with different diagnostic and treatment programs.
Despite these improvements, the presence of metastasis, disease recurrence, and advanced
local tumors continue to remain poor prognostic factors. Median survival without treatment is <8 months from the moment of its presentation,
and a survival rate at 5 years of 11% is the best prognosis for those who present with
local metastasis. Even in patients with limited metastatic disease, 5-year survival is
exceptional. Patients with hepatic metastasis of colorectal cancer have a median survival
of 5 to 20 months with no treatment. Approximately 20 to 30% of patients with colorectal
metastasis have disease confined to the liver, and this can be managed with surgery.
Modern surgical strategies at the main hepatobiliary centers have proved that hepatectomy
of 70% of the liver can be performed, with a mortality rate of <5%. It is very important to have knowledge of predisposing factors, diagnostic methods, and
treatment of hepatic metastasis. However, the establishment of newer, efficient,
preventive screening programs for early diagnosis and adequate treatment is vital. How to cite this article: Valderrama-Treviño AI, Barrera-Mera B,

Abstract
Uterine leiomyosarcoma is an uncommon pathology, predominantly found in aged population. Patients with metastatic disease have poor survival and therapy mainly consists of palliative systemic chemotherapy. However, more aggressive strategies such as radiofrequency ablation (RFA) may benefit patients with limited secondary disease. RFA is considered a simple and safe modality for treatment of hepatic lesions. The benefits related to RFA include low morbidity, short hospital stay and the possibility to repeat the procedure when necessary due to recurrences. However, minor and major complications related to mechanical and thermal damage may occur, especially in cases of tumors adjacent to extrahepatic organs and those at subcapsular position. This case report shows a successful RFA of two hepatic subcapsular leiomyosarcoma metastases neighbouring the gallbladder, without a safe cleavage plane from it. Combined hydrodissection, percutaneous cholecystostomy and continuous irrigation were performed as effective techniques to prevent thermal injury. Clinical and radiological follow up demonstrates no local complication.

Abstract
The cytoplasmic polyadenylation element binding protein 4 (CPEB4) is a RNA binding protein and translational regulator. It has been associated with tumor growth, vascularization and invasion and with tumor progression in breast, pancreas and lung carcinomas. To the best of our knowledge only one previous report has analyzed the prognostic value of CPEB4 in an experimental model of colorectal carcinoma. We have reviewed the files of patients with stage IV colorectal carcinoma metastatic to the liver. All the patients had received chemotherapy followed by hepatic metastasis resection and subsequent resection of the colon (liver-first approach). We have gathered demographic, analytical and morphological data of the primary tumors. We have performed immunohistochemical analysis of CPEB4 expression in these tumors and analyzed the potential prognostic value of this protein. 50 patients fulfilled inclusion criteria for the present study. All of them received preoperative chemotherapy based on platinum and also postoperative chemotherapy, with or without targeted drugs (18% received anti-epidermal growth factor receptor (EGFR) drugs and 24% anti-vascular endothelial growth factor receptor (VEGFR) drugs. 66% of the primaries were of sigmoid-rectal origin. CPEB4 expression was mainly cytoplasmic and it was scored as intense in 46% of the patients. Survival analysis revealed a significant association between progression free survival (PFS) and overall survival (OS) and CPEB4 immunohistochemical expression, which was independent in the multivariate analysis. CPEB4 behaves as a significant predictor of prognosis in stage IV colorectal carcinoma. The existence of CPEB4 specific inhibitors can open a new way for targeted therapy. Larger prospective studies are needed to confirm our promising results.

Abstract
OBJECTIVES To obtain specific imaging findings of solitary necrotic nodule of the liver (SNNL) using longer delayed contrast-enhanced MRI and compare them with those of three mimic hepatic diseases. METHODS Sixteen patients with SNNL underwent plain and contrast-enhanced triphasic CT and multiphasic MRI with delayed time prolonged to 2 h after contrast bolus injection. Twenty-three patients with mimic lesions including seven with eight HCCs, five with five iCCs and 11 with metastatic lesions served as the control group. Those patients also received plain and multiphasic contrast-enhanced MRI. Imaging features of lesions such as peripheral wash-out time were evaluated. RESULTS Among the 16 SNNLs, with a prolonged delayed MRI time, the enhancement degree of tumour periphery increased gradually. When it was up to 1 h, all lesions represented moderate/marked peripheral enhancement with internal hypointensity. However, the peripheral wash-out in seven HCCs (87.5%) and all metastatic lesions except three appeared at 10 or 15 min, one iCC (20%) at 30 min and the other lesions at 1 h. CONCLUSIONS Longer MRI with a delayed time of 1-2 h may be useful in diagnosis SNNL, revealing the specific imaging characteristic of SNNL as pronounced peripheral enhancement with internal hypointensity. KEY POINTS • Longer delayed MRI plays an important role in the diagnosis of SNNL. • Characteristic imaging feature of SNNL is pronounced peripheral enhancement with internal hypointensity. • Periphery wash-out time can differentiate SNNL from mimic diseases. • Imaging findings of SNNL on routine CT and MRI are unspecific.

Abstract
The prognosis of a colon cancer with hepatic and ovarian metastasis is very poor. A colon cancer patient with hepatic and ovarian metastases can heal. In the literature we have never found a similar case. An appropriate surgical approach, a tailored chemotherapy and an intensive follow-up are essential. The degree to which HIPEC may have had an impact is still unknown.
Background In the international literature we have never found a long survival in patients treated for a colon cancer with synchronous hepatic metastases and for a metachronous Krukenberg tumor. Presentation of case A 46-year old woman for an advanced colon cancer with a synchronous hepatic metastases was subjected to a left hemicolectomy and a resection of liver segment V (R0 resection; T4N2bM1; stage IVa according AJCC 2010). After one year a CT of the abdomen revealed an expansive formation of the left ovary. The patient was subjected to a bilateral ovariectomy, hysterectomy and hiperthermic intraperitoneal chemotherapy (HIPEC). The patient, after several cycles of adjuvant chemotherapy, is disease-free 13 years after surgery. Discussion To our knowledge, in the literature there do not appear to be cases of such disease-free survival. The survival of patient despite the prognostic indexes is discussed. The authors discus the importance of an adequate surgical treatment especially for liver metastases simultaneously treated to colon cancer. The authors also focus on chemotherapy (FOLFOX and then FOLFIRI) performed in a pre-biological era. Furthermore, the degree to which the HIPEC may have had an impact is still unknown, although it seems to be the gold standard for the treatment of the microscopic peritoneal neoplastic remnant. Conclusion The authors emphasize that the long term survival in colon cancer with hepatic and ovarian metastases is possible as long as it has an adequate surgical approach, a tailored chemotherapy and an intensive follow-up. Most likely new prognostic markers will have to be identified.

Abstract
Worldwide, prostate cancer is considered the second most common cancer in men. Most common sites for metastatic disease are lymph nodes and bones. However, isolated liver metastasis from prostate cancer is rare. We present a 75 year-old male with prostate adenocarcinoma diagnosed 7 years ago. With rising PSA, he underwent imaging and found to have isolated hepatic metastasis. After left hepatic lobectomy, his PSA dramatically decreased to < 0.01. Physicians should be aware of isolated hepatic metastasis in patients with prostate cancer. Metastasectomy should be considered in such case, and combined medical and surgical approach may prolong the overall survival.

Abstract
Bleeding resulting from spontaneous rupture of the liver is an infrequent but potentially life threatening complication that may be associated with an underlying liver disease. A hepatocellular carcinoma or hepatic adenoma is frequently reported is such cases. However, hemoperitoneum resulting from a hepatic metastatic thymoma is extremely rare. Here, we present a case of a 62-year-old man with hypovolemic shock induced by ruptured hepatic metastasis from a thymoma. At the first hospital admission, the patient had a 45-mm anterior mediastinal mass that was eventually diagnosed as a type A thymoma. The mass was excised, and the patient was disease-free for 6 years. He experienced sudden-onset right upper quadrant pain and was again admitted to our hospital. We noted large hemoperitoneum with a 10-cm encapsulated mass in S5/8 and a 2.3-cm nodular lesion in the right upper quadrant of the abdomen. He was diagnosed with hepatic metastasis from the thymoma, and he underwent chemotherapy and surgical excision.

Abstract
Much has been written about hepatic metastasis and animal models abound. In terms of the human experience, progress in treating this final common pathway, a terminal event of many human malignancies has been relatively slow. The current thinking is that primary prevention is best served by early detection of cancer and eradication of early stage cancers by screening. Some cancers spread early in their course and the role of screening may be limited. Until relatively recently there has not been a pathfinder model that makes the evasion of this unfortunate event a reality. This review discusses such an animal model and attempts to relate it to human disease in terms of intervention. Concrete proposals are also offered on how scientists may be able to intervene to prevent this deadly progression of the cancer process.
