Construction and validation of "WCH-nomogram" for predicting the prognosis after resection of colorectal liver metastases. Cancer Med 2024; 13:e7222. [PMID: 38698687 PMCID: PMC11066479 DOI: 10.1002/cam4.7222] [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: 08/04/2023] [Revised: 03/18/2024] [Accepted: 04/14/2024] [Indexed: 05/05/2024] Open
Abstract
BACKGROUND The prognostic predictive tool for patients with colorectal liver metastasis (CRLM) is limited and the criteria for administering preoperative neoadjuvant chemotherapy in CRLM patients remain controversial. METHODS This study enrolled 532 CRLM patients at West China Hospital (WCH) from January 2009 to December 2019. Prognostic factors were identified from the training cohort to construct a WCH-nomogram and evaluating accuracy in the validation cohort. Receiver operating characteristic (ROC) curve analysis was used to compare the prediction accuracy with other existing prediction tools. RESULTS From the analysis of the training cohort, four independent prognostic risk factors, namely tumor marker score, KRAS mutation, primary lymph node metastasis, and tumor burden score were identified on which a WCH-nomogram was constructed. The C-index of the two cohorts were 0.674 (95% CI: 0.634-0.713) and 0.655 (95% CI: 0.586-0.723), respectively, which was better than the previously reported predication scores (CRS, m-CS and GAME score). ROC curves showed AUCs for predicting 1-, 3-, and 5-year overall survival (OS) of 0.758, 0.709, and 0.717 in the training cohort, and 0.860, 0.669, and 0.692 in the validation cohort, respectively. A cutoff value of 114.5 points was obtained for the WCH-nomogram total score based on the maximum Youden index of the ROC curve of 5-year OS. Risk stratification showed significantly better prognosis in the low-risk group, however, the high-risk group was more likely to benefit from neoadjuvant chemotherapy. CONCLUSIONS The WCH-nomogram demonstrates superior prognostic stratification compared to prior scoring systems, effectively identifying CRLM patients who may benefit the most from neoadjuvant chemotherapy.

Colorectal cancer treatment guidelines and shared decision making quality and reporting assessment: Systematic review. PATIENT EDUCATION AND COUNSELING 2023; 115:107856. [PMID: 37451055 DOI: 10.1016/j.pec.2023.107856] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Revised: 06/07/2023] [Accepted: 06/14/2023] [Indexed: 07/18/2023]
Abstract
INTRODUCTION Physicians must share decisions and choose personalised treatments regarding patients´ beliefs and values. OBJECTIVE To analyse the quality of the recommendations about shared decision making (SDM) in colorectal (CRC) and anal cancer treatment clinical practice guidelines (CPGs) and consensus statements (CSs). METHODS Guidelines were systematically reviewed following prospective registration (Prospero: CRD42021286146) without language restrictions searching 15 databases and 59 professional society websites from January 2010 to November 2021. A validated 31-item SDM quality assessment tool was employed to extract data in duplicate. RESULTS We identified 134 guidelines. Only 46/134 (34.3 %) mentioned SDM. Fifteen (11.1 %) made clear, precise and actionable recommendations, while 9/134 (6.7 %) indicated the strength of the SDM-related recommendations. CPGs underpinned by systematic reviews reported SDM more often than those based on consensus or reviews (35.9 % vs 32.0 %; p = 0.031). Guidelines that reported following quality tools (i.e., AGREE II) more commonly commented about SDM than when it was not reported (75.0 % vs 32.0 %; p = 0.003). CONCLUSION AND PRACTICE IMPLICATIONS Most of the CRC and anal treatment guidelines did not mention SDM and it was superficial. Guidelines based on systematic reviews and those using quality tools demonstrated better reporting of SDM. Recommendations about SDM in these guidelines merit urgent improvement.

Abstract
Objective: Liver metastasis is one of the prognostic factors of colorectal cancer (CRC). The aim of this study is to identify biomarkers that facilitate easier detection of liver metastasis. Methods: Significance Analysis of Microarrays (SAM) and Array Data Analyzer (ADA) were applied used for the analysis of differentially differently expressed mRNAs. mRNA expression was verified by quantitative real-timer reverse transcriptiontase polymerase chain reaction (qRT-PCR). Immunohistochemistry were was used to show natural killer-tumor recognition (NKTR) expression in CRC. NKTR-knockdown CRC cells were constructed obtained by using short hairpin RNA (shRNA). Followed by CCK-8 assay, plate colony formation test, and transwell assay were used to evaluate the influence of NKTR on cell proliferation, migration, and invasion in vitro. Results: SAM yielded showed 256 up-regulated and 224 down-regulated differentially differently expressed genes. Seven genes were identified by using ADA, tools and four genes were verified by using qRT-PCR. Three genes (metastasis associated lung adenocarcinoma transcript 1 (MALAT1), nuclear factor I/B (NKTR), and nuclear factor I/B (NFIB)) showed a statistically significant considerabley difference between CRC with and liver metastasis and CRC without liver metastasis. Immunohistochemical analysis showed that NKTR expression was much lower in primary CRC with liver metastasis than that in primary CRC without liver metastasis. The NKTR protein plays a role in the lytic function of natural killer (NK) cells and it has been rarely studied in the CRC. The down-regulation of NKTR by shRNA interference in CRC cells increased cell proliferation, migration, and invasion in vitro.

[PMID: 35903708 PMCID: PMC9315101 DOI: 10.3389/fonc.2022.916455] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2022] [Accepted: 06/06/2022] [Indexed: 12/04/2022] Open
Abstract
Purpose The aim of this study is to investigate the value of total laparoscopic simultaneous colorectal and hepatic resection in patients with synchronous colorectal cancer liver metastases (sCRLMs). Methods sCRLM patients who underwent simultaneous resection from December 2014 to December 2018 in Shanghai Cancer Center, Fudan University were recruited and analyzed retrospectively. The patients were divided into laparoscopic, open, and hybrid surgery groups. The intraoperative information, postoperative short-term outcome, and long-term survival were compared among the three groups. Propensity score matching (PSM) was performed to balance baselines. Results A total of 281 patients were recruited. After PSM, 34 patients were selected from both the laparoscopic and the open surgery group. Forty-seven patients were also selected from both the laparoscopic and the hybrid surgery group. The clinicopathologic baselines between the laparoscopic surgery group and the other two groups were well matched. All the operation-related indicators between laparoscopic surgery and hybrid surgery were similar. However, compared with open surgery, laparoscopic surgery showed significantly longer operation time (229.09 ± 10.94 min vs. 192.24 ± 9.49 min, p = 0.013) and less intraoperative blood loss [100.00 (50.00–300.00) ml vs. 200.00 (150.00–400.00) ml, p = 0.021]. For postoperative morbidity, there was no significant difference between the laparoscopic surgery group and the hybrid or the open surgery group (23.40% vs. 31.91% and 17.65% vs. 26.47%, p = 0.356 and p = 0.380). Long-term survival analysis showed that there were no significant differences in all 1-, 3-, and 5-year overall survival, liver recurrence-free survival (RFS), and whole RFS between laparoscopic surgery and hybrid surgery (p = 0.334, p = 0.286, and p = 0.558) or open surgery (p = 0.230, p = 0.348, and p = 0.450). Conclusions Laparoscopic simultaneous resection for sCRLM shows slight advantages in surgical safety and short-term outcome, and does not compromise long-term survival.

Induction Chemotherapy Followed by Primary Tumor Resection Did Not Bring Survival Benefits in Colon Cancer Patients With Asymptomatic Primary Lesion and Synchronous Unresectable Metastases. Front Oncol 2022; 12:747124. [PMID: 35174078 PMCID: PMC8841852 DOI: 10.3389/fonc.2022.747124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2021] [Accepted: 01/04/2022] [Indexed: 12/24/2022] Open
Abstract
BackgroundIt is still controversial whether primary tumor resection (PTR) improves survival in colorectal cancer (CRC) patients with unresectable metastases.MethodsColon cancer patients were enrolled and randomly allocated to with or without PTR after induction chemotherapy with XELOX or mFOLFOX6, and those with chemotherapy failure were excluded. The primary endpoint was TTF (time to strategy failure) on an intent-to-treat basis. This study is registered with ClinicalTrials.gov, number NCT02291744.ResultsBetween April 2015 and July 2020, 140 patients were enrolled, and 54 patients were excluded due to colon obstruction (16), perforation (1), disease progression (22), death (1), radical resection (3), or other reasons (11). After induction chemotherapy, 86 patients were randomized into group A (the resection group, n = 42) or group B (chemotherapy-alone group, n = 44). The median TTF was 143 days (95% CI: 104.9–181.1) in group A and 196 days (95% CI: 96.5–295.5) in group B (HR: 0.930 95% CI: 0.589–1.468, p = 0.755), and there was no significant difference in PFS, OS, and incidence of chemotherapy-related adverse events between two groups. The primary lesion-related events after PTR in group A were significantly fewer than those in group B. Patients with a tumor regression grade (TRG) score of 2 had longer TTF and PFS than those with score of 3.ConclusionPTR after induction chemotherapy could not bring survival benefits for colon cancer patients with unresectable metastases, and it is not recommended routinely. However, it also requires individualized treatment as colon obstruction or perforation occurred in some patients and PTR could reduce primary tumor-related events, and the TRG score might help for selection of beneficial patients.

Abstract
PURPOSE This study is a retrospective analysis of exploring the efficiency of surgical management on patients with synchronous colorectal liver metastasis (SCLM). PATIENTS AND METHODS Nine hundred fifty-three consecutive patients with SCLM from Weifang People's Hospital of Shandong Province between January 2006 and December 2015 were reviewed. The values of different factors were analyzed, such as different surgical indications of liver metastases, simultaneous or staged resection of primary colorectal cancer and liver metastases, and primary tumor resection (PTR) of asymptomatic patients with unresectable liver metastases. RESULTS Median survival time (47.3 months) and 5-year survival rate (31%) for patients with resected liver metastases were significantly superior to that of with nonoperative treatment (17.2 months, 4%, P<0.001); enlarging the standard of liver metastases resection can improve the resection rates (31.0% vs 13.6%, P<0.001); for patients with resectable liver metastases, the in-hospital cost for simultaneous resection group was lower than that in the staged resection group (36,698 vs 45,134 RMB, P<0.001); for patients of the asymptomatic primary tumor with unresectable liver metastases, PTR was associated with improved median survival (18.0 vs 15.0 months, P=0.006). CONCLUSION For patients with SCLM, liver resection is considered the best treatment; expanding indications of liver resection can improve the resection rates. Simultaneous resection of the primary tumor and liver metastases were indicated in patients with resectable SCLM; PTR was recommended for asymptomatic patients with unresectable hepatic metastases.

Abstract
Accumulating evidence has revealed that long noncoding RNAs (lncRNAs) play essential roles in regulating cellular process of various cancers. There have been many studies on the biological functions of lncRNAs in colorectal cancer (CRC). In this research, we explored the role and mechanism of lncRNA ovarian tumor domain containing 6B antisense RNA1 (OTUD6B-AS1) in CRC. Here, we detected OTUD6B-AS1 expression in CRC tissues and cells by RT-qPCR. Functional experiments were performed to test alterations in different cellular processes. Moreover, to verify the binding ability among the indicated RNA molecules, we carried out RIP, RNA pull-down and luciferase reporter assays. According to our data, OTUD6B-AS1 expression was low in CRC tissues and cells. Functionally, overexpression of OTUD6B-AS1 inhibited cell proliferation, migration, invasion and EMT, and promoted cell apoptosis. Bioinformatic analysis and mechanistical experiments confirmed that OTUD6B-AS1 could act as a competitive endogenous RNA (ceRNA) to upregulate Proline-Rich Nuclear Receptor Coactivator 2 (PNRC2) expression by sequestering miR-21-5p. Further rescue experiments validated the inhibitory function of the OTUD6B-AS1/miR-21-5p/PNRC2 axis in cellular process of CRC. Overall, OTUD6B-AS1 inhibits cellular development in CRC by sponging miR-21-5p and upregulating PNRC2, providing a novel insight into the exploration on CRC treatment.

Methods In total 62 colorectal cancer patient tissues and human CRC cell lines (OUMS23, SW116, SW480 and LOVO) were obtained for this study. SiLINC01116, miR-9-5p mimic, LINC01116, oe-STMN1 and their controls were transfected. The qRT-PCR method and Western blot were used to detect the levels of LINC01116, miR-9-5p and STMN1 in tissues and cells. CCK8 assay and flow cytometry were processed for proliferation and apoptosis, respectively. Transwell assay was undertaken to verify invasion and migration. Luciferase assay and pull down assay were processed to confirm the binding relationship among LINC01116, miR-9-5p and STMN1. Immunohistochemistry assay also detected the expression of STMN1. Kaplan–Meier survival curve was used to analyze patient survival rate. Pearson correlation analysis was used to evaluate the regulatory relationship between LINC01116, miR-9-5p and STMN1 in tissues. Results LINC01116 was expressed higher in CRC tissues and cells. Patients with higher expression of LINC01116 had worse prognosis. Knockdown of LINC01116 suppressed development of CRC cell. LINC01116 negatively regulated miR-9-5p, while MiR-9-5p was negatively related to STMN1. miR-9-5p mimic could rescue the effect of LINC01116, inhibit migration and invasion, and improve apoptosis of CRC cells. Oe-STMN1 could also rescue the effect of miR-9-5p on the development of colorectal cancer. Conclusion LINC01116 promoted the development of colorectal cancer via modulating miR-9-5p/STMN1 axis.

Abstract
Purpose Synchronous colorectal liver metastasis (SCLM) had limited availability of tools to predict survival and tumor recurrence. LncRNA CRNDE and lncRNA SNHG7 have been proven to be closely related to cancer progression. However, the predictive value of lncRNA CRNDE and lncRNA SNHG7 in cancer prognosis is still unclear. The purpose of this study was to investigate whether lncRNA CRNDE and lncRNA SNHG7 could be used as promising biomarkers for prognosis prediction of SCLM patients who underwent hepatectomy. Methods The expression profile of lncRNA CRNDE and lncRNA SNHG7 in serum of SCLM patients was examined by qRT-PCR. The relationship between lncRNA expression and clinicopathological characteristics was analyzed. The Cox proportional-hazards regression model and Kaplan-Meier analysis were performed to analyze the association between lncRNA expression and overall survival (OS) and tumor recurrence of SCLM patients. Results Levels of lncRNA CRNDE and lncRNA SNHG7 in patients who underwent recurrence or death were significantly higher than that of patients with recurrence-free or survival (P<0.01). Both lncRNA CRNDE high level and lncRNA SNHG7 high level showed a significant correlation with differentiation of primary tumor, invasion depth of primary focus, lymph node metastases, number of liver metastases, and liver metastasis grade. High levels of lncRNA CRNDE or lncRNA SNHG7 predicted shorter recurrence time, shorter OS time, higher recurrence rate and lower OS rate. Furthermore, lncRNA CRNDE and lncRNA SNHG7 were independent risk factors for high recurrence and poor OS in SCLM underwent hepatectomy. Conclusion Taken together, lncRNA CRNDE and lncRNA SNHG7 could be promising biomarkers for prediction of OS and tumor recurrence in SCLM underwent hepatectomy.

Abstract
BACKGROUND Laparoscopic hepatectomy is more conducive to the rapid rehabilitation of patients after surgery compared with open hepatectomy. However, there have been no reports on performing laparoscopic resection for liver metastases in enterostomy patients. MATERIALS From December 2016 to April 2017, the Liver Surgery Department of the Peking Union Medical College Hospital received three patients who had focal liver lesions after colorectal cancer surgery and enterostomy. We performed laparoscopic hepatectomy for these three patients and reviewed relevant literature. RESULTS All of these three patients' post-operative recovery was good. We found three different positions of the stomas and the corresponding abdominal adhesions in these three patients. We also summarised several possible related surgical techniques. CONCLUSION For patients with colorectal cancer and enterostomy after an operation, implementation of laparoscopic hepatectomy is feasible. Further research is still required for a more comprehensive assessment of this surgical approach.

Sporamin suppresses growth of xenografted colorectal carcinoma in athymic BALB/c mice by inhibiting liver β-catenin and vascular endothelial growth factor expression. World J Gastroenterol 2019; 25:3196-3206. [PMID: 31333311 PMCID: PMC6626725 DOI: 10.3748/wjg.v25.i25.3196] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2019] [Revised: 05/14/2019] [Accepted: 06/01/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Colorectal cancer (CRC) is the third most common malignancy of the digestive tract and the fifth leading cause of cancer-related mortality in China. Sporamin, a Kunitz-type trypsin inhibitor isolated from sweet potato, is a potential anti-cancer agent with activities against a number of malignant tumor cells in vitro. The liver secretes a myriad of endocrine factors that may facilitate the growth and transformation of tumors in the development of CRC.
AIM To investigate the effects of sporamin on liver morphology and biomarkers of xenografted CRC in the liver of athymic BALB/c mice.
METHODS Twenty-seven male BALB/c nude mice were randomly divided into control, vehicle, and sporamin groups. Mice in the latter two groups were intraperitoneally xenografted with LoVo colorectal carcinoma cells and intragastrically infused with saline or sporamin (0.5 g/kg body weight/d), respectively, for 3 wk. Hematoxylin and eosin (HE) staining of the sections was performed to observe morphological changes in hepatic tissue and real-time fluorescent quantitative PCR (qPCR) and enzyme-linked immunosorbent assay (ELISA) were used to measure the expression of β-catenin and vascular endothelial growth factor (VEGF) in the liver.
RESULTS Sporamin significantly reduced the number and weight of tumor nodules formed in the abdominal cavity. Compared with the vehicle group, the mean tumor weight (± SD) in the sporamin group was significantly reduced (0.44 ± 0.10 g vs 0.26 ± 0.15 g) and the total number of tumors decreased from 93 to 55. HE staining showed that enlargement of the nucleus and synthesis of proteins within hepatocytes, as well as infiltration of inflammatory cells into the liver, were attenuated by sporamin. Immunohistochemical staining and ELISA showed that the concentrations of β-catenin and VEGF in the liver were significantly reduced by sporamin. Compared with the vehicle group, the expression of β-catenin measured in integrated optical density units per area was reduced in the sporamin group (47.29 ± 9.10 vs 26.14 ± 1.72; P = 0.003). Expression of VEGF was also reduced after sporamin intervention from 20.78 ± 2.06 in the vehicle group to 15.80 ± 1.09 in the sporamin group (P = 0.021). Compared with the vehicle group, the concentration of β-catenin decreased from 134.42 ± 22.04 pg/mL to 109.07 ± 9.65 pg/mL after sporamin intervention (P = 0.00002). qPCR indicated that compared to the vehicle group, relative mRNA expression of β-catenin and VEGF in the liver of mice in the sporamin-treated group was significantly reduced to 71% ± 1% (P = 0.000001) and 23% ± 7% (P = 0.00002), respectively, of the vehicle group levels.
CONCLUSION Sporamin down-regulates the expression and secretion of β-catenin and VEGF in the liver, which subsequently inhibits the transcription of downstream genes involved in cancer progression and angiogenesis.

Abstract
The present study aimed to compare gene expression profiles between colorectal cancer and adjacent normal tissues, and to perform a preliminarily analysis of the key genes and underlying molecular mechanisms implicated in colorectal cancer development. Gene expression microarray chips were used to screen genes that were differently expressed between colorectal cancer and adjacent normal tissues. Approximately 1,183 genes were differentially expressed in cancer tissues compared with adjacent normal tissues (P≤0.05; fold difference, >2.0), of which 570 genes were upregulated and 613 genes were downregulated. In total, 6 upregulated genes, including keratin 23, collagen type X α1, collagen type XI α1, cell migration-inducing hyaluronan-binding protein, transforming growth factor-β1 and V-Myc avian myelocytomatosis viral oncogene homolog, and 2 downregulated genes, including channel α subunit 7 and EPH receptor A7, were selected and validated using reverse transcription-quantitative polymerase chain reaction, which exhibited results that were consistent with the microarray analysis. These 1,183 differentially expressed genes were further classified into 71 groups based on their functions using gene ontology and pathway analyses. Kyoto Encyclopedia of Genes and Genomes analysis of these upregulated or downregulated genes suggested that 23 signaling pathways were involved. The present study preliminarily screened for and identified key genes and signaling pathways that may be closely associated with colorectal cancer development. However, subsequent gene function studies are required to verify these findings.

Abstract
Sphingosine kinase 1 (SphK1) plays an important role in colorectal carcinoma metastasis. However, whether SphK1 modulates epithelial-mesenchymal transition (EMT)-related marker expression and the underlying mechanisms remain unclear. In this study, in order to clarify this issue, we used various colorectal cancer (CRC) cell lines, Caco2, HT29, RKO and HCT116. Each of the cell lines was divided into 3 groups as follows: the control group, SKI-Ⅱ (SphK1 inhibitor) group and PF-562271 [focal adhesion kinase (FAK) inhibitor] group. The migratory ability of the cells was examined by Transwell chamber assay. The mRNA and protein expression levels of SphK1, FAK (p-FAK), Slug, vimentin, N-cadherin and E-cadherin were detected by PCR and western blot analysis, respectively. The results revealed that the suppression of SphK1 reduced the cell migratory ability, and decreased the expression of Slug, vimentin and N-cadherin; however, the expression of E-cadherin was increased. Moreover, the inhibition of SphK1 reduced the expression of p-FAK. The inhibition of FAK (p-FAK) also decreased the cell migratory ability, and decreased the expression of Slug, vimentin and N-cadherin, whereas the expression of E-cadherin was increased. Thus, our data suggest that SphK1 modulates the expression of EMT-related markers and cell migration by regulating the expression of p-FAK in CRC cells. Thus, SphK1 may play a functional role in mediating the EMT process in CRC.

Abstract
Gastric cancer is the third most common malignancy in China, and the liver is the most common metastasis site which is responsible for poor prognosis in advanced gastric cancer. Gastric cancer liver metastasis (GCLM) has long been regarded as a systemic disease, and chemotherapy is still the main treatment, although the efficacy is unsatisfying. Recently, active surgical resection is reported to be practicable and beneficial in highly selected cases. In addition, either radiofrequency ablation or hepatic arterial infusion can be used for unresectable locally advanced tumors. Management of liver metastasis is the key to significantly improve the prognosis of patients. Further research is needed to establish individualized modalities for these particular patients. We herein discuss the surgical treatment of GCLM.

Abstract
Background As a common malignant tumor, gastric carcinoma requires early diagnosis to improve treatment efficacy. MicroRNA (miR) molecules have highly conserved nucleotide sequences and can negatively regulate target gene expression at the translational level. miR-421 has been suggested to be related with gastric cancer occurrence. The gene polymorphism of miR-421, however, has not been reported. This study thus investigated the G/C polymorphism of miR-421 and its role in progression and prognosis of gastric cancer. Material/Methods A total of 96 gastric cancer patients were recruited in this study and tumor samples were collected from surgical resection. Single-nucleotide polymorphism (SNP) of miR-421 was determined by DNA sequencing for analyzing the correlation between lymph node metastasis and miR-421 genotypes. Logistic regression analysis was used to determine the relationship between genotype and risk factors of gastric cancer. Kaplan-Meier survival analysis was also performed to compare GG and GC carriers. Results Differential expression patterns existed between gastric cancer tissues and normal gastric mucosa. Logistic regression analysis showed GC and GG genotypes were risk factors for gastric cancer. Patients with lymph node metastasis had higher GG genotype frequency compared to those without metastasis. In survival analysis, GG carriers had shorter survival time than GC carriers. Furthermore, GG genotype was correlated with tumor prognosis (p<0.05). Conclusions G allele of miR-421 is a risk factor for gastric cancer. GG genotype is correlated with lymph node metastasis and prognosis, indicating it is a risk factor for gastric cancer.

Abstract
PURPOSE The role of minimally invasive colorectal resection for patients undergoing a simultaneous resection for synchronous liver metastases had not been established. This study compared the short- and long-term outcomes between minimally invasive and open colorectal resection for patients undergoing simultaneous resection for liver metastases. METHODS This study reviewed 101 consecutive patients undergoing simultaneous colorectal resection and R0 resection of synchronous liver metastases between January 2008 and December 2012. In the study, 36 consecutive patients who underwent minimally invasive colorectal resection were matched with 36 patients who had an open approach by propensity scoring. The analyzed variables included patient and tumor characteristics and short-term and long-term outcomes. RESULTS After propensity score matching, the two groups had similar clinicopathologic variables. No patient undergoing the minimally invasive procedure experienced conversion to the open technique. No postoperative mortality occurred in either group. In the minimally invasive group, the estimated blood loss (P < 0.007), bowel function return time (P < 0.016), and postoperative hospital stay (P < 0.011) were significantly lower than those in the open group, although the operating time was significantly longer (P < 0.001). No significant differences in postoperative complications were observed between the groups. The two groups did not differ significantly in terms of the 5-year overall survival rate (51 vs. 55 %; P = 0.794) and disease-free survival rate (38 vs. 27 %; P = 0.860). CONCLUSION Minimally invasive colorectal resection with simultaneous resection of liver metastases has an outcome similar to open approach but some short-term advantages.

Abstract
BACKGROUND Tumor deposits are one of the important influencing factors among the different editions of Tumor, Node, Metastasis classification. Incidence and prognosis of tumor deposits in stage I, II, and III colorectal cancer patients has been explored. The aim of this study was to determine the prognostic value of tumor deposits in stage IV colorectal cancer patients who underwent simultaneous resection for synchronous colorectal liver metastases (SCRLM). METHODS Clinicopathological and outcome data of 146 consecutive SCRLM patients who underwent simultaneous R0 resection between July 2003 and July 2013 were collected from our prospectively established SCRLM database. The prognostic value of tumor deposits was evaluated by Kaplan-Meier and Cox regression analysis. RESULTS Tumor deposits were detected in 41.8% (61/146) of these SCRLM patients. Tumor deposits were significantly correlated with lymph node metastasis and nerve invasion of the primary tumors (P=0.002, P=0.041; respectively). The Kaplan-Meier survival analysis revealed that the overall survival (OS) and disease-free survival (DFS) of SCRLM patients with tumor deposits were significantly poorer than those with no tumor deposits (P=0.039, P=0.001; respectively). And with multivariate analysis, we found that positive tumor deposits were significantly associated with shorter DFS independent of lymph node status (P=0.002). Subgroup analysis found that of the 57 SCRLM patients with negative lymph node status, the OS and DFS of patients with positive tumor deposits were significantly shorter than those with negative tumor deposits (P=0.002 and P=0.031, respectively). Of the 89 patients with positive lymph node status, the OS of patients with tumor deposits was not significantly different than those without tumor deposits (P=0.965); however, the DFS of patients with tumor deposits was significantly shorter than those with no tumor deposits (P=0.034). CONCLUSION Tumor deposits may be an independent adverse prognostic factor in SCRLM patients who underwent simultaneous R0 resection.

BACKGROUND The clinical benefits of conversion chemotherapy followed by liver resection for initially unresectable colorectal liver metastases are still controversial. The criteria for unresectability vary from one team to another. To clarify this issue, we retrospectively assessed the survival and characteristics of metastatic colorectal cancer (mCRC) patients with liver-limited disease (LLD) who underwent conversion therapy. METHOD Our criteria for resectability depended on the size of the remnant liver volume (>30 %) and expected function after removal of all metastases. Between December 2007 and September 2011, a total of 115 patients were diagnosed as having mCRC with LLD and received chemotherapy. Among them, 47 had tumors that were initially diagnosed as resectable. They underwent hepatic resection after chemotherapy (resected group). Of the 67 tumors were initially diagnosed as unresectable, 12 became resectable after chemotherapy (conversion group), leaving 55 tumors that remained unresectable after chemotherapy (unresected group). RESULTS The median follow-up was 25.2 months. Hepatic resection was more invasive in the conversion group than in the resected group. Median disease-free survival was significantly higher in the resected group than in the conversion group (p = 0.013). Overall survival (OS) was also higher in the resected group, but the difference was not significant (p = 0.36). However, OS was significantly higher in the conversion group than in the unresected group (p = 0.034). Multivariate analysis of the resected and conversion groups showed that OS was significantly negatively influenced by abnormal carcinoembryonic antigen levels at surgery (p = 0.037) and a hospital stay >30 days (p = 0.009). CONCLUSIONS Our results showed that conversion chemotherapy could contribute to longer OS in mCRC patients with LLD.

Abstract
Colorectal cancer is the second most common cancer in Hong Kong and its incidence is rising in economically developed Chinese cities, including Hong Kong and Shanghai. Several studies conducted in the People's Republic of China have characterized the unique molecular epidemiology of familial colorectal cancer syndromes and molecular biomarkers such as microsatellite instability and genetic mutations (eg, KRAS, NRAS, BRAF, PIK3CA, ERCC1) in Chinese populations. Interethnic differences in anticancer drug response and toxicity have been well described in many cancers, and this review examined the literature with regard to the tolerance of Chinese patients to commonly used chemotherapeutic regimens and targeted therapies for metastatic colorectal cancer. Studies on the pharmacogenomic differences in drug metabolizing and DNA repair enzymes between Chinese, North Asians, and Caucasian patients were also reviewed.

Abstract
Background It remains unclear which patients can benefit from simultaneous resection of synchronous colorectal liver metastases (SCRLMs). This study aimed to examine the prognostic value of patient- and tumor-related factors in predicting long-term outcomes of patients undergoing simultaneous resection of SCRLMs and to help patients select a suitable therapeutic regimen and proper surveillance. Methods Clinicopathological and outcome data of 154 consecutive SCRLM patients who underwent simultaneous resection between July 2003 and July 2013 were collected from our prospectively established SCRLM data and analyzed with univariate and multivariate methods, and the prognostic index (PI) was formulated based on the regression coefficients (β) of the Cox model. The patients were classified into high- and low-risk groups according to the PI value; the cut-off point was the third quartile. Results The 5-year overall survival rate was 46%, and the 5-year disease-free survival rate was 35%. Five factors were found to be independent predictors of poor overall survival (OS) by multivariate analysis: positive lymph node status, vascular invasion, BRAF mutation, the distribution of bilobar liver metastases (LMs) and non-R0 resection of LMs. Compared to low PI (≤5.978), high PI (>5.978) was highly predictive of shorter OS. Three factors were found to be independent predictors of poor disease-free survival (DFS) by multivariate analysis: tumor deposits, BRAF mutation and bilobar LM distribution. We also determined the PI for DFS. Compared to low PI (≤2.945), high PI (>2.945) was highly predictive of shorter DFS. Conclusions Simultaneous resection of SCRLM may lead to various long-term outcomes. Patients with low PI have longer OS and DFS, while those with high PI have shorter OS and DFS. Thus, patients with high PI may receive more aggressive treatment and intensive surveillance, This model needs further validation.

Quality assessment of clinical practice guidelines on the treatment of hepatocellular carcinoma or metastatic liver cancer. PLoS One 2014; 9:e103939. [PMID: 25105961 PMCID: PMC4126673 DOI: 10.1371/journal.pone.0103939] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2013] [Accepted: 07/04/2014] [Indexed: 02/05/2023] Open
Abstract
Objectives To assess the quality of the currently available clinical practice guidelines (CPGs) for hepatocellular carcinoma, and provide a reference for clinicians in selecting the best available clinical protocols. Methods The databases of PubMed, MEDLINE, Web of Science, Chinese Biomedical Literature database (CBM), China National Knowledge Infrastructure (CNKI), WanFang, and relevant CPGs websites were systematically searched through March 2014. CPGs quality was appraised using the Appraisal of Guidelines for Research & Evaluation (AGREE) II instrument, and data analysis was performed using SPSS 13.0 software. Results A total of 20 evidence-based and 20 expert consensus-based guidelines were included. The mean percentage of the domain scores were: scope and purpose 83% (95% confidence interval (CI), 81% to 86%), clarity of presentation 79% (95% CI, 73% to 86%), stakeholder involvement 39% (95% CI, 30% to 49%), editorial independence 58% (95% CI, 52% to 64%), rigor of development 39% (95% CI, 31% to 46%), and applicability 16% (95% CI, 10% to 23%). Evidence-based guidelines were superior to those established by consensus for the domains of rigor of development (p<0.001), clarity of presentation (p = 0.01) and applicability (p = 0.021). Conclusions The overall methodological quality of CPGs for hepatocellular carcinoma and metastatic liver cancer is moderate, with poor applicability and potential conflict of interest issues. The evidence-based guidelines has become mainstream for high quality CPGs development; however, there is still need to further increase the transparency and quality of evidence rating, as well as the recommendation process, and to address potential conflict of interest.

Is DWI/ADC a useful tool in the characterization of focal hepatic lesions suspected of malignancy? PLoS One 2014; 9:e101944.

Abstract
OBJECTIVE Apparent diffusion coefficient (ADC) values calculated through magnetic resonance imaging have been proposed as a useful tool to distinguish benign from malignant liver lesions. Most studies however included simple cysts in their analysis. Liver cysts are easy to diagnose, have very high ADC values and their inclusion facilitates differentiation in the ADC values between benign and malignant liver lesions groups. We prospectively evaluated the ability of ADC values to differentiate metastatic liver lesions from all benign or only solid benign liver lesions. MATERIAL AND METHODS Sixty-seven adult cancer patients with 188 liver lesions were evaluated. Lesions were categorized as metastatic or benign throughout imaging and clinical evaluation. One hundred and five (105) metastatic lesions and 83 benign lesions including hemangiomas (37), cysts (42), adenomas (2) and focal nodular hyperplasias (2) were evaluated. ADC values were calculated for each lesion utilizing two b values (0 and 600 sec/mm2). RESULTS The average ADC value for cysts was 2.4×10(-3) mm2/sec (CI: 2.1-2.6), for solid benign lesions was 1.4×10(-3) mm2/sec (CI: 1.1-1.7) and for metastases was 1.0×10(-3) mm2/sec (CI: 0.8-1.3). There was a difference between the ADC values of metastases and benign solid lesions (p<0.0001). With the ADC value of 1.5×10(-3) mm2/sec as a cut off it is possible to distinguish metastatic from benign liver lesions, including cysts, with an accuracy of 78%. But to distinguish metastatic from benign solid liver lesions the best ADC cut off value was 1.2×10(-3) mm2/sec and the accuracy drops to 71%. CONCLUSIONS ADC values proved to be helpful in the distinction between metastasis and benign solid hepatic lesions. But the exclusion of cysts in the analysis point out to a lower cut off value and lower accuracy than previously reported.

Abstract
Background Whether patients with resectable colorectal liver metastases (CRLM) receive survival benefit from neoadjuvant chemotherapy remains controversial. Methods We retrospectively analyzed 466 patients with resectable CRLM between 2000 and 2010. Patient characteristics and survival data were recorded. Results The patients were divided into one group with neoadjuvant chemotherapy (group NC, n = 121) and another without (group WN, n = 345). There was no difference in 5-year survival (52% vs. 48%) between the two groups. No significant differences were identified between the two groups in terms of 30-day mortality (1.7% vs. 1.2%) or morbidity (33.9% vs. 25.8%). A primary tumor at stage T4, ≥4 liver metastases, the largest liver metastasis ≥5 cm in diameter, and a serum CEA level ≥5 ng/ml were independent prognostic factors. By assigning one point to each, the patients were divided into a low-risk group (0–2) and a high-risk (3–4). The patients in the low-risk group received no survival benefit from neoadjuvant chemotherapy, whereas those in the high-risk group received survival benefit (5-year survival, 39% vs. 33%, P = 0.028). Conclusions Preoperative neoadjuvant chemotherapy did not increase mortality or complications. Not all resectable patients, only those with >2 independent risk factors, received survival benefit from neoadjuvant chemotherapy.

Abstract
AIM Safety and survival were investigated in patients treated according to expanded surgical indications for colorectal hepatic metastases. METHOD A retrospective analysis of all consecutive patients who underwent resection of colorectal hepatic metastases at Zhongshan Hospital from 2000 to 2010 was conducted. The patients were divided into two groups based on a change in the surgical indications introduced in 2005. Patients in Group I underwent hepatic surgery between 2000 and 2004 and those in Group II between 2005 and 2010. The clinicopathological data and survival rates of both groups were analysed. RESULTS There were 530 patients who underwent hepatic surgery between 2000 and 2010. After the expansion of surgical indications, the rate of surgical resection rose from 25.1 to 35.1% (P < 0.05). There was no significant difference in perioperative mortality (2.2% vs 0.9%) or morbidity (20.9% vs 29.8%). Recurrence occurred in 27.5% and 36.7% in Groups I and II, respectively, and 5-year overall survival was 43% and 49%, respectively (not significant). CONCLUSION Expanding the indications for surgical resection of hepatic metastases increased the resection rate but had no significant effect on survival.

Abstract
OBJECTIVE This study was designed to evaluate the long-time outcome of patients with colorectal liver metastasis (CRLM) undergoing different types of therapy and identify prognosis factors. METHODS From 2000 to 2010, 1,613 consecutive patients with CRLM were identified. Clinicopathological and outcome data were collected and analyzed by univariate and multivariate analyses. RESULTS Synchronous liver metastasis (SLM), female, grade III-IV, T4 and N positive of primary tumor, bilobar disease, number of liver metastases ≥ 4, size of largest liver metastases ≥ 5 cm, serum CEA level ≥ 5 ng/ml, and CA19-9 level ≥ 37 u/ml were the predictors of adverse outcome using univariate analysis. The median survival and 5-year survival rate for patients after resection of liver metastases was 49.8 months and 47%, better than that for those after other therapy. In addition, patients without treatment had the poorest survival. Sixty-four initially unresectable patients underwent surgery after conversion therapy with a median survival of 36.9 months and a 5-year survival of 30%. By multivariate analysis, SLM, poorly differentiated primary tumor, number of liver metastases ≥ 4, size of largest liver metastases ≥ 5 cm, and no surgical treatment of liver metastases were found to be independent predictors of poor survival. CONCLUSIONS Patients with CRLM could get long-term survival benefit from different types of therapy, and resection of liver metastases was the optimal strategy. A predictive model using these above five factors may be of use in stratifying patients who may benefit from intensive surveillance and adjuvant therapy.

Abstract
AIM To compare the surgical treatment outcomes between patients with colorectal liver metastases (CLM) and non-colorectal liver metastases (NCLM). METHODS The study population consisted of 132 patients undergoing hepatectomy at Tianjin Medical University Cancer Hospital between January 1996 and December 2008. Survival analyses were used to assess the differences in prognosis and survival between groups. RESULTS The primary tumor site was colorectal in 60 (45.5%), breast in 16 (12.1%), lung in 14 (10.6%), non-colorectal gastrointestinal in 12 (9.1%), genitourinary in 10 (7.6%), pancreatobiliary tumor (n = 8, 6.1%) and others in 12 (9.1%). A curative liver resection was performed in all patients by pathological findings. After a median follow-up of 32 months, the overall 3- and 5-year survival rate was 44.7 and 29.5% in all patients, respectively. The 3- and 5-year survival rates were 53.3 and 36.7% for liver metastases from colorectal tumors, 62.5 and 43.8% from breast, 60.0 and 40.0% from genitourinary neoplasm, 41.7 and 25.0% from non-colorectal gastrointestinal cancer, 28.5 and 15.0% from lung, 12.5 and 0% from pancreatobiliary malignancies, and 41.7 and 8.3% from other sites, respectively. CONCLUSIONS Hepatic resection is an effective and safe treatment for liver metastases mainly depending on primary tumor sites. Hepatic metastases from non-colorectal gastrointestinal cancer, pulmonary and pancreatobiliary malignancies have the worst prognosis; those from breast and genitourinary neoplasm show the best prognosis.
