Evaluation of the correlation of vasculogenic mimicry, ALDH1, KiSS-1, and MACC1 in the prediction of metastasis and prognosis in ovarian carcinoma.

ABSTRACT: Recurrence and metastasis are the usual manifestations of treatment failure of epithelial ovarian carcinoma (EOC). Vasculogenic mimicry (VM; blood supply development often seen in highly aggressive cancers), aldehyde dehydrogenase 1 (ALDH1, cancer stem cell biomarker), KiSS-1 (suppressor of tumor metastasis), and metastasis associated in colon cancer-1 (MACC1) are all useful predictive factors for metastasis and prognosis in various cancers. In this study, we analyzed associations among VM, ALDH1, KiSS-1, and MACC1 in EOC, and their respective correlations with clinicopathological characteristics and survival in EOC.Positive rates of VM, ALDH1, KiSS-1, and MACC1 in 207 whole EOC tissue samples were detected by immunohistochemistry. Patients' clinical data were also collected.Levels of VM, ALDH1, and MACC1 were significantly higher, and levels of KiSS-1 significantly lower, in EOC tissues than in benign ovary tumors. Levels of VM, ALDH1, KiSS-1, and MACC1 were associated significantly with tumor/lymph node/metastasis (LNM) grade, implantation, and International Federation of Gynecology and Obstetrics (FIGO) stage, and with patients' overall survival (OS); whereas the KiSS-1+ subgroup had significantly longer OS than did the KiSS-1- subgroup. In multivariate analysis, high VM, ALDH1 or MACC1 levels, FIGO stage, implantation and low KiSS-1 levels were independently associated with shorter OS in patients with EOC.VM and expressions of ALDH1, KiSS-1, and MACC1 represent promising markers for metastasis and prognosis, and potential therapeutic targets for EOC.

Project description:Metastasis-associated in colon cancer 1 (MACC1) has been reported to promote tumor cell invasion and metastasis. Cancer stem cells and epithelial-mesenchymal transition (EMT) have also been reported to promote tumor cell proliferation, invasion, and metastasis. KiSS-1, a known suppressor of metastasis, has been reported to be down-regulated in various tumors. However, the associations of MACC1, CD44, Twist1, and KiSS-1 in colonic adenocarcinoma (CAC) invasion and metastasis remain unclear. The purpose of this study is to investigate the roles of MACC1, CD44, Twist1, and KiSS-1 in CAC invasion and metastasis and their associations with each other and with the clinicopathological characteristics of CAC patients.Immunohistochemistry and multivariate analysis were carried out to explore the expression of MACC1, CD44, Twist1, and KiSS-1 in 212 whole-CAC-tissue specimens and the corresponding normal colon mucosa tissues. Demographic, clinicopathological, and follow-up data were also collected.The results of this study showed MACC1, CD44, and Twist1 expression to be up-regulated, and KiSS-1 expression was down-regulated in CAC tissues. Positive expression of MACC1, CD44, and Twist1 was found to be positively correlated with invasion, tumor grades, and lymph- node-metastasis (LNM) stages and tumor-node-metastasis (TNM) stages for patients with CAC. Positive expression of KiSS-1 was inversely associated with invasion, tumor size, LNM stage, and TNM stage. The KiSS-1-positive expression group had significantly more favorable OS than did the KiSS-1-negative group. Univariate analysis indicated that overexpression of MACC1, CD44, and Twists1 was negatively associated with longer overall survival (OS) time, and there was a positive relationship between KiSS-1-positive expression and OS time for patients with CAC. Multivariate Cox analysis demonstrated that overexpression of MACC1, CD44, Twist1, and low expression of KiSS-1 and LNM and TNM stages were independent predictors of prognosis in patients with CAC.The results in this study indicated that levels of expression of MACC1, CD44, Twist1, and KiSS-1 are related to the duration of OS in patients with CAC. MACC1, CD44, Twist1, and KiSS-1 may be suitable for use as biomarkers and therapeutic targets in CAC.

Project description:BackgroundMetastasis is the most frequent cause of treatment failure and death in colorectal cancer. Early detection of tumors and metastases is crucial for improving treatment strategies and patient outcome. Development of reliable biomarkers and simple tests routinely applicable in the clinic for detection, prognostication, and therapy monitoring is of special interest. We recently identified the novel gene Metastasis-Associated in Colon Cancer 1 (MACC1), a key regulator of the HGF/Met-pathway. MACC1 is a strong prognostic biomarker for colon cancer metastasis and allows identification of high-risk subjects in early stages, when determined in patients' primary tumors. To overcome the limitation of a restricted number of molecular analyses in tumor tissue, the establishment of a non-invasive blood test for early identification of high-risk cancer patients, for monitoring disease course and therapy response is strongly needed.Methodology/principal findingsFor the first time, we describe a non-invasive assay for quantification of circulating MACC1 transcripts in blood of more than 300 colorectal cancer patients. MACC1 transcript levels are increased in all disease stages of the cancer patients compared to tumor-free volunteers. Highest MACC1 levels were determined in individuals with metastases (all P<0.05). Importantly, high MACC1 levels correlate with unfavorable survival (P<.0001). Combining MACC1 with circulating transcripts of the metastasis gene S100A4, a transcriptional target of the Wnt/?-catenin-pathway, improves survival prediction for newly diagnosed cancer patients.Conclusion/significanceThis blood-based assay for circulating MACC1 transcripts, which can be quantitated on a routine basis, is clinically applicable for diagnosis, prognosis, and therapeutic monitoring of cancer patients. Here we demonstrate the diagnostic and prognostic value of circulating MACC1 transcripts in patient plasma for metastasis and survival. Since MACC1 represents a promising target for anti-metastatic therapies, circulating MACC1 transcripts may prove to be an ideal read-out for monitoring therapeutic response of future interventions targeting MACC1-induced metastasis in cancer patients.
