In fact, these aspects are critical for inducing cell migration and invasion, supporting the formation of pre-metastatic niches and circulating tumor cells that dictate metastatic spread Another key [6] challenge is therapeutic management.

EMT and prognosis of colorectal cancer (CRC) have not been elucidated. Therefore, the present study was designed to set up a reliable ratio of CD163+/CD68+ to assess M2-polarized TAMs infiltration in the tumor center (TC) and tumor invasive front (TF) and to further evaluate their prognostic value and biological effects on tumor cells in CRC.

In fact, a SignateraTM test detecting custom-built plasma cell-free DNAs could predict relapse after surgical resection of stage I III CRC with high sensitivity [17].

In nonmetastatic colorectal cancer (CRC), pre-operative CTC detection was re-ported to be an independent prognostic marker (Bork et al., 2015).

They found 27-fold hazard ratio for relapse in patients with positive CTC status. A membrane

Review Article

For example, in patients with localized GI tumors [colorectal cancer (CRC), gastric or gastroesophageal (GE) cancer, and pancreatic cancer] ctDNA can be detected in 48 73% of patients (24). However, as tumor burden increases, deep surveillance of sufficient genomic space increases ctDNA detection to nearly 100% (25). For this reason and because

Circulating MicroRNAs: Potential Biomarkers for Cancer

Their concepts extended to cancer in humans, where circulating levels of miR-141 (a miRNA expressed in prostate cancer) can distinguish patients with prostate cancer from healthy controls. Furthermore, the elevated serum levels of miR-200a and miR-200b in most patients with pancreatic cancer could have diagnostic utility [25].

Metastasis‑associated in colon cancer 1: A promising

Colorectal cancer (CRC) is the fourth most frequent type of malignancy in the world. Metastasis accounts for >90% mortalities in patients with CRC. The metastasisassociated - in colon cancer 1 (MACC1) gene has been identified as a novel biomarker for the prediction of metastasis and disease

In almost all types of cancer, the liver is a common site for metastatic disease. Blood supply of the liver facilitates entrapment of circulating cancer cells, which can develop into liver metastases.

Title: Individualized ctDNA Fingerprints to Monitor Treatment

The highest number of patients had colorectal cancer (CRC), followed by liver cancer, glioma [combined result of blood and cerebrospinal fluid (CSF) tests], and lung cancer in significant numbers; other cancer types included gastric cancer, cholangiocarcinoma, and pancreatic cancer.

of CRC and an influence on its clinicopathological characteristics. Two studies showed an inverse correlation between tumour stage/grade and APN[29,30]. Furthermore, low pre-surgical APN levels were found in a higher proportion of relapsing patients, suggesting that APN may have potential to act an adjunctive tool to predict relapse.

Circulating tumor cells with karyotyping as a - BMC Cancer

Circulating tumor cells (CTCs) are tumor cells dissem-inated from primary or metastatic tumors into blood cir-culation and act as the origin of distant metastasis [10]. Many studies have reported that enumeration of CTCs is significant to evaluate a prognosis, predict therapy ef-ficacy, and monitor recurrence or metastasis in various

Also the association of 7 microRNAs, including miR-10b, miR-21, miR-223, miR-338, let-7a, miR-30a-5p and miR-126 was shown with relapse-free and overall survival in GC patients [11-12].
