Clinical Trial Summary

The present study is aimed at detecting and measuring mRNA levels of genes involved in epithelial to mesenchymal transition (EMT) in biological samples, i.e. in peripheral blood samples of colorectal cancer (CRC) patients and healthy controls, to determine the presence of disease, its progression and risk of recurrence.

Description:

The investigators first provided evidence that human colorectal cancer (CRC) cells can undergo EMT during local invasion, and that EMT transcription factors (i.e.Twist family basic helix-loop-helix transcription factor 1 (TWIST1)) are increased in the blood of CRC patients. In addressing the relevance of EMT in the metastatic process, the prognostic role of M-like cancer cells entering into the circulation remains to be determined.

Currently, the notion that cancer disseminates via the circulation led to increased attention on the identification of circulating tumor cells (CTCs) in blood samples ("liquid biopsy"; LB), so far mostly based upon epithelial (E) markers. However, an un-biased evaluation of CTCs, providing meaningful information for cancer diagnosis up to therapy, cannot exclude cells with M features. LB data show that circulating TWIST1 mRNAs are significantly and steadily increased in the blood of CRC patients. These findings indicate that EMT players in the circulation change during different phases of CRC progression.

The present study is aimed at detecting and measuring messenger ribonucleic acid (mRNA) levels of genes involved in epithelial to mesenchymal transition in biological samples, i.e. in peripheral blood samples of tumor patients, to determine the presence of disease, its progression and possibly the risk of recurrence, even in patients who will be treated with adjuvant therapy on clinical ground.

Aim of this study is to depict the molecular profile of EMT transcription factor (EMT-TFs) variations in the blood of patients with early, intermediate or advanced CRC, with respect to disease progression and delivered treatments.

Primary endpoint: To determ the stage, the remission or the progression of a colorectal cancer in a colorectal cancer affected subject not administered with an appropriate antitumor treatment (e.g., neo-adjuvant therapy) comprising the step of assaying a biological sample from said subject for the presence of a panel of mRNAs encoding for transcription factors involved in epithelial to mesenchymal transition.

Secondary endpoint: To identify biomarkers suitable for the selection of patients amenable of responsiveness to medical and surgical treatment.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Assessments of diagnosis of CRC by EMT-TF mRNA levels in blood	To determine the stage, the remission or the progression of a colorectal cancer in a colorectal cancer affected subject not administered with an appropriate antitumor treatment (e.g., neo-adjuvant therapy) comprising the step of assaying a biological sample from said subject for the presence of a panel of mRNAs encoding for transcription factors involved in epithelial to mesenchymal transition.	Analysis at day 0: at diagnosis or before surgery for CRC patients; before colonoscopy in controls
Secondary	Prediction of prognosis of CRC by EMT-TF mRNA levels in blood	To identify biomarkers suitable for the selection of CRC patients amenable of responsiveness to medical and surgical treatment.	Analysis at least: 7-15 days from surgery (T1), 30 days (T2) from surgery, 6 months (T3) from surgery, 1 year (T4) from surgery
