About this study
Official title: Timing To Minimally Invasive Surgery After Neoadjuvant Chemoradiotherapy For Rectal Cancer: A Multicenter Randomized Controlled Trial - Biomarkers SubStudy
Neoadjuvant chemoradiotherapy (nCHT) followed by surgery is the mainstay treatment for locally advanced rectal cancer, leading to significant decrease in tumor size (downsizing) and a shift towards earlier disease stage in the primary tumor and lymph nodes (downstaging). Extensive histopathological work-up of the tumor specimen after surgery including tumor regression grading (TRG) and lymph node status (ypN) helped to visualize individual tumor sensitivity to CRT retrospectively. Since the response to nCHT is heterogeneous, however, valid biomarkers are needed to monitor tumor response. A relevant number of studies aimed to identify molecular markers retrieved from tumor tissue while the relevance of blood-based biomarkers is less stringent assessed.
As a potential alternative to CEA and ctDNA, microRNAs (miRNAs) are currently under investigation to serve as blood-based biomarkers. miRNAs are small, noncoding RNAs that regulate gene expression by post-transcriptional mRNA binding, which promotes the destabilization of target miRNAs. The target specificity of miRNAs is largely predetermined by their so-called "seed-sequence" (containing nucleotides at position 2-7 of the miRNA). They are highly conserved between species, stable and easy detectable even in small concentrations. They have been widely analyzed in physiological and pathological processes, and their expression is tissue specific.

Neoadjuvant chemoradiotherapy (nCHT) followed by surgery is the mainstay treatment for locally advanced rectal cancer, leading to significant decrease in tumor size (downsizing) and a shift towards earlier disease stage in the primary tumor and lymph nodes (downstaging). Extensive histopathological work-up of the tumor specimen after surgery including tumor regression grading (TRG) and lymph node status (ypN) helped to visualize individual tumor sensitivity to CRT retrospectively. Since the response to nCHT is heterogeneous, however, valid biomarkers are needed to monitor tumor response. A relevant number of studies aimed to identify molecular markers retrieved from tumor tissue while the relevance of blood-based biomarkers is less stringent assessed.
Blood samples, i.e. Liquid Biopsy, however, offer several advantages:
- Taking blood samples is less invasive, less expensive, easy to schedule, and nearly without any severe complications.
- Blood samples are a source of fresh DNA and RNA, without modifications due to preservatives; especially in the case of rectal cancer, beyond intratumoral heterogeneity, tumor biopsies are in general accompanied by normal, adenomatous or stromal tissue. This contamination may affect results of molecular analyses
- Investigating blood from patients can account for molecular heterogeneity and surrogate for tumor burden since tumor-derived fragments or biomarkers are collected from all tumor cells in a patients' body through circulation.
- Liquid biopsy may offer both the possibility of dynamic monitoring under treatment and the possibility to assess disease activity even after pathologic complete response (pCR) or after resection of the tumor when no tissue is left for molecular analyses.
In clinical routines, to date, carcinoembryonic antigen (CEA) is established as a colorectal cancer (CRC) related tumor marker but is not recommended as a screening test for colorectal cancer. First, normal levels of CEA do not exclude the possibility of a colorectal cancer. Second, an elevated CEA is not categorically associated with CRC, or in the period of follow-up with disease progression. Circulating tumor DNA (ctDNA) represents nowadays, the main approach to monitor tumor burden and therapy resistance, to evaluate the presence of residual disease after potentially curative treatment and to monitor disease recurrence with high sensitivity and specificity.
As a potential alternative to CEA and ctDNA, microRNAs (miRNAs) are currently under investigation to serve as blood-based biomarkers. miRNAs are small, noncoding RNAs that regulate gene expression by post-transcriptional mRNA binding, which promotes the destabilization of target miRNAs. The target specificity of miRNAs is largely predetermined by their so-called "seed-sequence" (containing nucleotides at position 2-7 of the miRNA). They are highly conserved between species, stable and easy detectable even in small concentrations. They have been widely analyzed in physiological and pathological processes, and their expression is tissue specific.
To date, no screening approach to identify relevant miRNAs as biomarkers in blood of patients with rectal cancer was undertaken.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
miRNADiagnostic test
15 ml of whole blood samples are collected in Vacutainer tubes with spray-coated K2EDTA and stored at room temperature. To minimize the hemolysis and nucleic acids degradation, plasma separation undergoes within 2 h.
Within 1 h, tubes are subjected to a first centrifugation step at 2200 x g and room temperature for 15 min. Plasma supernatants are transferred to 15 mL tubes, carefully avoiding contact with the lymphocytic ring, and tubes are centrifuged a second time at 3000 x g and RT for 10 min to remove cellular debris.
Plasma samples are then collected into 1.5 mL cryovials and all the aliquots are stored at -80 °C.
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in expression levels of plasma miRNA
the association of variation between preneoadjuvant and postneoadjuvant expression levels of miRNA with pCR
Measured: 5 years
Secondary outcomes (2)
miRNA expression and surgery
changes in expression levels of miRNA following complete surgical resection with disease-free survival
Measured: 5 years
miRNA expression and surveillance
the relation between changes in miRNA during surveillance and tumor relapse
Measured: 5 years

Questions about this trial
What is this clinical trial studying?
An observational study of Rectal Cancer, run by Azienda Ospedaliera SS. Antonio e Biagio e Cesare Arrigo di Alessandria at 1 site in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 16 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Igor Monsellato, PhD (+390131206078, igor.monsellato@ospedale.al.it), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in expression levels of plasma miRNA (time frame: 5 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03962088, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Apr 2024.
