Trial summary

According to current clinical guidelines adjuvant treatment in colon cancer is not recommended in patients with stage I and IIA, and in patients with high risk factors (IIB) adjuvant treatment has not shown a clear benefit in recurrence or survival. However, more than 20% of these patients have recurrence. Read more about this study

About this study

Official title: Influence of the Presence of Ganglionar Micrometastases Associated With an Elevation of Angiogenesis on the Evolution of Colon Cancer. Prognostic Value of the Levels of VEGF-A Anf VEGF-C

According to current clinical guidelines adjuvant treatment in colon cancer is not recommended in patients with stage I and IIA, and in patients with high risk factors (IIB) adjuvant treatment has not shown a clear benefit in recurrence or survival.

However, more than 20% of these patients have recurrence. This high percentage raises the possible understaging of current methods, so in recent years different methods have been developed in order to obtain a correct staging that have allowed a greater detection of micrometastasis (less than 2mm).

The performance of the detection technique of the sentinel node in colon cancer allows us to perform this study in 1-3 lymph nodes, so that performing in all the nodes removed in a piece would be imposible in daily clinical practice for time, personnel and economic resources needed to do it.

This technique achieves between 5-15% of overstaging which means that in stages I and IIA can lead to a change in the indication of adjuvant treatment. Despite this, the influence of ganglion micrometastases on survival is still controversial. This leads to consider other factors that may influence tumor aggressiveness, such as an increase in angiogenesis that allows the viability of implants less than 2mm. Therefore, we propose that elevated levels of VEGF (angiogenesis marker) in patients with sentinel lymph node micrometastases can lead to a worse prognosis.

Based on these premises, the aim of the study is to assess the correlation between the levels of serum and tumor VEGF-A and VEGF-C (markers of angiogenesis and lymphangiogenesis) and the evolution of the disease in patients with lymph node micrometastases.

Read the detailed description

Once the investigators have all the data of the patients included in the study, and the ELISA analysis of the serum and tissue VEGF levels has been performed, we hope to determine a threshold level of VEGF in blood and tissue that modifies the prognostic implications of the presence of ganglionic micrometastasis, which increases the viability of these implants.

If the investigators determine this threshold and demonstrate that high levels of this molecule, both in blood and tissue, increase the rate of recurrence in patients with lymph node micrometastases, would be suggested a change in the indications for adjuvant treatment in patients in whom it is not currently indicated (stages I-IIA and IIB without other factors of poor prognosis) considering that they have an independent bad prognostic factor such as a high level (above our threshold) of VEGF. This allows the investigators to select those patients who would benefit from chemotherapy treatment despite not being indicated according to the current treatment guidelines (NCCN 2018).

Questions about this trial

What is this clinical trial studying?

An observational study of Colorectal Cancer and Angiogenesis, run by Fundació Institut de Recerca de l'Hospital de la Santa Creu i Sant Pau at 1 site in Spain.

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 3 inclusion and 5 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 30 Oct 2019. 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 Spain. 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 IRENE GÓMEZ TORRES, PHD (+34 678309987, irenegomeztorres@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

recurrence (time frame: 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 30 Oct 2019.
