Trial summary

Squamous cell carcinoma of the anal canal is a relatively rare cancer (less than 3% of digestive cancers) but its incidence has been increasing in recent decades, probably because of its association with HPV (human papillomavirus) infection. Read more about this study

About this study

Squamous cell carcinoma of the anal canal is a relatively rare cancer (less than 3% of digestive cancers) but its incidence has been increasing in recent decades, probably because of its association with HPV (human papillomavirus) infection. Its extension is mainly locoregional pelvic by lymphatic route, rarely metastatic. The standard treatment nowadays is radiotherapy combined with chemotherapy for locally advanced tumors (T2 or more corresponding to a size of 2 cm or more, or N+): mitomycin C and 5-FU (or capecitabine). While the 5-year disease control rates are excellent in localized forms, around 80%, for locally advanced tumors, the prognosis is poorer, with only 70% progression-free survival at 3 years in patients treated with radiochemotherapy. In these patients, it seems particularly interesting to understand the mechanisms of tumor resistance to treatments, in order to increase their efficacy and to propose new therapeutic targets.

The microenvironment of solid tumors, which has been extensively studied in the last two decades, is now recognized as a major factor in tumor development and invasion. Immune cells, and more particularly macrophages, represent an essential component of the tumor microenvironment, and constitute a link between innate and adaptive responses. The presence of tumor-associated macrophages (TAMs), and in particular M2 macrophages, with an anti-inflammatory and anti-tumor action (as opposed to M1 macrophages which are on the contrary tumoricidal and pro-inflammatory), has been studied in many cancers, such as head and neck squamous cell carcinoma, hepatocellular carcinoma, cervical squamous cell carcinoma, and non-small cell lung cancer. To investigator's knowledge, it has not been studied in squamous cell carcinoma of the anal canal.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Effect of tumor-associated macrophages on treatment efficacy in locally advanced

    This outcome corresponds to tumor recurrence (local or distant) at 1 year.

    Measured: Year 1

Secondary outcomes (1)

  1. Phenotype of tumor-associated macrophages

    This outcome corresponds to distribution of tumor-associated macrophages according to their phenotype, M1 or M2, and their location (intra-tumor, peri-tumor stroma).

    Measured: Year 1

Questions about this trial

What is this clinical trial studying?

An observational study of Squamous Cell Carcinoma, run by Fondation Hôpital Saint-Joseph at 1 site in France.

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 4 inclusion and 6 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 7 Mar 2023. 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 France. 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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Effect of tumor-associated macrophages on treatment efficacy in locally advanced (time frame: Year 1). 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 NCT05019235, which also lists 5 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 7 Mar 2023.
