Trial summary

Non-melanocytic skin cancers are the most common type of cancer worldwide. In the development of this cancer type, environmental factors such as UV and smoking are emphasized. Epigenetics are genetic conditions that develop due to environmental factors and can be inherited. Read more about this study

About this study

Non-melanocytic skin cancers are the most common type of cancer worldwide. In the development of this cancer type, environmental factors such as UV and smoking are emphasized.

Epigenetics are genetic conditions that develop due to environmental factors and can be inherited. Epigenetic modifications such as DNA methylation play an integral role in carcinogenesis, cancer progression and metastasis.

The TGF-/ SMAD4 pathway plays a tumor suppressive role in cancer pathogenesis. Epigenetic changes in this pathway also lead to a decrease in expression level, leading to different types of cancer. However, there is no study showing the epigenetic relationship between non-melanocytic skin cancer and SMAD4 methylation.

In this study we planned, it was aimed to show the change in SMAD4 methylation and SMAD4 RNA expression level in cancerous tissue. In addition, it is planned to measure the SMAD4 protein positivity rate in non-melanocytic cancers as an immunohistochemical marker.

In this context, 60 patients who applied to Trakya University Dermatology and Venereal Diseases Outpatient Clinic and diagnosed with non-melanocytic skin cancer clinically and dermoscopically will be included in the study. Tissue materials obtained from both cancerous and intact skin of the patients will be examined in Trakya University Medical Biophysics and Medicine Pathology laboratories through various steps.

Our project is the first study to be conducted on this subject in terms of handling all non-melanocytic skin cancers, using human tissue and having a large sample.

In addition, with the data to be obtained; We think that better clarification of the role of SMAD4 in non-melanocytic cancers and the use of SMAD4 as both a prognostic factor and an immunohistochemical marker in future studies will prevent this study.

Again, we anticipate that different treatment modalities will be developed and different functional studies can be designed through this pathway.

Questions about this trial

What is this clinical trial studying?

A study testing SMAD4 expression and methylation in people with Basal Cell Carcinoma, run by Trakya University at 1 site in Turkey (Türkiye).

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 18 Feb 2021. 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 Turkey (Türkiye). 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 Yildiz Gursel, MD (90 505 537 30 63, yildizgrsl@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Detection of SMAD4 methylations and expression (time frame: 2 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 NCT04759261, which also lists 1 linked publication.

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 18 Feb 2021.
