About this study

Patients with cancers that are sensitive to radiotherapy treatment and/or patients who have experienced severe acute/ late side effects to radiotherapy will be recruited to the study. Blood and/or matched tumour-normal tissue pairs will be collected. Blood and/or tissue samples will be processed and studied for genetic and biochemical markers that have potential to be used for predicting sensitivity to radiation.

What is being measured

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

  1. To identify genes or molecular pathways that are associated with radiation sensitivity in blood and tissue samples

    Whole exome sequencing, single nucleotide polymorphism (SNP) assays

    Measured: Blood is taken at informed consent; tissue is from archived sample

  2. Change in immune profile of blood and tissue after radiation

    Mass cytometry using CyTOF technology will be used to detect the immune cell population

    Measured: Blood is taken at informed consent; tissue is from archived sample

  3. To identify proteins that are associated with radiation sensitivity in tissue samples

    Immunohistochemistry will be used to detect protein expression

    Measured: Tissue is from archived sample

  4. To identify RNA expression pathways that are associated with radiation sensitivity in blood and tissue samples

    RNA sequencing

    Measured: Blood is taken at informed consent; tissue is from archived sample

Questions about this trial

What is this clinical trial studying?

An observational study of Nasopharyngeal Cancer and Prostate Cancer, run by National Cancer Centre, Singapore at 1 site in Singapore.

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 2 inclusion and 1 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: looking for participants now, as of the sponsor's last update on 11 Jun 2025. 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 Singapore. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Melvin Chua, MD (melvin.chua.l.k@singhealth.com.sg), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To identify genes or molecular pathways that are associated with radiation sensitivity in blood and tissue samples (time frame: Blood is taken at informed consent; tissue is from archived sample). The study lists 4 primary outcomes in all. 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 11 Jun 2025.
