About this study

This is an observational cohort study aimed at investigating changes in hippocampal function and its impact on cognitive function in newly diagnosed nasopharyngeal carcinoma patients without metastasis, from baseline to a period after radiotherapy.

Nasopharyngeal Carcinoma

What is being measured

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

  1. Incidence of cognitive decline.

    In a cohort of nasopharyngeal carcinoma patients undergoing intensity-modulated radiotherapy, we will observe the incidence of cognitive decline from baseline, at the end of radiotherapy, and post-treatment. The study will investigate the impact of hippocampal radiation dose on cognitive function in these patients and summarize the patterns of change.

    Measured: 2 years

Secondary outcomes (6)
  1. The relationship between hippocampal atrophy, radiation dose, and cognitive function after radiotherapy.

    Statistical analysis will be conducted based on the changes in hippocampal volume before and after radiotherapy, tumor target dose, hippocampal irradiation dose, and cognitive function scale test results.

    Measured: 2 years

  2. The relationship between hippocampal functional impairment, radiation dose, and cognitive function after radiotherapy.

    Using resting-state fMRI technology, individual local brain function and default network information will be obtained. Variance analysis will be used to compare hippocampal changes before and after radiotherapy, clarifying the relationship between hippocampal functional damage, radiation dose, and cognitive function post-radiotherapy.

    Measured: 2 years

  3. The relationship between hippocampal microstructural damage, radiation dose, and cognitive function after radiotherapy.

    Using Synthetic MRI imaging technology, imaging data of nasopharyngeal carcinoma patients will be collected before and after radiotherapy to provide individual whole-brain quantitative parameters and hippocampal microstructural information. Variance analysis will be used to compare pre- and post-radiotherapy differences, elucidating the relationship between hippocampal microstructural damage, radiation dose, and cognitive function.

    Measured: 2 years

  4. The relationship between hippocampal microvascular injury, radiation dose, and cognitive function after radiotherapy.

    Based on multimodal MRI technology, this study will explore the microvascular status and changes in blood perfusion in nasopharyngeal carcinoma patients before and after radiotherapy, clarifying the relationship between hippocampal microvascular damage, radiation dose, and cognitive function post-radiotherapy.

    Measured: 2 years

  5. The impact of different chemoradiation treatment modalities on the occurrence of cognitive decline.

    According to the TPS planning system dose statistics and dose-volume histogram, we will quantify the irradiation dose-volume of critical organs, including: hippocampal volume, tumor target volume, clinical target volume, and planning target volume; maximum dose and average dose of the hippocampus, as well as parameters on the dose-volume histogram. The cognitive function of patients after radiotherapy will be evaluated based on common adverse events as defined by CTCAE.

    Measured: 2 years

  6. The correlation between cognitive decline after radiotherapy and quality of life.

    "The quality of life will be prospectively assessed before treatment and followed up continuously after radiotherapy."

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Nasopharyngeal Carcinoma (NPC) and Cognitive Function, run by Sun Yat-sen University.

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 10 inclusion and 15 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: opening soon, as of the sponsor's last update on 19 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.

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 Haiqiang Mai, Dr (86-20-8734-3643, maihq@mail.sysu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of cognitive decline. (time frame: 2 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 19 Nov 2024.
