Evaluating fatigue and molecular mechanisms in cancer patients undergoing combined chemotherapy and radiation therapy

Official title: An Evaluation of Changes in the Relationships Between Fatigue and Molecular Mechanisms in Cancer Patients Receiving Curative-Intent Combined Chemotherapy and Radiation Therapy (CCRT)

Run by University of California, San Francisco · NCT06633224 · Data updated 2026-11-12

This study is testing how fatigue affects cancer patients getting both chemotherapy and radiation therapy, and whether certain genes and molecules are linked to how tired they feel during treatment.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 years old who are starting CCRT and have not received prior cancer treatments in the past year.

Probably not a fit

Patients who have received prior systemic therapies or radiation therapy within the past year may not benefit from this study.

What this trial studies

This observational study aims to investigate cancer-related fatigue (CRF) in patients receiving standard combined chemotherapy and radiation therapy (CCRT). It will assess the relationship between molecular characteristics and CRF severity at various stages of treatment. The study will also explore the association between changes in CRF and gene expression levels, as well as circulating cytokine levels. Additionally, predictive models for CRF and chemotherapy-induced peripheral neuropathy (CIPN) severity will be developed using demographic and clinical data.

Why it matters

Potential benefit: If successful, this study could lead to better management strategies for cancer-related fatigue, improving the quality of life for cancer patients.

How similar studies have gone: While studies on cancer-related fatigue exist, this specific approach focusing on molecular mechanisms and predictive modeling is relatively novel.
