Summary

This trial studies if time-restricted eating can reduce side effects of radiation or chemoradiation in patients with prostate, cervical, and rectal cancers. It compares fasting periods to nutritional counseling to see which helps more with treatment side effects and overall health.

Who is the study for?
This trial is for adults with high-risk prostate, advanced rectal, or cervical cancer who are about to receive radiation or chemoradiation. They must be in good enough health to participate (ECOG 0-2) and not have had certain prior treatments like long-term hormone therapy for prostate cancer or any chemotherapy. Pregnant women, those planning pregnancy, lactating women, individuals on strict diets such as keto or paleo, and those with a BMI under 21 are excluded.
What is being tested?
The study compares the effects of time-restricted eating (intermittent fasting) versus nutritional counseling on reducing side effects from radiation or chemoradiation treatment in patients with specific cancers. Researchers want to see if these dietary approaches can enhance the effectiveness of cancer treatments and lessen their adverse effects.
What are the potential side effects?
While this trial focuses on diet's impact rather than drugs', potential side effects may include hunger during fasting periods, possible changes in blood sugar levels which could affect diabetics' medication needs, and general discomfort associated with altering one's eating patterns.

Other Research
Common treatments for prostate cancer include androgen deprivation therapy (ADT) and radiation therapy. ADT lowers testosterone levels, which prostate cancer cells rely on for growth, thereby slowing disease progression. Radiation therapy destroys cancer cells by damaging their DNA. Emerging strategies like time-restricted eating, which alternates between fasting and non-fasting periods, may enhance the efficacy of radiation therapy and reduce its side effects by improving metabolic health and reducing inflammation. These mechanisms are important as they can potentially improve treatment outcomes and quality of life for prostate cancer patients.
