NCT06640959

Brief Summary

In the UK over 22,000 people undergo pelvic radiotherapy treatment per year, for several types of cancers including prostate cancer. The investigators want to investigate whether there are any differences in the bacteria in the bowel in patients with prostate cancer and whether these change during treatment. The aim of this study is to analyse the bacteria from the stool of patients undergoing radiotherapy for prostate cancer. The investigators will also look for any changes in the urine, blood and using rectal swabs that might be a surrogate for what is happening in the gut at the same time. They will collect food frequency/ food diary information for each patient alongside health questionnaires. The investigators aim to recruit approximately 50 patients diagnosed with prostate cancer due to undergo radiotherapy over a two year period. Patients will be recruited across 2 sites (Rosemere Cancer Centre, Lancashire Teaching Hospitals Trust and The Christie NHS Foundation Trust).

Outcome Measures

Primary Outcomes (1)

  • Feasibility of obtaining longitudinal blood, urine and stool samples

    Feasibility of obtaining longitudinal blood, urine and stool samples from patients with newly diagnosed prostate cancer undergoing standard of care radiotherapy. Samples will be collected at baseline (prior to the start of radiotherapy), weekly during radiotherapy for 4 weeks, 6-8 weeks and 12 from the start of radiotherapy, and at 6-month and 12-month follow-up appointments.

    From enrolment until 12 months post treatment

Interventions

Samples will be collected (blood, urine, stool and optional rectal swab) at baseline (prior to the start of radiotherapy), weekly during radiotherapy for 4 weeks, 6-8 weeks and 12 weeks from start of radiotherapy, and at 6-month and 12-month follow-up appointments
