What this trial studies

This pilot study aims to assess adherence to oral therapies in patients with inoperable advanced breast and prostate cancers. It will involve 200 participants who will complete self-questionnaires regarding their adherence to treatment, either at the clinic or at home within 10 days of enrollment. Blood samples will be collected on Day 0 to measure various biological markers related to their condition. The study focuses on patients who have been on oral anticancer medications for at least three months and have a performance status of 3 or less.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with inoperable advanced breast or prostate cancer who have been on oral therapies for at least three months.

Not a fit: Patients with early-stage cancers or those undergoing intravenous chemotherapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve understanding of treatment adherence, potentially leading to better management strategies for patients with advanced cancers.

How similar studies have performed: While there have been studies on treatment adherence in cancer patients, this specific approach focusing on advanced breast and prostate cancers is relatively novel.
