What this trial studies

This observational study aims to identify immune alterations and predictive biomarkers in patients with operable breast and ovarian carcinoma. It focuses on understanding the mechanisms of immune response inhibition that contribute to tumor progression and resistance to treatments. By characterizing specific immune cell populations, the study seeks to uncover actionable targets for improving treatment efficacy in these cancers. The research will involve a cohort of female patients undergoing surgery for high-grade serous ovarian carcinoma or breast carcinoma.

Who should consider this trial

Good fit: Ideal candidates are female patients aged 18 and older with operable high-grade serous ovarian carcinoma or breast carcinoma.

Not a fit: Patients with constitutional BRCA1/2 mutations or those previously treated with immunomodulators may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for patients with breast and ovarian cancers by identifying new targets for immunotherapy.

How similar studies have performed: Other studies have shown promise in understanding immune mechanisms in cancer, but this specific approach is novel in its focus on operable breast and ovarian carcinoma.
