Official title: Post-Mastectomy Radiation Therapy in High Risk, Node Negative Women With Early Breast Cancer (PMRT-NNBC)

Run by Tata Memorial Centre · NCT02992574 · Data updated 2026-11-12

This study tests if giving radiation after surgery can help women with early-stage breast cancer and certain high-risk factors avoid a return of their cancer.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are women with unilateral pT1,2N0M0 breast cancer or multifocal breast cancer with specific high-risk factors.

Probably not a fit

Patients with advanced breast cancer (pTis/3/4, M1) or those with positive axillary nodes are unlikely to benefit from this study.

What this trial studies

This trial investigates the effectiveness of post-mastectomy radiotherapy (PMRT) in women with early-stage breast cancer who have negative lymph nodes. It focuses on patients with specific high-risk factors that may increase their likelihood of recurrence despite having node-negative disease. The study aims to determine if PMRT can improve outcomes for these patients compared to those who do not receive radiation. Participants will undergo total mastectomy followed by the potential administration of adjuvant radiation therapy based on their individual risk profiles.

Why it matters

Potential benefit: If successful, this study could provide a new treatment approach that reduces recurrence rates and improves survival for women with early breast cancer who have negative lymph nodes but present with high-risk factors.

How similar studies have gone: Previous studies have shown varying outcomes for similar approaches, but this specific evaluation of PMRT in node-negative patients with high-risk factors is relatively novel.
