Evaluating post-mastectomy radiation for early breast cancer

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

Not applicable Interventional Tata Memorial Centre · NCT02992574

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.

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.

Who should consider this trial

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

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.

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 performed: 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.

Eligibility criteria

Inclusion Criteria:

* Women with unilateral pT1,2N0M0 breast cancer or multifocal breast cancer if largest discrete tumour at least 2cm or if the tumour area comprises multiple small adjacent foci of invasive carcinoma then overall maximum dimension taken. This must be greater than 2cm.

* Fit to receive adjuvant radiation +/- chemotherapy (if indicated) +/- hormonal therapy (if indicated)
* Written, informed consent

Exclusion Criteria:

* Any pTis/3/4, M1 patients
* Patients who have any pathologically involved axillary nodes (micro-metastasis may be allowed)
* Patients who have undergone neoadjuvant systemic therapy.
* Previous or concurrent malignancy other than non melanomatous skin cancer and carcinoma in situ of the cervix
* Pregnancy
