Comparing concurrent and sequential chemotherapy with radiation for breast cancer

Official title: Phase III Randomized Controlled Trial of Sequential Chemotherapy and Radiotherapy Versus Concurrent Chemoradiotherapy in Adjuvant Treatment of Breast Cancer (CONCERT)

Run by Tata Memorial Centre · NCT06926543 · Data updated 2026-11-12

This study is testing whether getting chemotherapy and radiation at the same time works better than getting them one after the other for people with stage IIB-III breast cancer.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 with pathologically confirmed stage IIB-III invasive breast cancer who are fit for adjuvant chemotherapy and radiotherapy.

Probably not a fit

Patients with hypersensitivity to taxanes, those who have received prior chemotherapy, or those with certain anatomical factors may not benefit from this study.

What this trial studies

This clinical research aims to determine the effectiveness of concurrent chemotherapy and radiation therapy compared to sequential chemotherapy followed by radiation therapy in patients with stage IIB-III breast cancer. The study will evaluate disease-free survival rates, the impact on quality of life, side effects such as lymphoedema, and the financial costs associated with each treatment approach. Participants will receive standard chemotherapy and radiation therapy over a specified period, with follow-up assessments to monitor outcomes.

Why it matters

Potential benefit: If successful, this study could provide insights into the most effective treatment regimen for improving survival and quality of life in breast cancer patients.

How similar studies have gone: Other studies have explored similar approaches in breast cancer treatment, indicating potential for success, though this specific comparison may be novel.
