NeoRad Breast Cancer Study (NeoRad)

May 5, 2025 updated by: Bielefeld University

Preoperative Radiotherapy Versus Postoperative Radiotherapy After Neoadjuvant Chemotherapy ("NeoRad") in High-risk Breast Cancer: a Prospektiv, Randomized, International Multicenter Phase III Trial

The NEORAD trial tests whether preoperative radiotherapy results in an improved DFS and less radiation induced late effect compared to postoperative radiotherapy in higher risk breast cancer after NACT.

Study Overview

Detailed Description

The standard of care for high-risk breast cancer consists of neoadjuvant chemotherapy and surgery followed by postoperative whole breast/chest wall irradiation+/- an additional boost (= irradiation restricted to the tumour bed in the case of breast-conserving therapy). In case of lymph node involvement in most patients require additional radiation of the regional lymph nodes. Adjuvant radiotherapy significantly reduces ipsilateral breast cancer recurrences, breast cancer specific mortality, and overall mortality. The optimal time of radiotherapy in patients, who are candidates for neoadjuvant chemotherapy (NACT) has never been addressed in a randomised controlled trial.

The Study Chairman of the NEORAD trial is Prof. Dr. med. Christiane Matuschek. The deputies of the Study Chairman are Prof. Dr. med. Wilfried Budach and Prof. Dr. med. Tanja Fehm.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
disease free survival (DFS):
Time Frame: 6 to 10 years

Time interval in which the patient does not show any signs or symptoms of the treated cancer (local or regional recurrence, distant metastases, or death of any cause) beginning after randomisation to a study arm.

This is a way to measure how well the new treatment is working.

6 to 10 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
local recurrence rate [in affected breast] (LR)
Time Frame: 6 to 10 years
Rate of cancer that has recurred at the same location as the primary cancer. This is a way to measure how well the new treatment is working.
6 to 10 years
locoregional recurrence rate (LRR)
Time Frame: 6 to 10 years

Rate of new cancer at any locations (regional lymph nodes, chest wall/mastectomy site) on side which was previously affected by the primary cancer.

This is a way to measure how well the new treatment is working.

6 to 10 years
disease metastases free survival (DMFS)
Time Frame: 6 to 10 years

Time interval beginning after randomisation in which the patient survives and the cancer has not metastasized.

This is a way to measure how well the new treatment is working.

6 to 10 years
overall survival (OS)
Time Frame: 6 to 10 years

Length of time beginning after randomisation in the study that the patient survives.

This is a way to measure how well the new treatment is working.

6 to 10 years
disease specific survival (DSS)
Time Frame: 6 to 10 years

Length of time from the beginning of the study after randomisation in a study arm that the patient survives the specific cancer.

This is a way to measure how well the new treatment is working.

6 to 10 years
Assesment of cosmetic results by the physicians and the patient using a 5 point Scoring System*
Time Frame: 6 to 10 years

A grading scale is provided for cosmetic results (5 Point Scoring System):

E0 Excellent aesthetic result: At first sight no visible therapy sequellae. Both breasts have a similar appearance E1 Good: minimal changes in pigmentation, a visible scar, localized teleangieectasia.

E2 Moderate: marked sequellae with a clear deformation of the breast contour, nipple displacement, or marked skin changes, but yet "acceptable".

E3 Bad: severe retraction or fibrosis, severe teleangiectasia. E4 Complications: skin necrosis

6 to 10 years
Assesment of cosmetic results by the physicians using breast retraction assessment-Score (BRA Score)*
Time Frame: 6 to 10 years
*The BRA Score measures breast symmetry of the treated breast in comparison to the untreated breast. The average in the general population is 1.2 cm. A higher BRA score is worse. A BRA score of 0 cm is optimal.
6 to 10 years
Measurement of the quality of life (QOL): functional scale
Time Frame: 6 to 10 years
QoL will be assessed by EORTC (European Organisation for Research and Treatment of Cancer) QLQ-C30 questionnaires for overall QoL and EORTC QLQ-BR23 for breast-specific QoL. The QLQ-C30 consists of 30 questions categorized in functional and symptom-specific scales and provides a global score through two general questions concerning health and quality of life. QLQ-BR23 is a standard instrument for measuring QoL in patients with breast cancer. The questionnaire has 23 items with four possible answers each (not at all, a little, quite a bit, very much). Results are reported using functional scales (e.g. body image, sexual functioning) and symptom-related items (e.g. systemic therapy side effects, breast symptoms). It is also common practice to classify the summary scores into four distinct categories with functional scales (0-25 bad; 26-50 moderate; 51-75 good; 76-100 excellent) and symptom-related scales.

A grading scale is provided for plexopathia of brachial plexus on the irradiated side higher than Grade 1 (0= "not present", 1= "Aysmptomatic; clinical or diagnostic observations only; intervention not indicated", 2= "Moderate symptoms; limiting instrumental ADL*", 3= "Severe symptoms, limiting self care ADL") using common toxicity criteria for adverse events CTCAE, version 5.0

*ADL = activities of daily living

6 to 10 years
Assessment of treatment-related toxicity measured by the physicians using standardized common toxicity criteria for adverse events CTCAE, version 5.0.
Time Frame: 6 to 10 years
