Patient-Reported Outcome and Safety Between Preoperative and Postmastectomy Radiotherapy in DIEP Flap Reconstruction (CAPPELLA)

November 21, 2024 updated by: Jiong Wu, Fudan University

Comparison of Patient-Reported Outcome and Safety Outcomes Between Preoperative and Postmastectomy Radiotherapy in Breast Cancer Patients with Reconstruction of DIEP Flap: a Multicenter，Prospective，Open-label，Randomized Controlled Trial

This study is the first prospective randomized study assessing the patient-reported outcomes and safety outcomes between preoperative and postmastectomy radiotherapy in locally advanced breast cancer patients with immediate reconstruction of deep inferior epigastric perforator(DIEP) flap. Radiotherapy before mastectomy and autologous free-flap breast reconstruction can avoid adverse radiation effects on healthy donor tissues and delays to adjuvant radiotherapy. We aimed to explore the feasibility of preoperative radiotherapy followed by DIEP flap reconstruction in patients with breast cancer requiring mastectomy.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No
