New radiation technique aims to save implants in breast cancer patients
NCT ID NCT02086578
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a radiation method called multi-beam IMRT in 100 women with breast cancer who had implant reconstructions after mastectomy. The goal was to see if using 8-12 small radiation beams instead of the standard 2-5 could reduce implant failure and side effects. Results focused on lowering complications like capsular contracture and implant loss within 2-2.5 years after treatment.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Females who are age ≥ 18 years of age with a life expectancy estimated to be at least 2 years * Histologically-confirmed invasive breast cancer by MSKCC * Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 * Status post mastectomy with surgical assessment of axillary nodes * Immediate reconstruction with tissue expander (Group 2) or permanent implant (Group 1) prior to RT performed at MSKCC * If PMRT is recommended, the treatment fields will include the axillary, supraclavicular, and internal mammary nodes. Exclusion Criteria: * Absence of a breast reconstruction prior to RT (placement of tissue expander is sufficient for group 2) * Pregnant or breastfeeding. * Psychiatric or addictive disorders that would preclude obtaining informed consent or filling out Breast-Q© questionnaires. * Prior radiation therapy to the ipsilateral breast/nodes or thorax. * The criterias outlined above apply to the patients enrolled to meet the primary objective of the study. Additional criteria for patients in the cardiac substudy portion of the protocol are outlined in the protocol
