Reconstruction and the radiated breast: Is there a role for implants?

The use of breast implants in irradiated patients is controversial. Recently, 39 irradiated implants were compared with 338 nonirradiated implants in 297 patients between January of 1975 and October of 1994 at The University of Texas M. D. Anderson Cancer Center. Tissue expanders and follow-up time of less than 6 months excluded patients from the study. Five groups of patients were identified. Group 1 consisted of 7 patients and 7 implants who received postoperative adjuvant radiotherapy after implant placement. Group 2 consisted of 5 patients and 7 implants who received preoperative adjuvant radiotherapy prior to implant placement. Groups 3 and 4 consisted of 2 and 12 patients (2 and 19 implants) placed beneath latissimus dorsi flaps who had postoperative and preoperative adjuvant radiotherapy, respectively. Group 5 contained 4 patients with 4 implants placed beneath a transverse rectus abdominis myocutaneous (TRAM) flap who had preoperative radiotherapy. All implants were placed submuscularly or beneath autogenous flaps. The average irradiated breast received 50 Gy.
