Breast reconstruction in previously irradiated patients using tissue expanders and implants: a potentially...

There exists a paucity of definitive information on the suitability of implant reconstructions in previously irradiated breast cancer patients. This controversial topic prompted a review of our prosthetic reconstructions in this select group of patients. A retrospective study of patients treated between 1976 and 1993 with lumpectomy and radiation therapy for early breast cancer revealed 67 patients with local recurrences. Nine of these patients (10 breasts) underwent a two-stage prosthetic reconstruction following a salvage mastectomy. The average age was 47.9 years. The mean dose of irradiation was 6,070 cGy. The average interval from radiation therapy to placement of a tissue expander was 4.6 years. In one patient (10%) the tissue expander extruded. The average follow-up for 8 patients (9 breasts) who underwent exchange to a permanent prosthesis was 5.1 years. In four reconstructions (40%) there was an uneventful postoperative course. Two cases (20%) were difficult to expand and the final result lacked projection. One patient (10%) developed an infection requiring removal of the permanent prosthesis. Two patients (20%) developed Baker class III or IV capsular contractures. Overall, in our group of 10 implant reconstructions, 60% of the patients resulted in either a complication or an unfavorable result.
