Background: Breast reconstruction is currently offered on a more routine basis to patients after mastectomy for breast cancer. This paper analyzes the outcomes of breast cancer surgery, and the results and effects of breast reconstruction using free TRAM flaps.

Methods: A retrospective review of 75 consecutive patients who had free transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction after breast cancer surgery was performed. A total of 92 free TRAM flaps were performed on 75 patients in Victoria, British Columbia, from January 1992 to May 1999. Thirty-three patients (44%) underwent primary breast cancer surgery and an immediate reconstruction (7 bilateral and 27 unilateral) and 42 patients (56%) had delayed reconstruction (10 bilateral and 32 unilateral).

Results: Twenty- one patients (28%) had stage 0 disease, 20 (26.7%) had stage I disease, 17 (22.7%) had stage IIA disease, 12 (15%) had stage IIB disease, and 4 (5.3%) had stage IIIA disease. In 1 patient the stage of disease was unknown. The mean patient age was 49.4 years (range 33 to 73). Of the patients undergoing immediate reconstruction 3 had postoperative chemotherapy and 1 had postoperative radiotherapy. Three patients had combined chemoradiotherapy. In none of these cases was the adjuvant therapy delayed by the reconstructive surgery. Overall mean follow-up time from cancer diagnosis was 56.8 months and from the time of TRAM flap reconstruction, 36.7 months. To date, 5 recurrences have been detected (6.6%). Mean time between reconstruction and detection of recurrence was 22.8 months. Detection of recurrence was achieved clinically and was not impaired in any of the cases by the presence of the free flap. Patient satisfaction was assessed via a telephone survey, with 93% of patients pleased with the cosmetic results of their surgery.

Conclusions: For those patients with breast cancer requiring mastectomy, free TRAM flap reconstruction is a safe, cosmetically acceptable surgical alternative that impairs neither effective breast cancer surgery nor detection of recurrent disease.
