Impact of Immediate Reconstruction on the Local Recurrence of Breast Cancer After Mastectomy

In Brief The incidence of local recurrence of breast cancer in women who underwent mastectomy with or without reconstruction was examined. All female mastectomy patients were followed-up in a 10-year retrospective review. Groups consisted of patients who had mastectomy, mastectomy with immediate reconstruction, or delayed reconstruction. Reconstruction was performed using prostheses, latissimus dorsi musculocutaneous flaps with or without implants, or transverse rectus abdominis musculocutaneous flaps. Charts were reviewed for local breast cancer recurrence. Statistical analysis was performed using Pearson's chi-square and analysis of variance. Of the 1,444 mastectomies performed from 1988 to 1997, 1,262 breasts (87%) were not reconstructed, 182 (13%) were reconstructed, 158 (87%) were immediately reconstructed, and 24 (13%) were reconstructed later. There were no recurrences in the delayed reconstruction group, two recurrences (1.3%) in the immediate reconstruction group, and nine recurrences (0.7%) in the mastectomy without reconstruction group (p = 0.746). Analyses of an additional time period from 1992 to 2000 yielded similar results. There is little relationship between local recurrence of breast cancer after mastectomy and reconstruction. A 10-year retrospective review of 1,444 mastectomies, 182 of which underwent reconstruction, demonstrated 1.3% recurrences in the immediately reconstructed breasts, 0.7% recurrences in the unreconstructed, and 0% in delayed reconstructions. There was no statistically significant difference among these three groups, although the subgroup of stage III disease demonstrated an increased rate of local recurrence for women who underwent immediate reconstruction.
