Reconstruction of the radiated partial mastectomy defect with autogenous tissues.
As conservative surgery and radiation therapy have become accepted treatments for early-stage breast cancer, increasing attention has focused on the cosmetic results of this technique. When partial mastectomy--a term which encompasses a diversity of excisional techniques--is followed by radiation therapy, breast defects characterized by parenchymal loss, nipple-areola complex distortion, and cutaneous abnormalities can occur. From 1981 to 1990, eight patients sought reconstructive correction of a radiated partial mastectomy deformity. Patients were from 42 to 70 years of age (mean 49 years). All had breast cancer, except for one patient with diffuse and chronic breast abscesses. Six patients were reconstructed with latissimus dorsi flaps and two with rectus flaps. No patient underwent reconstruction sooner than 1 year after completion of radiation therapy; for the entire group, a mean of 2.6 years elapsed from completion of radiation therapy to flap reconstruction of the breast. Mammograms were obtained on all the breast cancer patients before and after the myocutaneous flap procedure. Follow-up extended from 1 to 9 years after reconstruction (mean 3.6 years) and included both physical examination and serial mammographic evaluations. Myocutaneous flap reconstruction with either latissimus or rectus flaps achieved an aesthetic improvement of the partial mastectomy deformity in all eight patients. Complications consisted only of seroma formation in two patients following latissimus flap reconstruction. Mammographic evaluation revealed fibrofatty degeneration of the soft tissues of both types of flaps, a change that occurs as early as 6 months after operation and appears as a radiolucent area. The feasibility of mammography as a screening adjunct for recurrent cancer in this group of patients is demonstrated. Advantages of this technique of autogenous tissue reconstruction are improvement of contour deformities associated with conservative surgery and radiation therapy, preservation of normal, sensate breast skin, enhancement of symmetry with the contralateral breast, and avoidance of a prosthesis.
