Immediate and late follow—up results of oncoplastic operations, performed in 75 patients, suffering mammary gland cancer (MGC), including in 22—a delayed, and in 53—primary reconstruction of the breast, were analyzed. In 66 patients musculo— cutaneous flaps on nutrient pedicle, taken up from the back and abdominal wall tissues, with underlying mammary gland endoprosthesis,were applied as a transplant. Ductal invasive MGC was diagnosed in 70 patients, invasive lobular one — in 5. After delayed reconstruction of the breast 81.8% patients have survived five years, and after primary reconstruction — 73.6%. Performance of oncoplastic operations in patients, suffering MGC, have permitted to achieve satisfactory immediate and late follow—up results of treatment, it constitutes essential element in complex of rehabilitation measures after performance of radical mastectomy.
