Breast-conserving therapy is widely accepted as an appropriate method of primary treatment of T1 and T2 breast cancers that measure up to 5 cm. For safe and cosmetically acceptable breast-conserving therapy in patients with larger breast cancers, the tumor volume has to be reduced preoperatively, and lost tissue volume should be replaced after wide local excision. In 1993, the authors’ group reported encouraging short-term results of a combination of preoperative radiotherapy, breast-conserving surgery, and immediate tissue replacement by myocutaneous (myosubcutaneous) latissimus dorsi flap transplantation in patients with relatively large T2 and T3 breast cancers. To evaluate the long-term oncologic local control and cosmetic outcome of this treatment modality, the authors studied the results obtained in 20 patients after a minimum follow-up of 5 years. The local control rate was 0.95, as locoregional recurrence was observed in one patient who refused adjuvant chemotherapy. Both the observed 5-year survival (0.75) and the actuarial 10-year survival (0.60) in the authors’ series equaled that of more radical surgical therapy. The cosmetic outcome compared with that obtained by conventional breast-conserving therapy modalities for small breast cancers. In general, patient assessment of cosmetic outcome (2.8 of 3) was higher than the assessment of a professional panel (6.3 of 10). Of six criteria providing a detailed description of the cosmesis of the reconstructed breast and donor area, the symmetry and shape of the reconstructed breast were felt to be most important by the patients and professionals alike. The authors conclude that breast-conserving therapy combining preoperative irradiation and immediate myocutaneous (myosubcutaneous) latissimus dorsi flap reconstruction is an oncologically safe and cosmetically rewarding but logistically straining modality of treatment of relatively large T2 and T3 breast cancers.
