[Sparing and organ-saving operations in breast cancer].

The paper discusses the interim results of the use of organ-saving surgery for T1-2N0M0 breast cancer ("superficial" tumors not larger than 2.5 cm in diameter). Since 1985, two-hundred and twelve patients have been included into the study, of whom 105 underwent en bloc segmental resection with axillary lymph node dissection, whereas 107--modified mastectomy after Patey-Diasson. In the first group, local recurrence was observed in 4 (3.8%) patients and distant metastases--in two, whereas in the latter group, no recurrence was registered within four years of follow-up and distant metastases occurred in 4 (3.7%) cases. Three-year survival rates in the two groups were similar: 96.8 and 98.2%, respectively.
