[Criteria of primary multiple bilateral tumors of mammary gland, their clinical significance in diagnosis of primary and metastatic tumors].
Clinical data and results of morphological investigation of the mammarial gland (MG) tumor in 158 women with bilateral affection are summarized. For diagnosis of primary bilateral MG tumors it is possible to use following criterions: absence of remote metastasizing and local recurrency of cancer, spread of the first metachronous or both synchronous tumors no more than of T1-2N0-1M0 stage, presence of nodular form of the MG cancer, localization of tumoral nodes in external hemispheres contralateral MG. In diagnosis of metastatic bilateral tumors may be used criteria, owing acceptable prognostical validity of negative result, presence of remote metastasizing (PVNR 95.2%), spread of the first metachronous or both synchronous tumors of T3-4N0-3M0-1 stage (PVNR 93.6%); infiltrating form of the bilateral MG cancer (PVNR 95.2%); revealing of tumor in contralateral MG during 2 years (PVNR 84.4%); much lower degree of differentiation of the second tumor (PVNR 77.4%).
