[The primary-multiple malignant tumors inpatients with mammary gland cancer].
Of 5073 patients with mammarial gland cancer (MGC) observed during 20 years of follow-up in 409 (8.1%) polyneoplasia was revealed. In 21 (5.1%) of 409 patients three polyorganic primary tumors and more were revealed. In 108 (26.4%) of them the primarily-multiple tumors were synchronous, in 301 (73.6%)--metachronous. Most frequently MGC occurred in conjunction with tumors of genital and digestive systems, which have the highest frequency in population. In the other organs polyneoplasia was revealed significantly rarely.
