据美国癌症协会估计,1986年美国有39,000女性死于原发性乳腺癌,123,000名乳癌新患者,年龄校正发生率14.9/100,000,虽然30%乳癌转移到卵巢,很多转移病灶仅在乳癌患者死后尸检时发现,但乳腺是卵巢癌转移的少见部位。随着卵巢癌治疗对局部控制及长期生存的改善,卵巢癌转移到乳腺的发生率可能有所提高。文献表明,乳腺外肿瘤转移到乳腺罕见,据临床观察,转移率为0.5～1.3%。连续1,000例恶性上皮性肿瘤的尸检中,转移到乳腺有50例(5%),36例来源于对侧乳腺,乳腺外肿瘤转移14例,2例(3%)由卵巢原发性肿瘤转移至乳腺。乳腺转移癌的实
According to the American Cancer Society, in 1986, 39,000 women died of primary breast cancer and 123,000 new breast cancer patients in the United States in 1986, with an age-adjusted incidence of 14.9 / 100,000. Although 30% of breast cancers metastasize to the ovary, many metastatic lesions are only death in breast cancer patients After the autopsy found, but the breast is a rare site of ovarian cancer metastasis. With the treatment of ovarian cancer on the local control and long-term survival improved, the incidence of ovarian cancer metastasis to the breast may be increased. The literature shows that extramammary tumor metastasis to the breast is rare, according to clinical observation, the transfer rate of 0.5 to 1.3%. In an autopsy of 1,000 consecutive malignant neoplastic tumors, 50 (5%) were transferred to the breast, 36 from the contralateral breast, 14 from the extrabronchial tumor, and 2 (3%) from the primary ovarian tumor To the breast.
