Description

Recently, breast cancers have increased in Japan. Sometimes, we meet women who develop breast cancer in both breasts. From 1990 to 2005, 618 women were treated for primary operable breast cancers in our hospital, 14 of them were developed bilateral primary operable breast cancers. 9 patients developed synchronous bilateral breast cancers, 5 patients developed metachronous. We compared them about age at operation, histology, hormone receptor status and survival. In synchronous cases, the mean age of diagnosis was about 57 years old. In metachronous cases, the mean age of diagnosis of the first cancer was about 61 years old. The mean age of the second cancer was about 70 years old. The mean interval between first cancer and second cancer was 115±44 months. In all cases most popular histologic type was scirrhous carcinoma. In our study, only 2 cases were matched histologic status in both. The lack of histologic correlation in bilateral cancers has been reported. Hormone receptor status was not matched in both breasts, too. Synchronous and metachronous bilateral breast cancers show almost the same for postoperative survival rate. Breasts are bilateral and symmetric organ. So we must try to follow closely for our patients of breast cancer.
