Popis: The purpose of this study was to quantify and describe nonmammary neoplasms (n-MN), particularly gynecological neoplasms, in a patient population previously diagnosed with breast cancer. Data were collected prospectively in our institutional review board-approved registry for patients diagnosed with infiltrating breast cancer or ductal carcinoma in situ. Patients who developed a second, n-MN were identified; neoplastic site, time to development after breast cancer, and clinical outcomes were recorded. FIGO stage was recorded for patients who developed a gynecological neoplasm. Synchronous bilateral breast cancer was defined as a second, contralateral diagnosis made within 12 months of the first and, similarly, synchronous n-MN were defined as those identified within 1 year of a breast cancer diagnosis. Outcome curves were generated using the method of Kaplan and Meier, and compared using the log-rank test. Of 4126 patients diagnosed with breast cancer, 3% developed a n-MN, the majority of which were nongynecological and asynchronous to the initial breast cancer diagnosis. Three percent of patients diagnosed with breast cancer were diagnosed with a second, n-MN. Among patients who developed a n-MN, most developed a nongynecological cancer more than 1 year after the initial breast cancer diagnosis, and their outcomes were significantly worse than those patients who did not develop a n-MN.
