PURPOSE: The authors evaluated the relative risk of developing radiation-induced breast cancer (BC) in women treated with radiotherapy for Hodgkin's disease (HD) and analysed the imaging features of these breast neoplasms. MATERIALS AND METHODS: We retrospectively studied 54 women who had all undergone radiotherapy between 1980 and 2010 (median age, 36.6 years). Women aged ≤30 years were screened with clinical breast examination, ultrasound (US) and, if necessary, mammography; women >30 years had clinical breast examination, US and mammography. Three women underwent magnetic resonance (MR) imaging as well. RESULTS: Mammography detected seven invasive breast cancers in 6/54 women (11.1%). Median age at diagnosis was 26.1 years for HD and 42.4 for breast cancer. Breast cancer was diagnosed following a median latent period from radiotherapy of 15.1 years. Mean radiation dose was 37.6 Gy in women who developed breast cancer and 31.3 Gy in the other women. CONCLUSIONS: In our study, women who were exposed to radiation for HD had a 6.2-fold higher risk of developing breast cancer than the general population. In consideration of the young age and high breast density, women aged ≤30 years should be monitored by US and MR imaging; women aged >30 years should be monitored by US, mammography and, when necessary, MR imaging.

Abstract
PURPOSE: The authors evaluated the relative risk of developing radiation-induced breast cancer (BC) in women treated with radiotherapy for Hodgkin's disease (HD) and analysed the imaging features of these breast neoplasms. MATERIALS AND METHODS: We retrospectively studied 54 women who had all undergone radiotherapy between 1980 and 2010 (median age, 36.6 years). Women aged ≤30 years were screened with clinical breast examination, ultrasound (US) and, if necessary, mammography; women >30 years had clinical breast examination, US and mammography. Three women underwent magnetic resonance (MR) imaging as well. RESULTS: Mammography detected seven invasive breast cancers in 6/54 women (11.1%). Median age at diagnosis was 26.1 years for HD and 42.4 for breast cancer. Breast cancer was diagnosed following a median latent period from radiotherapy of 15.1 years. Mean radiation dose was 37.6 Gy in women who developed breast cancer and 31.3 Gy in the other women. CONCLUSIONS: In our study, women who were exposed to radiation for HD had a 6.2-fold higher risk of developing breast cancer than the general population. In consideration of the young age and high breast density, women aged ≤30 years should be monitored by US and MR imaging; women aged >30 years should be monitored by US, mammography and, when necessary, MR imaging.File | Dimensione | Formato | |
