Abstract
The development of ultimate visceral metastases and the visceral metastases-free time interval was evaluated in patients with breast carcinoma bearing bone-only metastases. Ninety patients were identified and were subdivided into three groups according to the anatomic distribution of osseous lesions: group A with osseous involvement cranial to the lumbosacral junction, group B caudal to this, and group C with lesions in both areas. The purpose of this subdivision was to evaluate if there is any correlation between bone-metastases distribution and probability of developing visceral lesions. All patients received systemic therapy consisting of hormonal therapy, chemotherapy or both. The median survival for the whole group was 28 months, whereas it was 33, 43 and 26 months for patients in groups A, B and C, respectively (p=NS). No differences in subsequent visceral involvement and visceral-free time interval were observed among the three groups of patients regardless of tumor burden. In conclusion, our analyses did not show significant differences in the incidence of visceral metastases, visceral metastases-free time interval and overall survival in patients with breast cancer with bone-only lesions independently of anatomic distribution.
