Oligometastatic breast cancer.

Metastatic breast cancer (MBC) is considered as incurable. The group of patients with oligometastatic disease (a few metastatic lesions and organs involved) apparently have better prognosis. It is claimed that, these patients could be treated with curative intent, and multidisciplinary aggressive approach should be considered. Despite the lack of strong data it is increasingly accepted in clinical practice. Currently, the appropriate candidate would be young woman with good performance status, low tumour burden with long disease-free interval. Because for them with already favorable nature of their disease, aggressive treatment has greater chances to improve survivals. Local ablative treatment (radiotherapy/surgery) has a crucial role in this setting. Available mainly from retrospective in nature long-term results are encouraging but need confirmation in prospective randomized studies. In this review, I discuss the definition of oligometastatic disease, its nature, currently available data and ongoing prospective randomized trials dedicated to oligometastatic breast cancer patients.
