Purpose. Despite advances in endocrine therapy (ET), metastatic estrogen receptor positive breast cancer (BrCA) remains incurable. Though the mechanisms of resistance to ET have been studied extensively, the anatomic pattern of disease progression remains poorly characterized. The purpose of this study was to characterize the pattern of progression for patients receiving ET for metastatic BrCA. Methods. The records of 108 patients with metastatic BrCA who progressed on ET were reviewed. Progression was characterized as follows: diffuse progression, progression in greater than 3 sites; oligoprogression, progression in fewer than 3 sites with prior diffuse metastases; and oligometastatic disease with progression, progression in 3 or fewer sites with prior limited metastases. Results. Seventy-four patients (69%) displayed only diffuse disease progression. Conversely, 23 patients (21%) displayed oligoprogression and 11 patients (10%) displayed oligometastases with progression at least once in their disease course. Further analysis of the patients with oligoprogression suggested that in 14 patients the sites of progression would have been amenable to local therapy. Conclusion. Oligoprogressive disease occurs in a significant subset of patients with metastatic BrCA treated with ET. These patients with oligoprogressive disease may be eligible for local therapy, potentially obviating the need to change of systemic therapy.

Abstract Disease recurrence (locoregional, distant) exerts a significant clinical impact on the survival of estrogen receptor–positive breast cancer patients. Many of these recurrences occur late, more than 5 years after original diagnosis, and represent a major obstacle to the effective treatment of this disease. Indeed, methods to identify patients at risk of late recurrence and therapeutic strategies designed to avert or treat these recurrences are lacking. Therefore, an international workshop was convened in Toronto, Canada, in February 2018 to review the current understanding of late recurrence and to identify critical issues that require future study. In this article, the major issues surrounding late recurrence are defined and current approaches that may be applicable to this challenge are discussed. Specifically, diagnostic tests with potential utility in late-recurrence prediction are described as well as a variety of patient-related factors that may influence recurrence risk. Clinical and therapeutic approaches are also reviewed, with a focus on patient surveillance and the implementation of extended endocrine therapy in the context of late-recurrence prevention. Understanding and treating late recurrence in estrogen receptor–positive breast cancer is a major unmet clinical need. A concerted effort of basic and clinical research is required to confront late recurrence and improve disease management and patient survival.
