CME: Advanced systemic mastocytosis: from recognition to treatment

Activity Description / Statement of Need:

In this online, self-learning activity:

Systemic mastocytosis (SM) is a heterogeneous group of disorders caused by proliferation of abnormal clonal mastocytes, which accumulate in the skin and/or other organ systems. Mastocytosis, including SM, was reclassified as a distinct disease subtype in 2016, when the World Health Organization (WHO) removed mastocytosis from the myeloproliferative neoplasm (MPN) group. The WHO defines 5 SM subtypes, ranging from indolent SM, which is associated with mild symptoms and near-normal life expectancy, to mast cell leukemia, which is an aggressive hematologic malignancy associated with median survival of less than 1 year.

Target Audience:

HCPs including: hematology/oncology specialists, allergists, and clinical immunologists, dermatologists; physician assistants, nurse practitioners, and pharmacists who practice in those areas of specialty; and any other healthcare professionals with an interest in or who may clinically encounter patients with systemic mastocytosis.

Commercial Support Disclosure: This program is supported by an educational grant from Blueprint Medicines.

This activity is free of charge.
