Answer

Patients with aggressive systemic mastocytosis have disease-related organ dysfunction; interferon-alfa (with or without corticosteroids) can control dermatological, hematological, GI, skeletal, and mediator-release symptoms, but may be poorly tolerated. Cladribine has broad therapeutic activity, particularly when rapid debulking is indicated; the main toxicity is myelosuppression. Imatinib has a therapeutic role in the presence of an imatinib-sensitive KIT mutation or in patients with unmutated KITD816. [41]
