Patients with metastatic angiosarcoma undergoing chemotherapy, radiation, and/or
surgery experience a median progression free survival of less than 6 months and a
median overall survival of less than 12 months. Given the aggressive nature of
this cancer, angiosarcoma clinical responses to chemotherapy or targeted
therapeutics are generally very poor. Inhibition of beta adrenergic receptor
(?-AR) signaling has recently been shown to decrease angiosarcoma tumor cell
viability, abrogate tumor growth in mouse models, and decrease proliferation
rates in preclinical and clinical settings. In the current study we used cell and
animal tumor models to show that ?-AR antagonism abrogates mitogenic signaling
and reduces angiosarcoma tumor cell viability, and these molecular alterations
translated into patient tumors. We demonstrated that non-selective ?-AR
antagonists are superior to selective ?-AR antagonists at inhibiting angiosarcoma
cell viability. A prospective analysis of non- selective ?-AR antagonists in a
single arm clinical study of metastatic angiosarcoma patients revealed that
incorporation of either propranolol or carvedilol into patients' treatment
regimens leads to a median progression free and overall survival of 9 and 36
months, respectively. These data suggest that incorporation of non-selective ?-AR
antagonists into existing therapies against metastatic angiosarcoma can enhance
clinical outcomes.
