From: Histone deacetylase inhibition sensitizes osteosarcoma to heavy ion radiotherapy
Density of microvessels is significantly reduced in osteosarcoma after combination treatment. Xenografts were treated with DMSO (control), suberoylanilide hydroxamic acid (SAHA), irradiation (HIT) or HIT and SAHA. The density of microvessels was reduced in tumors of all treatment groups at all investigation time points. Tumors treated with HIT and SAHA showed a significant (*) lower vascularization compared to tumors treated with HIT from day 24 on and the lowest vascularization at all
