Propranolol in Angiosarcoma

Study Overview
=================
Brief Summary
-----------------
This is a window opportunity study of propranolol in patients with angiosarcoma. The aim of this study is to prospectively evaluate the activity of propranolol in the clinical setting as monotherapy, where the neoadjuvant setting provides a good opportunity to rapidly evaluate both the clinical response and histological response, without a significant delay in anti-cancer treatment.

Detailed Description
-----------------
A pilot neoadjuvant window of opportunity study will be performed to explore the activity of propranolol monotherapy in angiosarcoma. The study consists of a single arm. Propranolol will be administred as monotherapy in a dose of 40-80 mg 2-3 times a day, if tolerated. When patients are diagnosed, standard anti-cancer treatment will be scheduled in 6 weeks while propranolol treatment can start immediately after diagnosis and will be continued until the day the standard anti-cancer treatment is started. The duration of treatment will therefore be 3-6 weeks.
