The known facultative predisposing factors for the development of angiosarcoma in the cases studied were: chronic lymphedema in three cases and postirradiation status in two cases
The known facultative predisposing factors for the development of angiosarcoma in the cases studied were: chronic lymphedema in three cases and postirradiation status in two cases. whereas sarcomas with high Fas-L expression show significantly reduced numbers of TILs. These results suggest that the Fas/Fas-L system may repress TIL invasion into angiosarcoma and by this may…
