As I noticed that you haven't yet received a reply to your post, I thought I might stop by and welcome you to our forum.
Hopefully, some of our friendly members will pop here soon to chat with you but also, feel free to join the conversations going on here. If you use the search engine from the left-hand side of the blue banner at the top of this page and insert 'Carcinosarcoma' it will show up previous posts which you might find useful.
