I have a feeling that nearly everyone who has been treated for bone sarcoma has used some of the medications that are included in this lawsuit.
http://www.awptrack2settlement.com/index.htmAs far as I can tell, anyone in the US who has paid all or part of the cost of the drugs included qualifies to sign up to be a part of the suit. The dates go back to 1991, so if you were treated since then, you can join.
