My husband (48) was diagnosed with Ewings Sarcoma in 2003. We got him into a clinical trial which consisted of high dose chemo, radiation and then having a resection of the chest wall because his tumor did not shrink. After being disease free for almost two years, we have just found out that his Ewings has returned and spread. While researching options for treatment, I came upon something called chemosensitivity testing, where they take a peice of the tumor and test chemo agents on it in a laboratory setting. We consulted our doctor and surprisingly our insurance has agreed to pay for the testing. My husband is scheduled for the biopsy next week. This is huge as we will be able to find out which chemo agents his tumor is resistant to, eliminating the trial and error of finding what drugs work.
