Leiomyosarcoma

I am going on 30 years this July with having Leiomyosarcoma.  I have had 2/3 of stomach removed, chemo, full hysterectomy, took gleevec, and just finished taking sutent.  The tumors are still growing and the dr. told me last week that they have run out of things to try.  I had contacted Cancer Treatment Center of America and am waiting to go and see them.  I would like to try natural remedies, being that pills and chemo hasn't worked, any suggestions?  Also has anyone gone to CTCA, and have they had any luck with them?  Thank you, and God Bless
