Regards your dad with leiomyo sarcoma in the iliac area I was diagnosed in nz I have leiomyosarcoma in the small bowel which is extremely rare I am told. My first indication of anything wrong was a burst bowel which resulted in major emergency surgery in late 2007.A resection of the small bowel was carried out and it was succesful but the bursting caused concern because of the nature of the disease. A recurrence occurred in april 2008 and I had further surgery in july 2008. There was a small mass on the abdominal wall and and five other sites. I made an outstanding recovery and had a further scan in january. I still do not have the results but feel fantastic and I can't imagine that I am sick it is crazy. I have not been offered any other treatment as I was told leiomyo is unresponsive to chemo or radiation. I need to know more about this as I would like some options if I could.
Good luck and good health to you
