My 75-year-old father was recently diagnosed with a localized malignant sarcomatoid, stage III, high grade in the pleura with chest wall attachment. He had surgical resection of the tumor; however, they could not resect all of it. He begins radiation treatments next week, 7 weeks, 5 days per week. We have been told this is a very rare cancer.
What is the prognosis this type of cancer or overall life expectancy? Are there other treatment options out there if radiation does not work.
