Dear BeverlyW,
Check with your mother-in-law's oncologist about setting up a MUGA Scan soon. It is used to measure the effectiveness of the heart. One of the side effects of Sutent is that it can cause damage to the heart. The MUGA Scan will set up a baseline for the heart and with a second scan latter on in the treatment the oncologish can measure weather there is any damage to your mother-in-law's heart caused by the Sutent. I was on Sutent 50 mg for 12 cycles before it stopped working in February. I just took my 3rd dose of Avastin. A lot of different, no side effects so far. It is given by IV every 3 weeks. Good luck!
Terry
