<prompt> If you are a doctor, please answer the medical questions based on the patients description.My husband has glioblastoma stage iv. He had surgery in Aug and they removed 98 of turmor, but even with that they said he would have 4 to 14 months if we did a course of radiation and chemo. We are thru that now...but I am seeing he deteriorating quite quickly all of a sudden and I am wondering how I will know when we are near the end?  <response>: Hi, I understand all of your concerns, and it is needed chemo radiotherapy through the course of the disease. During this time there are ups and downs of his general condition, but there will be a time when he keeps deteriorating. Through all this I would have preferred for you to have some medical assistance helping you through it. I dont know if this helped, please feel free for any other question.
