Take a deep breath. There are lots of treatments for this cancer. I also have a Grade 3 with a Ki67 of 38%. I did the CAPTEM oral chemotherapy combination. I had very few side effects except the dose was lowered because of low platelets. I had shrinkage after 3 months and then no change after 3 more months. So then they will give you a break and stop the chemo. I have now been off the chemo for 6 months with cancer stable. I do do Octrotide shots as I have functional Small bowel net with stage 4 Mets to bone and liver. I have felt fine throughout and continue with normal activity. Your husband will do great!
