Hello, and I hope I can answer your question.
I am glad your sister-in-law is feeling better. The fact that she is pain free and able to eat is good evidence that she may not need to go into hospice yet, as hospice is for what is called
palliative care... Meaning they treat the symptoms of cancer like pain,
nausea, etc. but do not treat the cancer itself. Hospice is usually recommended when all treatments to control the spread of the cancer have failed and there is no further medical treatment that can reverse or improve her condition.
Ovarian cancer is the deadliest of GYN cancers. If your sister-in-law has it spread all over her stomach, as you say, the likelihood of her survival and recovery without further surgery or chemo is really impossible. The majority of women (65%) who are diagnosed at stage 3c (where it has spread through the abdominal cavity) die within 5 years of diagnosis.
I know that her family may believe that the doctors are wrong, but this is extremely unlikely if she has gotten care in the U.S., Europe or Canada in a reputable hospital. If they have access, they might want to get a 2nd opinion from a GYN
oncologist (a gynecologist who specialized in cancer) rather than a medical oncologist, if she hasn't seen one already. If she ever had surgery for her cancer, a GYN oncologist typically performs it, so she may have gotten that care already and failed.
There can sometimes be a "honeymoon period" with cancer where things don't get worse for a while. And as long as she feels well, it is perfectly fine to manage your sister-in-law at home. But she will die of this disease eventually and it will not go away by itself. Her belly is full of tumors. She has gotten infections probably from bacteria leaking into her blood from her blocked intestines. I apologize for being graphic, but I want you and her family to have a realistic view of what is actually happening to her.
So I hope she stays comfortable and feels good as long as possible. Her level of functioning might improve, but her cancer will not. She might get stronger if she can eat for a while but she will not recover. There are companies (in the U.S.) who have home hospice care, and even if she starts to suffer, she may be able to be treated at home and not have to go to a facility.
I hope this advice was helpful, and I wish you and your family support during this understandably difficult time. Ovarian cancer is a tragedy, and most people with the disease do not have a happy ending. I sincerely feel for your situation and wish there were more positive news that I could give you.
Best of luck to your sister-in-law, and you and her family.
Regards, Dr. Brown
