Extreme vomiting

My mom is diagnosed with recurrent Uterine papillary serous carcinoma, which is similar histology to the ovarian cancer. Her cancer now spreads to her abdomen and she is on Doxil chemo. She had only one treatment. But the consistent vomiting started 5 days after the chemo and has not stopped yet. She is in the hospital right now.
Everything she intakes whether liquid or solid comes out within minutes.
If anyone went through this, please share your experiences. What the doctors did to help you and how long did this last, etc…?
