Suffering From Cancer, Could My Mother Go Into Renal Fail, Sepsis Or Total Organ Failure?

Hi, my aunt is 68 currently gone through 4 round of chemo, for cancer in chest, liver and stomach. Her pep scan came back clear last week. She is now in icu with bp 60/ 40, renal out put down and catheter in now. An arterial line has gone in to give her more drugs, she is hyper pyrexial. She has 2 infections, uti and chest. She is very ill and I'm doing by best to keep my mother upbeat but honestly could she go into renal fail utter, sepsis or total organ failure?
