What to expect progression of Liver Cancer

My mother died Jan, 2010 with lung cancer ( actually renal and cardiac shut down as effects of radiation on throat and chemo poisoning)
The day my mom was buried, my dad had a stroke. The day we put him into the hospital to find out what caused the stroke revealed he had lung and liver cancer. He received chemo for awhile, but now just wants it to be over so he can be with my mother.
He was referred to hospice when he stopped chemo - which is normally only referred to those who can expect to live 6 months or less.

We had many questions and were referred to the booklet noted below:

That site has a booklet that has answered many of our questions about what to expect in the last months of cancer.
