Hope

Was wondering if someone can tell me where we are in our battle. My father was diagnosed with PC about 6 mos ago and was not able to have whipple because it was also in his liver. He has had about 3-4 rounds of chemo. No changes, which could be seen as good and bad. His last round of chemo really made him feel poorly. He isn't eating well as his appetite is not good and things just don't taste good. He is thinking of taking a break from the chemo for a bit. Is this wise? Is it common to do that? Wish there was more clarity to the situation. More, I guess something more to hold onto that would let us feel that all is well.
