Hi,
Please realize that there is plenty of data that shows chemo can be curative for metatastes confined to regional lymph nodes. I know a couple of women personally who have been through this and are many years cancer free. Don't despair. I know of a woman who failed one chemo course but got total response to another.
If there is any other spread to organs like liver or lung the outlook is less positive, but even if that were so, there is still time to be shared with your mother. This is not an immediate death sentence but it's not an easy road either.
Get a good uro oncologist/specialist in the field involved if at all possible. Is your mother happy with her doctor and team, place of treatment? It sounds like she needs to hear something hopeful in order to encourage her to seek treatment.
There is no way to answer just 'how bad' things are and what to expect as that depends on what the scans show, what options are offered and what options are acceptable to your mother.
Is she in good general health, recovered from surgery?
And for the record, up until recently it was not always advised to have chemo before or after surgery even for stage III, and many people did fine. Seems to me it's becoming more and more common to advise chemo these last five years or so, because there is a true search on to improve long term survival rates for those who undergo bladder removal and some experts have come out with studies saying chemo will do this.
Have a look at WebCafe's "Tales from the Trenches", survivor stories for an idea of what others' experiences were like. Read the chemo section on the main site, as well as the metatcc.asp page for metastatic.
And of course feel free to ask anything, there are many here who have been or are going down a similar path as your mother and you. There are success stories, there are also stories that are not, we see it all.
I know the terror and pain of having a loved one be diagnosed with cancer- any cancer. It's horrible. But believe me, it becomes familiar after a while, if you can learn the territory it may help relieve some of the fear of the unknown.
Stats are easy to find it you want; I've read that up to 30% of those with local nodes involved are alive and cancer free 5 yrs later if total response to chemo is had.
I'm glad your mother is not second guessing her initial choice. Besides, as someone who is 'chemo naive' she will get a better response than if she'd already done it without knowing for sure it was actually needed. That's another way to look at it.
Take care,
Wendy
