First of all, if your brother has not had a colonoscopy, how does the doctor know its colon cancer and not something else. Obviously there is something wrong, but a doctor, unless a biopsy was done, cannot make a definitive decision on whether something is colon cancer that has spread somewhere else or say, liver cancer that has spread. Granted, there are always the 'normal' cases, but as you will see, normal isn't always the case.
As for doctors or places to be treated, you can look up colorectal surgeons at this site:
http://www.fascrs.org/patients/find_surgeon/I would HIGHLY stress that you find a board certified colorectal surgeon. Many general surgeons can and do do the job but, particularly for a patient with other organs involved, I would most definately want to find a board certified surgeon. With regards to the oncologist, most oncs follow the same protocol - at least initially. The standard of care doesn't deviate much in the first and second lines of treatment. It's always good to have the patient get more than one opinion with both the surgeon and the onc. Since the onc will be much like a primary doctor for some time, make sure that your brother feels comfortable with him/her. You will want to make sure that your onc LISTENS to your brother and respects his opinions/wishes, etc. In addition, make sure that your brother feels comfortable with the oncology clinic as a whole. During his treatment and afterwards, your brother will be calling on them for many reasons and he needs to make sure that the nurses, staff as well as the doctor are reachable and approachable.
While the situation doesn't sound good to any of you right now, try not to imagine the worst case scenario right now. Your brother needs to wait for the biopsy which will tell him a lot about his tumor and how aggressive it may or may not be. The pathology report will shed a lot of information on his case. Please remember this. While the initial diagnosis and prognosis may very well not appear to be that good, how your brother responds to treatments will be the deciding factor in which direction he is able to go. Initially, your brother may or may not be told that he is not a surgical candidate but if he responds well, the whole situation could be reclassified. Don't be afraid to seek a second opinion, even in the midst of treatments. Many patients on this board have stuck with their oncologists yet read about others on this board who have had totally different treatments, opinions, etc., have sought out a different opinion from another doctor and have found that their situation changed overnight. Finally, and others may not agree with me on this, but don't let an oncologist tell your brother that he is not, for example, a surgical candidate or that he will need such and such specific surgery. Let the surgeon decide whether or not your brother is a surgical candidate and which type of surgery will or will not be feasible. On the same note, let the oncologist decide (and not the surgeon) which type of chemo to take, how long, etc. Just keep in mind that this happens frequently. So, let the surgeon do the surgical opinions/work, the rad onc (if he has one) do the rad onc treatments and the medical onc take on the responsibility for everything chemo related.
Good luck and please keep us informed of your brother's progress and situation.
