Every resident/program has different views on it. The expectation for ours was that you got all the basic reading (staging/work-up/general management) done on your own time. Conference was to go over papers. So, if we were doing early stage breast/DCIS, we'd go over B06, Milan, B17, B24, a couple other ones with each resident presenting the papers with a written summary, comments, criticisms, and take-home points. During the presentations, an attending may ask general questions about breast cancer/DCIS. This was interdigitated with oral-examinations on that topic on the alternate week, or there would be a separate session for that with one or more residents being examined. Worked for us, had to do a lot on your own, but for a person like me - I could not sit there and passively listen to powerpoint presentations 1-2/week.
I sort of like how the UChicago program and I think Cleveland Clinic did this intensive weekly presentations, where one resident presents a case and another gets skewered about it by the faculty in front of a group. I bet it made the oral exam seem sort of easy.
