"""one of the difficulties is the striking range in the natural duration of cancer of the same site in a series of cases.�"""
Sutherland95 is basically saying that it is difficult to predict the prognosis of a cancer based on the site. Hence, doctors try to use other parameters like the histology and lymph node involvement to get an idea of the aggressiveness of a cancer.Your questions about your treatment have lead to my raising it for discussion in the Q & A section. Hope you don't mind. You might find the article mentioned there, """Prognosis in Cancer""" to be of interest.
