Factors determining prognosis in stage T1.2NoMo breast cancer

From study of data on 5- and 10-year survivals of 560 patients who underwent operation for breast cancer in stage T1.2NoMo, the authors determined the most significant prognostic factors. These were the histological form of the tumor and the degree of invasion into the adjoining tissues. The percentage of each studied factor was determined by mathematical analysis, which allowed the individual prognosis for each patient to be made and treatment planned accordingly.
