Breast Cancer
St. Anthony’s Hospital
Cancer Registry Study 1987 - 2004

Breast cancer is the most common cancer seen in the St. Anthony’s Hospital Cancer Registry and accounts for 17.6% of all cases.  This study reviews the experience with all analytic cases of female breast cancer during the period 1987 through the end of 2004. The data was compared with the appropriate national data banks of the National Cancer Data Bank (NCDB) and NCI’s SEER program.

There were 2,323 cases, with 93% white and 6% African-American (nationally these numbers are 83% and 9%). The number of cases has been increasing over the years of the study (Figure 1). The median age was 68 with 15.1% younger than 50. The age distribution and comparison is noted in Figures 2 and  3.

The 5year relative survival was 93% and 10 year relative survival was 80%. The stage distribution (figure 4) and survival (figure 5) compare favorably with national data. The percent of patients diagnosed at an early stage has remained stable (figure 6) which reflects on screening. The use of breast conservation in early stages has increased with time (figure 7.)

The stage distribution, survival and treatment compare favorably with national data in the management of breast cancer.
