Scientific Session of the Western Surgical Association. Portland, Ore (USA), 1996/11/20.
To evaluate the national treatment trends for the management of ductal carcinoma in situ as related to the individual characteristics ofpatients and to the reporting of demographics.
National Cancer Data Base review.
Patients (N=39 010) who were diagnosed as having ductal carcinoma in situ between 1985 and 1993.
Main Outcome Measures
Treatment principles, including the use of breast-preserving surgery, axillary lymph node dissection, and radiotherapy, as related to the following variables :
age, income level, and ethnicity of the patient ;
the tumor size, grade, and anatomical subsite ;
year of diagnosis ;
geographic location of treatment ;
and hospital type and caseload.
During the 8 years of analysis, the use of breast preservation therapy increased from 31% to 54%. Treatment selection varied to some degree with each of the variables examined.
Tumors with favorable sizes and grades were associated with increased rates of breast preservation and lower rates of axillary lymph node dissection and radiotherapy utilization.
Overall, only 45% of the patients who were treated with breast preservation received adjuvant radiotherapy.
However, during this study, radiotherapy utilization increased from 38% to 54%. Axillary lymph node dissection was performed in 49% of the patients with a 12% reduction in use over time. (...)
