Breast carcinoma: expected results with prevailing therapy

Area of Science:

• Oncology
• Medical Statistics

Background:

• Breast carcinoma diagnosis and treatment have evolved significantly.
• Understanding prognostic factors is crucial for patient care.

Purpose of the Study:

• To analyze survival rates of breast carcinoma patients based on age and stage at diagnosis.
• To compare survival trends with historical data.
• To develop predictive models for patient prognosis.

Main Methods:

• Retrospective analysis of computer-stored tumor registry data from Evanston Hospital (1973-1977).
• Inclusion of 560 evaluable breast carcinoma patients.
• Stratification of patients into age groups: less than or equal to 50 (LE 50) and greater than 50 (GT 50).
• Calculation of projected survival rates at 5 and 7 years.
• Statistical comparison of survival between age groups and stages.

Main Results:

• Overall 5-year survival was 8% and 7-year survival was 72%.
• Survival rates for patients LE 50 were comparable to those GT 50.
• Stage III patients GT 50 demonstrated significantly better survival than Stage III patients LE 50 (P < 0.001).
• A historical trend towards improved 5-year survival was observed.

Conclusions:

• Age is a significant prognostic factor, particularly for Stage III breast carcinoma.
• Prognosis can be predicted using age and stage at diagnosis.
• Findings contribute to understanding long-term breast carcinoma survival trends.
