Context: The management of breast cancer in older patients is challenging due to factors such as comorbidities, limited mobility, functional dependence, cognitive functions, and socioeconomic aspects. Data about the outcomes in elderly patients with breast cancer in our country are sparse.
Aims: The aim of this study was to evaluate and compare the clinical and pathological variables, treatment, and survival outcomes of elderly women (those of 70 years and above) with women under 50 years and those between the ages of 50 and 69 years treated at our center.
Subjects and methods: Prospectively collected clinical and pathological data from January 2007 to December 2014 were recorded and entered into OncoCollect™ software. Statistical analysis was done using Microsoft R Open software. Survival analysis was estimated using Kaplan-Meier curves.
Results: A total of 1226 Stage I-III breast cancer patients were treated between January 2007 and December 2014. Of these, 11.3% (139) were aged 70 years and above. Invasive ductal carcinoma was predominant and majority had Stage II disease and grade 1 tumors. Receptor positivity was observed in 79% of elderly patients and 9% had triple-negative disease. Primary hormone therapy was given to 7% of the patients and chemotherapy was administered to 12%. The 5-year overall survival for patients 70 years and older is 85%.
Conclusions: Elderly patients are more likely to have an indolent course with low grade and estrogen receptor-positive tumors. For healthy older women, treatment according to standard guidelines including surgery, chemotherapy, and radiation should be followed. However, for those who are unfit and cannot tolerate surgery, primary endocrine therapy is a suitable option.
