Surgery is associated with lower morbidity and longer survival in elderly breast cancer patients over 80

As breast cancer is the most frequent cancer in the elderly with a peak incidence of 1 in 10 by the age of 80, it is important to establish optimum therapy in this group. We conducted a case note-based retrospective study of all elderly primary breast cancer patients aged 80 and above between 1992 and 2002. The type of treatment, complications, disease progression, recurrence, and overall survival were recorded. In all 110 patients aged 80 and above were treated for primary breast cancer, with 32 patients having advanced disease. Of these, 62 patients received primary endocrine treatment. 48 patients underwent surgery with 30 patients undergoing mastectomy. At follow-up, 34 patients suffered disease progression in the primary endocrine treatment group and three patients had local recurrence in the surgical group. The Kaplan-Meier analysis revealed significantly better survival in the surgical treatment group when compared with the primary endocrine treatment group, both in the early disease (n = 41; median survival: 71 months; compared to n = 37; median survival: 42 months; p = 0.0002) and the advanced disease (n = 7; median survival: 48 months; compared to n = 25; median survival: 36 months; p = 0.03). Prompt surgery and adjuvant treatment can decrease relapse and improve survival even in patients older than 80 years.
