Aims and background: The incidence of breast cancer increases with advancing age and in clinical practice approximately 50% of new cases occur in women over the age of 65 years. Although breast cancer in elderly patients presents more favorable biological characteristics than similar-stage cancer in younger women, disease control still remains uncertain and is becoming a major health problem.
Patients and methods: Between 1984 and 2006, 133 patients aged over 65 with operable breast cancer underwent surgical treatment. Patients with ductal or lobular carcinoma in situ, bilateral breast cancer or a previous malignancy were excluded. The mean age was 72.8 years (range, 66-89). Breast-conserving surgery was performed in patients with early breast cancer (T1, T2 < 2.5 cm), while most patients with advanced tumors (T2 >2.5 cm, T3, T4) were treated by modified radical mastectomy.
Results: The pathological stage was I in 44, IIA in 54, IIB in 18, IIIA in 10 and IIIB in 7 patients. Postoperative complications occurred in 13 patients (9%); there were no postoperative deaths. Eighty-nine patients underwent adjuvant therapy (chemotherapy, hormonal therapy). After a median follow-up of 96 months (range, 5-266), disease progression was observed in 21 patients (15.8%). The overall mortality from breast cancer was 11%, whereas the cancer-unrelated mortality was 9%.
Conclusion: There is no evidence that breast cancer has a more favorable prognosis in the elderly and surgical procedures should be carried out as has been established in younger women. At present, elderly patients are much less likely to be entered into randomized clinical trials and are often undertreated. However, in the absence of serious comorbid disease, they are able to withstand standard multimodal treatment options as well as do younger patients.
