Purpose:
The Japanese Breast Cancer Society Clinical Practice Guidelines for Breast Cancer 2018 indicated that operation is the standard treatment for breast cancer in elderly patients. This study aimed to assess the safety and efficacy of surgery for elderly patients with breast cancer.
Methods:
Between April 2009 and November 2019, 545 patients underwent surgery in our hospital. The medical records of the elderly group(≥80 years, n=62)and the control(55-65 years, n=128)groups were compared and analyzed retrospectively.
Results:
The elderly group had more comorbidities(p<0.001)than those of the control group. Although no significant difference in the pathological stage was noted between the 2 groups, dermal infiltrations were more common(p=0.003)in the elderly group than those of the other, and 27% of them did not undergo any surgery to the axilla. This group experienced more post-surgery complications than those of the other; however, such complications did not extend beyond the duration of hospital stays. No difference in the recurrence rate between the groups was noted. In the elderly group, 64% died of comorbidities. The 3-year survival rate was 88.3% and 95.4% in the elderly and control groups, respectively(p=0.18).
Conclusions:
Our study revealed that surgery was safe for the management of breast cancer in elderly patients. However, their prognosis was poor owing to their comorbidities. Hence, careful therapy for their comorbidity is also important.
