Abstract
We experienced two cases in which breast cancer had recurred 25 or more years after the operation of breast cancer.
(Case 1) The patient is a female aged 73 years. She underwent Auchincloss operation for right breast cancer at age 47 years, and went on without recurrence, but an induration was found in her anterior chest wall 26 years after the operation. Fine-needle aspiration cytology of the induration was performed, and its malignancy was suspected. Thus, the tumor mass was surgically removed, and diagnosed as a local recurrence.
(Case 2) The patient is a female aged 65 years. She underwent Auchincloss operation for right breast cancer at age 40 years, and went on without recurrence, but lumbar pain appeared at age 65 years. Thus, she visited our Department. Bone metastasis, pleural membrane metastasis and right pleural effusion were observed on CT and bone scintigraphy, and no abnormal finding was found in other organs. Thus, this was diagnosed as the recurrence 25 years after the operation.
The recurrence 25 or more years after the operation of breast cancer is unusual. We survey them with reference to the previous reports.
