Recurrence of breast cancer. A retrospective study of 569 cases in clinical stages I-III.
Material comprising 569 cancer patients in clinical stages I-III is presented; recurrence, factors influencing recurrence and survival after recurrence have been studied. The 10-year recurrence rate for the whole material was 52%. Frequency of recurrence correlated with the clinical stage, the axillary biopsy finding and with the malignancy grade of infiltrating ductogenic carcinoma. The incidence ratio of local recurrence and distant metastases was 1:2; the most common site of the former being the chest wall and of the latter the viscera. After diagnosis of the first local recurrence, subsequent 5- and 10-year survival rates were 42% and 24% and after diagnosis of the first distant metastasis correspondingly 15% and 13%. Survival after the detection of axillary and supraclavicular metastases was better than after the detection of chest wall recurrences. Prognosis for distant metastases was best for soft tissue metastases and poorest for visceral and multiple metastases.
