[Life expectancy of clinically occult breast cancer. Study of a comparative patient sample since 1975].
We have been observing 2 groups of 50 female patients with occult or clinical breast cancer each of whom was initially treated at the Gynaecologic Hospital of the University of Erlangen-Nürnberg between 1975 and 1978. During the follow-up period, 2 patients out of the group of occult cancer and 13 out of the group of clinical carcinoma died of their primary disease. Four women out of the group of occult cancer and 3 from the group of "clinical carcinoma" have developed recurrences. The differences in survival times according to Kaplan-Meier are immense, even if they are not significant owing to the small number of patients. But it is difficult to obtain and to evaluate larger groups of patients and longer follow-up periods due to the low percentage of occult cancer (7.7 to 10.5% only). There are 30 women out of the group of occult breast cancer living without relapse after an observation period up to 15 years. 27 patients out of the group of "clinical cancer" have not shown any evidence of recurrence up to now. This small difference after such a long follow-up period can be explained by the general life expectancy and by the age at initial treatment.
