The clonogenic activity of a previously purified 43 kDa EGF-related protein (16) was estimated in the urine of breast cancer patients. Increase of activity was statistically significant in lymph node-positive patients, in a group of patients with larger carcinomas, with accelerated tumor growth, in premenopausal patients and younger age and in estrogen receptor negative patients. In 31 patients the activity was estimated during polychemotherapy before surgery. Differences between the values at the begin and the end of treatment were compared between all groups by the Kruskal-Wallis test (p = 0.02). Patients with progressive disease showed increasing activities (mean values from 315 to 811) while in those with complete remission activity decreased (from 449 to 213). Partial- and non responders showed no change. In a long-term follow-up study with 25 patients the pre- and postoperative activities were estimated. In 17 of 18 patients who had no local recurrence or metastasis the activity declined after surgery, whereas in 6 of 7 patients who died, activity increased 2-5 fold prior to death. A life table analysis with a total of 101 patients revealed a trend to shorter survival in the group with higher activity (p = 0.042). These observations suggest a role for the EGF-like growth factor activity in the expression of the malignant phenotype and may have significance for breast cancer diagnosis and prognosis.
