Hormono-metabolic status was assayed before and after month 6, 12, 24, 36, 48, 54 and 60 of therapy in 72 patients with receptor-positive tumors of the breast who completed 5 years of adjuvant tamoxifen (20 mg/24 hrs) or letrozole (2.5 mg/24 hrs). Eleven patients were not followed up, 11 relapsed and had metastases while 50 completed therapy. Significant fall in body mass (Ketle's index), in C-peptide concentration after an insignificant rise and C-peptide/insulin ratio 129 min after glucose loading, low basal blood level of estradiol as well as stable estradiolemia throughout treatment were characteristic of cases of pre-treatment recurrence and metastastic spread. Insulin resistance status, basal serum-estradiol level and fasting its course of development during hormonotherapy should be the subject of further research in criteria for adjuvant hormonotherapy efficacy.
