[Prognostic value of estradiol and progesterone receptors in stage I and II breast cancer with an adjuvant treatment].

Forty-seven stage T1, 225 stage T2, treated from January 1977 to December 1982 were studied. The median followup is 31 months (18-92) and the median age 57.5 years (26-92). On the 247 axillary clearances performed, there were 53% N- and 47% N+. The dextran coal method was used for the receptors dosage with R 2858 as ligand for estradiol and R 5020 for progesterone: positivity threshold was set at 10 fmoles. The RE+/RP+ group represents 40%, the RE+/RP- group 30%, the RE-/RP- group 7%, the RE-/RP- group 23%. The radio-surgical combination was systematic, with or without conservative treatment, followed by an adjuvant chemotherapy (15%), an hormonotherapy (34%), a chemohormonoprophylaxy (23%), within a protocol balancing the systemic treatment according to the following poor prognosis factors: axillary clearance positivity, grade 3 SBR, cytological grade 3. The crude actuarial survival is 96 +/- 4% (RE+ RP+); 73 +/- 15% (RE+ RP-); 78 +/- 12% (RE- RP-) and the disease-free survival was 84 +/- 9% (RE+ RP+); 68 +/- 15% (RE+ RP-), 67 +/- 14% (RE- RP-) with a significant difference between RE+ RP+ and RE+ RP- (P less than 10(-3)) and RE+ RP+ and RE- RP- (P less than 10(-5)). The crude actuarial survival and the disease free survival are studied according to menopausal status, Scarff-Bloom grade, and N+/N- axillary status. For N- patients, there is no significant difference for the disease-free survival, 84 +/- 14% (RE+ RP+); 85 +/- 11% (RE+ RP-); 79 +/- 15% (RE- RP-), as there is no difference for the five year disease-free survival between N- RE+ RP+ patients (84 +/- 14%) and N+ RE+ RP+ patients (84 +/- 13%).
