On the other hand, the same ER+PgR− phenotype among the three tumor types with positive steroid receptors showed slower tissue invasion than the ER+PgR+ phenotype of the same tumor type (progression rate differences by 38% for Luminal A, 46% for Luminal B1 and 67% for Luminal B2 with Ki67 > 14%). The gene discussed is PGR; the disease is neoplasm.
