Accurate prognosis of patients with luminal type A and HER‑2 overexpressing breast cancer via the partitioning calculation method of the Ki‑67 index

The aim of the present study was to perform accurate prognosis different molecular types breast cancer (BC) by using partitioning calculation method Ki‑67 index. Partitioning used judge index and type classified according 2019 Chinese Society Clinical Oncology guidelines in 199 cases BC. association between overall survival (OS), disease‑free (DFS) analyzed Chi‑squared test. Survival analysis performed Kaplan‑Meier with statistical SPSS 18.0 software. results revealed that 5‑year rate patients BC 18.60% (8/43), 6‑year 38.24% (26/68), while 10‑year 73.08% (133/182); indicated almost 80% succumbed during 5 years following diagnosis. Marked differences were found OS (between 50 54%) (χ2=4.83, P=0.028; χ2=4.60, P=0.032 respectively). All 14 luminal A subtype a ≤4% survived at end follow‑up time (69‑156 months). At same time, there marked difference two groups overexpression HER‑2 50% as cut‑off point (χ2=5.54, P=0.019). On whole, demonstrates can be accurately. subtypes may associated
