DIFFERENTIAL DIAGNOSTIC TECHNIQUE FOR BENIGN PROSTATE HYPERPLASIA AND PROSTATE CANCER Russian patent published in 2012 - IPC G01N33/53 G01N33/574

Abstract RU 2464569 C1

FIELD: medicine.

SUBSTANCE: ultrasonic data are used to measure prostate volume. Thereafter patient's blood is examined for levels of total and free prostate-specific antigen (PSA). Additionally, the age is patient reported. It is followed by calculating a diagnostic coefficient (C_d) by formula: C_d=6.14-0,18(A)-3.19(L_tpsa)+7.66(L_tpsa)+140[(L_tpsa):(L_p)]+0.09(L_p) wherein A is the patient's age, completed years; (L_tpsa) is the level of total PSA, ng/ml; (L_spsa) is the level of free PSA, ng/ml; (L_p) is prostate volume, cm³. If C_d>0, benign prostate hyperplasia is diagnosed. The value C_d<0 enables diagnosing prostate cancer.

EFFECT: technique enables high-reliability differential diagnosis of benign prostate hyperplasia and prostate cancer.
