Study of correlation between biochemical indicators and radiological diagnostic parameters of breast cancer.

The aim of this work was to study the correlation between some biochemical parameters and parameters of radiological diagnostics for early diagnosis of breast cancer. 76 patients with breast cancer were examined. In 48 of them was diagnosed breast cancer, in 28 of them was diagnosed benign breast neoplasms. The age of patients ranged from 18 to 79 years. The control group consisted of 16 healthy women. Oncological markers (CEA, CA 15-3), some pro-inflammatory and inflammatory cytokines (IL-2, IL-6, IL-8, IL-10 and TNF-α) and lactoferrin were determined in serum by using enzyme-linked immunosorbent assay method. All patients underwent ultrasound with a combination of Doppler and X-ray mammography. Ultrasound examination assessed the estimation of tumor size, contours, echogenicity, echostructure, the presence and nature of vascularization of breast tumors, and also assessed the location of regional lymph nodes. During mammography, the contours and sizes of the detected tumor were determined, and the presence of microcalcifications was also taken into account. The results of the study showed that a statistically positive correlation between some biochemical parameters and parameters of radiological diagnostics was established.
