The aim of the work is to conduct a comparative analysis of the values of initial hematological and biochemical parameters of patients with breast cancer of stages IIB–IIB with and without late radiation complications (LRC). Materials and methods. There was performed a retrospective analysis of 81 medical histories of female patients with breast cancer (45 patients with LRC and 36 patients without LRC after radiation therapy) who received in-patient treatment at Grigoriev Institute for Medical Radiology and Oncology of the NAMN of Ukraine for the period 1994–2018, including radiation therapy. Two groups of patients with stage IIIB–IIIB breast cancer were formed: I (23 patients with LRC) and II (22 patients without LRC). Results. Characterizing the hematologic indices of patients with IIB–IIIB stages breast cancer, it should be noted that patients with LRC after radiation therapy were found to have decreased (p = 0.1) red blood cell count by 6.7 % (3.80 ± 0.11 × 1012/l) and decreased hemoglobin level (p = 0.09) by 6.1 % (of 114.50 ± 2.53 g/l) compared to baseline values. The analysis of biochemical indicators showed that patients with stage IIIB–IIIB breast cancer with LRC had higher values of total protein (by 9.9 %, p = 0.04), bilirubin (by 6.2 %, p = 0.5), glucose (by 9.1, p = 0.09) and aminotransferases (ALT by 8.6 %, p = 0.4, ASAT by 31.9, р = 0.005) compared to the values of patients in the control group. When evaluating the indicators of the blood clotting system, it should be noted that patients with stage IIIB–IIIB breast cancer with LRC had a higher clotting time (p = 0.4) by 17.9 % and a statistically significantly (p = 0.03) higher level of fibrinogen by 23.3 %. Conclusions. It was found that 78.30 ± 0.09 % of patients with IIIB–IIIB breast cancer with LRC were diagnosed with inflammatory changes, 47.8 ± 0.10 % of patients — with fibrotic, 13.00 ± 0.07 % of patients — with hematological and 4.30 ± 0.04 % — with degenerative changes. It was found that in the structure of concomitant diseases in patients with stage III–III breast cancer, cardiovascular diseases (78.0–84.4%), diseases of the digestive system (33.3–44.4 %) and nervous system (36.1–42.2 %) are most often diagnosed. It was shown that the initial level of hematocrit was higher among the hematological indicators in patients with stage IIIB–IIIB breast cancer with LRC (37.0 [34.8; 38.4] %) (p = 0.09) by 9.7 %, the content of white blood cells (5.8 [4.8; 6.5] × 109/l) was higher (p = 0.1) by 6.1 %, and ESR (16 [6; 18] mm/h) was higher (p = 0.1) by 60.0 % compared to the baseline parameters of patients without LRC. The analysis of biochemical indicators showed that patients with stage IIIB–IIIB breast cancer with LRC had higher values of total protein (by 9.9 %, p = 0.04), bilirubin (by 6.2 %, p = 0.5), glucose (by 9.1, p = 0.09) and aminotransferases (ALT by 8.6 %, p = 0.4, ASAT by 31.9, р = 0.005) compared to the values of patients without LRC.References
