Summary. Study of tumor aggressiveness by laser DNA flow cytometry enables prediction of cytostatic therapy effectiveness and timely conduct of its correction. The Department of Radiation Oncology, National Cancer Institute developed methods chemoradiotherapy (CRT) patients with locally advanced cancers of the cervix (cervical cancer MR). Before treatment patients underwent complex examination, including DNA index determination by laser DNA flow cytometry based on biopsies of the cervix. During concomitant radiotherapy were used cytotoxic drugs in radiomodifying doses. Conducted to investigate the possibility of monitoring the effectiveness of treatment at the subcellular level. The treatment and analysis of the clinical and instrumental monitoring data in 87 patients with MR of cervical cancer (69 patients studied and 18 — control group). Analysis of the direct method results CRT showed that the dynamics of DNA clones of tumor status correlates with clinical data obtained in response to cytotoxic therapy MR cervical cancer. Positive response of tumors in patients with cervical cancer MR after a full course chemoradiation increased by 25.0% in comparison with standard methods. Toxic effects of treatment on the number and severity of patients in the study group did not differ from the control group, did not exceed the second degree.
