METHOD OF PREDICTING EFFICIENCY OF LOCAL CHEMICAL THERAPY IN TREATMENT OF PATIENTS WITH MALIGNANT TUMOURS OF BRAIN Russian patent published in 2011 - IPC A61B10/00 G01N33/52 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to oncology and can be used for predicting efficiency of local chemical therapy of brain in patients with malignant tumours of central nervous system. For this purpose during surgical intervention for ablation of brain tumour from perifocal zone of tumour taken is brain tissue, which is divided into samples, 100 mg each. Number of samples is limited by number of studied chemical preparations. Chemical preparationbs are added to samples in dose 0.2 mg. Incubation at temperature 37°C for 30 minutes is performed. Activity of alpha-2-macroglobulin is determined before and after incubation. If index increases by 40% and more, in comparison with the value before incubation, efficiency of chemical preparations is predicted.

EFFECT: method ensures high specificity, possibility of objective evaluation of efficiency of chemical preparation impact in performing analysis on operation day, which makes it possible to start adequate therapeutic measures, including cancelling or replacement of chemical preparation in each specific case.
