METHOD FOR COMBINED THERAPY OF LOCALLY METASTASING MALIGNANT TUMORS OF TRACHEA AND/OR BRONCHI Russian patent published in 2006 - IPC A61N5/67 

FIELD: medicine, oncology.

SUBSTANCE: one should carry out argon-plasmatic luminal recanalization of trachea and/or bronchi, at power being about 60-90 W followed by conducting brachytherapy at the length of sensor's movement trajectory of about 5-20 cm, at pace of 5 mm and depth of reference isodosage being 10 mm against the sensor. It is necessary to provide applicator's movement being 1-3 cm above and below the tumor at applying the dosage ranged 14-28 Gy once daily per 7 Gy. Then one should fulfill distance radiation therapy 5 times weekly per 1-2 Gy up to TFD being 45-55 Gy. Additionally, before the onset of radiation therapy one should carry out photodynamic therapy with "Photoditasin" preparation at 0.8-1.5 mg/kg and radiation of semiconductor laser at wave length being 662 nm and total dosage of energy being 400 J. The innovation enables to achieve the decrease of tumoral mass, reconstruct the passability of respiratory tract and decrease intoxication and pain syndrome.

EFFECT: higher efficiency of therapy.
