METHOD FOR TREATING PATIENTS WITH LOCALLY METASTASING FORMS OF CANCER AT LOCALIZATION IN MUCOSAL AREA OF PHARYNGEAL ORAL DEPARTMENT Russian patent published in 2005 - IPC

FIELD: medicine.

SUBSTANCE: the method deals with 2 courses of polychemotherapy at the first stage due to regional intra-arterial introduction of cisplatin at the dosage of 100 mg/m² during the first day of every course and 6-h-long intra-arterial infusion of 5-fluorouracil at total dose of 750 mg/m² in the morning since the 2^nd to the 6^th d of every course. Chemotherapy should be performed at the background of total magnetotherapy at frequency of magnetic field being 98-112 Hz, intensity of 25-30 oersted, duration of every seance being 30 min, the number of seances corresponds to the duration of chemotherapeutic courses. At the second stage in 2-3 wk after finishing chemotherapy it is necessary to conduct the course of distance radiation therapy (DRT) at multifractioning the dosage by SFD being 1.2 Gy twice daily 5 times weekly up to TFD being equivalent to TDF (time-dosage-fraction) of 62-70 Gy onto primary focus and 40-46 Gy onto areas of regional lymph outflow. As modifiers one should apply cisplatin during the first 2 wk of radiation therapy, hyperbaric oxygenation during the first 10 d of radiation therapy and total magnetotherapy since the 11^th d of DRT course till its ending. At the third stage in case of residual metastases in lymph nodes of patient's neck in 2-3 wk after the end of radiation therapy one should conduct operative interference in lymph outflow pathways. The method enables to decrease toxicity of chemo-and radiation therapy due to decreased radiation reactions, stimulation of immune system and improved microcirculation.

EFFECT: higher efficiency of therapy.
