METHOD FOR INTEGRATED TREATMENT OF EARLY ANAL SQUAMOUS CELL CARCINOMA

摘要

FIELD: medicine.;SUBSTANCE: method involves teletherapy combined with a local electromagnetic hyperthermia, chemotherapy with cisplatin and bleomycin, metronidazole as an ingredient of a composite mixture introduced through rectum. Teletherapy is conducted with using a continuous course of 3D and IMRT planning with photons 6-18 MeV covering the tumour and regional metastases in a single basic dose of 1.6 to 1.8 Gy daily 5 times a week, 27-30 fractions, in a total radiation dose of 48.0-48.6 Gy. At the same time, the tumour is exposed to teletherapy with using a simultaneous integrated boost in a single basic dose of 2.0 to 2.2 Gy, 27-30 fractions, in a total radiation dose of 59.4-60.0 Gy.;EFFECT: method enables reducing a radiation exposure, a teletherapeutic dose on the surrounding critical structure, saving the time and conducting a fewer sessions of teletherapy, ensuring lower intensity and the number of toxic reactions, the total length of treatment, eliminating early recurrences.;2 ex
