7.P.30 MODIFIED PROLONGED INTRAARTERIAL CHEMOTHERAPY IN COMPLEX TREATMENT PATIENTS WITH OSTEOGENE SARCOMA OF LOWER EXTREMITIES

Abstract

In 36 patients was carried out short-lived hyperglycemia and local hyperthermic prolonged intraarterial chemotherapy on the background of modificators of short-lived hyperglycemia in the department of general oncology of R. O.S. C of the H.M of the Republic of Uzbekistan. Tumour has localized in distal part of femoral bones in 18 patients, in proximal part of cannon bones in 13. Treatment was carried out by the scheme of Syclophosphan 1000 mg/m2 doxorubicin 90 mg/ m2 48-hourly unbroken infusion, cycplatin 100 mg2 in the dependence from efficacy of the treatment has been carried out from 1 to 4 courses In 3–4 hours time after beginning prolonged intraarterial chemotherapy unbrokenly began short-lived hyperglycemia by the way of introduction i/v solution of glucose 20% to1500ml. Maximal concentration of the blood sugar level has composed 18–23ml in the period of treatment. Then local hyperthermia with USD apparatus was carried out in 30MG frequency regime with exposition of 20 min. time. Control group of the patients has composed patients, who has performed system chemotherapy by analogical scheme CAP (in 34 patients). In the patients group, who received prolonged intraarterial chemotherapy with modificators (short-lived hyperglycemia with local hyperthermia) in 4 (11, 1%) patients have been observed full effect, in 25 patients (69, 4%) partial effect, in 5 (13,9%) stabilization, and in 2 (5,6%) progressing of tumour process. Safe operation was performed in 17 patients (47, 2%), crippling in 4 (11,4%) patients, conservative treatment in 15 patients (41,6%) in this group. In patients, who was carried out system chemotherapy full effect was marked in 2 (5,9%) patients, partial effect in 8 (23,5%), stabilization in 15 (44,1%) and progressing in 9 (26,5%) patients. Safe operations were carried out in 3 (8,8%), crippling operations in 19 (55,9%), other 12 (35,3%) patients are under observation after conducting 9 courses of chemotherapy and beam therapy without operation in conservative treatment.

Endovascular chemotherapy in combination with local hyperthermia and short – lived hyperglycemia allows overcoming medicinal steadiness and increases quantity of safe operations. That’s why combination prolonged intraarterial chemotherapy with modifications is aimed.
