[Postoperative chemoradiotherapy for cerebral glioblastoma]

We developed a new method of accelerated chemoimmunoradiotherapy for cerebral glioblastoma and evaluated the immediate effects. A single focal dose of 3Gy was administered once a day 5 times a week until the total focal dose of 51 Gy was reached. Chemoradiotherapy was followed by a course of biotherapy with recombinant interleukine-2 (roncoleukine). On administering a total dose of 10 million units, a course of chemoimmunotherapeutic support was given after a 2-week break. Vincristine 1 mg was injected on day 1 and nitrosourea preparations (lomustine 160 mg or carmustine 100 mg) on day 2. Later on, the same regimen of roncoleukine was used. Our method was followed by longer survival as compared with standard treatment (control) and use of incomplete course chemoimmunotherapy.
