NCT03082846 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 16

No results posted yet for this study

Summary

Postoperative conventional radiation at 60 Gy/30f is currently still considered the standard radiotherapy mode for high-grade gliomas; however, the efficacy is still unsatisfactory. Studies in recent years have shown that hypofractionated simultaneous integrated boost-intensity modulated radiation therapy (SIB-IMRT) has certain survival benefits over other fractionation methods; but, the best hypofractionation mode and its efficacy have not been confirmed. The purpose of this study is to investigate the maximum tolerated dose (MTD) of hypofractionated SIB-IMRT with stepwise escalating of doses combined with temozolomide (TMZ) for the treatment of malignant gliomas.

Conditions

  • Glioma
  • Radiotherapy, Intensity-Modulated
  • Maximum Tolerated Dose

Interventions

RADIATION

hypofractionated radiation

The simultaneous integrated boost-intensity modulated technology is adopted to increase both the dose in the surgical cavity and residual tumor (PTV1).The dose at each fraction is gradually increased from 2.8 Gy/f (total of 20 times) with an escalating dose interval of 0.4 Gy in PTV1, until dose-limiting toxicity is present,the highest target single dose is 4 Gy/f. The planning target volume (PTV2) including the 2 cm region around surgical cavity and residual tumor remain unchanged, with 2.5 Gy each time and a total of 50 Gy/20f.

DRUG

Temozolomide chemotherapy

Temozolomide(TMZ) is administered orally every day at 75 mg/m2 during radiotherapy and at 150-200 mg/m2 for 12 cycles following completion of chemoradiotherapy.
