Health condition(s) or Problem(s) studied:

Highly malignant astrocytic tumors.

Intervention(s):

Group I. Radiant+hR3 MAb treatment Forty patients to be included: - Conventional radiant treatment (60Gy). This treatment will be conducted during 6 weeks until hR3 MAb and radiotherapy in highly malignant astrocytic tumors, until reaching the final dose. 1st week 8Gy (+-2Gy), 2nd week 18Gy (+-2Gy), 3rd week 28Gy (+-2Gy), 4th week 38Gy (+-2Gy), 5th week 48Gy (+-2Gy), and 6th week 58Gy (+-2Gy). - h-R3 MAb. One 200mg MAb dose will be administered by intravenous route (antecubital vein) in 25ml saline solution (0.9% NaCl), once a week, for 6 weeks. Once the radiant therapy is completed, patients will receive one 200mg hR3 MAb maintenance dose every 21 days until reaching one year treatment. Group II. Radiant+Placebo treatment Forty patients to be included: - Conventional radiant treatment (60Gy). The same way as in Group I. - Placebo. Four placebo bulbs will be administered by intravenous route (antecubital vein) in 250ml saline solution (0.9% NaCl), once a week, for 6 weeks. Once the radiant therapy is completed, patients will receive 4 placebo bulbs every 21 days until reaching one year treatment.
