This prospective clinical study used 99mTc-sestamibi (MIBI) brain SPECT to assess residual tumor volume and determine whether it would be prognostic of survival at the end of cranial irradiation in patients with malignant glioma. Methods: Fifty-seven patients with supratentorial malignant glioma were included in this clinical trial. Tomoscintigraphy was performed 4 h after an intravenous injection of MIBI (1,110 MBq). The images were obtained from a dual-head
-camera using fanbeam collimators. Transverse, coronal, and sagittal views were reconstructed. Metabolic tumor volume (MTV), using an ellipsoid model, was calculated from the 3 slices. The first posttherapeutic neuroradiologic evaluation was performed at the end of each patients radiation therapy. Results: 99mTc-MIBI brain SPECT performed at the end of cranial irradiation provided data that allowed the identification of residual tumor and could be used to accurately predict survival of malignant glioma patients, taking into account the established prognostic factors. Patients with an MTV < 32 cm3 had a median survival of 358 d, as opposed to 238 d in patients with an MTV
32 cm3 (P = 0.05). Moreover, half of CT scans performed at the same time were considered to show doubtful or only suggestive findings. No diagnosis of tumor progression or inflammatory changes was possible. Conclusion: 99mTc-MIBI brain SPECT may help in establishing the prognosis of glioma patients at the end of radiation therapy. Consequently, the management of patients can be adapted. These new data should be considered in the design of future clinical studies of malignant glioma patients as a way to quickly assess the efficiency of therapies.
