ReviewProlonged oral hydroxyurea and concurrent 3d-conformal radiation in patients with progressive or recurrent meningioma: results of a pilot study.
Treatment of recurrent and progressive meningiomas remains a challenge in clinical neurooncology. This study was designed to evaluate the efficacy of the simultaneous application of 3d-conformal radiotherapy and chemotherapy with hydroxyurea (HU). ⋯ Results obtained in this study indicate that treatment with HU and simultaneous radiotherapy is safe and effective with disease stabilization in the majority of patients. Randomized trials comparing radiosurgery versus radiochemotherapy versus fractionated radiotherapy are warranted.

Case ReportsHuge bilateral pulmonary and pleural metastasis from intracranial meningioma: a case report and review of the literature.
A case of recurrent meningioma with atypical features and extracranial metastases is reported. A 34-year-old female was operated in 1996, 2000, and 2002, and frontal parasagittal meningioma was extirpated. Histological diagnoses of all the resected tumors were meningotheliomatous meningioma, WHO Grade I. ⋯ Cytopathology was consistent with malignant meningioma, metastasis from the patient's known intracranial meningioma. Ki-67 staining index at the primary and metastatic sites of the present cases were 7 and 5%, respectively. We reviewed and discussed the histopathological features and mechanisms of metastasizing meningioma.
