An international workshop designed a response criteria in order to standardize care and help clinical decision making (Table 29. Secondary to con- cerns of radiation-induced toxicity, the role of radiation has been decreasing, and current trends include response-based treatment, dose de-escalation, and withholding of radiation. Multiple chemotherapy agents show promise including temozolomide, rituximab, topotecan, and high-dose chemotherapy with stem cell rescue (Table 29. Chemosensitive rescue)e patients then received intensive chemotherapy of thiotepa at 250 mg/m2/day plus busulfan at 10 mg/kg and cyclophos- phamide.

For incomplete responders to induction che- motherapy, a smaller boost volume to the gross residual tumor may be used. A head immobilization device with thermoplastic mask should be used, and radio-opaque markers should be placed at the ocular canthi. For a patient with an incomplete response to induction chemotherapy, a boost is needed to gross disease. In a patient with ocular involvement after induction chemotherapy, both eyes should be included in the field for a total dose of 36 Gy in 2 to 1. In a patient receiving radiation without chemo- therapy, 45 Gy should be given to the entire brain. Care should be taken to properly cover the anterior temporal bone and cribriform plate. The anterior field edges of the lateral beams should be coplanar to minimize divergence into the eyes. Lo Key Points ? Meningiomas are the most common benign intracranial tumor in adults and tend to be slow growing, and usually have favorable long-term prognoses. Meningiomas make up 20–30% of all intracranial tumors and are the most common intracranial tumor in adults. While most meningiomas arise sporadically, several risk factors have been implicated in the etiology of meningiomas (Table 30. Ninety percent of meningiomas occur intracranially, and the remaining 10% occur in the spine. The most common intracranial loca- tions include the following: cerebral convexity, falx cerebri/parasagittal si- nus, sphenoid wing, base of skull, and posterior fossa. Chapter 30 Meningioma 875 Pathology Meningiomas arise from arachnoid cap cells, which are the epithelial cells of the arachnoid villi. Microscopically, they have a bland, whorled appearance, with or without psammoma bodies. There are several histological variants including fibrous, transitional, clear cell, chordoid, rhabdoid, and angiomatous. Lo Routes of Spread Meningiomas spread via local extension, regional lymph nodes, and cerebro- spinal fluid.

Narrative reasoning is necessary one cannot make a good decision about when to interpret the actions of others and to respond to give a client a splint, or figure out how to appropriately to the social context. Bruner (1986, get that client to wear it, without developing a 1996) referred to it as a capacity to ‘read other capacity to assess the beliefs, values, and concerns minds,’ that is, to make accurate inferences about of the client.
