Aim of this study was the assessment of neuropsychological changes after whole brain irradiation. ⋯ Neuropsychological capacity in patients with SCLC was impaired even before PCI. Possible reason is the preceding chemotherapy. Whole brain irradiation did not induce a significant decline of cognitive functions in patients with PCI or TCI. A decline in a longer follow-up nevertheless seems possible.

Review Comparative Study
Radiation therapy in the multimodal treatment approach of pituitary adenoma.
Pituitary tumors are relatively uncommon, comprising 10-12% of all intracranial tumors. The treatment consisting of surgery, radiotherapy and drug therapy or a combination of these modalities is aimed at the control of tumor cell proliferation and--in endocrine active tumors--the reduction of hormone secretion. However, the slow proliferation characteristics of pituitary tumors necessitate long-term studies for the evaluation of the treatment results. In the last decade there has been continuous improvement in surgical procedures, radiotherapy techniques and drug generation. In this paper, literature will be reviewed to assess the role of modern radiotherapy and radiosurgery in the management of pituitary adenomas. ⋯ Conventional radiation therapy of pituitary adenoma is highly effective. It is recommended after subtotal resection of primary tumors such as macroadenomas, after gross total resection from endocrine active adenomas with postsurgical hormone secretion and for recurrent tumors. Radiosurgery seems to be a possible treatment alternative in experienced centers, and only in patients with adenomas smaller than 25-30 mm with a minimum distance of 2-3 mm to the chiasm.

To investigate the role of radiation therapy (RT) in the management of desmoid tumors. ⋯ Radiation therapy is an effective treatment after incomplete resection of desmoid tumors. We did not observe a benefit for tumor doses exceeding 50 Gy. In some patients with circumscribed intraabdominal desmoid tumors, radiation therapy might be a treatment option with low toxicity, if 3-D treatment planning is utilized.

Comparative Study
[Metastatic epidural spinal compression: prognostic factors and results of radiotherapy].
The metastatic epidural spinal cord compression is an oncologic emergency. Presently, there is no agreement on a standard diagnostic or therapeutic algorithm. In spite of improvement in diagnostic imaging, a great proportion of patients are plegic at the time of the first presentation. ⋯ Patients with a known malignant tumor and progressive or axial back pain should undergo MRI scan to rule out spinal cord compression. For patients without severe neurologic deficit and MRI proven epidural compression, radiation therapy is able to preserve walking ability and reduce pain. For patients with neurologic symptoms radiation therapy should start within 24 hours.
