Microscopic examination revealed it to be a schwannoma. The residual tumor was treated with fractionated three-dimensional conforma...
Haemangiopericytoma is a rare, highly vascular, slow-growing tumour which has both malignant and benign varieties. We report a case of a 63-year-old man in whom it was treated by initial radiotherapy followed by complete surgical excision. The preoperative radiotherapy markedly reduced the vascularity of the tumour. A brief review of the pathology and nature of tumour is provided. q 1999 Elsevi...

However there has been a general exclusion of the elderly patients from neoadjuvant trials often due to concerns over their tolerance of surgery and/or (chemo)radiotherapy.

Over a 16-year period, 105 patients with pituitary adenoma accompanied by visual disturbance underwent transcranial intracapsular removal of the tumor followed by radiotherapy. Postoperative recovery of visual function in these patients was compared with the results obtained in other institutions after trans-sphenoidal surgery. The severity of preoperative visual impairment was correlated with ...
Short course hypo-fractionated radiotherapy is a standard regime for the palliation of stage IV head and neck cancers. However few patients respond favorably and require further radiotherapy in curative intent. We have used split-course radiotherapy technique to find out this conversion rate from palliative to curative intent. This was a prospective study conducted from November 1998 to October...
Carcinosarcoma of the uterus is a rare tumor representing 2-4% of uterine malignancies. Its prognosis is poor with a 5 years survival rate of 10-30%. We report a first documented case of carcinosarcoma occurring in a 62 years old woman who presented with postmenopausal vaginal bleeding for one year. The preoperative biopsy of endometrium revealed a leiomyosarcoma. Total body Computerized Tomogr...
BACKGROUND Glioblastoma is associated with a poor prognosis in the elderly. Survival has been shown to increase among patients 70 years of age or younger when temozolomide chemotherapy is added to standard radiotherapy (60 Gy over a period of 6 weeks). In elderly patients, more convenient shorter courses of radiotherapy are commonly used, but the benefit of adding temozolomide to a shorter cour...
