RESUMEN
Objective To evaluate the curative effect and feasibility of three dimensional conformal radiation therapy for bony metastases,and summarize its indication.Methods Total of 53 patients with bony metastases were received radiotherapy.Results All patienrs were followed up from 3 to 12 month,6 patients discharged from hospital without any therapy,the ratio of change of pain and Clinical symptoms is 88.68％(47/53),the ratio of obviously improvement is 66.04％(35/53),the ratio of improvement is 22.64％(12/53).Conclusion The results show that Three dimensional conformal radiation therapy has obvious advantage and commendable effect on bony metastases.It is a high-performance,save and precise stereotaxis treatment facility.
RESUMEN
A case of Wilms' tumor in a 67 year-old female is presented. The tumor totally replaced the left kidney with extension to Gerota's fascia, the adrenal gland and ureter, with tumor thrombi in the left renal vein. Multiple bony metastases to the skull, shoulder, rib, ilium, acetabulum and femur were noted also. Microscopically, the tumor was composed predominantly of blastemal tissue with diffuse anaplasia with areas of tubular differentiation and chondroid elements. Clear cell nests were found in the proximal ureter with gradual maturation downward.
