Progress in radiation therapy on bone metastasis of cancer

恶性肿瘤在病程中约有50%可发生骨转移,尤其以前列腺癌、肺癌和乳腺癌多见。姑息性放射治疗通常以局部外照射的方式实现。本文从骨转移的照射剂量与剂量分割方式、复发病例的再程放疗、多发骨转移的放疗及下肢骨和骨盆承重骨转移的放疗四个方面进行了综述分析,总结治疗现状、观点分歧并探寻研究进展。

In the course of diseases, about 50% malignant tumors may occur bone metastases, particularly the pros- tate, lung and breast cancer are more common. Palliative radiation therapy comply usually by the way of local external irradiation. Now from four aspects to summarize the radiotherapy utilizing in bone metastases, including the total irradi- ation dose and dose fractionation, re - course radiotherapy in recurrent cases, how to curing multiple bone metastases, how to treat lower limb and pelvic load - bearing bone metastases.
