Radiotherapy of primary cardiac neoplasm

目的 评价放射治疗心脏恶性肿瘤的疗效。方法 1例原发性左心室恶性粘液性神经鞘瘤患者 ,姑息切除术后 ,以原发肿瘤部位为中心 ,采用AP PA(前后平行相对 )照射野行快中子放射治疗 ,2个野 /次 ,5 0ncGy/野 ,10 0ncGy/d ,共 11次完成 ,总DT10 0 4.95ncGy ,48d完成。结果 患者心脏功能恢复正常 ,随访 5年未见肿瘤局部复发和远地转移。结论 快中子治疗心脏原发恶性肿瘤疗效肯定。

Objective To evaluate the result of radiotherapy for primary cardiac neoplasm.Methods A patients with primary malignant mucinous Schwannoma in th left ventriclular wall had been treated by conservative surgery. He,then,received fast neutron radiotherapy one year after wards. Radiotherapy was given through opposing anterior and posterior fields of 7.8 cm×7.8 cm. The total radiation dose was 1?004.95 ncGy with 11 fractions of 100 ncGy in 48 days.Results The function of the patient's heart recovered after treatment. The patients has been followed for 5 years without evidence of recurrence or distance metastased. Conclusion Fast neutron radiotherapy is effective in the treatment of primary cardiac neoplasms by surgery combined with postoperative radiotherapy. It could improve the prognosis of patients with primary cardiac neoplasms.
