合并上腔静脉综合征的原发心脏恶性肿瘤的放射治疗

Radiation therapy to malignant tumor of heart with superior vena cava syndrome

目的:探讨对合并上腔静脉综合征的原发心脏恶性肿瘤的放射治疗作用。方法:分析、总结3例合并上腔静脉综合征的原发心脏恶性肿瘤病人的治疗过程,复习相关文献。2例行术后放疗,1例行术前放疗。放射野包括病变区在内的大部分心脏,6MVX线照射,放疗剂量分别为40GY、50.4GY、40GY,结果:3例病人经治疗后心脏肿瘤均缩小,上腔静脉综合征均明显好转。1例病人存活23个月,1例存活6个月,1例已存活9个月,目前仍无瘤生存。3例病人的生活质量均有明显改善。结论:放射治疗能有效治疗心脏原发恶性肿瘤,缓解上腔静脉综合征,改善生活质量,延长生存期。

Objective To explore the role of radiation therapy to malignant tumor of heart with superior vena eava syndrome （SVCS）. Methods The treatment procedure of 3 patients of primary malignant tumor of heart with SVCS was analysed and sumed up. 6 MV X-ray was used. The field of radiation included tumor area and greater part of heart. One patient received preoperative radiotherapy, two patients received postoperative radiotherapy. The dosage of radiation was 40 GY, 50.4 GY and 40 GY respectively. Results The malignant tumors of heart were decreased and SVCS was obviously relieved and the quantity of life was improved in 3 patients, One ease lived 23 months . One ease lived 6 months. One ease has been living 9 months without tumor. Conclusion Radiation therapy can effectively treat primary malignant tumor of heart and relieve SVCS and improved the quality of livelihood and prolong life.
