摘要
目的 探讨肝移植术后新发恶性肿瘤的临床特征、危险因素和防治措施.方法 回顾性分析2003年8月至2008年12月间行肝移植术的726例受者中新发恶性肿瘤的临床资料.结果 在726例肝移植受者中,术后新发恶性肿瘤4例,发生率为0.6%;患者均为男性;新发恶性肿瘤的类型分别为：急性髓性白血病、胃癌、肺癌和未分化肝肉瘤;患者肝移植时年龄为42～57岁,中位年龄52岁,肿瘤确诊时的年龄为45～60岁,中位年龄53岁;从接受肝移植手术至发生肿瘤的时间为6～38个月,中位时间31个月.4例患者均死于肿瘤进展和多器官功能衰竭.肝移植术至死亡时间为12～48个月,中位时间39.5个月;确诊为新发恶性肿瘤至死亡时间为6～10个月,中位时间8.5个月.结论 肝移植术后新发恶性肿瘤国内发病率低于国外;确诊时间较晚是患者死亡的主要原因;重视癌前病变和高危因素,早期诊断,早期治疗是提高疗效的关键.
Objective To analyze the clinical characteristics, risk factors, prevention, and treatments of de novo malignant tumors after orthotopic liver transplantation （OLT）. Methods The clinical data of 4 patients with de novo malignant tumors out of the 726 patients undergoing OLT from October 2003 to December 2008 were analyzed. Results The morbidity of de novo malignant tumors after OLT was 0.6 % （4/726）, and all of them were men. The 4 de novo malignant tumors were respectively diagnosed as acute myeloid leukaemia, gastric carcinoma, lung cancer, undifferentiated embryonal sarcoma of the liver. The age of patients during OLT was 42-57 years （mean 52 years）. The age of patients＇ onset was 45-60 years （mean 53 years）. The length was 6-38 months from liver transplantation to diagnosis of de novo malignant tumors （mean 31 months）. All of the 4 patients died of tumor progression and multiple organ failure. The survival time was 12-48 months after OLT （mean 39.5 months）, and that was 6-10 months after diagnosis of de novo malignant tumors （mean 8.5 months）. Conclusion The incidence of de novo malignant tumors after OLT in China is lower than in abroad. The delayed diagnosis time is a main cause of death for patients with de novo malignant tumors after OLT. To think highly of precancerous lesions and high risk of factors, early diagnosis, and early treatment are the keys to improve the survival time.
