目的提高对腹膜后化学感受器瘤的诊治水平。方法对松花江流域4所医院收治的21例腹膜后化学感受器瘤的临床资料进行回顾性分析。结果经BUS、CT或动脉造影等辅助检查,21例均显示为腹膜后占位性肿块,其中2例经MRI及动脉造影确诊为腹膜后化学感受器瘤; 19例误诊,误诊率为90．5％(19／21)。21例痘理诊断为腹膜后化学感受器瘤,其中8例为低度恶性。 21例均行手术治疗,16例手术完整切除肿瘤,占76．2％(16／21);5例术中未能切除。其中4例于手术后11个月内死亡,1例术中死亡。16例切除者中有11例存活12年后失访,3例低度恶性者存活 8年,有2例随访3年仍存活。结论术前诊断困难,手术切除是治疗腹膜后化学感受器瘤的惟一有效的方法。
Objective To improve the diagnosis and treatment of retroperitoneal chemoreceptors. Methods The clinical data of 21 cases of retroperitoneal chemotherapeutic neoplasms in 4 hospitals in Songhua River basin were retrospectively analyzed. Results All the 21 cases were diagnosed as retroperitoneal mass by assisted examination such as BUS, CT or arteriography. Two of them were diagnosed as retroperitoneal chemosurgery by MRI and arteriography. The misdiagnosis rate was 90.5 % (19/21). 21 cases of pox diagnosis of retroperitoneal chemoreceptors, including 8 cases of low grade malignancy. Twenty-one patients underwent surgical treatment, and 16 patients underwent complete resection of the tumor, accounting for 76.2% (16/21). Five patients failed resection. Four of them died within 11 months after operation, and one died during operation. Eleven of the 16 resected patients were lost to follow-up after 12 years of survival, 3 of the patients with low-grade malignancy survived 8 years and 2 survived 3 years of follow-up. Conclusions Preoperative diagnosis is difficult and surgical resection is the only effective method for the treatment of retroperitoneal chemoreceptors.
