【摘要】 目的：评估¹⁸F-FDG PET/CT在肾透明细胞癌（ccRCC）Fuhrman分级与分期中的应用价值。资料和方法 ：本研究为回顾性分析，收集2016年1月—2019年12月在我院行¹⁸F-FDG PET/CT检查且病理确诊为ccRCC的患者36例，均单发；对高低分化和有无转移ccRCC的病灶最大径（MD）和最大标准摄取值（SUVmax）进行比较；评估¹⁸F-FDG PET/CT在ccRCC分级、分期中的准确性。结果：SUVmax和MD都可作为ccRCC Fuhrman分级和区分有无转移的重要参数，SUVmax 4.1和MD 37 mm可作为判别高分化ccRCC的截点，SUVmax 4.4可作为判断转移的截点。对治疗前ccRCC的分期¹⁸F-FDG PET/CT准确率为86.1%。结论：¹⁸F-FDG PET/CT在ccRCC治疗前分级和分期中有较高价值。更多还原

【Abstract】 Objective: To evaluate the value of ¹⁸F-FDG PET/CT in Fuhrman grade and staging of clear cell renal carcinoma（ccRCC）. Materials and Methods: Thirty-six patients who underwent ¹⁸F-FDG PET/CT and were pathologically diagnosed as ccRCCC from January 2016 to December 2019 were retrospectively analyzed. The maximun diameter（MD） and maximum standardized uptake value（SUVmax） of the lesion obtained from ¹⁸F-FDG PET/CT examinations were analyzed, and SUVmax and MD between the high and low differentiated ccRCCs and between ccRCCs with and without metastasis were compared. Then the accuracy of the ¹⁸F-FDG PET/CT in the ccRCC grade and staging was evaluated. Results: Both SUVmax and MD could be used as important parameters for Fuhrman grade and distinguishing whether there was metastasis. SUVmax4.1 and MD 37 mm could be used as cut-off for distinguishing highly differentiated ccRCC. SUVmax 4.4 could be used as a cut-off for tumor with metastasis. The accuracy of ¹⁸F-FDG PET/CT for tumor staging before treatment of ccRCCs was 86.1%.Conclusion:¹⁸F-FDG PET/CT is of high value in Fuhrman grade and tumor staging before treatment of ccRCC.更多还原
