摘要 目的探讨正电子发射计算机断层显像/X线计算机体层成像(PET/CT)检测在结外自然杀伤细胞/T细胞淋巴瘤(NK/TCL)临床预后判断中的应用价值。 方法选取首都医科大学附属北京同仁医院病理科2007年1月至2016年7月间确诊、并于初诊时进行PET/CT检查的72例NK/TCL住院病例,回顾性分析PET/CT检测结果。采用Kaplan-Meier方法分析PET/CT发现的阳性指标与总生存期的关系。 结果男54例,女18例,中位年龄44.5岁,中位随访时间29.2个月。发病部位:单侧鼻腔26例(36.1%),双侧鼻腔36例(50.0%),鼻咽、口咽及喉咽10例(13.9%)。51例(70.8%)累及周围组织:累及鼻翼29例(40.3%)、鼻窦29例(40.3%)、颌面部软组织18例(25.0%)、眼眶12例(16.7%)、上下颌骨及颅底骨8例(11.1%)、眼睑6例(8.3%)、脑组织3例(4.2%)、眼球2例(2.8%)。颈部及腹股沟淋巴结肿大54例(75.0%)、脾大10例(13.9%)、肝大2例(2.8%)。Kaplan-Meier单因素生存分析发现临床分期和国际预后指数(IPI)均分别与预后相关(均P〈0.05),颌面部软组织、眼睑、眼眶、颌骨及颅底骨及脑组织受累的患者的总生存时间与未受累者相比,差异均有统计学意义(均P〈0.05),扁桃体及腭部、鼻翼鼻根及鼻前庭、鼻窦受累者与未受累者,总生存差异均无统计学意义(均P〉0.05)。Cox回归模型多因素分析显示颌骨及颅底受累为独立不良预后因素(P〈0.05)。 结论PET/CT检查能通过显示肿物结构及代谢状况两方面的因素,准确地检测出结外NK/TCL的肿瘤侵犯相邻及远隔组织的范围,对临床分期及预后判断具有重要价值。 ObjectiveTo explore the value of Positron-Emission Tomography/Computed Tomography(PET/CT)in the prognosis of extranodal NK/T cell lymphoma. MethodsThe patients of NK/T cell lymphoma diagnosed from January 2007 to July 2016 in Department of Pathology of Beijing Tongren Hospital were enrolled in this study.Seventy-two in-hospital patients were examined on the invasion of adjecent tissue or organ by PET/CT.The PET/CT results were analyzed retrospectively.Kaplan-Meier method was used to analyze the prognostic value of the positive results by PET/CT on overall survival(OS). ResultsThere were 54 males and 18 females with median age of 44.5 years(13-75 years).According to Ann Arbor staging system,there were 16 cases(22.2%)in stage Ⅰ,29 cases(40.3%)in stage Ⅱ,6 cases(8.3%)in stage Ⅲ and 21 cases(29.2%)in stage Ⅳ.According to the IPI scoring system,there were 34 cases(47.2%)in the low risk group(0-1 point),21 cases(29.2%)in the low-middle risk group(2 points),16 cases(22.2%)in the middle-high risk group(3 points),and 1 case(1.4%)in the high risk group(4-5 points).The median follow-up time was 29.2 months(1-118 months).The disease occured in unilateral nasal cavity in 26 cases(36.1%),bilateral nasal cavities in 36 cases(50.0%),nasopharynx,oropharynx and pharynx in 10 cases(13.9%).The tumors of 51 cases involved the surrounding tissue,including nasal wings in 29 cases(40.3%),nasal sinus in 29 cases(40.3%),maxillofacial soft tissue in 18 cases(25.0%),orbital in 12 cases(16.7%),maxilla and skull base in 8 cases(11.1%),eyelid in 6 cases(8.3%),brain tissue in 3 cases(4.2%),eyeball in 2 cases(2.8%).In addition,cervical and inguinal lymphadenopathy were found in 54 cases(75.0%).Splenomegaly and hepatomegaly were found in 10 cases(13.9%)and 2 cases(2.8%),respectively.Survival analysis showed that the clinical stage and IPI were significantly associated the clinical prognosis(P=0.000,0.001,respectively).Involvement of the maxillofacial soft tissue,eyelid,orbital,maxilla and skull base and brain tissue were significantly related to reduced the overall survival time(P=0.006,0.000,0.024,0.001 and 0.015,respectively).Involvement of palate or tonsil,the nosewingand nasal sinus did not show significant shorter overall survival(P=0.091,0.063,and 0.139,respectively).Cox regression multivariate analysis showed maxilla and skull base involvement was independent adverse prognostic factor(P=0.047). ConclusionsThe PET/CT examination can accurately detect the extent of adjacent and distant tissues of tumor involvement of NK/T cell lymphoma by showing the tumor structure and metabolic status,thus has important value in the clinical staging and prognosis predication.
