目的 探讨18F-脱氧葡萄糖正电子发射计算机断层显像(FDG-PET)对淋巴瘤患者分期及预后评估的作用.方法 对初诊的41例淋巴瘤患者,化疗前和化疗4个疗程后行FDG-PET,中位随访30个月,比较化疗前FDG-PET分期和化疗4个疗程后FDG-PET结果对预后的影响.结果 41例患者治疗前结内、外病灶的最大标准摄取值(SUVmax)分别为9.7±6.9和8.4±6.8.侵袭性非霍奇金淋巴瘤(NHL)和惰性NHL比较,结内、外病灶的SUVmax值差异有统计学意义(侵袭性NHL分别为10.3±7.5和9.1±6.5,惰性NHL分别为4.7±2.1和2.4±0.6,均P<0.05).NHL和霍奇金淋巴瘤(HL)、B细胞和T细胞NHL、活化B与生发中心来源弥漫大B细胞淋巴瘤治疗前FDG-PET的SUVmax差异无统计学意义(P>0.05).化疗前22例(54%)患者FDG-PET检出结外器官病变;6例(15%)因FDG-PET发现CT等其他检查未显示的淋巴结或结外病变而提高临床分期.治疗前经FDG-PET分期为Ⅰ、Ⅱ期的患者15例(37%),Ⅲ、Ⅳ期的患者26例(63%).随访期间,FDG-PET分期Ⅰ、Ⅱ期的患者中1例(7%)因疾病进展死亡,Ⅲ、Ⅳ期的患者中6例(23%)因疾病进展死亡.41例患者化疗4个疗程后行FDG-PET检查,FDG-PET阴性的患者17例(41%)中,随访期间1例(6%)因疾病复发死亡,FDG-PET阳性的患者24例(59%)中,随访期间6例(25%)因疾病进展死亡.结论 化疗前FDG-PET检查有助于对淋巴瘤患者进行准确的临床分期,化疗4个疗程后FDG-PET检查有助于评估淋巴瘤患者的预后,指导进一步治疗.
目的 探討18F-脫氧葡萄糖正電子髮射計算機斷層顯像(FDG-PET)對淋巴瘤患者分期及預後評估的作用.方法 對初診的41例淋巴瘤患者,化療前和化療4箇療程後行FDG-PET,中位隨訪30箇月,比較化療前FDG-PET分期和化療4箇療程後FDG-PET結果對預後的影響.結果 41例患者治療前結內、外病竈的最大標準攝取值(SUVmax)分彆為9.7±6.9和8.4±6.8.侵襲性非霍奇金淋巴瘤(NHL)和惰性NHL比較,結內、外病竈的SUVmax值差異有統計學意義(侵襲性NHL分彆為10.3±7.5和9.1±6.5,惰性NHL分彆為4.7±2.1和2.4±0.6,均P<0.05).NHL和霍奇金淋巴瘤(HL)、B細胞和T細胞NHL、活化B與生髮中心來源瀰漫大B細胞淋巴瘤治療前FDG-PET的SUVmax差異無統計學意義(P>0.05).化療前22例(54%)患者FDG-PET檢齣結外器官病變;6例(15%)因FDG-PET髮現CT等其他檢查未顯示的淋巴結或結外病變而提高臨床分期.治療前經FDG-PET分期為Ⅰ、Ⅱ期的患者15例(37%),Ⅲ、Ⅳ期的患者26例(63%).隨訪期間,FDG-PET分期Ⅰ、Ⅱ期的患者中1例(7%)因疾病進展死亡,Ⅲ、Ⅳ期的患者中6例(23%)因疾病進展死亡.41例患者化療4箇療程後行FDG-PET檢查,FDG-PET陰性的患者17例(41%)中,隨訪期間1例(6%)因疾病複髮死亡,FDG-PET暘性的患者24例(59%)中,隨訪期間6例(25%)因疾病進展死亡.結論 化療前FDG-PET檢查有助于對淋巴瘤患者進行準確的臨床分期,化療4箇療程後FDG-PET檢查有助于評估淋巴瘤患者的預後,指導進一步治療.

Objective To evaluate the application of 18fluoro-deoxyglucose positron emission tomography (FDG-PET) to the staging and predicting outcome in patients with lymphoma.Methods 41 patients with newly diagnosed lymphoma (median age 57 years) were explored with FDG-PET prior to and after 4 cycles of chemotherapy.With a median follow-up of 30 months (range 10-68 months),the value of FDG-PET to staging and predicting clinical outcome was assessed. Results The maximum standardized uptake value (SUVmax) of nodal and extranodal lesions was 9.7±6.9 and 8.4±6.8 respectively prior to treatment.There were significant difference (P<0.05) in aggressive non-Hodgkin's lymphoma and indolent non-Hodgkin's lymphoma,no significant difference (P>0.05) in non-Hodgkin's lymphoma and Hodgkin's lymphoma (HL), B-cell neoplasms and T-cell neoplasms,germinal center B-cell-like DLBCL and activated B-cell-like DLBCL. In 41 patients, 22 patients (54 %)were detected extranodal focus by FDG-PET before chemotherapy. FDG-PET imaging upstaged in 6(15%)of initial lymphoma patients.There were 15 patients (37 %) in stage Ⅰ and Ⅱ and 26 patients(63 %)in stage Ⅲ and Ⅳ by FDC-PET scan.1 patient (7 %) in stage Ⅰ and Ⅱ,6 patient (23 %) in stage Ⅲ and Ⅳ died of disease progression during follow-up.After 4 cycles of chemotherapy,the FDG-PET was negative in 41%(17/41),positive in 59 %(24/41) respectively.1 patient(6 %)died of disease relapse among 17 patients who were FDG-PET negative, 6 patient (25 %)died of disease progression among 24 patients who were FDG-PET positive during follow-up. Conclusion FDG-PET scanning plays an important role in the pretreatment staging and prediction of the prognosis after 4 cycles of chemotherapy in patients with lymphoma.Thus it may offer the potential for change in treatment paradigms.
