Prognostic value of interim 18F-FDG PET/CT in diffuse large B-cell lymphoma

Objective: Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease. The prognostic factor currently used is not accurate enough to predict the outcomes of patients with DLBCL. The prognostic significance of interim PET/CT in DLBCL remains controversial. The aim of this study is to determine the predictive value of interim 18F-FDG PET/CT after first-line treatment in patients with DLBCL. Methods: Thirty-two patients with DLBCL underwent baseline, interim and post-treatment 18F-FDG PET/CT scans. Imaging results were analyzed for the survival of patients via software SPSS 13.0, retrospectively. Results: Thirty-one of the 32 patients were treated with R-CHOP regimen, and interim 18F-FDG PET/CT of 24 patients was performed after 2 cycles of treatment. After a median follow-up period of 16.7 months, the 2-year progression-free survival (PFS) rates were significantly different between the groups above and below SUV max cut-off value of 2.5 (P=0.039). No significant differences were found in the 2-year PFS rates if SUV max cut-off values were set as 2.0 and 3.0, respectively (P=0.360; P=0.113). Conclusions: Interim PET/CT could predict the prognosis of DLBCL patients with the SUV max cut-off value of 2.5, but more clinical data should be concluded to confirm this conclusion.     

A novel prognostic model for extranodal natural killer/T-cell lymphoma

Natural killer (NK)/T-cell lymphoma is a rare neoplasm with heterogeneous clinical behaviors. This study aimed to devise a prognostic model specifically for extranodal NK/T-cell lymphoma, providing risk stratification in affected patients. A total of 146 patients newly diagnosed with extranodal NK/T-cell lymphoma were retrospectively analyzed. Independent predictors of survival were determined by Cox regression analysis. The estimated 5-year overall survival rate for all patients was 41.9%. Both the International Prognostic Index and Korean NK/T-cell lymphoma Prognostic Index were prognostic in univariate analysis. The majority of our patients were in the low-risk International Prognostic Index and Korean NK/T-cell lymphoma Prognostic Index category (with no or one adverse factor), but both of these two prognostic models had no discriminating power within the subgroup of these patients. Absolute lymphocyte count at diagnosis, B symptoms, and advanced stage were independently predicted poorer survival. Cox analysis yielded a novel prognostic model based on these three parameters that categorized patients into one of three risk groups: Group 1 (57 cases, 39.0%), no adverse factors; Group 2 (43 cases, 29.5%), one adverse factor; and Group 3 (46 cases, 31.5%), two or three adverse factors. Five-year overall survival was 71.6% for Group 1, 55.5% for Group 2, and 0% for Group 3 (P < 0.0001). The novel prognostic model balanced the distribution of patients into different risk groups with better predictive discrimination. It may be useful to stratify patients with extranodal NK/T-cell lymphoma into different risk groups and provide more information for treatment selection.     

Risk stratification in extranodal natural killer/T-cell lymphoma

Extranodal natural killer/T-cell lymphoma (ENKL), a subtype of natural killer/T-cell malignancies, is a rare subset of lymphomas with significant biological and clinical heterogeneity. The prognosis of ENKL is variable and therapeutic approaches are not well established. The optimal dose, combination, and sequence of radiotherapy and chemotherapy are evolving, as is the role of stem cell transplantation. Radiotherapy is an essential component of therapy for early-stage disease. The clinical course of advanced disease is highly aggressive, with frequent chemotherapy resistance and a poor prognosis. For relapsed disease, asparaginase-based regimens have provided encouraging results and are currently under investigation in the frontline setting. Our article discusses the key aspects of biology, pathogenesis and clinical presentation that contribute to the heterogeneity, and proposes a stratified approach to the treatment of ENKL based on clinical, pathologic and biologic risk factors. Although considerable advances have been made in our understanding of the biology and prognosis of this lymphoma, it remains critical that all patients with a diagnosis of ENKL are enrolled and treated in clinical trials so that optimal therapies can be identified.     

结外NK/T细胞淋巴瘤治疗进展

结外NK/T细胞淋巴瘤（ENKTL）是非霍奇金淋巴瘤中较为罕见的亚型,东亚地区比西方国家多见。主要发生在鼻腔或鼻窦区,皮肤受累少见。基于ENKTL的发病机理,几乎所有患者的淋巴瘤细胞中都存在EB病毒。EBV-DNA拷贝数与肿瘤负荷密切相关,并能预测ENKTL预后。由于P-糖蛋白的表达,使细胞产生耐药性,ENKTL预后较差。近年来,新的治疗方法的研究延长了ENKTL患者的生存期。对于局限期ENKTL放疗联合化疗已取得良好的疗效。对于晚期复发难治ENKTL以L-门冬酰胺酶为基础的化疗方案显著提高治疗有效率。有文献报道,造血干细胞移植在ENKTL的治疗中取得了重要地位,而靶向药物的出现为晚期ENKTL提供了新选择。本文综述了ENKTL的治疗进展。

The value of [(18)F]fluorodeoxyglucose positron emission tomography/computed tomography in extranodal natural killer/T-cell lymphoma

PurposeTo our knowledge, there are no published data pertinent to the use of [¹⁸F]fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) in patients with natural killer (NK)/T—cell lymphoma. The purpose of this study was to assess the value of FDG PET/CT in this aggressive type of non-Hodgkin lymphoma.Patients and MethodsAll patients with NK/T-cell lymphoma referred for FDG PET/CT at our institution from July 2001 to July 2006 were retrospectively studied. PET/CT examinations were blindly reviewed by 2 experienced readers. The results were compared with the status of the disease, which was determined after evaluation of biopsy, laboratory, clinical and conventional imaging examination, and follow-up results. PET/CT results were thereby classified as true-positive, true-negative, false-positive, or false-negative. The degree of FDG uptake in the positive lesions was semiquantified using maximum standard uptake value (SUV_max).ResultsTwenty-one PET/CT examinations were performed in 10 patients with NK/T-cell lymphoma. For nasal disease, PET/CT was true-positive in 5 cases, true-negative in 15 cases, and positive but unconfirmed in 1 case. For extranasal disease, PET/CT was true-positive in 3 cases, true-negative in 16 cases, and false-negative in 2 cases. The mean SUV_max in PET-positive lesions in nasal cavities or paranasal sinuses was 16 gm/mL (range, 5–25 gm/mL; median, 19.3 gm/mL). In extranasal disease, the mean SUV_max was 10.9 gm/mL (range, 4.6–34.1 gm/mL; median, 5.6 gm/mL).ConclusionViable NK/T-cell lymphoma is intensely FDG hypermetabolic. PET/CT appears to be sensitive for the detection of disease in the nasopharynx and, to a lesser extent, in extranasal sites.     

Prognostic significance of 18F-FDG PET/CT in patients with colorectal cancer liver metastases after hepatectomy
