Hu L, Luo N, Li L, Qiu D, Hu X. A preliminary investigation of the relationship between 18F-FDG PET/CT metabolic parameters and prognosis in angioimmunoblastic T-cell lymphoma. Front Oncol 2023; 13:1171048. [PMID: 37397396 PMCID: PMC10311063 DOI: 10.3389/fonc.2023.1171048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Accepted: 06/05/2023] [Indexed: 07/04/2023] Open
Abstract
Purpose The goal of the study was to determine the prognostic significance of metabolic parameters in baseline 18F-FDG PET/CT images obtained from patients with angioimmunoblastic T-cell lymphoma (AITL). Methods Forty patients with pathologically diagnosed AITL who had baseline 18F-FDG PET/CT between May 2014 and May 2021 were assessed as part of this study. Maximum standardized uptake value (SUVmax), total lesion glycolysis (TLG), and total metabolic tumor volume (TMTV) were obtained and analyzed. In addition, many relevant features were evaluated, including sex, age, staging, International Prognostic Index (IPI), prediction index for T-cell lymphoma (PIT), Ki-67, and so on. Estimates of progression-free survival (PFS) and overall survival (OS) were determined using the log-rank test and Kaplan-Meier. Results The median follow-up was 30.2 months (interquartile range 9.82-43.03). Throughout the follow-up period, 29 (72.5%) deaths occurred and 22 (55.0%) patients made progress. The rates for 2- and 3-year PFS were 43.6% and 26.4%, respectively. The 3- and 5-year OS were 42.6% and 21.5%. For TMTV, TLG, and SUVmax, the cut-off values were 87.0 cm3, 711.1, and 15.8, respectively. Poorer PFS and OS were substantially correlated with high SUVmax and TLG. An increased TMTV suggested a shorter OS. TLG performed independently as OS predictors in multivariate analysis. The risk score for predicting the prognosis of AITL includes the TMTV, TLG, SUVmax, and IPI scores, with 4.5 for TMTV, 2 for TLG, 1.5 for IPI scores, and 1 for SUVmax. Three risk categories of patients with AITL had 3-year OS rates of 100.0%, 43.3%, and 25.0%, respectively. Conclusion Baseline TLG was a strong predictor of OS. Here a new prognostic scoring system for AITL based on the clinical indicators and PET/CT metabolic parameters was constructed, which might make stratification of prognosis easy and also help to individualize treatment.

Abstract
Angioimmunoblastic T-cell lymphoma (AITL) is a specific subtype of peripheral T-cell lymphoma that is challenging to diagnose due to the lack of specific pathological characteristics. This report describes the case of a 56-year-old man with Hodgkin lymphoma in whom the gene rearrangement results were positive for TCRβDB+Jβ1/2. Pathological and immunochemical examinations revealed a diagnosis of lymphoma that was a composite of AITL and focal classical Hodgkin lymphoma. Unfortunately, he died soon after the correct diagnosis was made. This case shows that a combination of immunohistochemistry and gene rearrangement analysis can increase the diagnostic accuracy for AITL. A review of the literature on the misdiagnosis of AITL indicates that this disease progresses rapidly with a high mortality rate. Our experience, in this case, highlights the need for early diagnosis.

Abstract
Aim: To understand the burden of treatment-naive peripheral T-cell lymphoma (PTCL). Methods: A systematic literature review was conducted in November 2020 following best practice methodology. Results: Fifty-five clinical studies were included, mostly investigating cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) or 'CHOP-like' regimens, with combination regimens showing similar effectiveness to CHOP alone. Aside from the combination of brentuximab vedotin + cyclophosphamide, doxorubicin and prednisone (A+CHP), other available treatments showed no statistically significant benefit over CHOP in terms of overall or progression-free survival in overall PTCL patients. The mean monthly cost per patient in the USA ranged from $6328 to $9356 based on six studies. One economic evaluation demonstrated A+CHP to be a more cost-effective treatment option than CHOP. Conclusion: Further research is needed to understand the humanistic and cost impact of frontline treatment for PTCL and its specific subtypes.

Abstract
In this study we aimed to identify a set of prognostic factors for angioimmunoblastic T-cell lymphoma (AITL) and establish a novel prognostic model. The clinical data of 64 AITL patients enrolled to the Fourth Hospital of Hebei Medical University (from 2012 Jan to 2017 May) were retrospectively analyzed. The estimated 5-year overall survival and progression-free survival of this cohort of patients were 45.8% and 30.8%, respectively. Univariate analysis showed that age > 60 years, performance status ≥2, Ann Arbor stage III/IV, lactate dehydrogenase > 250 U/L, serum albumin (ALB) < 30 g/l, Coombs test positive, and Ki-67 rate ≥ 70% were significantly associated with poor prognosis. Multivariate analysis demonstrated that age > 60 years, ALB < 30 g/l, Ki-67 rate ≥ 70%, and Coombs test positive were independent prognosis factors for AITL. Here a new prognostic model, named as AITLI, was constructed using the top 5 significant prognostic factors for AITL prognostic prediction. The AITL patients were stratified into 3 risk groups: low, intermediate, and high risk groups. The new prognostic model AITLI showed better performance in predicting prognosis than the International Prognostic Index (IPI) and the prognostic index for PTCL, not otherwise specified (PIT) that were wisely used to predict the outcome for patients with other subtypes of lymphoma.

EBV status has prognostic implication among young patients with angioimmunoblastic T-cell lymphoma. Cancer Med 2019; 9:678-688. [PMID: 31793218 PMCID: PMC6970042 DOI: 10.1002/cam4.2742] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2019] [Revised: 10/29/2019] [Accepted: 11/15/2019] [Indexed: 12/30/2022] Open
Abstract
Epstein‐Barr virus (EBV)‐positive B cells have been detected in 66%‐86% of patients with angioimmunoblastic T‐cell lymphoma (AITL). However, it remains controversial whether EBV status has an impact on the survival of patients with AITL. In this study, we aimed to reevaluate the impact of EBV on the clinicopathological characteristics of AITL. In particular, we focused on the impact of EBV in younger patients with AITL. In total, 270 cases of AITL were studied. Epstein‐Barr virus‐positive B cells were detected in 191 (71%) cases (EBER+ group). Among the patients who received anthracycline‐based therapy, the EBER status did not affect the overall survival (OS) or progression‐free survival (PFS). In the younger group of AITL (≤60 years), PFS was significantly worse in the EBER− group compared to the EBER+ group (P = .0013). Furthermore, the multivariate analysis identified EBER‐negative status, thrombocytopenia, and elevated serum IgA level as significant adverse prognostic factors for PFS (P < .001, P < .001, and P = .002). Based on these findings, we constructed new prognostic model for the younger group, based on three adverse factors. We classified the patients into two risk groups: low risk (no or 1 adverse factor) and high risk (2 or 3 adverse factors). This new model for younger patients with AITL showed that both OS and PFS were significantly related to the level of risk (P < .0001). In summary, this study showed that, among younger patients with AITL, an EBER+ status significantly improved prognosis compared to an EBER− status. Our new prognostic model should be applicable to younger patients with AITL.

Abstract
The aim of the present study was to analyze features and explore parameters that can help to predict prognosis for angioimmunoblastic T-cell lymphoma (AITL). A total of 117 patients with AITL were retrospectively analyzed. Multivariate analysis showed that β2 microglobulin (β2-M) ≥4.0 mg/L (P = 0.020), rash/pruritus (P = 0.004), performance status (PS) ≥2 (P = 0.006), age >60 years (P = 0.006) and extranodal sites (ENSs) >1 (P = 0.029) were independent risk factors for OS. Rash/pruritus (P = 0.007), age >60 years (P = 0.035) and ENSs >1 (P = 0.006) were independent risk factors for PFS. A novel prognostic model consisting of β2-M, rash/pruritus, PS, age and ENSs >1 was constructed. The model classified patients into 3 risk stratifications: low risk (0 or 1 factor), intermediate risk (2 factors), high risk (≥3 factors) and significantly stratified patients with AITL (P < 0.001). In conclusion, except for PS ≥2, age >60 years and ENSs >1 used in IPI, β2-M and rash/pruritus also indicated adverse prognosis. That we constructed model was commendably prognostic for OS and PFS.

Abstract
We retrospectively analyzed 87 patients with angioimmunoblastic T cell lymphoma (AITL) in Taiwan. The median age was 68 (range 18-89) years. Of these patients, 74 % was at an advanced stage. The most common extra-nodal site involved was bone marrow (36 %). Of these patients, 77 % were International Prognostic Index (IPI) >1 and 79 % had a prognostic index for peripheral T-cell lymphoma (PIT) >1. Of 75 patients who received systemic chemotherapy, the complete remission rate was 60 %, the relapse rate was 47 %, and the 2-year progression-free survival rate was 37.4 %. The 2-year overall survival (OS) rate for all patients was 51.9 %. By multivariate analysis, bone marrow involvement (P < 0.001) and ECOG >1 (P = 0.007) were independent adverse factors for OS. A simplified prognostic index efficiently stratified patients into the following three groups: 2-year OS rates 79.8 % (0 factor), 28.3 % (1 factor), and 10.2 % (2 factors) by using bone marrow involvement and ECOG >1 (P < 0.001). In conclusion, AITL patients were older and had poorer prognosis in Taiwan. Bone marrow involvement, EOCG >1, IPI >1 and PIT >1 had adverse impact on OS. The usefulness of this simplified prognostic index needs further validation.

Abstract
Angioimmunoblastic T-cell lymphoma (AITL) is an aggressive peripheral T-cell lymphoma typically characterized by prominent lymphadenopathy and B-symptoms at the time of presentation, polyclonal hypergammaglobulinemia, autoimmune hemolysis and frequent but highly variable involvement of Epstein-Barr virus (EBV). Lymph node biopsy findings typically include effacement of nodal architecture, polymorphic infiltrate, atypical T-cells (usually CD4+/CD10+/PD1+) and prominent proliferations of high endothelial venules and follicular dendritic cells. However, this classic constellation of pathologic findings is often initially obscured by a prominence of EBV+ B-immunoblasts with or without associated peripherally circulating EBV DNA. Here we document the first reported case of an acute serologic EBV profile (VCA-IgM) in a patient with AITL, and we recommend that clinicians maintain a high index of suspicion for AITL in the appropriate clinical scenario, irrespective of Epstein-Barr related findings.

Abstract
Angioimmunoblastic T-cell lymphoma (AITL) is a rare lymphoid malignancy with dismal prognosis. We conducted a large population-based study using the Surveillance, Epidemiology, and End Results (SEER) database (1973–2010) to determine the temporal survival trends and prognostic factors of AITL patients. A total of 1207 patients with AITL were included in this study, with a median age at diagnosis of 69 years. At presentation, most patients (79.5%) had an advanced-stage disease. Overall survival (OS) probabilities at 2, 5 and 10 years were 46.8%, 32.9%, and 21.9% respectively. Two-year, 5-year, and 10-year disease-specific survival (DSS) rates were 56.1%, 44.0%, and 35.9% respectively.On multivariate analysis, age older than 70 years, advanced-stage disease and male sex were identified adverse predictors for OS and DSS. We failed to find any survival differences among subgroups diagnosed in the 5 periods studied (1992 to 1998, 1999 to 2001, 2002 to 2004, 2005 to 2007, and 2008 to 2010). The current study represents the largest specific series of patients with AITL and the first investigation on temporal changes in survival of AITL patients. There has been no survival improvement for AITL patients over the past two decades. Further investigations are warranted to develop more effective treatment for AITL.

Abstract
To select an appropriate prognostic model in the treatment of mature T- and natural killer (NK) -cell lymphoma (peripheral T-cell lymphoma (PTCL) and NK-/T-cell lymphoma (NKTCL)) is crucial. This study investigated the usefulness of Ann Arbor staging classification International prognostic index (IPI), prognostic index for T-cell lymphoma (PIT) and International peripheral T-cell lymphoma Project score (IPTCLP). Between 2000 and 2009, 176 patients (122 males) with PTCL and NKTCL were diagnosed and treated from a single institute in Taiwan. The correlation between complete response (CR) rate, 3-year overall survival (OS), early mortality rate and four prognostic models was analyzed. Thirty-one patients received hematopoietic stem cell transplantation (HSCT) and were analyzed separately. Three-year OS rate was 34.7%, and anaplastic large-cell lymphoma harbored better outcome than others. IPI score had the lowest Akaike information criterion value (1081.197) and was the best score in predicting OS and early mortality (P=0.009). Ann Arbor stage classification can predict CR rate more precisely (P=0.006). OS was significantly better in patients who received HSCT, even in patients with unfavorable features compared with chemotherapy alone. All prognostic models were useful to evaluate the outcome of patients with PTCL and NKTCL but IPI score did best in predicting OS in PTCL and PIT score in NKTCL. This study also supported the role of HSCT in patients with high-risk or refractory PTCL or NKTCL.

Abstract
The objectives of this study are to explore the clinical features and treatment outcomes and to investigate the correlation between microvessel density (MVD) and survival in patients with angioimmunoblastic T-cell lymphoma (AITL). We retrospectively analyzed clinical and follow-up data of 31 patients treated in two hospitals during 1995-2009 histologically proven AITL. We also assessed MVD in the lump of 31 previously untreated patients using α-CD34 immunohistochemical staining. The median age of the 31 patients was 48 years, eighty percent of the patients were in an advanced stage. 67.7% of them had B symptoms, with the follow-up of 2-13 years, the 5-year overall survival rate was 25.8%. The response rates (RR) of CHOP group and COP (cyclophosphamide, vincristine and prednisolone) group are 76.5 and 75%, respectively, which is no significant difference (P=0.894). RR did not differ whether chemotherapy regimens contained anthracycline or not. The 3-year PFS rate for patients who received COP and CHOP regimen was 25.4 and 35.3% (P=0.562), while 5-year OS rates were 25.0 and 29.4%, respectively (P=0.667). The median PFS for patients with high MVD and low MVD were 15.1 and 30.0 months (P=0.048), while the median OS were 20 and 45 months, respectively (P=0.038). Patients who were sensitive to initial chemotherapy COP regimen have the similar therapeutic effect to CHOP regimen. Patients with high MVD measured in the microenvironment had worse PFS and OS than AITL patients with low expression.
