Aims and Background Adequate clinical staging of non-Hodgkin's lymphoma patients is essential because only localized disease can be treated satisfactorily. Many imaging procedures are necessary to stage the disease accurately. The objective of this study was to evaluate the efficacy of an anti-lymphoma antibody in the Fab’ fragment form, labelled with 99mTc, to detect malignant lesions. Methods Radioimmunodetection (RAID) with 99mTc-labelled B-cell lymphoma monoclonal antibody IMMU-LL2-Fab’ (LymphoSCAN™; Immunomedics, Morris Plain, NJ, USA) was investigated in 10 patients (5 females and 5 males; age range, 20-72 years) with histologically proved non-Hodgkin's lymphoma. Of the 10 lymphomas, 7 were intermediate grade and 3 were low grade. Whole body images with multiple planar views were obtained at 30 min, 4-6 and 24 h after i.v. injection of 1 mg LL2-Fab’ labelled with 740-925 MBq of 99mTc. SPET of the chest or abdomen was performed in all patients 5-8 h after the immunoreagent injection. Results No adverse reactions were observed in any patient after Mab infusion, and no appreciable changes were seen in the blood counts, renal or liver function tests. A total of 18 of 21 (85.7%) lymphoma lesions were detected by RAID. All the tumor localizations were confirmed by clinical examination and with other imaging techniques, such as CT scan, MRI or gallium scan. In this series of patients no false-positive results were noted. As regards the biodistribution of the immunoreagent, no appreciable bone marrow activity was seen; splenic targeting was demonstrated in all patients; the tumor-to-non-tumor ratios ranged from 1.2 to 2.8 ad measured by the ROI technique; no difference in uptake was noted for different tumor grades. The images obtained 24 h after injection did not reveal new lesions, but areas of doubtful uptake were seen as positive focal areas in the delayed scan. Conclusions LymphoSCAN™ seems to be useful for detection, staging and follow-up of non-Hodgkin's lymphoma patients.

Enhanced Ct

Abstract Aim of the study to evaluate the role of PET/CT in initial diagnosis and staging of lymphoma, and to determine the predictive value of 18F-FDG PET by monitoring the early response and final response after completion of chemotherapy in patients with non-Hodgkin's lymphoma. Patient and Methods our prospective study included 25 patients with pathologically confirmed nonHodgkin Lymphoma diffuse large B cell lymphoma selected from Department of Radiology at Ain Shams University Hospital from January 2019 to March 2020. The patients included in this study performed the followings: Initial PET/CT for staging, interim PET/CT and end of the treatment PET/CT. We performed low dose non enhanced CT scan first, then a whole body PET study followed by diagnostic enhanced whole body CT scan. The whole study took approximately 20-30 minutes. Results PET/CT has greater sensitivity 100% and specificity 68.8% than CT alone for detecting sites of nodal and extra-nodal involvement and for assessment of therapeutic response in non-Hodgkin lymphoma. Conclusion PET / CT is an accurate method for evaluating tumor viability in the post-therapy setting of Non-Hodgkin lymphomas. PET / CT has a significant advantage for the diagnosis of diffusely infiltrating organs without mass lesions or contrast enhancement compared to contrast enhanced CT.

Anti Cd20

PURPOSE: This phase II trial investigated the safety and efficacy of re-treatment with rituximab, a chimeric anti-CD20 monoclonal antibody, in patients with low-grade or follicular non-Hodgkin’s lymphoma who relapsed after a response to rituximab therapy. PATIENTS AND METHODS: Fifty-eight patients were enrolled onto this study, and two were re-treated within the study. Patients received an intravenous infusion of 375 mg/m2 of rituximab weekly for 4 weeks. All patients had at least two prior therapies and had received at least one prior course of rituximab, with a median interval of 14.5 months between rituximab courses. RESULTS: Most adverse experiences (AEs) were transient grade 1 or 2 events occurring during the treatment period. Clinically significant myelosuppression was not observed; hematologic toxicity was generally mild and reversible. No patient developed human antichimeric antibodies after treatment. The type, frequency, and severity of AEs in this study were not apparently different from those reported in the phase III trial of rituximab. The overall response rate in 57 assessable patients was 40% (11% complete response and 30% partial responses). Median time to progression (TTP) in responders and median duration of response (DR) have not been reached, but Kaplan-Meier estimated medians are 17.8 months (range, 5.4+ to 26.6 months) and 16.3 months (range, 3.7+ to 25.1 months), respectively. These estimated medians are longer than the medians achieved in the patients’ prior course of rituximab (TTP and DR of 12.4 and 9.8 months, respectively, P > .1) and in a previously reported phase III trial (TTP in responders and DR of 13.2 and 11.6 months, respectively). Responses are ongoing in seven of 23 responders. CONCLUSION: In this re-treatment population, safety and efficacy were not apparently different from those after initial rituximab exposure.

Periodic Evaluation

AbstractThree cases of primary non-Hodgkin's lymphoma of the larynx are described. Histologically, two tumours belonged to the category of low grade B-cell lymphomas of the small cell type (extranodal marginal zone B-cell lymphoma and lymphoplasmacytoid lymphoma), and the third was classified as a peripheral T-cell lymphoma of unspecified type. The clinical stage was IE in two cases, and IV in another case. In two cases, complete remission was obtained with radical radiotherapy. But in the other case, which was histologically lymphoplasmacytoid lymphoma, the response to radiotherapy was poor, and surgery was required. There was no relapse subsequent to treatment. Primary non-Hodgkin's lymphoma of the larynx is rare. Several reported cases have clinical features similar to those of MALT-type lymphomas arising in other extranodal sites. Although most of the reported cases have been cured with radiotherapy, in some cases dissemination to other extranodal sites may occur. Therefore careful periodic evaluation is imperative.

BackgroundNon-Hodgkin’s lymphoma (NHL) is currently the most common malignancy among people living with HIV (PLWH) in the USA. NHL in PLWH is more frequently associated with oncogenic viruses than NHL in immunocompetent individuals and is generally associated with increased PD-1 expression and T cell exhaustion. An effective immune-based second-line approach that is less immunosuppressive than chemotherapy may decrease infection risk, improve immune control of oncogenic viruses, and ultimately allow for better lymphoma control.MethodsWe conducted a retrospective study of patients with HIV-associated lymphomas treated with pembrolizumab±pomalidomide in the HIV and AIDS Malignancy Branch, Center for Cancer Research, National Cancer Institute.ResultsWe identified 10 patients with stage IV relapsed and/or primary refractory HIV-associated NHL who were treated with pembrolizumab, an immune checkpoint inihibitor, with or without pomalidomide. Five patients had primary effusion lymphoma (PEL): one had germinal center B cell-like (GCB) diffuse large B cell lymphoma (DLBCL); two had non-GCB DLBCL; one had aggressive B cell lymphoma, not otherwise specified; and one had plasmablastic lymphoma. Six patients received pembrolizumab alone at 200 mg intravenously every 3 weeks, three received pembrolizumab 200 mg intravenously every 4 weeks plus pomalidomide 4 mg orally every day for days 1–21 of a 28-day cycle; and one sequentially received pembrolizumab alone and then pomalidomide alone. The response rate was 50% with particular benefit in gammaherpesvirus-associated tumors. The progression-free survival was 4.1 months (95% CI: 1.3 to 12.4) and overall survival was 14.7 months (95% CI: 2.96 to not reached). Three patients with PEL had leptomeningeal disease: one had a complete response and the other two had long-term disease control. There were four immune-related adverse events (irAEs), all CTCAEv5 grade 2–3; three of the four patients were able to continue receiving pembrolizumab. No irAEs occurred in patients receiving the combination of pembrolizumab and pomalidomide.ConclusionsTreatment of HIV-associated NHL with pembrolizumab with or without pomalidomide elicited responses in several subtypes of HIV-associated NHL. This approach is worth further study in PLWH and NHL.
