PURPOSE [(18)F]Fluorodeoxyglucose positron emission tomography (PET) is widely used for the staging and restaging of patients with aggressive lymphoma, but less is known about the utility of PET in patients with follicular lymphoma (FL). In a prospective study, we evaluated the prognostic value of PET performed during treatment and at the end of treatment(More)
The prognostic value of interim positron emission tomography (PET) interpreted according to visual criteria is a matter of debate in diffuse large B-cell lymphoma (DLBCL). Maximal standardized uptake value reduction (ΔSUVmax) may better predict outcome. To compare the prognostic value of both methods, we analyzed PET done at baseline (PET0) and after 2(More)
BACKGROUND The value of (18)F-fluorodeoxyglucose (FDG) PET-CT (PET) imaging in response assessment after first-line rituximab chemotherapy for follicular lymphoma has been documented. We analysed the application of the five-point Deauville scale (5PS; used to score FDG uptake on PET images) in a large cohort derived from three studies, to assess the(More)
OBJECTIVE Endoprostheses were inserted in cancer patients with superior vena cava syndrome to assess their effectiveness as first-choice, initial treatment for relief of symptoms. SUBJECTS AND METHODS Wallstent prostheses (n = 73) of various lengths (5-14 cm; median, 7 cm) and diameters (10-16 mm; median, 16 mm) were inserted in 52 cancer patients (51(More)
PURPOSE Salvage of young patients with follicular lymphoma (FL) after R-CHOP includes salvage immunochemotherapy followed by autologous stem cell transplantation (ASCT). Previous studies dealing with relapsed Hodgkin lymphoma have shown the prognostic value of PET/CT prior to ASCT. METHODS We retrospectively analysed 59 patients with refractory/relapsed(More)
We report a case of a false-positive finding in FDG PET/CT following radiotracer extravasation. A 15-year-old male patient was referred for therapeutic evaluation status post-chemotherapy for a lymphoblastic lymphoma. FDG PET/CT showed discordant findings with a marked decrease in a liver/hepatic hilum uptake, disappearance of a subcutaneous left(More)
BACKGROUND Positron emission tomography (PET) using fluorodeoxyglucose (FDG) has proven to be more sensitive and accurate than other imaging modalities for the detection of distant metastases in patients with melanoma. Sentinel lymph node (SLN) status is the most important prognostic factor in melanoma patients with no evidence of distant metastasis. (More)
A 71-year-old woman was admitted to our hospital with asthenia, weight loss, fever, cognitive impairment and shortness of breath. Physical examination showed hemiparesis and cerebellar ataxia. There was no superficial lymphadenopathy. Blood tests showed raised levels of C-reactive protein and lactate dehydrogenase. Bone marrow aspiration and biopsy were(More)
Hodgkin lymphoma typically presents as a nodal lesion and infrequently involves extra nodal sites. Although cases of primary extra-nodal Hodgkin lymphoma have been reported previously, the reality of the primitive nature of the disease was difficult to authenticate with traditional high resolution imaging techniques, such as computed tomography or magnetic(More)
OBJECTIVE To assess the feasibility of synthesis of O-(2-[(18)F]-fluoroethyl)-l-tyrosine (FET), a new positron emission tomographic (PET) tracer described in several studies but not yet considered standard in management of glioma, in routine practice and to determine FET uptake in a homogeneous group of patients with suspected high-grade glioma.
