Caecal leiomyoma detected by whole-body MRI in a patient with Hodgkin lymphoma: first case report

2017

Introduction. Hodgkin Lymphoma (HL) is one of the most curable malignant diseases. Modern treatments, like the combined radiochemotherapy and stem cell transplantation, have increased the number of malignant disease survivors. However, HL survivors are at risk of long-term effects, including the development of solid tumors. Secondary neoplasms are a major cause of late morbidity and mortality following treatment for HL. Case report. We report the case of a male patient, treated for HL by chemotherapy, who developed a large leiomyoma of the cecum one year after the treatment. A whole-body Magnetic Resonance (WBMRI) scan performed during the follow-up allowed the detection of this incidental …

Deoxycoformycin (pentostatin) in the treatment of splenic marginal zone lymphoma (SMZL) with or without villous lymphocytes.

2005

: Background: Splenic marginal zone lymphoma (SMZL) is an infrequent B-cell neoplasm that pursues an indolent course. Signs and symptoms, mostly related to hypersplenism, are successfully managed by splenectomy. However, the therapy of patients who are not fit for a surgical procedure or who relapse after splenectomy, is still an unsettled issue. Patients and methods: We report a phase-II study on 16 patients with SMZL, three therapy naive and 13 pretreated, all showing systemic symptoms or progressive worsening of peripheral cytopenia, who were treated with pentostatin at a dose of 4 mg/m2 every other week for 6–10 wk. In relapsed patients, the median interval between diagnosis and treatme…

Whole-body MRI radiomics model to predict relapsed/refractory Hodgkin Lymphoma: A preliminary study.

2022

Purpose A strong prognostic score that enables a stratification of newly diagnosed Hodgkin Lymphoma (HL) to identify patients at high risk of refractory/relapsed disease is still needed. Our aim was to investigate the potential value of a radiomics analysis pipeline from whole-body MRI (WB-MRI) exams for clinical outcome prediction in patients with Hodgkin Lymphoma (HL). Materials and methods Index lesions from baseline WB-MRIs of 40 patients (22 females; mean age 31.7 ± 11.4 years) with newly diagnosed HL treated by ABVD chemotherapy regimen were manually segmented on T1-weighted, STIR, and DWI images for texture analysis feature extraction. A machine learning approach based on the Extra T…

Primary cutaneous lymphomas in children: A prospective study from the Spanish Academy of Dermatology and Venereology (AEDV) Primary Cutaneous Lymphom…

2021

Background/Objectives Primary cutaneous lymphomas are rare in pediatric patients. The clinical and histopathological manifestations may differ from those in adults. Due to their low frequency and the insidious clinical picture, the diagnosis is usually delayed. The Spanish Primary Cutaneous Lymphoma Registry was initiated in 2016 as a multicenter registry that would allow better insight into the epidemiological, clinical, histopathological, and treatment response characteristics of patients with primary cutaneous lymphomas. Methods We conducted a prospective observational cohort study of primary cutaneous lymphomas in pediatric patients participating in the Spanish Academy of Dermatology an…

Mast Cells and Th17 Cells Contribute to the Lymphoma-Associated Pro-Inflammatory Microenvironment of Angioimmunoblastic T-Cell Lymphoma

2010

Reports focusing on the immunological microenvironment of peripheral T-cell lymphomas (PTCL) are rare. Here we studied the reciprocal contribution of regulatory (Treg) and interleukin-17-producing (Th17) T-cells to the composition of the lymphoma-associated microenvironment of angioimmunoblastic T-cell lymphoma (AITL) and PTCL not otherwise specified on tissue microarrays from 30 PTCLs not otherwise specified and 37 AITLs. We found that Th17 but not Treg cells were differently represented in the two lymphomas and correlated with the amount of mast cells (MCs) and granulocytes, which preferentially occurred in the cellular milieu of AITL cases. We observed that MCs directly synthesized inter…

T cell activation defect in hemodialysis patients: Evidence for a role of the B7/CD28 pathway

1993

T cell activation defect in hemodialysis patients: Evidence for a role of the B7/CD28 pathway. The immunosuppressive effect of chronic renal failure is correlated with an impaired proliferation of peripheral blood leukocytes in vitro . This is mainly due to an impaired function of the accessory cells rather than the T cells. Here we tried to define a missing accessory signal for T cell activation in hemodialysis patients. We substituted cell surface bound molecules by adding tumor cell lines to the in vitro assays that express different patterns of accessory molecules. Cell lines that express the costimulatory B7 molecule reconstituted the activation of patients' cells whereas B7 negative c…

Características clínicas de los pacientes con LNH del Hospital Arnau de Vilanova de Valencia

2001

Objetivo: Conocer las características clínicas de los pacientes con linfoma no Hodgkin (LNH) en general y por subtipos histológicos atendiendo a la clasificación REAL. Pacientes y métodos: Sobre 210 historias clínicas de pacientes con LNH, se seleccionaron 188 con informe anatomopatológico completo que utilizaban la clasificación REAL o si utilizaban otra clasificación se convirtió a ésta por un experto. Recogiéndose las características clínicas del paciente en el momento del diagnóstico con las que se relacionó. Resultados: Se han encontrado diferencias significativas en la distribución por sexos en los linfomas de células del manto, con predominio de los varones (p= 0,005). Los pacientes …
