Monitoring of Circulating Tumor DNA Predicts Response to Treatment and Early Progression in Follicular Lymphoma: Results of a Prospective Pilot Study.

Purpose: Follicular lymphoma (FL) is the most frequent indolent non-Hodgkin lymphoma. Around 20% of patients suffer early disease progression within 24 months (POD24) of diagnosis. This study examined the significance of circulating tumor DNA (ctDNA) in predicting response to therapy and POD24 in patients with FL.

Long-term follow-up of patients with nodular lymphocyte predominant Hodgkin lymphoma: A report from the Spanish Lymphoma Oncology Group.

Nodular lymphocytic predominance Hodgkin lymphoma (NLPHL) is a very uncommon subtype of Hodgkin lymphoma (HL), representing approximately 5% of all HL cases, with an incidence of 0.3/100,000 cases per year and with unique characteristics which distinguish it from classic Hodgkin lymphoma. Given its low frequency, there is a lack of prospective randomized studies to inform practice, the accumulated experience of academic groups being the main source of relevant information for the management of these patients.

mRNA in exosomas as a liquid biopsy in non-Hodgkin Lymphoma: a multicentric study by the Spanish Lymphoma Oncology Group.

Purpose: To determine the feasibility of mRNAs ( and ) in exosomes of plasma as a liquid biopsy method for monitoring and prognostic evolution in B-cell lymphomas.

Patients And Methods: Exosomes were isolated from 98 patients with B-cell Lymphoma and 68 healthy controls. mRNAs were analyzed by quantitative PCR.

Prognostic value of event-free survival at 12 and 24 months and long-term mortality for non-Hodgkin follicular lymphoma patients: A study report from the Spanish Lymphoma Oncology Group.

Background: Relatively few studies have analyzed the mortality of follicular lymphoma (FL) patients in comparison with a sex- and age-matched general population. This study analyzed the overall survival (OS) of patients with FL and compared their survival with the expected survival of a general population.

Methods: Patients diagnosed with FL were prospectively enrolled from 1980 to 2013.

Impact of treatment in long-term survival patients with follicular lymphoma: A Spanish Lymphoma Oncology Group registry.

Background: Follicular lymphoma is the second most common non-Hodgkin lymphoma in the United States and Europe. However, most of the prospective randomized studies have very little follow-up compared to the long natural history of the disease. The primary aim of this study was to investigate the long-term survival of our series of patients with follicular lymphoma.

Primary Breast Lymphoma: Analysis of 55 Cases of the Spanish Lymphoma Oncology Group.

Introduction: Primary breast lymphoma is a rare form of localized extranodal lymphoma, which affects the mammary glands unilaterally or bilaterally, and can also affect the regional lymph nodes.

Materials And Methods: We reviewed 55 patients, with disease stages IE and IIE, diagnosed in 16 Spanish institutions between 1989 and 2016. A serial of clinical variables and treatment were collected, and overall survival (OS) and progression-free survival (PFS) were calculated.

Consolidation treatment with Yttrium-90 ibritumomab tiuxetan after new induction regimen in patients with intermediate- and high-risk follicular lymphoma according to the follicular lymphoma international prognostic index: a multicenter, prospective phase II trial of the Spanish Lymphoma Oncology Group.

Relapse is the main cause of therapeutic failure in follicular lymphoma (FL). We set out to evaluate the role of consolidation with Yttrium-90 ibritumomab tiuxetan in patients with intermediate- and high-risk FL after four cycles of CHOP-R (cyclophosphamide, doxorubicin, vincristine, prednisone, rituximab) and two cycles of CHOP. Thirty patients were included.

Are there any significant variations in the clinical or histological presentation of lymphoid pathologies over the course of time in Spain?

Introduction: Little data is available concerning variations in the clinical characteristics of lymphoid neoplasms at presentation. We decided to investigate whether any variations in these characteristics had occurred in Spain during the last few years.

Materials And Methods: The GOTEL group database is an archive of all new lymphoma cases, regardless of their histological subtype, diagnosed in the hospitals within the group.

Clear-cell adenocarcinoma of vesical origin: a case study of metastatic disease treated with chemotherapy.

Vesical clear cell adenocarcinoma is an uncommon tumour. The description of nearly all published cases focuses on histological issues, providing few clinical particulars and limited followup. The treatment choice is resection.
