Lower access to risk stratification tests and drugs, and worse survival of chronic lymphocytic leukaemia patients treated in public as compared to private hospitals in Brazil: A retrospective analysis of the Brazilian registry of chronic lymphocytic leukaemia.

Chronic lymphocytic leukaemia (CLL) has a highly variable clinical course. In addition to biological factors, socioeconomic factors and health system characteristics may influence CLL outcome. Data from the Brazilian Registry of CLL were analyzed to compare clinical and treatment-related characteristics in patients with CLL, from public or private institutions.

Less Intensive Regimens May Still Be Suitable for the Initial Treatment of Primary Mediastinal B-Cell Lymphoma in Resource-Limited Settings.

Primary mediastinal B-cell lymphoma (PMBCL) is an uncommon disease, consisting of 2-4% of non-Hodgkin lymphomas. Radiotherapy-free DA-EPOCH-R and R-CHOP plus radiotherapy (RT) have been the upfront standard regimens worldwide. However, performing DA-EPOCH-R in resource-constrained settings can be burdensome, especially in low/middle-income countries, where data on PMBCL are still largely unknown.

Outcomes of HIV-associated Burkitt Lymphoma in Brazil: High treatment toxicity and refractoriness rates - A multicenter cohort study.

Background: Although the increased use of combined antiretroviral therapy (cART) has decreased the incidence of lymphomas HIV-associated, Burkitt lymphoma (BL) incidence remains stable. Reported outcomes on HIV-associated BL from developed countries seem to corroborate that the regimens do not need to be tailored to the HIV-positive population.

Materials And Methods: This is a retrospective multicenter cohort study from Brazil, including HIV-positive patients aged 15 years and above diagnosed with BL.

Is it feasible to use granulocyte-colony stimulating factor alone to mobilize progenitor cells in multiple myeloma patients induced with a cyclophosphamide, thalidomide and dexamethasone regimen?

Background: Cyclophosphamide plus thalidomide as induction for multiple myeloma patients eligible for autologous stem cell transplantation may be a limiting factor for cell mobilization. The minimum acceptable mobilized peripheral blood stem cell count to prevent deleterious effects during transplantation is 2.0×10 CD34 cells/kg.

Rhizopus arrhizus and Fusarium solani Concomitant Infection in an Immunocompromised Host.

Neutropenic patients are at risk of the development of hyalohyphomycosis and mucormycosis. Correct identification is essential for the initiation of the specific treatment, but concomitant mold infections are rarely reported. We report one unprecedented case of concomitant mucormycosis and fusariosis in a neutropenic patient with acute myeloid leukemia.

Atypical chronic myeloid leukemia with t(9;22)(p24,11.2), a BCR-JAK2 fusion gene.

We report here on a rare case of BCR-ABL1-negative atypical chronic myeloid leukemia with a t(9;22)(p24;q11.2)translocation and a BCR-JAK2 fusion gene, with resistance to the tyrosine kinase inhibitors imatinib and dasatinib.At two years of follow-up, the patient showed no hematologic response and was submitted to an allogeneic bonemarrow transplantation.

Health care-associated infections in hematology-oncology patients with neutropenia: a method of surveillance.

We present a prospective method of surveillance of health care-associated infection in hematology-oncology inpatients with neutropenia. Incidence rates were calculated on the basis of the number of hospitalized patients, the duration of hospital stay (in days), the number of days of neutropenia, and (in cases of central line-associated blood stream infection) the number of central line-days. We detected 11.

T-cell large granular lymphocytic leukemia: treatment experience with fludarabine.

Objectives: The aim of this retrospective study was to investigate the results of T-cell large granular lymphocytic leukemia treatment with fludarabine by assessing the complete hematologic response, the complete molecular response, progression-free survival, and overall survival.

Methods: We evaluated the records of six patients with T-cell large granular lymphocytic leukemia who were treated with fludarabine as a first-, second-, or third-line therapy, at a dose of 40 mg/m², for three to five days per month and 6 to 8 cycles.

Results: Of the six patients investigated with T-cell large granular lymphocytic leukemia who were treated with fludarabine, five (83.

Disease progression after R-CHOP treatment associated with the loss of CD20 antigen expression.

A case of a follicular lymphoma transformed into a CD20(+) is described which progressed with the loss of CD20 expression after 8 cycles of R-CHOP. This phenomenon is not a rare event and has shown poor prognosis. Our purposes are to describe this event and suggest biopsy in relapsed or progressive disease.

Outpatient treatment with intravenous antimicrobial therapy and oral levofloxacin in patients with febrile neutropenia and hematological malignancies.

The purpose of this study was to evaluate outcomes such as success of the initial therapy, failure of outpatient treatment, and death in outpatient treatment during intravenous antimicrobial therapy in patients with febrile neutropenia (FN) and hematological malignancies. In addition, clinical and laboratory data and the Multinational Association for Supportive Care of Cancer index (MASCC) were compared with failure of outpatient treatment and death. In a retrospective study, we evaluated FN following chemotherapy events that were treated initially with cefepime, with or without teicoplanin and replaced by levofloxacin after 48 h of defervescence in patients with good general conditions and ANC>500/mm3.

A prognostic score for AIDS-related diffuse large B-cell lymphoma in Brazil.

The aim of this study was to evaluate a prognostic score for aids-related lymphoma (ARL). A retrospective study of 104 patients with ARL treated between January 1999 and December 2007 was conducted. Diffuse large B-cell lymphoma (DLBC) was the most observed histological type (79.

Modified Magrath IVAC regimen as second-line therapy for relapsed or refractory aggressive non-Hodgkin's lymphoma in developing countries: the experience of a single center in Brazil.

Background: The purpose of this retrospective study was to investigate the efficacy, toxicity and mobilization rate after modified Magrath IVAC (mIVAC) chemotherapy regimen prescribed in relapsed disease (RD) or primary refractory disease (PRD) in aggressive non-Hodgkin lymphoma (NHL).

Patients And Methods: Twenty-four patients (16 males, 8 females) aged 18-59 years (median age 37 year) were analyzed. The most frequent histopathological subgroup was diffuse large B-cell lymphoma (DLCL-B) (n=21/24), 13 (54%) were considered RD and 11 (46%) PRD.

[Association of angiotensin converting enzyme polymorphism and echocardiographic measures in young siblings of hypertensive parents].

Objectives: To evaluate angiotensin converting enzyme gene (ACE) polymorphism with transthoracic bidimensional echocardiogram of normotensive young medical students, siblings of hypertensive parents comparing them with those with normotensive parents.

Method: We had studied 80 normotensive youngs divided in two groups. Hypertensive parents' normotensive young medical students 40 x Normotensive parents' and normotensive medical students.
