Understanding factors limiting hematopoietic cell transplantation for acute myeloid leukemia patients in Mexico: a comprehensive analysis.

Acute myeloid leukemia (AML) is the most frequent indication for allogeneic hematopoietic cell transplantation (alloHCT) worldwide; social and health system barriers limit its access. We performed an observational retrospective analysis in Mexico to analyze factors limiting alloHCT in fit patients with AML. With a median follow-up of 11.

Cisplatin as a Viable and Secure Alternative to Carmustine in BEAM-Based Conditioning for Autologous Hematopoietic Stem Cell Transplantation in Patients with Lymphoma.

Background: High-dose chemotherapy followed by autologous hematopoietic stem cell transplantation (auto-HSCT) is a standard treatment for relapsed/refractory lymphoma patients. Yet, the widespread use of BEAM is hindered by carmustine accessibility. This study evaluates the efficacy and safety of PEAM (Cisplatin, Etoposide, Cytarabine, and Melphalan) versus BEAM in auto-HSCT for Hodgkin (HL) and non-Hodgkin lymphoma (NHL) patients.

Effect of vitamin C on immune reconstitution after bone marrow transplantation.

Background: Vitamin C is an essential nutrient for the adequate function and maturation of the immune system. In vitro studies show that the development, proliferation, and functioning of T cells requires vitamin C, especially for natural killer (NK) cells. Their deficiency during the acute phase post-transplantation could cause greater morbidity and mortality in these patients.

Consensus in acute myeloid leukemia in Mexico.

Acute myeloid leukemia (AML) comprises a heterogeneous group of hematopoietic cell neoplasms of myeloid lineage that arise from the clonal expansion of their precursors in the bone marrow, interfering with cell differentiation, leading to a syndrome of bone marrow failure. AML is a consequence of genetic and epigenetic changes (point mutations, gene rearrangements, deletions, amplifications, and arrangements in epigenetic changes that influence gene expression) in hematopoietic precursor cells, which create a clone of abnormal cells that are capable of proliferating but cannot differentiate into mature hematopoietic cells or undergo programmed cell death. The diagnosis requires more than 20% myeloid blasts in the bone marrow and certain cytogenic abnormalities.

Building a hematopoietic cell transplantation outcomes registry in Mexico.

The aim of this study was to assess the feasibility of hematopoietic cell transplantation (HCT) data collection using an electronic platform at Mexican centers. Four public centers performing HCT in adults were included. A cloud-based electronic platform in Spanish was developed to allow real-time registration of demographic, clinical, and outcomes variables.

Patients' quality of life: Validation of the functional assessment of cancer therapy-bone marrow transplant (FACT-BMT) instrument for the Mexican population.

Objective: The functional assessment of cancer therapy-bone marrow transplant (FACT-BMT) is a widely used instrument to assess quality of life (QOL) in hematopoietic stem cell transplant (HSCT) patients, but there is little evidence of its validity in Latin American populations. This study evaluated the psychometric properties of the Spanish language version of the FACT-BMT in Mexican patients.

Method: First, the original version was piloted with 15 HSCT patients to obtain an adequate cultural version, resulting in the adaptation of one item.

IFNG +874 A/T is associated with acute lymphoblastic leukemia in Mexican Mestizos.

Acute lymphoblastic leukemia (ALL), the most common type of cancer in children worldwide, has one of the highest incidence rates in Mexico. It is a multifactorial disease and different cytokine single nucleotide polymorphisms (SNP), have been associated with ALL expression. Few studies have been published analyzing IFNG +874 T/A and IL2 -330 G/T in this type of leukemia.

Infectious Complications and Multidrug-Resistant Bacteria in Patients With Hematopoietic Stem Cell Transplantation in the First 12 Months After Transplant.

Background: Hematopoietic stem cell transplantation (HSCT) has been used as treatment in different hematologic and solid malignancies. The aim of this study was to describe the frequency of infectious complications, microbiology, and outcome in patients undergoing HSCT in Mexico during the pre-engraftment period and the impact on mortality rates at 12 months.

Methods: We conducted a retrospective study of all hematologic malignancies that received HSCT from January 2009 and December 2014, at an oncology reference center.

[National guidelines of diagnosis and treatment of the non-Hodgkin lymphoma].

Non-Hodgkin lymphoma comprises a heterogeneous group of haematological malignancies, classified according to their clinic, anatomic-pathological features and, lately, to their molecular biomarkers. Despite the therapeutic advances, nearly half of the patients will die because of this disease. The new diagnostic tools have been the cornerstone to design recent therapy targets, which must be included in the current treatment guidelines of this sort of neoplasms by means of clinical trials and evidence-based medicine.
