Therapeutic Choices in Patients with Ph-Positive Chronic Myelogenous Leukemia In Mexico in the Era of Tyrosine Kinase Inhibitors: Stem Cell Transplantation or Tyrosine Kinase Inhibitors? Fifteen Years Later.

Background: Chronic myelogenous leukemia is a neoplastic proliferation of the granulocytic series. In Mexico, chronic myelogenous leukemia accounts for approximately 10% of all leukemias. Tyrosine-kinase inhibitors are considered front-line therapy in high-income countries, whereas allogeneic hematopoietic stem cell transplantation is a recognized therapeutic approach, mainly in low- and middle-income countries.

Prevalence and Consequences of a Delayed Diagnosis in Multiple Myeloma: A Single Institution Experience.

Background: Multiple myeloma (MM) is a disease with unspecific initial symptoms which may lead into a delay in the diagnosis, seemingly increasing the risk of complications and in turn reducing the overall survival (OS).

Objective: To analyze the consequences of a delayed diagnosis of MM in both the OS and the progression-free survival (PFS) of the patients in a single center in México.

Methods: The study included patients with MM who were diagnosed at Clínica Ruiz, Puebla, México, between 1983 and 2022.

Neutrophil to lymphocyte ratio and systemic immune-inflammatory index as markers of response to autologous hematopoietic stem cell transplantation in persons with multiple sclerosis.

Introduction: Biomarkers that help to evaluate the immune system and could be useful in multiple sclerosis (MS) are the neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and systemic immune-inflammatory index (SII). The objective of this work is to evaluate the significance of the SII index, PLR, and NLR before and after transplantation in individuals with MS who underwent autologous hematopoietic stem cell transplant (aHSCT) at a single institution.

Methods: Patients with MS who received an aHSCT between 2017 and 2022 were included in the study.

More about post-transplant cyclophosphamide in haploidentical grafts: full or reduced doses?

Haploidentical hematopoietic can be conducted on an outpatient basis but the two main reasons to accept into the hospital a patient in this setting are complications of the hematological toxicity and/or the cytokine-release syndrome. With the aim of reducing the post-transplant cyclophosphamide-dependent toxicity without compromising its effectivity, attempts to reduce the dose of post-transplant cyclophosphamide have been made: Decreases from the conventional total dose of post-transplant cyclophosphamide (100 mg/Kg) have been explored worldwide, showing that decreasing the total dose to even 50 mg/Kg significantly decreases the toxicity of the procedure without compromising its efficacy, safety and results. We present here the salient data of the attempts to diminish the doses of post-transplant cyclophosphamide which have been done and published worldwide, information that suggests that the conventional doses of post-transplant cyclophosphamide can be significantly reduced thus decreasing the toxicity, without compromising the effectiveness of the procedure, mainly the development of graft host disease.
