ABSTRACT

Background: Moringa peregrina Forssk is a well-known plant in ethnomedicine due to its widespread uses in various diseases like cough, wound healing, rhinitis, fever, and detoxification. The plant seeds contain compounds that are cytotoxic to many cancer cells. During the therapeutic use of plants via the oral route, some compounds present in the plants may be cytotoxic to normal cell lines and red blood cells. Objective: This study was the first report of investigation of the cytotoxic profile on oral cancer, CAL 27, cell line, and hemolytic activities on human erythrocytes of Moringa peregrina seeds ethanolic extract (MPSE). Methods: MPSE was screened for its cytotoxic effect against oral cancer, CAL 27, cell line using 3-(4, 5-dimethylthiazol-2-yl)-2, 5,-diphenyltetrazolium bromide (MTT) assay. The toxicity of MPSE on human erythrocytes was determined by in vitro hemolytic assay. Results: MPSE showed significant anti-proliferative activity against oral cancer, CAL 27 cell line at lower concentrations with half maximal inhibitory concentration (IC50) value of 21.03 µg/mL. At 1,000 µg/ml of MPSE, the maximum hemolysis was found to be 14.3% which is within safer limit. Conclusions: This study revealed a potential anti-oral cancer of MPSE and provided a baseline for its potential use in oral cancer treatment with minimum hemolytic effect on human RBCs.


La Moringa peregrina Forssk es una planta muy conocida en etnomedicina debido a sus usos generalizados en diversas enfermedades como la tos, la cicatrización de heridas, la rinitis, la fiebre y la desintoxicación. Las semillas de la planta contienen compuestos citotóxicos para muchas células cancerosas. Durante el uso terapéutico de las plantas por vía oral, algunos compuestos presentes en ellas pueden ser citotóxicos para las líneas celulares normales y los glóbulos rojos. Objetivo: Este estudio fue el primer informe de investigación del perfil citotóxico sobre el cáncer oral, CAL 27, línea celular, y las actividades hemolíticas en eritrocitos humanos del extracto etanólico de semillas de Moringa peregrina (MPSE). Métodos: Se examinó el efecto citotóxico del MPSE contra la línea celular de cáncer oral CAL 27 mediante el ensayo con bromuro de 3-(4, 5-dimetiltiazol-2-il)-2, 5,-difeniltetrazolio (MTT). La toxicidad del MPSE sobre los eritrocitos humanos se determinó mediante un ensayo hemolítico in vitro. Resultados: MPSE mostró una actividad antiproliferativa significativa contra el cáncer oral, línea celular CAL 27 a concentraciones más bajas con un valor de concentración inhibitoria media máxima (IC50) de 21,03 µg/mL. A 1.000 µg/ml de MPSE, la hemólisis máxima fue del 14,3%, lo que está dentro del límite de seguridad. Conclusiones: Este estudio reveló un potencial anticancerígeno oral de MPSE y proporcionó una base para su uso potencial en el tratamiento del cáncer oral con un efecto hemolítico mínimo en los glóbulos rojos humanos.

ABSTRACT

Introduction: The increased risk of severe and life-threatening toxicity in patients with dihydropyridine dehydrogenase (DPD) deficiency, under treatment with fluoropyrimidines, has been widely studied. An up-to-date overview of systematic reviews summarizing existing literature can add value by highlighting most relevant information and supports decision-making regarding treatment in DPD deficient patients. The main objective of this overview of systematic reviews is to identify published systematic reviews on the association between germline variations in the DPYD gene and fluoropyrimidine toxicity.Methods and analysis: This protocol was developed following the Preferred Reported Items for Systematic Review and Meta-analysis Protocols (PRISMA-P) checklist, and the overview of systematic reviews will be reported in accordance with the PRISMA statement. PubMed, Embase, Scopus, and the Cochrane Library will be searched from inception to 2023. Systematic reviews irrespective of study designs that analyze the association between germline variations in the DPYD and fluoropyrimidine toxicity will be considered. Methodological quality will be assessed using AMSTAR2 checklist (Measurement Tool to Assess Systematic Reviews 2). Two independent investigators will perform the study selection, quality assessment, and data collection. Discrepancies will be solved by a third investigator.(AU)

ABSTRACT

The development of the immune checkpoint inhibitors (ICI) is one of the most remarkable achievements in cancer therapy in recent years. However, their exponential use has led to an increase in immune-related adverse events (irAEs). Gastrointestinal and liver events encompass hepatitis, colitis and upper digestive tract symptoms accounting for the most common irAEs, with incidence rates varying from 2% to 40%, the latter in patients undergoing combined ICIs therapy. Based on the current scientific evidence derived from both randomized clinical trials and real-world studies, this statement document provides recommendations on the diagnosis, treatment and prognosis of the gastrointestinal and hepatic ICI-induced adverse events.(AU)


El descubrimiento de los inhibidores de checkpoint inmunológicos (ICI) es uno de los logros más importantes en los últimos años en Oncología. Sin embargo, su uso en aumento ha conlllevado a un incremento de los efectos adversos inmunomediados (irAEs). Los eventos hepáticos y gastrointestinales incluyen la hepatitis, colitis y síntomas de tracto digestivo superior, que son de los irAEs más frecuentes, con incidencias entre el 2 y 40%, ésta última en paciente tratados con combo de ICI. Basados en la evidencia científica tanto de ensayo clínicos randomizados como de estudio de vida real, este documento de consenso aporta recomendaciones sobre el diagnóstico, tratamiento y pronóstico de los efectos adversos hepáticos y gastrointestinales asociados con la inmunoterapia.(AU)

ABSTRACT

New oncologic treatments, particularly immunotherapy (IT), have revolutionized the treatment of advanced-stage malignant tumors. Immune checkpoint inhibitors are the main form of IT and act by increasing T cell activity and the organism's immune response against neoplastic cells. Targeted therapy is another form of IT that acts by inhibiting oncogenes or inflammation signaling and tumor angiogenesis pathways. However, these mechanisms of tumor destruction can interfere with the host's immune self-tolerance or with the mechanisms of epithelial tissue repair and predispose to immune system-mediated adverse events that can affect multiple organs, including the digestive tract. The gastrointestinal manifestations of damage caused by IT can range from low-grade mucositis to ulceration, and in some cases, necrosis and perforation. Any part of the gastrointestinal tract can be affected, but there is greater involvement of the small bowel and colon, with a pattern similar to that seen in inflammatory bowel disease. The most common clinical manifestation is chronic diarrhea. The differential diagnosis includes enteropathogenic infections, especially those caused by opportunistic microorganisms; adverse drug reactions; and other inflammatory and malabsorption disorders. Treatment is guided by damage severity. Mild cases can be treated with antidiarrheals and rehydration in the outpatient setting; moderate cases with hospitalization, systemic steroids, and temporary suspension of IT; and severe cases with immunosuppressants or biologic agents and definitive suspension of IT.

ABSTRACT

En el último tiempo, la inmunoterapia se ha convertido en una opción terapéutica para diversos tipos de neoplasias, aumentando la sobrevida en muchos casos, pero también los efectos adversos asociados. Existen tres tipos de inmunoterapia utilizados en cáncer: Terapia de células T con receptor de antígeno quimérico (CAR-T), destacando como reacciones adversas el síndrome liberador de citoquinas (CRS) y el síndrome de neurotoxicidad (ICANS); Anticuerpos monoclonales (AcM), cuyos efectos adversos más comunes están relacionados con reacciones de hipersensibilidad; y los Inhibidores de puntos de control inmunitario (ICI) con toxicidad pulmonar claramente reportada. Para un correcto manejo de estas reacciones adversas se requiere un alto índice de sospecha, un adecuado diagnóstico diferencial y un tratamiento oportuno, basado principalmente en corticoides y guiado por criterios de gravedad. Se presenta el caso de un paciente con reacción granulomatosa sarcoidea posterior al uso de Nivolumab.


In recent times, immunotherapy has emerged as a therapeutic option for various neoplasms, significantly improving survival rates in many cases, albeit with associated adverse effects. There are three types of immunotherapy commonly used in cancer treatment: Chimeric Antigen Receptor T-cell Therapy (CAR-T), notable for adverse reactions such as Cytokine Release Syndrome (CRS) and Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS); Monoclonal Antibodies (mAbs), with the most common adverse effects being hypersensitivity reactions; and Immune Checkpoint Inhibitors (ICI), with well-documented pulmonary toxicity. Adequate management of these adverse reactions requires a high index of suspicion, accurate differential diagnosis, and timely treatment, primarily based on corticosteroids and guided by severity criteria. We present a case of a patient with granulomatous sarcoid-like reaction following the use of Nivolumab.

ABSTRACT

Objetivo: evaluar y correlacionar la calidad de vida y la toxicidad financiera de pacientes adultos sometidos a trasplante de células madre hematopoyéticas durante el período de la pandemia de COVID-19. Método: estudio observacional, analítico, realizado con 35 pacientes en un hospital de referencia para trasplante en Latinoamérica. Para la recolección de datos, se utilizaron los cuestionarios Functional Assessment Cancer Therapy Bone Marrow Transplantation y el COmprehensive Score for financial Toxicity. Para el análisis de los datos se utilizaron las pruebas de correlación de Spearman y Mann-Whitney. Resultados: la calidad de vida general durante la COVID-19 mostró un puntaje bajo (67,09/108) con mayor deterioro en el bienestar funcional (14,47/28), bienestar social (16,76/28) y preocupaciones adicionales (23,41/40). Los promedios del grupo alogénico fueron inferiores a los del grupo autólogo en todos los dominios, presentando diferencia significativa en relación a preocupaciones adicionales (p=0,01) y en el índice de evaluación del tratamiento (p=0,04). Se consideró que la toxicidad financiera tenía un impacto leve (22.11/44). Se observó una relación, aunque no significativa, entre la calidad de vida y la toxicidad financiera (p=0,051). Conclusión: la calidad de vida de la muestra fue baja; existe una correlación entre la calidad de vida y la toxicidad financiera, aunque no significativa. Cuanto mayor es la toxicidad financiera, menor es la calidad de vida.


Objective: to evaluate and correlate the quality of life and financial toxicity of adult patients undergoing hematopoietic stem cell transplantation during the COVID-19 pandemic. Method: observational, analytical study, carried out with 35 patients in a reference hospital for transplantation in Latin America. For data collection, the Functional Assessment Cancer Therapy Bone Marrow Transplantation and COmprehensive Score for Financial Toxicity questionnaires were used. Spearman and Mann-Whitney correlation tests were used for data analysis. Results: general quality of life during COVID-19 had a low score (67.09/108) with greater impairment in functional well-being (14.47/28), social well-being (16.76/28) and additional concerns (23.41/40). The means of the allogeneic group were lower than those of the autologous group in all domains, showing a significant difference in relation to additional concerns (p=0.01) and in the treatment evaluation index (p=0.04). Financial toxicity was considered to have a slight impact (22.11/44). There was a relationship, albeit not significant, between quality of life and financial toxicity (p=0.051). Conclusion: the quality of life of the sample was low; there is a correlation between quality of life and financial toxicity, although not significant. The higher the financial toxicity, the lower the quality of life.

ABSTRACT

Esta guía internacional propone mejorar los prospectos de la clozapina en todo el mundo mediante la inclusion de información sobre la titulación del fármaco en función de la ascendencia del paciente. Las bases de datos de reacciones adversas a medicamentos (RAM) sugieren que la clozapina es el tercer fármaco más tóxico en los Estados Unidos de América (EE. UU.) y que produce una mortalidad por neumonía en todo el mundo 4 veces mayor que la correspondiente a la agranulocitosis o la miocarditis. El rango terapéutico de referencia para las concentraciones séricas estables de clozapina es estrecho, de 350 a 600 ng/ml, con potencial de toxicidad y reacciones adversas más fecuentes a medida que aumentan las concentraciones. La clozapina se metaboliza principalmente por CYP1A2 (las mujeres no fumadoras requieren la dosis más baja y los hombres fumadores la dosis más alta). A través de la conversión fenotípica, la prescripción conjunta de inhibidores del metabolismo de la clozapina (incluidos los anticonceptivos orales y el valproato), la obesidad o la inflamación con elevaciones de la proteína C reactiva (PCR), pueden convertir al paciente en un metabolizador lento/pobre (MP). Las personas de ascendencia asiática (de Pakistán a Japón) o los habitantes originarios de las Américas tienen menor actividad de CYP1A2 y requieren dosis más bajas de clozapina para alcanzar concentraciones de 350 ng/ml. En los EE. UU. se recomiendan dosis diarias de 300-600 mg/día. La dosificación personalizada lenta puede prevenir RAM tempranas (incluidos el síncope, la miocarditis y la neumonía). La esencia de esta guía se fundamenta en 6 esquemas de titulaciones personalizadas para pacientes hospitalizados...(AU)


This is the Spanish translation of an international guideline which proposes improving clozapine package inserts worldwide by using ancestry-based: 1) dosing and 2) titration. Adverse drug reaction (ADR) databases suggest clozapine: 1) is the third most toxic drug in the United States (US), and 2) produces worldwide pneumonia mortality four times greater than that of agranulocytosis or myocarditis. For trough steady-state clozapine serum concentrations, the therapeutic reference range is narrow, from 350 to 600 ng/mL with the potential for toxicity and ADRs as concentrations increase. Clozapine is mainly metabolized by CYP1A2 (female non-smokers require the lowest dose and male smokers the highest dose). Poor metabolizer (PM) status through phenotypic conversion is associated with co-prescription of inhibitors (including oral contraceptives and valproate), obesity or inflammation with C-reactive protein (CRP) elevations. People with ancestry from Asia (Pakistan to Japan) or the Americas’ original inhabitants have lower CYP1A2 activity and require lower clozapine doses to reach concentrations of 350 ng/ml. Daily doses of 300-600 mg/day are recommended in the US. Slow personalized titration may prevent early ADRs (including syncope, myocarditis and pneumonia). The core of this guideline consists of six personalized titration schedules for inpatients...(AU)

ABSTRACT

Fundamentos: Desde 2003, el Instituto Nacional del Cáncer (NCI) de los Estados Unidos de América ha sido uno de los líderes mundiales en la clasificación de los Efectos Adversos (EA). Actualmente, los teléfonos inteligentes permiten, entre otras muchas cosas, la monitorización de estos EA de la quimioterapia desde el domicilio para mejorar la seguridad y la calidad de vida de los pacientes. El objetivo de este estudio fue realizar un análisis comparativo descriptivo del contenido de los EA de la aplicación Abeona Health® y la última versión de los CTCAE (Common Terminology Criteria for Adverse Events). Métodos: Se utilizó la app Abeona Health® y la guía CTCAE v5. Posteriormente, se analizaron los EA más recurrentes en el tratamiento quimioterápico, según la NCI y la Sociedad Española de Oncología Médica (SEOM) y, finalmente, si los pacientes podían identificarlos. Resultados: El CTCAE v5 recoge 837 EA, donde 225 son signos y síntomas. El NCI clasifica cincuenta y cinco signos y síntomas como los más recurrentes, y la SEOM dieciséis, de los cuales quince coinciden con el NCI.

Bbackground: Since 2003, the National Cancer Institute (NCI) of the United States of America has been one of the world leaders in classifying adverse effects (AEs). Currently, smartphones allow, among many other things, the monitoring of these AEs of chemotherapy from home to improve the safety and quality of life of patients. The aim was to perform a descriptive comparative analysis of the AEs content of the Abeona Health® app and the latest version of the CTCAE (Common Terminology Criteria for Adverse Events). Methods: The Abeona Health® app and the CTCAE v5 guide were used. Subsequently, the most recurrent AEs in the existing chemotherapy treatment were analysed according to the NCI and the Spanish Society of Medical Oncology (SEOM) and finally, whether patients could identify them. Results: The CTCAE v5 (collects 837 AEs), where two hundred and twenty-five are signs and symptoms. The NCI classifies fifty-five signs and symptoms as the most recurrent, and the SEOM sixteen, of which fifteen coincide with the NCI. The Abeona Health® application has seven AEs, all included in the CTCAE v5. Of these seven, six appear in the NCI lists of most recurrent AEs and four in the SEOM list, all identifiable by the patient. Conclusions: TheAbeona Health® app is considered adequate for the patient participation in their self-care, although somefields could be expanded.(AU)

ABSTRACT

Introducción. Alrededor de 3700 millones menores de 50 años con infección por VHS-1 y 491 millones de personas de 15 a 49 años cursan con infección por VHS-2 en el mundo; sus síntomas, vesículas o ulceras dolorosas reaparecen periódicamente. El tratamiento convencional disminuyó su efectividad en cepas resistentes e inmunodeprimidos. Alternativas terapéuticas con extractos de plantas medicinales y potencial antiviral, como Opuntia soehrensii Brito conocida como "ayrampù" en Bolivia, utiliza infusión de sus semillas como analgésico, antidiabético, hipotensor y febrífugo. En vapores por inhalación para afecciones respiratorias; como tintura tópica en lesiones dérmicas de viruela, sarampión y herpes labial. Objetivo. Evaluar la seguridad preclínica de un gel que contiene el extracto hidro-alcohólico de semillas de Opuntia soehrensii en diferentes dosis, aplicado en la mucosa vaginal de ratas Sprague Dawley. Material y métodos. Se ejecutaron protocolos de toxicidad aguda y subaguda para evaluar la respuesta sistémica, a través de marcadores bioquímicos y de comportamiento, y la respuesta local en mucosa vaginal, mediante estudios histopatológicos, en grupos de animales a los que se aplicó el gel con diferentes concentraciones del extracto de Opuntia soehrensii, comparados con un grupo control y otro que recibió solo el vehículo. Resultados. Se encontró que los indicadores sistémicos de comportamiento y ganancia de peso no mostraron diferencias entre grupos. Los indicadores hematológicos y bioquímicos mostraron resultados fisiológicamente esperados y sin cambios en los grupos de estudio. La citología expuso conservación del fenotipo celular para las fases del ciclo estral en todos los grupos. Los indicadores histológicos de reacción local e integridad celular se distribuyeron de igual manera en los todos los grupos. Conclusión. La aplicación de un gel de Opuntia soehrensii no muestra niveles apreciables de toxicidad local y sistémica, lo que permite recomendar la iniciación de estudios de aplicación clínica.


Introduction. Around 3.7 billion people under 50 years of age are infected with HSV-1 and 491 million people between the ages of 15 and 49 are infected with HSV-2 in the world; his symptoms, vesicles or painful ulcers recur periodically. Conventional treatment decreased its effectiveness in resistant and immunosuppressed strains. Therapeutic alternatives with extracts of medicinal plants and antiviral potential, such as Opuntia soehrensii Brito known as "ayrampù" in Bolivia, uses infusion of its seeds as an analgesic, antidiabetic, hypotensive and febrifuge. In vapors by inhalation for respiratory conditions; as a topical tincture in skin lesions of smallpox, measles and cold sores. Objectives . To evaluate the preclinical safety of a gel containing the hydroalcoholic extract of Opuntia soehrensii seeds in different doses, applied to the vaginal mucosa of Sprague Dawley rats. Material and Methods. Acute and sub-acute toxicity protocols were carried out to evaluate local response in the vaginal mucosa, through histo pathological studies, and systemic responses, through biochemical and behavioral markers, in groups of animals to which the gel with different concentrations of the extract of Opuntia soehrensii was applied, compared with a control group and another that received only the vehicle. Results. It was found that the histological indicators of local reaction and cell integrity were equally distributed in all groups. Cytology showed conservation of the cell phenotype for the phases of the estrous cycle in all groups. The systemic indicators of behavior and weight gain did not show differences between groups. Hematological and biochemical indicators showed results ranged in physiologic parameters, without changes in the study groups. Conclusion. The application of a gel from Opuntia soehrensii does not show appreciable levels of local and systemic toxicity, which makes it possible to recommend the initiation of clinical application studies.

ABSTRACT

OBJECTIVES: Linezolid is an oxazolidin commonly related to the development of haematological toxicity, being renal clearance the major factor involved in the drug clearance. The aim of this study is to evaluate the influence of increased filtration rates in the incidence of linezolid-induced haematological toxicity by comparing augmented renal clearance (ARC) patients versus normal renal function patients. MATERIAL AND METHODS: A retrospective, observational study was conducted on hospitalized patients treated with linezolid for 5 days or more during 2014-2019 period. Patients with a filtration rate of ≥130 mL/min versus reference patients (60-90 mL/min) were compared. Haematological toxicity was defined as a decrease of 25% in platelets, of 25% in haemoglobin, and/or 50% in neutrophils from baseline. Toxicity relevance was classified according to Common Terminology Criteria for Adverse Events v5. Incidence of haematological toxicity between groups was studied by chi-square and Fisher test. Furthermore, percentage diminution of all 3 parameters was calculated and compared by Mann-Whitney test and treatment interruption and transfusion requirements were registered. RESULTS: 30 ARC patients and 38 reference patients were included. Haematological toxicity was observed in 16.66% of ARC patients vs 44.74% of reference patients (P=.014); thrombocytopenia in 13.33% vs 36.84% (P=.051), anaemia in 3.3% vs 10.52% (P=.374) and neutropenia in 10% vs 23.68% (P=.204). Median percentage of platelets decrease in ARC patients was -10.36 (-193.33-62.03) vs 2.68 (-163.16-82.71) in reference patients (P=.333), while haemoglobin decrease was 2.50 (-12.12-25.93) vs 9.09 (-17.72-30.63) (P=.047) and neutrophils decrease was 9.14 (-73.91-76.47) vs 27.33 (-86.66-90.90) (P=.093). 10.5% of normal renal function patients reported at least 1 adverse event grade 3 or superior while 2.6% of them interrupted treatment and 5.2% had transfusion requirements. No major events or interruptions were reported in ARC patients. CONCLUSION: Our findings suggest a lower incidence and clinical relevance of haematological toxicity in augmented renal clearance patients. Thrombocytopenia was the major event in both populations. This might be related to a lower exposure to the drug due to the higher clearance and likely lower therapeutic efficiency. These results suggest a potential benefit of therapeutic drug monitoring on high risk patients.

ABSTRACT

La toxicidad pulmonar por antineoplásicos es muy variable dependiente del grupo far-macológico; la bleomicina es uno de los medicamentos en los que se ha reportado este evento. Este citostático puede lesionar el endotelio pulmonar y el epitelio alveolar para llevar a un proceso inflamatorio y fibrótico del intersticio con repercusiones potencial-mente fatales.A continuación, se presenta un caso de enfermedad intersticial tipo neumonía organi-zada asociada a bleomicina en un paciente de 68 años con diagnóstico linfoma Hodg-kin clásico de tipo esclerosis nodular, con estudio imagenológico normal previo al tratamiento


Antineoplastic pulmonary toxicity is highly variable depending on the pharmacological group; bleomycin is one of the drugs in which this event has been reported. This cyto-static can injure the pulmonary endothelium and the alveolar epithelium to lead to an in-flammatory and fibrotic process of the interstitium with potentially fatal repercussions. The following is a case of interstitial disease type organizing pneumonia associated with bleomycin in a 68-year-old patient diagnosed with classical Hodgkin lymphoma of nodular sclerosis type, with imaging study prior to normal treatment

ABSTRACT

Objetivos linezolid es una oxazolidina frecuentemente implicada en el desarrollo de toxicidad hematológica, siendo el aclaramiento renal el mecanismo mayoritario en su eliminación. Se evaluó la influencia de la hiperfiltración glomerular en la toxicidad hematológica inducida por linezolid en pacientes con aclaramiento incrementado frente a pacientes con función renal normal. Material y métodos se diseñó un estudio observacional y retrospectivo en pacientes hospitalizados, tratados al menos 5 días con linezolid entre 2014 y 2019. Se compararon pacientes con aclaramiento de creatinina incrementado (≥130 mL/min) y normal (60–90 mL/min). Se definió la toxicidad hematológica como el descenso en plaquetas y hemoglobina del 25% y en neutrófilos del 50% frente a los valores basales. Se clasificó el grado de toxicidad según Common Terminology Criteria for Adverse Events v5 y se comparó la incidencia entre ambos grupos mediante Chi-cuadrado y Fisher. Así mismo, se calculó el porcentaje de disminución de los 3 parámetros y su asociación mediante el test de Mann–Whitney y se registraron las interrupciones y transfusiones asociadas.Resultados se evaluaron 30 pacientes hiperfiltradores y 38 normofiltradores. El 16,66% de hiperfiltradores presentó toxicidad hematológica frente al 44,74% (p = 0,014). La trombocitopenia fue del 13,33 vs. 36,84% (p = 0,051), la anemia del 3,3 vs. 10,52% (p = 0,374) y la neutropenia del 10 vs. 23,68% (p = 0,204). La mediana del porcentaje de descenso plaquetario en hiperfiltradores frente a normofiltradores fue del −10,36 (−193,33–62,03) vs. 2,68 (−163,16–82,71) (p = 0,333), de hemoglobina 2,50 (−12,12–25,93) vs. 9,09 (−17,72–30,63) (p = 0,047) y de neutrófilos 9,14 (−73,91–76,47) vs. 27,33 (−86,66–90,90) (p = 0,093). El 10,5% con filtrado normal presentó toxicidad grado 3 o superior, el 2,6% interrumpió el tratamiento y el 5,2% requirieron transfusiones... (AU)
