ABSTRACT

La panmielosis aguda con mielofibrosis (PMAF) es un raro desorden hematológico, definido como un subtipo de leucemia aguda. Se reporta un paciente masculino de 31 años de edad con historia de decaimiento marcado, fiebre vespertina y gingivorragia. El examen físico muestra palidez cutáneo mucosas, esplenomegalia ligera y en exámenes complementarios pancitopenia con 5 por ciento de blastos. En el medulograma no se obtuvo material y la impronta sugiere leucemia mieloide aguda no promielocítica. El estudio de inmunofenotipo por citometría de flujo confirma incremento de mieloblastos positivo para (CD34, CD13, CD17, CD117, CD38) y disminuidos en (CD11c y HLA-DR), con una mielofibrosis marcada en biopsia de medula ósea sin la presencia de blastos. Recibe tratamiento de inducción con esquema 3 + 7 (Citosar + Rubidomicina) después del cual el paciente se encuentra en remisión hematológica con persistencia de la fibrosis medular. Posteriormente inicia tratamiento con lenalidomida, Bifosfonatos (Ácido Zoledronico) y se encuentra en remisión hematológica 11 meses después del diagnóstico, hasta marzo 2020. Se realizan estudios de histocompatibilidad (HLA) para trasplante alogénico(AU)


Acute panmyelosis with myelofibrosis (PMAF) is a rare hematologic disorder, defined as a subtype of acute leukemia. A 31-year-old male patient with a history of marked decay, evening fever, and gingivorrhagia is reported. The physical examination showed mucous skin paleness, slight splenomegaly and the complementary examinations showed pancytopenia with 5 percent blasts. In the medullogram no material was obtained and the imprint suggests non-promyelocytic acute myeloid leukemia. Immunophenotype study by flow cytometry confirmed an increase in myeloblasts positive for (CD34, CD13, CD17, CD117, CD38) and decreased in (CD11c and HLA-DR), with marked myelofibrosis in bone marrow biopsy without the presence of blasts. He received induction treatment with a 3 + 7 scheme (Citosar + Rubidomycin) after which the patient was in hematological remission with persistence of spinal fibrosis. Later, he started treatment with lenalidomide, bisphosphonates (Zoledronic Acid) and was in hematological remission 11 months after diagnosis, until March 2020. Histocompatibility studies (HLA) were performed for allogeneic transplantation(AU)

ABSTRACT

OBJECTIVES@#To study the prognostic value of measurable residual disease (MRD) for childhood acute myeloid leukemia (AML) by analyzing MRD-guided risk stratification therapy.@*METHODS@#A total of 93 children with AML were prospectively enrolled in this study. Chemotherapy with the 2015-AML-03 regimen was completed according to the risk stratification determined by genetic abnormality at initial diagnosis and MRD and bone marrow cytology after induction therapy I. Multiparameter flow cytometry was used to dynamically monitor MRD and analyze the prognostic effect of MRD on 3-year cumulative incidence of recurrence (CIR) rate, event-free survival (EFS) rate, and overall survival (OS) rate.@*RESULTS@#The 93 children with AML had a 3-year CIR rate of 48%±6%, a median time to recurrence of 11 months (range 2-32 months), a 3-year OS rate of 65%±6%, and a 3-year EFS rate of 50%±5%. After induction therapy I and intensive therapy I, the MRD-positive children had a significantly higher 3-year CIR rate and significantly lower 3-year EFS and OS rates than the MRD-negative children (@*CONCLUSIONS@#MRD has predictive value for the prognosis of children with AML. Based on the MRD-guided risk stratification therapy, reasonable application of chemotherapy may improve the overall prognosis of children with AML.

ABSTRACT

OBJECTIVE@#To investigate the clinical characteristics of infection in children with acute myeloid leukemia (AML) after high intensive chemotherapy, so as to provide reference for prevention and control of infection.@*METHODS@#56 children diagnosed as acute myeloid leukemia in our hospital from January 2016 to August 2019 were enrolled and retrospectively analyzed, the infection rate, pathogens of disease and common location of infection during the induction and consolidation period were analyzed.@*RESULTS@#The total infection rate of the patients was 93.4%-96.4%, the average of serious infection rate was 16.0%(11.3%-19.6%), and the infection related mortality was 10.7%. Fever of unknown cause was the main reason of infection, while blood flow infections were the most common in severe infection, which were mainly caused by Gramnegative bacteria. The rate of fungal infection was 35.7% during chemotherapy.@*CONCLUSION@#Children with AML shows a high incidence of infection in each stage of chemotherapy. The serious illness caused by blood flow infection and take antifungal drugs to reduce the occurrence of fungal infection in AML patients should be paid attention.

ABSTRACT

OBJECTIVE@#To explore the relationship between effect of induction chemotherapy and prognosis in acute myeloid leukemia (AML) patients.@*METHODS@#The clinical data of 146 adult AML patients treated in Affiliated Hospital of Chifeng University from March 2015 to March 2018 were enrolled and retrospectively analyzed. Day 14 bone marrow biopsy (D14BM) cellularity and blast proportion, daily peripheral blood blast (PBB) clearance rate, time to PBB clearance and etc. were primarily observed after induction chemotherapy. All the patients were divided into Non-relapse survival group, Relapse survival group, Non-relapse death group and Relapse death group according to survival and recurrence situation during 2-year follow-up. The survival of the patients was analyzed by Kaplan-Meier. Univariate analysis of prognostic factors were performed by ordinal Logistic regression, and ROC curve was used to assess the prediction efficiency of those factors for the 2-year overall survival (OS) and relapse of the patients.@*RESULTS@#A total of 138 patients were included since 8 cases failed to be assessed clinically. Their 2-year OS rate was 65.94%. Age of the patients in Non-relapse survival group was lower than that in Relapse death group. The D14BM cellularities in Non-relapse survival group and Relapse survival group were lower than those in Relapse death group (P10%, while it was higher in patients with daily PBB clearance rate >20% than those with clearance rate≤20% (P0.05).@*CONCLUSION@#Bone marrow biopsy results and PBB clearance rate are related to prognosis in AML patients, which can offer certain predictive value in assessing 2-year OS of patients.

ABSTRACT

CXCL12/CXCR4 axis composed of chemokine CXCL12 and its specific ligand CXCR4 can regulate and control the adhesion of leukemia cells to protective bone marrow niche, promote cell survival, and resist apoptosis induced by signal transduction inhibitors and chemotherapeutic drugs. Therefore, CXCL12 /CXCR4 axis has become a new target for the treatment of acute myeloid leukemia. At present, CXCR4 inhibitors that have been developed are in different clinical trials, showing good anti-leukemia effect. In this review, the research advance of CXCR4 inhibitors in the treatment of acute myeloid leukemia is summarized briefly.

ABSTRACT

OBJECTIVE@#To analysis the relationship between different BMI (body mass index) and the clinical characteristics, laboratory examination indexes of newly diagnosed adult patients with acute myeloid leukemia (AML), so as to investigate the effects of BMI to the efficacy of first induction chemotherapy.@*METHODS@#The clinical data of 145 newly diagnosed adult AML patients treated in the First Hospital of Lanzhou University from August 2015 to August 2019 were retrospective analyzed. According to the guidelines for prevention and control of overweight and obesity in Chinese adults, the BMI (kg/m@*RESULTS@#Among the 145 newly diagnosed adult AML patients, there were 71 males and 74 females. The median age was 50 years old(range 18 to 82 years old). There were 21 patients in underweight group (14.5%), 79 patients in normal weight group (54.5%), and 45 patients in overweight and obese group (31.0%). The patients with higher BMI level showed the older in age(P=0.018). There were significant differences in sex between the patients in each group(P=0.035). In overweight and obese patients, the number of male was significantly higher than female. There were no statistical differences in AML classification, comorbidities(Diabetes, hypertension, coronary heart disease), hospital days, whether secondary AML and FLT3 gene mutation among the patients in different BMI groups. There were significant differences in TG of the patients in the different groups, the overweight and obese patients were higher (P=0.007). There were no significant differences in WBC and Hb counts, ALB, TC, HDL, LDL, or LDH between the patients in each BMI group at newly diagnosed. The complete remission rate of the patients in the low body mass group or overweight and obese group were lower than that in the normal body weight group (P=0.035). The rate of documented infection during the first induction chemotherapy were significantly higher for the patients in low body mass group than those in normal weight group or overweight and obese group (P=0.038). There was no statistical difference in chemotherapy regimens, the number of chemotherapy until CR, febrile neutropenia, bleeding, and the time of neutropenia, liver and kidney toxicity among each BMI group. Multivariate analysis showed that overweight and obese (P=0.012) , FLT3 mutation (P=0.015) were the risk factors affecting the CR rate of the patients. And the patients with secondary AML, high-risk type, and newly diagnosed WBC ≥50×10@*CONCLUSION@#In newly diagnosed adult patients with AML, low body mass, overweight and obesity, and FLT3 mutations were the factors reducing the early efficacy of AML patients. There were more adverse reactions induced by chemotherapy in the low body mass group. Therefore, inappropriate BMI level can be a risk factor for assessing the prognosis of adults with newly diagnosed AML.

ABSTRACT

OBJECTIVE@#To explore the impact of induction treatment response on the prognosis of pediatric core binding factor-acute myeloid leukemia (CBF-AML).@*METHODS@#The result of induce reaction and survival data of 157 pediatric CBF-AML patients in our hospital from September 2008 to December 2018 were retrospectively analyzed.The survival rate of the patients with different degrees of morphological remission after induction chemotherapy was comparative analyzed.@*RESULTS@#Among the 157 children with CBF-AML, 113 (72.4%) patients achieved morphologic leukemia-free state (MLFS) after the first course of induction chemotherapy, 153 (98.1%) patients achieved MLFS after the second course of induction chemotherapy. The 5-year event-free survival (EFS) rate and 5-year overall survival (OS) rate of patients with non-remission (NR) status after the first course of induction of chemotherapy was significantly lower than the patients achieved MLFS and the patients achieved partial remission (PR). The 5-year EFS rate and 5-year OS rate of the patients with PR status after the second course of induction chemotherapy were lower than the patients achieved MLFS, but the difference was not statistically significant. Multivariable analyze showed that NR after the first course of induction chemotherapy and myeloid sarcoma were the independent risk factors affecting EFS of the patients. There were six patients with NR status after the first course of induction chemotherapy, in which all of them harbored t(8;21), three of them with sex chromosome deletion, two of them with myeloid sarcoma.@*CONCLUSION@#NR status after the first course of induction chemotherapy was the independent risk factor affecting EFS and OS of CBF-AML patients, it can be taken as an indicator for higher risk stratification. PR status after the first course of induction chemotherapy may not be used as a diagnostic criterion for primary drug resistance.

ABSTRACT

Resumen Objetivo: Describir las características demográficas y clínicas de los pacientes con leucemia mieloide aguda (LMA) no promielocítica, y evaluar la mortalidad y la supervivencia de los niños tratados con protocolo LMA-INC 2004 (modificado de BFM 93) en la clínica de oncología pediátrica del Instituto Nacional de Cancerología, desde su instauración y por un periodo de 10 años y medio de seguimiento (mayo de 2004 a diciembre de 2014). Pacientes y método: Estudio observacional descriptivo retrospectivo de una cohorte con análisis de supervivencia de los pacientes menores de 18 años de edad con diagnóstico LMA tratados con quimioterapia intensiva sin mantenimiento ni trasplante. El análisis de supervivencia se realizó usando el método de Kaplan Meir. Resultados: Se analizaron 41 pacientes con diagnóstico de LMA excepto LMA M3, tratados con protocolo LMA-INC 2004. Se logró remisión completa en el 75,6% de los pacientes. La tasa de recaída fue de 27,4% anual y la tasa de muertes de 20,3% durante el periodo. La supervivencia general acumulada a dos años fue de 60% y a cinco años del 53,5%, con promedio de seguimiento de 4,3 años (3,2 - 5,2 años), y la supervivencia libre de recaída a cinco años fue del 42% con un tiempo promedio de seguimiento de 3,5 años (3,3 - 4,6 años). Conclusión: Los resultados muestran mejoría del 30% en la supervivencia de los pacientes con LMA como resultado de un tratamiento más intenso, que incluye la administración de altas dosis de citarabina y mitoxantrone en la consolidación y la intensificación, y que implica mejoría en los cuidados de soporte.


Abstract Objective: To describe the demographic and clinical characteristics of patients with acute myeloid leukemia; and to evaluate the mortality and survival of children treated with the LMA-INC 2004 protocol (modified from BFM 93) in a pediatric oncology clinic of the Colombian National Cancer Institute (Instituto Nacional de Cancerología de Colombia) between May 2004 and December 2014. Patients and methods: Retrospective descriptive observational study of a cohort with survival analysis of patients aged under 18 years, with a diagnosis of acute myeloid leukemia, who were treated with intensive chemotherapy without maintenance or transplantation. The survival analysis was performed using the Kaplan-Meier method. Results: We analyzed 41 patients diagnosed with myeloid leukemia, except acute myeloid leukemia type M3, who were, treated with the LMA-INC 2004 protocol. Complete remission was achieved in 75.6% of patients. The annual relapse rate was 27.4%; and the death rate 20.3%. Cumulative overall survival at 2 and 5 years was 60% and 53.5% respectively, with an average follow-up of 4.3 years (3.2 - 5.2 years); and the 5-year relapse-free survival was 42%, with an average follow-up time of 3.5 years (3.3 - 4.6 years). Conclusion: The results showed a 30% improvement in the survival of patients with acute myeloid leukemia, attributed to a more intense treatment that included the administration of high doses of cytarabine and mitoxantrone in consolidation and intensification; which implies improvement in supportive care.

ABSTRACT

Introducción: La leucemia mieloide aguda es una enfermedad heterogénea caracterizada por la expansión clonal de precursores indiferenciados que provoca un fallo medular. Objetivo: Analizar la supervivencia de los pacientes adultos con leucemia mieloide aguda no promielocítica tratados con altas dosis de antraciclinas en la inducción. Métodos: Se realizó un estudio analítico, retrospectivo y longitudinal en 53 pacientes adultos menores de 60 años, tratados en el Instituto de Hematología e Inmunología, desde septiembre de 2013 hasta diciembre de 2018. Estos pacientes tenían diagnóstico de leucemia mieloide aguda no promielocítica y recibieron altas dosis de antraciclinas (daunorribicina) en el tratamiento de inducción. Resultados: Las probabilidades de supervivencia global a los 12 meses fue mayor para el grupo de 19 a 29 años con 59 por ciento y más baja para el de 40 a 49 años con 21 por ciento. En cuanto a la probabilidad de supervivencia libre de evento fue de 65 por ciento. Esta resultó mayor para los pacientes de los grupos de 19 a 29 años y de 30 a 39 años con 39 por ciento y 40 por ciento, respectivamente. En el grupo de 40-49 años disminuyó hasta 20 por ciento. En relación con la supervivencia global relacionada con los genes reordenados fue mayor para los pacientes que tenían los genes NPM1 y AML1-ETO y menor para los que tenían los genes FLT3 y BCR/ABL. Conclusiones: Los grupos de edades y las alteraciones genéticas no modifican la supervivencia de los pacientes con leucemias mieloide aguda no promielocítica tratados con dosis altas de antraciclinas(AU)


Introduction: Acute myeloid leukemia is a heterogeneous disease characterized by the clonal expansion of undifferentiated precursors that causes bone marrow failure. Objective: To analyze the survival of adult patients with non-promyelocytic acute myeloid leukemia treated with high doses of induced anthracyclines at induction. Methods: An analytical, retrospective and longitudinal study was carried out with 53 adult patients younger than 60 years, treated at the Institute of Hematology and Immunology, from September 2013 to December 2018. These patients had a diagnosis of non-promyelocytic acute myeloid leukemia and received high doses of anthracyclines (daunoribicin) under induction therapy. Results: The probabilities of overall survival at 12 months were higher for the group of 19- 29 years, accounting for 59%, and lower for the group of 40-49 years, accounting for 21 percent. In the age group of 19-29 years, the probability of event-free survival was 65 percent and the probability of disease-free survival was 44 percent. In the group of 40-49 years, it decreased to 27 percent; while in the group of 50-59 it increased, reaching 80 percent. Regarding overall survival associated with the rearranged genes, it was higher for the patients who had the NPM1 and AML1-ETO genes and lower for those who had the FLT3 and BCR/ABL genes. Conclusions: Age groups and genetic alterations do not modify the survival of patients with non-promyelocytic acute myeloid leukemias treated with high doses of anthracyclines(AU)

ABSTRACT

OBJECTIVES: The outcomes of refractory and relapsed acute myeloid leukemia (AML) patients in developing countries are underreported, even though the similar classic regimens are widely used. METHODS: We conducted a retrospective comparison of "MEC" (mitoxantrone, etoposide, and cytarabine) and "FLAG-IDA" (fludarabine, cytarabine, idarubicin, and filgrastim) in adults with first relapse or refractory AML. RESULTS: In total, 60 patients were included, of which 28 patients received MEC and 32 received FLAG-IDA. A complete response (CR) rate of 48.3% was observed. Of the included patients, 16 (27%) died before undergoing bone marrow assessment. No statiscally significant difference in CR rate was found between the two protocols (p=0.447). The median survival in the total cohort was 4 months, with a 3-year overall survival (OS) rate of 9.7%. In a multivariable model including age, fms-like tyrosine kinase 3 (FLT3) status, and stem-cell transplantation (SCT), only the last two indicators remained significant: FLT3-ITD mutation (hazard ratio [HR]=4.6, p<0.001) and SCT (HR=0.43, p=0.01). CONCLUSION: In our analysis, there were no significant differences between the chosen regimens. High rates of early toxicity were found, emphasizing the role of supportive care and judicious selection of patients who are eligible for intensive salvage therapy in this setting. The FLT3-ITD mutation and SCT remained significant factors for survival in our study, in line with the results of previous studies.

ABSTRACT

OBJECTIVE@#To evaluate the efficacy of decitabine combined with low-dose CEG regimen (DCEG) and decitabine combined with low-dose CAG regimen (DCAG) in the treatment of elderly patients with MDS and MDS-transformed acute myeloid leukemia (AML).@*METHODS@#A prospective study was conducted in 7 medical centers, 45 patients with MDS (≥ 60 years old) and MDS-transformed AML from October 2016 to January 2019 were enrolled, with the median age of 68.5 years old. The risk stratification of patients was poor or very poor, according to IPSS-R score. The treament results of decitabine combined with CEG and decitabine combined with CAG were compared.@*RESULTS@#The comparison of the two regiem showed that the DCEG regimen had advantages on total effective rate (ORR, 86.4% vs 47.8%, respectively), overall survival time (OS) (10.0 months vs 6.0 months, respectively) and progression-free survival time (PFS) (9.0 months vs 3.0 months, respectively). About 50% of MDS patients treated by DCEG regimen achieved PR or CR, with a median OS of 31 months. Multivariate analysis showed that patients with PR or CR after induction therapy and DCEG regimen had longer survival time (31months). The incidence of bone marrow suppression, infection and treatment-related mortality rate were similar between the two groups.@*CONCLUSION@#Decitabine combined with CEG regimen could improve the survival of patients with high-risk MDS and MDS-transformed AML. The conclusion of the reaserch needs to be validated by a larger prospective randomized clinical trial.

ABSTRACT

Introducción: La leucemia mieloide aguda representa el 80 por ciento de las leucemias agudas entre los adultos; el tratamiento de inducción a la remisión, para los pacientes menores de 60 años, está basado en la combinación de antraciclinas y arabinósido de citosina. Objetivo: incorporar las altas dosis de antraciclinas al tratamiento de inducción de la leucemia mieloide aguda no promielocítica en pacientes adultos menores de 60 años. Método: Se realizó un estudio cuasiexperimental en 41 pacientes con este diagnóstico, atendidos en el servicio de Adultos del Instituto de Hematología e Inmunología, desde septiembre del 2013 hasta diciembre del 2016. A todos los pacientes se les realizó estudios morfológicos, inmunológicos, citogenéticos y moleculares al inicio de la enfermedad y ecocardiografía para determinar la fracción de eyección y de acortamiento del ventrículo izquierdo al año de finalizado el tratamiento, para determinar la cardiotoxicidad por el uso de las altas dosis de antraciclinas. Resultados: La distribución por edad fue mayor en el grupo de 46 a 52 años representado por el 26,8 por ciento de los casos y predominó el sexo masculino 60,9 por ciento. En el 85 por ciento de los casos la enfermedad apareció de novo. Según los criterios morfológicos de la clasificación Franco Británico Americana el 31,7 por ciento correspondió a la variante M1, en estrecha relación con las determinaciones por citometría de flujo, para esta variedad. Los genes más comúnmente involucrados fueron el NPM1 y el AML/ETO, para el 24 por ciento y 22 por ciento, respectivamente. El 56,1 por ciento de los pacientes alcanzó la remisión hematológica con un solo ciclo de tratamiento y el 14,6 por ciento, necesitó realizar un segundo esquema de inducción. No se reportaron eventos de cardiotoxocidad por antraciclina durante el tratamiento, ni al año de culminado este. Conclusiones: Con el uso de las altas dosis de antraciclina se lograron remisiones hematológicas, sin toxicidad cardiovascular demostrada(AU)


Introduction: Acute myeloid leukemia represents 80 percent of acute leukemias among adults; the induction treatment to obtain remission in patients under 60 years old is based on the combination of anthracyclines and cytosine arabinoside. Objective: to incorporate the high doses of anthracyclines to the treatment of induction of non-promyelocytic acute myeloid leukemia in adult patients under 60 years of age. Method: We conducted a quasi-experimental study in 41 patients with this diagnosis, at the adult clinic service of the Institute of Hematology and Immunology, from september 2013 to december 2016. Morphological, immunological, cytogenetic and molecular studies were carried out at the beginning of the disease and also echocardiography was performed to determine the ejection fraction and shortening of the left ventricle a year after the end of treatment, to determine cardiotoxicity due to the use of high doses of anthracyclines. Results: The distribution by age was higher in the group of 46 to 52 years represented by 26.8 percent of the cases and the male sex predominated 60.9 percent. In 85 percent of the cases the disease appeared de novo. According to the morphological criteria of the French American British classification, 31.7 percent corresponded to the M1 variant, in close relation with the determinations by flow cytometry, for this variety. The genes most commonly involved were NPM1 and AML / ETO, for 24 percent and 22 percent respectively. 56.1 percent of patients achieved hematological remission with a single treatment cycle and 14.6 percent of patients needed a second induction scheme. No anthracycline cardiotoxicity events were reported during the treatment, nor a year after the treatment, in the patients evaluated. Conclusions: With the use of high doses of anthracycline, have been hematological remissions, without demonstrated cardiovascular toxicity(AU)

ABSTRACT

Introdução: O câncer merece destaque entre as doenças que causam transtornos em adultos e crianças, pois continua sendo um diagnóstico dos mais temidos da atualidade. Vincula-se a um estigma de sofrimento, mutilação e morte, envolvendo uma série de ameaças e dificuldades, que afetam não só a criança, mas sua família como um todo, ao longo do processo de diagnóstico e tratamento Objetivo: Comparar os comportamentos de crianças durante a quimioterapia endovenosa antes e após a aplicação do brinquedo terapêutico instrucional (BTI). Materiais e Métodos: Pesquisa não controlada do tipo "antes e depois", realizada na oncopediatria de um hospital público. Foram avaliadas 10 crianças submetidas a quimioterapia endovenosa. Na coleta de dados, utilizou-se um questionário com questões sociodemográficas, clínicas, comportamentais e reações esboçadas durante o tratamento, antes e após a sessão de BTI. A análise de dados foi feita no programa SPSS, sendo realizado o teste de Mc Nemar, considerando um intervalo de confiança de 95%. Resultados: O câncer infantil mais frequente foi a Leucemia Linfoide Aguda (40%). Dos comportamentos analisados, percebeuse redução significativa após o uso do BTI do comportamento "postura retraída". Conclusão: O BTI representou uma ferramenta importante no controle da ansiedade e sofrimento gerado pelo tratamento quimioterápico endovenoso.


Introduction: Cancer plays a notable role among diseases that afflict adults and children. Its diagnosis is still much feared and connects to a stigma of suffering, mutilation and death. It is related to difficulties and treats that affects not only the child but also his whole family during the long process of diagnosis and treatment. Objective: to compare the behaviors of children during intravenous chemotherapy before and after the application of therapeutic instructional toy (BTI). Materials and methods: Uncontrolled search such as "before and after", held in oncopediatria of a public hospital. Ten children were evaluated, subjected to intravenous chemotherapy. For collection, it was used a questionnaire asking for sociodemographic, clinical and behavioral questions, as well as issues and reactions outlined during treatment, before and after the session of BTI. The data analysis was done in SPSS program, being carried out the Mc Nemar test, assuming a confidence interval of 95%. Results: the most frequent childhood cancer was Acute Lymphoblastic leukemia (40%). Among the behaviors examined, it was significantly reduced after the use of BTI "retracted posture" behavior. Conclusion: the BTI represented an important tool in the control of anxiety and suffering generated by intravenous chemotherapy treatment.
