La amenaza silenciosa de las resistencias bacterianas / The silent threat of bacterial resistance

Las resistencias bacterianas a antimicrobianos representan uno de los principales problemas en la actualidad, encontrándose dentro de las principales causas de muerte en todo el mundo. Latinoamérica y Argentina, lejos de ser una excepción,presentan incidencias crecientes de infecciones por gérmenes resistentes. Cada día, se conocen mejor los mecanismos de resistencia que presentan los bacilos gram negativos y algunos cocos positivos. El problema no surge sólo por el sobreuso de antimicrobianos en la medicina clínica. Su sobreutilización para maximizar los beneficios productivos en la pesca, la ganadería y la agricultura contribuyen a esta situación. Desde la perspectiva de la atención primaria de la salud,consideramos fundamental conocer todos los aspectos que forman parte de esta problemática para intentar mitigar el daño que las resistencias bacterianas generan a nivel global. Argentina se transformó en el primer país de la región y del continente en contar con una ley para prevenir y controlar la resistencia a los Antimicrobianos. Consideramos de vital importancia que se fomenten más y mejores políticas sanitarias de orden público para enfrentar este creciente desafío. (AU)

Nowadays, bacterial resistance to antimicrobials is one of the main problems, being one of the leading causes of death worldwide. Latin America and Argentina, far from being an exception, have an increasing incidence of infections by resistant germs. Every day, the resistance mechanisms of gram-negative bacilli and some positive cocci are better known. The problem does not arise only because of the overuse of antimicrobials in clinical medicine. Its overuse to maximize productive benefits in fishing, livestock, and agriculture also contributes to this issue. From the perspective of primary health care,it is essential to know all the aspects of this problem to mitigate the damage that bacterial resistance generates at a global level. Argentina became the first country in the region and the continent to have a law to prevent and control antimicrobial resistance. We consider it vitally important that more and better public health policies are promoted to face this growing challenge. (AU)

Rare metastatic primary intra-abdominal follicular dendritic cell sarcoma poorly responsive to chemotherapy: A case report

Background@#Follicular dendritic cell sarcoma (FDCS) accounts for about 0.4% of soft tissue sarcomas. Approximately onethird of cases occur in extranodal sites and about 28% of extranodal FDCS may metastasize. Intra-abdominal occurrence is rare and there is limited published data to guide oncologists on how to best treat this malignancy.@*Case Presentation@#This is a case of a 33-year-old female who came in due to incidental finding of a left supraclavicular mass with 2-year history of early satiety. Neck node biopsy revealed a poorly differentiated malignant tumor with positive staining for CD21, CD23, vimentin and S100 consistent with FDCS. PET-CT revealed an intensely FDG-avid large mass in the left upper abdomen with signs of necrosis and mass effect. The patient was given three different chemotherapy regimens that included (1) gemcitabine/docetaxel, (2) single agent doxorubicin and (3) ifosfamide/etoposide, but she progressed on all these. Off-label use of bendamustine was then offered and after just the first cycle, the patient reportedly regained strength and was able to get up from wheelchair with noted interval decrease in size of the cervical mass. Unfortunately, the patient deteriorated and succumbed to infection and multiple pulmonary embolisms.@*Conclusion@#Intra-abdominal FDCS is a rare malignancy with heterogenous outcomes with no uniform treatment strategy at present. Molecular tumor board discussion and multi-disciplinary approach in extranodal FDCS is important in the diagnosis and management. Patients with multiple poor prognostic factors are at risk for tumor recurrence, metastasis, and death.

Management of advanced thymoma presenting with myasthenia gravis in a resource-limited setting: A case report

@#Thymomas are rare tumours which generally account for only 0.2 – 1.5% of mediastinal tumours in adults. Around 40% of patients present with systemic symptoms such as motor weakness due to myasthenia gravis (MG), pure red cell aplasia, and hypogammaglobulinemia. Based on recent guidelines, management of advanced thymoma uses a multimodal approach, which is thymectomy followed by radiotherapy, but not all health care centers have radiotherapy facilities. A 52-year-old woman presented with nasal voice and had difficulty swallowing food. Patient was diagnosed with myasthenia gravis (MG). CT scan with contrast of the thorax showed a heterogenous solid mass in anterior mediastinum. Histopathological examination showed thymoma type B2. Thymectomy followed by seven cycles of platinum-based chemotherapy were done on the patient. Evaluation afterward showed complete remission of thymoma. The patient’s motor weakness improved after the chemotherapy. Post-chemotherapy period was uneventful at six months on follow-up visit. The dosage of acetylcholinesterase inhibitor drug is reduced periodically due to improvement in motor weakness. The case emphasizes how to manage an advanced thymoma with MG with limited therapeutic options, and the importance of multidisciplinary management involving oncologists, surgeons, and neurologists.

Obstacles in combating multidrug resistant tuberculosis in pediatric patients: a scope review / Obstáculos no combate à tuberculose multidroga resistente em pacientes pediátricos: uma revisão de escopo

Abstract Objectives: to identify the scientific evidence on excessively resistant and multidrug resistant tuberculosis in pediatric patients. Methods: this is a scope review of the literature, with a guiding question: "What is the scientific evidence on multidrug-resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis in pediatric patients?". The research used the descriptors: "extensively drug-resistant tuberculosis" OR "multidrug-resistant tuberculosis" AND "pediatrics". The research was carried out in a double-blind manner in the following databases of the Medical Literature Analysis and Retrieval System Online, Regional Office for the Western Pacific's Institutional Repository for Information Sharing, Embase/Elsevier and International Clinical Trials Registry Platform, with a temporal cut-off from 2011 to 2021, sending a final synthesized sample of 18 articles, which evaluated the methodological content through the level of evidence. Results: the results show the lack of research with a high level of evidence related to MDR-TB in children, the lack of adequate dosage of second-line drugs for the pediatric population and the importance of drug sensitivity testing for the cases of treatment Conclusions: it was identified that the obstacles to MDR-TB treatment were concentrated in the lack of detailed protocols, safe drug dosages with a low side effect, and mainly in the social health determinants and disease process involving MDR-TB.

A pesquisa foi realizada de modo duplo-cego nas bases de dados Medical Literature Analysis and Retrieval System Online, Regional Office for the Western Pacific's Institutional Repository for Information Sharing, Embase/Elsevier e International Clinical Trials Registry Platform, com um corte temporal de 2011 a 2021, sendo a amostra final sintetizada de 18 artigos, nos quais avaliou-se o conteúdo metodológico por meio do nível de evidência. Resultados: os resultados mostraram a escassez de pesquisas de alto nível de evidência relacionadas à TB-MDR em crianças, ausência de posologia adequada das drogas de segunda linha para o público pediátrico e a importância do teste de sensibilidade a drogas para o tratamento dos casos. Conclusões: identificou-se que os obstáculos do tratamento TB-MDR se concentraram na ausência de protocolos detalhados, de dosagens medicamentosas seguras e com menor efeito colateral, e, principalmente, nos determinantes sociais do processo saúde e doença que envolvem a TB-MDR.

Abordaje paliativo en enfermedades respiratorias avanzadas / Palliative Approach in Advanced Respiratory Diseases

Las enfermedades respiratorias crónicas avanzadas son prevalentes y producen deterioro de la calidad de vida, en particular la enfermedad pulmonar obstructiva crónica (EPOC), las enfermedades pulmonares intersticiales difusas (EPID) y las enfermedades neuromusculares progresivas con compromiso diafragmático (ENM). Quienes las padecen presentan síntomas persistentes que no son siempre adecuada-mente controlados por los tratamientos recomendados por las guías clínicas de mane-jo. El tratamiento paliativo de los síntomas persistentes es un punto relevante y suelen presentarse barreras para su implementación.Este artículo ofrece una revisión narrativa sobre una perspectiva latinoamericana acerca del rol de los cuidados paliativos en enfermedades respiratorias avanzadas.

Advanced chronic respiratory diseases are prevalent and cause deterioration in qual-ity of life, particularly chronic obstructive pulmonary disease (COPD), diffuse intersti-tial lung diseases (ILD) and progressive neuromuscular diseases with diaphragmatic involvement (NMD). Those who suffer from them usually present persistent symptoms that are not always adequately controlled by the treatments recommended by the clinical management guidelines. Palliative treatment of persistent symptoms is a relevant point, but the pal-liative approach usually presents barriers to its implementation.This article offers a narrative review over Latin American perspective on the role of pal-liative care in advanced respiratory diseases.

Real-world practice of acute leukemia intrathecal chemotherapy administration: A Mexican nationwide survey

ABSTRACT Introduction: Intrathecal chemotherapy is a mainstay component of acute lymphoblastic leukemia treatment. In Mexico, there is a considerable practice variability in aspects, such as the manner of preparation and the administration technique. Objective: Our objective was to describe the different techniques used for the application of ITC and review the existing recommendations in the literature. Method: A cross-sectional, nationwide survey study was conducted by an electronic questionnaire sent to hematologists and oncologists in Mexico. We collected demographic data, personal experience, intrathecal chemotherapy techniques, drug preparation and postprocedural conduct. Results: We received 173 responses. Twenty percent had an anesthesiologist administering sedation and pain management. The platelet count considered safe was 50 × 109/L in 48% of the participants. In 77% (n = 133) of the cases, the conventional needle with stylet used was, 49% did not receive any added diluent in the intrathecal chemotherapy and only 42% were recommended to rest in a horizontal position for more than 30 min. Conclusion: We identified a considerable variation in the administration of intrathecal chemotherapy across the hematologists in Mexico. We discuss the implications and opportunities in reducing the variation in our setting, highlighting the unmet need to establish guidelines that should be evaluated by the Mexican professional society to produce a position paper regarding practice standardization.

Outcomes and survival predictors of Latin American older adults with acute myeloid leukemia: Data from a single center

ABSTRACT Introduction: Acute myeloid leukemia (AML) is most commonly presented in older adults; however, it appears 10 years earlier in Latin American countries. Clinical evolution in older adults from this populations has not been characterized. We analyzed outcomes and survival predictors. Methods: Patients ≥ 55 years old diagnosed with AML at a hematology referral center from 2005 to 2020 receiving intensive chemotherapy (IC), low-dose cytarabine (LDAC) and best supportive care (BSC) were included. Survival analysis included the Kaplan-Meier and Cox models and the cumulative incidence of relapse (CIR). Results: Seventy-five adults were included and the overall survival (OS) was 4.87, 1.67 and 1.16 months, using IC, LDAC and BSC, respectively. The IC led to a higher OS (p < 0.001) and was a protective factor for early death, at a cost of more days spent hospitalized and more non-fatal treatment complications; non-significant differences were found between the LDAC and BSC. Eight (10.7%) patients underwent hematopoietic cell transplantation, with a higher OS (p = 0.013). Twenty (26.7%) patients achieved complete remission; 12 (60%) relapsed with a 6-month CIR of 57.9% in those < 70 years old vs. 86.5% in those ≥ 70 years old, p = 0.034. Multivariate analysis showed the white blood cell count (WBC) and IC had a significant impact on the patient survival, whereas chronological age and the Charlson comorbidity index (CCI) did not. Conclusion: AML in low-middle income countries demands a different approach; the IC improves survival, even with a high incidence of relapse, and should be offered as first-line treatment. Eligibility criteria should include WBC and a multidimensional evaluation. The age per se and the CCI should not be exclusion criteria to consider IC.

Manejo de reações adversas dermatológicas em pacientes submetidos à terapia quimioterápica antineoplásica / Management of dermatological adverse reactions in patients undergoing antineoplastic chemotherapy

Objetivo: o presente estudo tem como objetivo reunir recomendações de cuidados considerando a prevenção e tratamento de lesões de pele induzidas pelo tratamento com quimioterápicos antineoplásicos, de acordo com os estudos e consensos atuais. Metodologia: realizou-se um estudo bibliográfico para levantamento das relações entre os principais fármacos antineoplásicos e suas intercorrências dermatológicas, bem como seus respectivos manejos, para subsidiar a orientação e aconselhamento aos profissionais de saúde que acompanham o paciente oncológico. Resultado: os principais problemas dermatológicos decorrentes do uso de antineoplásicos correspondem às lesões de pele, tais como a descoloração, hiperpigmentação, fotossensibilidade, eritemas, descamação e prurido. Também são recorrentes os efeitos adversos que acometem os pelos e cabelos, resultando em alopecia, e a modificação do crescimento e lesões nas unhas. Tratamentos específicos para cada caso são capazes de amenizar ou reverter os problemas. Conclusão: as reações adversas aos medicamentos envolvendo quimioterapia são frequentes na prática oncológica, e variam em termos de frequência e gravidade, atingindo diversos anexos cutâneos. O adequado manejo destes efeitos melhora a integridade da pele e demais estruturas, proporcionando a esses pacientes a melhoria da autoestima e da qualidade de vida.

Methodology: a bibliographical study was carried out to survey the relationships between the main antineoplastic drugs and their dermatological intercurrences, as well as their respective management, to subsidize the guidance and counselling of health professionals who treat cancer patients. Result: the main dermatological problems arising from the use of antineoplastic agents correspond to skin lesions, such as discoloration, hyperpigmentation, photosensitivity, erythema, scaling and pruritus. Adverse effects that affect hair and body hair are also recurrent, resulting in alopecia, and the modification of growth and lesions on the nails. Specific treatments for each case can alleviate or reverse the problems. Conclusion: adverse drug reactions involving chemotherapy are frequent in oncology practice, and vary in terms of frequency and severity, affecting various skin appendages. Proper management of these effects improves the integrity of the skin and other structures, providing these patients with improved self-esteem and quality of life.

Quality Care in Outpatient Chemotherapy. Design and Validation of the Novel Care Quality Ambulatory Instrument / Cuidado con calidad en quimioterapia ambulatoria. Diseño y validación del nuevo instrumento Care Quality Ambulatory / Cuidado com qualidade em quimioterapia ambulatória. Desenho e validação do novo instrumento Care Quality Ambulatory

Introduction: Neither validated scales nor scales translated into Spanish currently exist to evaluate the perception of quality care in people receiving outpatient chemotherapy, despite their usefulness in evaluating the care provided by nurses and in promoting changes in the delivery of these services. Objective: To design and validate the novel Care Quality Ambulatory-I (CQAMB-I) instrument in outpatient chemotherapy services. Materials and methods: This is an instrument validation study carried out in three stages: literature review, design, and validation of the instrument. Content validation was performed with 14 specialists with at least a master's degree and experience in chemotherapy or quality services; face validation was carried out through a pilot test with 31 participants diagnosed with cancer who received curative chemotherapy, and construct validation was carried out through an exploratory factor analysis with 436 users who received outpatient chemotherapy with curative intent. Results: A total of 15 items were removed in the content validation stage; none were removed in face validation. In construct validation, participants had a median age of 56 years, a median treatment time of 5 months, and breast cancer was the most commonly diagnosed form of cancer. Eighteen models were run, 30 items were removed, 6 factors emerged, and a KMO of 0.80 and a Cronbach's alpha of 0.82 were obtained. Conclusion: The CQAMB-I proved to be valid and reliable for the evaluation of quality care in outpatient chemotherapy services. Additionally, it enabled expanding the conception of such care beyond the attributes of structure, process, and outcome.

Objetivo: Explicar los mecanismos farmacológicos y bioquímicos de la ozonoterapia y su uso en el cáncer como terapia complementaria. Métodos: Se consultaron bases de datos disponibles a través de la red de Infomed. Se utilizaron como palabras clave: cáncer, ozonoterapia y estrés oxidativo. Se seleccionaron artículos originales y de revisión sistemáticos de los últimos diez años que evaluaron la utilización de la ozonoterapia en el tratamiento del cáncer. Resultados: El cáncer es per se una enfermedad inductora de estrés oxidativo. La ozonoterapia respalda su utilización como una terapia adyuvante mediante el preacondicionamiento oxidativo que estimula los sistemas antioxidantes de la célula contra la acción de los radicales libres. Así, se logra neutralizar la acción nociva del estrés oxidativo. El ozono incrementa la eficacia de la radio - quimioterapia y ayuda a reducir los efectos secundarios de estos tratamientos al activar los sistemas antioxidantes de la célula. La ozonoterapia se caracteriza por la simplicidad de su aplicación, bajos costos, alta efectividad y prácticamente ausencia de efectos colaterales en comparación con otros tratamientos adyuvantes. Conclusiones: El uso de la ozonoterapia en oncología como una terapia adyuvante representó un recurso terapéutico de gran valor dado por su perfil de efectividad y seguridad. Su uso podría extenderse para disminuir los efectos secundarios y mejorar la calidad de vida de los pacientes(AU)

Introduction: The clinical use of ozone therapy is increasing every day worldwide and it covers different medical specialties, including oncology. However, in Cuba, the investigations that evaluate the use of ozone therapy in cancer patients are scarce, so scientific studies are needed to demonstrate its clinical efficacy. Objective: To explain the pharmacological and biochemical mechanisms of ozone therapy and its use in cancer as a complementary therapy. Methods: Databases available through Infomed Network were consulted. Key words used were cancer, ozone therapy and oxidative stress. Original and systematic review articles from the last ten years that evaluated the use of ozone therapy in the treatment of cancer were selected. Results: Cancer is, as such, a disease that induces oxidative stress. Ozone therapy supports its use as an adjuvant therapy through oxidative pre-conditioning that stimulates the cell's antioxidant systems against the action of free radicals. Thus, it is possible to neutralize the harmful action of oxidative stress. Ozone increases the efficacy of radio-chemotherapy and helps reducing the side effects of these treatments by activating the cell's antioxidant systems. Ozone therapy is characterized by the simplicity of its application, low costs, high effectiveness and with practically no side effects, compared to other adjuvant treatments. Conclusions: The use of ozone therapy in oncology as an adjuvant therapy represented a therapeutic resource of great value given its effectiveness and safety profile. Its use could be extended to improve tissue oxygenation and thus enhance the efficacy of radiochemotherapy, reducing side effects and improving the patients's quality of life(AU)

Epidemiology and healthcare resource utilization in atopic dermatitis in Colombia: A retrospective analysis of data from the National Health Registry from 2015 to 2020 / Epidemiología y uso de recursos de salud en dermatitis atópica en Colombia: análisis retrospectivo de datos del Registro Nacional de Salud de 2015 a 2020

Introduction: Atopic dermatitis, also known as eczema or atopic eczema, is a chronic inflammatory skin disorder characterized by the presence of pruritus accompanied by itching. In Colombia, epidemiological and healthcare resource utilization information regarding this pathology is limited. Objective: To describe atopic dermatitis epidemiological characteristics and healthcare resource utilization patterns in Colombia. Materials and methods: A retrospective database study using real-world data obtained from the national claims database SISPRO (Sistema de Información para la Protección Social) for the 2015-2020 period was carried out. Sociodemographic (age, and health services delivery), epidemiological (incidence, prevalence, and comorbidities), and healthcare resource utilization data were extracted from the SISPRO database. Results: The epidemiological results showed increased incidence and prevalence of atopic dermatitis in Colombia in the 2018-2019 period compared to 2015-2017. Accordingly, the number of medical consultations (particularly with specialists), the number of procedures, and the number of hospitalizations of patients with atopic dermatitis increased. Topic and systemic corticoids were the most frequently prescribed drugs. Conclusions: Diagnoses of atopic dermatitis in Colombia increased with a concomitant increase in healthcare resource utilization during 2015-2020, which was possibly slowed down by the arrival of the Covid-19. This study may help physicians gaining a better understanding of the disease, improving atopic dermatitis patient management.

Introducción. La dermatitis atópica, también conocida como eczema o eczema atópico, es un trastorno inflamatorio crónico de la piel caracterizado por la presencia de prurito acompañado de picor. En Colombia, la información epidemiológica y de utilización de recursos sanitarios sobre esta enfermedad es limitada. Objetivo. Describir las características epidemiológicas y los patrones de utilización de recursos sanitarios para la dermatitis atópica en Colombia. Materiales y métodos. Se trata de un estudio retrospectivo en el cual se utilizan datos de la práctica clínica real obtenidos del registro nacional SISPRO (Sistema de Información para la Protección Social) en el período 2015-2020. Se extrajeron datos sociodemográficos (incluida la edad y la prestación de servicios de salud), epidemiológicos (incluidos la incidencia, la prevalencia y las comorbilidades) y los correspondientes a la utilización de los recursos sanitarios. Resultados. Los resultados epidemiológicos han demostrado un aumento de la incidencia y prevalencia de la dermatitis atópica en Colombia en el periodo 20182019, en comparación con el periodo 2015-2017. Aumentó el número de consultas médicas (particularmente, con especialistas) de pacientes con dermatitis atópica, el de procedimientos y el de hospitalizaciones. Los corticoides tópicos y sistémicos fueron los medicamentos más prescritos. Conclusiones. Los diagnósticos de dermatitis atópica en Colombia aumentaron con un incremento concomitante en la utilización de recursos sanitarios durante 2015-2020, que posiblemente se vio atenuado por la llegada del Covid-19. Este estudio puede ayudar a los médicos a tener un mejor conocimiento de la enfermedad y, por lo tanto, mejorar el tratamiento de los pacientes con dermatitis atópica.

Desafíos en el manejo del sarcoma de Ewing en una paciente testigo de Jehová / Challenges in the care of Ewing's sarcoma in a Jehovah's Witness patient

El sarcoma de Ewing es una neoplasia de hueso y tejidos blandos, cuyo manejo se relaciona con toxicidad hematológica. Este aspecto representa un desafío médico y ético en los pacientes testigos de Jehová quienes, por sus creencias religiosas, rechazan la aplicación de hemoderivados, con riesgo de que se descontinúe la quimioterapia o de que se utilicen dosis subóptimas. Se presenta el caso de una mujer colombiana de 34 años, testigo de Jehová, con diagnóstico de sarcoma de Ewing con estadificación clínica IIB (T1N0M0) en las regiones maxilar y mandibular izquierdas, tratada con quimioterapia, quien presentó un valor mínimo de hemoglobina de hasta 4,5 g/dl y tuvo indicación quirúrgica como parte del tratamiento. En estos pacientes, la decisión de practicar una transfusión comprende implicaciones éticas que requieren alternativas terapéuticas y un abordaje multidisciplinario.

Ewing's sarcoma is a bone and soft tissue neoplasm, whose management is related to hematological toxicity. This aspect represents a medical and ethical challenge in Jehovah's Witnesses patients, who, due to their religious beliefs, reject the blood component transfusion, with the risk of discontinuing chemotherapy or using suboptimal doses. We present the case of a 34-year-old Colombian woman, Jehovah's Witness, diagnosed with Ewing's sarcoma with clinical stage IIB (T1N0M0) in the left maxillary and mandibular regions, treated with chemotherapy, who presented a hemoglobin nadir of up to 4.5 g/dL, and surgical indication as part of the treatment. In these patients, the transfusion decision has ethical implications that require therapeutic alternatives and a multidisciplinary approach.

Sobrevida en población pediátrica con leucemia linfoblástica aguda tratada con protocolo ALLIC-BFM de quimioterapia. Revisión sistemática / Survival of pediatric population with acute lymphoblastic leukemia treated with ALLIC-BFM chemotherapy protocol. Systematic review

La leucemia linfoblástica aguda constituye la neoplasia infantil más frecuente. Los tratamientos actuales posibilitan más del 80% de supervivencia libre de enfermedad por cinco años. En el 2000, se probó un protocolo de quimioterapia llamado leucemia linfoblástica intercontinental Berlín-Frankfurt-Münster (ALLIC BFM). El proceso investigativo se realizó mediante la metodología PRISMA, con el propósito de sistematizar la información acerca de la supervivencia de los pacientes pediátricos con leucemia linfoblástica aguda tratados con el uso del protocolo de quimioterapia ALLIC BFM en sus versiones de 2002 o 2009. La supervivencia global en pacientes donde se utilizó el protocolo de 2002 fue del 52% al 91,7% y la libre de enfermedad fue del 45% a 83,3%; mientras que, con el uso del protocolo 2009 se reportó una supervivencia global del 71,1% al 90% y la libre de enfermedad fue del 69,4% al 90,3%. Los principales factores que afectaron la supervivencia fueron las complicaciones relacionadas con el tratamiento, los pacientes de alto riesgo y la medicación insuficiente.

Acute lymphoblastic leukemia is the most common childhood neoplasia. Current treatments allow more than 80% disease-free survival for five years. In 2000, a chemotherapy protocol called Berlin-Frankfurt-Münster intercontinental lymphoblastic leukemia (ALLIC BFM) was tested. The investigative process was carried out using the PRISMA methodology. This study aimed to systematize the information about the survival of pediatric patients with acute lympho-blastic leukemia treated with the ALLIC BFM chemotherapy protocol in its 2002 or 2009 versions. 52% to 91.7% of patients showed an overall survival in patients where the 2002 proto-col was used, and disease-free was from 45% to 83.3%; while, with the use of the 2009 protocol, an overall survival of 71.1% to 90% was reported, and disease-free survival was 69.4% to 90.3%. The main factors affecting survival were treatment-related complications, high-risk patients, and insufficient medication.
