RESUMO
Introducción: El sarcoma de Ewing es un tumor maligno de alto grado con localización principalmente ósea; se han reportado aproximadamente 12% con presentación extra-esquelética. Actualmente, existen alrededor de 20 casos descritos en la literatura con origen mediastinal y 10 casos con origen pulmonar. Caso clínico: Se presenta el caso de una mujer de 25 años con un mes de disnea y dolor torácico, con el hallazgo de derrame pleural masivo y tumoración mediastinal en hemitórax derecho. Se le realiza toracotomía anterior bilateral con esternotomía transversa de Clamshell, con resección parcial que demuestra, por patología, sarcoma monomórfico de alto grado e inmunohistoquímica concluyente de sarcoma de Ewing. Conclusión: Este caso es una entidad rara y conlleva un reto diagnóstico para el clínico; sin embargo, debe sospecharse considerando la presentación clínica y radiológica del paciente, buscando incrementar la tasa de supervivencia mediante el diagnóstico y tratamiento oportuno.
Introduction: Ewing's sarcoma is a high-grade malignant tumor with mainly bony lo-calization; approximately 12% have been reported with extraskeletal presentation. Currently, there are about 20 cases described in the literature with mediastinal origin and 10 pulmonary cases. Case Report: We present the case of a 25-year-old woman with one month of dysp-nea and chest pain, with massive pleural effusion and mediastinal tumor in the right hemithorax who underwent bilateral anterior thoracotomy with Clamshell transverse sternotomy, with partial resection demonstrating, by pathology, high-grade monomorphic sarcoma and conclusive immunohistochemistry of Ewing's sarcoma. Conclusion: This case is a rare entity and involves a diagnostic challenge for the clinician; however, it should be suspected considering the clinical and radiological presentation of the patient, seeking to increase the survival rate through timely diagnosis and treatment.

Currently, there is limited data available comparing Primary Mediastinal Large B-cell Lymphoma (PMBL) and mediastinal Hodgkin disease, nodular sclerosis type (HDNS). This is a retrospective cohort study that compares the clinical features, histology through immunohistochemistry (IHC) and treatment outcomes of 19 cases of PMBL and 39 cases of HDNS diagnosed over 13 years at a single institution in San Juan, PR. Superior Vena Cava syndrome (SVCS) and elevated Lactate Dehydrogenase (LDH) levels were more frequently seen in the PMBL cohort. At the median follow-up visit, of 74 months, no significant difference was seen in overall survival or progression free survival between PMBL and HDNS. Almost all of the relapses in the PMBL group occurred within 12 months of diagnosis. Our data suggests that PMBL and HDNS differ in their clinical presentation and have a favorable prognosis.

The inflammatory myofibroblastic tumour, although very rare, must be considered in the differential diagnosis of intracardiac masses in children as it has systemic implications. We present a case of an infant whose diagnosis was suspected on clinical basis and echocardiogram, but the anatomopathological analysis with immunohistochemical study was essential for the conclusion of the histological type and orientation of the clinical follow-up.

Introducción: El síndrome de vena cava superior (SVCS) es una patología poco frecuente, asociado en la mayoría de los casos a neoplasias de origen maligno; la cual en estadios avanzados representa una urgencia médico-oncológica que compromete la vida del paciente. Propósito de la revisión: El objetivo de la revisión es delinear el rol de las diferentes alternativas quirúrgicas y percutáneas para el tratamiento del SVCS. Buscamos reportes en donde se incluye los resultados de mejor supervivencia para los distintos tratamientos actuales. Recientes hallazgos: La literatura médica describe tratamientos como la radioterapia, la quimioterapia, el bypass, la terapia endovascular y la reconstrucción vascular para el manejo del SVCS, sin embargo, no todos responden con la misma eficacia al momento de presentarse una urgencia vital por SVCS; esto producto de los factores intrínsecos y extrínsecos del paciente. Dentro de los factores extrínsecos destaca la condición social la cual, se convierte en un reto al momento de realizar un manejo integral del paciente en ciudades fronterizas, donde los datos que conoce el médico sobre el paciente son limitados o el paciente no tiene un diagnóstico previo que permita orientar el manejo. Conclusiones: El punto de partida del tratamiento del paciente con SVCS consiste en diferenciar la emergencia y la estabilidad mediante la tabla de clasificación de gravedad. En casos emergentes se tiene 2 alternativas: la terapia endovascular y la radioterapia. El abordaje quirúrgico con Baypass está contraindicado y el tratamiento definitivo con reconstrucción vascular con prótesis tiene ventajas y desventajas que deben definirse en forma individual considerando la etiología del cáncer asociado.
Introduction: Superior vena cava syndrome (SVCS) is a rare pathology, associated in most cases with neoplasms of malignant origin; which in advanced stages represents a medical-oncological emergency that compromises the patient's life. Purpose of the review: The objective of the review is to outline the role of the different surgi-cal and percutaneous alternatives for the treatment of SVCS. We look for reports that include the best survival results for the different current treatments. Recent findings: The medical literature describes treatments such as radiotherapy, chemo-therapy, bypass, endovascular therapy and vascular reconstruction for the management of SVCS, however, not all respond with the same efficacy at the time of a vital emergency. by SVCS; this product of the intrinsic and extrinsic factors of the patient. Among the extrinsic fac-tors, the social condition stands out, which becomes a challenge when carrying out an integral management of the patient in border cities, where the data that the doctor knows about the patient is limited or the patient does not have a previous diagnosis. to guide management. Conclusions: The starting point of the treatment of the patient with SVCS consists in differentiating the emergency and the stability by means of the severity classification table. In emergent cases there are 2 alternatives: endovascular therapy and radiotherapy. The surgical approach with Baypass is contraindicated and the definitive treatment with vascular reconstruc-tion with a prosthesis has advantages and disadvantages that must be defined individually considering the etiology of the associated cancer.

Introducción: el síndrome de vena cava superior resulta de la obstrucción del flujo sanguíneo a través de este vaso. Casi la totalidad de los casos en la actualidad se asocian con tumores malignos. Existen controversias acerca del manejo apropiado de este cuadro. Actualmente, las terapias endovasculares son consideradas de elección. Materiales y métodos: se recolectaron y describieron, a partir de datos de la historia clínica electrónica, los casos de pacientes mayores de 18 años internados de forma consecutiva, que desarrollaron el síndrome en el Hospital Italiano de Buenos Aires en 2021. Se constataron las características basales, los tratamientos recibidos y los desenlaces clínicos intrahospitaliarios de cada uno de ellos. Resultados: un total de cinco pacientes fueron incluidos en el presente estudio y seguidos durante su instancia intrahospitalaria. Todos los casos descriptos fueron secundarios a enfermedades oncológicas. La mayoría de los pacientes presentaron un cuadro de moderada gravedad según las escalas utilizadas. En cuatro de cinco pacientes se optó por terapias endovasculares y dos de ellos fallecieron durante la internación. Discusión: existen controversias respecto del tratamiento óptimo del síndrome de vena cava superior, y heterogeneidad en la práctica clínica. Los estudios futuros deberían centrarse en identificar a aquellos pacientes que más probablemente se beneficien de las estrategias terapéuticas endovasculares, anticoagulantes o antiagregantes. (AU)
Introduction: superior vena cava syndrome results from an obstruction of blood flow through this vessel. Currently, almost all cases are associated with malignancies. There are controversies about the optimal management of this syndrome. Endovascular therapies are considered the first-line therapy. Material and methods: we collected clinical, laboratory and pharmacological data from patients admitted at the Hospital Italiano de Buenos Aires, between January 1st and November 1st 2021 with a diagnosis o superior vein cava syndrome. Baseline characteristics, treatment strategies and clinical outcomes were recorded. Results: a total of five patients were included in the present study. All cases were malignancy-related. Most of the patientsdeveloped moderate symptoms. Four out of five patients were treated with endovascular therapies and two patients died during hospitalization. Discussion: controversies regarding optimal management of the superior vena cava syndrome remain. Future research should focus on identifying those patients who are most likely to benefit from endovascular, anticoagulant or antiplatelet therapeutic strategies. (AU)

Las urgencias oncológicas son complicaciones comunes de la evolución natural del tumor o de su manejo. Algunas pueden presentarse de manera sutil y ser pasadas por alto, lo que aumenta la morbimortalidad. El objetivo de esta revisión narrativa es recopilar información actualizada de las principales complicaciones oncológicas, para ello se realizó una revisión de artículos originales, revisiones sistemáticas y narrativas en bases de datos como Scopus, SciELO, PubMed, ScienceDirect y en el buscador Google Scholar. Se seleccionaron 63 referencias que mostraran información relevante acerca de las urgencias oncológicas planteadas para el desarrollo del artículo. En la revisión se discute que las complicaciones pueden clasificarse de acuerdo con su origen en infecciosas (neutropenia febril), metabólicas (síndrome de lisis tumoral e hipercalcemia maligna) y obstructivas (síndrome de vena cava superior, obstrucción intestinal, compresión medular y taponamiento cardiaco). El diagnóstico requiere un alto índice de sospecha, el médico debe tener la capacidad resolutiva y el conocimiento necesarios para el manejo y hacer uso racional de los recursos diagnósticos. Es necesario adoptar medidas terapéuticas que impacten positivamente en el pronóstico y que reduzcan la morbimortalidad.
Oncological emergencies are common complications resulting from the natural evolution of the tumor or its management; however, some of them may be subtle or even overlooked, which contributes to greater morbidity and mortality. Our aim was to gather updated information on the main oncological complications. A narrative literatura review was performed by searching for original articles, systematic reviews and narratives, in databases such as Scopus, SciELO, PubMed, ScienceDirect and in the Google Scholar search engine. 63 references were selected that addressed relevant information about the oncological emergencies raised for the development of the article. According to their origin, complications can be classified into infectious (febrile neutropenia), metabolic (tumor lysis syndrome and malignant hypercalcemia) and obstructive (superior vena cava syndrome, intestinal obstruction, spinal cord compression and cardiac tamponade). Facing these complications requires a high level of suspicion; the physician must be able to resolve each complication and have the necessary knowledge to approach each case, with a rational use of diagnostic resources. It is also necessary to adopt therapeutic measures that positively impact patients. patient prognosis, decreasing morbidity and death.

Superior vena cava syndrome (SVCS) is an entity that has become more frequent due to the increasing use of indwelling central venous catheters. Surgical management is considered in patients with extensive venous thrombosis and when endovascular therapy is not feasible. The use of superficial femoral vein is an excellent technique for reconstruction of the brachiocephalic vein and superior vena cava (SVC) in cases with benign and malignant etiologies. We describe two cases of SVCS that were managed surgically at our institution with replacement of the SVC and brachiocephalic veins with a superficial femoral vein graft technique.

El paciente oncológico de cuidados paliativos puede presentar una variedad importante de condiciones clínicas que producen sufrimiento y disminución en la calidad de vida; esto se presenta como un reto para el clínico en la identificación y correcto abordaje de los pacientes. El dolor se ha considerado por años como el síntoma cardinal a tratar en el paciente oncológico, donde se deben considerar sus condicionantes fisiopatológicos, la farmacología de las intervenciones, los posibles efectos secundarios y los condicionantes familiares, sociales y personales del dolor, pero a pesar de su relevancia, no es el único síntoma, estando acompañado de un abanico de patologías, como las afectaciones gastrointestinales, pulmonares, vasculares, hematológicas y neurológicas, que favorecen la pérdida de capacidad del paciente y, en muchas ocasiones, la muerte. Se realizó una revisión actualizada en bases de datos como EMBASE, PUBMED, SCIELO, además de la revisión de guías de asociaciones internacionales con el objetivo de acercar a todos los médicos, sin distinguir su especialidad o área de trabajo, al abordaje y manejo del paciente oncológico en cuidado paliativo, favoreciendo la sensibilización con estas patologías y la importancia en el curso de vida de los pacientes.
The palliative care cancer patient can present a significant variety of clinical conditions that produce suffering and a decrease in the quality of life. This is a challenge for the clinician in the identification and correct approach of patients. Pain has been considered for years as the cardinal symptom to be treated in cancer patients, where its pathophysiological factors, the pharmacology of the interventions, possible side effects and the family, social and personal conditions of pain must be considered, but despite its relevance is not the onset of symptoms and is accompanied by a range of pathologies such as gastrointestinal, pulmonary, vascular, hematological and neurological affectations that favor the loss of capacity of the patient and in many cases death. An updated review was carried out in databases such as EMBASE, PUBMED, SCIELO in addition to the revision of guides from international associations with the aim of bringing all doctors without distinguishing their specialty or area of work to the approach and management of cancer patients in palliative care favoring awareness of these pathologies and their importance in the life course of patients.

OBJECTIVE: Thoracic central vein (TCV) obstruction (TCVO) in the presence of upper extremity (UE) hemodialysis access can present as superior vena cava syndrome (SVCS) and cause vascular access dysfunction and failure. We report the techniques and results of endorevascularization of TCVO in hemodialysis patients, which allowed for long-term functioning vascular access in the UE. METHODS: From June 2009 to February 2020, 45 hemodialysis patients underwent TCV endorevascularization. The indications for surgery were TCVO or SVCS that threatened the function of a preexisting upper arm access or contraindicated placement of a new upper arm access. Conventional endovascular techniques were used when feasible. Patients with unfavorable anatomy were treated using a transseptal needle to cross difficult intrathoracic stenosis and occlusions or to facilitate an inside-out central venous access technique. The reestablishment of venous outflow was accomplished with angioplasty, stenting, and/or placement of HeRO conduits. Successful revascularization was followed by hemodialysis access revision or a new UE access placement. We recorded the risk factors and procedural outcomes, patency rates, complications, and mortality. RESULTS: The mean age was 53 ± 16.3 years, and 51% were women. The most common risk factors were diabetes mellitus (64.2%) and hypertension (56%). Twenty-five patients (55.5%) had symptoms of SVCS. These symptoms resolved after the TCV procedure in all cases. Crossing of the TCV lesion was successful using a conventional catheter and wire in 26 cases (57.8%) and transseptal needle in 17 cases (37.8%), including 12 using an inside-out central venous access technique. Treatment of the TCV lesion included a HeRO conduit in 20 cases (44.4%), stenting in 17 (37.7%), and transluminal balloon angioplasty alone in 7 (15.5%). Other veins were treated in 33 cases (73.3%). The overall technical success rate was 95.5%. Two intraoperative complications occurred, including one case of severe hypotension and one of fatal cardiac tamponade. Of the 16 patients with preexisting UE access, its function was preserved in all 16 (100%). In 24 of 27 patients (85.7%), new arm access was successfully created after the TCV procedure. The overall clinical success rate was 88.9%. The average follow-up was 663.4 days (median, 507 days; range, 0-2679 days). During follow-up, 26 patients had undergone 90 procedures to maintain access function, 21 had undergone repeat endovascular interventions, and 17 had undergone open procedures. Eight patients (17.8%) had developed infection, five involving HeRO conduits that required excision with loss of access. During the follow-up period, 14 patients (31%) had died of unrelated causes, and 34 patients (75.5%) maintained functional access. CONCLUSIONS: The results of the present study have shown that endorevascularization of TCVO reconstruction is effective in maintaining function or allowing the creation of UE hemodialysis access, with acceptable complication rates.
