Thyroid abnormalities in patients with Hodgkin lymphoma: The importance of close surveillance.

INTRODUCTION: Survival in paediatric patients with Hodgkin lymphoma (HL) has increased over the last decades. However, these patients are at increased risk of developing late thyroid sequelae due to the treatment with irradiation and alkylating agents. METHODS: We conducted an observational and retrospective study in patients with a diagnosis of HL between 2007 and 2022, in a hospital that is a paediatric oncology reference centre, through the review of electronic health records. We collected data on demographic (age, sex), clinical, radiological and histopathological variables, the dosage of alkylating agents and radiotherapy (RT) and on thyroid disorders using Microsoft Excel. The data analysis was conducted with SPSS version 17, using the Fisher exact test for qualitative data, a nonparametric test for quantitative data and Kaplan-Meier curves. RESULTS: Sixty patients received a diagnosis of HL from 2007 to 2022. The median duration of follow-up was 78.5 months. There were 4 detected cases of hypothyroidism, 5 of thyroid nodules and 1 of subclinical hyperthyroidism. Treatment with RT was significantly associated with the development of hypothyroidism (P= .026), thyroid nodules (P= .01) and thyroid disease overall (P= .003). We estimated that the risk of thyroid disease increased 8-fold with each additional Grey received (hazard ratio, 1.081; 95% CI, 1.014-1.152; P= .017). CONCLUSION: Hodgkin lymphoma patients treated with RT are at increased risk of late thyroid disorders, mainly hypothyroidism and malignancy. This risk is greater the higher the RT dosage and the longer the follow-up. We did not find evidence of an association between the use of alkylating agents and an increase in the risk of thyroid disease.

Experience With Bexarotene to Treat Cutaneous T-Cell Lymphomas: A Study of the Spanish Working Group of Cutaneous Lymphomas. / [[Artículo traducido]]Experiencia con bexaroteno en linfoma cutáneo de células T: un estudio del Grupo Español de Linfomas Cutáneos (GELC).

BACKGROUND AND OBJECTIVES: Bexarotene has been approved to treat advanced stage cutaneous T-cell lymphomas (CTCL) since 1999. However, very few data have been published on its long-term safety and efficacy profile. The aim of this study is to determine the tolerability to bexarotene and outcomes by collecting the 2nd largest case series to date on its long-term use vs CTCL. MATERIAL AND METHOD: This was a multicenter retrospective review of 216 patients with mycosis fungoides (174), or Sézary syndrome (42) on a 10-year course of bexarotene alone or in combinationwith other therapies at 19 tertiary referral teaching hospitals. RESULTS: A total of 133 men (62%) and 83 women (38%) were included, with a mean age of 63.5 year (27-95). A total of 45% were on bexarotene monotherapy for the entire study period, 22% started on bexarotene but eventually received an additional therapy, 13% were on another treatment but eventually received bexarotene while the remaining 20% received a combination therapy since the beginning. The median course of treatment was 20.78 months (1-114); and the overall response rate, 70.3%. Complete and partial response rates were achieved in 26% and 45% of the patients, respectively. Treatment was well tolerated, being the most common toxicities hypertriglyceridemia (79%), hypercholesterolemia (71%), and hypothyroidism (52%). No treatment-related grade 5 adverse events were reported. CONCLUSIONS: Our study confirms bexarotene is a safe and effective therapy for the long-term treatment of CTCL.

Evolução da Captação Miocárdica de 18F-FDG em Paciente com Diagnóstico de Cardiotoxicidade / Progression of Myocardial 18F-FDG Uptake in a Patient with Cardiotoxicity

Resumo O objetivo deste relato é mostrar a evolução da cardiotoxicidade (CTX) por quimioterápicos em paciente com linfoma por exames de imagens, destacando a importância da captação miocárdica de flúor-18 fluordeoxiglicose (18F-FDG) pela tomografia por emissão de pósitrons, acoplada à tomografia computadorizada (PET/CT). Feminino, 43 anos, com linfoma uterino, submetida a histerectomia, três esquemas de quimioterapia (QT), sucessivamente, e radioterapia. Apresentou episódios de insuficiência cardíaca aguda dois anos após QT. Ecocardiograma mostrou redução da fração de ejeção do ventrículo esquerdo (FEVE). Análise retrospectiva do 18F-FDG PET/CT observou elevação da captação miocárdica em todos os exames durante o seguimento oncológico. Apesar da remissão oncológica, a paciente desenvolveu IC com FEVE reduzida. Durante a QT, ocorreu aumento difuso e significativo da captação miocárdica de 18F-FDG, que precedeu a queda do desempenho cardíaco, e pareceu refletir alterações metabólicas nos cardiomiócitos relacionadas à CTX. A análise da captação miocárdica de 18F-FDG modificaria o desfecho cardiológico da paciente? Esse questionamento é relevante, visto que outros pacientes podem se beneficiar desse método como marcador precoce de CTX. Os exames de imagem são imprescindíveis no acompanhamento de pacientes com risco de CTX. O ecocardiograma permanece como principal auxílio diagnóstico, porém o 18F-FDG PET/CT pode estar surgindo como uma poderosa ferramenta para um diagnóstico mais precoce dessa condição clínica.

Abstract The objective of this case report was to present the progression of chemotherapy-induced cardiotoxicity in a patient with lymphoma, highlighting the importance of myocardial fluor-18-fluorodeoxyglucose (18F-FDG) uptake by positron emission tomography coupled with computed tomography (PET/CT). 43-year-old female patient with uterine lymphoma, who underwent hysterectomy followed by three chemotherapy regimens and radiotherapy. The patient had episodes of acute heart failure two years after chemotherapy. Echocardiogram revealed a reduction in left ventricular ejection fraction (LVEF). A retrospective analysis of 18F-FDG PET/CT showed an increase in myocardial uptake in all tests performed during oncologic treatment. Despite disease remission, the patient developed heart failure with reduced LVEF. During chemotherapy, there was a diffuse, significant increase in myocardial 18F-FDG uptake, which preceded the decrease in myocardial performance and seemed to reflect metabolic changes in cardiomyocytes, related to cardiotoxicity. Would an analysis of myocardial 18F-FDG uptake yield a different cardiac outcome in this patient? This question is relevant, considering that other patients may benefit from the use of PET as an early marker of cardiotoxicity. Imaging tests are essential in the follow-up of patients at risk of cardiotoxicity. Although echocardiography remains the main imaging test in the diagnosis of cardiotoxicity, 18F-FDG PET/CT may be a powerful tool for the early diagnosis of this condition.

Linfoma vitreorretiniano: un reto diagnóstico / Vitreoretinal lymphoma: A diagnostic challenge

Se presenta el caso de un varón de 66años remitido por uveítis posterior con edema macular quístico recurrente en relación con posible enfermedad de Lyme previamente tratada. Debido a la recurrencia del edema macular pese al tratamiento corticoideo sistémico y local con dexametasona intravítrea, se instaura tratamiento biológico con adalimumab. Durante el seguimiento el paciente desarrolla lesiones subretinianas bilaterales compatibles con linfoma vitreorretiniano, por lo que se realiza vitrectomía, confirmando el diagnóstico de linfoma de célulaB grande.Se inicia tratamiento con quimioterapia sistémica con BRAM (carmustina, metotrexato, ara-C y rituximab), con buena respuesta. Dos años después, el paciente permanece sin recurrencias a nivel ocular ni sistémico.El linfoma vitreorretiniano es un tipo poco frecuente de linfoma primario del sistema nervioso central. El diagnóstico se ve frecuentemente retrasado debido a la inespecificidad de su sintomatología, que simula una uveítis posterior crónica; de ahí la importancia de la sospecha diagnóstica. (AU)

A 66-year-old man with posterior uveitis and recurrent cystic macular edema related to possible previously treated Lyme disease is presented. Due to the recurrence of macular edema despite systemic and local corticosteroid treatment with intravitreal dexamethasone, biological treatment with adalimumab was established. During follow-up, the patient developed bilateral subretinal lesions compatible with vitreoretinal lymphoma, so vitrectomy was performed, confirming the diagnosis of large B-cell lymphoma.Treatment with systemic chemotherapy with BRAM (carmustine, metotrexate, ara C, and rituximab) was started with a good answer. Two years later, the patient remains without ocular or systemic recurrences.Vitreoretinal lymphoma is a rare type of primary central nervous system lymphoma. The diagnosis is frequently delayed due to the nonspecific symptoms, which mimic chronic posterior uveitis, hence the importance with a diagnostic suspicion. (AU)

Linfoma difuso de célulasB grandes primario de cérvix. A propósito de un caso / Primary diffuse large Bcell lymphoma of the cervix: Clinical case

Introducción: La afectación primaria del tracto genital femenino por linfoma no Hodgkin es muy poco frecuente, por lo que no existe un consenso sobre el tratamiento, y por ello presentamos este caso clínico y el tratamiento realizado, así como el pronóstico de nuestra paciente. Hallazgos clínicos: La paciente presentada es una mujer de 72años que consulta por hemorragia vaginal. Diagnóstico Se diagnostica de linfoma no Hodgkin extranodal primario de cérvix de inmunofenotipoB de alto grado citológico y elevado índice proliferativo. Intervenciones terapéuticas y resultados: El tratamiento de elección fue únicamente quimioterápico. Esta paciente ha presentado una supervivencia libre de enfermedad de 5años. Actualmente se encuentra en seguimiento mediante la realización de controles analíticos anuales. Conclusión: Los síntomas de este tipo de tumor son altamente inespecíficos y la citología es frecuentemente negativa, por lo que es necesario recurrir a la biopsia. La inmunohistoquímica resulta fundamental tanto para el diagnóstico como para el pronóstico. Existen múltiples técnicas de imagen empleadas tanto para estudio de extensión como para seguimiento, destacando el papel del FDG-PET. Actualmente parece que el tratamiento más recomendable es la pauta quimioterápica R-CHOP seguida de radioterapia. El pronóstico en general es bueno, con hasta un 80% de supervivencia a los 5años.(AU)

Introduction: Primary involvement of the female genital tract by non-Hodgkin lymphoma is very rare, so there is no consensus on treatment, and for this reason we present this clinical case and the treatment performed, as well as the prognosis of our patient. Clinical findings: The patient presented is a 72-year-old woman who consulted for vaginal bleeding. Diagnosis: Primary extranodal non-Hodgkin lymphoma of the cervix with immunophenotypeB of high cytological grade and high proliferative index was diagnosed. Therapeutic interventions and results: The treatment of choice was chemotherapy only. This patient has presented a disease-free survival of 5years. It is currently being monitored by carrying out annual analytical controls. Conclusion: The symptoms of this type of tumor are highly non-specific, as well as cytology is frequently negative, which is why it is necessary to resort to biopsy. Immunohistochemistry is essential for both diagnosis and prognosis. There are multiple imaging techniques used for both extension study and follow-up, highlighting the role of FDG-PET. It currently seems that the most recommendable treatment is the R-CHOP chemotherapy regimen followed by radiotherapy.The prognosis is generally good, with up to 80% survival at 5years.(AU)

Linfadenopatías generalizadas como manifestación inicial de lupus eritematoso sistémico: a propósito de un caso clínico

La presencia de linfadenopatías generalizadas se ha asociado de forma usual con lupus eritematoso sistémico (LES), sin embargo, no es usual encontrar este hallazgo como manifestación inicial de la enfermedad. Existen múltiples diagnósticos diferenciales que incluyen la linfadenitis necrotizante histiocítica de Kikuchi, la enfermedad de Castleman, infecciones y el linfoma cuando se presenta este hallazgo como síntoma inicial de LES. Presentamos el caso de un hombre de 56 años que se presentó con 2 meses de linfadenopatía generalizada sin datos al examen o antecedentes que sugirieran diagnóstico de LES; se sospechó inicialmente linfoma o enfermedad infecciosa y se realizó un estudio exhaustivo incluido biopsia de ganglio cervical. La investigación de laboratorio finalmente reveló leucopenia, proteinuria significativa, ANA y anti-dsDNA positivos e hipocomplementemia, lo que confirma el diagnóstico de enfermedad autoinmune tipo LES. Este caso ilustra la importancia de reconocer esta forma de presentación inusual, dado que se trata de una enfermedad potencialmente fatal.

The presence of generalized lymphadenopathy has usually been associated with systemic lupus erythematosus (SLE), however, it is not usual to find this finding as an initial manifestation of the disease. There are multiple differential diagnoses that include Kikuchi histiocytic necrotizing lymphadenitis, Castleman disease, infections and lymphoma when this finding is presented as an initial symptom of SLE. We present the case of a 56-year-old man who presented with 2 months of generalized lymphadenopathy without examination findings or history suggesting a diagnosis of SLE; Lymphoma or infectious disease was initially suspected and an exhaustive study was performed, including cervical lymph node biopsy. Laboratory investigation finally revealed leukopenia, significant proteinuria, positive ANA, positive anti-dsDNA, and hypocomplementemia, confirming the diagnosis of SLE-type autoimmune disease. This case illustrates the importance of recognizing this unusual presentation, given that it is a potentially fatal disease.

Síndrome de dificultad respiratoria aguda por Mycobacterium tuberculosis de rápido crecimiento en una mujer con virus linfotrópico T humano tipo I-II / Acute respiratory distress syndrome due to rapidly growing Mycobacterium tuberculosis in a woman with human T-lymphotropic virus type I-II

La tuberculosis es una infección de distribución mundial con una alta morbimortalidad en países subdesarrollados. Presentamos el caso de una mujer de 55 años con cuadro de dos meses de adenomegalias cervicales, pérdida de peso y fiebre con posterior disnea de esfuerzo progresiva. Ingresó por urgencias en falla ventilatoria y hallazgos radiológicos compatibles con síndrome de dificultad respiratoria aguda (SDRA) requiriendo ventilación mecánica invasiva. Se demostró infección por M. tuberculosis por PCR en tiempo real GeneXpert MTB/RIF Ultra y en cultivo de medio líquido de esputo, con crecimiento en tiempo menor a tres días. La biopsia de las adenomegalias confirmó linfoma de células T periférico asociado a infección por virus linfotrópico T humano tipo I-II, presentando una evolución tórpida a pesar del esquema quimioterapéutico.

Tuberculosis is a globally distributed infection with high morbidity and mortality in underdeveloped countries. We present the case of a 55-year-old woman with a 2-month history of cervical lymph nodes, weight loss, and fever with subsequent progressive exertional dyspnea. She was admitted to the emergency department with ventilatory failure and radiological findings compatible with acute respiratory distress syndrome (ARDS) requiring invasive mechanical ventilation. M. tuberculosis infection was proved by a real-time PCR GeneXpert MTB/RIF Ultra and in culture of sputum liquid medium, with growth in less than 3 days. The biopsy of the lymph nodes revealed peripheral T-cell lymphoma associated with infection by human T-lymphotropic virus type I-II, presenting a torpid evolution despite the chemotherapy regimen.

Vitreoretinal lymphoma: a diagnostic challenge.

A 66-year-old man with posterior uveitis and recurrent cystic macular edema related to possible previously treated Lyme disease is presented. Due to the recurrence of macular edema despite systemic and local corticosteroid treatment with intravitreal dexamethasone, biological treatment with Adalimumab was established. During follow-up, the patient developed bilateral subretinal lesions compatible with Vitreoretinal Lymphoma (VRL), so vitrectomy was performed, confirming the diagnosis of large B-cell lymphoma. Treatment with systemic chemotherapy with BRAM-Carmustine, Metrotexate, Ara C, and Rituximab was started with a good answer. Two years later, the patient remains without ocular or systemic recurrences. Vitreoretinal Lymphoma is a rare type of primary central nervous system lymphoma. The diagnosis is frequently delayed due to the nonspecific symptoms, which mimic chronic posterior uveitis, hence the importance with a diagnostic suspicion.

Metodología: programa de diez sesiones de intervención que se divide en tres fases: conceptualización, que incluye el modelo teórico de estrés y de intolerancia a la incertidumbre; adquisición de estrategias y ensayo que incorpora técnicas de desactivación y cognitivas, planificación de actividades y entrenamiento en habilidades de comunicación; consolidación. Resultados: se evidencia una reducción del malestar emocional, de la sintomatología de ansiedad y bajo estado de ánimo, así como de los niveles de fatiga. Respecto a las estrategias de afrontamiento, tras la intervención psicológica se mantiene el estilo de preocupación ansiosa, aunque se observa un mejor uso de recursos asociados al afrontamiento de espíritu de lucha. Conclusión: la aplicación sistemática de programas para el manejo del estrés puede suponer una estrategia útil y efectiva para la mejora de la salud mental de los pacientes que van a someterse a tratamiento de células CART (AU)

Objective: A case report is presented of a patient with diffuse B lymphoma who is a candidate for CART cell therapy using a stress inoculation program due to the characteristics of the disease and medical treatment and the associated uncertainty. Methodology: psychological program intervention with 10 sessions, divided into three phases: Conceptualization, including the theoretical model of stress and uncertainty intolerance; strategy acquisition and rehearsal, incorporating deactivation and cognitive techniques, activity planning and communication skills training; consolidation. Results: there was a reduction in emotional distress, anxiety symptoms and mood, as well as fatigue levels. In terms of coping strategies, after the psychological intervention, the anxious worrying style is maintained, although a better use of the resources associated with coping with a fighting spirit is observed. Conclusion: Systematic application of stress management programs can be a useful and effective strategy for improving the mental health of patients undergoing CART cell treatment (AU)

Exoftalmos y dolor ocular como presentación clínica de linfoma de Hodgkin con afectación intracraneal al diagnóstico / Exophthalmos and ocular pain as clinical debut of intracranial Hodgkin's lymphoma at diagnosis

La afectación intracraneal del linfoma de Hodgkin (LH) es extremadamente rara, especialmente como forma de presentación de la enfermedad. Muestra un patrón radiológico inespecífico, pudiendo ser confundido con otras entidades de mayor frecuencia y pronóstico radicalmente distinto. Anatomopatológicamente se caracteriza por la presencia de células grandes binucleadas (células de Reed-Sternberg) eIntracranial involvement in Hodgkin's lymphoma (HL) is extremely unusual, especially at the time of diagnosis. Because of its non-specific radiological behaviour, it can be confused with more common entities with a radically different prognosis. Pathologically, large and bi-nucleated cells, called Reed-Sternberg cells, embedded in an inflammatory network.

In this report we describe the clinical case of a patient, with no medical history, with left ocular pain and exophthalmos as presentation of intracranial HL at diagnosis and review the most current literature. Intracranial involvement is often associated with extracranial disease. Therefore, a systemic study including body computed tomography, bone marrow biopsy and ophthalmological evaluation is necessary. Intracranial lesions respond favourably to treatment and the prognosis depends on the extracranial involvement. To date, there is no standardised management scheme for these patients. For us, the primary role of surgery in this context is to perform a biopsy to confirm the histological diagnosis (AU)mbebidas en un entramado inflamatorio. Presentamos el caso de una paciente con dolor ocular y exoftalmos izquierdo como presentación clínica de afectación intracraneal por LH al diagnóstico de su enfermedad y revisamos la literatura más reciente al respecto. En pacientes con LH intracraneal es necesario realizar un estudio de extensión con tomografía computarizada corporal, biopsia de médula ósea y examen oftalmológico. Se asocia con gran frecuencia a enfermedad extracraneal, que marca el pronóstico. La lesión intracraneal presenta buena respuesta al tratamiento, que no sigue un esquema estandarizado. El papel de la cirugía es la realización de una biopsia para confirmar el diagnóstico (AU)

Manejo conservador con radioterapia e inmunoquimioterapia en el linfoma difuso de células B grandes primario de cuello uterino: Diagnóstico y tratamiento de una entidad rara / Conservative management with radiotherapy and immunochemotherapy in primary diffuse large B-cell lymphoma of the cervix: Diagnosis and treatment of a rare entity

Introducción: El linfoma maligno primario de cuello uterino es una enfermedad muy rara, que representa solo el 0,008% de todos los tumores de cérvix y el 2% de todos los linfomas extraganglionares femeninos.Principales síntomas o hallazgos clínicos: Se presenta el caso de una mujer de 66 años, de los Andes peruanos, con tiempo de enfermedad de 4 meses caracterizado por ginecorragia, con evidencia de cérvix tumoral de 5cm. Se realizó inmunohistoquímica a la biopsia de cérvix para diferencia linfoma del carcinoma epidermoide.Diagnóstico principal: Linfoma difuso de células B grandes primario de cuello uterino con estadificación Ann Arbor IE IPI de bajo riesgo.Intervenciones terapéuticas y resultados: Fue manejada con inmunoquimioterapia (rituximab, ciclofosfamida, adriamicina, vincristina y prednisona), seguida de radioterapia externa consolidativa a dosis de 3.000 cGy en 15 sesiones con técnica especial IMRT. El control de la enfermedad resultó satisfactorio y no presentó complicaciones por la irradiación.Conclusión: El linfoma difuso de células B grandes primario de cuello uterino es muy raro, por lo que, en un caso de lesión primaria del estroma del cérvix, debe tenerse en cuenta la sospecha de linfoma.(AU)

Introduction: Primary malignant cervical lymphoma is a very rare disease, which represents only 0.008% of all cervical tumors and 2% of all female extranodal lymphomas. Main symptoms and/or clinical findings: The case of a 66-year-old woman from the Peruvian Andes is presented, with a disease period of 4 months characterized by gynaecorrhagia, with evidence of a 5cm tumor cervix. Immunohistochemistry was performed on the biopsy of cervix to differentiate lymphoma from squamous cell carcinoma. Primary diagnosis: Primary diffuse large B-cell lymphoma of the cervix with Ann Arbor IE IPI low-risk staging. Therapeutic interventions and results: She being managed with immunochemotherapy (rituximab, cyclophosphamide, adriamycin, vincristine and prednisone), followed by consolidative external radiotherapy at a dose of 3,000cGy in 15 sessions with a special IMRT technique. Resulting in satisfactory disease control and no complications from irradiation.Conclusion: Primary diffuse large B-cell lymphoma of the cervix is very rare, therefore, in a case of primary stromal lesion of the cervix, suspicion of lymphoma should be taken into account.(AU)

Survival of patients living with HIV and cancer in Cali, Colombia

Background: People living with HIV have an increased risk of cancer compared to the general population. However, with the increase in life expectancy and advances in antiretroviral therapy, the survival of patients with cancer and HIV has changed. Objective: To determine the survival of patients living with HIV and cancer in Cali, Colombia Methods: A retrospective cohort study was conducted at the Fundación Valle del Lili, Cali, Colombia. Data from the HIV database was crossed with data from the hospital and population-based cancer registries between 2011-2019. Patients <18 years, limited available clinical information on the diagnosis and treatment of HIV and cancer, and non-oncological tumor diagnosis were excluded. Results: A total of 173 patients were included. The frequencies of AIDS-defining neoplasms were: Non-Hodgkin lymphoma (42.8%), Kaposi sarcoma (27.8%), and cervical cancer (4.6%). Overall survival was 76.4% (95% CI 68.9-82.3) at five years. Poorer survival was found in patients with AIDS-defining infections (56.9% vs. 77.8%, p=0.027) and non-AIDS-defining infections (57.8% vs. 84.2%, p=0.013), while there was better survival in patients who received antiretroviral therapy (65.9% vs. 17.9%, p=0.021) and oncological treatment (66.7% vs. 35.4%, p<0.001). The presence of non-AIDS-defining infections increases the risk of dying (HR = 2.39, 95% CI 1.05-5.46, p=0.038), while oncological treatment decreases it (HR = 0.33, 95% CI 0.14-0.80, p=0.014). Conclusions: In people living with HIV, Non-Hodgkin lymphoma and Kaposi sarcoma are the most common neoplasms. Factors such as AIDS-associated and non-AIDS-associated infections have been identified as determinants of survival. Cancer treatment seems to improve survival.

Antecedentes: Las personas que viven con VIH tienen un riesgo mayor de cáncer en comparación con la población general. Sin embargo, con el aumento de la esperanza de vida y los avances en la terapia antirretroviral, la supervivencia de los pacientes con cáncer y VIH ha cambiado. Objetivo: Determinar la supervivencia de los pacientes que viven con VIH y cáncer en Cali, Colombia. Métodos: Se realizó un estudio de cohorte retrospectivo en la Fundación Valle del Lili, Cali, Colombia. Los datos de la base de datos de VIH se cruzaron con los datos de los registros de cáncer de base hospitalaria y poblacional entre 2011-2019. Se excluyeron los pacientes <18 años, con información clínica limitada disponible sobre el diagnóstico y tratamiento del VIH y el cáncer y los casos con diagnóstico de tumor no oncológico. Resultados: Se incluyeron un total de 173 pacientes. Las frecuencias de neoplasias definitorias de SIDA fueron: linfoma no Hodgkin (42.8%), sarcoma de Kaposi (27.8%) y cáncer cervical (4.6%). La supervivencia global fue del 76.4% (IC 95% 68.9-82.3) a los cinco años. Se encontró una peor supervivencia en pacientes con infecciones definitorias de SIDA (56.9% vs. 77.8%, p=0.027) e infecciones no definitorias de SIDA (57.8% vs. 84.2%, p=0.013), mientras que hubo una mejor supervivencia en pacientes que recibieron terapia antirretroviral (65.9% vs. 17.9%, p=0.021) y tratamiento oncológico (66.7% vs. 35.4%, p<0.001). La presencia de infecciones no definitorias de SIDA aumentó el riesgo de morir (HR = 2.39, IC 95% 1.05-5.46, p=0.038), mientras que el tratamiento oncológico lo disminuyó (HR = 0.33, IC 95% 0.14-0.80, p=0.014). Conclusiones: En las personas que viven con VIH, el linfoma no Hodgkin y el sarcoma de Kaposi son las neoplasias más comunes. Se han identificado factores como las infecciones asociadas al SIDA y las infecciones no asociadas al SIDA como determinantes de la supervivencia. El tratamiento del cáncer parece mejorar la supervivencia.

COVID-19 y leucemia/linfoma T del adulto, sinergia mortal / COVID-19 and adult T cell leukemia-lymphoma: a deadly synergy

La leucemia/linfoma T del adulto es una neoplasia maligna de mal pronóstico frecuente en población anciana. Se presenta el caso de una mujer de 44 años de edad, de Ayacucho, diagnosticada con el subtipo linfomatoso de esta enfermedad e infección por virus linfotrópico T humano-I; mostró síndrome oclusivo de vena cava superior con tratamiento de quimioterapia sistémica bajo régimen de dosis ajustada con rituximab más etoposido, prednisona, vincristina, ciclofosfamida y doxorubicina. Posteriormente ingresó en emergencia por presentar dificultad respiratoria, tos seca, disminución de la conciencia, hipercalcemia, tomografía de tórax con patrón heterogéneo consolidativo en ambos pulmones y PCR en hisopado nasofaríngeo positivo a COVID-19. Recibió tratamiento de hidroxicloroquina, azitromicina, corticoides e ivermectina con pobre respuesta, rápido deterioro y fallece días después. La leucemia/linfoma T del adulto a edad temprana es rara y está relacionada con infecciones crónicas como strongyloides o tuberculosis, susceptible ante el padecimiento de COVID-19.

Adult T cell leukemia-lymphoma is a common malignancy with a poor prognosis in the elderly population. We present a 44-year-old woman from Ayacucho who was diagnosed with a lymphoma subtype of this disease and a human T-lymphotropic virus-I infection; she showed superior vena cava occlusive syndrome with systemic chemotherapy treatment under an adjusted-dose regimen with rituximab plus etoposide, prednisone, vincristine, cyclophosphamide and doxorubicin. Subsequently, she was admitted to the emergency service due to respiratory distress, dry cough, decreased consciousness, hipercalcemia, chest tomography with a heterogeneous consolidation pattern in both lungs and positive RT-PCR nasopharyngeal swab test for COVID-19. She received treatment with hydroxychloroquine, azithromycin, corticosteroids and ivermectin with a poor response, rapid deterioration and died later. Adult T cell leukemia-lymphoma at an early age is rare and is related to chronic infections such as strongyloides or tuberculosis, susceptible to COVID-19.

Exophthalmos and ocular pain as clinical debut of intracranial Hodgkin's lymphoma at diagnosis.

Intracranial involvement in Hodgkin's Lymphoma (HL) is extremely unusual, especially at the time of diagnosis. Because of its non-specific radiological behaviour, it can be confused with more common entities with a radically different prognosis. Pathologically, large and bi-nucleated cells, called Reed-Sternberg cells, embedded in an inflammatory network. In this report we describe the clinical case of a patient, with no medical history, with left ocular pain and exophthalmos as presetation of intracranial HL at diagnosis and review the most current literature. Intracranial involvement is often associated with extracranial disease. Therefore, a systemic study including body computed tomography, bone marrow biopsy and ophthalmological evaluation is necessary. Intracranial lesions respond favourably to treatment and the prognosis depends on the extracranial involvement. To date, there is no standardised management scheme for these patients. For us, the primary role of surgery in this context is to perform a biopsy to confirm the histological diagnosis.

Linfoma no Hodgkin difuso de células B grande como linfoma primario de ovario. Presentación de caso / Diffuse large B-cell non-Hodgkin's lymphoma as primary ovarian lymphoma. Case presentation

Fundamento: Los linfomas primarios de ovario son poco frecuentes; el 1 % de estos se presenta en ovario y el 1.5 % de los tumores malignos de ovario son linfomas. Los tipos histológicos más frecuentes es el linfoma no Hodgkin difuso de células B grande y el BurKitt; el tratamiento consiste en cirugía combinada con quimioterapia. Objetivo: Reportar un caso de un linfoma no Hodgkin difuso de células B grande primario de ovario. Presentación de caso: Se presentó el caso de una paciente de 39 años de edad, con antecedentes patológicos personales de salud; la cual fue al cuerpo de guardia de ginecología por presentar dolor abdominal difuso que no se aliviaba con analgésicos. En la exploración física presentaba dolor a la palpación superficial y profunda en hipocondrio y fosa ilíaca derecha con masa tumoral palpable. Ecografía hacia proyección anexial derecha se observó una imagen de baja ecogenicidad y en la laparoscopia de urgencia se concluyó como una formación de aspecto tumoral que parecía corresponderse con ovario derecho. Se le realizó una histerectomía con doble anexectomía. El diagnóstico anatomopatológico fue un linfoma no Hodgkin primario de ovario. Conclusiones: La paciente del caso presentado tuvo una clínica oligosintomática y la confirmación de la enfermedad fue a partir de una muestra quirúrgica, lo que expresa que el diagnóstico del linfoma no Hodgkin de células B es difícil y aunque es poco frecuente siempre se debe tener en cuenta en el diagnóstico diferencial de las tumoraciones unilaterales de ovario.

Background: Primary ovarian lymphomas are uncommon, 1% of these malignancies occur in the ovary, and 1.5% of all ovarian malignancies are lymphomas. The most common histologic types are diffuse large B-cell non-Hodgkin's lymphoma and BurKitt's lymphoma; treatment consists of surgery combined with chemotherapy. Objective: To report a case of primary ovarian diffuse large B-cell non-Hodgkin lymphoma. Case presentation: A 39-year-old female case is presented, with a personal pathological history; she went to the gynecology emergency service because she presented diffuse abdominal pain that was not relieved by analgesics. Physical examination revealed superficial and deep pain on palpation in the hypochondrium and right illiac fossa with a palpable tumor mass. Right adnexal ultrasound showed an image of low echogenicity and at the emergency laparoscopy, it was diagnosed as a tumor-like formation that appeared to correspond to the right ovary. She underwent a hysterectomy with double adnexectomy. The anatomopathologic diagnosis was primary ovarian non-Hodgkin's lymphoma. Conclusions: The patient in the presented case had an oligosymptomatic clinical presentation. Confirmation of the disease was obtained from a surgical sample, which means that B-cell non-Hodgkin's lymphoma is difficult to diagnose and although it is uncommon, it should always be considered in the differential diagnosis of unilateral ovarian tumors.

Linfocitosis monoclonal de células B en familiares de pacientes colombianos con síndromes linfoproliferativos crónicos B

Introducción. La linfocitosis monoclonal de células B, generalmente, precede la leucemia linfocítica crónica y afecta alrededor del 12 % de la población adulta sana. Esta frecuencia se incrementa en familiares de pacientes con síndromes linfoproliferativos crónicos de células B. Objetivo. Determinar la frecuencia de linfocitosis monoclonal B en familiares de pacientes con síndromes linfoproliferativos crónicos B, sus características inmunofenotípicas y citogenéticas, posible relación con agentes infecciosos, y seguimiento a corto plazo de población colombiana. Materiales y métodos. Se estudiaron 50 adultos sanos con antecedentes familiares de síndromes linfoproliferativos crónicos de célula B, empleando citometría de flujo multiparamétrica, pruebas citogenéticas y serológicas, encuesta de hábitos de vida y seguimiento a dos años. Resultados. La frecuencia encontrada de linfocitosis monoclonal B fue del 8 %, con predominio del sexo femenino y edad avanzada, incrementándose al 12,5 % en individuos con antecedentes familiares de leucemia linfocítica crónica. Tres de cuatro individuos presentaron inmunofenotipo de tipo leucemia linfocítica crónica, todas con bajo recuento. A su vez, en estos individuos se observa de manera significativa un mayor número de células/ µl en subpoblaciones linfocitarias T, junto con mayor predisposición a la enfermedad. Las poblaciones clonales descritas aumentan a lo largo del tiempo de manera no significativa. Conclusiones. La frecuencia y comportamiento de la linfocitosis monoclonal de célula B en pacientes con antecedentes familiares de síndromes linfoproliferativos crónicos B es similar a lo encontrado en estudios relacionados, lo que sugiere que no existe afectación de genes de mayor relevancia que puedan desencadenar una proliferación clonal descontrolada, pero que generan desregulación inmunológica que podría indicar un mayor riesgo de infección grave en estos individuos.

Introduction. Monoclonal B-cell lymphocytosis generally precedes chronic lymphocytic leukemia, affecting about 12% of the healthy adult population. This frequency increases in relatives of patients with chronic B-cell lymphoproliferative disorders. Objective. To determine the frequency of monoclonal B-cell lymphocytosis in relatives of patients with chronic B-cell lymphoproliferative disorders, their immunophenotypic/ cytogenetic characteristics, a possible relationship with infectious agents, and short-term follow-up in the Colombian population. Materials and methods. Fifty healthy adults with a family history of chronic B-cell lymphoproliferative disorders were studied using multiparametric flow cytometry, cytogenetic/serological testing, lifestyle survey, and 2-year follow-up. Results. The frequency of monoclonal B-cell lymphocytosis found was 8%, with a predominance of female gender and advanced age, increasing to 12.5% for individuals with a family history of chronic lymphocytic leukemia. Three out of four individuals presented chronic lymphocytic leukemia-type immunophenotype, all with low counts. In turn, a significantly higher number of cells/µΙ is observed in these individuals in T lymphocyte subpopulations, together with a greater predisposition to the disease. The described clonal populations increase over time in a non-significant manner. Conclusions. The frequency and behavior of monoclonal B-cell lymphocytosis in patients with family history of chronic B-cell lymphoproliferative disorders are like those found in related studies, which suggests that there is no involvement of more relevant genes that can trigger uncontrolled clonal proliferation, but that generates immunological deregulation that could justify a greater risk of serious infection in these individuals.

Geotricosis: fungemia en paciente con leucemia linfoblástica aguda / Geotrichosis: fungemia in a patient with acute lymphoblastic leukemia

La fungemia por Geotrichum spp. es poco frecuente y altamente letal. En el Instituto Nacional de Cancerología de Bogotá solo se han reportado dos casos: uno entre el 2001 y el 2007, y el otro entre el 2012 y el 2018. Este tipo de infección es más común en pacientes con algún grado de compromiso del sistema inmunitario, por lo que puede presentarse en pacientes con neoplasias hematológicas malignas. Se presenta el caso de un hombre de 27 años con recaída de leucemia linfoblástica aguda, que ingresó con poliartralgias de cinco días de duración. También cursaba con neutropenia febril, celulitis sin abscesos y bacteriemia por Staphylococcus aureus resistente a la meticilina para lo cual recibió terapia con oxacilina y cefepime. Sin embargo, persistía la neutropenia febril por lo que se sospechó una infección fúngica invasora. Se tomó un nuevo set de hemocultivos y se inició tratamiento antifúngico. En los hemocultivos se identificaron artroconidias y mediante espectrometría de masas por láser de matriz asistida de ionización-desorción se confirmó la presencia de Geotrichum spp. Se ajustó el tratamiento antifúngico con deoxicolato de anfotericina B por 14 días y voriconazol por cuatro semanas. Luego de una estancia prolongada se le dio de alta. Aunque la incidencia de la fungemia por Geotrichum spp. es baja, en pacientes con neoplasias hematológicas malignas debe considerarse en el contexto de una neutropenia febril que es persistente a pesar del tratamiento antimicrobiano de amplio espectro. La identificación de los agentes causantes de fungemias con herramientas de proteómica, como la espectrometría de masas mencionada, permite ajustar el tratamiento dirigido y reducir las complicaciones, la estancia hospitalaria y la mortalidad.

Fungemia caused by Geotrichum spp. is rare and highly lethal. The Instituto Nacional de Cancerología in Bogotá reported just two cases: one in the period 2001-2007 and the other in 2012-2018. This type of infection is more common in any kind of immunocompromised patients, so it can occur in those with hematological malignancies. Here we present the case of a 27-year-old man, diagnosed with acute lymphoblastic leukemia in relapse and admitted with polyarthralgia for five days, febrile neutropenia, non- abscessed cellulitis, and bacteremia due to methicillin-sensitive Staphylococcus aureus. The patient received therapy with oxacillin and cefepime, but the febrile neutropenia persisted. A new set of blood cultures was taken, and antifungal treatment was started because of the suspicion of invasive fungal infection. Arthroconidia were identified in blood cultures and Geotrichum spp. was confirmed using matrix-assisted laser desorption-ionization mass spectrometry. The antifungal treatment was adjusted with amphotericin B deoxycholate for 14 days and voriconazole for four weeks, and after a prolonged stay, the patient was discharged. Although the incidence of fungemia caused by Geotrichum spp. is low, it must be considered in patients with hematological malignancies and persistent febrile neutropenia despite the broadspectrum antimicrobial treatment. The confirmation of fungemia causing agents, with proteomic tools such as the mentioned mass spectrometry, allows treatment adjustment and decreases complications, hospital stay, and mortality.

Síndrome colestásico como forma de presentación de linfoma no Hodgkin. Reporte de un caso pediátrico / Cholestatic syndrome as a presentation of non-Hodgkin lymphoma. A pediatric case report

La ictericia colestásica se debe a la alteración de la secreción de bilirrubina conjugada; es una de las posibles causas la alteración del flujo biliar por obstrucción de la vía biliar extrahepática. El linfoma es la tercera neoplasia más frecuente en pediatría, mientras que los tumores pancreáticos son poco frecuentes y, en su mayoría, lesiones benignas. Las manifestaciones clínicas de los tumores de localización retroperitoneal son poco específicas y suelen ser tardías, por lo que la sospecha clínica debe ser alta. El objetivo del siguiente trabajo es presentar el caso de un niño de 7 años con síndrome colestásico en el que se halló un tumor en la cabeza del páncreas que comprimía la vía biliar extrahepática. El diagnóstico del tumor fue linfoma no Hodgkin (LNH). Se destaca la infrecuencia de este tumor en esta localización en la edad pediátrica

Cholestatic jaundice is due to an alteration in conjugated bilirubin secretion; a possible cause is an altered bile flow resulting from an obstruction of the extrahepatic bile duct. A lymphoma is the third most common neoplasm in pediatrics, while pancreatic tumors are rare and mostly benign. The clinical manifestations of retroperitoneal tumors are not very specific and are usually late, so a high level of clinical suspicion is required. The objective of this study is to describe the case of a 7-year-old boy with cholestatic syndrome with a tumor in the head of the pancreas compressing the extrahepatic bile duct. The tumor diagnosis was non-Hodgkin lymphoma (NHL). It is worth noting that the presence of a tumor in this location in pediatric age is uncommon
