RESUMO

Background: The incidence of Non-Hodgkin Lymphoma (NHL) is increasing, particularly among older patients who tend to have worse outcomes and can be predisposed to increased toxicities and less treatment tolerance. Therefore, a thorough pre-treatment assessment is essential. A comprehensive geriatric assessment (CGA) can be used to evaluate the older patient considering chemotherapy and is the preferred evaluation tool. However, a formal CGA is laborious, complex and time-consuming. Objectives: To characterize older adults with NHL and determine the CGA variables with the greatest association to frailty in order to propose a more simplified assessment. Methods: We performed a cross-sectional study using data collected from CGAs in NHL patients > 65 years admitted to our oncology service, from September 2015 to August 2017. Our evaluation parameters included: polypharmacy, a screening tool of older people's prescriptions (STOPP), the Lawton scale, Barthel index, Katz index, gait speed, a Timed Up and Go (TUG) test, a Mini-Mental state examination (MMSE), the Yesavage and Gijon scales, a Mini-nutritional assessment (MNA), a Geriatric Syndromes assessment, and a Cumulative Illness Rating Scale-Geriatric (CIRS-G). The formal CGA was comprised of nine domains; frailty was defined as an impairment in > 2 domains. Each parameter was individually compared with frailty, and the results were used to build different multivariate models using logistic regression analyses to obtain the variables with the highest frailty association. Results: A total of 253 patients were included. Their median age was 75.4 years (range 65-92), and 62.1% had > 1 impaired domain, with 39.9% considered frail. Bivariate analysis showed strong associations with age > 85 and all the geriatric parameters except for STOPP. Our final multivariate analysis resulted in 5 domains (the use of > 5 medications, a Lawton < 7, TUG > 20, Yesavage > 5, and the presence of at least one geriatric syndrome) being significantly associated with frailty and performing similarly to a CGA. Conclusion: In our population of older NHL patients, an abbreviated evaluation based of only five domains, polypharmacy, TUG, Lawton scale, Yesavage scale and the presence of at least one geriatric syndrome, had similar performance to a formal CGA in determining frailty.

RESUMO

El Linfoma de Células Grandes B difuso asociado al virus Epstein Barr no especificado es una entidad frecuente en Sudamérica, que afecta a pacientes de todas las edades, pero con mayor frecuencia a pacientes seniles. El diagnóstico es a través de la identificación del Epstein Barr virus dentro de la célula tumoral mediante la prueba EBER. El pronóstico es desfavorable a pesar de haber mejorado con la introducción del rituximab. Se cuentan con nuevos scores pronósticos para la identificación de subgrupos de riesgo. El tratamiento continúa siendo el mismo que para los casos de Linfoma de Células Grandes B difuso, virus Epstein Barr negativo. Se esperan nuevas estrategias terapéuticas novedosas frente a esta entidad.


Diffuse Large B-Cell Lymphoma associated with Epstein Barr virus Not otherwise specified is a frequent entity in South America, which affects patients of all ages but more frequently senile patients. Diagnosis is through the identification of the Epstein Barr virus within the tumor cell using the EBER test. The prognosis is unfavorable despite having improved with the introduction of rituximab. There are new prognostic scores for the identification of risk subgroups. The treatment continues to be the same as for cases of Epstein Barr virus-negative diffuse Large B-Cell Lymphoma. New novel therapeutic strategies against this entity are expected.

RESUMO

Introducción: El Linfoma de células grandes B CD5 positivo (LDCGB CD5+) constituye una patología rara y agresiva con pobre respuesta a la quimioinmunoterapia. Objetivo: Describir un caso con diagnóstico de LDCGB CD5+ con recurrencia inusual prostática. Caso clínico: Paciente varón de 61 años con sintomatología de dolor abdominal y síntomas B. Los estudios de imagen mostraron adenopatías mediastinales y retroperitoneales. El informe patológico fue compatible LDCGB CD5+, recibiendo terapia de primera línea con R-CHOP logrando remisión completa, con recaída precoz prostática confirmada por inmunohistoquímica. Posteriormente, inicia terapia de rescate con R-ICE, con pobre respuesta y deterioro del estado funcional. Conclusiones: El LDCGB CD5 + representa una patología infrecuente y agresiva, siendo la recaída en próstata un evento muy inusual, es por ello que los exámenes clínicos exhaustivos y anatomo-patológico son esenciales para un diagnóstico certero. A la fecha, la respuesta a terapias estándar o de mayor intensidad son desalentadoras, por lo que es necesario un mayor número de estudios a futuro(AU)


Introduction: CD5 positive Large B-cell Lymphoma (CD5 + DLBCL) constitutes a rare and aggressive pathology with poor response to chemoimmunotherapy. Objective: To describe a case with a diagnosis of CD5 + DLBCL with an unusual recurrence in the prostate. Clinical case: A 61-year-old male presented abdominal pain and B symptoms. Imaging studies showed mediastinal and retroperitoneal lymphadenopathy. The pathology informed a CD5+ DLBCL diagnosis, receiving first-line R-CHOP treatment and achieving complete remission, with prostatic early relapse confirmed by immunohistochemistry. Therefore, he received R-ICE as rescue treatment with poor response and performance status decline. Conclusions: CD5 + LDCGB represents a rare and aggressive disease, being the prostate relapse a very unusual event, in which the exhaustive clinical and pathological workup is essential for an accurate diagnosis. To date, the response to standard or higher-intensity therapies is disappointing, so more studies are needed in the future(AU)

RESUMO

Introducción: El cáncer gástrico es un problema de salud pública a nivel mundial. Objetivo: Determinar la asociación entre albumina, marcadores inflamatorios y el estadío tumoral de los pacientes con cáncer gástrico en un Hospital Nacional del Perú. Métodos: Estudio de tipo observacional, analítico y retrospectivo correspondiente a los años 2017 y 2018. Se evaluaron las frecuencias y distribucion de las variables de estadío clínico según el AJCC 2018, albúmina como indicador de nutricion e Índice-Neutrófilo Linfocito (INL) como indicador de respuesta inflamatoria-inmunológica. Se consideró 2,44 como el punto de corte para INL elevado. Resultados: Fueron incluidos 96 pacientes. La edad promedio fue de 63,5 años ±12,8, la relacion hombre:mujer fue de 1:1, 80,2% provenían de la region de la costa del Perú; 70,8% tuvieron un estadío clínico avanzado y 85,4% correspondió a tamaño tumoral T3 y T4. El 64% presento grado histologico indeferenciado y un 30,1% mostro evidencia de metastasis. La media de INL fue 2,94 ± 1,7, y de albúmina fue 3,64 g/dl ± 0,6, En el análisis bivariado se encontró una asociación significativa entre el nivel elevado de INL y el estadío clínico avanzado (OR: 4,46 IC 95% 1,65-13,27 p<0,001), y entre los niveles bajos de albúmina sérica con estadio avanzado (OR: 13,02 IC 95% 1,78-5,36 p<0,005). Conclusión:Se encontró un diagnóstico tardío en el 70% de los pacientes. El INL elevado como indicador de respuesta inflamatoria y la albúmina baja como indicador de nutricion son factores predictivos de estadio clínico avanzado en cáncer gástrico.


Introduction: Gastric cancer is a public health problem worldwide. Objective: To determine the association between albumin, inflammatory markers and tumor stage of gastric cancer patients in a National Hospital of Peru. Methods: An observational, analytical and retrospective study corresponding to the 2017 and 2018 years. The frequencies and distribution of the variables were evaluated: clinical stage according to the AJCC 2018, albumin as a nutrition indicator and Neutrophil Lymphocyte-Ratio (NLR) as an indicator of inflammatory and immune response. The value 2.44 was taken as the cut-off point for high NLR. Results: Were included 96 patients. The average age was 63.5 years ± 12.8, the male: female ratio was 1: 1, 80.2% came from the region of the coast of Peru; 70.8% had an advanced clinical stage and 85.4% corresponded to tumor size T3 and T4. 64% presented undifferentiated histological grade and 30.1% showed evidence of metastasis. The mean NLR was 2.94 ± 1.7, and albumin was 3.64 g / dl ± 0.6. In the bivariate analysis, a significant association was found between the high level of NLR and the advanced clinical stage (OR: 4.46 95% CI 1.65-13.27 p <0.001), and between low levels of serum albumin with advanced stage (OR: 13.02 95% CI 1.78-563.36 p <0.005). Conclusion: A late diagnosis was found in 70% of the patients. High NLR as an indicator of inflammatory response and low albumin as an indicator of nutrition are predictors of advanced clinical stage in gastric cancer.

RESUMO

La cuantificación de la carga viral en sangre del Virus Epstein Barr (VEB) ha demostrado ser útil como marcador diagnóstico y pronóstico en específicos tipos de linfomas asociados al virus. 59 pacientes con desórdenes linfoproliferativos fueron reclutados al diagnóstico y se les realizó un estudio de carga viral para la determinación del DNA del VEB en sangre total. Se incluyeron: 46 Linfomas difuso de Células Grandes B Difuso, 3 Linfomas Hodgkin, 3 Linfomas nasal T/NK, 4 Leuce-mia/lymphoma T del Adulto (ATLL), 1 Linfoma T periférico no especificado, 1 Linfoma T paniculítico y 1 Linfoma Hidroa vaciniforme-like. Los resultados arrojaron: 13 casos positivos (rango 0.25-46,400 copies/ul): 7 fueron LCGBD, 2 Linfomas T/NK nasal, 2 ATLL, 1 Linfoma Hodgkin y 1 Linfoma Hidroa vaciniforme–like. 11/13 casos positivos tuvieron estudio de EBER-CISH en tejido tumoral, el cual fue positivo en todos los casos. El estudio sugiere que la cuantificación en sangre total del DNA del VEB correlaciona con la presencia del virus en células tumorales y podría ser útil como biomarcador diagnóstico.


Cuantification of viral blood load for EBV has demonstrated to be useful as marker in diagnosis and prognosis in diferent specific lymphomas related to virus. 59 patients with diverse lymphoprolife-rative disorders were recluted at diagnosis to evaluate viral load of EBV DNA in whole blood. We included: 46 Diffuse large B cell Lymphoma (DLBCL), 3 Hodgkin Lymphoma, 3 T/NK nasal type lym-phoma, 4 Adult T Leukemia/lymphoma (ATLL), 1 T cell lymphoma unspecified, 1 T panicullitic lym-phoma and 1 Hydroa vacciniform –like lymphoma . Results showed: 13 cases were positive (range 0.25-46,400 copies/ul): 7 were DLBCL, 2 T/NK nasal type Lymphoma, 2 ATLL, 1 Hodgkin Lymphoma y 1 Hidroa vacciniforme–like lymphoma. 11/13 positive cases had EBER-CISH in tumoral tissue and it was positive in all cases.This study suggests cuantification in total whole blood for EBV DNA correlates with the presence of EBV in tumoral cells and it could be a useful diagnostic biomarker.

RESUMO

La positividad al HER2 se plantea como un factor pronóstico negativo en Cáncer Gástrico (CG), correlacionando con pobres tasas de sobrevida. Los reportes de tasas de positividad al HER2 en CG varían ampliamente (6-35%). El objetivo del estudio fue determinar la tasa de positividad y describir las características clínicas y patológicas de los CG Her2(+). Los tumores CG fueron centralmente screneados para inmunohistoquímica y FISH. 9% de loscasos fueron positivos, encontrándose mayor positividad en los estadios avanzados (III/ IV) vs. los estadios tempranos (I/II)(p= 0.045); en el tipo histológico intestinal vs. mixto/ difuso ( p=0.03 ) y en los cánceres de la unión gastroesofágica vs CG ( p=0.005).


HER2 positivity is thought to be a negative prognostic factor in gastric cancer (GC), correlating with poor survival rates. Reported HER2-positivity rates in GC have varied widely (6-35%).Objetive of this study is to determine rate of positivity and describe clinical and pathological characteristics of HER-2(+) GC. 100 GC tumour samples were centrallyscreened by immunohistochemistry and FISH. 9% of cases were positive . More positivity HER2 was found in advanced stages (III/IV) vs. early stages (I/II)(p=0.045) ; intestinal histology subtype vs diffuse/ mixed (p=0.045) and gastro-oesophageal junction cancervs GC ( p=0.005).

RESUMO

Introducción: varias revisiones y guías de manejo de Micosis Fungoides (MF) y Síndrome Sézary (SS) han sido publicados. Sin embargo, estrategias terapeúticas para esta entidad varían entre instituciones y países. Existen pocos estudios fase III que permitan tomar decisiones en el tratamiento de MF/SS. Por tanto éste es frecuentemente determinado por las experiencias institucionales. Objetivo: con el objeto de sumarizar la evidencia disponible y revisar las mejores prácticas, es que se realizó un Consenso Peruano llevado a caboen Setiembre 2008 para establecer guías de diagnóstico y tratamientode MF/SS. Resultados: este artículo revisa los criterios clínicos, histopatológicos y terapéuticos de MF/SS.


Background: Several reviews and guidelines on the management of Mycosis Fungoides (MF) and Sézary syndrome (SS) have been published; however, treatment strategies for patients with MF/SS vary from institution to institution and among countries. There are few phase III trials to support treatment decisions for MF/SS and treatment is often determined by institutional experience. Objetive: In order to summarise the available evidence and reviewbest practices, Peruvian Consensus met in September 2004 to establish guidelines for the diagnosis and treatment of MF/SS. Results: This article reviews hystopatologic, clinic and therapeutic criteria of MF/SS.

RESUMO

Introducción: Foxp3 es un gen regulatorio clave requerido para el desarrollo y función de las células T regulatorias CD25+ y CD4+, una subpoblación de células T especializadas en el mantener el balance entre la inmunidad y la tolerancia (Treg) Objetivo: determinar la especificidad y el valor pronóstico de la expresión de Foxp3 en el linfoma de células T. Material y método: estudio retrospectivo en 47 pacientes con Linfoma T en el Hospital Nacional Edgardo Rebagliati Martins, EsSalud durante el período 1997- 2004. Resultados: la expresión de Foxp3 en células tumorales fue detectado en 8/33 (24 por ciento) casos de la Leucemia /Linfoma T del Adulto (ATLL) y en 2/8 (28 por ciento) linfomas T periféricos no especificados (LTPNE) . No hubo diferencia estadística en sobrevida global entre el ATLL Foxp3 (+) y el ATLL Foxp3 (-). El Foxp3 está expresado en diferentes Linfomas T y no es un marcador específico para la identificación de ATLL. Conclusión: la expresión de Foxp3 puede darse en ATLL como en LTPNE.


Introduction: Foxp3 is a key regulatory gene required for CD25+ and CD4+ regulatory T-cells development and function (Treg), a cell subpopulation specialized in maintaining a balance between immunity and tolerance. Objective: To determine the specificity and prognostic value of Foxp3 expression in T-cell lymphoma. Material and Methods: A retrospective study carried out in 47 patients with T-cell lymphoma in Edgardo Rebagliati-Martins Hospital, EsSalud (Peruvian Social Security), from 1997 to 2004. Results: The expression of Foxp3 in tumoral cells was detected in 8/33 (24 per cent) ATLL (adult t-cell leukemia/lymphoma) cases and in 2/8 (29 per cent) LTPNE cases. There was no statistically significant difference in overall survival between ATLL Foxp3 (+) and ATLL Foxp3 (-). Foxp3 is expressed in different T-cell lymphoma types, and it is not a specific marker for the dientification of ATLL cases. Conclusion: Foxp3 expression can be seen both in ATLL as in LTPNE.

RESUMO

Introducción: la multifactorialidad del cancer humano es claramente reconocida. Últimamente se viene asociando virus de la familia del papiloma virus humano (HPV) como condicionante de carcinoma epidermoide de esofago. Caso clínico: describimos el primer caso a nivel de Latinoamérica de un cáncer de esófago con presencia de papilomavirus humano 16 en un trasplantado renal. La paciente de 59 años de edad fue sometida a un trasplante renal once años antes por un síndrome nefrótico de causa no determinada. Recibía inmunosupresores basados en ciclosporina, prednisona y micofenolato de manera initerrumpida. Tres meses antes del diagnóstico la paciente empieza a presentar de manera progresiva disfagia a sólidos asociada a baja ponderal . El estudio endoscópico alto demostró la presencia de una lesión proliferativa ulcerada en tercio medio de esófago. La biopsia esofágica demostró un carcinoma epidermoide. El estudio por PCR para papilomavirus humano subtipo 16 en el tejido tumoral mostró positividad.


Introduction: Being multifactorial is a clearly recognized feature of cancer in humans. Recently, some members of the human papillomavirus family have been associated as conditioning factors for the development of epidermoid esophageal carcinoma Clinical case: This is the first case described in Latin America of an esophageal cancer with the presence of a human papillomavirus-16 in a patient undergoing renal transplantation. This patient, a 59-year old woman, had a renal transplant eleven years ago because of a nephritic syndrome with an unknown cause. She received immunosuppression using cyclosporine, prednisone and mycophenolate, never interrupting therapy. Three months before diagnosis, the patient presented with dysphagia to solid foods, associated to weight loss. An upper gastrointestinal endoscopy showed the presence of a proliferative ulcerated lesion in the middle third of the esophagus. A biopsy of this lesion showed an epidermoid carcinoma.

RESUMO

Introducción: bexaroteno es un rexinoide aprobado en el tratamiento de estadios tempranos y avanzados del linfoma cutáneo de células T (LCCT). Caso Clínico: el presente reporte de casos mostramos los resultados del empleo de bexaroteno en dosis bajas más fototerapia o Interferon alfa 9 millones en el tratamiento del LCCT. Ocho pacientes fueron tratados , cinco fueron Micosis fungoides, dos Linfoma Epidermotrópico CD8 agresivo y uno fue un Síndrome Sézary. La respuesta global fue del 62.5 por ciento (5/8) y la duración media de respuesta fue de 20 meses. El bexaroteno en dosis bajas en combinación a fototerapia o interferon alfa 2a puede ser efectivo en el tratamiento del LCCT.

RESUMO

Primary colorectal lymphoma is a very rare disease. Primary colorectal lymphoma of diffuse large B-cells is a more frequent subtype representing 1% of all colon diseases. In a retrospective study, the clinical characteristics and treatment course of primary colorectal lymphoma of diffuse large B-cells between 1997 and 2003 were reviewed. According to Dawson's criteria, fourteen cases were identified. The average age was 65 and the ratio of men to women was 1:3. The most frequent signs and symptoms were abdominal pain (78%), diarrhea (49%) and abdominal tumor (35%). The most frequently involved regions were the cecum (42%), ascending colon (21%) and rectum (21%). Six were in Stage I, four in Stage II and four in Stage III. The 5-year survival per stage was 26, 11 and 5 months, respectively. Primary colorectal lymphoma of diffuse large B-cells usually affects the right part of the colon in an aggressive manner.
