RESUMO

Introducción El objetivo de este estudio fue evaluar el impacto del tamaño tumoral y la invasión de la rete testis en la supervivencia libre de progresión de nuestros pacientes con seminoma testicular en estadio I. También se llevó a cabo una revisión bibliográfica. Material y métodos Se realizó un estudio observacional retrospectivo incluyendo a los pacientes con seminoma en estadio I entre enero de 2010 y julio de 2022. Se compararon los pacientes sin factores de pronóstico favorable (Grupo A) con pacientes que presentaban factores de pronóstico desfavorable (Grupo B). Se utilizaron curvas de Kaplan-Meier y pruebas de log-rank para comparar la supervivencia libre de progresión (SLP) entre estos grupos. La significación estadística se consideró a p ≤ 0,05. Resultados Se incluyeron 55 pacientes en este estudio. Veinte pacientes (36,4%) tenían un pronóstico favorable (grupo A) y 35 (63,6%) presentaban factores de pronóstico desfavorable (grupo B). La edad media fue similar en ambos grupos (media ± desviación estándar), 38,62 ± 9,04 años. El tiempo medio de seguimiento fue de 63,5 ± 33,6 meses. Todos los pacientes del grupo A y 25,7% de los pacientes del grupo B se sometieron a vigilancia activa (VA). Veintiséis pacientes (74,3%) del grupo B fueron tratados con un ciclo de carboplatino adyuvante. Tres pacientes sufrieron recidiva en ganglios retroperitoneales (10,3%), todos tratados con tres ciclos de bleomicina, etopósido, y cisplatino (BEP), presentando remisión completa de la enfermedad. No se encontraron diferencias estadísticamente significativas en la SLP entre los grupos A y B (log-rank p = 0,317). Conclusiones La individualización del tratamiento adyuvante en el seminoma estadio I es esencial para evitar los efectos adversos derivados del mismo. (AU)


Introduction The aim of this study was to evaluate the impact of tumour size and rete testis invasion in progression free survival of our patients with stage I testicular seminoma. A literature review is also made. Material and methods A retrospective observational study was performed. We included patients with stage I seminoma between January 2010 and July 2022. Patients without factors of poor prognostic –Group A– were compared with patients with factors of poor prognostic –Group B–. Kaplan-Meier curves and log-rank testing were used to compare progression free survival (PFS) between these groups. Statistical significance was considered at P ≤ .05. Results 55 patients were included in this study. 20 patients (36.4%) were of good prognostic –Group A– and 35 (63.6%) had factors of poor prognostic –Group B–. The mean age was similar in both groups (mean ± standard deviation), 38.62 ± 9.04 years. The mean follow-up time was 63.5 ± 33.6 months. All the patients in group A and 25.7% of the patients in group B underwent active surveillance (AS). 26 patients (74.3%) of the patients in Group B were treated with one cycle of adyuvant carboplatin. Three patients suffered a relapse with retroperitoneal lymph nodes (10.3%), all of them were treated with three cycles of BEP, with a complete response of the disease. No statistical significant differences were found in PFS between Group A and B (log Rank P = .317). Conclusions Individualization of adjuvant treatment in stage I seminoma is important, avoiding the adverse effects derived from them. (AU)

RESUMO

Purpose: To study the association between various tissue types, benign and malignant proportion and preoperative serum alpha-fetal protein (AFP) value and benign and malignant testicular tumors, to provide help for clinical diagnosis and treatment in young male players. Methods: The clinical data of 122 pediatric testicular tumors of young players admitted to our hospital from October 2013 to December 2021 were collected for retrospective chart review. According to the pathological test results, the tissue type, age, benign and malignant proportion and preoperative AFP level and benign and malignant associations between testicular tumors were analyzed. Results: A total of 122 pediatric testicular tumors of young players aged 0.01 to 14 years old, 114 young players (93.4%) were primary testicular tumors, 8 young players were secondary malignant tumors (6.6%), and 7 of them were leukemic cell infiltration. Of the 114 primary testicular tumors, 84 were benign (73.7%), 43 left, 41 right, 0.01-12 median 3.29,60 teratas, 71.4% of primary benign tumors, 30 malignant (26.3%), 16 left, 14 right 0.44-4.33, median 2.81, including 26 yolk sac tumors (86.7% of primary testicular malignancy), 2 mixed cell tumors and two rhabdomyosarcoma tumors.In the primary testicular tumors, 100 young players cases were derived from germ cell tumors (87.7%). His children had preoperative serum AFP levels, including 19 children <6 months of age, including 11 mature teratoma, 4 immature teratoma, and 4 yolk sac tumors, with an AFP range of 5.4-14424.12ng/ml, 46.1-713.26ng/ml, 2620.34-17597.67ng/ml.A total of 81 children over 6 months of age, including 43 mature teratoma (AFP range 0-92.18ng/ml), 2 immature teratoma (AFP 0.78-36.4ng/ml), 22 yolk sac tumors (AFP367.7-26630.3ng/ml), 12 dermoid cysts (AFP 0-4.6ng/ml), and 2 mixed germ cell tumors (AFP =5462.38ng/ml, 16018.65ng/ml, respectively).

RESUMO

Introducción: En la actualidad no existe evidencia que determine de forma concreta la relación entre microlitiasis testicular sola o en relación con otros factores como elemento de riesgo para el desarrollo de tumores testiculares, además de no existir recomendaciones claras sobre el seguimiento de esta condición. El objetivo de esta revisión es aportar con una guía para el seguimiento de estos pacientes basado en la evidencia de la literatura. Métodos: Se realizó una revisión de literatura durante diciembre de 2021 en PubMed, base de datos Cochrane y TRIP Database, la selección de los artículos se realizó por medio de las recomendaciones de PRISMA 2020. Resultados: Un total de 4 revisiones sistemáticas fueron seleccionadas para el trabajo final. Se logró determinar que la asociación de microlitiasis testicular a otros factores de riesgo incrementa aún más el riesgo de desarrollo de cáncer, sin embargo, en ausencia de estos factores el riesgo el riesgo de cáncer testicular es similar al de la población general. Conclusiones: En pacientes con riesgo de desarrollo de cáncer testicular se recomienda un seguimiento individualizado dependiendo de la edad, de los factores de riesgo asociados, de la infertilidad y del síndrome de disgenesia testicular, para poder determinar la necesidad de seguimiento versus realización de biopsia testicular. (AU)


Introduction: Currently, no evidence determines the relationship between testicular microlithiasis by itself, or in relation with other factors, as a risk factor for the development of testicular tumors. There are no clear recommendations regarding the follow-up of this medical condition. Therefore, this review aims to provide a guide to monitoring these patients, supported by the literature. Methodology: A literature review was carried out in December 2021 in PubMed, Cochrane, and TRIP Database, and the selection of the articles was made following the PRISMA 2020 recommendations. Results: Overall, the four systematic reviews chosen to conduct the final study determined that the combination of microlithiasis testicular with other risk factors further increased cancer development. However, the likelihood of testicular cancer risk is similar to that of the general population. Conclusions: Patients at risk of developing testicular cancer should undergo personalized monitoring according to their age, associated risk factors, infertility, and testicular dysgenesis syndrome to determine their follow-up needs or perform a testicular biopsy.

RESUMO

INTRODUCCIÓN Y OBJETIVOS: El objetivo de este estudio retrospectivo fue analizar la densidad de los ganglios linfáticos (GL) en la disección de los GL retroperitoneales (DGLRP) para evaluar la masa residual tras quimioterapia como factor predictivo de recurrencia en pacientes con cáncer testicular de células germinales (CTCG). MATERIALES Y MÉTODOS: Se revisaron retrospectivamente los datos de 185 pacientes operados por CTCG entre diciembre del 2004 y febrero del 2017. Se calculó la densidad de los GL. Los pacientes se compararon estadísticamente en términos de características demográficas, características tumorales, niveles de marcadores tumorales séricos, estrategias de tratamiento y resultados patológicos según los subtipos de CTCG. Se realizó un análisis de correlación para determinar los parámetros relacionados con la enfermedad recurrente. RESULTADOS: La mediana de seguimiento fue de 79 (31-179) meses y la mediana de edad de los pacientes fue de 23 (16-71). El tamaño medio del tumor fue de 4 (1-18) cm. Cinco (2,7%) pacientes tenían enfermedad metastásica en el momento del diagnóstico inicial. Se detectó seminoma, TCG no seminomatoso y CTCG de tipo mixto en 62 (33,5%), en 60 (32,4%) y en 63 (34,1%) pacientes, respectivamente. Tras la orquiectomía inguinal, 48 (25,9%) pacientes recibieron seguimiento, 126 (68,1%) pacientes se sometieron a quimioterapia y 11 (5,9%) pacientes recibieron radioterapia. Un total de 21 (11,4%) pacientes se sometieron a DGLRP posquimioterapia. Se observó recurrencia precoz y tardía en 3 (1,6%) y 2 (1,1%) pacientes, respectivamente. Se encontró una correlación negativa leve/moderada, pero significativa, entre la recurrencia y el número de GL con depósitos metastásicos y la densidad de los GL (r = -0,490, p = 0,024 y r = -0,450, p = 0,041, respectivamente). CONCLUSIONES: Hubo una correlación negativa entre el número de GL con depósitos metastásicos y la densidad de GL con la enfermedad recurrente


INTRODUCTION AND OBJECTIVES: In this retrospective study, we aimed to evaluate lymph node (LN) density in retroperitoneal lymph node dissection (RPLND) to analyze whether residual mass after chemotherapy might behave as predicting factor for recurrence in patients with germ cell testicular cancer (GCTC). MATERIALS AND METHODS: The data of 185 patients that were operated between 12/2004 and 02/2017 because of GCTC were reviewed retrospectively. LN density was calculated. The patients were compared statistically in terms of demographic features, tumor characteristics, serum tumor marker levels, treatment strategies, and pathological results according to GCTC subtypes. Correlation analysis was performed to determine the parameters related to recurrent disease. RESULTS: The median follow-up was 79 (31-179) months and the median age of the patients was 23 (16-71). The median tumor size was 4 (1-18) cm. Five (2.7%) patients had metastatic disease at initial diagnosis. Seminoma, non-seminomatous-GCT and mix type-GCTC was detected in 62 (33.5%), 60 (32.4%) and 63 (34.1%) patients, respectively. Following inguinal orchiectomy, 48 (25.9%) patients underwent follow-up, 126 (68.1%) patients underwent chemotherapy and 11 (5.9%) patients underwent radiotherapy. A total of 21 (11.4%) patients underwent post-chemotherapy RPLND. Early and late recurrence was seen in 3 (1.6%) and 2 (1.1%) of the patients, respectively. A mild to moderate, negative, but significant correlation was found between the recurrence and the number of LNs containing metastatic deposits and LN density (r = -0.490, P = .024 and r = -0.450, P=.041, respectively). CONCLUSIONS: There was a negative correlation between the number of LNs containing metastatic deposits and LN density and recurrent disease

RESUMO

INTRODUCCIÓN: Los tumores germinales del sistema nervioso central deben ser correctamente diagnosticados, pues su tratamiento suele ser eficaz y no siempre requieren cirugía. Los objetivos del estudio son describir las manifestaciones endocrinas de estas neoplasias y comparar su momento de aparición con el de las alteraciones neurológicas y visuales. PACIENTES Y MÉTODOS: Revisión de historias de pacientes menores de 14 años atendidos en una unidad de endocrinología pediátrica desde 2000 hasta 2018. Pruebas estadísticas: Wilcoxon y Fisher. RESULTADOS: Se estudió a 12 pacientes (10 mujeres) con una edad al diagnóstico de 9,4±1,7 años y un tiempo de seguimiento de 5,5±3,0 años; 10 presentaban tumores de la región selar, uno pineal y uno bifocal. Las alteraciones clínicas que llevaron al diagnóstico eran neurológicas o visuales en 9casos y hormonales en 3. De los que consultaron por síntomas neurológicos o visuales, 7 refirieron previamente alteraciones hormonales, luego, estas estaban presentes en 10 de los niños al diagnóstico; la más frecuente fue la diabetes insípida central (8 casos). El periodo medio de presencia de síntomas endocrinológicos previos al diagnóstico fue de 25,0±26,2 meses, mucho más largo que el de los neurooftalmológicos, de 2,0±2,1 meses (p = 0,012). CONCLUSIONES: Casi todos los tumores germinales intracraneales presentaron al diagnóstico manifestaciones endocrinas, la más frecuente de las cuales fue la diabetes insípida central. Los síntomas hormonales suelen presentarse bastante antes que los neurooftalmológicos. La correcta valoración clínica y endocrinológica puede adelantar el diagnóstico de estos tumores


INTRODUCTION: Central nervous system germ cell tumors need to be adequately diagnosed because their treatment is usually effective and they do not always require surgery. The study objectives are to describe the endocrine manifestations of these tumors and to compare the time of their onset to that of the occurrence of neurological and visual changes. PATIENTS AND METHODS: The medical histories of patients under 14 years of age seen at a pediatric endocrinology unit between 2000 and 2018 were reviewed. Wilcoxon and Fisher statistical tests were performed. RESULTS: We found 12patients (10 females) with an age at diagnosis of 9.4±1.7 years and a follow-up time of 5.5±3.0 years, 10with tumors in the sellar region, and each one with a pineal gland and a bifocal tumor. Clinical changes leading to diagnosis were neurological and/or visual in 9patients and hormonal in three. Seven patients diagnosed on the basis of neurological or visual symptoms had previously reported hormonal changes, giving us a total of 10 children at diagnosis (the most common diagnosis was central diabetes insipidus, found in 8). Endocrine symptoms had been present before diagnosis for 25.0±26.2 months, considerably longer than neuro-ophthalmological complaints (2.0±2.1 months, p = 0.012). CONCLUSIONS: Almost all intracranial germ cell tumors have associated endocrine manifestations at diagnosis, with central diabetes insipidus the most common. Hormonal symptoms usually appear long before neuro-ophthalmological manifestations. Adequate clinical and endocrinological assessment may allow for an earlier diagnosis of these tumors

RESUMO

INTRODUCCIÓN: La microlitiasis testicular (MT) es un hallazgo clínico poco frecuente en población general masculina; dichas calcificaciones son reportadas por ultrasonidos testiculares y constituyen un hallazgo incidental. La presencia de MT se encuentra asociada a carcinoma testicular. OBJETIVOS: Analizar la relación entre variables clínicas, demográficas, comorbilidades y marcadores tumorales con la presencia o ausencia de microlitiasis en sujetos con cáncer testicular. MATERIAL Y MÉTODOS: Estudio retrospectivo donde se incluyó un total de 66 pacientes con diagnóstico de carcinoma testicular del año 2012 al 2017 en un hospital del noreste de México. Se dividió el total de los pacientes en 2 grupos según la presencia o ausencia de MT, y se analizaron las características clínicas de estos. RESULTADOS: La prevalencia general de MT fue de un 31,8%. El principal tumor observado en los reportes de patología fue el tumor de células germinales no seminomatoso (54,4%). La incidencia de metástasis a órganos fue del 27,3%. No se encontraron diferencias estadísticamente significativas al comparar las variables de interés en el grupo con y sin MT. Se encontró una relación entre la elevación de alfa-fetoproteína y los tumores no seminomatosos (p = 0,003). CONCLUSIONES: De acuerdo con los resultados obtenidos, se puede decir que las MT constituyen un hallazgo clínico que no tiene relación con el pronóstico de la enfermedad y que además no se relacionan con ninguna de las comorbilidades y datos clínicos analizados


INTRODUCTION: Testicular microlithiasis (TM) is an uncommon finding in general male population. These calcifications are reported by testicular ultrasound performed by some testicular pathology and constitute an incidental finding. The presence of TM is regularly associated to testicular neoplasms. OBJECTIVES: To investigate the relationship between clinical and demographic factors, comorbidities and tumor biomarkers, and the presence or absence of microlithiasis in patients with testicular cancer. MATERIAL AND METHODS: A retrospective study including a total of 66 patients diagnosed with testicular carcinoma from 2012 to 2017 in a hospital in Northeastern Mexico. The total of patients was divided into 2 groups according to the presence or absence of MT and the clinical features of these were analyzed. RESULTS: There was a general prevalence of TM of 31.8%. The main tumor found in the pathology reports corresponded to the non seminomatous germ cells tumor (54.4%). The incidence of metastasis to organs was of 27.3%. No statistically significant differences were found when comparing the variables of interest in the group with and without MT. A relationship was found between the elevation of alpha-fetoprotein and non-seminomatous tumors compared to seminomatous tumors (PY=Y.003). CONCLUSIONS: According to the results obtained, it can be suggested that TM is a clinical finding that is not related to the prognosis of the disease or any of the comorbidities and clinical data analyzed in our study

RESUMO

INTRODUCCIÓN Y OBJETIVOS: Los tumores ováricos son raros en la infancia y representan entre el 1 y el 5% de todos los tumores sólidos. Nuestro objetivo es conocer las características epidemiológicas, los subtipos histológicos y el manejo terapéutico de los tumores sólidos ováricos de la población pediátrica de la provincia de Córdoba. MATERIAL Y MÉTODOS: Se realizó un estudio retrospectivo, descriptivo, observacional, en el que se han revisado las historias clínicas de pacientes ≤ 14 años diagnosticadas de tumores sólidos ováricos en un hospital de tercer nivel entre los años 1994 y 2017, excluyéndose los tumores secundarios. Se revisó la edad, la presentación clínica, la lateralidad, la metodología diagnóstica, el tratamiento, la anatomía patológica y la evolución. RESULTADOS: Se revisaron 37 tumores ováricos en 31 pacientes, siendo 6 bilaterales. La edad media fue de 10,3 años (0-14). El 58% debutaron como masa palpable. No existe predominio de lateralidad. Los marcadores tumorales fueron negativos. Se practicó cirugía conservadora en el 29,7% y anexectomía en el 70,3%. Solo un teratoma inmaduro estadio I con gliomatosis peritoneal precisó tratamiento quimioterápico adyuvante postoperatorio. El estudio histológico demuestra un predominio de tumores de células germinales (65%) frente a los de estirpe epitelial (22%). Destacan 3 tumores estromales que corresponden a fibromas (síndrome de Gorlin) y un gonadoblastoma bilateral asociado a síndrome de Frasier. El tipo de tumor más frecuente fue el teratoma quístico maduro (35,1%). Evolución favorable en todos los casos. CONCLUSIONES: Dada la alta tasa de benignidad de los tumores ováricos en la infancia, la cirugía conservadora debe ser de primera elección, sobre todo en los bilaterales. Si existen antecedentes hereditarios, es imprescindible realizar estudios genéticos moleculares para descartar síndromes asociados


INTRODUCTION AND OBJECTIVES: Ovarian tumours are rare in childhood, and account for 1-5% of all tumours. The aim of this study is to determine the epidemiological features, histological subtypes, and therapeutic management of ovarian solid ovarian tumours of the paediatric population of the province of Cordoba, in Spain. MATERIAL AND METHODS: A retrospective, descriptive, observational and institutional study was conducted in which a review was made of the clinical histories of patients younger than 14years-old diagnosed with ovarian tumours, excluding secondary tumours in a University Hospital between 1994 and 2017. A review was carried out on the age, clinical presentation, laterality, diagnostic methodology, treatment, histopathology, and evolution of these tumours. RESULTS: A total of 37 ovarian tumours were reviewed in 31 patients, 6 of them being bilateral. The mean age was 10.3 (0-14) years, with 58% presenting as a palpable mass. There was no predominance of laterality. The tumour markers were negative. Conservative surgery was performed in 29.7% and adnexectomy in 70.3%. Only one case required post-operative adjuvant chemotherapy treatment (stage I immature teratoma with peritoneal gliomatosis). The histological study shows a predominance of germ cell tumours (65%) against those of epithelial lineage (22%). There were 3 stromal tumours that corresponded to fibroma (Gorlin syndrome), and bilateral gonadoblastoma associated with Frasier syndrome. The most frequent type of tumour was mature cystic teratoma (35.1%). There were no complications in the follow-up. CONCLUSIONS: Given that most childhood ovarian tumours are benign, conservative surgery is considered as the first choice, being even more important in bilateral tumours. If there is a family history, it is essential to carry out molecular genetic studies, to rule out associated syndromes

RESUMO

Introduction: The immune system plays an essential role in the organism's response to cancer. Several hematological markers can influence prognosis and survival of patients. The objective of this study is to determine their prognostic value in testicular germ cell tumors. Material and methods: Retrospective cohort study on 164 patients with germ cell tumors. Clinical, analytical, histological and evolutionary data were collected. The absolute neutrophil and absolute platelet counts, neutrophil-lymphocyte (NLR), platelet-lymphocyte and lymphocyte-monocyte ratios were estimated at diagnosis. The association that these markers can have with the classic prognostic factors, as well as their effect on prognosis and survival, have been analyzed. Results: 17.7% had NLR > 4 and 14.6% ANC > 8000/μL. These patients presented higher percentages of residual disease and stage II-III tumors. Patients with elevated absolute neutrophil showed also higher percentages of progression and exitus. 7.3% presented absolute platelet > 400,000/μL. These patients obtained higher rates of residual disease, nonseminomatous and stage III tumors. 28.4% showed platelet-lymphocyte values > 150. This data was associated to higher percentages of residual disease, progression, stage II and III tumors and seminomatous tumors. 83.3% had a lymphocyte-monocyte > 3. These patients presented: higher tumor markers in normal range, decreased residual disease rates and higher percentages of stage I and II tumors. The mean survival time was shorter in patients with NLR > 4 and absolute neutrophil > 8000/μL. The ROC curves showed significance in the prediction of progression and values of lymphocyte-monocyte >3, and prediction of survival and values NLR > 4. Conclusion: Our results indicate that the analyzed hematological markers are associated with poor prognoses at diagnosis. Therefore, their use in daily clinical practice can be a valuable tool in the diagnosis and prognosis of patients with testicular germ cell tumors


Introducción: El sistema inmune ejerce un papel clave en la respuesta del organismo frente al cáncer. Existen diversos marcadores hematológicos que pueden influir en el pronóstico y supervivencia de los pacientes. El objetivo de este estudio es determinar su valor pronóstico en tumores testiculares de células germinales. Material y métodos: Estudio de cohortes retrospectivo sobre 164 pacientes con tumores testiculares de células germinales. Se recogieron datos clínicos, analíticos, histológicos y evolutivos. Se estimaron, al diagnóstico, el recuento total de neutrófilos y plaquetas, la ratio neutrófilo-linfocito (RN/L), plaqueta-linfocito(RP/L) y linfocito-monocito (RL/M). Se analizó la relación que estos marcadores pueden tener sobre los factores pronósticos clásicos, así como sobre el pronóstico y supervivencia. Resultados: Un 17,7% tuvieron una RN/L > 4 y un 14,6% un RNT > 8000/μL. Estos enfermos, presentaron mayor porcentaje de enfermedad residual y tumores en estadios II y III. Los enfermos con recuento total de neutrófilos elevado también tuvieron mayor porcentaje de progresión y éxitus. Un 7,3%, tenían un recuento total de plaquetas > 400000/μL. Estos enfermos tuvieron un mayor porcentaje de tumores no seminomatosos, de enfermedad residual y tumores en estadio III. El 28,4% mostraron valores RP/L>150, asociándose este dato a mayor porcentaje de tumores seminomatosos, enfermedad residual, estadios II y III y progresión. El 83,3% tuvieron una RL/M > 3. Estos enfermos presentaron: mayor porcentaje de marcadores tumorales en rango normal, menor porcentaje de enfermedad residual y mayor porcentaje de pacientes en estadio I y II. El tiempo medio de supervivencia fue menor en pacientes con RN/L > 4 y con recuento total de neutrófilos > 8.000/μL. Las curvas ROC mostraron significación en la predicción de progresión y valores de RL/M > 3, y predicción de supervivencia y valores RN/L > 4. Conclusión: Nuestros resultados indican que los marcadores hematológicos analizados se asocian situaciones de mal pronóstico en el momento del diagnóstico. Por tanto, su utilización en la práctica clínica diaria puede ser considerada como una herramienta más en el diagnóstico y pronóstico de pacientes con tumores testiculares de células germinales de testículo

RESUMO

Los hemangiomas son los tumores hepáticos benignos más prevalentes, por lo que su hallazgo incidental en estudios radiológicos de pacientes oncológicos es muy frecuente. Presentamos el caso de una paciente con diagnóstico de teratoma ovárico inmaduro de alto grado y lesiones hepáticas con criterios radiológicos típicos de hemangiomas que, en el curso del tratamiento quimioterápico adyuvante con BEP (cisplatino, etopósido y bleomicina), experimentan una disminución significativa de su tamaño. La respuesta de los hemangiomas hepáticos inducida por determinados quimioterápicos puede simular la respuesta de las metástasis hepáticas, y puede inducir a una interpretación errónea de las imágenes. El objetivo de este artículo es documentar la existencia de una «respuesta» de los hemangiomas inducida por la quimioterapia, en concreto cuando se usa la terapia combinada BEP, ya que ha sido escasamente publicada en la literatura y, según nuestro conocimiento, nunca en el curso del tratamiento de un teratoma inmaduro del ovario


Liver hemangiomas are the most common benign primary tumors of the liver. Due to their high prevalence, incidental finding of hemangiomas during radiological workup of oncologic patients is not uncommon. We present the case of a patient diagnosed of an ovarian immature teratoma and hepatic lesions with typical radiological appearance of hemangiomas that decreased in size during adjuvant chemotherapy with BEP regimen (cisplatin, etoposide and bleomycin). Chemotherapy-induced shrinkage of hepatic hemangiomas can mimic the response of liver metastases to chemotherapy and may induce erroneous interpretations. The purpose of this report is to describe a chemotherapy-induced response of liver hemangiomas, especially when BEP combination is used. To date this observation has been barely reported in the literature and, to our knowledge, this is the first documented case of chemotherapy-induced response of liver hemangiomas in a patient diagnosed of an ovarian immature teratoma

RESUMO

Teratoma is a common form of germ cell tumors composed of multiple tissues foreign to the site in which arise with a histological representation of all three germ cell layers. Intracranial teratomas are very rare. In this study, we report three cases of intracranial teratomas with an interesting clinical course, neuroradiology, and outcome. In addition, we review the literature and convey important messages to the neuroscience community regarding issues related to the management of these rare tumors. The present cases are interesting examples of intracranial teratoma in terms of location of the tumor and neuroimaging findings. Delay in surgical intervention may complicate the course of the disease with progressive enlargement of tumors and development of complication including hydrocephalus. Using endoscopic surgical techniques may emerge as the preferred intervention option as compared to other traditional methods. We recommend the establishment of a national and international registry for intracranial tumors


El teratoma es un tipo frecuente de tumor de células germinales compuesto por múltiples tejidos ajenos a la zona en que aparecen con una representación histológica de las 3 capas de células germinales. Los teratomas intracraneales son muy poco frecuentes. En este estudio, se presentan 3 casos de teratomas intracraneales con una evolución clínica, neurorradiología y resultado interesantes. Además, se revisa la bibliografía y se difunde un mensaje importante a la comunidad de las neurociencias respecto a los problemas relacionados con el tratamiento de estos tumores raros. Estos casos son ejemplos interesantes de teratoma intracraneal en términos de localización de los hallazgos tumorales y de neuroimagen. El retraso en la intervención quirúrgica puede complicar la evolución de la enfermedad con la ampliación progresiva de los tumores y el desarrollo de complicaciones, especialmente hidrocefalia. El uso de técnicas quirúrgicas endoscópicas aparece como la opción de intervención preferida en comparación con otros métodos tradicionales. Se recomienda el establecimiento de un registro nacional e internacional de tumores intracraneales

RESUMO

Management of testicular cancer has evolved through many breakthroughs. The decades of zeal to improve oncologic adequacy and to decrease morbidity has led to the current scientific knowledge of retroperitoneal lymph node dissection templates. Retroperitoneal lymph node dissection (RPLND) has potential for staging, prognostication and therapeutic importance in the management of testicular malignancy. RPLND has overcome limitations of current imaging which understage 30% of stage I disease and overstage 25-30% of stage II disease. For low-volume disease, RPLND is curative in up to 90% cases without adjuvant therapy and has important role in postchemotherapy residual disease. Risk of recurrence after RPLND is 1% and follow-up imaging can be limited, thus avoiding their potential risk of radiation exposure. RPLND reveals vital information of disease nature and guide adjuvant therapy. Despite the long evolution period, certain controversies still surround RPLND. We aim to refine this challenging management in the following manuscript based on available evidence (AU)

RESUMO

Purpose. Non-epithelial ovarian cancers (NEOCs) are rare diseases. Despite their overall good prognosis, the best management and current prognostic factors remain unclear. The objective of our study was to assess the clinical and pathological features of NEOC patients treated in our institution in the last 15 years and to explore risk factors for relapse and survival. Methods/patients. All patients with a pathological diagnosis of NEOC referred to the medical oncology department at Hospital Universitario Virgen del Rocio between 1999 and 2014 were included. Demographics, tumor characteristics, treatment procedures, and clinical follow-up were retrospectively collected. Risk factors for disease-free survival (DFS) and overall survival (OS) were assessed. Results. Fifty-seven patients were included, 33 (58 %) had a sex cord-stromal tumor (SCST) and 24 (42 %) had a germ-cell tumor (GCT). Median age, non-conservative surgery rates and DFS were lower in the GCT cohort; however, salvage chemotherapy led to a high proportion of complete responses in this group translating into a 90 % 3-year OS rate in both NEOC subtypes. The only identified risk factors statistically significant were stage and tumour relapse that associated, respectively, with DFS (HR = 8.84; 95 % CI 1.85-42) and OS (HR = 11.02; 95 % CI 1.76-68.7). Conclusions. Despite their rarity, NEOCs remain a highly curable group of neoplasm. In our series, a more conservative treatment approach in ovarian GCTs revealed comparable OS outcomes to SCST. No new risk factors that would help in patient stratification were identified (AU)

RESUMO

INTRODUCCIÓN: Los tumores de células germinales intracraneales son un grupo poco frecuente de tumores en niños. Comprenden un grupo heterogéneo de neoplasias, que aunque comparten un origen común, presentan comportamientos clínicos muy diferentes. PACIENTES Y MÉTODOS: Análisis retrospectivo de las características epidemiológicas e histológicas, las manifestaciones clínicas y la evolución de 20 pacientes diagnosticados de tumor de células germinales intracraneal en el Hospital Infantil Universitario Niño Jesús de Madrid durante los años 1994-2014. RESULTADOS: Se obtuvieron 20 pacientes: 14 niños y 6 niñas. La edad media fue de 11,1 años (rango 2-18 años). Se realizó confirmación histológica en el 95% de los pacientes. De los 20 pacientes, 14 fueron germinomas puros (70%) y 6 tumores de células germinales no germinomas (30%). Las localizaciones más frecuentes fueron pineal (45%) y supraselar (45%). Los síntomas más frecuentes en el momento del diagnóstico en los tumores de localización pineal fueron cefalea y vómitos (77,77%), seguido de alteraciones visuales (44,4%), y en los tumores de localización supraselar, polidipsia y poliuria (100%). En el momento del diagnóstico recibieron radioterapia el 90% de los pacientes y quimioterapia asociada a la radioterapia el 55%. Presentaron recaída tumoral 4 pacientes (20%), de los cuales 3 fallecieron. La supervivencia global fue del 80%, siendo un 85,7% para los germinomas y un 60% para los no germinomas. CONCLUSIÓN: El tipo histológico más frecuente fue el germinoma. Los tumores de células germinales son un grupo heterogéneo de tumores que conllevan un pronóstico diferente, por lo que un adecuado diagnóstico y estadificación es fundamental para planear el tratamiento


INTRODUCTION: Intracranial germ cell tumours are rare in children. They are a heterogeneous group of neoplasms that show different clinical manifestations despite having a common origin. PATIENTS AND METHODS: A retrospective analysis was carried out on the epidemiological and histological characteristics, clinical manifestations, and outcomes of 20 patients diagnosed with intracranial germ cell tumours in the Ni˜no Jesús Children's Hospital of Madrid from 1994-2014. RESULTS: A total of 20 patients were identified: 14 boys and 6 girls. The mean age was 11.1 years (range 2-18 years). Histological confirmation of the diagnosis was obtained in 95% of the patients. Of the 20 patients, 14 were pure germinoma (70%) and 6 non-seminomatous germ cell tumours (30%). The most frequent locations were pineal (45%) and suprasellar (45%). The most frequent clinical symptoms in pineal tumours at diagnosis were headache and vomiting (77.77%), followed by visual disturbances (44.4%). In suprasellar tumours it was polydipsia and polyuria (100%). At diagnosis, 90% of the patients received radiotherapy, and 55% received chemotherapy combined with radiotherapy. There was a relapse in 4 patients (20%), and 3 of them died. Overall survival was 80%; 85.7% for pure germinomas and 60% for non-seminomatous germ cell tumours. CONCLUSIONS: The most common histological subtype was pure germinoma. Germ cell tumours include heterogeneous disease entities that have a variable prognosis. Thus, an accurate diagnosis is vital for patient counselling and treatment planning

RESUMO

Testicular germ cell tumors (TGCTs) are the most common solid tumors in young adult men. They constitute a unique pathology because of their embryonic and germ origin and their special behavior. Genetic predisposition, environmental factors involved in their development and genetic aberrations have been under study in many works throughout the last years trying to explain the susceptibility and the transformation mechanism of TGCTs. Despite the high rate of cure in this type of tumors because its particular sensitivity to cisplatin, there are tumors resistant to chemotherapy for which it is needed to find new therapies. In the present work, it has been carried out a literature review on the most important molecular aspects involved in the onset and development of such tumors, as well as a review of the major developments regarding prognostic factors, new prognostic biomarkers and the possibility of new targeted therapies (AU)

RESUMO

Los tumores germinales suelen aparecer en niñas o en mujeres jóvenes y tener un crecimiento muy rápido. Presentamos un caso de un tumor germinal de tipo yolk sac gigante que apareció en una paciente perimenopaúsica sin otros antecedentes de interés. Actualmente el pronóstico de estos tumores es muy bueno; se pueden conseguir remisiones completas gracias a la cirugía radical y a la poliquiometarapia (AU)


Germ cell tumours usually occur in girls or young women and have a very rapid growth. We present a case of germ cell tumour, type giant "yolk sac", that appeared in a perimenopausal patient with no other relevant history. Currently, the prognosis of these tumours has improved and complete remission can be obtained after radical surgery and polychemotherapy (AU)
