RESUMO

AIM OF THE STUDY: mTOR inhibitors are being used to treat complex vascular anomalies (VA) without response to conventional treatments. We report our results in pediatric patients treated with sirolimus. METHODS: Retrospective review of patients treated with sirolimus between 2014 and 2017, analyzing vascular anomaly type, treatment response and complications. Treatment protocol included patients with complex vascular anomalies, after signing the informed consent. The initial dose was 0.8 mg/m2/12 h, verifying plasmatic levels. Favorable response was defined both in clinical and radiological terms. MAIN RESULTS: Sirolimus was employed in nine patients, median age 14 months old (1 month-14 years), 66% girls. Five complex micro-cystic lymphatic malformations (LM), one multifocal lynphangioendotheliomatosis with thrombocytopenia, one kaposiform lymphangiomatosis, one lymphatic-venous malformation and one kaposiform hemangioendothelioma (KHE) were treated. Median treatment was 4 months (IQR 2-18 months). Resolution or improvement was objectified in four patients (44%). KHE patient presented complete resolution after two months of treatment. Two patients with micro-cystic LM and the one with lymphatic-venous malformation improved after a median treatment of three months. Two patients presented rebound effect after discontinuing treatment. Three patients had hypertransaminasemia and hypercholesterolemia without requiring medical treatment. CONCLUSION: Sirolimus presented mild effects for treatment of complex VA in our study, but was highly resolutive at KHE.


OBJETIVOS: Los inhibidores mTOR se están utilizando para el tratamiento de anomalías vasculares (AV) complejas sin respuesta a tratamientos convencionales. Presentamos nuestros resultados en pacientes pediátricos tratados con sirolimus. METODOS: Análisis retrospectivo de pacientes tratados con Sirolimus, entre 2014 y 2017, describiendo el tipo de anomalía vascular, respuesta al tratamiento y complicaciones derivadas de su empleo. Se incluyeron pacientes con anomalías vasculares complejas, tras firma del consentimiento informado y con dosis inicial de 0,8 mg/m2/12 horas, monitorizando niveles plasmáticos. Se definió respuesta favorable tanto en términos clínicos como radiológicos. RESULTADOS: Recibieron sirolimus 9 pacientes, mediana de edad de 14 meses (RIQ: 1 mes-14 años). El 66% fueron niñas. Se trataron 5 malformaciones linfáticas (ML) microquísticas complejas (en algunas como coadyuvante a otros tratamientos), 1 linfangioendoteliomatosis multifocal con trombopenia, 1 linfangiomatosis kaposiforme, 1 malformación mixta veno-linfática, 1 hemangioendotelioma kaposiforme (HEK). Mediana de tratamiento: 4 meses (2-18 meses). En 6 pacientes (66%) se objetivó resolución o mejoría de las lesiones. El paciente con HEK mostró resolución completa tras 2 meses de tratamiento. En dos pacientes con ML microquística y en el paciente con malformación mixta, se apreció mejoría clínica y disminución del tamaño de las lesiones tras una mediana de tratamiento de 3 meses. Se apreció efecto rebote en dos ML al suspender el tratamiento. Tres pacientes presentaron hipertransaminasemia e hipercolesterolemia, sin precisar tratamiento médico. CONCLUSIONES: En nuestro estudio, objetivamos que el sirolimus tuvo una eficacia moderada en el tratamiento de AV complejas, pero fue resolutivo en el HEK.

RESUMO

OBJECTIVES: To study the variability of techniques used for vascular access of central venous devices, totally implanted and external tunneled, as well as polling the use of ultrasound by pediatric surgeons in Spain. MATERIAL AND METHODS: Descriptive study of a survey results, conducted by phone, email and online, about 20 items related to the placement of these devices in children and the use of ultrasound in this procedure. RESULTS: We analyzed 71 surveys from 31 national hospitals. The response rate was 54%. In 66% of the cases the pediatric surgeon is the one who carries out the vascular access. 75% of the respondents place less than 25 catheters/year. Only 28% have attended to an ultrasound-guided vascular puncture course. The vein used more often is the internal jugular (55%), followed by the subclavian (17.4%), with preference for the right side in most of the cases (87%). 64% perform the ultrasound-guided technique, 29% the venous cutdown and 7% the landmark approach. There is no significant association between the technique chosen (landmark vs ultrasound-guided) and the vein used (p= 0,062). The majority of the respondents does not modify the usual approach in case of coagulopathy. We describe the complications associated with the three techniques. CONCLUSIONS: The preferred via for the vascular access by pediatric surgeons is the internal jugular vein, being this access ultrasound-guided in most of the cases. 91.5% consider the use of ultrasound decreases the number of associated complications. Nevertheless, just a minority has attended to a training course.


OBJETIVOS: Estudiar la variabilidad de técnicas en el acceso vascular de catéteres intravenosos centrales totalmente implantados y tunelizados externos, así como indagar sobre la utilización de la ecografía por parte de los cirujanos pediátricos en España. MATERIAL Y METODOS: Estudio descriptivo de los resultados de una encuesta realizada por vía telefónica, correo electrónico y on-line, acerca de 20 ítems relacionados con la colocación de estos dispositivos en niños y el uso de la ecografía. RESULTADOS: Se analizaron 71 encuestas de 31 hospitales españoles. La tasa de respuesta fue del 54%. En el 66% de los casos es el cirujano el que realiza el acceso vascular. El 75% de los encuestados coloca menos de 25 catéteres/año. Solo el 28% realizó algún curso de punción ecoguiada. La vena más utilizada es la yugular interna (55%), seguida de la subclavia (17,4%), prefiriendo la mayoría el lado derecho (87%). Un 64% realiza punción ecoguiada, un 29% venotomía y un 7% punción por referencias anatómicas, sin asociación significativa entre la técnica de punción elegida (referencias anatómicas vs ecoguiada) y la vena utilizada (p= 0,062). La mayoría no modifica la técnica habitual ante la presencia de coagulopatía. Se describen las complicaciones asociadas a las tres técnicas. CONCLUSIONES: La vía preferida por los cirujanos pediátricos encuestados para el acceso vascular es la vena yugular interna, siendo ecoguiado en la mayoría de los casos. Un 91,5% opina que la ecografía disminuye el número de complicaciones asociadas, sin embargo solo una minoría ha realizado algún curso de formación.

RESUMO

OBJETIVES: The implantation of long duration intravenous catheters in pediatric population constitutes a challenge due to the size of vascular structures. Because of that, ultrasound is an important tool for vascular accesses in newborns and infants. The objective is to analyze our experience in ultrasound-guided implantation of reservoir type and tunneled catheters, as well as to compare it between both age groups. MATERIAL AND METHODS: Review of the ultrasound-guided implantable catheters placed from October 2010 to December 2014 in children under 18 months. RESULTS: 32 devices were placed in 4 neonates and 28 infants. Mean age was of 252 days and mean weight of 6,7 kg. 23 of them were reservoir type devices and 9 tunneled. No statistically significant differences were found for mean surgical time (55 versus 52 minutes). In tunneled catheters implantation there was no difference in surgical time between neonates and infants, but there was difference for reservoir type catheters (72 minutes in neonates vs 53 minutes in infants). In 78,5% of infants it was possible to place the catheter in the first puncture, versus 50% of neonates, although it was not statistically significant. As complications, one hematoma and one postoperative infection were described. CONCLUSIONS: We found that implantation of reservoir type catheters in infants constituted less surgical time compared with neonates, and puncture on left axillary vein was the most effective. Axillary vein ultrasound-guided approach is a safe and reproducible procedure that needs a process of formation and training.


OBJETIVOS: La colocación de catéteres intravenosos de larga duración en Pediatría constituye un reto debido al tamaño de las estructuras vasculares. Por ello, la ecografía es una herramienta importante para los accesos vasculares en recién nacidos y lactantes. El objetivo es analizar nuestra experiencia en la colocación guiada por ecografía de los catéteres tipo reservorio y tunelizados así como compararla en estos dos grupos etarios. MATERIAL Y METODOS: Revisión de los catéteres colocados mediante punción ecoguiada desde octubre de 2010 a diciembre de 2014 en niños menores de 18 meses. RESULTADOS: Se colocaron 32 dispositivos en 4 neonatos y 28 lactantes. La media de edad fue 252 días y el peso medio, 6,7 kg. 23 fueron dispositivos tipo reservorio y 9 tunelizados. No se encontraron diferencias estadísticamente significativas para el tiempo quirúrgico medio empleado en ambos dispositivos (55 vs 52 minutos). En la colocación de catéteres tunelizados no hubo diferencia en el tiempo quirúrgico entre neonatos y lactantes, pero sí para los reservorios (72 minutos en neonatos vs 53 minutos en lactantes). En el 78,5% de los lactantes se logró canalizar en el primer intento frente al 50% en los neonatos, aunque esto no fue estadísticamente significativo. Como complicaciones se describieron un hematoma y una infección postoperatoria. CONCLUSIONES: Encontramos que la colocación de reservorios en lactantes supuso un menor tiempo quirúrgico comparado con los neonatos, y la punción sobre vena axilar izquierda fue más efectiva. El abordaje ecoguiado de la vena axilar es un procedimiento seguro y reproducible, que requiere un proceso de formación y entrenamiento.

RESUMO

OBJECTIVES: To describe our experience in testicular and paratesticular tumors during the prepubertal stage, focusing especially on its character of benignity/malignancy and surgical treatment used. MATERIAL AND METHODS: Retrospective review of all testicular tumors in children under 12 years diagnosed and treated in our clinical setting from 1998-2015. Data on their presentation, study and management were collected. RESULTS: 17 children with prepubertal testicular tumors were identified. The clinical presentation as palpable testicular mass occurred in 12 cases (70.5%). Levels of tumor markers (alpha-fetoprotein and ßhCG) were only increased alpha-fetoprotein in two cases. In the histopathological study, 64.7% of the tumors were benign (five mature teratomas, four Leydig cells tumors, one immature teratoma and one sexual cords-stromal tumor). Malignant tumors were three rhabdomyosarcoma (17.6%), two yolk-sac tumors (11.8%) and one Burkitt lymphoma (5.9%). The mean age of benign was 5.9 years old and malignant 2.9 years old (p=0.68). From neoplastic lesions nine were non-germline (53%) and eight germline (47%). In the management testis-sparing surgery was performed in six benign tumors, and orchiectomy in five benign tumors and in all malignant tumors except lymphoma which received chemotherapy. CONCLUSIONS: Benign primary testicular and paratesticular tumors are more frequent in prepubertals and testis-sparing surgery is indicated by inguinal approach.


OBJETIVOS: Describir nuestra experiencia en tumores testiculares y paratesticulares en la etapa prepuberal, incidiendo sobre todo en su carácter de benignidad/malignidad y el tratamiento quirúrgico empleado. MATERIAL Y METODOS: Revisión retrospectiva de todos los tumores testiculares en menores de 12 años, diagnosticados y tratados en nuestro ámbito clínico desde 1998 hasta 2015. Se recogieron datos sobre su forma de presentación, estudio y manejo. RESULTADOS: 17 niños con tumores testiculares prepuberales fueron identificados. La presentación clínica como masa palpable testicular se dio en 12 casos (70,5%). De los niveles de marcadores tumorales (alfa-fetoproteína y ßhCG), solo estuvo aumentada la alfa-fetoproteína en dos casos. En el estudio anatomopatológico, el 64,7% de los tumores fueron benignos (cinco teratomas maduros, cuatro tumores de células de Leydig, un teratoma inmaduro y un tumor de los cordones sexuales-estromal). Los tumores malignos fueron tres rabdomiosarcomas (17,6%), dos tumores del saco vitelino (11,8%) y un linfoma de Burkitt (5,9%). La edad media de los benignos fue 5,9 años y de los malignos 2,9 años, (p=0,68). De las lesiones neoplásicas nueve fueron de estirpe no germinal (53%) y ocho germinales (47%). En el manejo quirúrgico se realizó tumorectomía en seis tumores benignos, orquidectomía en cinco tumores benignos y en todos los tumores malignos salvo el linfoma que sólo recibió quimioterapia. CONCLUSIONES: Los tumores testiculares y paratesticulares primarios benignos son más frecuentes en la etapa prepuberal y en su tratamiento se acepta indicar cirugía conservadora por vía inguinal.

RESUMO

INTRODUCTION: Segmental cervico facial hemangiomas are defined as those longer than 5 cm, affecting a specific facial area. These lesions can be eventually associated with the PHACE syndrome. Our aim is to propose neonatal treatment with propranolol, showing its efficacy/safety, given the scarce evidence on its neonatal use. CLINICAL OBSERVATION: After written informed consent, four patients with segmental facial hemangioma were treated with propranolol in the neonatal period. Adverse effects were registered during initial admission. Three of the four patients had PHACE syndrome. Propranolol was effective in 100% of patients, showing hemangioma´s involution without any adverse effect. COMMENTS: In our series, propranolol was effective and showed no side effects in the neonatal period. If propranolol benefits are greater than its risks, administration of the lowest effective dose is recommended, under hospital surveillance, starting shortly after diagnosis, in order to achieve improved efficacy.


INTRODUCCION: Los hemangiomas cérvico-faciales son considerados segmentarios cuando afectan a un área específica de la cara y miden más de 5 cm y, en ocasiones, forman parte del síndrome de PHACE. Nuestro objetivo es proponer el tratamiento de dichos hemangiomas con propranolol en etapa neonatal, mostrando su eficacia/seguridad dado que existe poca evidencia al respecto. OBSERVACION CLINICA: Revisamos 4 pacientes diagnosticados de hemangioma segmentario facial. Los neonatos fueron tratados de forma hospitalaria inicial con propranolol, tras firma de consentimiento informado, y fueron ingresados para control de aparición de complicaciones. Tres de los cuatro casos clínicos fueron diagnosticados de síndrome de PHACE. El propranolol fue efectivo en el 100% de los pacientes, demostrando involución de los hemangiomas. COMENTARIOS: En nuestra serie el propranolol fue eficaz sin evidenciar complicaciones en el período neonatal. Si los beneficios del propranolol sobrepasan los riesgos, se recomienda administrar la menor dosis eficaz, de forma hospitalaria y precoz para obtener mejores resultados.

RESUMO

OBJECTIVES: Surgical site infection (SSI) has a considerable impact on neonatal morbidity. There are known risk factors such type of surgery (clean/contaminated), prematurity, surgical length, hypoalbuminemia, previous infection, prolonged mechanical ventilation, and so on. Many perioperative factors have not been studied, opposite to adults. We have developed a survey on intraoperative attitudes and measures, as surgical wound management in Neonates among pediatric surgeons, to seek for a wider consense. METHODS: Multi-response survey with 22 items, based on the Surgical Infection Society NIH 2008 clinical guideline. Each item poses a question on perioperative attitudes, surgical aspects and wound management. Each question is subdivided in two categories, depending on urgency and type of surgery (clean/contaminated). RESULTS: 159 surveys were sent. Among those, we received back 51 (32%). 69% of the interviewed surgeons use clorhexidin to prepare surgical field, 25% use Iodine solutions. 69% never use diathermy to incise skin. There was no agreement on the use of sterile plastic adhesive drapes, intra-cavity lavage, changing surgical gloves/material, or wound irrigation during closure. 82% never use cyanocrilate dressing. Intracuticular skin suture and simple stitches were used indistinctly. Wound management and dressings were not uniform and depended on each pediatric unit. CONCLUSIONS: The survey reflects the lack of consensus regarding prophylactic measures and wound management among pediatric surgeons who care after surgical neonates.


OBJETIVOS: La infección de herida quirúrgica (IHQ) es una causa frecuente de morbimortalidad en Neonatología. Existen factores de riesgo conocidos: tipo de cirugía (sucia/contaminada/limpia), prematuridad, duración de intervención, hipoalbuminemia, infección previa, ventilación mecánica prolongada y contaminación de vía central. Otros factores perioperatorios no han sido estudiados en neonatos, sí en adultos. Desarrollamos una encuesta sobre las actitudes y las medidas, intraoperatorias y de manejo de herida. Pretendemos dilucidar si existe consenso sobre la profilaxis de IHQ neonatal. METODOS: Encuesta con 22 ítems, basada en la guía de prevención de la IHQ en adultos (Surgical Infection Society, 2008). Cada ítem cuestiona temas sobre hábitos perioperatorios, intra y postoperatorios, relacionados con el manejo de la herida quirúrgica en el neonato, y consta de dos preguntas, según sea cirugía sucia/urgente o limpia/contaminada. Las opciones de respuesta son 4: siempre, con frecuencia, raramente y nunca. Enviamos la encuesta a cirujanos pediátricos españoles mediante correo electrónico en el primer trimestre del 2012. RESULTADOS: Se enviaron 159 encuestas. 51 (32%) respondieron. 69% emplean clorhexidina para preparar campo, 25% usan povidona iodada. Solo el 51% refirió dejar actuar siempre un minuto el antiséptico. 69% nunca usan bisturí eléctrico en piel para ampliar herida. No hubo respuestas unánimes en cuanto al uso de paños adhesivos protectores del campo, la irrigación de planos con suero o antisépticos durante el cierre, el empleo de drenajes, cambio de guantes y/o material al iniciar el cierre (cirugía sucia). El 72% y el 82% nunca emplean cianocrilato como cierre o apósito en neonatos, respectivamente. En cirugía sucia, 43% suturan piel con intradérmica y 49% con puntos sueltos. CONCLUSIONES: La distribución de respuestas refleja la falta de consenso sobre los aspectos de la técnica quirúrgica y el manejo perioperatorio que podrían estar relacionados con la profilaxis de IHQ neonatal.

RESUMO

UNLABELLED: There is controversy about the convenience of performing a bacteriological peritoneal culture in pediatric appendicitis. We performed a sero-epidemiological survey of the bacteria found in peritoneal swabs from pediatric appendicitis operated in our hospital. METHODS: Ambispective study. Retrospective revision of the bacteriological results from peritoneal swabs performed in pediatric appendicitis from january 2009 to december 2010 (2 years) and prospective study of peritoneal swabs collected between january 2011 and december 2011 (one year). RESULTS: We found 728 pediatric patients (mean age 7.1, range: 2-11 years). Among these, 108 were < 5 years. Cultures were performed in 328 (45.1%). A positive result was found in 155 swabs, (47.3%). Positive cultures were more frequent in patients < 5 years (69.2% vs 40.4%, p < 0.001). The most frequent pathogens were E. coli: 122 specimens, Streptococcus spp (50 swabs), P. aeruginosa: (45) and B.fragilis: (35) Younger age was strongly associated with P. aeruginosa: (30.8% vs 8.4%, p < 0.001. OR: 4.8. IC 95%: 2.3-9.8). So was the detection of E. coli (50% vs 33.2% p = 0.01). 21.3% (26 swabs) of E. coli were resistant to amoxicillin-clavulanic acid. There were 15 (12.3%) multiresistant (ESBL) E. coli. Among the Streptococcus, 32% (16 out of 50) were resistant to clindamicin, and so were 28.6% of the B. fragilis (10 out of 35). DISCUSSION: . The most frequent pathogens were E. coli, Streptococcus spp and P. aeruginosa. P. aeruginosa is five times more frequent in patients < 5 years. Resistance of E. coli to amoxiclavulanate was high: 21.3% of the specimens. We found that 12.3% of the E. coli produced ESBL.

RESUMO

INTRODUCTION: Wilms' tumor (WT) is the most frequent renal tumor in childhood. Therapeutic management progression has increased survival rates, and as a result, long-term adverse effects. MATERIALS AND METHODS: A descriptive retrospective study of a case series from 1977 to 2023 was carried out. The characteristics of the treatments received and the adverse effects listed on medical records were analyzed via phone surveys. RESULTS: 50 patients (25 boys-25 girls) with a mean age of 3.6 years (3 months-11 years) at diagnosis were included. Most of them (94%) were treated according to the protocol established by the European standards of pediatric oncology, which are characterized by the use of neoadjuvant chemotherapy. In one patient, the American treatment scheme was followed. The most common drugs used were vincristine and actinomycin D (78%). Only 12 patients (28%) received anthracyclines. Unilateral nephrectomy was the most frequent surgical technique (84%). Renal disorders were the most common (46%). However, the occurrence of second neoplasias (9%) and reproductive disorders (8% between boys and girls) had a greater impact on patients' quality of life. Multiple - cardiac (23%), endocrine (26%), and pulmonary (15%) - disorders associated with the treatments received were reported. CONCLUSIONS: WT treatment has an impact on health. Adequate and rigorous surgery, close follow-up, and limiting chemotherapy doses and radiation exposure can minimize long-term sequels.


INTRODUCCION: El tumor de Wilms (TW) es el tumor renal más frecuente en la infancia. La evolución del manejo terapéutico ha incrementado la tasa de supervivencia y como consecuencia, los efectos secundarios a largo plazo. MATERIAL Y METODOS: Realizamos un estudio retrospectivo descriptivo a partir de una serie de casos entre 1977 y 2023. Estudiamos las características de los tratamientos recibidos y los efectos secundarios que constan en su historia clínica y a través de cuestionarios telefónicos. RESULTADOS: Localizamos 50 pacientes (25 hombres-25 mujeres) con edad media al diagnóstico de 3,6 años (3 meses-11 años). La mayoría fueron tratados según protocolo vigente de las guías europeas de oncología pediátrica (94%) caracterizadas por el uso de quimioterapia neoadyuvante. En un paciente Se siguió el esquema americano de tratamiento. Los fármacos más utilizados fueron vincristina y actinomicina D (78%); solo 12 pacientes (28%) recibieron antraciclinas. La nefrectomía unilateral fue la técnica quirúrgica más empleada (84%). Las alteraciones renales fueron las más frecuentes (46%). Sin embargo, la aparición de segundas neoplasias (9%) y aquellas alteraciones relacionadas con la reproducción (8% entre hombres y mujeres) suponen un mayor impacto en la calidad de vida de los pacientes. Se describen múltiples alteraciones: cardíacas (23%), endocrinas (26%) o pulmonares (15%) relacionadas con los tratamientos recibidos. CONCLUSIONES: El tratamiento del TW afecta a la salud general. Una cirugía adecuada y rigurosa, limitar las dosis de quimioterapia, minimizar la exposición a la radiación y un seguimiento estrecho puede minimizar las secuelas a largo plazo.

RESUMO

We report on a 6-year old child with a penile injury resulting in the inclusion of a pellet in the cavernous body, by a fortuitous shot. Conservative approach with elective extraction of the bullet and cavernous body repair led to a satisfactory result, in better anatomic conditions. The patient did not have any perioperative complication. Accidents by air weapons are particularly important in children, because these weapons are erroneously considered as toys. Air gun injuries to head, neck and thorax have been often published, but these injuries are rare in the chidren genitourinary area.

RESUMO

The management of intra-abdominal testis can be challenging, as evidenced by the multiple methods suggested for its assessment and treatment. In this paper, we report our long-term results for our 14-year surgical experience with laparoscopic management. Methods. Retrospective study of laparoscopic interventions performed at our department for nonpalpable testes between 1996 and 2009. In 174 procedures, we found 72 intra-abdominal testes (5 bilateral) and 25 direct orchiopexies (3 bilateral) were performed. One-stage Fowler-Stephens orchiopexies (FSO) were performed in 5 children. 40 boys underwent the two-stage FSO technique (2 bilateral) in those that reached the contralateral inguinal ring. The second stage was performed in 4 cases with a laparoscopic approach, the rest of them underwent an inguinal procedure exclusively. Mean age for the first intervention was 3.7 yrs, and the second stage was performed on average after 10.9 months. Of 42 undescended testes, 22 were on the right side and 20 on the left side. Median followup was 24 months. Results. Of 42 two-stage FSOs performed, 27 surgeries were very successful, with a testis size equivalent to the contralateral mate; 7 had good results, with a smaller testis (volume up to 50% of contralateral); and 7 resulted in atrophic testis. No complications were encountered during surgery. Conclusions. There is no doubt about the usefulness of laparoscopy for intra-abdominal testes with short spermatic vessels, and the two-stage Fowler-Stephens technique should be the procedure of choice given its high success rate.

RESUMO

We report the case of an 18-month-old boy who presented with caries in the upper central incisors associated with the use of propranolol solution for the treatment of an infantile hemangioma. This side effect of propranolol solution has not been reported before, and it may result from a sucrose-based excipient of the solution, or decreased salivation caused by beta-adrenergic antagonist effect of propranolol.

RESUMO

OBJETIVE: To evaluate long-term renal function and morbimortality in non-syndromic Wilms tumor (WT) survivors. METHODS: Retrospective study about WT patients treated in 1993-2017, according to SIOP protocols. Mortality, glomerular filtration rate (GFR), prevalence of hypertension and requirement of dialysis and renal transplant were evaluated. Chronic kidney disease (CKD) was defined as GFR <90 ml/min/1.73 m2. RESULTS: Thirty-nine children were treated in the 25 analyzed years. Median time of follow-up was 6 years (0.5-21 years). 48% (19 patients) debuted with stage I or II. Four cases had high-grade histo-logy. Mortality rate was 10%. GFR data were found in 37 patients. Chronic kidney disease (grade I-II) turned up in 6 patients (16%). No patient required renal replacement therapy or renal transplant. 16% of patients developed CKD in both unilateral and bilateral WT, (p>0.05); OR 1.04 (IC 95% 0.09-10.9). Identical results were obtained comparing patients treated with or without radiotherapy (16%). Children with stage I-III had CKD in 11% vs. 40% of patients with stage IV (p=0.12); OR 5.3 (IC 95% 0.61-45). None of them presented hypertension in addition. CONCLUSIONS: In the current study the prevalence of CKD was low but not negligible, although no patients required renal replacement therapy or renal transplant. Bilateral renal involvement and radiotherapy were not associated with CKD development. Metastatic disease determines a higher risk of CKD.


OBJETIVOS: Evaluar la función renal y la morbimortalidad a largo plazo, en supervivientes de tumor de Wilms (TW) no sindrómico. MATERIAL Y METODOS: Estudio retrospectivo de pacientes con TW entre 1993-2017 tratados según protocolos SIOP. Evaluamos mortalidad, filtrado glomerular (FG), prevalencia de hipertensión arterial (HTA), necesidad de diálisis y trasplante renal. Se definió enfermedad renal crónica (ERC) como FG <90 ml/min/1,73 m2. RESULTADOS: En los 25 años analizados se trataron 39 pacientes con edad media diagnóstica de 3,6 años (0,3-11 años). Mediana de seguimiento 6 años (0,5-21 años). El 48% (19 pacientes) debutaron con estadio I o II. Cuatro pacientes presentaron histología de alto riesgo (10%). La mortalidad fue del 10%. El 16% (6 pacientes) desarrolló ERC (grados I-II). Ningún paciente precisó terapia renal sustitutoria (TRS) o trasplante. La presencia de ERC tanto en enfermedad unilateral como bilateral fue del 16%, p>0,05; OR 1,04 (IC 95% 0,09-10,9). Se obtuvieron idénticos resultados (16%) comparando pacientes que recibieron radioterapia frente a aquellos que no. Los pacientes en estadio I, II y III presentaron una prevalencia de ERC del 11% vs. 40% en estadio IV (p=0,12); OR 5,3 (IC 95% 0,61-45). Ningún paciente asoció HTA crónica. CONCLUSIONES: En el presente estudio la prevalencia de ERC en supervivientes de TW no sindrómico es baja pero no desdeñable, aunque ninguno precisó trasplante renal o TRS. La presencia de enfermedad bilateral y la radioterapia no se asociaron al desarrollo de ERC. La enfermedad metastásica condiciona un riesgo mayor de ERC.
