ABSTRACT

BACKGROUND: Survival of children with pineal region tumors has increased significantly in the last decade; these tumors have an insidious outcome associated with endocrine disorders with high morbidity and mortality, especially after gross resection. The objective was to report the survival, outcome, morbidity and mortality according to type of surgery, histology and treatment in children with pineal region tumors. METHODS: This retrospective study included all patients of 17 years or less with diagnosis of pineal region tumor, who went over a period of 10 years to a children's hospital. A histopathological review was made, and the extent of resection was determined. The survival was also estimated. RESULTS: Forty-six patients were included, out of which 36 had complete medical records and adequate pathologic material. Gross resection was performed in 24 (66.6 %), and biopsy in 12 (33.3 %); 23 (88 %) patients died; hydroelectrolytic imbalance was the cause of 14 deaths (60 %) and the other nine (39.1 %) were secondary to tumor progression. Ten-years survivals among patients treated with gross resection and biopsy were 52 and 75 %, respectively (p = 0.7). Endocrine alterations were observed in 13 patients (36.1 %); in 10 of these (76.9 %) the total resection was performed. CONCLUSIONS: Pineal region tumors in children can be treated with diagnostic biopsy, followed by adjuvant treatment consisting of chemotherapy and radiotherapy.


Introducción: la supervivencia de los niños con tumores de la región pineal se ha incrementado en la última década; estos tienen una evolución insidiosa asociada con los desórdenes endocrinológicos y una alta morbilidad y mortalidad, sobre todo después de la resección. El objetivo es reportar la supervivencia, la morbilidad y mortalidad según el tipo de cirugía, la histología y el tratamiento en un grupo de niños con tumores de la región pineal. Métodos: estudio retrospectivo que incluyó a todos los pacientes con diagnóstico de tumor de la región pineal menores de 17 años de edad que acudieron en un periodo de 10 años a un hospital de pediatría. Se realizó una revisión histopatológica, se determinó la extensión de la resección y se estimó la supervivencia. Resultados: se incluyeron 46 pacientes, 36 de los cuales tenían expediente completo y material de patología adecuado. La resección total se realizó en 24 (66.6 %) y biopsia en 12 (33.3 %); fallecieron 23 pacientes (88 %) y fue el desequilibrio hidroelectrolítico la causa de 14 defunciones (60 %) y la progresión tumoral la causa de las 9 defunciones restantes (39.1 %). La sobrevida a 10 años de los pacientes tratados con resección total y biopsia fue del 52 y 75 %, respectivamente, con una p = 0.7; se presentaron alteraciones endocrinológicas en 13 (36.1%) pacientes de los cuales a 10 (76.9 %) se les realizó la resección de la tumoración. Conclusión: los tumores de la región pineal en niños se pueden tratar con biopsia diagnóstica seguida de tratamiento adyuvante con quimioterapia y radioterapia.

ABSTRACT

PURPOSE: To determine the role of RPLND for residual masses following chemotherapy in patients with non-seminomatous germ cell tumors (NSGCT) stage T1N2 and T1N3 (IIB and IIC). MATERIALS AND METHODS: We have preformed retrospective analysis of 11 patients who underwent RPLND for residual masses following chemotherapy in an oncologic reference center between January 1997 and December 2002. All patients harbored either pure nonseminomatous or mixed tumors in the testis tissue and had undergone 4 cycles of primary chemotherapy with bleomycin, etoposide and cisplatin. The residual masses were assessed by abdominal computed tomography preoperatively. RESULTS: There were perioperative complications in 3 cases owing to vascular iatrogenic lesion. One of who died in the early postoperative period due to extensive iliac thrombosis. The other 2 patients had an inferior vena cava injury owing to the difficulty in removing the attached lymph nodes. The injuries were repaired by continuous suture with Prolene 5-0. All patients had tumors in the final pathological report and were referred to other 2 cycles of chemotherapy with the same drugs. Seven patients (63.3%) had complete response and remained free of the disease in a mean follow up of 38.3 months (ranging from 12 to 72). The remaining 3 patients had disease progression, 2 of which died 6 and 12 months after surgery, respectively, and one patient missed the follow-up after salvage chemotherapy. CONCLUSION: Retroperitoneal lymph node dissection for residual masses after chemotherapy is a high-morbidity procedure, even by experienced surgeons, although it remains an efficient modality of treatment in advanced germ cell carcinoma. The high frequency of tumor found in the RPLFN following chemotherapy might have been caused by the small number of patients in this study.

ABSTRACT

OBJECTIVE: The present study aims to report the preliminary experience with videolaparoscopic retroperitoneal lymphadenectomy in the treatment of patients with non-seminomatous testicular tumor. MATERIALS AND METHODS: Seven surgeries were performed in order to access retroperitoneal lymph nodes in patients with non-seminomatous testicular cancer. We performed the videolaparoscopic retroperitoneal lymphadenectomy (LRL) technique in 5 patients with stage I disease and laparoscopic resection of residual mass (LRRM), following chemotherapy (ChT), in 2 patients with stage II disease. Initial approach was obtained through 4 trocars, using an incision in supra-umbilical midline when manual assistance was required. Surgical time was analyzed, as well as blood loss, need for analgesic drugs postoperatively, hospital stay, complications, need for blood transfusion, histopathological data and tumor control in a mean follow-up of 18 months. RESULTS: Mean surgical time was 200 to 260 minutes in LRL and LRRM groups respectively, mean blood loss was 300 mL for the LRL group and 400 mL for the LRRM group, without need for transfusions. There was a lesion in the vena cava in the LRL group, which was managed with manual assistance and one conversion in the LRRM group, due to a 10-cm tumor mass that was adhered to the aorta. Mean hospital stay was 3 days, excluding the converted case, and the use of analgesic drugs was needed until the second postoperative day. Of the stage I patients, 2 had active disease in retroperitoneum, and underwent adjuvant ChT. The 2 residual masses were teratomas. There was no recurrence during the follow-up period. CONCLUSIONS: Videolaparoscopic retroperitoneal lymphadenectomy is a procedure with high technical complexity and a higher potential for conversion when performed following chemotherapy.

ABSTRACT

Los pacientes con tumores germinales no seminomatosos presentan metástasis encefálicas en 8 por ciento a 15 por ciento de los casos, generalmente en el contexto de una recaída sistémica. Si bien el primer gesto terapéutico ante un secundarismo único suele ser la cirugía, su particular quimiosensibilidad hace planteable la indicación de quimioterapia inicial seguida de radioterapia con o sin cirugía posterior. Al igual que en otros tumores sólidos los pacientes portadores de lesiones múltiples reciben tratamiento sistémico con o sin el agregado de radioterapia. Presentamos 5 pacientes de entre 20 y 43 años portadores de tumores germinales no seminomatosos con secundarismo encefálico que se presenta al momento del diagnóstico en dos casos y en el contexto de una progresión lesional en otros dos. En el caso restante se destaca su diagnóstico cuando se había objetivado una respuesta parcial mayor extraencefálica. El coriocarcinoma y el tumor de saco vitelino son las variedades histológicas más frecuentes en esta serie. 4 de los 5 pacientes pertenecían al grupo de alto riesgo y todos presentaban extenso compromiso pulmonar. En aquellos pacientes portadores de secundarismo único la cirugía cosntituyó el primer gesto terapéutico. Se destaca el beneficio de la combinación de los tratamientos sistémicos y radiante holocraneal en quienes presentaban múltiples lesiones encefálicas. El escaso número de pacientes impide obtener conclusiones con relación a la sobrevida, pero podemos destacar el mal pronóstico que implica el desarrollo de secundarismo encefálico en el contexto de refractariedad al tratamiento sistémico aún cuando sea único, y, por otra parte, la posibilidad de obtener remisiones completas duraderas en un grupo de pacientes seleccionados.

ABSTRACT

Antecedentes: los tumores germinales del mediastino son lesiones de infrecuente presentación. Existe cierta tendencia a explorar los tumores mediastinales operables sin tener en cuenta que determinadas entidades patológicas, entre ellas algunos tumores germinales, tienen indicación inicial de otro tratamiento diferente. Objetivo: relatar la experiencia de los autores en una sola institución asistencial. Comunicar un algoritmo para el estudio y el tratamiento de los tumores germinales primarios de mediastino. Lugar de aplicación: Centro oncológico universitario de asistencia, docencia e investigación. Diseño: retrospectivo. Población: 9 casos. 1 mujer portadora de teratoma maduro, 8 hombres con tumores germinales malignos. Edades entre 18 y 39 años. Se diagnosticaron 3 seminomas, 2 carcinomas embrionarios, 1 tumor se seno endodérmico, 1 teratoma+carcinoma embrionario, un tumor maligno mixto (seminoma+carcinoma embrionario+teratoma inmaduro) y 1 teratoma maduro con esbozos de órganos. La forma de presentación fue dolor esternal en 4 (uno de ellos con taponamiento cardíaco por derrame pericárdico), disnea en 2, disfagia en 1 y adenopatías cervicales asintomáticas en 2. La manifestación radiológica fue tumor circunscripto en el mediastino. El teratoma maduro presentaba calcificaciones. Se operaron 5 enfermos (4 toracotomías y una videotoracoscopía). En 4 se pudo realizar exéresis completa; 1 fue irresecable por invasión de estructuras nobles contiguas. Resultados: la paciente operada por teratoma maduro, se encuentra curada. De los 8 malignos restantes 2 fueron operados inicialmente, sólo 1 fue resecado. Ambos recibieron Qt a pesar de lo cual tuvieron progresión o recaída. 6 tuvieron diagnóstico histológico antes de programar el tratamiento y recibieron quimioterapia (Qt). De éstos últimos, 2 fueron intervenidos con criterio de rescate (CxR) por persistencia de imagen tumoral luego de Qt. La paciente operada por teratoma maduro, se encuentra curada. De los 8 malignos restantes, los 2 operados inicialmente recibieron Qt: 1 de ellos se curó y el otro tuvo progresión lesional. Por efecto de la Qt exclusiva (4 enfermos), 2 se curaron y llevan más de 10 años, 2 progresaron y fallecieron. Los 2 restantes fueron sometidos a cirugía de rescate post Qt, de los cuales uno lleva 5 meses libres de enfermedad y otro falleció diseminado...(AU)

ABSTRACT

Genéricamente, el cáncer de ovario representa enfermedades con comportamientos clínicos distintos. Así, los tumores poco frecuentes de células germinales son tratados con éxito en la gran mayoría de las pacientes, mediante regímenes convencionales de quimioterapia. En contraste, en el cáncer epitelial, que representa el 90 por ciento de los casos, a pesar de que muestra sensibilidad a la quimioterapia, no se ha logrado alcanzar resultados satisfactorios. En la búsqueda de mejores respuestas para el tratamiento de la neoplasia epitelial de ovario, recientemente se han investigado nuevos fármacos como paclitaxel, doxorrubicina liposomal, docetaxel, topotecan, gemcitabina y combinaciones de diferentes drogas, así como tratamientos con base en anticuerpos monoclonales que ofrecen una nueva esperanza. El objetivo de este trabajo es revisar y difundir las tácticas de tratamiento citotóxico disponibles para esta neoplasia.

ABSTRACT

A variety of mass lesions are placed in and around of the sella turcica. Although their common location these lesions have distinguishing features and different approaches can be selected. There are conventional transcranial and sophisticated skull base approaches. We report our experience with a subfrontal route to the sellar region. Between February 1997 and March 1998, 19 tumors placed around the sella have been treated surgically by this method. Eleven of them were pituitary tumors, 3 were craniopharyngeomas, 2 were meningiomas, and 1 was germinoma. Total removal was achieved in 17 cases. There was not operative mortality. Postoperative complications included twelve cases of unilateral anosmia and four cases of transitory diabetes insipidus. Progressive stroke occurred in one patient. These results stress the importance of the subfrontal approach to reach such lesions in sellar region.

ABSTRACT

Os processos expansivos situados ao nível da região selar constituem um variável número de patologias que, apesar da localização semelhante, têm características clínicas, radiológicas, patológicas e origens diferentes. Assim sendo, diferentes tipos de abordagens são utilizados no tratamento cirúrgico destas lesões. Dentre os acessos transcranianos convencionais e os mais sofisticados acessos à base do crânio, o acesso sub-frontal proporciona visão direta das estruturas neurovasculares da região. Este estudo descreve 19 tumores operados por esta via, no período compreendido de fevereiro de 1997 a março de 1998. Onze destas lesões eram adenomas pituitários, 3 eram craniofaringiomas, 2 eram meningiomas, 1 germinoma e 1 lesão inflamatória do nervo óptico. A remoção total dos tumores foi conseguida em 17 casos. Não houve mortalidade operatória e as complicações mais comuns foram: anosmia unilateral, que ocorreu em 12 casos; diabetes insipidus transitório, que acometeu 4 pacientes; e déficit isquêmico progressivo, que ocorreu em 1 paciente. Estes resultados demonstram que a via sub-frontal é uma opção segura para a cirurgia dos tumores desta região.

ABSTRACT

OBJECTIVE: To study the results of surgical treatment of pulmonary metastases in our department. PATIENTS AND METHODS: We retrospectively studied 44 patients undergoing surgery between 1986 and 1999 for complete resection of pulmonary metastases. Primary tumors had been eradicated, no metastasis to other organs was evident, and functional respiratory capacity was adequate. The patients were assigned to different prognostic groups based on the criteria of the International Registry of Lung Metastases. RESULTS: Forty-eight operations were performed on the 44 patients (21 men and 23 women) whose mean age was 58 years (31-74 years). The most frequent type of primary tumor was epithelial (82%); other types in order of frequency were sarcoma (9%), thyroid gland (4.4%), germ cell (2.2%) and melanoma (2.2%). The mean disease-free interval was 37.7 months (0.168) and the median was 30 months. A single site of metastasis was seen in 66.7% of the cases whereas 33.3% had multiple metastases (17.9% of them bilateral). Posterolateral thoracotomy was the surgical approach in over half the cases (66.7%). We performed wedge resections in 86.6% and lobectomies in 11.1%. Perioperative mortality was 4.4%. Mean survival was 70 months, with 87% alive at one year and 29% at 10 years. For group I (resectable, no risk factors; n = 13) survival was 100% at one year and 75% at 10 years. For group II (resectable, one risk factor; n = 16) the actuarial survival was 78% at one year and 12% at 10 years. For group III (resectable, two risk factors; n = 8), survival was 87% at one year, 62% at three years, 15% at four years and 0% at five years (Log-rank chi 2 9.8 [df = 2)], p = 0.0097). CONCLUSIONS: Surgical resection of pulmonary metastasis is a treatment and diagnostic procedure associated with low mortality and good survival. Prognostic grouping that takes into account number of metastases, disease-free interval and resectability correlates significantly with expected survival regardless of histological typing of the primary tumor.

ABSTRACT

A 27-year-old male, who underwent excision and radiotherapy for a pineal gland germinoma four years previously, subsequently developed panhypopituitarism and, thus, complete azoospermia. Gonadotrophin replacement therapy resulted in the production of a small number of motile spermatozoa which were used for Intracytoplasmic Sperm Injection (ICSI) into oocytes obtained from his wife. After successful fertilization and embryo transfer, a singleton intrauterine pregnancy was achieved which resulted in the normal delivery of a morphologically normal male live infant at term.

ABSTRACT

From March 1980 to December 1995, at the Department of Neurosurgery of the Instituto Nacional de Pediatría (INP), 23 patients were treated for orbital tumors. In this communication, the authors report on the clinical presentation, age, radiological findings, visual-evoked potentials, type of surgery, histological diagnosis, and results. Two kinds of surgical techniques were employed: craniotomy with orbital roof removal (NAFZIGER) and fronto-orbitotomy. Eleven patients had optic nerve gliomas, 3 had fibrous osseous dysplasia, 2 meningiomas, neurofibromas, Langerhans cells histiocytosis, and 1 case of Anaplastic astrocytoma, Teratoma, primitive Neuroectodermal tumor, germinoma with areas of choriocarcinoma. The results were evaluated for the quality of life in regard to the Karnofsky scale, tumor recurrence and postoperative visual-evoked potentials. It is important to note the very variable histological kinds of lesions found in this series that can be approached surgically with cranio orbitotomy with good results.

ABSTRACT

Objetivo: en un estudio retrospectivo, evaluar la extensión del vaciamiento ganglionar retroperitoneal (VGRP) y de la resección tumoral a otros niveles; así como el resultado de la histología de dicha cirugía, en pacientes tratados por tumores germinales testiculares y retroperitoneales. Material y método: se revisaron las historias clínicas de 64 pacientes con diagnóstico de tumor germinal testicular y retroperitoneal, que recibieron VGRP. El VGRP fue clasificado en cuatro grupos: 1) estadificador; 2) posquimioterapia de primera línea; 3) posquimioterapia de segunda línea y 4) cirugía de rescate. Asimismo clasificamos el VGRP según la extensión ganglionar en: bilateral, bilateral modificado, unilateral modificado derecho o izquierdo, extendido o no a la región suprahiliar, interilíaca, así como a otros sitios extraganglionares. Finalmente analizamos el resultado de la histología del VGRP en tres grupos principales: fibrosis/necrosis, teratoma, tumor maligno viable. Resultados: 62 pacientes fueron tratados por un tumor de primitivo testicular, correspondiendo 33 (53 por ciento) a testículo derecho y 29 (47 por ciento) a testículo izquierdo. Cuarenta y uno (66 por ciento) correspondieron a un tumor germinal no seminomatoso (TGNS), 17 (27,5 por ciento) a seminoma y 4 (6,5 por ciento) TGNS más seminoma. Tres pacientes (5 por ciento) desarrollaron un segundo tumor de testículo. Dos pacientes fueron tratados por un tumor germinal primitivo retroperitoneal. En el grupo de pacientes con tumor primitivo testicular, se efectuaron 69 VGRP y dos en el grupo con tumor primitivo retroperitoneal. En el grupo principal de pacientes, fue efectuado un VGRP estadificador nueve veces (13 por ciento), mostrando histología correspondiente a carcinoma embrionario en cuatro. Se realizaron 50 (72,5 por ciento) VGRP posquimioterapia de primera línea, 27 (54 por ciento) por tumor de testículo derecho y 23 (46 por ciento) izquierdo. La extensión del VGRP en estos fue: bilateral 6 por ciento, bilateral más suprahiliar 10 por ciento, bilateral modificado 32 por ciento, bilateral modificado más suprahiliar 6 por ciento, unilateral derecho incompleto 12 por ciento, unilateral modificado izquierdo más suprahiliar 6 por ciento, unilateral izquierdo incompleto 24 por ciento, otros 4 por ciento. En 14 pacientes (28 por ciento) incluyó resección a otros niveles: hígado, pulmón, riñón, etcetera...(AU)

ABSTRACT

OBJECTIVE: To describe the clinical and ethiologic findings of children with Parinaud's syndrome. MATERIAL AND METHODS: 11 children fulfilling the clinical criteria for Parinaud's syndrome were studied. The mean age was 10 years with a range of 10 months to 14 years. RESULTS: Seven cases were tumors (pineal germinoma in four and one each with teratoma, astrocytoma, and an undefined tumor); the remaining 4 cases corresponded to arachnoid cyst in the III ventricule, cysticercosis, tuberculoma and multiple sclerosis. The main treatment was surgical including ventriculoperitoneal shunt because of hydrocephalous secondary to mechanical obstruction. Chemotherapy and radiotherapy were also used for the tumor cases, and steroids for the multiple sclerosis patient. CONCLUSIONS: In contrast to adults, Parinaud's syndrome in our children was associated with a mass, mainly tumoral, which interrupted the afferent and efferent connections of the midbrain structures, such as posterior commissure, riMLF or the interstitial nucleus of Cajal.

ABSTRACT

De marzo de 1980 a diciembre de 1995 se trataron 23 pacientes con tumores orbitarios en el Departamento de Neurocirugía del Instituto Nacional de Pediatría (INP). En este trabajo se analiza edad, características clínicas, alteraciones radiológicas y de potenciales evocados; tipo de cirugía, diagnóstico histopatológico y resultados. En todos ellos se efectuó un abordaje craneoorbitario, tipo destechamiento simple, o bién, por fronto-orbitotomía. De estos pacientes, 11 tenían glioma del nervio óptico, tres displasia ósea fibrosa, dos meningioma, neurofibroma, histocitosis de células de Languerhans; uno astrocitoma anaplásico, teratoma, tumor neuroectodérmico primitivo y germinoma con áreas de coriocarcinoma. Se realizó, craneotomía con destechamiento orbitario (Nafziger) en 19 casos y fronto-orbitotomía en 4. Los resultados fueron clasificados de acuerdo a la escala de karnofsky; potenciales evocados postoperatorios, presencia de defecto estético y proptosis pulsátil. Buenos resultados fueron: Karnofsky mayor de 70, no recurrencia tumoral y no emperoramiento de potenciales Visuales; regulares: sin recurrencia tumoral y no empeoramiento de Potenciales Visuales; regulares: sin recurrencia tumoral, cambio en potenciales evocados, escala de Karnofsky entre 50 y 60; malos: recurrencia, lesión visual agregada en potenciales evocados y Karnofsky menor de 50. El reporte muestra la variedad de lesiones intraorbitarias que pueden ser abordadas por vía transcraneal

ABSTRACT

Objetivo. Describir las características clínicas y etiológicas en niños con síndrome de Parinaud. Material y métodos. De 1987 a 1996 se estudiaron 11 pacientes con edades entre 10 meses y 14 años con un promedio de 10 años. Todos los pacientes competaron los criterios clínicos de síndrome de Parinaud. Resultados. La etiología fue tomoral en siete pacientes (4 con germinoma de la región pineal, y 3 secundarios a teratoma, astrocitoma, y tumor talámico). En los 4 casos restantes el diagnóstico fue quiste aracnoideo del II ventrículo, cisticercosis, tuberculoma y esclerosis múltiple. El manejo fue principalmente de remoción quirúrgica y colocación de válvula de derivación ventrículo-peritoneal en los casos de hidrocefalia por obstrucción en la dinámica del líquido cefalorraquídeo; la quimioterapia se adicionaron al tratamiento en los casos de tumor; el empleo de esteroides se limitó al caso de esclerosis múltiple, y el tratamiento antifimico al tuberculoma. Conclusiones. El síndrome de Parinaud en niños difiere clínica y etiológicamente de lo observado en adultos. Los procesos tumorales ocurrieron en más del 60 por ciento de los niños. La atención en estructuras diencefálicas por procesos tumorales ocurrieron en más del 60 por ciento de los niños. La alteración en estructuras diencefálicas por procesos ocupativos interrumpieron conexiones aferentes de las estructuras de la comisura posterior, el riMFLo del núcleo intersticial de Cajal en nuestros casos
