ABSTRACT

Existe una importante controversia en el manejo quirúrgico del cáncer de cardias. Parece unánime que los tumores tipo i de Siewert se intervengan como un cáncer de esófago y los Siewert III como un cáncer gástrico. Sin embargo, sobre el «verdadero» cáncer de cardias o Siewert II no existe consenso. Es obvia la necesidad de un margen proximal y distal libre, así como una correcta linfadenectomía. Para algunos es necesaria la esofaguectomía para realizar una correcta cirugía oncológica radical, pero otros autores defienden que es suficiente con un abordaje abdominal para realizar una gastrectomía total y esofaguectomía distal. Tanto los trabajos publicados con cierta antigüedad como aquellos más recientes no aclaran este dilema y sus resultados son contradictorios. El hecho de realizar un tratamiento quimioterápico previo a la cirugía, puede reducir el tamaño tumoral y la presencia de adenopatías, por lo que las opciones quirúrgicas pueden haber cambiado en los últimos años


There is significant controversy in the management of cardiac cancer. It seems unanimous that Siewert type I tumors be operated on as cancer of the esophagus and Siewert type III as gastric cancer. However, for "true" cancer of the gastric cardia or Siewert II, the authors do not agree. There is the obvious need for free proximal and distal margins, as well as correct lymphadenectomy. For some, esophagectomy is necessary to perform correct radical oncological surgery, but other authors defend that an abdominal approach is sufficient to perform total gastrectomy and distal esophagectomy. Recent and older papers published do not clarify this issue, and their results are contradictory. Chemotherapy prior to surgery can reduce the size of the tumor and the presence of lymphadenopathies

ABSTRACT

Las nuevas tecnologías de imagen con endoscopios de alta resolución y el uso de la cromoscopia asociado al entrenamiento de los endoscopistas han permitido detectar lesiones neoplásicas de esófago en estadios iniciales. Estos avances resultaron en la expansión de las indicaciones del tratamiento endoscópico curativo en pacientes con carcinoma de células escamosas de esófago. En los últimos años se han desarrollado técnicas para la resección endoluminal en bloque de los tumores gastrointestinales precoces, procedimiento denominado disección endoscópica de la submucosa (DES). Inicialmente la DES fue utilizada para tratamiento de tumores gástricos, y posteriormente esta técnica pasó a ser aplicada para tumores de esófago y colorectales. El presente artículo de revisión presenta una descripción de la DES en el manejo de las neoplasias superficiales de esófago, a fin de contribuir para la difusión de este concepto y la incorporación de este procedimiento en Latinoamérica.


The development of high-resolution endoscopes with chromoendoscopy and the education of endoscopists have enabled the detection of early stage esophageal squamous-cell carcinoma (ESCC). Moreover, in recent years there has been an important progress in the management of early gastrointestinal neoplastic lesions after the development in Japan of endoluminal techniques for en-block tumor resection, namely endoscopic submucosal dissection (ESD). The combination of these factors facilitated the expansion of indications for endoscopic minimally invasive curative interventions in selected patients with superficial ESCC. This review article presents a comprehensive overview and detailed description of the ESD procedure for treatment of ESCC in order to facilitate the dissemination of this concept and the incorporation of this new technique in Latin-America.

ABSTRACT

BACKGROUND: The esophageal cancer is one of the most common and aggressive worldwide. Recently, the AJCC changed the staging system, considering, among others, the important role of the lymph node metastasis on the prognosis. AIM: To discuss the applicability of different forms of lymph node staging in a western surgical center. METHODS: Four hundred eighty seven patients with esophageal cancer were enrolled. Three staging systems were evaluated, the 6th and the 7th AJCC editions and the Lymph Node Metastatic Ratio. RESULTS: The majority of the cases were squamous cell carcinoma. The mean lymph node sample was eight. Considering the survival, there was no significant difference between the patients when they were classified by the 7th AJCC edition. Analysis of the Lymph Node Metastatic Ratio, just on the group of patients with 0 to 25%, has shown significant difference (p=0,01). The 6th AJCC edition shows the major significant difference between among the classifications evaluated. CONCLUSION: In this specific population, the 7th AJCC edition for esophageal cancer was not able to find differences in survival when just the lymph node analysis was considered. .


RACIONAL: O câncer de esôfago é um dos mais comuns e agressivos que existem. Recentemente o AJCC mudou o sistema de estadiamento, considerando, entre outros fatores, a importância da metástase linfonodal sobre o prognóstico. OBJETIVO: Discutir a aplicabilidade de diferentes formas de estadiamento linfonodal em um serviço de cirurgia ocidental. MÉTODOS: Quatrocentos e oitenta e sete pacientes com câncer de esôfago foram arrolados. Três estadiamentos foram avaliados, a 6a e a 7a Edição do AJCC e o Índice de Metástase Linfonodal. RESULTADOS: A maioria foi casos foi composta por carcinoma epidemóide. A média de amostra linfonodal foi de oito. Considerando a sobrevida, não houve diferença significativa entre os pacientes quando foram classificados pela 7a Edição do AJCC. Analisando o Índice de Metástase linfonodal, apenas o grupo de pacientes com 0-25% mostrou diferença significativa (p=0,01). A 6a Edição do AJCC mostrou a maior diferença entre as classificações avaliadas. CONCLUSÃO: Considerando as características da amostra, a nova classificação do AJCC não foi capaz de evidenciar diferenças significativas na sobrevida dos pacientes, quando apenas o estadiamento linfonodal foi avaliado. .

ABSTRACT

BACKGROUND: Genomic aberration is a common feature of human cancers and also is one of the basic mechanisms that lead to overexpression of oncogenes and underexpression of tumor suppressor genes. Our study aims to identify frequent genomic changes and candidate copy number driving genes in esophageal squamous cell carcinoma (ESCC). METHODS: We used array comparative genomic hybridization to identify recurrent genomic alterations and screened the candidate targets of selected amplification regions by quantitative and semi-quantitative RT-PCR. RESULTS: Thirty-four gains and 16 losses occurred in more than 50 % of ESCCs. High-level amplifications at 7p11.2, 8p12, 8q24.21, 11q13.2-q13.3, 12p11.21, 12q12 and homozygous deletions at 2q22.1, 8p23.1-p21.2, 9p21.3 and 14q11.2 were also identified. 11q13.2 was a frequent amplification region, in which five genes including CHKA, GAL, KIAA1394, LRP5 and PTPRCAP were overexpressed in tumor tissues than paracancerous normal tissues. The expression of ALG3 at 3q27.1 was higher in ESCCs, especially in patients with lymph node metastasis. CONCLUSIONS: Target gene identification of amplifications or homozygous deletions will help to reveal the mechanism of tumor formation and explore new therapy method (AU)

ABSTRACT

PURPOSE: There is an urgent need to identify biomarkers for early diagnosis and prognosis of esophageal cancer. The present study was undertaken to test whether circulating autoantibodies to ATP-binding cassette C3 (ABCC3) transporter could serve as a biomarker for the malignant tumor. METHODS: An enzyme-linked immunosorbent assay approach was developed in-house to test circulating autoantibodies to ABCC3 in 114 patients with esophageal squamous cell carcinoma (ESCC) and 226 healthy subjects well matched in age and smoking history. RESULTS: Mann-Whitney U test showed that the IgA antibody levels were significantly higher in patients with ESCC than control subjects (Z = -4.226, P < 0.001) while the IgG antibody levels were not significantly different between the two groups (Z = -1.072, P = 0.284). The sensitivity against >95 % specificity was 13.2 % for the IgA assay with an inter-assay deviation of 13.0 and 7.9 % for the IgG assay with an inter-assay deviation of 9.4 %. CONCLUSIONS: This work suggests that circulating IgA autoantibody to ABCC3 may be a potential biomarker for ESCC, which could be used for early diagnosis and prognosis of the malignant tumor (AU)

ABSTRACT

BACKGROUND/AIMS: The aim of this study was to evaluate clinicopathologic differences between Type II and Type III groups that were classified by Siewert in cardia cancer. METHODS: A hundred forty-one patients who were diagnosed as gastric cardia cancer and underwent surgery between January 1990 and December 2006 by single surgeon at Department of Surgery, Yonsei University College of Medicine were included in this study. The Kaplan-Meier method and log rank test were used for survival analysis. RESULTS: Barrett's adenocarcinoma was recognized in two patients so called type I. There were significant differences between type II and III in aspect of depth of invasion, Lauren's classification, and the number of retrieved lymph nodes in which cancer infiltrated. In type III, prognostic factors affecting survival were depth of invasion and nodal status in contrast to the no demonstrable prognostic factors existing in type II. However, there were no differences in recurrence and survival between two groups. CONCULSIONS: Several clinicopathologic differences exist between type II and III cardia cancer. In the future, further evaluation is needed regarding the classification and entities of the cardia cancer.

ABSTRACT

Vascular endothelial growth factor (VEGF) is known to play a key role in tumor angiogenesis. The tumor-suppressor gene p53 has been thought to regulate VEGF. We investigated the effect of VEGF on esophageal carcinoma and the correlation between VEGF and p53. Tissue samples were taken from 81 patients with esophageal carcinoma after surgery. VEGF and p53 expressions were examined by immunohistochemical staining. Microvessels in the tumor stained for CD34 antigen were also counted. VEGF and p53 expressions were observed in 51.3% (41/80) and 51.9% (41/79), respectively. The microvessel density was 70.9+/-6.7 (mean+/-SE) in VEGF-positive group and 68.7+/-5.1 in VEGF-negative group. However, no correlation was noted between VEGF and p53 expression. Whereas the tumor size, nodal status, depth of invasions, and tumor stage were associated with poor overall survival, VEGF expression or p53 expression was not. These results indicate that VEGF and p53 are highly expressed in esophageal carcinomas. Since the VEGF expression is not correlated with the p53 expression, microvessel density or clinicopathological findings, further studies with other angiogenic molecules are needed to determine the role in esophageal carcinomas.

ABSTRACT

El cáncer del esófago es una de las patologías neoplásicas con mayor variabilidad geográfica, en donde el común denominador parece ser la pobreza. La incidencia habitualmente reportada de 3 x 100,000 en países occidentales, contrasta con un 140 x 100,000 en el denominado cinturón del cáncer esofágico en Asia Central. Entre los muchos agentes causales destacan por su consistencia el consumo de alcohol y de tabaco. La variedad histológica más frecuentemente reportada sigue siendo el carcinoma epidermoide, aunque en las últimas décadas, se ha observado un viaje hacia el adenocarcinoma, fenómeno que se puede explicar al incluir tumores de la unión esofagogástrica así como la participación del epitelio metaplásico de barrett y la enfermedad por reflujo. Al igual que la mayoría de esta enfermedad es habitualmente tardió, explicando de esta manera el mal pronóstico que en general tiene. Dentro de las manifestaciones clínicas más frecuentes, sigue siendo la disfagia el síntoma pivote, acompañada de odinofagia, hemorragia, síntomas respiratorios, disfonía y ataque al estado general. Los estudios diagnósticos en estadios avanzados son habitualmente confirmatorios. La combinación de los estudios contrastados y la endoscopia proporciona el diagnóstico centero en más del 95 por ciento y éstos no deben ser excluyentes entre sí sino complementarios. La tomografía axial computada resulta ser el método convencional para la etapificación clínica, siendo además un estudio fundamantal que puede definir cambios en el abordaje terapéutico. La confirmación de progresión tumoral extraesofágica justifica el tratamiento no quirúrgico. El ultrasonido transendoscópico está siendo considerado como una mejor alternativa en el proceso etapificador en cáncer del esófago. Se requiere para su aplicación, que la lesión permita el paso del instrumento y hoy en día sólo algunos centros en nuestro país cuentan con esta tecnología que lo excluye como un estudio rutinario. Salvo algunas excepciones, el tratamiento para la mayoría de los pacientes tiene un fin paliativo. De las múltiples alternativas quirúrgicas existentes, es la esofagectomía transhiatal sin toracotomía la que más se utiliza en los padecimientos obstructivos del esófago. La controversia continúa en torno al concepto de que esta técnica no cumple con los principios oncológicos de hacer una buena linfadenectomía mediastinal. Sin embargo, también es aceptado que el pronóstico depende más de la biología y estadio del tumor...

ABSTRACT

Los tumores benignos de esófago constituyen una entidad patológica poco frecuente, ocupando el 0,5 a 0,8 por ciento de las neoplasias de esófago. Se dividen en intraluminales, intramurales y extramurales. Se localizan más frecuentemente en el tercio distal y la mayoría corresponden a leiomiomas (50 por ciento). Otros tipos de lesiones son los fibromas, lipomas, neurofibromas y pólipos. Los leiomiomas se presentan en gente joven. La edad promedio de presentación es de 38 años. Pueden ser múltiples (3-10 por ciento). Se diagnostican con radiografía de esófago estómago y duodeno e idealmente con ecografía endoscópica. El tratamiento ideal es la enucleación quirúrgica que se efectúa en los tumores mayores de 5 cm. Entre los otros tumores el schwannoma es el tumor primario benigno más frecuente del mediastino, aunque representa sólo el 8 por ciento de todos ellos. Se presenta más frecuentemente en la mujer entre la quinta y sexta década de la vida. La biopsia endoscópica tiene un alto porcentaje de error. Se presenta caso clínico de una paciente con un schwannoma esofágico que se intervino en nuestro servicio practicándose una esofagectomía parcial con buen resultado

ABSTRACT

El cáncer de esófago es una de las patologías difíciles de tratar, básicamente por razones que involucran tardanza en el diagnóstico debido a que cuando el paciente presenta los síntomas iniciales como disfagia, el cáncer se encuentra ya en un estadio avanzado, frente a lo cual las alternativas de tratamiento quirúrgico en la gran mayoría son de carácter paliativo, y deben er analizadas correctamente, guiadas a obtener un adecuado tránsito digestivo para de esta manera ayudar a que los pacientes con esta enfermedad tengan una vida digna y puedan llegar hasta sus útlimos días, con la satisfacción de cunmlplir con una de las funciones básicas del ser humano que es el poder comer...

ABSTRACT

El cáncer de esófago es uno de los cánceres menos frecuentes del tracto digestivo, usualmente de diagnóstico tardío, difícil de tratar quirúrgicamente, y esta entre los de peor pronóstico. Se revisa en el presente artículo aspectos sobre su epidemiología, patogénesis, clínica, metodología de diagnóstico y de estadiaje; así como de tratamiento. La cirugía en el cáncer de esófago en el estadío incipiente o superficial ofrece una sobrevida notable a 5 años, casi 100 por ciento en los primeros. Sin embargo, no existe consenso actual respecto a la mejor forma de tratamiento del cáncer de esófago en estadío avanzado, en el que usualmente se hace el diagnóstico, y a pesar de los progresos, la sobrevida a 5 años permanece en el 5 a 10 por ciento. En este estudio examinaremos también aspectos del tratamiento quirúrgico; de irradiación y quimioterapia, así como sobre la combinación de ellos; y la terapia con laser, electrocoagulación bipolar, y con dilataciones e intubación
