ABSTRACT
New surgical techniques in the treatment of rectal cancer have improved survival mainly by reducing local recurrences. A preoperative staging method is required to accurately identify tumor stage and planning the appropriate treatment. MRI and ERUS are currently being used for the local staging (T stage). In this review, the accuracy of MRI and ERUS with rigid probe was compared against the gold standard of the pathological findings in the resection specimens. Five studies met the inclusion criteria and were included in this meta-analysis. The accuracy was 91.0% to ERUS and 86.8% to MRI (p=0.27). The result has no statistical significance but with pronounced heterogeneity between the included trials as well as other published reviews. We can conclude that there is a clear need for good quality, larger scale and prospective studies...
RESUMEN
Las nuevas técnicas quirúrgicas en el tratamiento del cáncer de recto han mejorado la supervivencia, principalmente mediante la reducción de las recidivas locales. Se requiere un método de estadificación preoperatoria para identificar con precisión el estádio del tumor y planificar el tratamiento adecuado. RNM y EAR actualmente están siendo utilizados para la estadificación local (estadio T). En esta revisión, La exactitud de la RNM y la EAR con sonda rígida se comparo com el patrón oro de los hallazgos patológicos em las muestras de resección. Cinco estudios cumplieronloscriterios de inclusión y fueron incluídos en este meta-análisis. La precisión fue 91,0% a 86,8% y EAR a la RNM (p=0,27). El resultado no tiene significación estadística pero com heterogeneidad marcada entre los ensayos incluidos, así como otras revisiones publicadas. Podemos concluir que existe una clara necesidad de buena calidad, a mayor escala y estudios prospectivos...
