Niveles de invasi\u00f3n en un adenoma pediculado (izquierda) y un adenoma s\u00e9sil (derecha). La zona punteada representa zonas de carcinoma. Obs\u00e9rvese que cualquier invasi\u00f3n por debajo de la muscular de la mucosa en una lesi\u00f3n s\u00e9sil representa invasi\u00f3n de nivel 4. En contraste, el carcinoma invasivo en un adenoma pediculado (izquierda) debe atravesar una distancia considerable antes de alcanzar la submucosa de la pared intestinal subyacente. La l\u00ednea punteada en la cabeza del adenoma pediculado representa la zona de invasi\u00f3n de nivel 1.

<\/p>\n\n\n\n

Para las lesiones pediculadas, los niveles de invasi\u00f3n de Haggitt 1, 2 y 3 (nivel 0: carcinoma no invasivo; nivel 1: invasi\u00f3n de la cabeza del p\u00f3lipo pediculado; nivel 2: invasi\u00f3n del cuello del p\u00f3lipo pediculado; nivel 3: invasi\u00f3n del ped\u00edculo del p\u00f3lipo pediculado) corresponden a sm1, y el nivel 4 (nivel 4: invasi\u00f3n de la base del p\u00f3lipo pediculado) se subdivide en sm1, sm2 o sm3. Las lesiones s\u00e9siles se consideran todas como nivel 4 de Haggitt.<\/p>\n\n\n\n

La incidencia de met\u00e1stasis del nivel 0 al 3 es muy peque\u00f1a, y es a partir del nivel 4 (invasi\u00f3n de la submucosa) cuando se observan met\u00e1stasis ganglionares en hasta el 10% de los casos. Se a\u00f1ade adem\u00e1s que la invasi\u00f3n de la submucosa hasta una profundidad de 1000 micr\u00f3metros (sm1) presenta una tasa de met\u00e1stasis ganglionares muy baja.<\/p>\n\n\n\n

Una polipectom\u00eda puede considerarse tratamiento suficiente si se asegura la resecci\u00f3n de la totalidad de la lesi\u00f3n, si la evaluaci\u00f3n anatomopatol\u00f3gica puede realizarse con seguridad, si el carcinoma es bien diferenciado, si no presenta invasi\u00f3n linf\u00e1tica o vascular y si el margen de escisi\u00f3n est\u00e1 libre.<\/p>\n\n\n\n

La distancia m\u00ednima requerida entre el margen libre de resecci\u00f3n y la lesi\u00f3n tumoral es incierta, variando entre 1 y 2 mm seg\u00fan las diferentes series. Sin embargo, un margen inferior a 1 mm es un factor de alto riesgo de recidiva.<\/p>\n\n\n\n
