## Relevancia
Cáncer de esófago/UGE tras quimiorradioterapia CROSS o quimioterapia FLOT: aborda pCR ganglionar, supervivencia según yp-stage y patrones de diseminación nodal. Análogo a mama: el ypN0 es el factor pronóstico independiente más robusto tras tratamiento neoadyuvante.

## Abstract
Data from 301 consecutive patients with potentially curable adenocarcinoma of the distal esophagus and GEJ who received neoadjuvant treatment followed by surgery. Median 33 nodes recovered. 117 (38.9%) ypN0 vs 184 (61.1%) LN positive. Median survival ypN0 = 171 months vs 24 months ypN+ (P<0.001). Multivariate analyses identified ypT, ypN, male gender, and nonradical margin as significant prognostic factors. Surgical dissection of nodes enables accurate LN assessment and provides valuable information about the pattern of nodal spread.
