This relation was not observed for CEA values 57.1%, p=0.12. When values were adjusted according to age group under and over 55 years, no significant changes in the relation between tumor location and preoperative DD values RR= 1.22, CI 95%, 1.00 to 1.42 or preoperative CEA values RR = 1.26, CI 95%, 0.93 to 1.69 were detected. Similarly, adjusting for age did not result in any significant changes in relations of values observed in postoperative monitoring. DD values were RR= 1.02, CI 95%, 0.80 to 1.29, and CEA values were RR = 0.83, CI 95%, 0.53 to 1.31.
Cuando se ajustó según el grupo de edad menor o mayor a 55 años, no hubo cambios significativos en la asociación de la ubicación tumoral con el DD preoperatorio RR = 1,22; IC 95%: 1,00 a 1,42 y el ACE preoperatorio RR = 1,26; IC 95%: 0,93 a 1,69; de igual manera ocurrió con el DD seguimiento RR = 1,02; IC 95%: 0,80 a 1,29 y ACE seguimiento RR = 0,83; IC 95%: 0,53 a 1,31.
