Table 4 Uni- and multivariable analysis of RFS and OAS for various high risk subgroups of pN1-patients stratified by LN ratio for pN1-patients with 10 ≤ or more than 10 LN excised

From: Does the number of removed axillary lymphnodes in high risk breast cancer patients influence the survival?

Number of excised LN LN ratio univariate multivariatea
≤10 RFS P < 0.001; HR = 5,47; (95% CI 2,30-13,4) P < 0.001; HR = 5,34; (95% CI 2,24-12,70)
OAS P < 0.001; HR = 4,30; (95% CI 2,28-8,10) P = 0.001; HR = 2,99; (95% CI 1,50-5,56)
> 10 RFS P < 0.001; HR = 6,45; (95% CI 4,74-8,78) P < 0.001; HR = 4,57; (95% CI 3,29-6,36)
OAS P < 0.001; HR = 6,29; (95% CI 4,77-8,30) P < 0.001; HR = 3,40; (95% CI 2,53-4,56)
