3.4 L1CAM affects prognosis through its effect on platinum resistance In multivariate survival analysis, adjusted for age, FIGO stage and tumour grade, L1CAM IHC showed a significant association with DSS (HR: 2.03, 95% CI: 1.12‐3.66, P = .019) and a borderline significant effect on PFS (HR: 1.60, 95% CI: 1.00‐2.56, P = .051); these results confirm L1CAM as an independent adverse prognostic factor (Figure 3A‐C ).
