showed a trendP =0.055
A subset analysis of stage 3 patients showed a trend associating poor survival with serum RASSF1A methylation ( P =0.055), although the data were limited due to the small number of patients in the subgroup.
A subset analysis of stage 3 patients showed a trend associating poor survival with serum RASSF1A methylation ( P =0.055), although the data were limited due to the small number of patients in the subgroup.
In multivariate analysis of survival, methylation of RASSF1A in serum had a hazard ratio of 2.4 (95% CI, 0.6–9.2), although this association did not reach statistical significance ( P =0.194).
