highly significantP < .001
The univariate HR for OS of the development of new lesions was highly significant (HR = 5.27, P < .001) and increased after correction for other variables in a multivariate analysis (HR = 7.03, P < .001).
The univariate HR for OS of the development of new lesions was highly significant (HR = 5.27, P < .001) and increased after correction for other variables in a multivariate analysis (HR = 7.03, P < .001).
HRs were borderline significant at ≥40% (HR = 1.76, P = .056) and not significant at ≥20% increase at first follow-up; at second follow-up the highest significant HR was found with the ≥20% increase threshold (HR = 10.70, P < .001).
