N=53 patients were evaluable for this analysis. Patients were inevaluable mainly because the PFS1 was in the adjuvant/neoadjuvant setting or was a matched therapy.
Age cut-off chosen corresponds to the median age.
The cut-off of 50% for the Matching Score was chosen according to the minimum P-value criteria.19
Combination therapy refers to administrations of molecularly matched multi-drug regimens.
Cut-off chosen was the median line of therapy administered.
PFS2 refers to progression-free survival on the I-PREDICT protocol; PFS1 refers to progression-free survival on the prior unmatched therapy (in a metastatic or an unresectable setting).
P-values by Kaplan-Meier method [two-sided log-rank test (univariable analysis); Cox regression (multivariate analysis)]; variables with P<0.3 in univariable analysis were included in the Cox regression model (multivariable analysis).
