borderline significanceP =0.099
When the analysis was confined to the 123 patients who proceeded to HDCT/ASCR as assigned at diagnosis (57 single and 66 tandem), the probability of 5-yr RFS after the first HDCT was higher in the tandem group than in the single group with borderline significance (59.1%±13.5% vs.41.6%±14.5%, P =0.099, Fig. 2B ).
