The non-SC subtype was an independent prognostic factor for both worse PFS (adjusted-HR = 1.62; p = 0.016) and OS (adjusted-HR = 1.64; p = 0.015), whereas a Ki-67 index of ≥55% (significantly enriched in the SC subgroup; Table 1 ) was an independent prognostic factor for worse PFS (adjusted-HR = 1.80; p = 0.028) and showed a trend towards worse OS (adjusted-HR = 1.63; p = 0.067).
