A highly significant association was found between TSR and tumour grade ( P < 0.001) and lymphovascular space invasion ( P < 0.001), both of which had independent prognostic significance in this study population.

Univariable Cox proportional hazards analysis of logTSR as a continuous variable showed that increased TSR was significantly associated with worse OS ( P = 0.032) and showed a trend towards associating with poorer DFS (P = 0.058) (Table 2 ).
