Fig. 6. GITR/GITRL were highly expressed in nonepithelioid MPM and negatively correlated with survival after the SMART approach.

a Kaplan–Meier survival analysis of all MPM patients demonstrates that patients with epithelioid subtype (Epi.) had better survival than those with nonepithelioid subtype (non-Epi.) with a median survival of 28.6 (Epi.) versus 15.9 months (non-Epi.) (P < 0.0001). b GITR and GITRL levels by immunohistochemistry in epithelioid and nonepithelioid MPM; immunohistochemistry results were quantified by Definiens Tissuestudio 4.0 software. *P < 0.05, determined by Mann–Whitney U test. c Correlation between expression of GITR and GITRL (p = 0.0018, r = 0.3115). d Risk analysis of patients with epithelioid and nonepithelioid subtype who died from mesothelioma after the SMART approach to determine the correlation between GITRL and GITR and length of survival. e Kaplan–Meier survival analysis in nonepithelioid MPM showed that high expression of GITRL and GITR was associated with worse survival after SMART. In epithelioid MPM, high expression of GITRL was associated with better survival after SMART.
