Review
Rational selection of a control arm for randomised trials in metastatic renal cell carcinoma.
Immunotherapy, and only immunotherapy, has reproducible, albeit limited efficacy in metastatic renal cell cancer (MRCC). Further improvement is warranted and progress will have to be investigated in randomised clinical trials, because the variable natural history of this disease precludes firm conclusions outside the context of controlled clinical studies. Currently, there is no general accepted standard arm to compare for those randomised clinical protocols. This needs to be established, which is the goal of this project. ⋯ An appealing safety profile, the applicability in an outpatient regimen, the possibility of less stringent selection criteria, and the proven life prolonging effect will make adjuvant monotherapy, in particular IFN-alpha monotherapy, after a tumournephrectomy currently the control-arm of choice in randomised trials for MRCC.
