Full description

This is a phase II study to determine the efficacy and safety of Pembrolizumab when given in combination with Lenvatinib as treatment for patients with the advanced kidney cancer . Further evaluate whether the treatment is beneficial to operation. Patients will receive treatment with Pembrolizumab in combination with Lenvatinib every 3 weeks for 3 cycles in the preoperation. Additional 17 cycles of Pembrolizumab were needed for patients with high risk of recurrence (tumor stage 2 with nuclear grade IV or sarcomatoid differentiation, tumor stage 3 or higher, regional lymph-node metastasis, or stage M1 with no evidence of disease residual).
