About

Through the neoadjuvant treatment with a combination of Cardonilli and Lenvatinib, it enabled the successful and safe implementation of partial nephrectomy in patients with localized renal cancer, who had indications for nephron-sparing surgery but faced considerable difficulty in preserving the kidney (T1b with an endophytic component ≥75% or T2)
