Chronic kidney disease (CKD), cancer and haematological diseases share areas of reciprocal influence. Cancer can affect the kidney either as glomerular lesions or as a result of the toxic effects of medication or radiation with acute (thrombotic microangiopathy, acute kidney injury, interstitial nephropathies among others) or chronic processes (worsening of CKD after nephrectomy due to renal cancer, interstitial fibrosis, hydroelectrolytic disorders). On the other hand, patients who require renal replacement therapy with dialysis and particularly with kidney transplantation are at high risk of onset of cancer due to the immunosuppression situation that they generate. In addition to conventional chemotherapy, innovative treatments have been developed: target agents against growth factors and their receptor; anti-angiogenic drugs; immunoregulatory proteins; cell cycle regulators; and enzyme inhibitors. Other immunotherapeutic approaches have also been developed, such as vaccines, adoptive cell therapy (CAR T cells) or development of antibodies. All these therapeutic advances will improve the outcomes against cancer and haematological diseases, but they are not free from secondary renal problems. Onco-Nephrology is already an important area for the Spanish Society of Nephrology with a large number of inter-consultations. Nephrologists need a better understanding of rapidly evolving areas of cancer biology and its treatment in order to become valued members of the cancer care team and to provide the best nephrology care possible.

Treatment with chimeric antigen receptor-modified T cell (CAR-T) has demonstrated promising therapeutic efficacy in hematologic malignancies. However, the therapeutic efficacy is still very limited for solid tumors. An immunosuppressive microenvironment is one of the main reasons for the limited efficacy. Some chemotherapeutic agents exhibit immune microenvironment modulation. Therefore, combination with chemotherapeutic agents may be one of the promising strategies to enhance the therapeutic efficacy of CAR-T against solid tumors. Sunitinib modulates the antitumor immune response by improving T-cell infiltration and function while reducing immunosuppressive factors. The authors constructed a second-generation CAR targeting human renal cell carcinoma (RCC)-specific antigen carbonic anhydrase IX (CAIX) with the costimulatory domain of 4-1BB. The results of cytokine releasing and cell killing assays showed that the CAIX-CAR-T cells have specific effector functions against CAIX renal cancer cells in vitro. Combination therapy with CAIX-CAR-T and sunitinib showed synergistic efficacy against a mouse lung metastasis model of human RCC. CAIX-CAR-T cells in the mice of the combination therapy group showed stronger proliferation and tumor infiltration than that in the mice of the CAIX-CAR-T monotherapy group. The possible mechanisms of the synergistic efficacy are: (1) sunitinib caused upregulation of CAIX in tumor cells; (2) sunitinib decreased frequency of myeloid-derived suppressor cells in the tumor microenvironment. Our study supplied an innovative immunotherapeutic approach whereby combining CAIX-CAR-T with sunitinib induces a potent antitumor response in an experimental model of metastatic RCC. The combination strategy should be considered as a potential approach to augment adoptive CAR-T cell immunotherapy.
