The risk of solid organ tumors in patients with chronic kidney disease: A narrative review of literature

Chronic kidney disease (CKD) has been correlated with certain pathological conditions such as cardiovascular diseases and other renal-related dysfunctions. Some other reports suggested an association between CKD and the development of certain solid cancers. Therefore, we aimed to generate this narrative review to present the available literature on the risk of solid cancer development in CKD patient populations. We explored the associations between CKD, organ transplantation, and the development of specific solid organ tumors such as kidney, thyroid, lung, breast, bladder, gastric, and prostate cancers. In conclusion, the previous reports showed an increase in the risk of certain solid cancers such as kidney, lung, bladder, and possibly breast cancer in CKD patients and transplant recipients. On the other hand, thyroid, gastric, and prostate cancers showed unclear association with CKD. Despite the suggested impact of smoking and immunosuppression on the development of cancers in CKD patients, more studies are needed to elucidate the mechanism and the risk factors that might be related to the development of cancer in CKD patients.
