Abstract
Colorectal cancer (CRC) is a common and mortal disease. Chronic kidney disease (CKD) is the relatively common comorbidity among cancer patients affecting the available therapy and outcomes. However, data on prevalence of CKD in patients with CRC undergoing surgery is limited. The aim of the study was to evaluate the prevalence of CKD in a cohort of 560 consecutive patients with CRC undergoing surgical treatment with curative intent. Neoadjuvant therapy in a form of radiotherapy or radiochemotherapy was administered before the surgery in 67 patients and in 86 patients, respectively. Results: CKD was reported in 10%, diabetes in 25%, and hypertension in 60%, while anemia was reported in 47%. The patients with CKD were more likely to be older and anemic with higher serum CRP, which reflects a general inflammatory state. Relative to patients without this therapy, patients undergoing neoadjuvant radiochemotherapy were older, had significantly lower eGFR and albumin, and higher creatinine, aspartate aminotransferase and INR, before the surgery. All CKD patients, except two, were older than 65 years of age. Conclusions: In order to ensure the best possible outcomes, CKD should be diagnosed and treated appropriately in oncology patients to prevent complications, so they may continue their therapy with the least interruption or discontinuation of treatment.
