BACKGROUND: Both serum elevation of C-reactive protein (CRP) and reduction of lymphocyte in the peripheral blood has been known as indicator for malignant potential of human tumors. METHODS: Whether newly devised CLS (CRP/Lymphocyte Score), based on combined data of serum elevation of CRP and of lymphocyte percentage in the peripheral blood can be an indicator for progressive potential in colorectal carcinoma was examined in 280 cases who had been surgically treated. RESULTS: Significant difference in survival was observed both between CLS 0 and 1 and between CLS 1 and 2, in both cases when analyzed among whole patients and patient who had been treated with curative resection. Multivariate analysis among patients who had been treated with curative resection demonstrated that CLS (P < 0.0001), histologic type (P = 0.0003), and tumor stage (P = 0.039) were factors independently associated with worse prognosis of the patients. CONCLUSIONS: Newly devised criteria CLS could be an independent prognostic indicator in colorectal carcinoma and would be utilized as a helpful information. J. Med. Invest. 66 : 264-268, August, 2019.
