Objective:
To evaluate the efficacy of using the lymphocyte-monocyte ratio (LMR), hemoglobin-platelet ratio (HPR), and carcinoembryonic antigen (CEA) levels alone or in combination for diagnosing colon cancer.
Methods:
We assessed 124 consecutive patients who were pathologically diagnosed with colon cancer and 131 patients who were diagnosed with benign colon tumors in this retrospective study. We then analyzed correlations between LMR, HPR, and clinicopathological findings. The diagnostic values of LMR, HPR, and CEA alone or in combination in colon cancer patients were evaluated by receiver operating characteristic curves.
Results:
The median LMR, HPR, and CEA values in colon cancer patients showed significant correlation with the depth of tumor invasion, lymph node metastasis, and TNM stage. Moreover, there was a significant difference in HPR between patients with tumor size ≥5 cm and those with tumor size <5 cm. Compared with LMR, HPR, or CEA alone, combinations of CEA with LMR, CEA with HPR, and HPR with LMR all had higher area under the curve values, among which the combination of all three (LMR, HPR, and CEA) had the highest area under the curve.
Conclusion:
The combination of LMR, HPR, and CEA may be a valuable indicator for monitoring colon cancer.
