Background:
In cancer treatment of the elderly, it is important to grasp the"degree of inflammation"and"nutritional status"in advance.
Objective:
This study aims to investigate the usefulness of preoperative modified Glasgow Prognostic score(mGPS)evaluation in elderly patients with colorectal cancer.
Patient:
89 cases of primary resection of colorectal cancer over 80 years old were enrolled.
Methods:
In the preoperative mGPS score normal group(score 0)and abnormal group (scores 1 or 2)were divided. Clinicopathological factors(patient-related 13 factors, treatment-related 6 factors, and tumor-related 4 factors)were compared, and the long-term results were also investigated.
Results:
Between 42 cases in the normal group and 47 cases in the abnormal group, there were significant differences(p<0.05)in 6 factors: BMI, total protein, cholinesterase, neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, and Onodera prognostic nutritional index. The long-term results(5-year survival rate)were also significantly different in the normal group(76.8%)and the abnormal group(51.6%)(p=0.007).
Conclusion:
Even in elderly patients with colorectal cancer, preoperative suppression of inflammatory conditions and improvement of nutritional status may contribute to the improvement of long-term prognosis, so mGPS evaluation is useful.
