Abstract:

Objective To determine the level of red cell distribution width(RDW) in peripheral blood of patients with prostate cancer,and to investigate the correlation between RDW and prostate cancer. Methods Totally,497 patients diagnosed with prostate cancer in Xuhui Central Hospital from January 1,2016 to June 1,2020 were enrolled,and 519 healthy subjects in the same period were enrolled as control group. A total of 100 patients with prostate cancer from January 1,2016 and June 30,2017 were enrolled and followed up for 3 years. Detailed physical examination and blood examination results of 88 patients were collected. The data,such as age,weight,diabetes mellitus,hypertension,smoking history and alcohol consumption history,were collected. RDW levels were determined. The correlation between RDW and prostate cancer was evaluated. The subjects were further classified into 4 subgroups(<60,60-69,70-79 and >80 years old) according to ages. Their RDW levels were compared. Results Compared with control group,RDW level in prostate cancer group was higher than that in control group(P<0.001). In the age subgroups,the RDW level in prostate cancer group was increased compared with that in control group(P<0.001). Multivariate binary Logistic regression analysis found that RDW increased [odds ratio(OR)=3.300,95% confidence interval(CI) 2.290-4.753,P<0.001,body mass index increased(OR=1.086,95% CI 1.003-1.177,P=0.042) and t-PSA increased(OR=1.255,95% CI 1.198-1.315,P<0.001)were risk factors for prostate cancer. Increased RDW was also a risk factor for prostate cancer in different age subgroups. High RDW level at baseline [hazard ratio(HR)=7.439,95%CI 4.278-21.088,P<0.001] was a risk factor for 3-year overall survival in prostate cancer patients. Conclusions The level of RDW is increased in patients with prostate cancer,which is a risk factor for the development and prognosis of prostate cancer.
