Correlation of clinical features and different clinical stages with body mass index in patients of prostate cancer

Objective To retrospectively analyze the different clinical stages of patients with prostate cancer, and to investigate it’s correlation with body mass index (BMI). Methods 363 patients with prostate cancer were enrolled from January 2008 to December 2016. There were 141 cases of stage Ⅱ, Ⅲ in 20 cases, 202 cases of stage Ⅳ. According to the stratification of BMI(emaciation group, normal group, overweight group, obesity group), clinical data of different groups of prostate cancer patients were compared to analyze there correlation with BMI. Results Patient's age, pre-PSA concentration, Gleason scores and PSA density were significantly correlated with clinical stage (P<0.05). Prostate volume and weight had no significant correlation with staging. There was a significant correlation between different strata of BMI and clinical stage (P<0.05). Conclusion The different strata of BMI are closely related to the clinical stage. The higher BMI, the higher risk of the prostate cancer.
