Abstract
BackgroundProstate cancer is one of the most common non-cutaneous malignancies in men. We aimed to systemically evaluate the relationship between the expression of CD147 in tissues and the clinicopathological features of prostate cancer.Methods and FindingsPubMed (1966–2016), EMBASE (1980–2016), the Cochrane Library (1996–2016), Web of Science (1945–2016), China National Knowledge Infrastructure (1982–2016), and the WanFang databases (1988–2016) were searched. Literature quality assessment was performed with the Newcastle-Ottawa Scale. Meta-analysis was performed by using Review Manager 5.3 and Stata 13.0. A total of 12591 prostate cancer patients from 14 studies were included. The results of the meta-analysis showed that there were significant differences in the positive expression rate in the following comparisons: prostatic cancer tissues vs. normal prostate tissues (odds ratio [OR] = 26.93, 95% confidence interval [CI] 7.95–91.20, P < 0.00001), prostatic cancer tissues vs. benign prostatic hyperplasia tissues (OR = 20.54, 95% CI 8.20–51.44, P < 0.00001), high Gleason score vs. low Gleason score (OR = 2.39, 95% CI 1.33–4.27, P = 0.03), TNM III to IV vs. TNM I to II (OR = 9.95, 95% CI 4.96–19.96, P < 0.00001), low or moderate differentiation vs. high differentiation (OR = 8.12, 95% CI 3.69–17.85, P < 0.00001), lymph node metastasis vs. non-lymph node metastasis (OR = 4.31, 95% CI 1.11–16.71, P = 0.03), and distant metastasis vs. non-distant metastasis (OR = 8.90, 95% CI 3.24–24.42, P < 0.00001).ConclusionThe CD147 positive expression rate was closely related to the clinical characteristics of prostate cancer, but more research is needed to confirm the findings owing to the results of the subgroups.
Highlights
The incidence of prostate cancer is the second highest among all malignant tumors in men, and it is the most common cancer in men in developed countries [1]

For the country subgroup analysis, only the results of the Gleason score model may be changed because of the area the study was conducted in
Summary
The incidence of prostate cancer is the second highest among all malignant tumors in men, and it is the most common cancer in men in developed countries [1]. The incidence of prostate cancer in developing countries is lower than in developed countries, it has shown a continuous rapid increase in recent years[2]. Prostate cancer prognosis varies significantly among patients according to clinical stage and pathological grade. PSA will increase in most clinically significant cases of prostate cancer. We hoped to find a more effective index that has a close relationship with the clinical features of prostate cancer[4]. Prostate cancer is one of the most common non-cutaneous malignancies in men. We aimed to systemically evaluate the relationship between the expression of CD147 in tissues and the clinicopathological features of prostate cancer.
