In order to clarify the predictive role of PNI in the inguinal lymph node (ILN) metastases (ILNM) and oncologic outcome of patients, we performed this meta-analysis and systematic review. The search of PubMed, Embase, and Web of Science was conducted for appropriate studies, up to 20 January 2018. The pooled odds ratio (OR) and hazard ratio (HR) with their 95% confidence interval (CI) were applied to evaluate the difference in ILNM and oncologic outcome between patients present with PNI and those who were absent. A total of 298 in 1001 patients present with PNI were identified in current meta-analysis and systematic review. Significant difference was observed in ILNM between PNI present and absent from patients with PC (OR = 2.98, 95% CI = 2.00\u20134.45). Patients present with PNI had a worse cancer-specific survival (CSS) (HR = 3.58, 95% CI = 1.70\u20137.55) and a higher cancer-specific mortality (CSM) (HR = 2.20, 95% CI = 1.06\u20133.82) than those cases without PNI. This meta-analysis and systematic review demonstrated the predictive role of PNI in ILNM, CSS, and CSM for PC patients.<\/jats:p>","DOI":"10.1042\/bsr20180333","type":"journal-article","created":{"date-parts":[[2018,10,2]],"date-time":"2018-10-02T12:45:23Z","timestamp":1538484323000},"update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["The role of perineural invasion in penile cancer: a meta-analysis and systematic review"],"prefix":"10.1042","volume":"38","author":[{"given":"Xiang","family":"Zhou","sequence":"first","affiliation":[{"name":"Department of Urology, First Affiliated Hospital of Nanjing Medical University, No. 300, Guangzhou Street, Nanjing, Jiangsu Province 210029, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feng","family":"Qi","sequence":"additional","affiliation":[{"name":"Department of Urology, First Affiliated Hospital of Nanjing Medical University, No. 300, Guangzhou Street, Nanjing, Jiangsu Province 210029, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ruhua","family":"Zhou","sequence":"additional","affiliation":[{"name":"College of Nursing, Nanjing Medical University, No. 101, Longmian Street, Nanjing, Jiangsu Province 210029, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shangqian","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Urology, First Affiliated Hospital of Nanjing Medical University, No. 300, Guangzhou Street, Nanjing, Jiangsu Province 210029, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yamin","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Urology, First Affiliated Hospital of Nanjing Medical University, No. 300, Guangzhou Street, Nanjing, Jiangsu Province 210029, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Urology, First Affiliated Hospital of Nanjing Medical University, No. 300, Guangzhou Street, Nanjing, Jiangsu Province 210029, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chen","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Urology, First Affiliated Hospital of Nanjing Medical University, No. 300, Guangzhou Street, Nanjing, Jiangsu Province 210029, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yichun","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Urology, First Affiliated Hospital of Nanjing Medical University, No. 300, Guangzhou Street, Nanjing, Jiangsu Province 210029, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Urology, First Affiliated Hospital of Nanjing Medical University, No. 300, Guangzhou Street, Nanjing, Jiangsu Province 210029, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ninghong","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Urology, First Affiliated Hospital of Nanjing Medical University, No. 300, Guangzhou Street, Nanjing, Jiangsu Province 210029, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"288","published-online":{"date-parts":[[2018,10,31]]},"reference":[{"key":"2021111619141579100_B1","doi-asserted-by":"publisher","first-page":"7","DOI":"10.3322\/caac.21332","article-title":"Cancer statistics, 2017","volume":"66","author":"Siegel","year":"2017","journal-title":"CA Cancer J.
