Forty-eight patients (25 supraglottic, 23 glottic) who had undergone operations between 1998 and 2003 were included in this study. The Envision immunohistochemistry method was utilized to stain these tissue specimens. The results showed that the immunostaining of p21<jats:sup>WAF1\/Cip1<\/jats:sup> do not show any correlation with differentiation, N stage, metastasis, survival, recurrence or the laryngeal site of involvement. A significant inverse correlation was detected between p21<jats:sup>WAF1\/Cip1<\/jats:sup> and the T stage. In contrast, the percentage of PCNA labelled cells showed a significant correlation with the T stage, but not with other clinicopathological parameters. There were differences in the expression of p21<jats:sup>WAF1\/Cip1<\/jats:sup> and PCNA between the supraglottic and the glottic carcinomas. In conclusion, our findings suggest that p21<jats:sup>WAF1\/Cip1<\/jats:sup> and PCNA may play an important role in the progression of carcinoma of the supraglottic larynx.<\/jats:p>","DOI":"10.1017\/s0022215106002726","type":"journal-article","created":{"date-parts":[[2006,9,25]],"date-time":"2006-09-25T10:44:13Z","timestamp":1159181053000},"page":"1042-1048","source":"Crossref","is-referenced-by-count":5,"title":["The immunohistochemical expression of p21<sup>WAF1\/Cip1<\/sup> and Proliferating cell nuclear antigen in laryngeal squamous cell carcinomas"],"prefix":"10.1017","volume":"120","author":[{"given":"X","family":"Li","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S","family":"Izumaru","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K","family":"Sakamoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y","family":"Miyajima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T","family":"Nakashima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2006,9,25]]},"container-title":["The Journal of Laryngology &amp; Otology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0022215106002726","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,2]],"date-time":"2019-05-02T19:30:00Z","timestamp":1556825400000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0022215106002726\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2006,9,25]]},"references-count":0,"journal-issue":{"issue":"12","published-print":{"date-parts":[[2006,12]]}},"alternative-id":["S0022215106002726"],"URL":"https:\/\/doi.org\/10.1017\/s0022215106002726","relation":{},"ISSN":["0022-2151","1748-5460"],"issn-type":[{"value":"0022-2151","type":"print"},{"value":"1748-5460","type":"electronic"}],"subject":[],"published":{"date-parts":[[2006,9,25]]}}}
