This study analyzed the prognostic value of clinical variables (age, sex, tumor site, stage) and biologic parameters (squamous cell carcinoma antigen [SCC], serum thymidine kinase activity [TK], fibrin, sedimentation rate [SR]) at the time of diagnosis of squamous cell carcinoma of the head and neck (oral cavity, oropharynx, hypopharynx) in 189 patients. Among the clinical variables investigated, UICC stage III\u2013IV disease (<jats:italic>p<\/jats:italic> &lt; .0002), a hypopharyngeal site (<jats:italic>p<\/jats:italic> &lt; .02), and age over 60 years (<jats:italic>p<\/jats:italic> &lt; .01) were all associated with a poor prognosis. Similarly, analysis of biological blood variables allowed definition of cut\u2010off values above which the prognosis was poor: SCC 2.5 ng\/mL (<jats:italic>p<\/jats:italic> &lt; .01), fibrin 3.5 g\/L (<jats:italic>p<\/jats:italic> &lt; .01), TK 7 IU\/L (<jats:italic>p<\/jats:italic> &lt; .0005), and SR 15 mm per first hour (<jats:italic>p<\/jats:italic> &lt; .0000). Cox regression analysis of overall survival identified the UICC stage (<jats:italic>p<\/jats:italic> &lt; .000), the SR (<jats:italic>p<\/jats:italic> &lt; .001), and serum TK (<jats:italic>p<\/jats:italic> &lt; .02) as the main independent prognostic factors. A separate study on a small number of head and neck cancer patients revealed higher TK levels in malignant squamous cell carcinoma tissue than in adjacent healthy tissue.<\/jats:p>","DOI":"10.1002\/hed.2880150510","type":"journal-article","created":{"date-parts":[[2007,2,21]],"date-time":"2007-02-21T22:10:47Z","timestamp":1172095847000},"page":"425-432","source":"Crossref","is-referenced-by-count":5,"title":["Sedimentation rate and serum thymidine kinase activity: Prognostic factors in squamous cell head and neck cancer"],"prefix":"10.1002","volume":"15","author":[{"given":"Xavier","family":"Fontana","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olivier","family":"Dassonville","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jo\u00ebl","family":"N\u00e9ri","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacques","family":"Vallicioni","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9","family":"Santini","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G\u00e9Rard","family":"Milano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre","family":"Combon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fran\u00e7oise","family":"Lapalus","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fran\u00e7ois","family":"Demard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2006,7,18]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"3","article-title":"The prognostic relevance of various factors at the time of the first admission of the patient","volume":"11","author":"Platz H","year":"1983","journal-title":"J Oral Maxillofac Surg"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/hed.2880120107"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19911101)68:9<1994::AID-CNCR2820680925>3.0.CO;2-I"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9610(89)90014-7"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/hed.2880110508"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1002\/hed.2880120105"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9610(89)90123-2"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19881101)62:9<1932::AID-CNCR2820620911>3.0.CO;2-A"},{"key":"e_1_2_1_10_2","first-page":"781","article-title":"Int\u00e9r\u00e9t diagnostique du dosage du SCC\u2010TA4 dans quatre localisations de cancers \u00e9pidermo\u00efdes.
