In this paper, the spectra of tissue sections of cervical inflammation (<jats:italic>n<\/jats:italic>\u00a0=\u200960), CIN (cervical intraepithelial neoplasia) I (<jats:italic>n<\/jats:italic>\u00a0=\u200930), CIN II (<jats:italic>n<\/jats:italic>\u00a0=\u200930), CIN III (<jats:italic>n<\/jats:italic>\u00a0=\u200930), cervical squamous cell carcinoma (<jats:italic>n<\/jats:italic>\u00a0=\u200930), and cervical adenocarcinoma (<jats:italic>n<\/jats:italic>\u00a0=\u200930) were collected by a confocal Raman micro-spectrometer (LabRAM HR Evolution, Horiba France SAS, Villeneuve d\u2019Ascq, France). The Raman spectra of six kinds of cervical tissues were analyzed, the dominant Raman peaks of different kinds of tissues were summarized, and the differences in chemical composition between the six tissue samples were compared. An independent sample <jats:italic>t<\/jats:italic> test (<jats:italic>p<\/jats:italic>\u00a0\u2264\u20090.05) was used to analyze the difference of average relative intensity of Raman spectra of six types of cervical tissues. The difference of relative intensity of Raman spectra of six kinds of tissues can reflect the difference of biochemical components in six kinds of tissues and the characteristic of biochemical components in different kinds of tissues. The classification models of cervical inflammation, CIN I, CIN II, CIN III, cervical squamous cell carcinoma, and cervical adenocarcinoma were established by using a support vector machine (SVM) algorithm. Six types of cervical tissues were classified and identified with an overall diagnostic accuracy of 85.7%. This study laid a foundation for the application of Raman spectroscopy in the clinical diagnosis of cervical precancerous lesions and cervical cancer.<\/jats:p>","DOI":"10.1007\/s10103-020-03218-5","type":"journal-article","created":{"date-parts":[[2021,1,6]],"date-time":"2021-01-06T13:06:18Z","timestamp":1609938378000},"page":"1855-1864","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":41,"title":["Raman spectroscopic study of cervical precancerous lesions and cervical cancer"],"prefix":"10.1007","volume":"36","author":[{"given":"Jing","family":"Wang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cheng-Xia","family":"Zheng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cai-Ling","family":"Ma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiang-Xiang","family":"Zheng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiao-Yi","family":"Lv","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guo-Dong","family":"Lv","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Tang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guo-Hua","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,1,6]]},"reference":[{"key":"3218_CR1","doi-asserted-by":"publisher","first-page":"394","DOI":"10.3322\/caac.21492","volume":"68","author":"F Bray","year":"2018","unstructured":"Bray F, Ferlay J, Soerjomataram I et al (2018) Global cancer statistics 2018: GLOBOCAN estimates of incidence and mortality worldwide for 36 cancers in 185 countries.
