We acquired reflectance, fluorescence, and Raman spectra from 137 lesions in 76 patients using custom-built optical fiber-based clinical systems. Biopsies of lesions were classified using standard histopathology as malignant melanoma (MM), nonmelanoma pigmented lesion (PL), basal cell carcinoma (BCC), actinic keratosis (AK), and squamous cell carcinoma (SCC). Spectral data were analyzed using principal component analysis. Using multiple diagnostically relevant principal components, we built leave-one-out logistic regression classifiers. Classification results were compared with histopathology of the lesion. Sensitivity\/specificity for classifying MM versus PL (12 versus 17 lesions) was 100%\/100%, for SCC and BCC versus AK (57 versus 14 lesions) was 95%\/71%, and for AK and SCC and BCC versus normal skin (71 versus 71 lesions) was 90%\/85%. The best classification for nonmelanoma skin cancers required multiple modalities; however, the best melanoma classification occurred with Raman spectroscopy alone. The high diagnostic accuracy for classifying both melanoma and nonmelanoma skin cancer lesions demonstrates the potential for SD as a clinical diagnostic device.<\/jats:p>","DOI":"10.1117\/1.jbo.19.11.117003","type":"journal-article","created":{"date-parts":[[2014,11,6]],"date-time":"2014-11-06T12:30:32Z","timestamp":1415277032000},"page":"1-12","source":"Crossref","is-referenced-by-count":105,"title":["Clinical study of noninvasive in vivo melanoma and nonmelanoma skin cancers using multimodal spectral diagnosis"],"prefix":"10.1117","volume":"19","author":[{"given":"Liang","family":"Lim","sequence":"first","affiliation":[{"name":"The Univ. of Texas at Austin"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brandon S.","family":"Nichols","sequence":"additional","affiliation":[{"name":"The Univ. of Texas at Austin"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael R.","family":"Migden","sequence":"additional","affiliation":[{"name":"The Univ. of Texas M.D. Anderson Cancer Ctr."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1224-8567","authenticated-orcid":false,"given":"Narasimhan","family":"Rajaram","sequence":"additional","affiliation":[{"name":"The Univ. of Texas at Austin"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-0987-0646","authenticated-orcid":false,"given":"Jason","family":"Reichenberg","sequence":"additional","affiliation":[{"name":"The Univ. of Texas at Austin"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mia K.","family":"Markey","sequence":"additional","affiliation":[{"name":"The Univ. of Texas at Austin"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Merrick I.","family":"Ross","sequence":"additional","affiliation":[{"name":"The Univ. of Texas M.D. Anderson Cancer Ctr."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James W.","family":"Tunnell","sequence":"additional","affiliation":[{"name":"The Univ. of Texas at Austin"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"189","container-title":["Journal of Biomedical Optics"],"original-title":[],"link":[{"URL":"https:\/\/www.spiedigitallibrary.org\/journals\/journal-of-biomedical-optics\/volume-19\/issue-11\/117003\/Clinical-study-of-noninvasive-in-vivo-melanoma-and-nonmelanoma-skin\/10.1117\/1.JBO.19.11.117003.full","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,1]],"date-time":"2026-10-01T01:03:11Z","timestamp":1790816591000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.spiedigitallibrary.org\/journals\/journal-of-biomedical-optics\/volume-19\/issue-11\/117003\/Clinical-study-of-noninvasive-in-vivo-melanoma-and-nonmelanoma-skin\/10.1117\/1.JBO.19.11.117003.full"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,11,6]]},"references-count":0,"journal-issue":{"issue":"11"},"URL":"https:\/\/doi.org\/10.1117\/1.jbo.19.11.117003","relation":{},"ISSN":["1083-3668","1560-2281"],"issn-type":[{"value":"1083-3668","type":"print"},{"value":"1560-2281","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,11,6]]}}}
