Journal ArticleDOI
Identification of a subpopulation of cells with cancer stem cell properties in head and neck squamous cell carcinoma
Mark E. Prince,Ranjiv Sivanandan,Andrew J. Kaczorowski,Gregory T. Wolf,Michael J. Kaplan,Piero Dalerba,Irving L. Weissman,Michael F. Clarke,Laurie Ailles +8 more
TL;DR: Data demonstrate that cells within the CD44+ population of human HNSCC possess the unique properties of cancer stem cells in functional assays for cancer stem cell self-renewal and differentiation and form unique histological microdomains that may aid in cancer diagnosis.
Journal ArticleDOI
Randomized trial comparing surgery and adjuvant radiotherapy versus concurrent chemoradiotherapy in patients with advanced, nonmetastatic squamous cell carcinoma of the head and neck: 10‐year update and subset analysis
N. Gopalakrishna Iyer,Daniel Shao-Weng Tan,Veronique Kiak Mien Tan,Weining Wang,Jacqueline S.G. Hwang,Ngian-Chye Tan,Ranjiv Sivanandan,Hiang Khoon Tan,Wan-Teck Lim,Mei-Kim Ang,Joseph Wee,Khee Chee Soo,Eng Huat Tan +12 more
TL;DR: The current study was performed to report the long‐term results of a trial comparing concurrent chemotherapy and radiotherapy with surgery and adjuvant radiotherapy in patients with stage III/IV nonmetastatic head and neck squamous cell carcinoma.
Journal ArticleDOI
Detection of neoplasms in the oral cavity by digitized endoscopic imaging of 5-aminolevulinic acid-induced protoporphyrin IX fluorescence.
TL;DR: Initial results indicate that the digitized endoscopic imaging system combined with the fluorescence image quantification method and the ratio diagnostic algorithm developed in this study has the potential to significantly improve the non-invasive diagnosis of early oral neoplasms in vivo.
Journal ArticleDOI
Detection of squamous cell carcinomas and pre-cancerous lesions in the oral cavity by quantification of 5-aminolevulinic acid induced fluorescence endoscopic images
TL;DR: The applicability of quantifying PPIX fluorescence images to improve the diagnostic specificity and detect early oral lesions is explored.
Journal ArticleDOI
Long-term Results of 100 Consecutive Comprehensive Neck Dissections: Implications for Selective Neck Dissections
Ranjiv Sivanandan,Michael J. Kaplan,Kimberly J. Lee,Darren R. Lebl,Harlan A. Pinto,Quyhn-Thu Le,Don R. Goffinet,Willard E. Fee +7 more
TL;DR: The long-term local recurrence rates in 100 consecutive patients undergoing a radical or modified radical neck dissection for clinically positive (N+) and N0 neck disease are reported and comprehensively the literature reporting and comparing regional control rates for both neck dissections types are reviewed.
