To accentuate the efficacy of grouping, Groups 1\u20136 underwent clustered analysis of hazard atio (HR) values pertaining to progression\u2010free survival (PFS), forming three risk clusters denoted as low, intermediate, and high. The log\u2010rank test was employed to discern differences, and R 4.1.1 was utilized for cluster analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>According to survival rates, we classified the first (G2 and G4), second (G1 and G6), and third (G3 and G5) risk clusters as low\u2010, intermediate\u2010, and high\u2010risk, respectively. When comparing risk stratification with the 8th edition of the TNM staging system, our classification exhibited superior predictive prognostic performance. Subgroup analysis of treatments for each risk cluster revealed that the PFS in the neoadjuvant chemotherapy (NACT)\u2009+\u2009concurrent chemoradiotherapy (CCRT) group surpassed that of the CCRT group significantly (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The reliance on clinical types and TVRR facilitates risk stratification of NPC during chemoradiotherapy, providing a foundation for physicians to tailor therapeutic strategies. Moreover, the risk cluster delineated for NPC patients during the mid\u2010term of chemoradiotherapy stands as an independent prognostic factor for progression\u2010free survival (PFS), overall survival (OS), distantmetastasis\u2010free survival (DMFS), and local recurrence\u2010free (LRRFS) posttreatment. Additionally, individuals in the high\u2010risk cluster are recommended to undergo adjuvant chemotherapy after CCRT.<\/jats:p><\/jats:sec>","DOI":"10.1002\/cam4.7029","type":"journal-article","created":{"date-parts":[[2024,2,24]],"date-time":"2024-02-24T05:46:02Z","timestamp":1708753562000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Risk stratification of <scp>LA<\/scp>\u2010<scp>NPC<\/scp> during chemoradiotherapy based on clinical classification and <scp>TVRR<\/scp>"],"prefix":"10.1002","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-5835-2081","authenticated-orcid":false,"given":"Qianlong","family":"Tang","sequence":"first","affiliation":[{"name":"Department of Radiation Oncology, Radiation Oncology Key Laboratory of Sichuan Province Sichuan Clinical Research Center for Cancer, Sichuan Cancer Hospital &amp; Institute, Sichuan Cancer Center, Afffliated Cancer Hospital of University of Electronic Science and Technology of China  Chengdu China"},{"name":"Department of Oncology Sichuan Mianyang 404 Hospital, First People's Hospital of Mianyang  Mianyang China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chaorong","family":"Mei","sequence":"additional","affiliation":[{"name":"Hospital of Chengdu Office of People's Government of Tibetan Autonomous Region (Hospital.C.T.)
