OBJECTIVE: We aimed to compare the prognosis of laryngeal squamous cell carcinoma (LSCC) and nSCCs of the larynx.Then we established a nomogram for nSCCs of the larynx.
METHODS: Prognosis between the 529 pairs nSCCs of the larynx patients and LSCC patients were compared after propensity score matching (PSM). 591 nSCCs of the larynx patients were divided into the modeling and validation groups. Univariate and multivariate Cox analyses obtain independent prognostic factors, which were then included in the nomogram to predict the 3 and 5 year survival. Prognostic accuracy of the nomogram was evaluated using the consistency index (C-index) and the calibration curve.
RESULTS: Prognosis of nSCCs of the larynx was poorer than LSCC. Age, race, tumor location, tumor-node-metastasis stage, and method were independent prognostic factors of nSCCs of the larynx (P < 0.05). Internal and external validation proves the nomogram reliable CONCLUSION: The nomogram showed good prognostic accuracy and would assist clinicians in making more accurate evaluations for patients.
