OBJECTIVE: The objective of this study is to identify valuable prognostic factors, build clinical prediction nomograms, and recommend the optimal therapeutic strategy for patients with initially diagnosed glottic cancer.
METHODS: Patients were extracted from the SEER database. Cox regression analyses, survival analyses, an internal validation, the propensity score analysis, and the competing risk analysis were performed.
RESULTS: Nine overlapped factors were considered as valuable prognostic factors. Furthermore, nomograms were established for clinical prediction models to assess the 1-, 3-, and 5-year overall survival (OS) and cancer-specific survival (CSS). C-indexes, receiver operating characteristic curves, calibration curves, and decision curve analyses proved that nomograms showed better predictive accuracy, ability, and prognostic value compared to the American Joint Committee on Cancer stage. For patients in stage I, primary site surgery alone would acquire best OS and CSS. For patients in stage II, primary site surgery and/or radiation would gain better OS and CSS. For patients in stage III, radiation plus chemotherapy or primary site surgery (alone or plus radiation) would acquire better OS and CSS. Moreover, for patients in stage IV, primary site surgery plus radiation would gain better OS and CSS.
CONCLUSIONS: Nomograms could be useful for patients' counseling and guide therapeutic decision-making. Primary site surgery alone may likely be the optimal therapy for stage I glottic cancer, and primary site surgery and/or radiation may be the recommended therapy for stage II glottic cancer. The combination treatment would be the preferred choice for advanced-stage (stage III & IV) glottic cancer, and the role of chemotherapy needs to be further explored.
