| Description: |
AbstractBackground: Survival studies on head and neck cancers are frequently reported with inadequate account for competing causes of death. Realistic descriptions and predictions of postdiagnosis mortality should be based on proper competing risks methodology. Methods: Prognosis of patients with oral squamous cell carcinoma (OSCC) in terms of mortality from OSCC and from other causes, respectively, was analyzed according to recent methodological recommendations using cumulative incidence functions and models for cause‐specific hazards and subdistribution hazards in 306 patients treated in a tertiary care center in Northern Finland. Results: More coherent and informative descriptions and predictions of mortality by cause were obtained with state‐of‐the‐art statistical methods for competing risks than using the prevalent but questionable practice to graph “disease‐specific survival.” Conclusion: From the patients’ perspective, proper competing risks analysis offers more relevant prognostic scenarios than na€ıve analyses of “disease-specific survival”; therefore, it should be used in prognostic studies of head and neck cancers. see all
