Background: This retrospective study was to establish a prognostic scoring system for patients with non-metastatic head and neck squamous cell carcinoma (HNSCC).
Methods: The medical records of 151 patients with HNSCC were evaluated. Clinical data were collected and statistical analyses were performed to determine the prognostic value of pretreatment variables and to build a risk stratification system. Analysis of the data for 94 additional patients validated the risk stratification system.
Results: Three independent adverse prognostic factors were identified: Age <65 years, LDH ≥ upper normal limit and performance status. The risk stratification was defined as two or more adverse factors presented at diagnosis versus one adverse factor or no adverse factors. Patients with two or more adverse factors had a shorter survival regardless of treatment. This was confirmed in both the training set and the validation set.
Conclusion: This risk stratification provides additional information to the current tumor staging system, which could be useful in making decisions for individual patients and selecting more homogenous patients when designing clinical trials.
