BACKGROUND: : The authors propose a prognostic score model using a prospective study of patients with regional metastatic cutaneous squamous cell carcinoma of the head and neck. METHODS: : Two-hundred fifty patients were analyzed using a competing risks model to identify risk factors for survival. A risk score was obtained using the significant coefficients from the regression model, and cutoff points were determined that separated the score into 3 risk groups (low risk, moderate risk, and high risk). RESULTS: : At a median follow-up of 54 months (range, 1.3-212 months) 70 of 250 patients (28%) developed recurrent disease: Most were regional recurrences (51 of 70 patients; 73%) in the treated lymph node basin. After regional recurrence, a majority (73%) died of disease. The following 4 variables were associated significantly with survival: immunosuppression (hazard ratio [HR], 3.13; 95% confidence interval [CI], 1.39-7.05), treatment (HR, 0.32; 95% CI, 0.16-0.66), extranodal spread (HR, 9.92; 95% CI, 1.28-77.09), and margin status (HR, 1.85; 95% CI, 1.85-3.369); and those 4 variables (immuosuppression, treatment, extranodal spread, and margin status) were used to calculate the ITEM score. The 5-year risk of dying from disease for patients with high-risk (>3.0), moderate-risk (>2.6-3.0), and low-risk (< or =2.6) ITEM scores were 56%, 24%, and 6%, respectively. Fifty-six of 250 patients (22%) died from another cause. CONCLUSIONS: : Patients who underwent surgery and received adjuvant radiotherapy had a better outcome compared with patients who underwent surgery alone. Patients who had moderate- or high-risk ITEM scores, usually because of extranodal spread and involved excision margins, had a poor outcome. The authors recommend considering these patients for inclusion in adjuvant chemoradiotherapy trials. Cancer 2009. (c) 2009 American Cancer Society.
