OBJECTIVE/HYPOTHESIS: Infection with the hepatitis C virus (HCV) is a global problem with over 170 million people infected. Recently, we have noticed that a large number of patients diagnosed with squamous cell carcinoma of the head and neck (SCCHN) have also been diagnosed with HCV. A review of the literature reveals little information concerning this patient population. The objective of this study was to compare the outcome of SCCHN patients who have been exposed to HCV with naïve SCCHN patients. STUDY DESIGN: Retrospective chart review. METHODS: A retrospective chart review from June 1991 through December 2002 was performed to identify patients diagnosed with SCCHN who were screened for HCV. Patients were stratified into two groups (HCV positive and HCV negative). Data were recorded on patients for status of disease at last clinic visit, pretreatment serum albumin and hematocrit levels, and RNA quantities of HCV. Statistical analysis was performed using paired t test to compare serum albumin and hematocrit levels. Kaplan-Meier survival curves were used to compare outcomes. The log-rank test was used to determine significance. Cox regression was used to examine the association of prognostic predictor variables with overall survival and disease-free survival. RESULTS: There was no difference noted in 5 year survival between hepatitis C positive and hepatitis C negative groups in overall outcomes (66.7% vs. 67.9%, P = 1.000) or 5 year disease-free survival (90.5% vs. 80.8%, P = .514). The two groups, HCV positive versus HCV negative, also had similar serum albumin levels (3.62 g/dL vs. 3.72 g/dL, P = .37) as well as serum hematocrit levels (42.9% vs. 41.0%, P = .12). Serum levels of hepatitis C RNA were obtained in seven patients, with only one being undetectable. The only prognostic predictor variable that was significantly associated with overall survival was age. None of the predictor variables were significantly associated with disease-free survival. CONCLUSION: Co-infection with HCV, although prevalent in the Veterans Administration Hospital population, did not affect patient outcome as defined by disease-free survival. Patients who were seropositive for HCV had comparable serum albumin levels as well as serum hematocrit when compared with HCV negative patients.
