Abstract

OBJECTIVES: To estimate the cumulative percentage of second primary tumors (SPTs) in head and neck (H&N) cancer patients and primary cancers in general Nicotine Dependence Center (NDC) population controls following tobacco dependence consultation seen between 1988 and 2001. METHODS: A 1:1 matched pair design and a stratified Cox proportional hazard model were used. General NDC population controls were matched on age, gender, and NDC consult (type and date) to the H&N cancer patients. The study population included 101 H&N cancer patients (66 male, 35 female) with mean (SD) age of 58.7 (10.1) years. RESULTS: Baseline demographics and length of follow-up were similar between groups. However, H&N cancer patients smoked more cigarettes per day than controls (P < 0.003). For H&N cancer patients, the median time from initial H&N cancer diagnosis to NDC consult was 7 months (range, 0-292 months). Following the NDC consult, 27 H&N cancer patients developed 32 SPTs; whereas among the controls, 12 patients developed 12 other cancers (P = 0.013). There was no difference in the development of non-tobacco-related cancers (P = 0.273). However, H&N cancer patients were more likely to develop tobacco-related cancers (P = 0.01). Furthermore, there was a trend where the H&N cancer patients who continued to use tobacco were more likely to develop tobacco-related cancers than those who remained abstinent (P = 0.10). CONCLUSIONS: These findings confirm that H&N cancer patients are more prone to the development of tobacco-related cancers. Further, these findings suggest that H&N cancer patients who stop using tobacco are able to decrease the development of tobacco-related SPTs.
