Background

Head and neck cancer patients have a higher risk of developing a second primary malignancy (SPM) than the general population. This study was conducted to identify the characteristics of SPM and its impact on survival in patients with squamous cell carcinoma of the tongue (TSCC) and larynx (LSCC).

Methods

A retrospective study was conducted of 538 patients who were treated by surgery primarily for TSCC (n = 146) and LSCC (n = 392) from 1990 to 2000. The incidence, site, and overall survival of SPMs were evaluated.

Results

Seventy-seven patients developed SPM during the follow-up period (median, 73 months), including 18 (12%) with TSCC and 59 (15%) with LSCC. Fifty-six percent of SPMs of the TSCC group appeared in the oral cavity. Among the SPMs of LSCC patients, 54% developed in the lung (31%) and larynx (24%). The 5-year overall survival after the diagnosis of SPM in the head and neck was 39%, compared to 29% for SPM in other areas (p = 0.010).

Conclusion

SPMs after treatment of TSCC and LSCC are similar in incidence but distinct in pattern. SPMs within the head and neck are associated with a better prognosis than those outside this area.
