A matched survival analysis for squamous cell carcinoma of the head and neck in the elderly. 
To determine whether elderly patients manifest poorer survivals for head and neck squamous cell carcinoma.  Cases of squamous cell carcinoma of the glottic larynx, oral tongue, and tonsil were extracted from the Surveillance, Epidemiology and End Results database for 1988 to 1998.  For each primary site, patients were segregated into two age groups: 50 to 69 years of age and 70 years of age and older.  For each case in the latter, elderly group, a reference group case was randomly matched for gender, year of diagnosis, cancer stage, extent of surgery, and radiation therapy.  Overall survival and disease-specific survival were compared between the two groups with stage stratification with the Kaplan-Meier method.  Cases of glottic carcinoma (1882), tongue carcinoma (426), and tonsillar carcinoma (200) in elderly patients were matched to the reference group.  Overall mean survival differences were significant for glottic carcinoma (73.9 vs. 96.7 mo, elderly and younger groups, respectively) (P <.001) and tongue carcinoma (59.5 vs. 73.1 mo) ( P=.002) but not for tonsillar carcinoma (46.0 vs. 54.4 mo) ( P=.220).  Disease-specific survival differences were significant but small in magnitude for glottic carcinoma (105.9 vs. 114.1 mo, respectively (P <.001) and tongue carcinoma (81.6 vs. 93.6 mo) (P =.009) but not for tonsillar carcinoma (71.5 vs. 70.7 mo) (P =.422).  However, after stage stratification, elderly patients often did not exhibit statistically or practically significant poorer overall or disease-specific survivals.  Elderly patients do not necessarily exhibit clinically significant poorer survivals for head and neck squamous cell carcinoma.  Age alone should not be used to determine treatment options for elderly patients with squamous cell carcinoma.
