Figure 3. Age-adjusted Incidence rates among women for oropharynx squamous cell cancer by age (Figure 3A) and race/ethnicity (Figure 3B) and for non-oropharynx head and neck squamous cell cancer by race/ethnicity (Figure 3C).

Figure 3

Incidence on y-axis (per 100,000) and year of diagnosis on x-axis. In Figure 3A, in zero joinpoint model non-significant changes were seen for ages 40-49, 50-59, and 80+ (p>0.147 for each). Significant decreases in incidence were observed for OPSCC among 60-69 (APC -1.3, p=0.003) and 70-79 (APC -1.1, p=0.005). In Figure 3B. Selected joinpoint model incidence rates during 1992-2014 are shown for Whites in blue (p=0.4) and Blacks (APC-1.8, p=0.006) in orange. In Figure 3C, incidence for non-OP HNSCC is depicted using zero joinpoint model during 1992-2014. Significant declines in incidence are shown for Whites in blue (APC -1.0, p<0.001), Blacks in red (APC -3.0, p<0.001), Hispanics in green (APC -1.1, p=0.016) and Asians in grey (APC -0.9, p=0.025). Incidence rates are age-adjusted to the 2000 US Standard Population (19 age groups – Census P25-1130).
