Description:Background:
Although survival has improved dramatically for most adolescents and young adults (AYAs, 15–39 years old) with cancer, it remains poor for those presenting with metastatic disease. To better characterize this subset, we conducted a landscape survival comparison with older adults (OAs, 40–79 years).
Methods:
Using Surveillance, Epidemiology, and End Results Program data from 2000–2016, we examined incident cases of poor-prognosis metastatic cancers (5-year survival < 50%) among AYAs (n=11,518) and OAs (n=345,681) and compared cause-specific survival by sociodemographic characteristics (race/ethnicity, sex, and socioeconomic status). Adjusted hazard ratios (aHRs) for death from metastatic disease (95% confidence intervals [95%CI]) were compared between AYAs and OAs (pint).
Results:
AYAs had significantly better survival than OAs for every cancer site except kidney, where it was equivalent (range of aHRs: 0.91 [95%CI 0.82–1.02] for kidney cancer to 0.33 [0.26–0.42] for rhabdomyosarcoma). Compared to their OA counterparts, greater survival disparities existed for AYAs who were non-Hispanic Black with uterine cancer (aHR=2.20 [1.25–3.86] versus 1.40 [1.28–1.54]; pint=0.049) and kidney cancer (aHR=1.51 [1.15–1.98] versus 1.10 [1.03–1.17]; pint=0.04); non-Hispanic Asian/Pacific Islanders with ovarian cancer (aHR=1.47 [1.12–1.93] versus 0.89 [0.84–0.95], pint<0.001); and males with colorectal cancer (aHR=1.21 [1.10–1.32] versus 1.08 [1.06–1.10]; pint=0.045)).
Conclusions:
AYAs diagnosed with these metastatic cancers have better survival than OAs, but outcomes remain dismal.
Impact:
Overcoming the impact of metastasis in these cancers is necessary for continuing progress in AYA oncology. Sociodemographic disparities affecting AYAs within kidney, uterine, ovarian, and colorectal cancer could indicate plausible effects of biology, environment, and/or access and should be explored.
