  summary: |-
    Background: Adolescents and young adults (AYAs) have distinct cancer survivorship needs. Estimates measured from diagnosis do not reveal whether survival differences across human papillomavirus (HPV)-associated cancer sites persist as patients survive additional years. These patterns could inform survivorship research, risk communication, and care planning.

    Objective: To determine whether differences in five-year conditional relative survival across HPV-associated cancer sites and stages persist, narrow, or widen after patients survive one, three, and five years.

    Approach: The team will conduct a population-based retrospective cohort study using SEER Research Plus Data, 21 Registries. The cohort will include patients aged 15–39 years with a first primary invasive, registry-defined HPV-associated cancer diagnosed during 2000–2013 and followed through December 31, 2023. Established SEER site and histology classifications will define cervical carcinoma, noncervical anogenital squamous cell carcinoma, and oropharyngeal squamous cell carcinoma. Follow-up will extend from diagnosis to death, last contact, or study closure. SEER*Stat will estimate five- and ten-year relative survival and five-year conditional relative survival at diagnosis and among patients surviving one, three, and five years. Absolute differences and relative contrasts will be evaluated across cancer-site groups, harmonized SEER Summary Stage, diagnostic periods, and survival landmarks. Using institutional computing resources, R will support data management and observed-survival analyses with Kaplan–Meier curves, log-rank tests, and multivariable Cox models adjusted for site, stage, age, sex, and diagnostic period. Diagnostics and sensitivity analyses will address proportional hazards, unknown stage, data completeness, and unstable estimates.

    Before the Jamboree, the team will finalize cohort specifications, confirm data access and variables, and assess cell sizes and events. During the Jamboree, the team will implement a reproducible workflow, generate preliminary estimates and visualizations, evaluate limitations, and produce reusable cohort specifications and analysis code. A multidisciplinary team with expertise in epidemiology, biostatistics, HPV-related cancer prevention, and clinical and translational research has been assembled.
