Welcome to the Patterns of Care (POC) Explorer Website

POC is an initiative to evaluate dissemination of state-of-the-art cancer therapy and diagnostics into community oncology practice and identify factors associated with cancer care. Data for POC studies are collected from a stratified random sample of eligible SEER cases. More information is available on the POC homepage.

POC*Explorer is an interactive website allowing access to aggregate data from certain POC studies.

What's Included in the Current Release?

POC*Explorer presents aggregated data for selected cancer sites across several topics of the Patterns of Care studies. Each cancer site study collected data from stratified random samples of eligible SEER cases for individuals diagnosed in the study year. Cases from individuals who were African American/Black, American Indian/Alaskan Native, Asian/Pacific Islander, and/or Hispanic were oversampled.

What Will Future Releases Include?

Future releases of POC*Explorer will include data from other cancer sites listed on the POC website. We also plan to include other variables that were collected as part of POC studies, such as certain comorbidities, and variables that can be linked between POC and SEER, such as urban/rural residency.

How Can I Provide Feedback, Including Suggestions for Future Updates to POC*Explorer?
