SEER Inquiry System

SINQ is a collection of cancer registry data collection questions and answers. Only designated registrars in SEER registries can submit questions to SINQ. The questions are answered by expert staff and go through a rigorous review process by NCI SEER staff and designated registrars in the SEER registries before being added to SINQ. The review process takes time, so questions submitted to SINQ take longer to answer, sometimes a month or more.

Certain Ask a SEER Registrar questions are added to SINQ to make the information available to the cancer registrar community. These questions go through the same review process as other SINQ questions.

Ask a SEER Registrar

Members of the cancer registrar community may use this form to submit questions to NCI SEER cancer registrars about coding cancer cases or about the materials for registrars distributed through the SEER site. These questions are answered by NCI SEER staff who specialize in the particular topic of the question. Questions are usually answered within 10-15 working days.

Data Collection Answers

The questions and answers are clarifications to existing and historical coding rules. Please see SINQ for the most recent issues.
