Non-Hospital Cancer Reporting

Ambulatory care facilities, radiation treatment facilities, physician practices and other non-hospital facilities are required to report cases of cancer and precancerous disease to the Oregon State Cancer Registry (OSCaR) electronically.

Reporting process

Review the document on how to report patient cancer diagnosis or treatment to the Oregon Cancer Registry for the process of reporting data to OSCaR.

Practitioner (Physician) Office Reporting

One of the major changes in the healthcare delivery system, and specifically in regard to the cancer patient, is that both diagnosis and treatment are increasingly occurring in non-hospital settings. It is essential that central cancer registries develop mechanisms for collecting cases from non-hospital sources to maintain a complete and accurate count of cancer cases.

All cases of cancer diagnosed or treated by any health care facility or heath care practitioner in Oregon are required to be reported to the Oregon State Cancer Registry (OSCaR). Reporting cancer cases is required by state law. All cancer cases diagnosed on or after January 1, 1996 are required to be reported to OSCaR.


In the current Oregon definition of cancer reporting, Radiologists and/or Radiology Imaging Centers are not considered a healthcare facility. Most radiology testing is performed at the request of a healthcare provider, which makes it the responsibility of the ordering healthcare provider to report the cancer identified from the resulting radiology reports.

Because of the specialized training a Radiologist has, even though your interpretation or professional opinion of the radiology findings may have identified the malignancy or benign brain/CNS, the results are sent back to the ordering healthcare provider and it is their responsibility to report.

Pathology Laboratory Reporting

Pathology laboratories play an integral part of cancer reporting. Any clinical laboratory diagnosing cases of cancer or benign tumors of the brain and central nervous system are required to report each case to the Oregon State Cancer Registry (OSCaR).

All cases of cancer diagnosed or treated by any health care facility or heath care practitioner in Oregon are required to be reported to the Oregon State Cancer Registry (OSCaR). Reporting cancer cases is required by state law. All cancer cases diagnosed on or after January 1, 1996 are required to be reported to OSCaR.

Pathology laboratories wanting to transfer their data electronically should contact the Oregon State Cancer Registry (OSCaR) at oscar.ohd@odhsoha.oregon.gov. OSCaR follows the North American Association of Central Cancer Registries (NAACCR) standards for Pathology Laboratory Electronic Reporting recommendations.
