Canadian Association of Radiologists Cancer Diagnostic Imaging Referral Guideline.

Abstract

The Canadian Association of Radiologists (CAR) Cancer Expert Panel is made up of physicians from the disciplines of radiology, medical oncology, surgical oncology, radiation oncology, family medicine/general practitioner oncology, a patient advisor, and an epidemiologist/guideline methodologist. The Expert Panel developed a list of 29 clinical/diagnostic scenarios, of which 16 pointed to other CAR guidelines. A rapid scoping review was undertaken to identify systematically produced referral guidelines that provide recommendations for one or more of the remaining 13 scenarios. Recommendations from 21 guidelines and contextualization criteria in the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) for guidelines framework were used to develop the recommendation for these scenarios. During recommendation formulation, one additional scenario was mapped to an existing CAR guideline scenario, leaving 12 scenarios with new recommendations. The guideline focuses on cancer diagnosis and does not cover cancer staging, follow-up, and surveillance. This guideline presents the methods of development and the referral recommendations for suspected pancreatic cancer, suspected liver cancer, incidental liver mass, incidental colon mass or suspected colon cancer, suspected anal cancer, suspected penile cancer, suspected cervical cancer, suspected endometrial/uterine cancer, suspected vulvar cancer, suspected vaginal cancer, suspected haematologic malignancies, and suspected skin cancer. The guideline also points to other CAR guidelines for suspected neck, thyroid, brain, lung, intracardiac/pericardial, esophageal/gastric, renal, adrenal, bladder, testicular, prostate and ovarian cancers, suspected soft tissue mass or tumour, suspected bone tumour, suspected bone tumour --myeloma, suspected spine tumours, and incidental lung cancer.
