Criteria for a Positive Screening Examination and Classification of Diagnostic Follow-Up Procedures
Diagnostic Follow-Up Procedures | ||||
---|---|---|---|---|
Screening Modality | Definition of a Positive Screening Result | Minimally Invasive Procedures | Moderately Invasive Procedures | Major Surgical Procedures |
CA-125 = cancer antigen 125; CXR = chest radiograph; DRE = digital rectal examination; FSG = flexible sigmoidoscopy; PSA = prostate-specific antigen; TVU = transvaginal ultrasonography. | ||||
a Assuming a perfect sphere and using the prolate ellipsoid formula, this volume correlates to an approximate diameter of 2.67 cm. A 10-cc cutoff was chosen, as it corresponds to 2 standard deviations above mean ovarian volume for postmenopausal women.24 | ||||
b We define a true-positive FSG as both overt cancer and advanced adenomas (lesions with villous histologic findings, severe cellular dysplasia, and/or ≥1 cm in diameter). | ||||
