PROLOG is a voluntary, strictly confidential, personal continuing education resource that is designed to be stimulating and enjoyable. By participating in PROLOG, obstetrician–gynecologists will be able to do the following: review and update clinical knowledge; recognize areas of knowledge and practice in which they excel, be stimulated to explore other areas of the specialty, and identify areas requiring further study; plan continuing education activities in light of identified strengths and deficiencies; compare and relate present knowledge and skills with those of other participants; obtain continuing medical education credit, if desired; and have complete personal control of the setting and of the pace of the experience. The obstetrician–gynecologist who completes Gynecologic Oncology and Critical Care, Eighth Edition, will be able to: identify epidemiologic factors that contribute to the risks of various malignancies and determine appropriate screening tests; analyze the pathophysiology and evaluate the histopathology of various malignancies; associate symptoms with early onset of specific malignancies, determine appropriate diagnostic tests, and select diagnosis.
