Once adenomatous polyps are detected, the person exits the model.
When test results were positive, a follow-up colonoscopy was assumed regardless of the polyp size.
Her past medical history included hypercholesterolaemia, hypothyroidism (partial thyroidectomy), and surgery for a benign ovarian tumor and uterine polyps some 38 years ago.
This study particularly addressed this issue, using a disease model that captured the uncertainty associated with polyp dwell time.
The length of time in surveillance and the frequency of tests depended upon the size and type of polyp (38).
As demonstrated by sensitivity analyses, the dynamics of polyp-cancer transition have significant effect upon the magnitude of the cost:effectiveness ratios.
At-risk relatives exit the model when adenomatous polyps are identified.
Persons who were found to have polyps underwent transition to a surveillance group after polyps were removed.
For adenomatous and hyperplastic polyps, initial probabilities were estimated to be 25% and 5%, respectively (34;38).
Early detection of polyps and cancer can also reduce eventual treatment costs.
The assumption made for polyp dwell time critically affected the attractiveness of alternative screening strategies.
The effectiveness of screening average-risk persons is derived from early detection of cancer and removal of polyps, lowering the incidence of cancer and cancer-related deaths.
Measures of test sensitivity, which varied by polyp size, and test specificity determined the success or failure of screening tests.
For small polyps, only one-tenth of those probabilities was used (38).
This study significantly extended earlier work in terms of the assumptions regarding polyp dwell time and post-polypectomy surveillance.
