A note on the catch-up time method for estimating lead or sojourn time in prostate cancer screening
Models of cancer screening assume that cancers are detectable by screening before being diagnosed clinically through symptoms. The duration of this preclinical phase is called sojourn time, and it determines how much diagnosis might be advanced in time by the screening test (lead time). In the catch-up time method, mean sojourn time or lead time are estimated as the time needed for cumulative i...
متن کاملEstimating mean sojourn time and screening sensitivity using questionnaire data on time since previous screening.
OBJECTIVES Mean sojourn time (MST) and screening test sensitivity (STS), is usually estimated by Markov models using incidence data from the first screening round and the interval between screening examinations. However, several screening programmes do not have full registration of cancers submerging after screening, and increased use of opportunistic screening over time can raise questions reg...
متن کاملLung cancer screening: ready for prime time?
N ews from the National Lung Screening Trial (NLST) in November made headlines worldwide: A screening program had succeeded in cutting deaths from the world’s most lethal cancer by 20%. In this randomized, controlled trial, 54,000 current or former heavy smokers aged 55 – 74 years received either chest X-rays or low-dose helical computed tomography (CT) scans in an attempt to detect lung cancer...
متن کاملLung cancer screening: has its time come?
Reflecting lung cancer screening’s potential for complexity, the article in this issue by Drs. Brawley and Flenaugh points out that there are so many different solitary nodules found on the low-dose helical computerized tomography (LDCT) used for lung cancer screening that algorithms are being developed to more effectively and accurately distinguish benign lesions from malignant ones. The major...
متن کاملEstimates of Breast Cancer Growth Rate and Sojourn Time from Screening Database Information
A new method has been developed that can be used to estimate tumor growth rate from information on the numbers and sizes of breast cancers found at screening. With use of this method and information available for the tumors seen over the last decade at the Breast Imaging Division at the Massachusetts General Hospital (MGH), it appears that the median doubling time for invasive breast cancer is ...
