Background: In UKCTOCS, there was a decrease in the diagnosis of advanced stage tubo-ovarian cancer but no reduction in deaths in the multimodal screening group compared with the no screening group. Therefore, we did exploratory analyses of patients with high-grade serous ovarian cancer to understand the reason for the discrepancy. Methods: UKCT...

Randomised controlled trials are challenging to deliver. There is a constant need to review and refine recruitment and implementation strategies if they are to be completed on time and within budget. We present the strategies adopted in the United Kingdom Collaborative Trial of Ovarian Cancer Screening, one of the largest individually randomised co...

Article
(Abstracted from Lancet 2021;397:2182–2193) Ovarian cancer is most commonly diagnosed at an advanced stage (3 or 4) and remains the deadliest gynecologic malignancy. When diagnosed at stage 1, a survival rate of greater than 90% has been demonstrated, compared with a 5-year survival rate of 27% and 13% for stage 3 and stage 4 disease, respectively.

Article
Full-text available
Background Ovarian cancer continues to have a poor prognosis with the majority of women diagnosed with advanced disease. Therefore, we undertook the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) to determine if population screening can reduce deaths due to the disease. We report on ovarian cancer mortality after long-term follow-up i...

Background During trials that span decades, new evidence including progress in statistical methodology, may require revision of original assumptions. An example is the continued use of a constant-effect approach to analyse the mortality reduction which is often delayed in cancer-screening trials. The latter led us to re-examine our approach for the...

Full-text available
Simple Summary The United Kingdom Collaborative Trial of Ovarian Cancer Screening was undertaken to assess whether screening postmenopausal women from the general population might result in detection of ovarian/tubal cancers at an earlier stage and thus save lives. One of the screening strategies tested was a yearly transvaginal ultrasound scan of...

Objectives: Estrogen is a well-established risk factor for various cancers. It causes endometrial proliferation which is routinely assessed as endometrial thickness (ET) by transvaginal ultrasound (TVS). Only one study, restricted to endometrial and breast cancer, has previously considered ET and risk of a non-endometrial cancer. This study seeks...

The short-term psychological effects on the mother of real-time ultrasound examination early in pregnancy have been evaluated. Primiparae were randomly assigned to one of two groups: a high feedback, where they saw the monitor screen; b low feedback, where the scan was accompanied by a global evaluation of progress. Women were assessed before and a...
