Rosamund – Interview 18
Rosamund is taking part in a large trial testing the effectiveness of screening for ovarian cancer. She is in the control group, so she has no screening tests but completes regular questionnaires.
Rosamund received a letter inviting her to take part in a large ten-year trial of the effectiveness of screening for ovarian cancer. The trial compares a control group (no screening) with two different types of screening. One screening group has a regular blood test plus vaginal ultrasound if the blood test shows any unusual results, or vaginal ultrasound on its own.
Rosamund has worked in research for many years and has personal experience of designing and running trials. In principle she is strongly in favour of randomised controlled trial research, and felt she had a moral responsibility to take part. However, she felt the leaflet which came with the letter did not contain enough information to enable her to decide whether to take part and so she asked to be sent a copy of the full study protocol; or detailed description. This took six weeks to arrive. In particular she wanted to know more about the possible discomfort of vaginal ultrasound and about the risk of being diagnosed incorrectly with ovarian cancer (a false positive; result), or being reassured that you do not have cancer when in fact you do (a false negative;). She was also unhappy that there was no choice of appointment times outside working hours.
Once she had this extra information, Rosamund agreed to take part in the trial, because ovarian cancer is known as the silent killer; and it is important to find ways of detecting it earlier when it might be more treatable. She has known someone who died from the condition, and she herself has also had cancer in the past. However, at a personal level she was worried about being randomised to one of the groups having vaginal ultrasound and was relieved when she was told she was in the control group. She might have considered withdrawing if she had been allocated to either of the screening groups. Now that she has agreed to take part, she believes it is important to stay in the trial. As a researcher she knows how frustrating it can be if people drop out part-way through.
Taking part in the trial has involved filling in questionnaires about her psychological well-being, as the trial includes a study of how screening may affect quality of life and levels of anxiety. Rosamund was surprised that the questionnaire seemed to include a lot of questions on women’s sexual activity, and did not feel it was very well designed to reflect the things that are important to women themselves. She believes it is important that researchers involve lay people in designing their studies, and that the principles of trial design and randomisation are better explained to the public.
