Author Interviews, Prostate Cancer / 05.04.2023

MedicalResearch.com Interview with: Freddie C. Hamdy FRCS, FMedSci Nuffield Professor of Surgery, University of Oxford Jenny L. Donovan PhD, FMedSci Professor of Social Medicine, University of Bristol     MedicalResearch.com: What is the background for this study? Response:  Prostate cancer is a common malignancy in men. Prostate cancer diagnosis is made largely through opportunistic screening with a PSA (Prostate Specific Antigen) blood test, followed by prostate biopsies. The ProtecT study, funded by the National Institute for Health and Care Research in the UK, is the largest randomised trial of treatment in screen-detected localised prostate cancer. The study began by testing 82,429 men between the ages of 50 and 69 years, across nine UK centres with a PSA blood test, followed by biopsies of the prostate if the PSA level was elevated. 2,664 men with clinically localised prostate cancer were found. From these, 1,643 (62%) agreed to be randomised to Surgery (radical prostatectomy to remove the prostate gland), Radiotherapy (external beam with a period of hormone treatment beforehand), or Active Monitoring (where men received regular checks and further investigations, with change to radical treatment as necessary). The men were carefully followed up for an average of 15 years. In parallel, the side-effects of treatments and quality of life of these men was investigated using patient-reported outcomes included in an annual study questionnaire completed for at least 12 years.

MedicalResearch.com Interview with: Florence Z. Martin MRC Integrative Epidemiology Unit Population Health Sciences Bristol Medical School University of Bristol, Bristol, UK MedicalResearch.com: What is the background for this study? Response: Globally, rates of caesarean section are on the rise. Many things are contributing to this, including increasing maternal age, more women who have had prior caesareans, and changes in maternal preference. One reason that women have been cited to choose a caesarean in an uncomplicated pregnancy is the maintenance of sexual wellbeing postpartum (in other words, after their baby is born). The protection of sexual wellbeing following caesarean section is thought to be via the maintenance of vaginal tone and reduced risk of vaginal tearing. However, few studies have shown this to be true. Some studies investigating sexual outcomes in the year after birth found no difference between women who gave birth vaginally and those who delivered via caesarean section. Longer term evidence is sparse, with only one study looking up to 16 years postpartum and finding that women who give birth to all their children via caesarean section are at higher risk of experiencing sex-related pain. To contribute to previous studies and provide the first piece of evidence looking at sexual wellbeing as a whole several years after delivery, we used data from the Children of the 90s study (also known as the Avon Longitudinal Study of Parents and Children or ALSPAC). We aimed to compare sexual enjoyment, sexual frequency, and sex-related pain between women who delivered via caesarean section and those who delivered vaginally up to 18 years postpartum. (more…)
