Plain English Summary
Background and study aims
Bladder cancer is where a tumour develops in the bladder lining. Patients who have high risk early bladder cancer, invasive bladder cancer or locally advanced bladder cancer may have to have their bladder removed (radical cystectomy). In women, sometimes the ovaries may also need to be removed (oophorectomy). There are at present no studies on whether oophorectomy should be performed with radical cystectomy as treatment for muscle-invasive bladder cancer in women. Information is also lacking regarding the effects on hormone levels and sexual function. The aim of this study is to assess the hormone levels and sexual function of women undergoing radical cystectomy with or without oophorectomy for bladder cancer.
Who can participate?
Women aged 18-85 undergoing radical cystectomy for bladder cancer
What does the study involve?
Participants are randomly allocated to undergo radical cystectomy with either no oophorectomy, removal of one ovary or removal of both ovaries. Sexual function and blood hormone levels are assessed at the start of the study and 12 and 52 weeks after the operation.
What are the possible benefits and risks of participating?
Participants allocated to no oophorectomy may benefit from better hormonal, sexual and general function after surgery. There are no risks in participating in this study.
Where is the study run from?
Skåne University Hospital (Sweden)
When is the study starting and how long is it expected to run for?

Condition
Bladder cancer treated with radical cystectomy
Intervention
Patients undergoing radical cystectomy will be randomized using closed envelopes to undergo either:
1. No oophorectomy
2. Excision of one ovary
3. Excision of both ovaries
Oophorectomy will be performed by standard surgical methods, including ligation of parametrium with Ligasure when preserving the one or two ovaries. Follow-up will be 12 months postoperatively according to the protocol, however clinical follow-up will be according to clinical routines.
