Your doctor has recommended a medication called Stilboestrol as treatment for your prostate cancer. This page provides extra information about your medicine, summarises possible side effects and methods to alleviate them. What is Stilboestrol? An oral tablet taken at a dose of 3-5mg once a day, belongs to group of medicines called man made oestrogens (the female hormone). They are used to treat male patients with prostate cancer. Many people like to take it at the same time each day the actual time does not matter. Some prefer to take it with food some after meals - try to find a convenient time and stick to it as its easier to remember to take the tablets in the long term. If you forget to take your tablet dont panic levels of the drug in your blood will not change very much not to miss more than one or two tablets in a row. Remember to get a new prescription a couple of weeks before you run out of the tablets and make sure you have plenty for holidays etc. How do they work? Some tumours such as prostate cancer are stimulated by the bodies own male hormone (Testosterone). Stopping the bodies testosterone reaching the tumour can cause the cancer cells to stop growing and in some cases shrivel up and die completely (self destruct - apoptosis). Stilboestrol works by fooling the signal pathway between the brain and the testes by increasing the blood levels of a chemical which looks like the female hormone oestrogen. In turn the brain thinks the testies are producing too many sex hormones including testosterone and as a consequence switches off the driving signal by itself - this results in a marked reduction in the blood level of testosterone. How will I & the doctor know they are working? In most cases there is something the doctor can measure. This may be how you feel, a symptom related to your cancer, something which can be felt on examination (e.g. a lump or size of prostate), something seen on a scan or xray. or a blood test called PSA, (the level of which will get lower if you are responding).
