TL;DRAbstract

It has been suggested that cyproterone acetate (CPA) has a mutagenic potency. It has been postulated that a threshold dosage of CPA has mutagenic effects, but in the same way data have been published documenting that a continuous low dosage of cyproterone acetate leads to a reduction of mutagenic episodes. Despite published data about higher levels of DNA adduct creations due to CPA an international multicentre study analysing 2,506 patients with 7,971 patient-years that used CPA could not find any liver cell cancers, even if due to epidemiological data 6 liver cell cancers should have occurred upon this study group. The present study deals with the evaluation of 57 women which received CPA in combination with EE2 11-13 years before. The daily dosage was 2 mg CPA in combination with 35 mg or 50 mg EE2. In Germany these drugs were registered under the name of Diane 35 or Diane 50. Long-term follow-up evaluation concerning side effects, especially the appearance of liver cell carcinomas,
