%X Treatment of castration-resistant prostate cancer is and has been a challenge. In 1957, the chemist Imre Könyves came to Sweden as a refugee from Hungary and started to work at AB Leo, a pharmaceutical company in Helsingborg. In 1961, he started to synthesize compounds where the oestrogens were linked to a mustard group by a carbamate. This resulted in estramustine phosphate, which was initially tested against mammary cancer with disappointing results. He then started a cooperation with urology professor Gösta Jönsson, Head of the Department of Urology at the Lund University Hospital, to test estramustine phosphate against prostate cancer. Jönsson started clinical estramustine phosphate tests in 1966. His studies were one-armed and consecutive, with a "favourable response" in 83% of previously untreated patients. These favourable results could not be reproduced in later randomized controlled studies suggesting that estramustine phosphate as primary treatment was not better than conventional estrogenic treatment. Conclusions: Even if the results of Gösta Jönsson's studies could not be confirmed, the subsequent randomized studies of estramustine phosphate may hide the desired action of estramustine phosphate in a subgroup of patients. It has still not been elucidated whether estramustine phosphate has effects in this subgroup of patients with ostrogen-resistant prostate cancer.
