Background:
Testicular cancer is one of those cancers for which the prognosis has improved remarkably since the introduction of effective chemotherapy.
Methods:
Study subjects were 709 testicular cancer patients who were registered to the population-based Osaka Cancer Registry (OCR) as diagnosed between 1975 and 1992. The testicular cancer patients diagnosed/treated in the Osaka Medical Center for Cancer and Cardiovascular Diseases (OMCC) were also analyzed for comparison.
Results:
The 5-year relative survival was 75.2% for the total of 709 patients and 77.9% for those diagnosed during 1990-92. These figures were much lower than those for patients in the USA and in Europe. In contrast, the 5-year survival of the 113 patients diagnosed in the OMCC during 1975-93 was 91.5% and similar to those in the USA and in Europe.
Conclusions:
The present study suggests that there are problems in the speed and extent of diffusion of effective chemotherapy for testicular cancer in Osaka.
