Background: Testicular cancer is one of the few solid cancers that can be cured even when it is metastasized with overall survival rate of more than 90%. The aim of this study was to establish the age adjusted incidence of testicular cancer and to critically assess the management of testicular tumor.
Methods: This is a quantitative retrospective study utilizing a review of clinical notes for patients who underwent testicular orchidectomy. The number of cancer cases, types of pathology and cancer staging were examined.
Results: There is no substantial difference between the crude and the age-standardized incidence, moreover no difference from the reported crude incidence by the Scottish intercollegiate guidelines. We found 55.1% of seminoma, 14.28% of non-seminoma and 30.61% of combined (seminoma and non-seminoma), and stage I disease in 61.22% of cases, stage II in 36.73% of cases, and stage IV in 2.04% of cases. Most of the cancers were in the age group 20 - 50 with the majority (48.97%) in the age group 31 - 40. About 42.85% of cases were identified with high tumor markers; higher percentage of seminoma at stage II (40.74%).
Conclusions: There is no substantial difference between the crude and the age-standardized incidence, moreover no difference from the reported crude incidence. Most of the cancers were in the age group 20 - 50 with the majority (48.97%) in the age group 31 - 40. Only 25% of seminomas had elevated tumor markers. Moreover, it is important to re-enforce strict adaptation to the IGCCCG prognostic factor-based classifications.
