Background: The incidence of testicular tumors in Poland accounts for 2.4 new cases per 100.000 men a year. When investigating the incidence with regard to age, we may notice three age ranges with the highest incidence rate: babyhood, 25-40 years of age, and age of about 60 years. A routine examination in patients with testicular cancer after the first course of chemotherapy is computed tomography of the retroperitoneal space which aims to exclude the presence of residual masses and to assess the effectiveness of the treatment.
Aim of the study: The assessment of the effectiveness of computed tomography in the intraoperative investigation of patients with nonseminoma testicular tumors after chemotherapy.
Material/method: This detailed retrospective analysis included 182 men with nonseminoma testicular tumor treated at the Center of Oncology in Cracow, between the yeas 1990-1999. Men with tumors in stage from IA to IIC made up 79.68% of the patients. Twenty patients after chemotherapy, with residual masses in the retroperitoneal cavity revealed in computed tomography, underwent retroperitoneal lymphadenectomy. The investigation was carried out with GE CT spiral scanner before and after intravenous contrast administration.
Conclusions: Computed tomography is a method of a satisfactory sensitivity in the assessment of residual masses in the retroperitoneal cavity in postchemotherapy patients, as concerns the location of the tumor, its size, number of foci, and the fact whether it can be operated on or not. Together with tumor markers, it allows for a precise qualification to retroperitoneal lymphadenectomy of residual masses in postchemotherapy patients.
