FDG-PET evaluation of retroperitoneal metastases of testicular cancer before and after chemotherapy.

We describe a patient whose primary tumor was a testicular teratocarcinoma predominantly composed of embryonal carcinoma. Before chemotherapy, the retroperitoneal metastases demonstrated heterogeneous, increased glucose metabolism as measured by 2-[18F]fluoro-2-deoxy-D-glucose and PET (FDG-PET). After chemotherapy, FDG uptake was reduced to normal values despite increased tumor volume. Histology revealed a pure mature teratoma. This observation suggests that further studies are needed to determine whether tumor differentiation of testicular teratocarcinoma metastases can be assessed by measuring glucose metabolism.

Aging and arterial functions.

Normally it is difficult and quite frequently impossible to separate physiological aging from its pathophysiological variant. Biochemical, physical and morphological alterations in the arterial wall show a dependence on age. This was the reason for investigating the extent to which the peripheral arterial hemodynamics are changed by age. The parameters, measured by electronic oscillogram, ultrasonic-Doppler-technique and radioangiography, show age dependent alterations. However it must be considered, that peripheral arterial hemodynamics are also influenced by age dependent alterations in cardiac functions.
