Staging investigations and prognostic grouping

Staging investigations will include, in all patients, a CT scan of the thorax, abdomen, and pelvis. In patients with a high HCG (greater than 10 000 international units per litre) or bulky mediastinal disease, a brain scan is advisable. Post-operative tumour markers should be serially checked, if raised, to assess whether or not they are falling according to a satisfactory half life (4-6 days for AFP, 24 hours for HCG). Other investigations such as a bone scan may be necessary if specifically indicated.

Until recently the Royal Marsden Hospital (RMH) staging has been used for both teratomas and seminomas. The IGCCC prognostic grouping is now more applicable, particularly for teratomas.
