Brain metastasis as the site of relapse in germ cell tumor of testis.
BACKGROUND
Brain metastases occur in approximately 8-15% of patients with testicular germ cell tumors and invariably are associated with relapse at other sites, most commonly the lungs, or as a terminal event.


METHODS
The authors, from the Institute Rotary Cancer Hospital, a regional cancer center in northern India, did a retrospective analysis to determine how many previously treated patients had isolated cerebral metastasis develop.


RESULTS
Three of 123 patients with testicular germ cell tumor seen during a 6-year period starting in January 1986 had isolated cerebral metastasis develop during remission after initial treatment. Two patients who had pure seminoma were treated with radiation therapy and are alive and symptom free at 15 and 18 months. The third patient had a combined tumor, the major component of which was embryonal cell carcinoma, that required debulking surgery and radiation therapy, and the patient died with recurrent cerebral metastases.


CONCLUSIONS
Review of the literature reveals that although cerebral metastasis is well recognized in testicular cancer, particularly nonseminomatous germ cell tumor (NSGCT), it is invariably preceded by systemic metastasis. Cerebral metastasis is extremely rare as the sole and presenting feature of relapse. This complication must be recognized and treatment defined because it may become more frequent as patients survive for longer periods with modern disease management.
