BACKGROUND: Germ cell tumors (GCTs) are chemosensitive, and epidural spinal cord compression (ESCC) from GCT may be amenable to treatment with chemotherapy (CT) only. This retrospective study compares the clinical outcome of GCT patients with ESCC treated with CT or radiotherapy (RT) + CT. METHODS: All patients with a histologic diagnosis of GCT from 1984 to 2009 were included in this study. Patients with ESCC were identified. Age, clinical features, histology, treatment, and outcome were analyzed. RESULTS: The authors identified 1734 patients with GCT, of whom 29 (1.7%) had ESCC. The median age of these 29 patients was 32 years. The ESCC was treated with CT only in 16, RT + CT in 11, and 2 patients received palliative care only. The ESCC was more extensive in the RT + CT than the CT group. Patients who received RT + CT had a higher proportion of failed prior CT regimens, a higher percentage of nonseminomatous GCT, T-spine involvement, multilevel epidural disease, and bony vertebral metastases. Median overall survival after diagnosis of ESCC was not reached for those treated with CT alone versus 15 months for those receiving RT + CT (P = .02). There was also a significant difference in survival in patients receiving first-line therapy (n = 15), where median overall survival was not reached in the CT group (n = 11), compared with 22 months in the RT group (n = 4) (P = .04). CONCLUSIONS: GCTs rarely involve the epidural compartment. Patients with ESCC who are likely to have chemosensitive disease can receive CT alone as definitive treatment.
