Spinal epidural metastasis from cervical cancer: Report of two cases and literature review.

Spinal epidural metastasis(SEM) from cervical cancer is extremely rare, with only 6 cases reported in the literature, including our reported 2 cases. SEM mostly occurs in poorly differentiated carcinoma. Hematogenous spread is the primary mechanism of SEM from cervical cancer. The patients with SEM usually present with a range of clinical manifestations of nervous system because of spinal cord compression. SEM from cervical cancer indicates a late event with a poor prognosis. Local treatments mainly include surgery decompression and radiotherapy. Combining local and systemic therapy might be a better choice to prolong survival.
