Objective: The purpose of this study is to provide key information on the clinical characteristics, surgical treatment, and potential prognostic factors in patients with metastatic spinal gynecologic cancer (MSGC), with a view to their application in clinical practice.
Methods: From January 2010 to January 2020, we performed a retrospective analysis of 14 patients with MSGC who underwent surgical treatment in a single center. Surgical treatment was performed on 14 patients, and a total of 14 operations were performed. The survival time of patients after spinal surgery was analyzed by Kaplan–Meier and Cox regression analysis.
Results: The average age of patients was 51.9 years (range 25‒70). The average time from initial surgery to the discovery of spinal metastasis was 60.3 months (2‒180), and the average follow-up time was 19.2 months (2‒55). Spinal tumor progression was found in 9 patients, and 12 patients (85.7%) died during follow-up. In univariate analysis, extraosseous visceral metastasis (p = 0.024), revised Tokuhashi stage (p = 0.025), Tomita stage (p = 0.005), and number of spinal lesions (p = 0.038) were associated with overall survival (OS). Extraosseous visceral metastasis (p = 0.026), revised Tokuhashi stage (p = 0.014), Tomita stage (p = 0.001), and gynecological cancer type (p = 0.039) were associated with progression-free survival.
Conclusion: Surgical treatment is an effective treatment for MSGC and relieves pain, restores function and rebuilds stability. Based on our single-center experience, extraosseous visceral metastasis, revised Tokuhashi stage, Tomita stage, and gynecological cancer type may be potential prognostic factors for OS.
