Assessment of prognostic factors in patients with metastatic epidural spinal cord compression (MESCC) from solid tumor after surgery plus radiotherapy: A single institution experience

Research output: Contribution to journalArticle

Abstract

Purpose: To identify potential prognostic factors predicting functional outcome and survival after surgery followed by radiotherapy for metastatic spinal cord compression due to solid tumors. Methods: 531 consecutive patients with metastatic epi-dural spinal cord compression (MESCC) were treated at our institution. Surgery followed by radiation therapy was performed in 151 patients (30%) with various histological diagnoses. Three different surgical procedures were performed: minimal resection with or without instrumented fixation, curettage, and total tumorectomy. Within 1 month after surgery, RT was performed, delivering a total dose of 30-36 Gy (3 Gy per fraction). Ten potential prognostic factors were investigated for relationship with functional outcome and survival. Results: Clinical remission of pain was obtained in 91% of patients and 94 (62.5%) had recovery of neurological deficit. Recurrence in the same site of treatment occurred in nine (6%) patients. Median survival was 14 months (range 0-52 months); OS at 1, 2, and 3 years was 43.6, 37, and 21.5%, respectively. Survival was significantly associated with the histology of primary tumor (P <0.001) and visceral metastases (P <0.001) in the whole group; for histology, the prognostic factors statistically significant were other bone metastases in breast cancer, control of primary tumor, and the absence of visceral metastases in NSCLC and kind of surgery in the other. Conclusions: The key element for successful treatment of MESCC is multidisciplinary care of the patient, which includes all of those prognostic factors that have been, until now, analyzed and compared. In our set of patients treated for vertebral metastases, PS, time to development of symptoms, and the presence of visceral metastases affected functional outcome and survival.
