Spots Global Cancer Trial Database for Surgical Spinal Decompression of Metastatic Spinal Cord Compression, Minimal Access Versus Open Surgery

Study Description

Brief Summary: The investigators wish to evaluate the effect of minimal access spinal surgery compared to traditional open surgery spinal surgery in patients with metastatic spinal cord compression. Minimal access surgery has been shown to bee less damaging for the tissue compared to traditional open surgery and also cause fewer wound complications, the investigators expect the above could have impact in a vulnerable patient group like patients with metastatic spinal cord compression.

Detailed Description: Surgical Spinal Decompression of Metastatic Spinal Cord Compression, Minimal Access Versus Open Surgery. A Randomized Clinical Trial Purpose To investigate the effect of minimal access spine surgery (MASS) compared with conventional open surgery in the treatment of patients with metastatic spinalcord compression (MSCC). Hypotheses The group of patient's receiving MASS will have better improvement in quality after surgery compared to the group that will receive traditional open surgery. The MASS patient group will have reduction in per-operative bleeding and less wound complications needing surgical revision compered to the group of patients receiving open or traditional surgery. Primary outcome Perioperative bleeding. Secondary outcomes Quality of life and incidence of revision surgery. Material and method A randomised controlled trial with a 1-year follow up will be conducted. Sample size From previous studies and based patient files it is calculated that the mean blood loss during open surgery is 1500 ml (standard deviation 750 ml). A clinical relevant reduction in blood loss will be 400 ml corresponding to one unit of packed red blood cells. With a significance level of 5% and a power of 80% a total of 62 patients have to be included in the study. Most studies using QLQ-C30 as a measurement for health related quality of life (HRQL) in randomized comparison of treatment modalities in cancer patients have included between 100 and 200 patients. This includes studies where both QLQ-C30 and EQ-5D have been used. EQ-5D is widely used as a generic measurement of HRQL. 62 patients will be randomly allocated to receive either minimal invasive or open surgery. Inclusion criteria are patients with spinal metastases at level Th5-L3 who are candidates for surgery. Exclusion criteria are: Tokuhashi score ≤ 4, preoperative presumptions that something else than pedicle screws would be needed, potentially the need for sacral or iliosacral instrumentation, and patients who need more radical treatment. The QLQ-C30 (Quality of Life Cancer) will be assessed since this instrument is especially developed for use in cancer patients and will be used as a clinical measure. Outcome measure on bleeding will be recorded during the operation. Outcome measures on quality of life will be estimated with QLQ-C30, EQ-5D and VAS-pain score. This will be recorded before operation, by time of discharge, 6 weeks and 3, 6 and 12 months after the operation. Records on wound complications leading to an intervention of revision-surgery, antibiotics or other procedures are registered at the same follow up times.
