Abstract
A prospective study was performed to evaluate the efficacy and safety of percutaneous kyphoplasty in patients with osteolytic tumours of thoracic and lumbar spine. To our knowledge this is the only study so far that has followed a cohort of patients prospectively until death.
Prospective study of patients with lytic tumours of spine treated with kyphoplasty.
A total of 13 patients with osteolytic tumours of spine were treated with kyhpoplasty. There were 8 female and 5 male patients. The age range was 52-81 years with average age of 65 years. A total of 25 vertebrae, from T2 to L3, were treated. The types of tumours included; non-Hodgkin lymphoma (2), myeloma (2), gastric-carcinoma (1), cervix-carcinoma (1), breast-carcinoma (3), prostate-carcinoma (2), small cell lung-carcinoma (1), bladder-carcinoma (1).
Outcome was assessed prospectively by visual analogue scale (VAS) for pain, ECOG performance status, walking distance, standing and sitting time.
The preoperative average VAS was 7.5 (range: 2.6 – 10). This dropped to 3.0 five days postoperatively and remained below 5 for the duration of follow-up. Average walking distance, standing and sitting time and ECOG performance score showed improvement. The survival time ranged from 2 to 293 weeks. The average survival time was 82 weeks. All patients were able to return home following the procedure. No patient required reoperation or readmission for spinal metastasis.
Kyphoplasty is a suitable palliative treatment option for patients with advanced metastatic disease of the spine.
