Aims. This study aimed to evaluate the incidence and prognosis of patients with
Patients with differentiated thyroid carcinomas (DTCs) have a favourable long-term survival. Spinal metastases (SMs) cause a decline in performance status (PS), directly affecting mortality and indirectly preventing the use of systemic therapies. Metastasectomy is indicated, if feasible, as it yields the best local tumour control. Our study aimed to examine the long-term clinical outcomes of metastasectomy for SMs of thyroid carcinomas. We collected data on 22 patients with DTC (16 follicular and six papillary carcinomas) and one patient with medullary carcinoma who underwent complete surgical resection of SMs at our institution between July 1992 and July 2017, with a minimum postoperative follow-up of five years. The cancer-specific survival (CSS) from the first spinal metastasectomy to death or the last follow-up was determined using Kaplan-Meier analysis. Potential factors associated with survival were evaluated using the log-rank test. We analyzed the clinical parameters and outcome data, including pre- and postoperative disability (Eastern Cooperative Oncology Group PS 3), lung and non-spinal bone metastases, and history of radioiodine and kinase inhibitor therapies.Aims
Methods
With recent progress in cancer treatment, the number of advanced-age patients with spinal metastases has been increasing. It is important to clarify the influence of advanced age on outcomes following surgery for spinal metastases, especially with a focus on subjective health state values. We prospectively analyzed 101 patients with spinal metastases who underwent palliative surgery from 2013 to 2016. These patients were divided into two groups based on age (< 70 years and ≥ 70 years). The Eastern Cooperative Oncology Group (ECOG) performance status (PS), Barthel index (BI), and EuroQol-5 dimension (EQ-5D) score were assessed at study enrolment and at one, three, and six months after surgery. The survival times and complications were also collected.Aims
Methods
Patients with solitary spinal metastases from Renal Cell Carcinoma (RCC) have better prognosis and survival rates compared to other spinal metastatic disease. Adjuvant therapy has been proven ineffective. Selected patients can be treated with Total En bloc Spondylectomy (TES) for solitary intra-osseous metastasis in the thoracolumbar spine secondary to renal cell carcinoma. Five patients with solitary vertebral metastasis secondary to RCC underwent TES for radical resection of the spinal pathology after pre-operative embolisation. The procedure involves en bloc laminectomy and corpectomy with posterior instrumented fusion and anterior instrumentation with cage reconstruction following the spondylectomy. All patients were fully staged pre-operatively and assessed according to the Tokuhashi scoring system. Recurrence of
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
The aim of this study was to investigate the incidence and characteristics of instrumentation failure (IF) after total en bloc spondylectomy (TES), and to analyze risk factors for IF. The medical records from 136 patients (65 male, 71 female) with a mean age of 52.7 years (14 to 80) who underwent TES were retrospectively reviewed. The mean follow-up period was 101 months (36 to 232). Analyzed factors included incidence of IF, age, sex, BMI, history of chemotherapy or radiotherapy, tumour histology (primary or metastasis; benign or malignant), surgical approach (posterior or combined), tumour location (thoracic or lumbar; junctional or non-junctional), number of resected vertebrae (single or multilevel), anterior resection line (disc-to-disc or intravertebra), type of bone graft (autograft or frozen autograft), cage subsidence (CS), and local alignment (LA). A survival analysis of the instrumentation was performed, and relationships between IF and other factors were investigated using the Cox regression model.Aims
Methods
The aims of this study were to determine the diagnostic yield of image-guided biopsy in providing a final diagnosis in patients with suspected infectious spondylodiscitis, to report the diagnostic accuracy of various microbiological tests and histological examinations in these patients, and to report the epidemiology of infectious spondylodiscitis from a country where tuberculosis (TB) is endemic, including the incidence of drug-resistant TB. A total of 284 patients with clinically and radiologically suspected infectious spondylodiscitis were prospectively recruited into the study. Image-guided biopsy of the vertebral lesion was performed and specimens were sent for various microbiological tests and histological examinations. The final diagnosis was determined using a composite reference standard based on clinical, radiological, serological, microbiological, and histological findings. The overall diagnostic yield of the biopsy, and that for each test, was calculated in light of the final diagnosis.Aims
Methods
To evaluate the perioperative complications associated with total en bloc spondylectomy (TES) in patients with spinal tumours, based on the extent and level of tumour resection. In total, 307 patients who underwent TES in a single centre were reviewed retrospectively. There were 164 male and 143 female patients with a mean age at the time of surgery of 52.9 years (SD 13.3). A total of 225 patients were operated on for spinal metastases, 34 for a malignant primary tumour, 41 for an aggressive benign tumour, and seven with a primary of unknown origin. The main lesion was located in the thoracic spine in 213, and in the lumbar spine in 94 patients. There were 97 patients who underwent TES for more than two consecutive vertebrae.Aims
