Surgery for metastatic spine tumors in the elderly. Advanced age is not a contraindication to surgery!

BACKGROUND: With recent advances in oncologic treatments, there has been an increase in patient survival rates and concurrently an increase in the number of incidence of symptomatic spinal metastases. Because elderly patients are a substantial part of the oncology population, their types of treatment as well as the possible impact their treatment will have on healthcare resources need to be further examined. PURPOSE: We studied whether age has a significant influence on quality of life and survival in surgical interventions for spinal metastases. STUDY DESIGN: We used data from a multicenter prospective study by the Global Spine Tumor Study Group (GSTSG). This GSTSG study involved 1,266 patients who were admitted for surgical treatments of symptomatic spinal metastases at 22 spinal centers from different countries and followed up for 2 years after surgery. PATIENT SAMPLE: There were 1,266 patients recruited between March 2001 and October 2014. OUTCOME MEASURES: Patient demographics were collected along with outcome measures, including European Quality of Life-5 Dimensions (EQ-5D), neurologic functions, complications, and survival rates. METHODS: We realized a multicenter prospective study of 1,266 patients admitted for surgical treatment of symptomatic spinal metastases. They were divided and studied into three different age groups: <70, 70-80, and >80 years. RESULTS: Despite a lack of statistical difference in American Society of Anesthesiologists (ASA) score, Frankel neurologic score, or Karnofsky functional score at presentation, patients >80 years were more likely to undergo emergency surgery and palliative procedures compared with younger patients. Postoperative complications were more common in the oldest age group (33.3% in the >80, 23.9% in the 70-80, and 17.9% for patients <70 years, p=.004). EQ-5D improved in all groups, but survival expectancy was significantly longer in patients <70 years old (p=.02). Furthermore, neurologic recovery after surgery was lower in patients >80 years old. CONCLUSIONS: Surgeons should not be biased against operating elderly patients. Although survival rates and neurologic improvements in the elderly patients are lower than for younger patients, operating the elderly is compounded by the fact that they undergo more emergency and palliative procedures, despite good ASA scores and functional status. Age in itself should not be a determinant of whether to operate or not, and operations should not be avoided in the elderly when indicated.

Unexpected symptoms after rhTSH administration due to occult thyroid carcinoma metastasis.

¹8F-fluorodeoxyglucose positron emission tomography (¹8FDG-PET) scintigraphy is a useful imaging technique in the evaluation of metastasised thyroid carcinoma. Administration of recombinant human thyrotropin (rhTSH, Thyrogen®) increases the diagnostic yield of this procedure. Here we present a 64-year-old male who was followed for Hürthle cell carcinoma of the thyroid with several intrapulmonary metastases. He developed sudden complaints of neck pain following rhTSH administration as part of the routine preparation for a diagnostic ¹8FDG-PET÷CT procedure. This investigation subsequently revealed a previously undetected metastatic lesion in the first cervical vertebra, with no signs of spinal cord compression. Treatment with a nonsteroidal anti-inflammatory drug reduced the symptoms sufficiently, and a few weeks later the neurosurgeon performed a complete resection of the metastasis. It is likely that the symptoms were caused by oedema and÷or increased blood flow to the lesion. Physicians should be aware that rhTSH administration to patients with disseminated thyroid carcinoma may lead to sudden onset of symptoms caused by previously occult metastases.

[Diagnosis and treatment of patients with spinal epidural metastases]. / Diagnostiek en behandeling van patiënten met spinale epidurale metastasen.

Three patients with a medical history of malignancy were referred for back pain: two women aged 53 and 43 years respectively, with breast cancer, and a woman of 85 years with rectal carcinoma. All patients suffered from spinal metastasis. Considerable delay occurred between the initial complaint of back pain and the diagnosis. This adversely influenced the outcome after treatment. A reliable differentiation, based on symptoms and signs, between widely occurring non-malignant back pain and back pain due to spinal metastasis is impossible. This confronts physicians with the dilemma of overexposing their patients to diagnostic tests on the one hand and the risk of missing an important diagnosis on the other. Early recognition of warning signs, i.e. previous medical history of malignancy, onset of back pain above 50 years of age, continuous pain not related to posture or movement and nocturnal pain, should alert physicians.

Neurenteric cyst--a case report of this rare disorder.

Neurenteric cysts are rare congenital lesions that are believed to be the result of the split notochord syndrome. We report the clinical case of a 5-year-old boy presenting with vague gastrointestinal symptoms and fatigue, who had undergone resection of a small intestine duplication cyst as a newborn. Computed tomography revealed a mediastinal neurenteric cyst with partial destruction of several thoracic vertebrae. Resection of the tumor proved effective. Recognition of this disorder is important: because of its benign nature, the prognosis after surgical resection can be good. If the diagnosis is made in an early stage, unnecessary progressive destruction of surrounding structures may be prevented.

Image guided surgery: new technology for surgery of soft tissue and bone sarcomas.

AIM: Providing the surgical oncologist with a new means of performing safe and radical sarcoma surgery with the help of image guidance technology. METHOD: Two patients with pelvic sarcomas were operated upon with the help of an intra-operative navigation system. The technology of image guided surgery is described in one patient with a retroperitoneal sarcoma invading the bony pelvis and another patient with a chondrosarcoma of the iliac crest. RESULTS: We show that this new procedure enables optimal radical surgical resection with minimal treatment related morbidity or loss of function. CONCLUSION: Image guided surgery is a new technical tool in sarcoma surgery.
