The physician must have a high index of suspicion to detect SCC early in patients with malignancy. Back pain is the first symptom in almost all patients, and the diagnosis should be considered for all older patients with back pain. Asking about back pain should be a routine part of the review of systems, especially for patients with known malignancies. Clinically, it is impossible to tell whether or not a patient who has back pain and cancer has epidural SCC. Patients may be stratified as to the likelihood of SCC using the history and physical examination, but the diagnosis relies on radiographic visualization of the spinal cord. It may be acceptable to closely follow patients with normal neurologic examinations and normal plain films, but even this is controversial and includes only a minority of patients. Myelography remains the test of choice. MRI will play an increasingly important role in the future, but has not yet been systematically evaluated. The best therapeutic approach is not clear, but standard treatment is only about 50% effective in all cases. At present, radiation therapy is the treatment of choice for many patients, in particular those who are ambulatory at diagnosis. Anterior resection with vertebral body reconstruction is an exciting approach and may substantially improve the prognosis for patients who are paraparetic or paraplegic. It is important to attempt to choose for each patient the diagnostic and therapeutic options offering the best chance for comfort and preservation of function. The decision of how or even whether to treat is multifactorial and is more complicated than the determination of simply whether or not compression is present.(ABSTRACT TRUNCATED AT 250 WORDS)
医生必须保持高度的怀疑指数,以便在恶性肿瘤患者中早期发现脊髓压迫症。几乎所有患者的首发症状都是背痛,所有有背痛的老年患者都应考虑这一诊断。询问背痛应作为系统回顾的常规部分,尤其是对已知患有恶性肿瘤的患者。临床上,无法判断背痛且患有癌症的患者是否患有硬膜外脊髓压迫症。可根据病史和体格检查对患者发生脊髓压迫症的可能性进行分层,但诊断依赖于脊髓的影像学检查。对于神经系统检查正常且平片正常的患者进行密切随访可能是可以接受的,但即便如此也存在争议,而且仅适用于少数患者。脊髓造影仍是首选检查。MRI在未来将发挥越来越重要的作用,但尚未得到系统评估。最佳治疗方法尚不清楚,但在所有病例中标准治疗的有效率仅约为50%。目前,放射治疗是许多患者的首选治疗方法,尤其是那些诊断时仍能行走的患者。前路切除并椎体重建是一种令人兴奋的方法,可能会显著改善截瘫或四肢瘫患者的预后。为每位患者选择最有可能带来舒适感并保留功能的诊断和治疗方案非常重要。如何治疗甚至是否治疗的决定是多因素的,比单纯确定是否存在压迫更为复杂。(摘要截选至250字)
