人们对各种恶性肿瘤向神经系统的转移早已熟知,但对另一种情况,即既不是由于原发肿瘤的直接侵犯,又非癌肿转移所引起的一大组神经系统并发症,亦称副肿瘤性神经系统综合病征(Paraneoplastic neurologic Syndromes)或称癌肿对神经系统的远隔影响,则相对地尚嫌重视不够,这不仅从临床医师很少得出这类疾病的诊断,而且 The transfer of various malignant tumors to the nervous system has long been known, but in another case, it is neither a direct violation of the primary tumor nor a large group of neurological complications caused by cancer metastasis. The paraneoplastic neurologic syndromes or cancers affect the distance from the nervous system. Relatively insufficient attention has been paid to this issue. This is not only rarely diagnosed by clinicians but also by the clinician.
