Nerve Conduction And Evoked Potentials

In The Patients With Lung Cancer It is well known that lung cancer is one of the main causes of the paraneoplastic neuropathy syn-dromes. Although the lung cancer has remote effect on peripheral nerves, whether it affects central neu-ronal pathways is not clear. In this study visual, auditory and somatosen-soriel evoked evoked potentials (VEP,BAEP,SEP re-spectively) are recorded in the 28 patients with lung cancer in whom no cerebral metastase were found-ed. Nerve conduction study showed sensory neurop-athy in 7 patients (25%). VEP latencies were path-ologically delayed in 4 patients (19.'4%). Frequency in the abnormal delay of SEP (N19 and 131) is also 19.4%. BAEP could not he elicited in 5 patients (17.24%). We concluded that central neuronal path-ways are also he influenced by remote effect of the lung cancer. However its central effect is not so _fre-quent as peripheral one.
