Paraneoplastic Sensory Neuronopathy And Spontaneous Regression Of Small Cell Lung Cancer

Abstract

BACKGROUND: Spontaneous tumour regression in small cell lung cancer has previously been suggested in patients with paraneoplastic neurologic syndromes. Rare documentation of this event has occurred in the literature. CASE REPORT: The authors report a patient with anti-Hu associated paraneoplastic sensory neuronopathy who had a spontaneous regression of her small cell lung cancer. CONCLUSIONS: This case supports the hypothesis that anti-Hu neurologic syndromes are the consequence of a misdirected immune response to small cell tumours.
