Upper abdominal lymphadenopathy as first presentation of relapse, identified by ultrasonography, in patients treated for small cell (oat cell) bronchogenic carcinoma.

Ten patients treated for 'limited' stage small cell lung cancer presented during follow-up with epigastric or back pain together with nausea and/or vomiting. Upper abdominal lymphadenopathy was shown to be the first symptomatic site of relapse. A single fraction of radiotherapy provided a convenient, effective form of palliation. Ultrasound scanning proved an accurate, readily available technique for the diagnosis of this form of intra-abdominal disease.
