Reduced Erythropoietin Levels as a Cause of Anaemia in Patients with Lung Cancer. Cox, R., Musial, T., Gyde, O.H.B. The Department of Haematology, East Birmingham Hospital, Birmingham B9 5ST, U.K. Eur. J. Cancer Clin. Oncol. 22: 511-514, 1986. Measurement of erythropoietin (Ep) levels in patients with the anaemia of chronic disorders due to malignant disease have given variable results. This variation may be due to the wide range of malignancies studied and the assay method (whole animal) used. In this study Ep levels were measured, using the foetal mouse liver assay, in 39 patients with lung cancer and 19 controls. Twelve patients had reduced haemoglobin levels (Hb less than 11.5 g/dl for males and ii g/dl for females) and the features of the anaemia of chronic disorders. Their mean Ep level was 0.21 iu/ml. This was significantly lower than for the normal controls, whose mean value was 0.31 iu/ml (P < 0.02). This data supports the concept that lack of an appropriate Ep response to anaemia is one factor in the genesis of anaemia in malig- nancy. Atypical Carcinoid of the Lung: Radiographic Features.

Atypical carcinoid of the lung is a neuroendocrine neoplasm with cellular and clinical features intermediate between those of typical carcinoid and small cell undif- ferentiated carcinoma of the lung. These neoplasms exhibit a wide range of histologic appearance and are misdiagnosed in up to 50% of cases. The clinical records and radiographs of 32 patients with this diag- nosis from the University of Virginia Medi- cal Center and Wake Forest University Medi- cal Center were reviewed. Sixteen of these cases had been misdiagnosed pathologically. While the most frequent radiographic finding was a round or ovoid lobulated peripheral mass, other appearances included thin-walled cavities, poorly defined nonsegmental in- 45 filtrates, and mediastinal masses. Fifty percent of the patients in this study have died from their tumor, with a mean survival of 15.5 months. This contrasts with both typical carcinoid and small cell undifferen- tiated carcinoma, in which patients develop fatal metastatic disease in 5% and nearly 100%, respectively. Proper categorization of typical carcinoid, atypical carcinoid, and small cell undifferentiated carcinoma is necessary to determine appropriate therapy, prognosis, and reporting of end results.
