Reduced Erythropoietin Levels as a Cause of
Anaemia in Patients with Lung Cancer.

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.
Bronchial Carcinoma Presenting with Non-
Metastatic Bilateral Papillitis.

Bronchial carcinoma is associated with
a variety of non-metastatic neurological ef-
fects (Posner 1982). I report on a patient
in whom bilateral papillitis was the
presenting feature of squamous carcinoma of
lung. Investigations revealed no evidence of
cerebral secondary tumour and resolution of
the papillitis followed dexamethasone
therapy and resection of the carcinoma.

Small Cell Carcinoma of the Lung - to
Operate or Not? Surgical Experience and
Results.

From 1962 to 1979, out of 549 patients
with small cell bronchial carcinoma (= 15%
of all bronchial carcinomas) treated in our
clinic, 109 (20%) underwent thoracotomy and
94 (17%) resection. The recurrence free 3-
year survival rate for resected patients was
22%, and after 5 years 14 of the 94 (15%)
were still alive, using absolute numbers in-
cluding postoperative deaths. From 1962 to
1975 only patients in stage T1 NO M0 or T2
NO MO survived, with one survivor in stage
T1 N2 M0. In the period from 1976 to 1979
patients with tumors in more advanced stages
were resected: now those with T1 N1M0, T1
N2 MO and predominantly with T2 N1 M0 sur-
vived, which can be attributed to the effect
of more intensive chemotherapy. Sixty-eight
percent of the operations were
pneumonectomies; the exploratory thoracotomy
rate was 14%. Surgical therapy was seen as
