The CA 50 levels in serum samples from 440 patients were estimated using a dissociated enhanced lanthanide immunofluorimetric assay. The distribution was similar to CA 50-RIA assays. Raised levels (greater than 14 U/ml) were present in 95% pancreatic cancer, 68% hepatoma, 54% advanced colorectal cancer, 58% advanced breast cancer and 48% lung cancer. High values were observed in adenocarcinoma of the lung, and were related to tumour mass in small cell lung cancer. CA 50 is independent of CEA. The marker is of considerable potential in pancreatic cancer where the majority of patients express the Can 50 Ag.

To identify risk factors for adenocarcinoma of the lung, a population-based case-control study of 336 female cancers of this cell type and an equal number of neighborhood controls was conducted between 1983 and 1986. After adjusting for personal smoking, personal and family histories of lung disease emerged as additional risk factors. A personal history of any lung disease was associated with a 40% increase in risk [smoking adjusted relative risk (SARR) = 1.4, 95% confidence interval (CI) = 1.0, 2.0] with a more marked increase in risk for lung diseases occurring during childhood (SARR = 1.9, 95% CI = 1.2, 3.2) and for tuberculosis (SARR = 10.0, 95% CI = 1.1, 90.1). Family histories of tuberculosis (SARR = 2.0, 95% CI = 1.1, 3.6) and of lung cancer (SARR = 3.9, 95% CI = 2.0, 7.6) were also risk factors for adenocarcinoma of the lung. Increasing risk was observed with decreasing intake of dietary beta-carotene. After adjusting for personal smoking, women in the lowest quartile of intake showed a two-fold increased risk relative to those in the highest quartile of intake (P = 0.003). There were also some suggestive differences between cases and controls in their reproductive history and hormone use.

The first patient to respond to [(glycolato-0,0') diammineplatinum (II)] (254-S) in a clinical phase I study is reported. The patient was a 52-year-old man complaining of nausea and weight loss. A chest X-ray demonstrated a diffuse infiltrating shadow in the right lung. A transbronchoscopic brushing of the right upper lobe and a biopsy specimen from the right supraclavicular lymph node revealed adenocarcinoma of the lung. He was diagnosed as having primary lung cancer with distant lymph node metastasis. 254-S was administered by intravenous drip infusion to a dose of 100 mg/m2. Two weeks after the second 254-S treatment, a chest X-ray demonstrated a more than 50% reduction in the pulmonary shadow and met the WHO criteria for a partial response. Thrombocytopenia, leukocytopenia and moderate nausea were observed as adverse effects of 254-S but renal toxicity was not found. Pharmacokinetics of free platinum in this patient demonstrated biphasic decay with a peak plasma concentration of 8.09 micrograms/ml. A disease-oriented phase II study of 254-S against non-small cell lung cancer should be performed to establish the efficacy of this new platinum complex.

Eighty-nine primary lung carcinomas and 23 metastatic lung tumors were immunohistochemically studied for the expression of pulmonary surfactant apoproteins, by using monoclonal (PE-10) and polyclonal antibodies. Surfactant apoprotein was demonstrated in the cytoplasm and/or nuclear inclusion bodies of only primary lung adenocarcinomas (36 of 75 cases), not in any other histologic type of primary lung carcinoma or in metastatic lung tumors. In primary lung adenocarcinoma, although typical type II pneumocyte type adenocarcinoma was not included in the current series, the majority of surfactant apoprotein-positive single cell type tumors were of the Clara cell type, with a single bronchial surface epithelial cell type, according to the light microscopic subclassification of adenocarcinoma cells. The Clara cell type adenocarcinomas could at times be distinguished only with difficulty from adenocarcinoma of type II pneumocyte type. Normal and hyperplastic type II pneumocytes were of course positive for surfactant apoprotein in the cytoplasm. However, none of the positive cells could definitely be identified as Clara cells in non-neoplastic lungs. The findings obtained in this study indicate that surfactant apoprotein is a good marker to distinguish adenocarcinoma of the lung from other histologic types of lung cancer and from neoplasms metastatic to the lung, and that type II pneumocytes and Clara cells, non-neoplastic and neoplastic, are morphologically and functionally closely related and might belong to the same cell lineage.

The prognostic impact of subtyping pretreatment histologic material in adenocarcinoma of the lung (ACL) according to WHO was evaluated in 259 consecutive, inoperable, Stage III patients. One hundred thirty patients (50%) had acinar adenocarcinoma, 23 (9%) had papillary adenocarcinoma, 13 (5%) had bronchioloalveolar carcinoma, and 32 (12%) had solid carcinoma with mucus formation; five patients (2%) had other types of lung cancer. Subtyping was impossible due to cytology or insufficient histologic material in 56 patients (22%). Bronchioloalveolar carcinoma had the longest median duration of response to chemotherapy (47 weeks), time to progression (33 weeks), and median survival (40 weeks). Corresponding values for solid carcinoma with mucus formation were 8, 12, and 22 weeks. Acinar and papillary adenocarcinoma were intermediate. Survival curves and response rates were similar (P greater than 0.05). Bronchioloalveolar carcinoma had 46% 1-year survivors compared to 16% to 22% for other subtypes. The subtypes may have an impact on the prognosis of ACL, but further evaluation is required.

Malignant tracheoesophageal fistula occurs infrequently in patients with irradiated esophageal and lung cancer, uncommonly in patients with untreated mediastinal malignancies, infection, or trauma, and rarely in primary adenocarcinoma of the lung. The natural progression of this entity leads to rapid deterioration and death from overwhelming pulmonary infection.Definitive treatment depends on the demonstration and localization of the fistula. Computerized tomography (CT) chest scanning with dilute oral contrast is the ideal means of identification of the fistula. CT scanning without contrast may outline sufficiently the pathology to avoid the usage and side effects of contrast media in the lungs.A review of one case of tracheoesophageal fistula due to pulmonary adenocarcinoma is presented where emergency CT scanning without contrast resulted in rapid and accurate diagnosis, leading to prompt and appropriate management.

We have described a patient who had a clinical picture of CREST syndrome and pulmonary interstitial fibrosis, and in whom adenocarcinoma of the lung developed over a four-year period. Despite absence in the literature of the association of lung carcinoma in patients with CREST syndrome, our case is an example of pulmonary fibrosis complicated by lung cancer without any evidence of other risk factors. We believe this to be the first report of such an association. Clinicians, therefore, must be aware that pulmonary interstitial fibrosis in patients with the CREST syndrome may represent a risk for lung cancer.

In vitro antitumor effects of human recombinant tumor necrotizing factor (rH-TNF) were examined against nine lung cancer cell lines including six non small and three small cell lung cancer, four stomach cancer cell lines and 30 freshly isolated lung cancer cell samples by the human tumor clonogenic assay. rH-TNF did not show any inhibitory effect on the colony formations of lung and stomach cancer cell lines, except for PC10 established from squamous cell carcinoma even at the high concentration. The overall response rate of fresh material was 11.5%. The colony formations of only two materials from 20 patients without prior chemotherapy were significantly suppressed by rH-TNF in vitro. Three specimens of adenocarcinoma exhibited more than 70% decrease in colony number by treating with 100 and 1000 u/ml of rH-TNF resulting in the response rate of 15.8% (3/19). From these results, it can be concluded that rH-TNF has modest direct cytotoxic effect on lung cancer, and additional study against adenocarcinoma of the lung might be warranted.

A high incidence rate of lung cancer with preponderance of adenocarcinoma in non-smokers has been reported in women of southern Chinese ethnic origin. Thirty-three southern Chinese female patients with primary adenocarcinoma of the lung, all lifelong non-smokers, were typed for HLA-A and B antigens to study the possibility of genetically determined susceptibility factors. The antigen frequencies were compared with those of 110 healthy controls. No significant difference in antigen frequencies was found in the patients compared with controls. Studies on other possible factors determining susceptibility to lung cancer in Chinese women are necessary.

The routine imaging work-up of suspected lung cancer should include posteroanterior and lateral chest radiographs and, in most cases, a computed tomographic (CT) scan of the entire thorax and adrenal glands. In asymptomatic patients with adenocarcinoma of the lung, there is justification for doing routine contrast-enhanced CT examination of the brain. Further imaging workup will be suggested by the patient's history, physical findings, and laboratory findings. Magnetic resonance imaging of the chest in patients with lung cancer is being investigated, but current studies comparing it with CT demonstrate no definite advantage at this time, with the possible exception of the lung apex in which T1 weighted thin-section coronal views are useful.
