Pathologic analysis of 63 cases of brain metastases from lung was reported. The specimens of all cases were labelled by 4 antibodies (HLC3-AB, CEA, Keratin, GFAP), by means of ABC method. According to our data, brain metastases from lung accounted for 50.4% of whole brain metastases. Lobus frontalis was the most common intracranial metastatic site of lung cancer. Four histopathological types were classified: adenocarcinoma (55.6%), undifferentiated carcinoma (17.4%), adenosquamous carcinoma (14.3%) and squamous cell carcinoma (12.7%). The immunohistochemical results showed that HLC3-AB is a helpful marker in identifying brain metastases from lung cancer. GFAP showed negative in malignant cells but positive in stroma. This result suggested that the stroma of brain metastases contains ingredients originating from astro-gliofibre.

We measured pre- and postoperative CEA level in 330 patients who underwent resection for lung cancer at Kyushu Cancer Center Hospital between 1983 and 1986 using RIA method. There were 93 patients with high preoperative serum CEA level above 5 ng/ml. The interrelationships among preoperative serum CEA level, prognostic factors, outcome, and postoperative change of CEA level were investigated in the 93 patients. Five-year survival rate of patients with preoperative serum CEA level ranging from 5.0 to 10.0 ng/ml (N = 53) was 60.0%, while that of patients with preoperative CEA level over 10.1 ng/ml (N = 40) was 24.6% (P less than 0.05). Recurrent rate was higher in patients with preoperative CEA level over 10.1 ng/ml, especially in those with lung cancer at stages I or II. However, patients with preoperative CEA level about 50 ng/ml, showed good outcome after curative resection. All 12 patients in whom postoperative serum CEA level did not return to normal died within 4 years, indicating that normalization of CEA level is an important factor in prognosis. This study indicates that among lung cancer patients with high serum CEA level, the preoperative CEA level and postoperative change of CEA level are apparently prognostic factors.

A 58 year old housewife with tumor shadow in the right upper lung field on the chest X-ray was admitted. Marked swelling and severe arthralgia of both extremities and soft tissue clubbing of the fingers had been presented for two years prior to admission. The radiographs and bone scintigrams indicated proliferating periostitis along the long bones. Bronchofiberscope showed the obstruction of B2a of the right bronchus but the histological diagnosis was not established. Serum level of CEA and IAP were found to be high. Soon after the right upper lobectomy, arthralgia was significantly improved. The histological evaluation revealed a well differentiated adenocarcinoma of a primary lung cancer without mediastinal lymph node metastasis. Within 4 months the serum level of CEA and IAP normalized, the clubbing and the periosteal changes of the bones regressed.

During the period from 1978 to 1987, 30 cases of peripheral non-small cell lung cancer with primary lesions less than 2 cm in diameter were resected at our hospital. Histopathologically, these cases consisted of 24 adenocarcinomas, 5 squamous cell carcinomas and one adenosquamous carcinoma. Twenty-one cases were in early stages (p-stage I) and 9 in advanced stages (6 p-stage IIIA, one p-stage IIIB and 2 p-stage IV). Serum levels of CEA in the advanced stages exceeded those in the early stages. However, clinically no cases of the advanced stages are being assessed preoperatively. Thus, for cases of small peripheral lung cancer less than 2 cm, the possibility of advanced stages should be considered and for the complete cure of lung cancer, mediastinal lymph nodes dissection with lobectomy and appropriate adjuvant chemotherapy should be conducted.

Eighteen cases of non-small cell, small sized advanced lung cancer, out of 362 operated cases for 6 years excluding 7 cases of small cell lung cancer, 60 of preoperative treated and 27 of inoperable cases, were discussed. A small sized tumor was defined as a tumor within 8,000 mm3 in its volume, calculated by multipling three lengths measured on the resected specimens. There were fourteen cases with stage 3 and 4 (A), and four cases with N1 disease (B). In group A, three cases of twelve with N2 diseases showed the tiny skipping lesion in the mediastinum with negative regional nodes. Remaining two had a lesion of dissemination and pulmonary metastasis. In group B, they showed unusual way of N1 spread, in which two of them with left upper lobectomy had metastatic lymph nodes on the non-bearing lobe, the lower lobe, and other two cases took regional lymph nodes metastasis without invasive growth of the main tumor. Predominant histologic type was adenocarcinoma, but the subtype and the differentiation of it were not specific. The level of CEA was low below 5 ng/dl in most of them except three cases, in which it suggested massive positive nodes and pulmonary metastasis. Seven patients died of the disease in two years. Remainders are alive, 4 with and 7 free from the tumor with the longest period of 3 years and a half. N2 diseases of small sized tumor were found in the cases with the volume of 3 cm3 and more at almost same ratio.(ABSTRACT TRUNCATED AT 250 WORDS)

Cytochrome c from various sources, such as Candida krusei, yeast, horse, and cattle, was found to be recognized by human monoclonal antibody HB4C5 specific to lung cancer. Therefore, the cytochrome c was applied to the measurement of antibody amount in patient sera with a similar reactivity to the antibody HB4C5 for serodiagnosis of cancer. The cytochrome c from Candida krusei was most valuable for the serodiagnosis of various cancers, and the yeast cytochrome c was also useful. However, horse and bovine cytochrome c did not react with antibody of the cancer patients. By using Candida cytochrome c lung, bile duct, esophagus, and liver cancers were detected at high rates of more than 50%. In the case of lung cancer, the detection rates of small-cell, squamous, large-cell and adenocarcinoma were 78%, 63%, 100%, and 34%, respectively. The rate for small-cell carcinoma was higher than that with the currently used NSE assay system, and the rate for squamous carcinoma was comparable to that with the SCC assay system, although the system using cytochrome c did not show similar reactivity to that with the SCC system. Furthermore, lung cancer was detected at early stages by using cytochrome c, and even in the case of adenocarcinoma, the rate at early stages with the cytochrome c system was higher than that with the CEA assay system. On the other hand, false positive rates of benign diseases and normal were low--8% and 2%, respectively.

Using the indirect immunofluorescent assay, we observed the variation of T-lymphocyte subsets of peripheral blood in 100 patients of primary bronchogenic carcinoma and 31 cases with active pulmonary tuberculosis. Serum CEA were measured simultaneously. The decrease of OKT3+, OKT4+, OKT8+ lymphocytes were significant in patients with lung cancer than that in healthy controls (P less than 0.01). The ratio of OKT4+/OKT8+ increased. It suggested that both cellular immunoincompetence and immunoregulatory abnormality were present in patients with lung cancer. After the resection of tumors 65 cases, the percentage of OKT4+ cells increased at the first week. Fourty seven cases were observed continuously for six months, it was found that OKT8+ cells increased (P less than 0.01). After anticancer chemotherapy, the patients with small cell carcinoma revealed a similar changes too. After operation and chemotherapy, serum CEA level decreased significantly too.

Serum levels of CA-50, SLX and ST-439 were measured in 213 patients with lung cancer (92 adenocarcinomas, 63 squamous cell carcinomas, 37 small cell carcinomas and 21 large cell carcinomas) and 87 patients with benign lung disease. The overall positive rates in patients with lung cancer were 12.8% for CA-50, 29.7% for SLX and 25.3% for ST-439. The positive rates for CA-50, SLX and ST-439 in adenocarcinoma patients were 22.8%, 42.4% and 38.0%, respectively. Of the patients with benign lung disease, 4.8% were false positive for CA-50, 15.3% for SLX and 3.6% for ST-439. In the patients with adenocarcinoma of the lung, the combination assay of CEA and ST-439 had a highly accurate rate (61.9%).

Serum SLX, CEA, SCC and NSE levels were serially measured in 266 patients with lung cancer and compared with those in 345 patients with benign respiratory disorders (BRD). The positive rate for CEA in lung cancer (44.4%) and the false-positive rate in BRD (15.3%) were the highest among the 4 markers. The positive rate for SLX in lung cancer (32.0%) was lower than that of CEA, while the false-positive rate for SLX in BRD (7.2%) was lower than that of CEA. The positive rate for SLX was highest in adenocarcinoma and correlated better with the clinical stages than did CEA. SCC and NSE were specifically elevated in squamous cell carcinoma and small cell carcinoma, respectively. Using these 4 markers, only 70.2% of patients were correctly diagnosed as having lung cancer or BRD. In monitoring treatment effect, only SLX showed a statistically significant correlation with regression and progression in adenocarcinoma, while NSE and SLX showed such a correlation in small cell carcinoma. Serum tumor markers seem to be less sensitive for the diagnosis of lung cancer than chest X-ray and sputum cytology, indicating that a search for more specific markers is still required. However, in monitoring treatment effect, SLX appeared to be suitable for adenocarcinoma, while NSE and SLX seemed to be useful in small cell carcinoma.

The relative usefulness of a combination of some tumor markers, such as CEA, AFP, ferritin and NSE for the diagnosis of lung cancer was assessed by multiple logistic analysis. Serum concentration of these markers was determined in 68 patients with lung cancer (50 with NSCLC and 18 with SCLC, in 68 patients with benign lung disease and 75 normal control subjects. Ferritin proved to be the most useful in diagnosing both NSCLC and SCLC, while NSE was found to be of some help in diagnosing SCLC only. The multiple marker panel proved to be more sensitive and specific than any single marker in discriminating lung cancer from normal control tissue, but it was of limited value in discriminating malignant from benign lung disease. The results of the present study would suggest that the panel of investigated tumor markers is not of great help for the early diagnosis of lung cancer.
