The efficacy of combined high-dose etoposide with standard dose cisplatin was evaluated in patients who had refractory lung cancer after standard chemotherapy. Each patient was given etoposide at 500 mg/m2/day on day 1 to 3 continuously (total dose 1,500 mg/m2) and cisplatin at 80 mg/m2 on day 1. Fifteen patients (7 adenocarcinoma, 5 small cell lung cancer, 2 squamous cell lung cancer and 1 sarcoma, which latter was difficult to distinguish from giant cell carcinoma) were entered in this study. The overall response was 41.7% (5 of 12); five partial response, 6 no change, and 1 progressive disease. Three treatment-related deaths were observed; one resulted from sepsis and two from respiratory failure because of tumor progression. All of the patients developed severe myelosuppression; the mean nadir white blood cell count was 400, and the mean nadir platelet count was 24,000 in 28 evaluable courses. The range of maximum concentration of etoposide determined by HPLC was from 17.4 to 39.1 micrograms/ml. These results suggest that high-dose etoposide combined with a standard dose of cisplatin is effective against refractory lung cancer.

The aim of this study was to investigate anti-elastin antibodies of the IgG and IgM types in sera of patients suffering from lung cancer, using the DOT immunobinding assay. We studied 96 pathological and 40 control sera. Anti-elastin antibodies were found to be present in 45% of patients with small cell lung cancer, 19% of subjects with adenocarcinoma and not-identified lung tumor and 15% of patients with squamous cell lung cancer. They circulated in 5% of control persons only. The highest values of their titers were observed in the advanced stages of disease. In 55% of anti-elastin antibody positive small cell lung cancer patients, antibodies were of the IgM type, suggesting the initial step of the autoimmunization to elastin.

The aim of this clinically controlled trial was to assess the effect of different smoking patterns on development of different histological types of lung cancer. The study group consisted of 1,432 subjects that died due to lung cancer in the years 1980-1987. 627 of these had the histological type of the cancer determined; 54% had squamous cell cancer, 24% small cell lung cancer (SCLC), 17% adenocarcinoma. The control group consisted of 1,343 subjects that died due to other causes. Medical and social history was taken from the families of the deceased. The results of the analysis demonstrate that lung cancer development is related to smoking although differences were seen in the different types of cancer. The calculated risk of a smoker developing lung cancer-squamous cell and SCLC was respectively 15.4 and 13.5 while for adenocarcinoma it was much lower--3.1. Important differences were seen in ex-smokers developing squamous cell lung cancer and SCLC. The risk of developing squamous cell lung cancer and SCLC in this group was 89% and 88%, and adenocarcinoma only 64%. This suggests that adenocarcinoma is related more to environmental factors than the other two types of lung cancer.

A modified protocol was used in the treatment of inoperable nonmetastatic squamous cell lung cancer which consisted of three courses of induction chemotherapy with cisplatin, cyclophosphamide, lomustine and vincristine. Radiotherapy was delivered in multifractionated regime, daily two fractions of 1.5 Gy, 4 hours apart up to the total dose of 51 Gy. During 1985-1989, 77 patients were entered into the study. Twenty-six patients did not complete treatment, but were evaluated for the response rate and in survival analysis. There were 29 patients with Stage I and II, and 48 patients with Stage III lung cancer. After combined treatment CR was 15%, PR 39% and RR 54%. One- to four-year overall survival of 48 evaluable patients with Stage III were: 58%, 30%, 17% and 7%, respectively. The overall survival of the whole treatment group was significantly better than the survival of historical control group of 65 patients treated by radiotherapy only.

Numerous case reports have shown the advantage of using bronchoalveolar lavage (BAL) in cytologic diagnosis of primary and secondary malignant neoplasms of the respiratory system. The aim of this study was to determine the usefulness of BAL in the diagnosis of peripheral, primary lung cancer. Of 1,864 patients referred to the Bronchological Department for endoscopic examination, 145 patients were studied: six with large cell lung cancer, 22 with adenocarcinoma, 15 with alveolar cell lung cancer, 40 with small cell lung cancer, and 62 with squamous cell lung cancer. In 94 patients (64.8 percent), BAL was diagnostic, revealing malignant cells. In 52 (35.9 percent) of these patients, the cytologic diagnosis agreed with the final pathologic diagnosis of the resected tumor. The result of BAL was affected by the type of cancer and size of the tumor. Highest yields were seen in adenocarcinoma (59.2 percent) and alveolar cell lung cancer (80 percent). The average size of the tumor in the group with correct cell typing was 4.9 +/- 1.8 cm; in patients with nondiagnostic BAL, the average size was 2.6 +/- 1.2 cm. BAL provided the highest (statistically significant, p less than 0.05) diagnostic yield (64.8 percent) in comparison with other sampling techniques: brush biopsy (29.8 percent), catheter biopsy (26.8 percent), and forceps biopsy (32.7 percent). The diagnostic yield of BAL and transbronchial fine needle aspiration biopsy (58.3 percent) did not significantly differ. BAL proved to be a valuable diagnostic tool in detecting peripheral, primary, pulmonary malignant neoplasms.

Two cases of downhill esophageal varices associated with superior vena cava syndrome due to lung cancer are reported. Case 1 was a 68-year-old male with swelling of the upper right half his body. Chest X-ray film showed a mass shadow in the upper right lung field. Small cell lung cancer completely obstructed the superior vena cava. Esophagoscopy showed four striated downhill esophageal varices (F1, CB, RC(-]. After treatment with concurrent chemoradiotherapy, he had a partial response and the varices disappeared. Case 2 was a 55-year-old male with productive cough. The superior vena cava was narrowed by squamous cell lung cancer, with good collateral pathways. Three striated downhill varices (F1, CW, RC(-] were present. Concurrent chemoradiotherapy resulted in partial response, but the number of striated varices increased to four and CB, and extended downward. Left jugular venography revealed collateral veins to the esophagus, although bilateral brachial venography revealed no collaterals. Dynamic CT with bolus injection of contrast medium via the left jugular vein demonstrated esophageal varices. There are few reports on the blood flow of downhill esophageal varices.

Pulmonary resection remains the most effective treatment for patients with non-small-cell lung cancer. The purpose of this study is to determine the incidence, pattern, and site of lung cancer recurrence in patients surviving resection for non-small-cell lung cancer. One hundred ninety-eight patients with post-surgical non-small-cell lung cancer were followed up from 6.5 to 0.5 years (median: 2.0 years). Recurrent cancer developed in 103 patients (52.0%). Nineteen cases had local recurrence (9.6%) and 84 (42.4%) were distant metastasis. The incidence of recurrence increased with TN status, but there was no significant difference (P = 0.451) in the overall rate of recurrent lung cancer among the various TN staging. The overall recurrent rate of non-squamous cell lung cancer was 57.4%, which was higher than 47.7% in squamous cell lung cancer. Still, it made no significant difference among the various cell types (P = 0.058). Distant metastasis occurred most commonly to the bone (22.7%), then the contralateral lung (12.6%). Curative resection with accurate staging, appropriate adjuvant therapeutic modality and continued periodic surveillance are necessary in all patients who overcome the initial carcinoma.

Three interesting cases of primary lung cancer from the standpoint of tumor marker production were reported. The first was a case of double cancers, one of which was sigmoid cancer without CEA production and the other a large cell lung cancer with CEA production. The evidence of elevated serum CEA level initially led to a wrong diagnosis as sigmoid cancer with lung metastasis. The second was a case which showed a relapse of monotonous cancer without CEA production after surgical removal of lung cancer tissue containing heterogeneous cancer cells. Elevated serum CEA levels were never observed after the operation, although the preoperative serum test was positive for CEA. The last was a case of squamous cell lung cancer which showed trophoblastic differentiation accompanied with massive hCG production. Very rapid tumor cell growth was seen after the early relapse following the operation. Positivity for hCG staining varied among primary and metastatic tumor tissues.

Clinical evaluation of 32 cases of primary lung cancer treated with Bronchial Artery Infusion (BAI) were reported. As to the relationship between Bronchial Arteriogram (BAG) and therapeutic effect of BAI, the therapeutic effect of BAI was closely correlated with the degree of neovascularity. And as no correlation was shown between therapeutic effect and histology of lung cancer, the degree of neovascularity on BAG seemed to be more important factor. From the aspect of survival, neovascularity and B-P shunt on BAG showed no correlation with the survival time. On the relationship between survival and histology of lung cancer, squamous cell carcinoma and adenocarcinoma showed almost an equivalent survival. According to the stage of our cases, 25 out of 32 cases were stage III and IV, and they showed relatively better survival, especially stage III, of which MST was 16.6 months, and of which a two year survival rate was 33.5% considering MST and a two year survival rate of stage III A (N2) of non-resected non-small cell lung cancer in other reports are about 12 months and 20%, respectively. BAI is considered to be an effective method among several treatments against lung cancer.

Serum LSA and CEA levels were measured in 86 patients with lung cancer, 56 patients with benign pulmonary diseases and 127 normal subjects. The results showed that the diagnostic accuracy rate of LSA for lung cancer (82.4%) was higher than that of CEA (67.6%). LSA was more useful than CEA for diagnosis and differantial diagnosis of lung cancer. CEA was more sensitive to adenocarcinoma of the lung. While LSA was sensitive to small cell lung cancer and squamous cell lung cancer as well. LSA levels and positive rate were related to the stages of lung cancer. LSA was more helpful than CEA for evaluating the status of disease and staging patients. The changes of LSA levels in 33 patients with lung cancer were related to the results of chemotherapy. LSA was superior to CEA for monitoring therapy. Combinative determination of both two markers was better than that of single marker.
