Abstract
NSIP associated with primary lung cancer has been rarely reported. In the present report, three cases of histologically proven non-specific interstitial pneumonia (NSIP) associated with primary lung cancer are described. Importantly, in our 3 cases, interstitial pneumonia which is histologically proven to be NSIP was observed diffusely in both lungs. NSIP in these 3 cases responded to steroid therapy. However, 2 patients died from primary lung cancer and 1 patient died from progression of the interstitial pneumonia. Although the association between lung cancer and NSIP has been rarely documented, this combination was considered to be one of the paraneoplastic phenomena. The possible association between primary lung cancer and NSIP is discussed.

Abstract
The role of non-platinum combination chemotherapy in the treatment of advanced non-small-cell lung cancer (NSCLC) has not yet been clarified. In this phase I study, the dose-limiting toxicity (DLT), the maximum tolerable dose (MTD) and the antitumor activity of a two-drug combination of docetaxel (DCT) and irinotecan (CPT) in patients with advanced NSCLC were evaluated. Previously untreated patients with NSCLC in stage IIIB with malignant pleural effusion or stage IV were eligible. Both drugs were administered by 1-h intravenous infusion on day 1, and repeated every 3 weeks. DCT was given before CPT administration. Five escalating dose levels of DCT/CPT (40/135, 50/135, 50/150, 60/150, and 60/165 mg/m2) were studied. Eighteen patients received 44 courses. The DLT was considered to be neutropenia, because grade 4 neutropenia lasting for 3 days or more was observed in three patients, which was accompanied with three episodes of febrile neutropenia. As a non-hematological toxicity, grade 3 diarrhea occurred in three patients. Since all the three patients treated at the fifth dose level (DCT at 60 mg/m2 and CPT at 165 mg/m2) experienced DLT (grade 4 neutropenia in two patients and grade 3 hepatic toxicity in one), this dose level was determined to be the MTD. The objective response rate was 33.3%, and the median survival time was 13.6 months. To confirm the effectiveness of this combination for advanced NSCLC which was suggested in the present study, a phase II study with the recommended doses (150 mg/m2 for CPT and 50-60 mg/m2 for DCT) is warranted.

Abstract
To improve the efficacy of a combination of cisplatin and etoposide and concurrent accelerated twice-daily thoracic radiotherapy against limited-stage small-cell lung cancer, we conducted a phase I/II study using an altered schedule of chemotherapy administration. Chemotherapy consisted of four cycles of cisplatin (days 1 and 8) and etoposide (days 1, 2, 8, and 9) every 4 weeks. Accelerated hyperfractionated thoracic radiation (1.5 Gy twice daily x 30 fractions, total dose of 45 Gy) was concurrently given with the first cycle of chemotherapy. The recommended doses of cisplatin and etoposide determined in the phase I study were 40 and 80 mg/m(2), respectively. In the phase II study, the overall response rate was 100% (complete response: 32%, partial response: 68%). By a median follow-up time of 29 months, median radiation-outfield progression-free survival was 13.4 months, while radiation-infield progression-free survival did not reach median value. The median overall survival time was 22.9 months, with survival rate of 48.4% at 2 years. Major toxicities were leukopenia and neutropenia (>/=grade 3, 92% each). The local control and overall survival demonstrated in this study were excellent. However, the insufficient distant control suggests a need for development of more active chemotherapy regimens.

Abstract
When the development of chemotherapeutic agents reaches the clinical trial stage, it is necessary to perform drug sensitivity tests quickly in order to select the most promising agents for the treatment of cancer. In order to assess the possibility of using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay as a substitute for the human tumor clonogenic assay (HTCA), we evaluated the correlation between the results obtained by these 2 assays in 5 human lung cancer cell lines. The correlation coefficient between the results of the HTCA and the MTT assay was 0.673, indicating a relatively good correlation. The correlation was most prominent in platinum analogues (r = 0.939) and good in anthracyclines/anthracenedione (r = 0.611). However, no significant correlation was observed in vinca alkaloids, etoposide, irinotecan, SN-38 (an active metabolite of irinotecan), and rhizoxin. The results of the MTT assay showed a high degree of correlation with those of the HTCA in predicting the sensitivity of cancer cell lines to platinum analogues, and anthracyclines/anthracenedione. These results suggest that the MTT assay may be more convenient and quickly performed than the HTCA and can replace HTCA in evaluating the effects of anticancer agents, especially the platinum analogues and anthracyclines/anthracenedione.

Abstract
A 70-year-old man with small cell lung cancer was admitted to our hospital. He received chemotherapy consisting of cisplatin plus etoposide with concurrent chest irradiation. Because the patient had leukocytopenia after the first course of chemotherapy, he was treated subcutaneously with filgrastim (human recombinant granulocyte colony stimulating factor, G-CSF). Three days later, he developed psoriasiform skin eruptions mainly on the surface of the chest radiation field. When filgrastim was replaced with lenograstim (G-CSF), the skin lesions improved. But, after a second course of chemotherapy, lenograstim caused generalized psoriasiform eruptions. The patient had no previous history of psoriasis or any pre-existing skin disease. A skin biopsy revealed a Munro microabscess and spongiform pustules of Kogoj, which are the findings characteristic of the pathology of psoriasis. The MEDLINE report search has revealed, this is the first report of induction of psoriasis by G-CSF in a patient with small cell lung cancer.

Abstract
A 73-year-old woman was admitted to our hospital with a low-grade fever, dry cough and dyspnea on exertion as the chief complaints. She had been a professional shiitake mushroom grower for 50 years. Three years before visiting our hospital, she had been suspected of having hypersensitivity pneumonitis as a result of chest X-ray examination, bronchoalveolar lavage and transbronchial lung biopsy performed at another clinic. No antigens were identified at that time, but prednisolone was administered. On admission to our hospital, chest radiography and chest computed tomography revealed an interstitial shadow with subpleural honey-combing in both lower lung fields. After steroid pulse therapy, dyspnea on exertion and hypoxia improved moderately. Because of recurrence of the dyspnea, however, she was admitted on four separate occasions. On the second admission, an increase in lymphocytes was found by bronchoalveolar lavage, and septal lymphocytic infiltration accompanying fibrosis was demonstrated by transbronchial lung biopsy. On the fourth admission, a detailed immunological examination and an environmental survey were performed. The environmental provocation test yielded clinical symptoms similar to those experienced at the mushroom farm. Furthermore, tests of precipitation and lymphocyte proliferation in response to shiitake mushroom extracts were positive. Finally a diagnosis of chronic hypersensitivity pneumonitis induced by shiitake mushrooms was confirmed.

Abstract
A combination chemotherapy of irinotecan (CPT-11) and cisplatin (CDDP) has been reported to be active for lung cancer. In the previous trial, however, diarrhoea and leucopenia became the major obstacle for sufficient dose escalation of CPT-11 to improve the treatment outcome. We conducted a phase I study to investigate whether the fractionated administration of CDDP and CPT-11 at escalated dose was feasible and could improve the treatment outcome. Twenty-four previously untreated patients with unresectable non-small-cell lung cancer (NSCLC) or extensive disease of small-cell lung cancer (SCLC) were eligible. Both CDDP and CPT-11 were given on days 1 and 8, and repeated every 4 weeks. The dose of CDDP was fixed at 60 mg m(-2) and given by 1-h infusion before CPT-11 administration. The starting dose of CPT-11 was 40 mg m(-2), and the dose was escalated by an increase of 10 mg m(-2). The maximally tolerated dose of CPT-11 was determined as 60 mg m(-2) because grade 4 haematological or grade 3 or 4 non-haematological toxicities developed in six patients out of 11 patients evaluated. Diarrhoea became a dose-limiting toxicity. The objective response rates were 76% for NSCLC and 100% for SCLC. The recommended dose of CPT-11 and CDDP in a phase II study will be 50 mg m(-2) and 60 mg m(-2) respectively.

Abstract
Bone mass, bone metabolic markers, and calcium regulation hormones were measured in members of an Antarctic wintering team who stayed at the Japanese Antarctic station, Syowa (latitude: south 69 degrees 00', longitude: east 39 degrees 35') for 1 year. Subjects included 31 healthy Japanese males, aged 24-51 years (mean age 34.5 years) at the beginning of this study, ingesting 488 IU/day of vitamin D and 550.9 mg/day of calcium per person. The long-term coefficient of variation (CV) of the equipment used in the assessments of bone mass was 0.67% in single X-ray absorptiometry (SXA), 0.17% in the speed of sound (SOS) by quantitative ultrasound method (QUS), and 0.63% in broadband ultrasound attenuation (BUA) by QUS. The seasonal changes in the calcaneal bone mineral density (BMD) by SXA were not significant, whereas the SOS measured by QUS decreased during the measurement period (0.55%, p < 0.001), and BUA increased (1.9%, p < 0.01). Bone-specific alkaline phosphatase and osteocalcin levels increased significantly during summer (p < 0.001) and urinary calcium level decreased significantly during winter (p < 0.05). Urinary pyridinoline and deoxypyridinoline levels decreased significantly at the end of winter (p < 0.001). Serum 1,25(OH)2D3 level did not change significantly, whereas serum 25(OH)D3 level decreased significantly during winter (p < 0.001). Serum parathyroid hormone (PTH) level significantly increased at the end of winter (p < 0.01), although both PTH level and 25(OH)D3 level remained within the normal range. We concluded that the 25(OH)D3 level in subjects who stayed in Antarctica for 1 year decreased significantly with the reduction in duration of sunshine, but there were no clear changes in bone mass.

Abstract
Cardiac tamponade as an initial manifestation of primary lung cancer is uncommon. All such cases had shown symptoms of cardiac tamponade at the first visit of the hospital. We report a case of lung cancer with pericardial effusion without cardiac tamponade. Echocardiography, revealed little pericardial effusion and it has not increased for 3 months. Pericardiotomy revealed adenocarcinoma and lung cancer was confirmed by bronchial biopsy. It is necessary to further examine patients with even slight amounts of pericardial effusion.

Abstract
Seventeen cases of benign asbestos pleurisy were evaluated clinically. All cases were male and almost all cases were more than 60 years-old. Most cases presented with chief complaints of chest pain and dyspnea, but 2 cases had no complaints. Pleural effusion appeared predominantly in the right side. Six cases had 2 or 3 episodes of pleural effusion, and 1 case had 5. Ten cases had an occupational history of asbestos exposure in shipyards and 5 other cases had a history in building construction. Almost all cases had more than 30 years of exposure to asbestos and benign asbestos pleurisy appeared after more than 30 years from the first exposure to asbestos. Among the patients, 6 cases had diffuse pleural thickening and 2 cases had malignancies. Pleural fluid was bloody in 14 of 17 cases (82%) and all pleural fluid showed an exudate. Lymphocytes represented 70% and eosinophils 15% of the cellular population of the pleural fluid. Hyaluronic acid in pleural fluid in cases of benign asbestos pleurisy averaged 29.5 micrograms/ml, which was significantly (p < 0.05) lower than in malignant pleural mesothelioma. Leukocytosis in peripheral blood and a high CRP value were uncommon in benign asbestos pleurisy.

Abstract
201T1 single photon emission computed tomography (201T1 SPECT) was used to evaluate 18 patients with large opacities due to silicosis and 22 others with bronchogenic carcinoma. An early scan and a delayed scan were obtained and the retention index was calculated from the early ratio and the delayed ratio. In patients with silicosis, the retention index and the two ratios were significantly lower than in the patients with bronchogenic carcinoma (p < 0.01). In patients with stable shadows on chest X-ray films due to large opacities of silicosis, the delayed ratio was the same as or lower than the early ratio. However, in patients with silicosis who had high activity in large opacities, the delayed ratio was higher than the early ratio. These results suggest that 201)T1 SPECT is useful for evaluating the activity of large opacities in patients with silicosis and for differentiating large opacities caused by silicosis from those caused by bronchogenic carcinoma.

Abstract
The acute respiratory distress syndrome developed twice within 4 months in a patient with liver cirrhosis and diabetes mellitus. The diagnosis was made from the diffuse alveolar shadows seen on a chest X-ray film and a lung injury score of 3.3. The initial episode resolved quickly with steroid pulse therapy. The second episode resolved to some extent after the same therapy, but the patient died of hepatic and renal failure followed by acute pneumonia. The causes of the first and second episodes were considered to be different and the outcome depended on liver and kidney function. We report this case because the acute respiratory distress syndrome rarely occurs within 4 months.

Abstract
Monoclonal antibodies were raised against urine proteins from diabetic patients. An antibody, YO-2, stained three protein bands with apparent molecular weights of 66, 49, and 36 kDa. These bands were not reactive with an anti-human albumin antibody. The urine levels of YO-2-reactive antigen in the normal control were 0.97 +/- 0.37 U/g-Cr (units per gram of urine creatinine) (mean +/- SD). Those of the normo-, micro-, and macroalbuminuric diabetic patients, respectively, were 1.38 +/- 1.36, 2.87 +/- 2.07, and 3.92 +/- 3.33 U/g-Cr. They were significantly higher in the micro- and macroalbuminuric patients. The urine levels of YO-2-reactive antigen had no significant correlation with the urine albumin levels and hemoglobin A1c. We concluded that; a) monoclonal antibody YO-2 recognized a non-albumin urine antigen increasingly excreted in diabetic patients with nephropathy, b) recent glycemic control of diabetes would not significantly affect the urinary excretion rate of YO-2-reactive antigen, and c) the excretion rate and probably the mechanism of YO-2-reactive protein differed from those of albumin. The urine levels of YO-2-reactive antigen could be a clinical marker of diabetic nephropathy.

Abstract
BACKGROUND Malignant transformation of cells is associated with the change in their carbohydrate antigens. Sialyl-Lewisx (SLEX) is a necroinflammation-associated carbohydrate antigen (NICA) of liver cells, because it is newly expressed in chronic inflammatory liver diseases. The authors addressed whether this type of carbohydrate antigen shows cancer-associated changes. METHODS Expression of SLEX and its related structures was studied immunohistochemically using the well characterized monoclonal antibodies in 13 small and 6 advanced hepatocellular carcinomas (HCC). RESULTS SLEX was negative in 7 small HCC, which were well differentiated histologically. Both negative and positive cells were observed in 6 other small HCC. When positive, SLEX was expressed membranously or cytoplasmically. The membrane positive HCC cells were well differentiated. Cytoplasmic expression was observed in the less differentiated cells. The SLEX-negative cells were associated with any degree of differentiation. In six advanced HCC, the expression of SLEX could also be correlated with their histologic differentiation. HCC expressed sialyl-type 2 chain N-acetyllactosamine (2-NAcLc), but not 2-NAcLc, Lewisx, and Lewisy. CONCLUSIONS SLEX, a NICA, showed HCC-associated changes that were dependent on the levels of HCC cell differentiation. Suppression and reactivation of alpha 1-3fucosyl-transferase was a possible enzymatic basis for the observed changes.

Abstract
Human gastric surface epithelial cells display the ABH blood group antigens with the core structure of N-acetyllactosamine (NAcLc). Their expression is under the control of the secretor gene Se. The Thomsen-Friedenreich (T)-antigen (Gal beta 1-3GalNAc) is another core structure of the ABH antigens. We examined the gastric surface epithelial expression of T- and alpha 1-2 fucosylated T (FucT) histochemically with peanut agglutinin (PNA) and monoclonal antibody (MAb) MBr1, respectively. Eight of 24 individuals exhibited the PNA-reactive antigen (i.e., T-expressers) and others the MBr1-reactive antigen (i.e., FucT-expressers). alpha-L-fucosidase digestion of the FucT-positive tissues and beta-galactosidase digestion of the T-positive tissues, respectively, made them reactive with PNA and the antibody specific for GalNAc alpha-O-Ser/Thr. There was a remarkable correlation among reactivities with MBr1, Ulex europaeus lectin 1 (UEA1), and anti-Leb MAb CO-431. ABH blood group status had no correlation with this expression. We conclude that human gastric surface epithelial cells constitutionally synthesize T in alpha configuration (i.e., Gal beta 1-3GalNAc alpha-O-Ser/Thr) and that it was alpha 1-2 fucosylated only in the FucT-expressers. alpha 1-2 fucosylation of T is suggested to be regulated by the Se gene.

Abstract
Antitumor activities of five platinum analogs, including cisplatin, carboplatin, 254-S, DWA2114R, and NK121, were compared using five human lung cancer cell lines and 19 tumor specimens obtained from lung cancer patients. The antitumor activity was evaluated by determining the ratio of the maximum tolerated dose of each drug to the 70% tumor growth inhibitory concentration in a colony assay. Cisplatin was the most potent agent, followed by 254-S and carboplatin. DWA2114R and NK121 were less potent than cisplatin and 254-S. Cross-resistance to adriamycin was also investigated using an adriamycin-resistant small cell lung cancer subline, SBC -3/ADM30. SBC-3/ADM30 was 1.7- to 4.0-fold more resistant to cisplatin, carboplatin, NK121, and DWA2114R, than was the parent line, SBC-3, and the subline was 2.0-fold more sensitive to 254-S. Using SBC-3, in vitro combination effects of etoposide and cisplatin, carboplatin, or 254-S were evaluated by the median-effect principle. Synergism was noted when cisplatin and etoposide were combined at a fixed molar ratio of 1:1. Combination of carboplatin and etoposide showed an additive effect. The combination of 254-S and etoposide was antagonistic at low concentrations, but was markedly synergistic at higher concentrations. These data suggested the efficacy of 254-S in the treatment of lung cancer.

Abstract
We report here a case of hepatocellular carcinoma (HCC) with multiple lung metastases, which were disappeared by treatment of OK-432. The patient was a 65-year-old man and was diagnosed in 1986 with a small (17 x 11 mm) HCC in the anterior-superior segment of the liver. A part of the right hepatic lobe including the tumor was surgically removed, and transarterial injections of adriamycin (10 mg/week) and subcutaneous injections of OK-432 (10 KE/week) were given. Two and a half years later, recurrence of HCC in the liver and its invasion to vena cava inferior (IVC) were found. OK-432 administration was then stopped and percutaneous ethanol injection therapy (PEIT) was performed 10 times. Six months later, the PEIT was effective and the liver tumor with IVC invasion diminished. However, multiple lung metastases were visible on roentgenograms of the chest, and serum alphafetoprotein (AFP) concentration increased to 50,000 ng/ml. The OK-432 treatment resumed. After 6 months of OK-432 treatment, the multiple lung metastases were disappeared and the serum AFP level decreased to 100 ng/ml. At present, the patient is surviving without any sign of recurrence in either the liver or the lung. The clinical course of this case suggests that OK-432 might have effectively treated lung metastases of HCC, although the exact mechanisms are at present unclear.

Abstract
We evaluated the long-term outcome of 148 patients with small cell lung cancer (SCLC) who had been entered into clinical trials of chemotherapy with or without thoracic and prophylactic cranial irradiation (PCI) between 1981 and 1987. Eighteen patients (12%) survived for 2 or more years. With a minimum follow-up of 4.5 years, 10 of the 18 patients who remained disease-free at 2 years are currently alive and free of SCLC. Seven of these 10 patients currently function as they did before diagnosis. However, three suffer from central nervous system changes of varying degrees in severity which appeared 2-3 years after PCI. Eight of the 18 patients who were disease-free at 2 years have died. Two died of isolated relapse in the brain at 3.6 and 4.2 years after initiation of chemotherapy. Five died of other malignancies while continuing their complete response to SCLC; two of non-small cell lung cancer, two of acute myelogenous leukemia, and one of hepatocellular carcinoma. Another patient died of an unrelated disease without any evidence of SCLC. A small but substantial proportion of patients who underwent intensive treatment will achieve long-term survival; however, these patients remain at higher risk for second cancers and late toxicities. Therefore, attention must be directed to defining the safest way to employ such treatment in the management of SCLC.

Abstract
Using reverse transcription polymerase chain reaction, we determined mRNA expression of topoisomerase (topo) II alpha and beta in adriamycin- and etoposide-resistant small cell lung cancer sublines, SBC-3/ADM 100 and SBC-3/ETP. The expression of topo II alpha mRNA decreased substantially in SBC-3/ADM 100 and SBC-3/ETP as compared with the parent cell line, SBC-3; 0.71-fold in the former and 0.38-fold in the latter. Similarly, that of topo II beta mRNA decreased to an extent of 0.68-fold in SBC-3/ADM 100 and 0.28-fold in SBC-3/ETP as compared with the parent cell line. SBC-3/ADM 100 and SBC-3/ETP were highly resistant to topo II inhibitors such as daunorubicin, epirubicin, pirarubicin, mitoxantrone, and teniposide. However, SBC-3/ADM 100 showed a less resistance to aclarubicin, and SBC-3/ETP was as sensitive to the drug as was in the parent cell line. The resistance to topo II inhibitors excluding for aclarubicin might be partially explained by the decreased expression of topo II alpha and beta mRNA.

Abstract
Between April 1981 and December 1987, 148 patients with newly diagnosed small cell lung cancer (SCLC) were treated using combination chemotherapy with or without thoracic irradiation and prophylactic cranial irradiation (PCI) in a series of cooperative therapeutic trials. With a minimum follow-up of 4.7 years, 13 (9%) patients survived and were free of SCLC. These included 11 (15%) of 76 patients with limited disease and two (3%) of 72 patients with extensive disease. Three died without any evidence of SCLC (one each from second leukemia, non-small cell lung cancer, and unrelated disease). The remaining 10 (7%) patients are currently alive and free of SCLC beyond 4.7 years. Since late relapse beyond 5 years is a very rare event, these patients may have been cured. However, late toxicity of PCI must be kept in mind. Three among the 10 patients have suffered from neuropsychologic symptoms of varying degrees in severity. Although the long-term survival rate is a benchmark in the treatment of SCLC, modifications of therapy that may potentially avoid such toxicities should be considered hereafter.
