Abstract
BACKGROUND We conducted this case-control study to evaluate smoking effect on lung cancer conditional on the level of exposure to cooking emissions and to explore whether there is a joint effect of these two risk factors. SUBJECTS AND METHODS We selected 279 newly diagnosed primary lung cancer cases and 322 community controls from Hong Kong females, frequency matched by age group, and collected relevant data. We applied logistic regression to estimate lung cancer risk related to smoking and cooking fume exposure, expressed as total cooking dish-years, while adjusting for various potential confounding factors. RESULTS Current smoking was associated with four-fold increased risk, and ex-smoking with two-fold risk, which was not much influenced by cooking dish-years. No increased risk was observed in environmental tobacco smoking. Increasing intakes of yellow/orange vegetables and multivitamins were significant protective factors in all models. In the analysis of joint effect, the combination of smoking and cooking dish-years tended to have a greater risk than exposure to cooking fumes alone. There was a dose-response gradient with total dish-years in nonsmokers, but not in smokers. Smoking was more strongly associated with nonadenocarcinoma, whereas exposure to cooking fumes appeared to be related to both adenocarcinoma and nonadenocarcinoma. CONCLUSION We confirmed the important roles of smoking and cooking emissions in lung cancer risk among the women. These two major risk factors appeared to act independently.

Abstract
Background This study used a large-scale cancer database in determination of prognostic factors for the survival of lung cancer subjects in Taiwan. Methods Total of 24,910 subjects diagnosed with lung cancer was analysed. Survival estimates by Kaplan-Meier methods. Cox proportional-hazards model estimated the death risk (hazard ratio (HR)) for various prognostic factors. Results The prognostic indicators associated with a higher risk of lung cancer deaths are male gender (males versus females; HR = 1.07, 95% confidence intervals (CI): 1.03–1.11), males diagnosed in later periods (shown in 1991–1994 versus 1987–1990; HR = 1.13), older age at diagnosis, large cell carcinoma (LCC)/small cell carcinoma (SCC), and supportive care therapy over chemotherapy. The overall 5-year survival rate for lung cancer death was significantly poorer for males (21.3%) than females (23.6%). Subjects with squamous cell carcinoma (SQCC) and treatment by surgical resection alone had better prognosis. We find surgical resections to markedly increase 5-year survival rate from LCC, decreased risk of death from LCC, and no improved survival from SCC. Conclusion Gender and clinical characteristics (i.e. diagnostic period, diagnostic age, histological type and treatment modality) play important roles in determining lung cancer survival.

Abstract
The mortality rate of lung cancer in Asian women has increased significantly in the past few decades. Environmental factors include tobacco smoke (active and environmental), other indoor pollutions (cooking oil vapours, coal burning, fungus spores), diet, and infections. Active tobacco smoking is not the major factor. The relative risk of lung cancer among non-smoking women ever exposed to environmental smoke from their husbands was 1.20 from a meta-analysis. Cooking oil vapours associated with high temperature wok cooking and indoor coal burning for heating and cooking in unvented homes, particularly in rural areas, are risk factors for Chinese women. Chronic benign respiratory diseases due to the fungus Microsporum canis probably accounts for the high incidence of lung cancer in northern Thai women at Sarapee. Diets rich in fruits, leafy green vegetables, and vitamin A are protective, while cured meat (Chinese sausage, pressed duck and cured pork), deep-fried cooking, and chili increased the risk. Tuberculosis is associated with lung cancer. Also, a Taiwanese study showed that the odds ratio of papillomavirus (HPV) 16/18 infection in non-smoking female lung cancer patients was 10.1, strongly suggesting a causative role. Genetic factors have also been studied in Chinese women, including human leucocyte antigens, K-ras oncogene activation, p53 mutation, polymorphisms of phase I activating enzymes (cytochrome P450, N-acetyltransferase slow acetylator status), and phase II detoxifying enzymes (glutathione-S-transferases, N-acetyltransferase rapid acetylator status). New molecular screening technology would facilitate identification of molecular targets for future studies. The interaction between environmental and genetic factors should also be further elucidated.

Abstract
BACKGROUND Recently, peripheral lung adenocarcinomas (PLA) measuring < or = 3 cm in greatest dimension often have been diagnosed using diagnostic radiology. The objective of the current study was to determine which cytologic factors are associated with a favorable outcome and an unfavorable outcome in patients with PLA. METHODS Imprint smears from 134 patients with PLA were examined. Sixteen cytologic factors, including necrosis, cellular distribution, overlapping of cell clusters, cluster aggregation, cluster size, cluster thickness, nuclear irregularity, nuclear size, variation in nuclear size, multinucleated cells, intranuclear inclusions, type of intranuclear inclusions, appearance of nucleoli, eosinophilic nucleoli, multinucleoli, and mitosis, were evaluated using univariate and multivariate analyses. A counting method was used to determine the prognosis for individual patients. RESULTS In the univariate analysis, a cluster size that measured > or = 831 microm in short dimension (P = 0.0011), moderate or severe nuclear irregularity (P = 0.0030), > or = 5 multinucleated cells per 100 tumor cells (P = 0.0047), moderate or severe variation in nuclear size (P = 0.0061), medium or large nuclear size (P = 0.0169), and > or = 1 mitotic cell per 100 tumor cells (P = 0.0412) were associated significantly with a poor outcome. In the multivariate analysis, cluster size in short dimension (P = 0.0018), multinucleated cells (P = 0.0066), and nuclear irregularity (P = 0.0310) were found to be independent prognostic factors. CONCLUSIONS The combination of cytologic features using intraoperative imprint smears, namely, cluster sizes < or = 830 microm in short dimension, < or = 4 multinucleated cells per 100 tumor cells, and mild nuclear irregularity, may provide favorable predictive information in patients with PLA.

Abstract
The 8-oxoguanine DNA glycosylase (OGG1) repairs DNA by removing 8-hydroxyguanine, a highly mutagenic oxidative DNA adduct. Recently, the gene for OGG1 was cloned and several polymorphisms have been reported. Because environmental carcinogens produce 8-hydroxyguanine residues that potentially cause oncogenic mutations by mismatching to this modified base, the capacity to repair these lesions can be involved in cancer susceptibility. This study investigated the association between OGG1 Ser326Cys polymorphism and risk of the lung adenocarcinoma for Japanese by a prevalent case-control study in Japan. The subjects comprised 138 cases and 241 non-cancer outpatients as controls. OGG1 gene polymorphism was genotyped by a PCR-CTPP (polymerase chain reaction with confronting two-pair primers) method. The distribution of OGG1 Ser326Cys genotype among controls (Ser/Ser, 28.3%; Ser/Cys, 49.2%; and Cys/Cys, 22.5%) was not different from that among cases (Ser/Ser, 29.0%; Ser/Cys, 51.4%; and Cys/Cys, 24.0%). The sex-age adjusted odds ratio (OR) was 1.06 with 95% confidence interval (CI) 0.64-1.76 for Ser/Cys genotype and 0.81 with 0.44-1.52 for Cys/Cys genotype. The ORs according to the interval between diagnosis and study enrollment were also examined because the polymorphism was a potential prognostic factor of lung cancer. The ORs of Ser/Cys and Cys/Cys genotypes in the cases less than 3 years after diagnosis were higher than overall ORs; 1.86 (95%CI, 0.91-3.77), and 1.46 (0.64-3.35), respectively. The OR for smoking was not statistically different among genotype, though the sample size was too small to detect even a moderate interaction. This study supported the first study by Sugimura et al (Cancer Epidemiol Biomarkers Prev, 1999; 8: 669-674), that the association of OGG1 Ser326Cys polymorphism was limited for the risk of lung adenocarcinoma.

Abstract
PURPOSE To evaluate the efficacy and toxicity of high-dose thoracic radiotherapy (TRT) alternating with chemotherapy (CH) for unresectable stage III non--small-cell lung cancer (NSCLC). PATIENTS AND METHODS Forty-one patients received TRT with 1.5 Gy twice daily, 5 days a week, on weeks 1, 2, 5, 6, and 9, up to a total dose of 66 to 72 Gy, alternating with cisplatin 80 mg/m(2) on day 1 and vindesine 3 mg/m(2) on days 1 and 8, repeated every 4 weeks, for two or three courses beginning on week 3. RESULTS The median (range) total dose of TRT and number of CH courses were 72 Gy (16.5 to 72 Gy) and three (zero to three), respectively. Delay in TRT > or = 5 days was observed in 24 (75%) of 32 patients who completed the projected treatment, due to leukopenia in 12, esophagitis in seven, infection in two, and other causes in three patients. Partial responses were obtained in 36 patients (88%). The median survival time and 3- and 5-year survival rates were 18.4 months, 24%, and 10%, respectively. Grade 3 or 4 leukopenia and esophagitis developed in 32 and seven patients, respectively. Grade 3 or 4 late esophageal toxicity developed in two patients. CONCLUSION Alternating high-dose TRT and CH for stage III NSCLC produced a high response rate with median and long-term survival comparable to prior trials utilizing standard approaches in this population. Acute and late esophageal toxicity was observed and interruption of TRT was required in most of the patients.

Abstract
The higher frequency of human lung adenocarcinoma in females than in males, strongly suggests the involvement of gender dependent factors in the etiology of this disease. This is the first investigation of estrogen receptor (ER) beta in human lung. Immunohistochemical staining revealed ERbeta expression in normal lung and in atypical adenomatous hyperplasia (AAH), considered as a precancerous lesion for adenocarcinomas. Adenocarcinomas showed significantly higher expression of ERbeta than squamous cell carcinomas. On the contrary, ERalpha expression was not detected in all cases. The functional integrity of ERbeta such as the binding ability to estrogen responsive element (ERE) and transcriptional activity was confirmed using a human lung cancer cell line, RERF-LC-OK. Colony formation of this cell was significantly reduced in the presence of pure antiestrogen. We conclude that ERbeta, but not ERalpha, is present in lung tissues with an important physiological function in normal lung. Furthermore, ERbeta may play a role in growth and development of adenocarcinomas.

Abstract
Many small adenocarcinomas can be detected as a result of recent advances in diagnostic radiology. Since the histological and biological heterogeneity of adenocarcinoma often makes it difficult to predict the outcome of operated patients, clarifying the morphological prognostic factors of the tumor is indispensable to the selection of appropriate treatment. We examined 200 cases of adenocarcinoma of the lung 3 cm or less in diameter (T1). Tumor size, tumor cell characteristics, growth pattern, characteristics of fibrosis, vessel and stromal invasion, and metastasis were evaluated to define favorable and unfavorable morphological prognostic factors by univariate and multivariate statistical analysis. There were no deaths in the 66 cases with more than a 75% of lepidic growth component defined as a region of tumor cells growing along alveolar walls and without stromal invasion, central focus of fibrosis 5 mm or less in maximum diameter, or no elastic fiber framework destruction by tumor cells. Multivariate analysis to investigate unfavorable factors revealed that vascular invasion (P<0.001) and a greater than 25% papillary growth component (P=0.043) were the most significant determinants of an unfavorable outcome. The favorable and unfavorable factors demonstrated in this study will be of great value in selecting the treatment of patients with small peripheral adenocarcinoma of the lung.

Abstract
The present study was undertaken to estimate the effect of 6-methylthiohexyl isothiocyanate (6MHITC) isolated from Wasabia japonica (wasabi) pretreatment on 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone(NNK)-induced lung tumorigenesis in mice. Pretreatment with 6MHITC for 4 consecutive days at a daily dose of 5 micromol significantly inhibited NNK-induced O(6)-methylguanine formation in lungs at 4 h after the injection. In conjugation with this inhibitory effect, 6MHITC suppressed the increase in proliferating nuclear cell antigen level as well as ornithine decarboxylase activity at a promotion stage of NNK-induced lung tumorigenesis. Finally, this treatment of 6MHITC suppressed the NNK-induced lung tumorigenesis in mice. These results suggest that 6MHITC inhibits the development of lung tumors in mice treated with NNK, due to the suppression of initiation stage.

Abstract
BACKGROUND A number of prognostic factors have been reported for resected nonsmall cell lung carcinoma. None of them, however, has been reported to have greater prognostic impact than the pathologic TNM staging system. The authors evaluated 18 conventional clinicopathologic prognostic factors in each pathologic stage. METHODS A retrospective study was conducted on surgically resected 836 lung carcinoma patients, and the following conventional prognostic factors were evaluated in multivariate analyses: age, gender, pack-year smoking, serum carcinoembryonic antigen and squamous cell carcinoma antigen levels, laterality of tumor, clinical N status, histologic type of tumor, greatest tumor dimension, grade of differentiation, pleural involvement, lymphatic invasion, vascular invasion, degree of fibrosing scarring, nuclear atypia, mitotic activity, and curativity of resection. RESULTS The overall 5-year survival rate was 63.8%. In 430 cases of pathologic Stage I disease, multivariate analyses revealed 3 significant prognostic factors: clinical N status (P < 0.001), vascular invasion (P = 0.001), and curativity of resection (P < 0.001). In 406 cases of more advanced disease, i.e., pathologic Stage II, IIIA, IIIB, or IV, multivariate analyses revealed 4 factors as significant: histology (P = 0.001), pathologic N status (P < 0.001), tumor size (P < 0.001), and curativity of resection (P = 0.002). CONCLUSIONS Conventional clinicopathologic prognostic factors had a different impact on prognosis in each pathologic TNM stage among patients who underwent surgical resection of nonsmall cell lung carcinoma. These factors should be analyzed separately in each pathologic TNM stage.
