The Impact

BACKGROUND: Lung cancer contributes significantly to cancer morbidity and mortality. Although case fatality rates have not changed significantly over the past few decades, there have been advances in the diagnosis, staging and management of lung cancer.OBJECTIVE: To describe the epidemiology of primary lung cancer in an Alberta cohort with an analysis of factors contributing to survival to two years.PATIENTS AND METHODS: Six hundred eleven Albertans diagnosed with primary lung cancer in 1998 were identified through the Alberta Cancer Registry. Through a chart review, demographic and clinical data were collected for a period of up to two years from the date of diagnosis.RESULTS: The mean age at diagnosis was 66.5 years. The majority of cases (92%) were smokers. Adenocarcinoma, followed by squamous cell carcinoma, were the most frequent nonsmall cell lung cancer histologies. Adenocarcinoma was more frequent in women, and squamous cell carcinoma was more frequent in men. The overall two- year survival rates for nonsmall cell, small cell and other lung cancers were 24%, 10% and 13%, respectively. In multivariate analysis, stage, thoracic surgery and chemotherapy were significantly associated with survival to two years in nonsmall cell carcinoma; only stage and chemotherapy were significant in small cell carcinoma.CONCLUSIONS: This study provides a Canadian epidemiological perspective, which generally concurs with the North American literature. Continued monitoring of the epidemiology of lung cancer is essential to evaluate the impact of advances in the diagnosis, staging and management of lung cancer. Further clinical and economic analysis, based on data collected on this cohort, is planned.

Introduction. Lung cancer is one of the most common malignant neoplasms, as well as the most common cause of death cancer. Most lung cancers are squamous cell carcinomas, small cell carcinomas or adenocarcinomas. Objective. Examining changes in trends of lung cancer incidence in Montenegro by histological type during a 15-year period, from 1997 to 2011. Methods. During the study period, histopathological confirmation was obtained for all primary lung cancer cases in the only hospital for lung diseases in the country. Based on the data from medical records, patients were classified by time period, sex, age groups and smoking history. Descriptive method was used. Results. Ratio between incidences of adenocarcinoma and squamous cell carcinoma changes in males, with a significant increase in the incidence rate of adenocarcinoma and drop in the rate of squamous cell carcinoma (p<0.001). In addition, statistically significant (p<0.05) decrease in the incidence of NSCLC (non-small cell lung cancer) and an increase in the incidence of SCLC (small cell lung cancer) was found. A statistically significant increase in linear trend in the incidence of small cell carcinoma was noted in females (p<0.005). Conclusion. Incidence rates of adenocarcinoma and small cell carcinoma have increased during the study period.

<p><strong>Background.</strong> Cigarette smoking is variably associated with the various histological cell types of lung cancer. The primary aim of this study was to analyse various strengths of association between the common histological cell types of lung cancer and smoking in a Western Cape population. The secondary aim examined whether an association exists between scar carcinoma and smoking.</p><p><strong>Methods</strong>. We retrospectively analysed the records from 386 patients over a 2-year period. Both smokers and non-smokers were subdivided and analysed as two groups, which included those with non-small cell and small cell lung cancer. Smokers and non-smokers were also analysed separately according to the presence or absence of lung scarring.</p><p><strong>Results.</strong> In total, 94.3% of all patients with lung cancer were current or past smokers. There was a disproportionately higher number of patients with adenocarcinoma who were non-smokers compared with all the other cell types (<strong>p</strong>=0.01), whereas patients with squamous cell carcinoma were more likely to be smokers (<strong>p</strong>=0.05). Although the vast majority of patients with and without lung scars were found to be smokers (96.4% v. 93.7% respectively), there was no statistically significant difference found between these two groups (<strong>p</strong>=0.43).</p><p><strong>Conclusion</strong>. In a Western Cape population, patients with adenocarcinoma were more likely to be non-smokers, while those with squamous cell carcinoma were relatively more likely to be smokers. No clear association between scar carcinoma and smoking status was found.</p>

BACKGROUND: Histological subtypes of lung cancer are crucial for making treatment decisions. However, multi-subtype classifications including adenocarcinoma (AC), squamous cell carcinoma (SqCC) and small cell carcinoma (SCLC) were rare in the previous studies. This study aimed at identifying and screening potential serum biomarkers for the simultaneous classification of AC, SqCC and SCLC. PATIENTS AND METHODS: A total of 143 serum samples of AC, SqCC and SCLC were analyzed by 1HNMR and UPLC-MS/MS. The stepwise discriminant analysis (DA) and multilayer perceptronMLPwere employed to screen the most efficient combinations of markers for classification. RESULTS: The results of non-targeted metabolomics analysis showed that the changes of metabolites of choline, lipid or amino acid might contribute to the classification of lung cancer subtypes. 17 metabolites in those pathways were further quantified by UPLC-MS/MS. DA screened out that serum xanthine, S-Adenosyl methionine (SAM), carcinoembryonic antigen (CEA), neuron-specific enolase (NSE) and squamous cell carcinoma antigen (SCC) contributed significantly to the classification of AC, SqCC and SCLC. The average accuracy of 92.3% and the area under the receiver operating characteristic curve of 0.97 would be achieved by MLP model when a combination of those five variables as input parameters. CONCLUSION: Our findings suggested that metabolomics was helpful in screening potential serum markers for lung cancer classification. The MLP model established can be used for the simultaneous diagnosis of AC, SqCC and SCLC with high accuracy, which is worthy of further study.

Few reports have described surgical resection for second primary lung cancers originating close to the initial surgical margin for lung cancer. A 64-year-old man had undergone left segmentectomy with lymph node dissection for small peripheral squamous cell lung cancer using video-assisted thoracic surgery, with pathology confirming a small tumor 12 mm in diameter identified about 3 cm from the surgical margin. Eighteen months after initial surgery, computed tomography revealed a 30 mm pulmonary nodule close to the initial surgical margin in the residual left upper lobe and the serum level of carcinoembryonic antigen was found to be increased. Local recurrence on the staple-line of the surgical margin was suspected, and completion left upper lobectomy was performed. Histological examination identified not only a squamous cell carcinoma component but also a small cell carcinoma component. The immunohistochemical staining pattern of the second tumor differed from that of the initial resected lung squamous cell carcinoma. The final pathological diagnosis was a second primary tumor with mixed small cell carcinoma and squamous cell carcinoma histology.

Background and Aim. The relative frequency of histological subtypes of lung cancer in Europe has changed dramatically during the 20th century. The aim of this study was to explore the changing epidemiology of lung cancer in Northern Greece over the last two decades. Methods. From the extensive database of the Bronchoscopy Unit of the G. Papanicolaou General Hospital, Thessaloniki, Greece, we identified all patients with a histologic and/or cytologic report positive for lung cancer over two consecutive decades. Results. Between 1/1/1986 and 31/12/2005 we identified 9981 patients with specimens positive for lung cancer. A significant increase in mean patient age was observed during the second decade (64.8±9.4 vs. 62.1±8.9, p=0.001). Men developed lung cancer ten times more often than women. The predominant histological type was squamous cell cancer in males (4203 cases, 45.7%) and adenocarcinoma (418 cases, 52.6%) in females. The number of lung cancer cases was significantly higher during the second decade compared to the first decade (5766 cases [57.8%] vs. 4215 cases [42.2%], respectively, p&lt;0.001). There was a significant decrease in the percentage of squamous cell carcinoma in males in the second decade (2317 cases [44.1%] vs. 1886 cases [48.0%], p&lt;0.001), and an increase in adenocarcinoma (1021 cases [19.4%] vs. 609 [11.6%], p&lt;0.001). In females, the relative incidence of adenocarcinoma was decreased and that of squamous cell carcinoma was increased, but not significantly. There was no obvious change in the incidence of small cell lung cancer. Neoplastic lesions were most often located in the upper lobes. Conclusion. The number of lung cancer cases has increased in the last decade. Squamous lung cancer appears to be decreasing in men and increasing in women. Adenocarcinoma appears to be increasing in men and decreasing in women. There appears to be no change in small cell lung cancer. During the second decade there has been a significant decrease in the male: female ratio.
