Lung cancer biomarkers for the assessment of modified risk tobacco products: an oxidative stress perspective.

Abstract
Abstract Manufacturers have developed prototype cigarettes yielding reduced levels of some tobacco smoke toxicants, when tested using laboratory machine smoking under standardised conditions. For the scientific assessment of modified risk tobacco products, tests that offer objective, reproducible data, which can be obtained in a much shorter time than the requirements of conventional epidemiology are needed. In this review, we consider whether biomarkers of biological effect related to oxidative stress can be used in this role. Based on published data, urinary 8-oxo-7,8-dihydro-2-deoxyguanosine, thymidine glycol, F2-isoprostanes, serum dehydroascorbic acid to ascorbic acid ratio and carotenoid concentrations show promise, while 4-hydroxynonenal requires further qualification.

Advance lung cancer inflammation index (ALI) at diagnosis is a prognostic marker in patients with metastatic non-small cell lung cancer (NSCLC): a retrospective review.

BMC Cancer. 2013 Mar 27;13(1):158

Abstract
BACKGROUND: Systemic inflammation has been linked with cancer development, cancer cachexia and poor outcome. Advanced lung cancer inflammation index (ALI) was developed to assess degree of systemic inflammation at the time of diagnosis in metastatic non-small cell lung (NSCLC) cancer patients. METHODS: In a single institution retrospective review 173 patients with metastatic NSCLC diagnosed between Jan 1 2000 and June 30 2011 were included. ALI was calculated as (BMI x Alb / NLR) where BMI = body mass index, Alb = serum albumin, NLR (neutrophil lymphocyte ratio, a marker of systemic inflammation). Patients were divided into low inflammation (ALI >= 18) and high inflammation (ALI < 18) groups. Kaplan-Meier method was used to estimate progression free survival and overall survival. Log-rank test were used to compare the survivals among various factors. Multivariate Cox regression was used to perform survival analysis in order to estimate the hazards ratio for various factors. RESULTS: Among 173 patients median age was 57 years, 67% were male, 52% had adenocarcinoma. Patients with an ALI score of < 18 suggesting high systemic inflammation were significantly more likely to have more than 2 sites of metastatic disease, have poor performance status and less likely to receive any chemotherapy. Their median progression free survival and overall survival was 2.4 months and 3.4 months as opposed to 5.1 months and 8.3 months in patients with ALI >18 (P < 0.001). On multi-variate analysis ALI score of <18(1.42, 95% CI 1.003-2.01) remained significantly associated with worse outcome. CONCLUSION: ALI (<18) at diagnosis is an independent marker of poor outcome in patients with advanced NSCLC.

Tuberculosis comorbidity with communicable and non-communicable diseases: integrating health services and control efforts.

Abstract
Recent data for the global burden of disease reflect major demographic and lifestyle changes, leading to a rise in non-communicable diseases. Most countries with high levels of tuberculosis face a large comorbidity burden from both non-communicable and communicable diseases. Traditional disease-specific approaches typically fail to recognise common features and potential synergies in integration of care, management, and control of non-communicable and communicable diseases. In resource-limited countries, the need to tackle a broader range of overlapping comorbid diseases is growing. Tuberculosis and HIV/AIDS persist as global emergencies. The lethal interaction between tuberculosis and HIV coinfection in adults, children, and pregnant women in sub-Saharan Africa exemplifies the need for well integrated approaches to disease management and control. Furthermore, links between diabetes mellitus, smoking, alcoholism, chronic lung diseases, cancer, immunosuppressive treatment, malnutrition, and tuberculosis are well recognised. Here, we focus on interactions, synergies, and challenges of integration of tuberculosis care with management strategies for non-communicable and communicable diseases without eroding the functionality of existing national programmes for tuberculosis. The need for sustained and increased funding for these initiatives is greater than ever and requires increased political and funder commitment.

Prognostic Value of the New International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society Lung Adenocarcinoma Classification on Death and Recurrence in Completely Resected Stage I Lung Adenocarcinoma.

Abstract
OBJECTIVE:: This study investigated the prognostic value of the new International Association for the Study of Lung Cancer, American Thoracic Society, and European Respiratory Society (IASLC/ATS/ERS) lung adenocarcinoma classification in resected stage I lung adenocarcinoma. METHODS:: Histological classification of 283 patients undergoing surgical resection for stage I lung adenocarcinoma was determined according to the IASLC/ATS/ERS classification after comprehensive histological subtyping with recording of the percentage of each histological component (lepidic, acinar, papillary, micropapillary, and solid) in 5% increments. Their impact on overall survival, recurrence, and postrecurrence survival was investigated. RESULTS:: The 5-year overall survival and recurrence-free rates were 81.6% and 76.9%, respectively. During follow-up, 57 (20.1%) patients developed recurrence. The 2-year postrecurrence survival rate was 72.3%. The solid predominant group is associated with significant more male sex, higher smoking exposure, larger tumor size, and more poorly differentiated histological grade. Lepidic predominant group had significantly better overall survival (P = 0.002). Micropapillary and solid predominant groups had significantly lower probability of freedom from recurrence (P = 0.004). Older age (P = 0.039), visceral pleural invasion to the surface (PL2) (P = 0.009), and high grade (micropapillary/solid predominant) of the new classification (P = 0.028) were predictors of recurrence in multivariate analysis. The solid predominant group tends to have significantly worse postrecurrence survival (P = 0.074). CONCLUSIONS:: The new adenocarcinoma classification has significant impact on death and recurrence in stage I lung adenocarcinoma. Patients with PL2 and micropapillary/solid predominant pattern have significant higher risk for recurrence. This information is important for patient stratification for aggressive adjuvant chemoradiation therapy.

Efficacy of bevacizumab-containing chemotherapy for non-squamous non-small cell lung cancer with bone metastases.

Abstract
PURPOSE: Skeletal-related events (SREs) negatively affect the quality of life of patients with cancer. Vascular endothelial growth factor receptor (VEGFR)-targeted therapy is effective against bone metastasis in animal models, but the clinical efficacy of anti-VEGFR inhibitors against bone metastases remains unclear. Therefore, we aimed to investigate the efficacy of chemotherapy with bevacizumab, an anti-VEGF antibody, against bone metastases. METHODS: We retrospectively reviewed consecutive patients with non-squamous non-small cell lung cancer who received first-line platinum-based chemotherapy with zoledronic acid at Shizuoka Cancer Center between 2007 and 2011. RESULTS: Of 25 patients, 13 received bevacizumab-based chemotherapy (BEV group) and 12 received chemotherapy without bevacizumab (non-BEV group). The overall response (54 vs. 8 %, p = 0.01) and disease control (100 vs. 50 %, p = 0.01) rates were higher in the BEV group than in the non-BEV group. The bone-specific response (23 vs. 0 %, p = 0.038) and disease control (100 vs. 67 %, p = 0.01) rates were also higher in the BEV group. The median time to progression (TTP) for bone metastases was higher in the BEV group (13.7 vs. 4.3 months, p = 0.06), whereas that for overall disease was similar between the groups (5.7 vs. 2.6 months, p = 0.17). The proportions of patients with SREs were 23 and 50 % in the BEV and non-BEV groups, respectively (p = 0.16). CONCLUSION: Bevacizumab might potentiate the antitumor activity of chemotherapy against systemic disease and bone metastases, prolonging bone-specific TTP and reducing the incidence of SRE.
