Abstract
Patients of African ancestry have the poorest outcome and the shortest survival rates from cancer globally. This could be attributed to many variables including racial, biological, socioeconomic and sociocultural factors (either single, multiple or combined), which may be responsible for this major health problem. We sought to assess the most common types of cancer that endanger the health of the African people, and tried to investigate the real differences between African and other Non-African patients regarding incidence, prevalence and mortality rates of different cancers. Therefore, identifying the underlying aetiological causes responsible for the increased incidence and mortality rates of African patients will allow for changing the current plans, to make optimized modalities for proper screening, diagnosis and treatment for those African patients, in order to improve their survival and outcomes.

Abstract
The management of stage III non-small cell lung cancer (NSCLC) remains complex and controversial, with a myriad of potentially feasible options. Given the diversity of non-surgical as well as surgical options, along with recent randomized data regarding adjuvant immunotherapy that has re-defined the standard of care for unresected stage III NSCLC cases, the goal of this narrative review was to provide a contemporary view at how management of these patients can be further optimized. Topics discussed include the following items: optimizing toxicity mitigation strategies (in order to avoid impaired receipt of subsequent therapies), the importance of multidisciplinary tumor boards (MTBs) and multidisciplinary clinics (MDCs), adhering to treatment approaches endorsed by national guidelines, prudently selecting patients for surgical intervention (as compared to non-operative approaches), coordination of multidisciplinary care so as to best preserve all potential therapeutic options, and addressing challenges regarding disparities in access to oncologic care. This review places particular emphasis for community and/or rural centers, which may not have the same level of resources and/or personnel as larger academic institutions. Taken together, these strategies are aimed towards the overarching goal of streamlining oncologic care for stage III NSCLC cases in light of the numerous approaches that currently exist for these patients.

Abstract
PURPOSE African Americans, especially men, have a higher incidence of lung cancer compared with all other racial and ethnic groups in the US. Self-reported race is frequently used in genomic research studies to capture an individual's race or ethnicity. However, it is clear from studies of genetic admixture that human genetic variation does not segregate into the same biologically discrete categories as socially defined categories of race. Previous studies have suggested that the degree of West African ancestry among African Americans can contribute to cancer risk in this population, though few studies have addressed this question in lung cancer. METHODS Using a genetic ancestry panel of 100 SNPs, we estimated West African, European, and Native American ancestry in 1,407 self-described African Americans and 2,413 European Americans. RESULTS We found that increasing West African ancestry was associated with increased risk of lung cancer among African American men (ORQ5 vs Q1 = 2.55 (1.45-4.48), p = 0.001), while no association was observed in African American women (ORQ5 vs Q1 = 0.90 (0.51-1.59), p = 0.56). This relationship diminished following adjustment for income and education. CONCLUSIONS Genetic ancestry is not a major contributor to lung cancer risk or survival disparities.

Abstract
Many factors contribute to the poor survival of malignant brain tumor patients, some of which are not easily remedied. However, one contributor to the lack of progress that may be modifiable is poor clinical trial accrual. Surveys of brain tumor patients and neuro-oncology providers suggest that clinicians do a poor job of discussing clinical trials with patients and referring patients for clinical trials. Yet, data from the Cancer Action Network of the American Cancer Society suggest that most eligible oncology patients asked to enroll on a clinical trial will agree to do so. To this end, the Society for Neuro-Oncology (SNO) in collaboration with the Response Assessment in Neuro-Oncology (RANO) Working Group, patient advocacy groups, clinical trial cooperative groups, including the Adult Brain Tumor Consortium (ABTC), and other partners are working together with the intent to double clinical trial accrual over the next 5 years. Here we describe the factors contributing to poor clinical trial accrual in neuro-oncology and offer possible solutions.

Abstract
Background This study investigates the characteristics of a special type of cancer of unknown primary site (CUP, type 2), which is a metastasis of a definite pathological diagnosis without a detectable primary site. Patients and methods Patients diagnosed between 2004 and 2014 were identified from the Surveillance Epidemiology and End Results (SEER) database. The characteristics of type 2 CUP from different sources were analyzed. For each source of type 2 CUP, tumors of the corresponding TnN0‐XM1 stage were used as controls. Results A total of 8505 patients with type 2 CUP were included in this analysis. Type 2 CUP shows an increasing trend, while type 1 shows the opposite. Type 2 CUPs have significant differences with stage IV of the same pathological primary lesion. Many characteristics influenced the prognosis of type 2 CUP patients, including marital status, age, race, sex, registration time, lymph node metastasis, surgery, chemotherapy, and radiation. Conclusion Our study suggests that identifying the source of metastasis is the key to the selection of treatment and the determination of the prognosis for CUP.

Abstract
Compared with all other racial and ethnic groups in the United States, African Americans are disproportionally affected by lung cancer, both in terms of incidence and survival. It is likely that smoking, as the main etiological factor associated with lung cancer, contributes to these disparities, but the precise mechanism is still unclear. This paper seeks to explore the history of lung cancer disparities and review to the literature regarding the various factors that contribute to them.

Abstract
OBJECTIVES To examine the role of uniform access to care in reducing racial/ethnic disparities in receipt of resection for early stage non-small cell lung cancer (NSCLC) by comparing integrated health system member patients to demographically similar non-member patients. MATERIALS AND METHODS Using data from the California Cancer Registry, we conducted a retrospective cohort study of patients from four racial/ethnic groups (White, Black, Hispanic, Asian/Pacific Islander), aged 21-80, with a first primary diagnosis of stage I or II NSCLC between 2004 and 2011, in counties served by Kaiser Permanente Northern California (KPNC) at diagnosis. Our cohort included 1565 KPNC member and 4221 non-member patients. To examine the relationship between race/ethnicity and receipt of surgery stratified by KPNC membership, we used modified Poisson regression to calculate risk ratios (RR) adjusted for patient demographic and tumor characteristics. RESULTS Black patients were least likely to receive surgery regardless of access to integrated care (64-65% in both groups). The magnitude of the black-white difference in the likelihood of surgery receipt was similar for members (RR: 0.82, 95% CI: 0.73-0.93) and non-members (RR: 0.86, 95% CI: 0.80-0.94). Among members, roughly equal proportions of Hispanic and White patients received surgery; however, among non-members, Hispanic patients were less likely to receive surgery (non-members, RR: 0.93, 95% CI: 0.86-1.00; members, RR: 0.98, 95% CI: 0.89-1.08). CONCLUSION Disparities in surgical treatment for NSCLC were not reduced through integrated health system membership, suggesting that factors other than access to care (e.g., patient-provider communication) may underlie disparities. Future research should focus on identifying such modifiable factors.

Abstract
BACKGROUND African Americans (AA) experience higher incidence and mortality of lung cancer as compared with European Americans (EA). Inflammation is associated with lung cancer, many aspects of which differ between AA and EA. We investigated whether use, frequency, and duration of the anti-inflammatory drug aspirin were associated with lung cancer risk and survival, separately among AA and EA populations. METHODS Using data from the Maryland Non-Small Cell Lung Cancer (NSCLC) Case-Control Study (1,220 cases [404 AA and 816 EA] and 1,634 controls [1,004 EA and 630 AA]), we estimated the adjusted odds ratios (OR) and hazard ratios (HR) with 95% confidence intervals (CI) of the associations between aspirin use and NSCLC risk and survival, respectively. RESULTS Any aspirin use (OR: 0.66; 95% CI, 0.49-0.89), daily use of ≥ 1 tablet (OR: 0.68; 95% CI, 0.50-0.90), and use for ≥ 3 years (OR: 0.61; 95% CI, 0.44-0.85) was associated with lower NSCLC risk only among men, even after adjustment for covariates including body mass index and global genetic ancestry. These variables were also associated with improved survival, but only among AA (HR: 0.64; 95% CI, 0.46-0.91; HR: 0.61; 95% CI, 0.42-0.90; and HR: 0.60; 95% CI, 0.39-0.92, respectively). Tylenol and other NSAIDs were either associated with elevated or no NSCLC risk. CONCLUSIONS Aspirin use is associated with lower risk of NSCLC among men and improved survival among AA. IMPACT Preventive regular aspirin use could be considered among men and AA.

Abstract
PURPOSE Lung cancer is a multifactorial malignancy for which some risk factors, such as chronic lung diseases, their interactions with smoking, and how they differ by race and sex, are not fully understood. We investigated the associations between chronic inflammatory lung disease and non-small cell lung carcinoma (NSCLC) and how sex and race may affect such associations. METHODS Using logistic regression, we analyzed 1660 lung cancer cases and 1959 population controls and estimated adjusted odds ratios (AORs) and 95% confidence intervals (CIs). RESULTS Chronic lung disease was significantly associated with higher odds of having NSCLC in never (AOR = 1.99; 95% CI = 1.19-3.34), former (AOR = 1.68; 95% CI = 1.29-2.20), and current smokers (AOR = 2.40; 95% CI = 1.62-3.57), after adjustment for relevant covariates. For each 5-year increment in chronic lung disease duration, the risk of lung cancer increased only among females (AOR = 1.07; 95% CI = 1.02-1.13). Females, but not males, with asthma were at risk for NSCLC (AOR = 2.08; 95% CI = 1.40-3.10). CONCLUSIONS This study provides support for chronic lung inflammation as a potential contributing factor to lung cancer risk and possible sex difference in the inflammatory events underlying disease mechanisms.

Cancer 2017; 123 Suppl 24:5079-5099.

Abstract
BACKGROUND Results from the second CONCORD study (CONCORD-2) indicated that 5-year net survival for lung cancer was low (range, 10%-20%) between 1995 and 2009 in most countries, including the United States, which was at the higher end of this range. METHODS Data from CONCORD-2 were used to analyze net survival among patients with lung cancer (aged 15-99 years) who were diagnosed in 37 states covering 80% of the US population. Survival was corrected for background mortality using state-specific and race-specific life tables and age-standardized using International Cancer Survival Standard weights. Net survival was estimated for patients diagnosed between 2001 and 2003 and between 2004 and 2009 at 1, 3, and 5 years after diagnosis by race (all races, black, and white); Surveillance, Epidemiology, and End Results Summary Stage 2000; and US state. RESULTS Five-year net survival increased from 16.4% (95% confidence interval, 16.3%-16.5%) for patients diagnosed 2001-2003 to 19.0% (18.8%-19.1%) for those diagnosed 2004-2009, with increases in most states and among both blacks and whites. Between 2004 and 2009, 5-year survival was lower among blacks (14.9%) than among whites (19.4%) and ranged by state from 14.5% to 25.2%. CONCLUSIONS Lung cancer survival improved slightly between the periods 2001-2003 and 2004-2009 but was still low, with variation between states, and persistently lower survival among blacks than whites. Efforts to control well established risk factors would be expected to have the greatest impact on reducing the burden of lung cancer, and efforts to ensure that all patients receive timely and appropriate treatment should reduce the differences in survival by race and state.
