Abstract
OBJECTIVES To investigate the role of comorbid chronic obstructive pulmonary disease (COPD) and symptom type on general practitioners' (GP's) symptom attribution and clinical decision-making in relation to lung cancer diagnosis. DESIGN Vignette survey with a 2×2 mixed factorial design. SETTING A nationwide online survey exploring clinical decision-making in primary care. PARTICIPANTS 109 GPs based in the United Kingdom (UK) who were registered as responders on Dynata (an online survey platform). INTERVENTIONS GPs were presented with four vignettes which described a patient aged 75 with a smoking history presenting with worsening symptoms (either general or respiratory) and with or without a pre-existing diagnosis of COPD. PRIMARY AND SECONDARY OUTCOME MEASURES GPs indicated the three most likely diagnoses (free-text) and selected four management approaches (20 pre-coded options). Attribution of symptoms to lung cancer and referral for urgent chest X-ray were primary outcomes. Alternative diagnoses and management approaches were explored as secondary outcomes. Multivariable mixed-effects logistic regression was used, including random intercepts for individual GPs. RESULTS 422 vignettes were completed. There was no evidence for COPD status as a predictor of lung cancer attribution (OR=1.1, 95% CI=0.5-2.4, p=0.914). There was no evidence for COPD status as a predictor of urgent chest X-ray referral (OR=0.6, 95% CI=0.3-1.2, p=0.12) or as a predictor when in combination with symptom type (OR=0.9, 95% CI=0.5-1.8, p=0.767). CONCLUSIONS Lung cancer was identified as a possible diagnosis for persistent respiratory by only one out of five GPs, irrespective of the patients' COPD status. Increasing awareness among GPs of the link between COPD and lung cancer may increase the propensity for performing chest X-rays and referral for diagnostic testing for symptomatic patients.

Abstract
OBJECTIVES Lung cancer continues to be the most common cause of cancer-related death and the leading cause of morbidity and burden of disease across Australia. There is an ongoing need to identify and reduce unwarranted clinical variation that may contribute to these poor outcomes for patients with lung cancer. An Australian national strategy acknowledges clinical quality outcome data as a critical component of a continuously improving healthcare system but there is a need to ensure clinical quality indicators adequately measure evidence-based contemporary care, including novel and emerging treatments. This study aimed to develop a suite of lung cancer-specific, evidence-based, clinically acceptable quality indicators to measure quality of care and outcomes, and an associated comparative feedback dashboard to provide performance data to clinicians and hospital administrators. DESIGN A multistage modified Delphi process was undertaken with a Clinical Advisory Group of multidisciplinary lung cancer specialists, with patient representation, to update and prioritise potential indicators of lung cancer care derived from a targeted review of published literature and reports from national and international lung cancer quality registries. Quality indicators were piloted and evaluated with multidisciplinary teams in a retrospective observational cohort study using clinical audit data from the Embedding Research (and Evidence) in Cancer Healthcare Program, a prospective clinical cohort of over 2000 patients with lung cancer diagnosed from May 2016 to October 2021. SETTING AND PARTICIPANTS Six tertiary specialist cancer centres in metropolitan and regional New South Wales, Australia. RESULTS From an initial 37 potential quality indicators, a final set of 10 indicators spanning diagnostic, treatment, quality of life and survival domains was agreed. CONCLUSIONS These indicators build on and update previously available measures of lung cancer care and outcomes in use by national and international lung cancer clinical quality registries which, to our knowledge, have not been recently updated to reflect the changing lung cancer treatment paradigm.

Abstract
PURPOSE This study investigates the association between socioeconomic position (SEP) and health-related quality of life (HRQoL) in a cross-sectional cohort among cancer survivors and compares with cancer-free people. METHODS Survivors of colorectal, hematological, gynecological, prostate, thyroid cancer, and melanoma diagnosed 2000-2014 were identified in the PROFILES registry, and an age- and sex-matched cancer-free population were identified in the CentER panel. HRQoL, education, and comorbidity were self-reported. Street-level income and clinical factors were obtained from Statistics Netherlands and the Netherlands Cancer Registry. Multivariable logistic regression was used to examine associations of SEP (measured by education and income) and impaired HRQoL among cancer survivors and the cancer-free population, adjusting for age, sex, and time since diagnosis. RESULTS We included 6693 cancer survivors and 565 cancer-free people. Cancer survivors with low versus medium SEP more frequently reported impaired HRQoL (odds ratio (OR) range for all HRQoL outcomes, 1.06-1.78 for short education and 0.94-1.56 for low income). Survivors with high compared to medium SEP reported impaired HRQoL less frequently (OR range for all HRQoL outcomes, 0.46-0.81 for short education and 0.60-0.84 for low income). The association between SEP and HRQoL was similar in the matched cancer-free population. CONCLUSION Low SEP was associated with impaired HRQoL in both cancer survivors and cancer-free people. IMPLICATIONS FOR CANCER SURVIVORS Targeted care is warranted for cancer survivors with impaired HRQoL, especially among those with low SEP.

Abstract
BACKGROUND The socioeconomic differences in survival are pronounced for patients diagnosed with head and neck cancer; disease stage at diagnosis is suggested to be a main driver of this association. This nationwide, population-based study investigates socioeconomic differences in the pre-diagnostic interval and disease stage at diagnosis. MATERIAL AND METHODS Information on patient-reported symptoms, symptom onset and disease-specific factors was obtained from the nationwide population-based Danish Head and Neck Cancer Group (DAHANCA) database for patients diagnosed with head and neck squamous cell carcinoma between 2008 and 2019 in Denmark. Socioeconomic position (SEP) was measured by individual-level education, income and cohabitation status obtained from administrative registers. Socioeconomic differences in the interval from symptom onset to diagnosis were investigated in general linear models with 95% confidence intervals (CIs); overall and by subsite, symptom and comorbidity score. Consultation patterns prior to diagnosis were examined using methods for change-point detection. Associations with advanced-stage disease were estimated in logistic regression models. RESULTS Patients with low, medium and high SEP had a similar interval from patient-reported symptom onset to diagnosis of 10 weeks. Although this interval varied according to primary symptom and anatomical subsite, no apparent socioeconomic differences were observed within these subgroups. Aligned with the patient-reported symptom onset, a distinct increase in consultation rates was observed at 9 weeks (95% CI [7.3; 10.7]) for patients with low SEP and 7 weeks (95% CI [4.8; 9.2]) for patients with high SEP, with overlapping CIs. Patients with low compared to high SEP had increased odds for advanced-stage glottic and oral cavity squamous cell carcinoma. For the remaining subsites the association varied according to SEP-indicator and TNM-edition. CONCLUSION The interval from symptom onset to diagnosis and consultation patterns were similar across SEP groups. Still, socioeconomic differences in stage at diagnosis were observed for some - but not all - subsites.

Abstract
Delays in the assessment, management, and treatment of lung cancer patients may adversely impact prognosis and survival. This study is the first to use machine learning techniques to predict the quality and timeliness of care among lung cancer patients, utilising data from the Victorian Lung Cancer Registry (VLCR) between 2011 and 2022, in Victoria, Australia. Predictor variables included demographic, clinical, hospital, and geographical socio-economic indices. Machine learning methods such as random forests, k-nearest neighbour, neural networks, and support vector machines were implemented and evaluated using 20% out-of-sample cross validations via the area under the curve (AUC). Optimal model parameters were selected based on 10-fold cross validation. There were 11,602 patients included in the analysis. Evaluated quality indicators included, primarily, overall proportion achieving "time from referral date to diagnosis date ≤ 28 days" and proportion achieving "time from diagnosis date to first treatment date (any intent) ≤ 14 days". Results showed that the support vector machine learning methods performed well, followed by nearest neighbour, based on out-of-sample AUCs of 0.89 (in-sample = 0.99) and 0.85 (in-sample = 0.99) for the first indicator, respectively. These models can be implemented in the registry databases to help healthcare workers identify patients who may not meet these indicators prospectively and enable timely interventions.

Abstract
BACKGROUND We examined the number of lung cancers diagnosed, the quality of care and the socio-economic and clinical characteristics among patients with lung cancer during the COVID-19 pandemic compared to previous years. METHODS We included all patients ≥ 18 years old diagnosed with lung cancer from 01 January 2018 to 31 August 2021 as registered in the Danish Lung Cancer Registry. Using a generalised linear model, we estimated prevalence ratios (PR) and 95% confidence intervals (CI) of the associations between the pandemic and socioeconomic and clinical factors, and indicators of quality. RESULTS We included 18,113 patients with lung cancer (82.0% non-small cell lung cancer (NSCLC)), which was similar to the preceding years, although a decline in NSCLC cases occurred during the first lockdown period in 2020. No difference in distribution of income or educational level was observed. No difference was observed in the quality of treatment - as measured by curative intent, proportion of patients resected or who died within 90 days of diagnosis. CONCLUSION Using nationwide population-based data, our study reassuringly shows no adverse effects of the COVID-19 pandemic on the diagnosis, socio-economic characteristics nor quality of treatment of lung cancer, as compared to the preceding years.

Abstract
Objective The Hungarian Undiagnosed Lung Cancer (HULC) study aimed to explore the potential reasons for missed LC (lung cancer) diagnosis by comparing healthcare and socio-economic data among patients with post-mortem diagnosed LC with those who were diagnosed with LC during their lives. Methods This nationwide, retrospective study used the databases of the Hungarian Central Statistical Office (HCSO) and National Health Insurance Fund (NHIF) to identify patients who died between January 1, 2019 and December 31, 2019 and were diagnosed with lung cancer post-mortem (population A) or during their lifetime (population B). Patient characteristics, socio-economic factors, and healthcare resource utilization (HCRU) data were compared between the diagnosed and undiagnosed patient population. Results During the study period, 8,435 patients were identified from the HCSO database with LC as the cause of death, of whom 1,203 (14.24%) had no LC-related ICD (International Classification of Diseases) code records in the NHIF database during their lives (post-mortem diagnosed LC population). Post-mortem diagnosed LC patients were significantly older than patients diagnosed while still alive (mean age 71.20 vs. 68.69 years, p<0.001), with a more pronounced age difference among female patients (difference: 4.57 years, p<0.001), and had significantly fewer GP (General Practitioner) and specialist visits, X-ray and CT scans within 7 to 24 months and 6 months before death, although the differences in GP and specialist visits within 7-24 months did not seem clinically relevant. Patients diagnosed with LC while still alive were more likely to be married (47.62% vs. 33.49%), had higher educational attainment, and had more children, than patients diagnosed with LC post-mortem. Conclusions Post-mortem diagnosed lung cancer accounts for 14.24% of total lung cancer mortality in Hungary. This study provides valuable insights into patient characteristics, socio-economic factors, and HCRU data potentially associated with a high risk of lung cancer misdiagnosis.

Abstract
Background: GPC5 rs2352028 is associated with the risk of lung cancer, but its relationship with lung cancer prognosis is unclear. Materials & methods: The authors collected blood samples from 888 patients with lung cancer and used a Cox proportional hazards model to analyze the association between prognosis and GPC5 polymorphism rs2352028. Results: GPC5 rs2352028 C > T was associated with a better prognosis. Patients with CT genotype had longer overall survival than those with CC genotype. Additionally, older and early-stage patients with CT + TT genotype had a lower risk of death than those with CC genotype. Conclusion: GPC5 rs2352028 C > T may play a protective role in patients with lung cancer and GPC5 rs2352028 may be a potential genetic marker for lung cancer prognosis.

Abstract
The aim was to verify the association of individual factors and healthcare system characteristics with time to initiate treatment of lung cancer by the Brazilian National Health System, in Minas Gerais state. A retrospective cohort study, with patients who initiated treatment for lung cancer by the SUS, from 2008 to 2015. Sociodemographic and clinical characteristics of patients, besides organizational variables of the healthcare system were selected. The logistic regression model evaluated the association of selected explanatory variables with the outcome of initiating treatment within 60 days after diagnosis. Odds ratio (OR) and respective 95% confidence interval were used to measure the power of association. Most treatments for lung cancer in the state of Minas Gerais initiated within 60 days after diagnosis. However, being male and diagnosed as stage IV increased the likelihood of starting treatment within 60 days. On the other hand, the patient's age, radiation therapy as first treatment, and the place of residence decreased such chance. Time to initiate treatment is associated with individual characteristics and provision of services in macroregions, and the observed inequalities possibly raised from the better or worse access of the population to the services provided by SUS.

Palliat Care Soc Pract 2022; 16:26323524221097982. [PMID: 35800415 PMCID: PMC9253993 DOI: 10.1177/26323524221097982] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Accepted: 04/14/2022] [Indexed: 11/28/2022] Open
Abstract
Background: Despite a tax-funded, needs-based organisation of the Danish health system,
social inequality in cancer rehabilitation and palliative care (PC) has been
noted repeatedly. Little is known about how best to improve access and
participation in cancer rehabilitation and PC for socio-economically
disadvantaged and socially vulnerable patients. Aim: To gather, synthesise and describe practice-orientated development studies
presented in Danish-language publications and examine the underpinning
conceptualisations of social inequality and vulnerability; explore related
views of stakeholders working in the field. Methods: The study comprised a narrative review of Danish-language literature on
practice-orientated development studies which address social inequality and
vulnerability in cancer rehabilitation and PC and an online stakeholder
consultation workshop with Danish professionals and academics working in the
field. Results: Two themes characterise the included publications (n = 8):
types of interventions; conceptualisations of social inequality and
vulnerability; three themes were identified in the workshop data: focus and
type of interventions; organisation of cancer care; and vulnerability of the
healthcare system. The publications and the workshop participants
(n = 12) favoured approaches which provide additional
individualised resources throughout the cancer trajectory for this patient
group. The terms social inequality and social vulnerability are largely used
interchangeably, and associated with low income and no or little education
yet qualified with multiple descriptors, which reflect the diverse
socio-economic situations professionals encounter in cancer patients and
their psychosocial needs. Conclusion: Addressing social inequality and vulnerability in cancer rehabilitation and
PC in Denmark entails practical and conceptual challenges. Of importance is
individualised support and the integration of rehabilitation and PC into
standardised care pathways. To conceive of social vulnerability as a
layered, dynamic, relational and contextual concept reflects current
practice in identifying the diversity of cancer patients who may benefit
from additional support in accessing and participating in rehabilitation and
PC.

Abstract
Objective: This study aimed to examine the characteristics of the lung cancer (LC) patient pathway in Hungary during a 6-years period. Methods: This nationwide, retrospective study included patients newly diagnosed with LC (ICD-10 C34) between January 1, 2011, and December 31, 2016, using data from the National Health Insurance Fund (NHIF) of Hungary. The following patient pathway intervals were examined: system, diagnostic and treatment interval by age, gender, tumor type, study year and first-line LC therapy. Results: During the 6-years study period, 17,386 patients had at least one type of imaging (X-ray or CT/MRI) prior to diagnosis, and 12,063 had records of both X-ray and CT/MRI. The median system interval was 64.5 days, and it was 5 days longer among women, than in men (68.0 vs. 63.0 days). The median system interval was significantly longer in patients with adenocarcinoma compared to those with squamous cell carcinoma or small cell lung cancer (70.4 vs. 64.0 vs. 48.0 days, respectively). Patients who received surgery as first-line treatment had significantly longer median system intervals compared to those receiving chemotherapy (81.4 vs. 62.0 days). The median system interval significantly increased from 62.0 to 66.0 days during the 6-years study period. Conclusion: The LC patient pathway significantly increased in Hungary over the 6-years study period. There were no significant differences in the length of the whole LC patient pathway according to age, however, female sex, surgery as first-line treatment, and adenocarcinoma were associated with longer system intervals.

Associations Between CAMKK1 Polymorphism rs7214723 and the Prognosis of Patients With Lung Cancer. Front Oncol 2021; 11:757484. [PMID: 34868969 PMCID: PMC8640188 DOI: 10.3389/fonc.2021.757484] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Accepted: 10/26/2021] [Indexed: 11/18/2022] Open
Abstract
Background The 5-year survival rate of patients with lung cancer in China is less than 20% and predicting their prognosis is challenging. We investigated the association between a common non-synonymous single nucleotide polymorphism (SNP), rs7214723, in the Ca2+/calmodulin-dependent protein kinase kinase 1 (CAMKK1) gene and the prognosis of patients with lung cancer. Methods Genomic DNA was extracted from the blood samples of 839 patients with lung cancer, recruited from Changhai Hospital (n = 536) and Taizhou Institute of Health Sciences (n = 352), and genotyped using the SNPscan technique. The association between patient prognosis and the genotypic data for CAMKK1 was analyzed using a multivariate Cox proportional hazards model adjusted for multiple potential confounders. The CRISPR/Cas9 gene-editing system was used to introduce point mutations in the CAMKK1 rs7214723 of A549 and NCI-H358 cells. Subsequently, Cell proliferation and migration ability were assessed with the Cell Counting Kit-8 and scratch assay. The Annexin V-FITC apoptosis detection kit was used to detect cell apoptosis. Results The CAMKK1 rs7214723 recessive CC genotype conferred significantly better overall survival (CC vs. TT + TC: adjusted hazard ratio = 0.78, 95% confidence interval [CI], 0.61-1.00, P = 0.049) than the TT + TC genotypes. Stratified analysis showed that the CAMKK1 rs7214723 CC genotype and recessive CC genotype conferred a significantly decreased risk of death in patients who were male, had a smoking history, or had stage III + IV cancer, compared with the TT and TT + TC genotypes. Relative to the TT + TC genotypes, the rs7214723 recessive CC genotype was also associated with a decreased risk of death in patients aged < 60 years (CC vs. TT + TC: adjusted hazard ratio = 0.59, 95% CI, 0.37-0.93, P = 0.024) and patients with squamous cell carcinoma (CC vs. TT + TC: adjusted hazard ratio = 0.65, 95% CI, 0.44-0.98, P = 0.038). Remarkably, CRISPR/Cas9-guided single nucleotide editing demonstrated that CAMKK1 rs7214723 T > C mutation significantly inhibits cell proliferation and migration and promotes cell apoptosis. Conclusions CAMKK1 SNP rs7214723 may be a significant prognostic factor for the risk of death among patients with lung cancer.

Associations between comorbidities and advanced stage diagnosis of lung, breast, colorectal, and prostate cancer: A systematic review and meta-analysis. Cancer Epidemiol 2021; 75:102054.

Abstract
Comorbidities and advanced stage diagnosis (ASD) are both associated with poorer cancer outcomes, but the association between comorbidities and ASD is poorly understood. We summarized epidemiological evidence on the association between comorbidities and ASD of selected cancers in a systematic review and meta-analysis. We searched PubMed and Web of Science databases up to June 3rd, 2021 for studies assessing the association between comorbidities and ASD of lung, breast, colorectal, or prostate cancer. Summary odds ratios (ORs) and 95% confidence intervals (95%CIs) were calculated using random-effects models. Also, potential variations in the associations between comorbidities and ASD by cancer type were investigated using random-effects meta-regression. Thirty-seven studies were included in this review, including 8,069,397 lung, breast, colorectal, and prostate cancer patients overall. The Charlson comorbidity index score was positively associated with ASD (stages III-IV) of breast cancer but was inversely associated with ASD of lung cancer (pinteraction = 0.004). Regarding specific comorbidities, diabetes was positively associated with ASD (OR = 1.17, 95%CI = 1.09-1.26), whereas myocardial infarction was inversely associated with ASD (OR = 0.84, 95%CI = 0.75-0.95). The association between renal disease and ASD differed by cancer type (pinteraction < 0.001). A positive association was found with prostate cancer (OR = 2.02, 95%CI = 1.58-2.59) and an inverse association with colorectal cancer (OR = 0.84, 95%CI = 0.70-1.00). In summary, certain comorbidities (e.g., diabetes) may be positively associated with ASD of several cancer types. It needs to be clarified whether closer monitoring for early cancer signs or screening in these patients is reasonable, considering the problem of over-diagnosis particularly relevant in patients with short remaining life expectancy such as those with comorbidities. Also, evaluation of the cost-benefit relationship of cancer screening according to the type and severity of comorbidity (rather than summary scores) may be beneficial for personalized cancer screening in populations with chronic diseases.

Abstract
OBJECTIVE Timely diagnosis of cancer is important for prognosis. Patients' health literacy (HL) may impact differences of diagnostic delays. Thus, we aim to explore the association between HL and diagnostic intervals in cancer. METHODS Questionnaire data were obtained from patients with cancer diagnosed in 2016 and their general practitioner (n = 3890). The primary care interval (PCI) and the diagnostic interval (DI) were calculated using dates from national registries and questionnaires. A long PCI and DI were defined as ≥75th percentile. HL was assessed using scales from the Health Literacy Questionnaire: engaging with healthcare providers (scale 6:Engagement, n = 3008), navigating in healthcare (scale 7:Navigation, n = 2827) and understanding health information (scale 9:Knowledge, n = 3002). Low HL was defined as a score ≤3. RESULTS Low HL was reported by 12.2% (Engagement), 27.0% (Navigation) and 9.3% (Knowledge) of the patients and associated with a long PCI after adjustment of socio-economic factors: Engagement (prevalence rate ratio [PRR] 1.27 [95% CI 1.01-1.60]), Navigation (PRR 1.41 [95% CI 1.10-1.80]) and Knowledge (PRR 1.32 [95% CI 1.03-1.68]). No association was found between HL and DI. CONCLUSION HL may interfere with the diagnostic processes in general practice. Efforts to manage low HL include GPs' awareness of patients' ability to explain and respond to bodily changes and use of corresponding safety-netting strategies.

Abstract
The incidence of lung cancer is affected by air pollution, especially in high-density urban areas with heavy road traffic and dense urban form. Several studies have examined the direct relationship between lung cancer incidence and road traffic as well as urban form. However, the results are still inconsistent for high-density urban areas. This study focused on urban form and road traffic, aiming at revealing their relationship with lung cancer incidence in high-density urban areas at the neighborhood level. For this, an ecological study was conducted in downtown Shanghai to identify important indicators and explore quantitative associations. Negative binomial regression was fitted with lung cancer incidence as the dependent variable. The independent variables included indicators for road traffic and urban form, greenness, demographic, and socio-economic factors. The results showed that building coverage, averaged block perimeter area ratio, density of metro station without the glass barrier system, and the percentage of low-quality residential land were positively correlated with lung cancer incidence in the neighborhood, while population density was negatively correlated with lung cancer incidence. This study found a strong self-selection effect of socio-economic factors in the relationship between lung cancer incidence and greenness. These results may be useful for conducting health impact assessments and developing spatial planning interventions for respiratory health in high-density urban areas.

Abstract
Objective This research describes the clinical pathway and characteristics of two cohorts of patients. The first cohort consists of patients with a confirmed diagnosis of lung cancer while the second consists of patients with a solitary pulmonary nodule (SPN) and no evidence of lung cancer. Linked data from an electronic medical record and the Louisiana Tumor Registry were used in this investigation. Materials and methods REACHnet is one of 9 clinical research networks (CRNs) in PCORnet®, the National Patient-Centered Clinical Research Network and includes electronic health records for over 8 million patients from multiple partner health systems. Data from Ochsner Health System and Tulane Medical Center were linked to Louisiana Tumor Registry (LTR), a statewide population-based cancer registry, for analysis of patient’s clinical pathways between July 2013 and 2017. Patient characteristics and health services utilization rates by cancer stage were reported as frequency distributions. The Kaplan-Meier product limit method was used to estimate the time from index date to diagnosis by stage in lung cancer cohort. Results A total of 30,559 potentially eligible patients were identified and 2929 (9.58%) had primary lung cancer. Of these, 1496 (51.1%) were documented in LTR and their clinical pathway to diagnosis was further studied. Time to diagnosis varied significantly by cancer stage. A total of 24,140 patients with an SPN were identified in REACHnet and 15,978 (66.6%) had documented follow up care for 1 year. 1612 (10%) had no evidence of any work up for their SPN. The remaining 14,366 had some evidence of follow up, primarily office visits and additional chest imaging. Conclusion In both cohorts multiple biopsies were evident in the clinical pathway. Despite clinical workup, 70% of patients in the lung cancer cohort had stage III or IV disease. In the SPN cohort, only 66% were identified as receiving a diagnostic work-up.

Cancers (Basel) 2021; 13:cancers13050933. [PMID: 33668089 PMCID: PMC7956180 DOI: 10.3390/cancers13050933] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2021] [Revised: 02/16/2021] [Accepted: 02/18/2021] [Indexed: 12/24/2022] Open
Abstract
Background: Socio-economic position is associated with cancer incidence, but the direction and magnitude of this relationship differs across cancer types, geographical regions, and socio-economic parameters. In this nationwide cohort study, we evaluated the association between different individual-level socio-economic and -demographic factors, cancer incidence, and stage at diagnosis in Belgium. Methods: The 2001 census was linked to the nationwide Belgian Cancer Registry for cancer diagnoses between 2004 and 2013. Socio-economic parameters included education level, household composition, and housing conditions. Incidence rate ratios were assessed through Poisson regression models. Stage-specific analyses were conducted through logistic regression models. Results: Deprived groups showed higher risks for lung cancer and head and neck cancers, whereas an inverse relation was observed for malignant melanoma and female breast cancer. Typically, associations were more pronounced in men than in women. A lower socio-economic position was associated with reduced chances of being diagnosed with known or early stage at diagnosis; the strongest disparities were found for male lung cancer and female breast cancer. Conclusions: This study identified population groups at increased risk of cancer and unknown or advanced stage at diagnosis in Belgium. Further investigation is needed to build a comprehensive picture of socio-economic inequality in cancer incidence.

Abstract
BACKGROUND Rehabilitation and palliative care may play an important role in addressing the problems and needs perceived by socioeconomically disadvantaged patients with advanced cancer. However, no study has synthesized existing research on rehabilitation and palliative care for socioeconomically disadvantaged patients with advanced cancer. The study aimed to map existing research of rehabilitation and palliative care for patients with advanced cancer who are socioeconomically disadvantaged. MATERIAL AND METHODS A scoping review was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). A systematic literature search was performed in CINAHL, PubMed and EMBASE. Two reviewers independently assessed abstracts and full-text articles for eligibility and performed data extraction. Both qualitative and quantitative studies published between 2010 and 2019 were included if they addressed rehabilitation or palliative care for socioeconomically disadvantaged (adults ≥18 years) patients with advanced cancer. Socioeconomic disadvantage is defined by socioeconomic position (income, educational level and occupational status). RESULTS In total, 11 studies were included in this scoping review (138,152 patients and 45 healthcare providers) of which 10 were quantitative studies and 1 was a qualitative study. All included studies investigated the use of and preferences for palliative care, and none focused on rehabilitation. Two studies explored health professionals' perspectives on the delivery of palliative care. CONCLUSION Existing research within this research field is sparse. Future research should focus more on how best to reach and support socioeconomically disadvantaged people with advanced cancer in community-based rehabilitation and palliative care.

Abstract
Objective: Lung cancer is the leading cause of cancer-related death worldwide. This population-based longitudinal study investigates survival rates and the burden of comorbidity before and after being diagnosed with lung cancer in Denmark. Methods: From the Danish National Patient Registry (NPR) and the Danish Civil Registration System (CPR), 53,749 patients with lung cancer were identified and matched with 214,304 controls on age, gender, region of residence and marital status in the period 1998-2010. From the NPR, data on survival and comorbidity, registered as ICD-10 diagnoses, were extracted. Comorbidity was assessed using the Deyo-Charlson comorbidity score (DCcs) and mortality using Kaplan-Meier survival curves. Results: 1-year survival rate for Danish lung cancer patients was 51.7 % (CI 51.3-52.1) and 5-year survival rate was 14.7 % (CI 14.3-15.0) compared to 96.8 % (CI 96.7-96.8) and 84.0 % (CI 83.9-84.2) for controls respectively. Overall, cases had significantly more comorbidity compared to controls before being diagnosed with lung cancer. Prior to being diagnosed with lung cancer, more cases than controls had been diagnosed with other malignancies (11.4 % vs 6.0 % p<0.005), diseases of the circulatory system (16.4 % vs 13.0 % p<0.005) and respiratory diseases (12.2 % vs 4.8 % p<0.005). Among lung cancer patients 21.8 % had a DCcs ≥ 1 compared to 13.3 % among controls (P<0.005). The 1-year survival for DCcs =0 was 54.8 % (CI 54.3-55.3) for lung cancer patients and 97.8 % (CI 97.7-97.9) for controls. Decreasing survival with increasing DCcs was found in both groups. Conclusion: This study provides unique nationwide comorbidity data on patients before and after being diagnosed with lung cancer. We found increased mortality with increasing comorbidity, however more pronounced among controls compared to patients with lung cancer.

Abstract
BACKGROUND In Scandinavia, there is a strong tradition for research and quality monitoring based on registry data. In Denmark, Norway and Sweden, 63 clinical registries collect data on disease characteristics, treatment and outcome of various cancer diagnoses and groups based on process-related and outcome-related variables. AIM We describe the cancer-related clinical registries, compare organizational structures and quality indicators and provide examples of how these registries have been used to monitor clinical performance, develop prediction models, assess outcome and provide quality benchmarks. Further, we define unmet needs such as inclusion of patient-reported outcome variables, harmonization of variables and barriers for data sharing. RESULTS AND CONCLUSIONS The clinical registry framework provides an empirical basis for evidence-based development of high-quality and equitable cancer care. The registries can be used to follow implementation of new treatment principles and monitor patterns of care across geographical areas and patient groups. At the same time, the lessons learnt suggest that further developments and coordination are needed to utilize the full potential of the registry initiative in cancer care.

Abstract
PURPOSE The 5-year survival rate of patients with lung cancer in China is < 20%, and predicting their prognosis is difficult. Here, we investigated the association between two common non-synonymous single-nucleotide polymorphisms (SNPs) in the excision repair cross-complementing 2 (ERCC2) genes (rs13181 and rs1799793) and the prognosis of patients with lung cancer. METHODS Genomic DNA was extracted from the blood samples of 839 patients with lung cancer and genotyped using the SNPscan technique. The association between patient prognosis and the ERCC2 genotype was analyzed using a multivariate Cox proportional hazards model adjusted for multiple potential confounders. RESULTS The presence of ERCC2 rs13181 T>G significantly increased the risk of death (adjust hazard ratio (HR) = 1.29, 95% CI: 1.06-1.56, P = 0.009). Patients with the rs13181 TG genotype (adjust HR = 1.34, 95% CI: 1.08-1.65, P = 0.007) and rs13181 dominant mode TG+GG (adjust HR = 1.33, 95% CI: 1.08-1.63, P = 0.007) had significantly worse overall survival. Moreover, stratified analyses showed that patients with the TG and TG+GG rs13181 genotypes who were male, elderly (≥60 years), had a history of smoking, or without family history of malignant tumors had a significantly increased risk of death. In patients with adenocarcinoma lung cancer (ADC), the rs1799793 genotype CT (adjust HR = 1.49, 95% CI: 1.06-2.09, P = 0.023) and dominant model CT+TT (adjust HR = 1.45, 95% CI = 1.04-2.02, P = 0.027) were associated with an increased risk of death. CONCLUSION ERCC2 rs13181 and rs1799793 SNPs may be significant prognostic factors for the risk of death among patients with lung cancer.

Abstract
We aimed to investigate the conditional relative survival (CRS) and competing mortality in patients who underwent surgery for newly diagnosed lung cancer. Using a nationwide population-based database, we calculated 5-year CRS on 1 to 5 years survival after surgery. These rates were reported according to age, sex, socioeconomic status, comorbidities and treatment received. We also estimated cause-specific mortality with the consideration of competing risk. We identified 34 349 patients newly diagnosed with primary lung cancer from 2007 to 2013. The 5-year CRS after surgery was 71.7% at baseline improving steadily to 85.4% by 5 years, suggesting evidence of persistent excess mortality risk. Throughout the period, lung cancer was the most common cause of death, contributing to 83.6% mortality 1 year after surgery and 66.3% 5 years after surgery. Other causes of death included cardiovascular disease and respiratory disease, which increased continuously with time after surgery. CRS rates for patients with lung cancer improved over time but did not reach the level of the general population even 5 years after surgery. Although the main cause of death continues to be lung cancer, death from noncancer causes increased with time after surgery. Evidence-based decisions could be made on the dynamic risk profiles of the patients.

Abstract
OBJECTIVES Although it has been postulated that patients might benefit from the centralization of high-volume specialized centres, conflicting results have been reported on the relationship between the number of lung resections performed and the long-term, all-cause mortality rates among patients who underwent surgery for lung cancer. A population-based observational study was performed to contribute to the ongoing debate. METHODS The 2613 patients, all residents of the Lombardy region (Italy), who underwent lung resection for lung cancer from 2012 to 2014 were entered into the cohort and were followed until 2018. The hospitals were classified according to the annual number of pulmonary resections performed. Three categories of lung resection cases were identified: low (≤30), intermediate (31-95) and high (>95). The outcome of interest was all-cause death. A frailty model was used to estimate the death risk associated with the categories of numbers of lung resections performed, taking into account the multilevel structure of the data. A set of sensitivity analyses was performed to account for sources of systematic uncertainty. RESULTS The 1-year and 5-year survival rates of cohort members were 90% and 63%. Patients operated on in high-volume centres were on average younger and more often women. Compared to patients operated on in a low-volume centre, the mortality risk exhibited a significant, progressive reduction as the numbers of lung resections performed increased to intermediate (-13%; 95% confidence interval +10% to -31%) and high (-26%; 0% to -45%). Sensitivity analyses revealed that the association was consistent. CONCLUSIONS Further evidence that the volume of lung resection cases performed strongly affects the long-term survival of lung cancer patients has been supplied.

Abstract
Introduction Socioeconomic disparities have been linked to survival differences in patients with lung cancer. Swedish healthcare is tax-funded and provides equal access to care, therefore, survival following lung cancer surgery should be unrelated to household income. The aim of this study was to investigate the association between household disposable income and survival following surgery for lung cancer in Sweden. Methods We conducted a nationwide population-based cohort study including all patients who underwent pulmonary resections for lung cancer in Sweden 2008–2017. Individual-level record linkages between national quality and health-data registers were performed to acquire information regarding socioeconomic status and medical history. Cox regression by quintiles of household disposable income was used to estimate the adjusted risk for all-cause mortality. Results We included 5500 patients and the age-adjusted and sex-adjusted incidence rate of death per 100 person-years was 15 and 9.4 in the lowest and highest income quintile, respectively (mean follow-up time 3.2 years). Deprived patients were older, had more comorbidities and were less likely to have preoperative positron emission tomography or minimally invasive surgery, compared with patients with higher income. The adjusted HR for death was 0.77 (95% CI: 0.62 to 0.96) for the highest income quintile compared with the lowest. Conclusions We found an association between household disposable income and survival in patients who underwent surgery for lung cancer in Sweden, despite tax-funded universal health coverage. The association remained after adjustment for differences in baseline characteristics.

Abstract
AIMS Non-communicable diseases (NCDs) have become a primary health concern for most countries around the world. The aim of this research is to analyze the relevant evidence that determines the effect of socioeconomic position (SEP) on the incidence and prevalence of NCDs. METHODS A systematic literature search was performed using PubMed, Cochrane Library, and Web of Science to identify evidence regarding the relationship between income inequalities and NCDs, between 2005 and 2015. The final selection of papers was based on applied studies focusing on Organisation for Economic Co-operation and Development (OECD) countries and articles referring to three main groups of chronic diseases: cardiovascular and heart diseases, cancer, and diabetes. RESULTS A final set of 47 selected studies were fully taken into account in this review. Despite significant heterogeneity in exposure and outcomes measures, overall the evidence suggests that having low SEP increases the risk of developing cardiovascular diseases (CVDs), lung and breast cancer, and type 2 diabetes. SEP is also associated with multiple NCD risk factors such as smoking and physical inactivity. CONCLUSION Low socioeconomic status appears to have a significant consistent impact on mortality and morbidity caused by NCDs in OECD countries. Social and economic disadvantages are associated with health inequalities in terms of access to care, increased incident risk of NCDs, and early death. These findings point to the need for public health strategies and research to address socioeconomic status disparity among individuals.

Abstract
PURPOSE We investigated the association between comorbidities and stage at diagnosis among NSCLC patients in the US Military Health System (MHS), which provides universal health care to its beneficiaries. METHODS The linked data from the Department of Defense's Central Cancer Registry (CCR) and the MHS Data Repository (MDR) were used. The study included 4768 patients with histologically confirmed primary NSCLC. Comorbid conditions were extracted from the MDR data. Comorbid conditions were those included in the Charlson Comorbidity Index (CCI) and were defined as a diagnosis during a 3-year time frame prior to the NSCLC diagnosis. Multivariable logistic regression was performed to estimate odds ratios (ORs) and 95% confidence intervals (95% CI) of late stage (stages III and IV) versus early stage (stages I and II) in relation to pre-existing comorbidities. RESULTS Compared to patients with no comorbidities, those with prior comorbidities tended to be less likely to have lung cancer diagnosed at late stage. When specific comorbidities were analyzed, decreased odds of being diagnosed at late stage were observed among those with chronic obstructive pulmonary disease (COPD) (adjusted OR 0.78, 95% CI 0.68 to 0.90). In contrast, patients with a congestive heart failure or a liver cirrhosis/chronic hepatitis had an increased likelihood of being diagnosed at late stage (adjusted OR 1.30, 95% CI 1.00 to 1.69 and adjusted OR 1.87, 95% CI 1.24 to 2.82, respectively). CONCLUSIONS Among NSCLC patients in an equal access health system, the likelihood of late stage at diagnosis differed by specific comorbid diseases.

Reasons for prolonged time for diagnostic workup for stage I-II lung cancer and estimated effect of applying an optimized pathway for diagnostic procedures. BMC Health Serv Res 2019; 19:679. [PMID: 31533705 PMCID: PMC6751647 DOI: 10.1186/s12913-019-4517-z] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2018] [Accepted: 09/09/2019] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND Minimizing the time until start of cancer treatment is a political goal. In Norway, the target time for lung cancer is 42 days. The aim of this study was to identify reasons for delays and estimate the effect on the timelines when applying an optimal diagnostic pathway. METHODS Retrospective review of medical records of lung cancer patients, with stage I-II at baseline CT, receiving curative treatment (n = 100) at a regional cancer center in Norway. RESULTS Only 40% started treatment within 42 days. The most important delays were late referral to PET CT (n = 27) and exercise test (n = 16); repeated diagnostic procedures because bronchoscopy failed (n = 15); and need for further investigations after PET CT (n = 11). The time from referral to PET CT until the final report was 20.5 days in median. Applying current waiting time for PET CT (≤7 days), 48% would have started treatment within 42 days (p = 0.254). "Optimal pathway" was defined as 1) referral to PET CT and exercise test immediately after the CT scan and hospital visit, 2) tumor board discussion to decide diagnostic strategy and treatment, 3) referral to surgery or curative radiotherapy, 4) tissue sampling while waiting to start treatment. Applying the optimal pathway, current waiting time for PET CT and observed waiting times for the other procedures, 80% of patients could have started treatment within 42 days (p < 0.001), and the number of tissue sampling procedures could have been reduced from 112 to 92 (- 16%). CONCLUSION Changing the sequence of investigations would significantly reduce the time until start of treatment in curative lung cancer patients at our hospital and reduce the resources needed.

Abstract
Background: Socioeconomic inequality in survival after cancer have been reported in several countries and also in Denmark. Changes in cancer diagnostics and treatment may have changed the gap in survival between affluent and deprived patients and we investigated if the differences in relative survival by income has changed in Danish cancer patients over the past 25 years. Methods: The 1- and 5-year relative survival by income quintile is computed by comparing survival among cancer patients diagnosed 1987-2009 to the survival of a cancer-free matched sample of the background population. The comparison is done within the 15 most common cancers and all cancers combined. The gap in relative survival due to socioeconomic inequality for the period 1987-1991 is compared the period 2005-2009. Results: The relative 5-year survival increased for all 15 cancer sites investigated in the study period. In general, low-income patients diagnosed in 1987-1991 had between 0% and 11% units lower 5-year relative survival compared with high-income patients; however, only four sites (breast, prostate, bladder and head & neck) were statistically different. In patients diagnosed 2005-2009, the gap in 5-year RS was ranging from 2% to 22% units and statistically significantly different for 9 out of 15 sites. The results for 1-year relative survival were similar to the 5-year survival gap. An estimated 22% of all deaths at five years after diagnosis could be avoided had patients in all income groups had same survival as the high-income group. Conclusion: In this nationwide population-based study, we observed that the large improvements in both short- and long-term cancer survival among patients diagnosed 1987-2009. The improvements have been most pronounced for high-income cancer patients, leading to stable or even increasing survival differences between richest and poorest patients. Improving survival among low-income patients would improve survival rates among Danish cancer patients overall and reduce differences in survival when compared to other Western European countries.

Abstract
OBJECTIVES We examined associations between educational level and clinical presentation, patterns of management and mortality in patients with non-small cell lung cancer (NSCLC) in Sweden, a country with a National Health Care System. MATERIALS AND METHODS We identified 39,671 patients with a NSCLC diagnosis 2002-2016 in Lung Cancer Data Base Sweden (LCBaSe), a population-based research database. In analyses adjusted for comorbidity and other prognostic factors, odds Ratios (OR) and hazard Ratios (HR) were estimated to examine associations between patients' educational level and aspects of management and mortality. RESULTS Stage at diagnosis and waiting times did not differ between educational groups. In multivariable analysis, the likelihood to undergo PET/CT and assessment in a multidisciplinary team setting were higher in patients with high compared to low education (aOR 1.14; CI 1.05-1.23 and aOR 1.22; CI 1.14-1.32, respectively). In patients with early stage IA-IIB disease, the likelihood to undergo stereotactic radiotherapy was elevated in patients with high education (aOR 1.40; CI 1.03-1.91). Both all-cause (aHR 0.86; CI 0.77-0.92) and cause-specific mortality (aHR 0.83; CI 0.74-0.92) was lower in patients with high compared to low education in early stage disease (IA-IIB). In higher stage NSCLC no differences were observed. Patterns were similar in separate assessments stratified by sex and histopathology. CONCLUSIONS While stage at diagnosis and waiting times did not differ between educational groups, we found socioeconomic differences in diagnostic intensity, multidisciplinary team assessment, stereotactic radiotherapy and mortality in patients with NSCLC. These findings may in part reflect social gradients in implementation and use of novel diagnostic and treatment modalities. Our findings underscore the need for improved adherence to national guidelines.

Abstract
The effect of comorbidity on lung cancer patients' survival has been widely reported. The aim of this study was to investigate the effects of comorbidity on the establishment of the diagnosis of lung cancer and survival in lung cancer patients in Taiwan by using a nationwide population-based study design. This study collected various comorbidity patients and analyzed data regarding the lung cancer diagnosis and survival during a 16-year follow-up period (1995-2010). In total, 101,776 lung cancer patients were included, comprising 44,770 with and 57,006 without comorbidity. The Kaplan-Meier analyses were used to compare overall survival between lung cancer patients with and without comorbidity. In our cohort, chronic bronchitis patients who developed lung cancer had the lowest overall survival in one (45%), five (28.6%), and ten years (26.2%) since lung cancer diagnosis. Among lung cancer patients with nonpulmonary comorbidities, patients with hypertension had the lowest overall survival in one (47.9%), five (30.5%), and ten (28.2%) years since lung cancer diagnosis. In 2010, patients with and without comorbidity had 14.86 and 9.31 clinical visits, respectively. Lung cancer patients with preexisting comorbidity had higher frequency of physician visits. The presence of comorbid conditions was associated with early diagnosis of lung cancer.

Abstract
Historically, non-small-cell lung cancer (NSCLC) patients who are non-white, have low incomes, low educational attainment, and non-private insurance have worse survival. We assessed whether differences in survival were attributable to sociodemographic factors, clinical characteristics at diagnosis, or treatments received. We surveyed a multiregional cohort of patients diagnosed with NSCLC from 2003 to 2005 and followed through 2012. We used Cox proportional hazard analyses to estimate the risk of death associated with race/ethnicity, annual income, educational attainment, and insurance status, unadjusted and sequentially adjusting for sociodemographic factors, clinical characteristics, and receipt of surgery, chemotherapy, and radiotherapy. Of 3250 patients, 64% were white, 16% black, 7% Hispanic, and 7% Asian; 36% of patients had incomes <$20 000/y; 23% had not completed high school; and 74% had non-private insurance. In unadjusted analyses, black race, Hispanic ethnicity, income <$60 000/y, not attending college, and not having private insurance were all associated with an increased risk of mortality. Black-white differences were not statistically significant after adjustment for sociodemographic factors, although patients with patients without a high school diploma and patients with incomes <$40 000/y continued to have an increased risk of mortality. Differences by educational attainment were not statistically significant after adjustment for clinical characteristics. Differences by income were not statistically significant after adjustment for clinical characteristics and treatments. Clinical characteristics and treatments received primarily contributed to mortality disparities by race/ethnicity and socioeconomic status in patients with NSCLC. Additional efforts are needed to assure timely diagnosis and use of effective treatment to lessen these disparities.

Abstract
The incidence and mortality from lung cancer is decreasing in the US due to decades of public education and tobacco control policies, but are increasing elsewhere in the world related to the commencement of the tobacco epidemic in various countries and populations in the developing world. Individual cigarette smoking is by far the most common risk factor for lung carcinoma; other risks include passive smoke inhalation, residential radon, occupational exposures, infection and genetic susceptibility. The predominant disease burden currently falls on minority populations and socioeconomically disadvantaged people. In the US, the recent legalization of marijuana for recreational use in many states and the rapid growth of commercially available electronic nicotine delivery systems (ENDS) present challenges to public health for which little short term and no long term safety data is available.

Abstract
Occupational lung cancers are under-reported and under-compensated worldwide. We assessed systematic screening for occupational exposure to carcinogens combining a self-administered questionnaire and an occupational consultation to improve the detection of occupational lung cancers and their compensation. Social deprivation and the costs of this investigation were estimated. Patients with lung cancer received a self-administered questionnaire to collect their job history, potential exposure to carcinogens and deprivation. A physician assessed the questionnaire and recommended an occupational consultation if necessary. During the consultation, a physician assessed if the lung cancer was work-related and, if it was, delivered a medical certificate to claim for compensation. Over 18 months, 440 patients received the self-administered questionnaire: 234 returned a completed questionnaire and a consultation was required for 120 patients. Compensation was judged possible for 41 patients. Among the 35 medical certificates delivered, 19 patients received compensation. Nearly half the patients (46%) were assessed as socially deprived and these patients took significantly longer to return the questionnaire compared with those who were not deprived. The mean cost of the process was €62.65 per patient. Our results showed a systematic self-administered questionnaire can be used to identify patients potentially exposed to carcinogens and to improve compensation.

Abstract
Cancer diagnosis at an early stage increases the chance of curative treatment and of survival. It has been suggested that delays on the pathway from first symptom to diagnosis and treatment may be socio-economically patterned, and contribute to socio-economic differences in receipt of treatment and in cancer survival. This review aimed to assess the published evidence for socio-economic inequalities in stage at diagnosis of lung cancer, and in the length of time spent on the lung cancer pathway. MEDLINE, EMBASE and CINAHL databases were searched to locate cohort studies of adults with a primary diagnosis of lung cancer, where the outcome was stage at diagnosis or the length of time spent within an interval on the care pathway, or a suitable proxy measure, analysed according to a measure of socio-economic position. Meta-analysis was undertaken when there were studies available with suitable data. Of the 461 records screened, 39 papers were included in the review (20 from the UK) and seven in a final meta-analysis for stage at diagnosis. There was no evidence of socio-economic inequalities in late stage at diagnosis in the most, compared with the least, deprived group (OR=1.04, 95% CI=0.92 to 1.19). No socio-economic inequalities in the patient interval or in time from diagnosis to treatment were found. Socio-economic inequalities in stage at diagnosis are thought to be an important explanatory factor for survival inequalities in cancer. However, socio-economic inequalities in stage at diagnosis were not found in a meta-analysis for lung cancer. PROSPERO PROTOCOL REGISTRATION NUMBER CRD42014007145.

Abstract
BACKGROUND Access to specialty care is critical for patients with advanced stage lung cancer. This study assessed access to cancer specialists and cancer treatment in a broad population of patients with advanced stage lung cancer. MATERIALS AND METHODS Two study samples were extracted from 2 claims databases and analyzed independently: patients aged ≥ 18 years with de novo diagnosis of metastatic lung cancer in the MarketScan database between 2008 and 2014 (commercially insured adult patients; n = 22,268); and patients aged ≥ 65 years in the Surveillance, Epidemiology, and End Results-Medicare database with a diagnosis of advanced non-small-cell lung cancer between 2007 and 2011 (Medicare-insured elderly patients; n = 9651). The study period spanned from 6 weeks before the first lung biopsy tied to the initial lung cancer diagnosis until the end of continuous health insurance enrollment, or data availability, or death. RESULTS Among the commercially insured adults (MarketScan), most patients were seen by a cancer specialist within a month of first lung biopsy (80%), 12% were never seen by a cancer specialist, and 6% did not receive cancer-directed therapy. Among the Medicare-insured elderly patients (SEER-Medicare), the proportions were 79%, 4%, and 10%, respectively. Patients seen by a cancer specialist were more likely to receive cancer-directed therapy (95% vs. 92%, P < .001 and 92% vs. 38%, P < .001, respectively). CONCLUSION Between 4% and 12% of patients with advanced stage lung cancer do not have appropriate access to cancer specialist, which appears to negatively affect access to optimal and timely treatment.

Abstract
Background Lung cancer is the second most frequent cancer diagnosis in Denmark. Although improved during the last decade, the prognosis of lung cancer is still poor with an overall 5-year survival rate of approximately 12%. Delay in diagnosis and treatment of lung cancer has been suggested as a potential cause of the poor prognosis and as consequence, fast track cancer care pathways were implemented describing maximum acceptable time thresholds from referral to treatment. In Denmark, patients with lung cancer are often transferred between hospitals with diagnostic facilities to hospitals with treatment facilities during the care pathway. We wanted to investigate whether this organizational set-up influenced the time that patients wait for the diagnosis and treatment. Therefore, the objective of this study was to uncover the impact of transfer between hospitals on the delay in the diagnosis and treatment of Non-Small Cell Lung Cancer (NSCLC). Methods We performed a historical prospective cohort study using data from the Danish Lung Cancer Registry (DLCR). All patients diagnosed with primary NSCLC from January 1st 2008 to December 31st 2012 were included. Patients with unresolved pathology and incomplete data on the dates of referral, diagnosis and treatment were excluded. Results A total of 11 273 patients were included for further analyses. Transfer patients waited longer for treatment after the diagnosis, (Hazard ratio (HR) 0.81 (0.68–0.96)) and in total time from referral to treatment (HR 0.84 (0.77–0.92)), than no-transfer patients. Transfer patients had lower odds of being diagnosed (Odds Ratio (OR) 0.82 (0.74–0.94) and treated (OR 0.66 (0.61–0.72) within the acceptable time thresholds described in the care pathway. Conclusion Fast track cancer care pathways were implemented to unify and accelerate the diagnosis and treatment of cancer. We found that the transfer between hospitals during the care pathway might cause delay from diagnosis to treatment as well as in the total time from referral to treatment in patients with Non Small-Cell Lung Cancer. The difference between no-transfer and transfer patients persists after adjusting for known predictors of delay.

Abstract
BACKGROUND Late effects after cancer diagnosis and treatment are common, but only few studies have examined the role of social factors in developing these late effects. The aim of this study was to examine the association between educational level and physical function and pain among cancer survivors two years after diagnosis. MATERIAL AND METHODS The study population consisted of adult Danish patients with a first-time cancer diagnosis who were sent a questionnaire in 2010 and followed up in 2012. In total, 4346 returned the first questionnaire shortly after diagnosis and 2568 returned the follow-up questionnaire. After exclusion of 177 due to missing information, we included 2391 cancer survivors in the analyses. Physical function and pain were measured using the EORTC QLQ-C30. Linear regression analyses were conducted separately for men and women, and adjusted for demographic and clinical characteristics. Additionally, analyses were stratified on comorbidity. RESULTS Differences in mean scores according to educational level were small. Physical function was better in women with medium (2.8; 95% CI 0.1;5.4) and higher education (3.4; 95% CI 0.9;5.9) compared to women with short education. In contrast, men with medium education reported lower physical function (-2.9; 95% CI -5.7;-0.1) than men with short education. Compared to women with short education, we found lower pain scores among women with medium (-5.0; 95% CI -8.7;-1.4) and higher education (-3.4; 95% CI -6.7;0.0). Similarly, men with higher education experienced lower pain score (-3.4; 95% CI -6.9;0.1) than men with short education. The role of educational level differed between those with and without comorbidity. CONCLUSION Educational level is slightly associated with physical function and pain among cancer survivors. However, mean differences in this study were small and below what is considered clinically relevant.

Abstract
OBJECTIVES The incidence of and survival from lung cancer are associated with socioeconomic position, and disparities have been observed in both curative and palliative treatment for lung cancer. 'Patient navigation' is valuable in addressing health disparity, with timely treatment and transition to care. We conducted a pilot study to test the feasibility of a patient navigator program (PAtient COach) for newly diagnosed lung cancer. We present the trial, the findings from the pilot study and discuss factors that might have affected recruitment rates. MATERIAL AND METHODS We invited 24 lung cancer patients referred for chemotherapy to the Oncology Department at Herlev University Hospital, Denmark, to participate in the pilot study. To be eligible, patients had to live alone, have no formal education beyond secondary school, have one or more comorbid conditions, have a performance status of 1 or 2 or be over 65 years of age. The patient navigators targeted four phases of treatment: planning, initiation, compliance and end of treatment. RESULTS Six months after the start of the study, we had recruited only six patients, due mainly to inherent patient resistance and because only 50% of eligible patients were invited. Of the 18 patients who did not wish to participate, 13 agreed to fill in a baseline questionnaire. The most frequent reason given for not wanting to participate was a belief that a patient navigator would be of no benefit. CONCLUSIONS The pilot study met a number of internal and external obstacles to patients' recruitment. The study provides insight into the barriers to recruitment of socially disadvantaged cancer patients to clinical trials and will inform future trial designs.

Abstract
Background The time from a referral for suspected lung cancer is received at a hospital until treatment start has been defined as a quality indicator. Current Norwegian recommendation is that ≥70% should start surgery or radiotherapy within 42 calendar days and systemic therapy within 35 days. However, delays can occur due to medical complexity. The aim of this study was to quantify the proportion of patients who started treatment within the recommended timeframes; and to assess the proportion of non-complex patients for which there were no good reasons for delays. Methods We performed a retrospective chart review of all patients diagnosed with lung cancer at a university hospital during 2011–2013. We defined “non-complex” patients as those who underwent ≤1 tissue diagnostic procedure and had no delays due to comorbidity, intercurrent disease or complications to diagnostic procedures (“Medical delays”) of more than three days. Results Four hundred forty-nine cases were analyzed; 142 (32%) had >1 tissue diagnostic procedures; 67 (15%) had medical delays >3 days; 262 (58%) were non-complex and 363 (81%) received treatment for lung cancer. Median number of days until surgery or radiotherapy was 48 (overall) and 41 (non-complex patients). The proportions who started surgery or radiotherapy within 42 days were 41% (overall) and 56% (non-complex). Corresponding numbers for systemic therapy were 29 days (overall) and 25 days (non-complex), and 64% (overall) and 80% (non-complex). Conclusion Fewer lung cancer patients than desired started treatment within the recommended timeframes. Even among the least complex patients, too few patients received timely treatment. The reasons need to be identified and understood, and changes in the organization appear to be necessary in order to offer timely treatment to more patients.

Abstract
OBJECTIVE When using area-level disadvantage measures, size of geographic unit can have major effects on recorded socioeconomic cancer disparities. This study examined the extent of changes in recorded socioeconomic inequalities in cancer survival and distant stage when the measure of socioeconomic disadvantage was based on smaller Census Collection Districts (CDs) instead of Statistical Local Areas (SLAs). METHODS Population-based New South Wales Cancer Registry data were used to identify cases diagnosed with primary invasive cancer in 2000-2008 (n=264,236). Logistic regression and competing risk regression modelling were performed to examine socioeconomic differences in odds of distant stage and hazard of cancer death for all sites combined and separately for breast, prostate, colorectal and lung cancers. RESULTS For all sites collectively, associations between socioeconomic disadvantage and cancer survival and distant stage were stronger when the CD-based socioeconomic disadvantage measure was used compared with the SLA-based measure. The CD-based measure showed a more consistent socioeconomic gradient with a linear upward trend of risk of cancer death/distant stage with increasing socioeconomic disadvantage. Site-specific analyses provided similar findings for the risk of death but less consistent results for the likelihood of distant stage. CONCLUSIONS The use of socioeconomic disadvantage measure based on the smallest available spatial unit should be encouraged in the future. Implications for public health: Disadvantage measures based on small spatial units can more accurately identify socioeconomic cancer disparities to inform priority settings in service planning.

Abstract
Context The European Deprivation Index (EDI), is a new ecological estimate for Socio-Economic Status (SES). This study postulates that Time-To-Treatment could be used as a cancer quality-of -care surrogate in order to identify the association between cancer patient's SES and quality of care in a French comprehensive cancer center. Methods retrospective mono-centered cohort study. All consecutive incoming adult patients diagnosed for breast cancer(BC), prostate cancer(PC), colorectal cancer (CRC), lung cancer(LC) or sarcoma(S) were included between January 2013 and December 2013. The association of EDI and Time-To-Diagnosis(TTD), as well as Time-To-Treatment(TTT) was analyzed using a cox regression, and a strata analysis per tumor site was performed. Results 969 patients were included. Primitive tumor site was 505 BC(52%), 169 PC(17%), 145 LC(15%), 116 CRC(12%), and 34 S(4%). Median TTD was 1.41 months (Q1-Q3 0.5 to 3.5 months). Median TTT was 0.9 months (0.4 - 1.4). In a multivariate analysis, we identified the tumor site as a predictive factor to influence TTD, shorter for BC (0.75months, [0.30- 1.9]) than PC (4.69 months [1.6-29.7]), HR 0.27 95%CI= [0.22-0.34], p < 0.001. TTT was also shorter for BC (0.75months [0.4-1.1]) than PC (2.02 [0.9-3.2]), HR 0.32 95%CI= [0.27-0.39], p < 0.001. EDI quintiles were not found associated with either TTT or TTD. Conclusions Deprivation estimated by the EDI does not appear to be related to an extension of the Time-to-Diagnosis or Time-to-Treatment in our real-life population. Further research should be done to identify other frailty-sensitive factors that could be responsible for delays in care.

Abstract
Aim of database The Danish Lung Cancer Registry (DLCR) was established by the Danish Lung Cancer Group. The primary and first goal of the DLCR was to improve survival and the overall clinical management of Danish lung cancer patients. Study population All Danish primary lung cancer patients since 2000 are included into the registry and the database today contains information on more than 50,000 cases of lung cancer. Main variables The database contains information on patient characteristics such as age, sex, diagnostic procedures, histology, tumor stage, lung function, performance, comorbidities, type of surgery, and/or oncological treatment and complications. Since November 2013, DLCR data on Patient -Reported Outcome Measures is also included. Descriptive data Results are primarily reported as quality indicators, which are published online monthly, and in an annual report where the results are commented for local, regional, and national audits. Indicator results are supported by descriptive reports with details on diagnostics and treatment. Conclusion DLCR has since its creation been used to improve the quality of treatment of lung cancer in Denmark and it is increasingly used as a source for research regarding lung cancer in Denmark and in comparisons with other countries.

Abstract
Background One fifth of all deaths among children in Europe are accounted for by cancer. If this is to be reduced there is a need for studies on not only biology and treatment approaches but also on how social factors influence cure rates. We investigated how various socioeconomic characteristics were associated with survival after childhood cancer. Material and methods In a nationwide cohort of 3797 children diagnosed with cancer [hematological cancer, central nervous system (CNS) tumors, non-CNS solid tumors] before age 20 between 1990 and 2009 we identified parents and siblings and obtained individual level parental socioeconomic variables and vital status through 2012 by linkage to population-based registries. Hazard ratios (HR) and 95% confidence intervals (CI) for dying were estimated using multivariate Cox proportional hazard models. Results For all children with cancer combined, survival was slightly but not statistically significantly better the higher the education of the mother or the father, and with maternal income. Significantly better survival was observed when parents were living together compared to living alone and worse survival when the child had siblings compared to none. Young (<20) or older (≥40) maternal age showed non-significant associations, but based on small numbers. For hematological cancers, no significant associations were observed. For CNS tumors, better survival was seen with parents living together (HR 0.70, CI 0.51-0.97). For non-CNS solid tumors, survival was better with high education of the mother (HR 0.66, CI 0.44-0.99) compared to basic and worse for children with one (HR 1.45, CI 1.11-1.89) or two or more siblings (HR 1.29, CI 0.93-1.79) (p for trend 0.02) compared to none. Conclusion The impact of socioeconomic characteristics on childhood cancer survival, despite equal access to protocolled and free-of-charge treatment, warrants further and more direct studies of underlying mechanisms in order to target these as a means to improve survival rates.

Abstract
BACKGROUND Several studies have documented an association between socioeconomic position and survival from gynaecological cancer, but the mechanisms are unclear. OBJECTIVE The aim of this study was to examine the association between level of education and survival after endometrial cancer among Danish women; and whether differences in stage at diagnosis and comorbidity contribute to the educational differences in survival. METHODS Women with endometrial cancer diagnosed between 2005 and 2009 were identified in the Danish Gynaecological Cancer Database, with information on clinical characteristics, surgery, body mass index (BMI) and smoking status. Information on highest attained education, cohabitation and comorbidity was obtained from nationwide administrative registries. Logistic regression models were used to determine the association between level of education and cancer stage and Cox proportional hazards model for analyses of overall survival. RESULTS Of the 3638 patients identified during the study period, 787 had died by the end of 2011. The group of patients with short education had a higher odds ratio (OR) for advanced stage at diagnosis, but this was not statistically significant (adjusted OR 1.20; 95% CI 0.97-1.49). The age-adjusted hazard ratio (HR) for dying of patients with short education was 1.47 (CI 95% 1.17-1.80). Adjustment for cohabitation status, BMI, smoking and comorbidity did not change HRs, but further adjustment for cancer stage yielded a HR of 1.36 (1.11-1.67). CONCLUSION Early detection in all educational groups might reduce social inequalities in survival, however, the unexplained increased risk for death after adjustment for prognostic factors, warrants increased attention to patients with short education in all age groups throughout treatment and rehabilitation.
