Background: Although lung cancer (LC) continues to be one of the leading<br />

causes of cancer morbidity and mortality world-wide, the NLST trial showed<br />

that low dose computed tomography (LDCT) screening can substantially<br />

reduce mortality in specific high-risk populations. However, most individuals<br />

are not making informed decisions which take into account the risks of<br />

screening although US guidelines advocate for informed decision-making. We<br />

report preliminary results of a web-based interactive LC decision aid (LuCaS<br />

DA) on LC screening knowledge and decision making compared to the US<br />

National Cancer Institutes’ web-pages on LC screening. Methods: Individuals<br />

in the study (n=50; from rural Kentucky and SE Florida, USA) had an elevated<br />

risk for lung cancer (n=50) due to smoking. Participants completed a baseline<br />

survey and were randomized to viewing the LuCaS DA or the NCI website.<br />

After 2 weeks, participants completed an online survey. Surveys collected<br />

information on: demographics, health status, smoking history, knowledge of<br />

CT screening, decisions about being screened for lung cancer, and decisional<br />

conflict about screening. Results: Participants were 52.6 (SD 5.1) years old<br />

on average; were majority female (77.1%), White (62.0%), and non-Hispanic<br />

(83.7%), and reported have some insurance coverage (88.0%). Most were<br />

current daily smokers (70.2%), and overall had smoked an average of 27.9<br />

(SD 7.7) years. Mean Decisional Conflict overall participants was 39.3 (SD<br />

13.5) at baseline and 34.4 (SD 11.1) at 2 week follow up, with no differences<br />

between the arms. The percentage of participants show stated that they had<br />

made a decision about screening increased slightly from 32.7% at baseline<br />

to 37.5% at follow up. Preparedness for making a decision about screening<br />

(measured POST only) showed no differences between the arms. There were<br />

some increases in knowledge about CT screening and knowledge about LCS<br />

guidelines from initial to 2-week follow up. Finally, a qualitative exploration<br />

of the LuCaS DA showed that it had high levels of acceptability. Conclusion:<br />

DAs can facilitate informed decisions about participation in cancer screening,<br />

and US policies have required their use. This is the first study that we are<br />

aware of that assesses the use and effects of a lung cancer screening decision<br />

aid. These preliminary results show that the LuCaS DA can improve some<br />

outcomes, but not consistently more than the NCI webpages. Additional<br />

analyses will include the full sample of participants, evaluate a broader array<br />

of decision and behavioral outcomes, and consider longer term outcomes of<br />

the LuCaS DA.<br />

Background: Complexities such as addressing indeterminate pulmonary<br />

nodules (IPNs) are an inherent part of a lung screening program, and defining<br />

which individuals will benefit from invasive intervention is not always<br />

known. With the goal of combining non-invasive biomarkers with imaging<br />

to more definitively stratify patients, we initiated an investigational<br />

biospecimen collection process into our lung screening program. Ultimately,<br />

these biomarkers may improve specificity within the screening population,<br />

thereby reducing the overall cost and potential morbidity from false positive<br />

results of low-dose computed tomography scan (LDCT) screening. Studies<br />

like this are important to the ongoing improvement of lung cancer screening.<br />

Methods: NCCN high-risk individuals enrolled in a high volume clinical lung<br />

screening program were introduced to our IRB approved research biospecimen<br />

study at the time of the scheduling of their LDCT. Patients were consented,<br />

and routine biospecimens were collected by research staff at the time of<br />

their LDCT scan, including nasal epithelial brushings, buccal swabs and<br />

blood. When available, additional biospecimens consisting of bronchial<br />

airway brushings and tumor samples were collected from subjects who<br />

underwent diagnostic interventions for suspicion of malignancy. Results:<br />

Since 2012 there have been 3856 patients enrolled and 8776 LDCT scans<br />

to date with 100 lung cancer diagnoses within our lung screening program.<br />

In 2014, funding (LUNGevity and Robert E Wise grants) was obtained for<br />

biospecimen collection from subjects enrolled in our institutional LDCT<br />

screening program. Initial prospective collection of biospecimens was slower<br />

than anticipated due to various factors. After review of the process, a number<br />

of adjustments were made, which significantly increased enrollment. This<br />

included implementation of a multidisciplinary taskforce consisting of<br />

research and clinical staff committed to patient outreach and participation.<br />

To date, samples from approximately 1420 subjects have been collected.<br />

Of these, 268 (19%) were found to have newly detected IPNs measuring<br />

6-20mm on LDCT, and 28 samples were from patients with subsequent<br />

diagnoses of lung cancer. Conclusion: Successful coordination of biospecimen<br />

collection within a lung screening program is complex, but achievable with<br />

multidisciplinary coordination, and has great potential to help further<br />

stratify patients that may or may not benefit from invasive diagnostics and<br />

therapy. We demonstrate an established lung screening program that is<br />

successfully accruing to a prospective diagnostic study and share specific<br />

recommendations for how to successfully accrue in other programs.<br />

Background: Both morbidity and mortality of lung cancer ranks first in China.<br />

According to the “2012 cancer registration report of China”, Northeast China<br />

is a high prevalence area of lung cancer, so early diagnosis of lung cancer<br />

is particularly important. Based on this, we made the regional survey in<br />

Changchun city. (1) To investigate the incidence of pulmonary nodules and<br />

lung cancer in Changchun city. (2)To provide the foundation of large data<br />

study on early screening of lung cancer and disease control. Methods: Carry<br />

out the investigation of the people over 50 years of age in 10 communities in<br />

Changchun of Jilin Province (A total of 1461 people), including questionnaire,<br />

pulmonary function tests and low-dose spiral CT examination. The disease<br />

assessment and patient management are based on “Diagnosis and treatment<br />

of pulmonary nodules in Chinese expert consensus”. Results: The percentage<br />

of lung disease in the investigated population was 25.67%, and the<br />

constitution of the lung disease included: 30.67% of the lung nodules, 37.07%<br />

of chronic obstructive pulmonary disease, 18.67% of inflammation, 5.6% of<br />

the lung, 2.13% of pulmonary interstitial fibrosis, 2.13% of pleural effusion<br />

and 3.73% of other lung diseases. The number of pulmonary nodules was 115,<br />

accounting for 7.87% of the total number of screening, 89 cases of solitary<br />

nodules, 26 cases of multiple nodules. A total of 4 patients with lung cancer<br />

were confirmed by pathology, including 2 cases of adenocarcinoma, 1 cases of<br />

squamous cell carcinoma and 1 case of mucinous carcinoma of the lung. All of<br />

the cancer cases were solitary nodules, and accounted for 3.48% of the total<br />

samples. Among them, 3 patients are male with a history of smoking, and 1<br />

is female without any history of smoking. According to the nodule size, the<br />

diameters of nodule in 3 cases are greater than 8mm and 1 case is less than<br />

4mm. According to the quality of nodules, 3 cases are solid and mixed nodules,<br />

and 1 case is ground-glass opacity. Conclusion: (1)Smoking is a risk factor for<br />

lung cancer. (2) Solid and mixed character nodules in pulmonary nodules and<br />

larger diameter nodules are more likely to develop into cancer, so they should<br />

be strengthened management. (3) Low-dose spiral CT is helpful for early<br />

diagnosis of lung cancer.<br />
