NOTE: This is an unreviewed Preprint

Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note “no longer under consideration” will appear above).

Peer-review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a “Peer-Review Me” button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.

Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).

Final version: If our system detects a final peer-reviewed “version of record” (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.

Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.

Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.

Risk factors identifying of lung cancer in the elderly: using deep learning method based on open survey data from 1996 to 2017

Lung cancer is one of the most dangerous malignant tumors to human health, which morbidity and mortality are growing fastest, especially in the elderly. With rapid growth of the elderly population in recent years, the lung cancer prevention and control is more and more serious.


The pathogenesis of lung cancer is a complex process involving a variety of risk factors. This study aims at identifying lung cancer risk factors of the elderly using deep learning method.


Based on open access data, we integrated multidisciplinary risk factors together, which included behavioral risk factors, disease history factors, environmental factors, demography factors and so on. We conducted data preprocessing work of these integrated data. Then deep neural network (DNN) models were trained of stratified elderly population. Risk factors of different stratification were extracted from these DNN models. Finally, quantitative analysis were conducted to identify risk factors of different groups.


The proposed method identified risk factors quantitatively of lung cancer incidence in different stratified elderly populations. Smoking was the leading cause of lung cancer incidence in the elderly. And men ≥65 years were more sensitive to smoking frequency than women. Cancer history played an important role in the incidence of lung cancer. Lung cancer incidence decreased more obviously in men than in women with stop smoking, especially non-small cell lung cancer (NSCLC) in elderly men.


This study demonstrates a risk factor identifying method of lung cancer incidence quantitatively in the elderly. We adopt deep neural network method in different stratified populations, which could reflect age and gender disparities. Our findings provide intervention indicators to prevent lung cancer in the elderly, especially in the older men.
