The researchers are studying improved screening techniques involving genetic testing and blood tests to determine the individuals with a higher risk of non-small cell lung cancer.

CT scan

The NCI-sponsored National Lung Screening Trial (NLST) has revealed the use of low dose CT scans for screening the non-small cell lung cancer among individuals having a history of heavy smoking. This screening technique has minimized the higher risk of deaths among non-small cell lung cancer patients. The researchers are looking forward to refining the CT screening for predicting the occurrence of cancer.

Machine learning

The advanced digital technology integrates computers to determine the prediction of some of the significant outcomes. The researchers use computer algorithms to develop computer-aided programs capable of identifying non-small cell lung cancer through CT scans rather than communicating with the radiologists or pathologists. Additionally, the artificial intelligence study has revealed that the researchers have provided practical training regarding computer programs for diagnosing the types of lung cancer, showing the accuracy of 97% along with detection of cancer-related genetic mutations. 

Eliminating tobacco consumption

Although there are several methods for the early detection and treatment of non-small cell lung cancer. The adoption of interventions and programs such as stopping smoking and tobacco consumption is thought as the best method to save lives. As it motivates the individuals who do not have the smoking habit and if they possess, they additionally tend to quit this habit. The finishing of smoking habits among non-small cell lung cancer patients have shown efficacy in improving their quality of life, minimizing the side effects and lowering their chance of relapsing towards non-small cell lung cancer. The healthcare team has contributed to eliminating tobacco consumption among chronic smokers who are already suffering from non-small cell lung cancer while enhancing nicotine replacement and other related methods. Also, several other research studies are underway for helping non-small cell lung cancer patients to eliminate tobacco consumption.

Palliative care or supportive care

Several clinical trials are underway to find out more effective ways for treating non-small cell lung cancer that improve the patients’ quality of life and also provide them with a comfortable living environment.

NCI-supported research programs

Several NCI-funded researchers at the NIH campus and regions across the globe have also been integrating towards adopting different techniques for combating the issues of non-small cell lung cancer. Some of the past research is basic while exploring additional questions on the same is the biological underpinnings of cancer and determining related social factors that affect cancer risk. Some research tends to be more clinical, translating the essential information into improved patient outcomes.

 Additionally, ALCHEMIST is a multicenter NCI trial that began in 2014 for patients diagnosed with early stages of non-small cell lung cancer. It aims to check the determination of the addition of targeted therapy after surgery depending upon the genetics of a patient’s tumor that also helps improve the survival rate. 

Lung-MAP trial

Lung-MAP trial is known to be the ongoing multicenter trial conducted for non-small cell lung cancer patients suffering from advanced non-small cell lung cancer and also who did not respond to any prior treatment. In this trial, the non-small cell lung cancer patients are mainly assigned to particular targeted therapy depending upon the genetic makeup of the tumor cell.

Small Cell Lung Cancer Consortium has also contributed to coordinating efforts and provided a network for small cell lung cancer investigators focusing on preclinical studies of non-small cell lung cancer.

NCI has provided funds for five lung cancer Specialized Programs of Research Excellence (Lung SPOREs). Moreover, these programs majorly contribute to sorting out the primary scientific findings into clinical settings. Each SPORE has multiple lung cancer projects underway.

Clinical trials

Additionally, the NCI have provided several funds across the globe regarding the determination of early- and late-phase clinical trials that contributed to the development of new treatments and improving the care quality among non-small cell lung cancer patients.
