In 2012, we conducted a study that revealed for the first time that a hidden negative bias existed towards lung cancer. Given positive external factors in lung cancer care in recent years, such as increased awareness of the disease and improvements in care, we recognized the need to conduct a follow-up study to assess potential changes in attitudes towards the disease.
The latest study findings are promising and show that attitudes towards people with lung cancer are improving.
While a negative bias still exists, the significant decrease in the number of people who associate lung cancer with shame, stigma, and hopelessness is encouraging. Past research in the field has shown implicit attitudes tend to remain stable over time, which makes this positive movement all the more important to understand and celebrate.
We also partnered with researchers at the Fred Hutchinson Cancer Research Center to quantify overall survival gains from 1990 to 2015 and determine how survival outcomes could be improved even further by increasing treatment rates.
The results were presented at the 2015 World Conference on Lung Cancer (WCLC) Meeting and published in The Oncologist.
What does this all mean?
Survival gains in lung cancer have been modest compared to other cancers, but new treatment options have increased the time people with advanced lung cancer survive. Improved treatment rates can significantly increase the years of life gained by the population.2
Scientists have made significant advancements in our understanding of lung cancer. For example, we now know that lung cancer is not one disease, but many. Different types of lung cancer are defined by the type of lung cell from which the cancer originates or by the genetics of the cancer, often referred to as biomarkers.3
Lung Cancer Biomarkers Today
As a result of the explosion of biomarker diversity, we have an unprecedented understanding of the many types of lung cancer. Today, more than half of lung cancers - representing more than 1 million people - are covered by known genetic biomarkers.
In addition, many people have lung cancer with known protein markers, such as PD-L1.

Evolution of Lung Cancer Diagnosis
The techniques that pathologists use to diagnose lung cancer and help oncologists determine treatment have changed as we have learned more about the underlying biology of the disease. For years, the only distinction doctors could make was whether a person had small cell or non-small cell lung cancer based on the size of cells in a tumor sample viewed under a microscope.
Today
That's changed with the development of immunohistochemistry and fluorescence in situ hybridization, which can be used to find specific genetic or protein biomarkers in a tumor samples to determine if a targeted treatment is appropriate.
The approval of a less invasive test called a "liquid biopsy" is also changing how lung cancer is diagnosed, by identifying cancer mutations through a blood-based test. Previously, the primary method used to identify lung cancer biomarkers was to remove cells directly from the lung and look at them under a microscope, a procedure called a biopsy.
More still needs to be done to substantially improve survival, from diagnosing lung cancer earlier to testing new medicines and combinations of medicines, and delivering the right treatment to the right person at the right time. We're heading in the right direction. Now is the time.
