New RWE Study Indicates Poor Prognosis for NSCLC Patients Despite Targeted Therapies
Lung cancer is the leading cause of cancer deaths in Finland, with a particularly poor prognosis for non-small cell lung cancer (NSCLC). It is often diagnosed at an advanced stage when treatment options are limited. A recently published retrospective registry-based real-world evidence (RWE) study on KRAS-mutated NSCLC patients in Finland addressed this issue.
Medaffcon’s study was the first of its kind in Finland. It demonstrated that lung cancer is at the forefront of medical advances, with genetic tests being routinely used, especially for NSCLC patients.
The field is developing rapidly. New genetic factors, targeted therapies, and immuno-oncological treatments are entering the market quickly, which are expected to lead to better treatment outcomes. This results in a highly complex and constantly changing treatment landscape. Therefore, understanding the subgroups of NSCLC patients and their outcomes in real-world settings is increasingly important.
The prognosis for non-small cell lung cancer remains poor despite the improvement in the prognosis for advanced NSCLC due to targeted therapies and immuno-oncological treatments. The need for personalised treatments is emphasised because genetic mutations significantly impact disease progression.
The study indicates that NSCLC imposes a substantial economic burden. This is influenced by the complexity of treatment, the need for long-term care, the use of new and expensive treatment modalities, and the impact of the disease and treatments on patients’ ability to work and quality of life.
Genetic Changes Play a Central Role in the Development of NSCLC
According to Riikka Mattila, PhD, Scientific Advisor at Medaffcon, genetic mutations, such as the KRAS mutation, play a central role in developing non-small cell lung cancer.
“Lung cancer is at the forefront of personalized treatment development. Therefore, gene panels are important. It is essential to test all patients. In this study, it was found that some patients were tested while others were not,” says Riikka Mattila.
The study identified 601 NSCLC patients, 64 % of whom were tested for genetic changes. Of those, 9 % had a KRAS G12C mutation. Common characteristics included younger age and smoking.
“In our analysis, these patients fared worse and had higher resource use. These factors correlated: worse disease required more treatment,” says Riikka Mattila from the Medaffcon.
KRAS G12C Stands Out Among Subgroups Regarding Overall Survival
Patients with KRAS mutations were often at a metastatic stage at the time of diagnosis, meaning the disease had progressed significantly and spread to other parts of the body, making it more challenging to manage. The disease is aggressive, and treatment prognoses are generally poor.
KRAS G12C, in particular, stood out from other subgroups. These patients had a shorter overall survival and used more healthcare resources than others.
In summary, the study’s results highlight the significant impact of KRAS mutations on clinical outcomes and the use of healthcare resources, especially emphasising the KRAS G12C mutation.
Study Highlights Finland’s Unique Research Environment
The study showed that lung cancer treatment is at the forefront of medical advances, with genetic tests and targeted therapies being routinely used, particularly for NSCLC patients.
The Medaffcon team included data scientists Anna Anttalainen and Samuli Tuominen and scientific advisor Riikka Mattila, PhD. The work is always done as a team, with the goal that the entire team is involved from the beginning of the project. If necessary, the expertise of the entire Medaffcon team is available.
Finland is also an exceptional country for research.
“We can combine all clinical data with social and healthcare data from deep genetic data in Finland. This cannot be done elsewhere,” says Riikka Mattila, Scientific Advisor and PhD.
Results
The study identified 601 NSCLC patients, with 64 percent tested for genetic alterations.
Among them, 9 percent had the KRAS G12C mutation, with younger age and a smoking history being common characteristics.
Patients with KRAS mutations often presented with metastatic disease at diagnosis, suggesting a more aggressive disease course.
Moreover, patients with KRAS G12C mutation experienced shorter overall survival and higher healthcare resource utilisation compared to other subgroups.
Riikka joined Medaffcon in February 2021. She has a wide-ranging experience from different therapy areas from atherosclerosis and birth asphyxia to neurodegeneration. She has more than 15 years of experience in research, three of which in Max Planck Institute in Germany. Her PhD thesis from 2011 focused on cholesterol metabolism.
Riikka’s strenghts include broad know-how and interest in diverse therapy areas, as well as enthusiasm and experience in both written and verbal scientific communication. At Medaffcon she enjoys varied projects and effectiveness of research.
Real world evidence fascinates Riikka because there is so much data, and more accumulating all the time, and most of this data is unused. There is potential for findings to support clinicians and the pharmaceutical industry, as well as alleviate the lives of patients. She is also happy that decisions in health care are increasingly evidence based.
Samuli joined Medaffcon in November 2018. He acquired a master’s degree in Statistics at the University of Helsinki, specializing in Bioinformatics in September 2018. Before joining Medaffcon, Samuli had two years’ worth of experience in research as a research assistant at the University of Helsinki, where he contributed to unraveling the genetic and epigenetic background of psychological characteristics (Depsy-group).
Samuli is especially interested in producing influential research data based on information on real-world patients. He is also interested in applying varying statistical and machine learning methods. Samuli has a broad theoretical and methodological understanding, as well as experience in working with big data. He is a problem solver and has an analytical take on work.
“I see that the health sector is being transformed by digitalization. I am excited to further develop the new opportunities made possible by the automated collection of patient data”.
Anna joined Medaffcon’s analytics team in the fall of 2021. She has a master’s degree in Bioinformation Technology from Aalto University, and her studies focused primarily on mathematical modeling and machine learning. She has worked at Aalto University’s Department of Neuroscience and Biomedical Engineering as a research assistant, as a teacher in a mathematical modeling course, and in the last years before Medaffcon as a data scientist in a startup developing a medical device.
Anna has a strong background in the application of statistics and especially machine learning methods to various datasets. Anna also has experience in conducting research, all the way from collecting data to analyzing the results and scientific writing. She is particularly interested in solving real-world problems faced by healthcare and medicine using mathematical modeling methods and artificial intelligence.
“The constantly increasing amount of health data, combined with the modern computational capacity and evolving modeling methods, create enormous potential for findings that could hardly be detected by purely manual examination.”
