MA21.07 - A Nation-Wide Population-Based Mapping of Targetable Alterations in Smoking-Independent Lung Cancer (ID 13145)
15:55 - 16:00 | Author(s): Eva Brandén
Smoking is by far the most important cause of lung cancer. However, lung cancer among never-smokers is common and increasing . A smoking-independent subgroup of lung adenocarcinoma with certain molecular and clinical features exists [2-3]. Therefore, as 1st project within the Swedish Molecular Initiative against Lung cancer (SMIL) we aim to characterize never-smoking lung cancer for etiological, diagnostic and therapeutic purposes.a9ded1e5ce5d75814730bb4caaf49419 Method
Through the Swedish National Lung Cancer Registry , we identified all individuals who underwent surgery for lung cancer in Sweden 2005-2014 and who were registered as never-smokers (n=540). At each study site (n=6), clinical data were reviewed by a thoracic oncologist/pulmonologist through patients’ medical charts and archived tumor tissues were retrieved and reviewed by a thoracic pathologist. For subsequent studies, we extracted DNA and RNA (using the Qiagen AllPrep kit for FFPE tissue) and constructed tissue microarrays. As a first pre-planned analysis, we performed fusion gene mapping using an RNA-based NanoString nCounter Elements assay, as previously described .4c3880bb027f159e801041b1021e88e8 Result
In the first 212 (out of 540) analyzed samples, we detected 17 fusions involving ALK, 8 involving RET, and 2 involving NRG1. In addition, MET exon 14 skipping was found in 17 samples. In total, these findings involved 21% of analyzed cases. Additional results from further studies on the cohort will be presented.8eea62084ca7e541d918e823422bd82e Conclusion
SMIL is an ongoing nation-wide molecular research collaboration on lung cancer where we currently collect one of the largest never-smoking lung tumor cohorts worldwide. From the first pre-planned analyses, we conclude that, in a population-based cohort of early stage lung cancer from never-smokers, druggable oncogenic fusions are frequent.

P2.01-59 - The Cost of Lung Cancer in the County of Gävleborg – Sweden (ID 14423)
16:45 - 18:00 | Author(s): Eva Brandén
Lung cancer is the leading cause of cancer morbidity and mortality, both of which imply that its burden may be high upon the health services and society. The purpose of this study is to present an economic analysis of the actual care costs of lung cancer which will allow comparison with, and verification of, cost estimates that were developed through modelling and opinion.a9ded1e5ce5d75814730bb4caaf49419 Method
A chart review was conducted of incident cases of all patients with newly diagnosed lung cancer during 2015 in the Department of Respiratory Medicine, Gävle Hospital. Cases were censored at two years from the date of diagnosis. Data was retrospectively collected from patient charts. This data included patient characteristics, tumour characteristics, treatment details, adverse events, survival and resource use. Relevant clinical and health utilization data were collected. Health utilization data included hospital and institutional outpatient (ie, ambulatory clinic) costs. The present analysis was performed from the economic perspective of the health care institution.4c3880bb027f159e801041b1021e88e8 Result
A total of more than 13 000 health service events were captured. Laboratory tests, diagnostic imaging and ambulatory visits constituted 86% of the service events while patient admissions and therapy constituted 76% of the costs. The vast majority of overall costs occurred just before, or within, three months of diagnosis. The cost for imaging was 344042 USD and for diagnostic procedures was 204272 USD. The total cost for chemotherapy was 651879 USD.
More data will be presented during the conference.8eea62084ca7e541d918e823422bd82e Conclusion
The results agree with the literature that the majority of lung cancer case costs are realized around the date of diagnosis (ie, early phase). The present study illustrates Swedish health care system lung cancer case costs based on actual care received .The majority of the costs occurred soon after diagnosis. These results gave an assessment of all persons treated, the course of the treatment and, thus, is an accurate assessment of costs for policy-making purposes.6f8b794f3246b0c1e1780bb4d4d5dc53
