Abstract

Introduction Lung cancer is a leading cause of cancer mortality worldwide. Non-invasively collected biofluids such as exhaled breath condensate (EBC) present a potential sampling medium to detect and study pathological changes implicated in tumourigenesis. Mitochondrial DNA changes have been implicated in the carcinogenesis process. Consequently, the detection of mitochondrial changes in EBC could expand our understanding of lung carcinogenesis as well as identifying specific markers for future studies.Methods EBC and saliva was collected from newly diagnosed subjects with lung cancer and control subjects in a cross-sectional study. The EBC and saliva was analysed for mitochondrial DNA D-loop changes using a PCR sequencing approach. The sequences obtained were compared to paired salivary DNA and the revised Cambridge Reference Sequence (rCRS) to identify somatic mutations, and quantitative and qualitative differences in mutations were analysed between groups.Results A total of 25 subjects (9 NSCLC patients, 10 smokers/ex-smokers and 6 non-smokers) were recruited. A significantly elevated D-loop mutation rate in the lung cancer group compared to the control groups was present (7 vs 3.5 for smokers/ex-smokers, and 7 vs. 4 for non-smokers, p = 0.034). The recognised mutation T16217C showed specificity for lung cancer.Conclusions Mitochondrial DNA mutations are more common in the EBC of patients with lung cancer. This suggests that these processes are associated with the carcinogenesis of lung cancer and may be a marker of the disease.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
