The concentration of short, but not long, cfDNA fragments increased postoperatively. Of 25 patients with radiological relapse, eight were ctDNA-positive and 17 were ctDNA-negative in the period with trauma-induced DNA. Analysis of longitudinal samples revealed that five of the negative patients became positive shortly after the release of trauma-induced cfDNA had ceased. In conclusion, surgery was associated with elevated cfDNA levels, persisting up to 4 weeks, which may have masked ctDNA in relapse patients. Trauma-induced cfDNA was of similar size to ordinary cfDNA. To mitigate the impact of trauma-induced cfDNA on ctDNA detection, it is recommended that a second blood sample collected after week 4 is analyzed for patients initially ctDNA negative.Aims/introduction There is uncertainty about the direct medical costs of type 2 diabetes mellitus (T2DM) patients with cancers. Materials and methods A population-based retrospective cohort of 99915 T2DM patients from Hong Kong Hospital Authority between 2006 and 2017 was assembled. 16869 patients who had initial cancer diagnosis after T2DM were matched with 83046 patients without cancer (controls) using a matching ratio up to one-to-five propensity score-matching method. Patients were divided into four categories according to life expectancy. Healthcare service utilization and direct medical costs during the index year, subsequent years, and mortality year were compared between patients with and without cancer in each category. Results Medical costs of cancer patients in index year ranged from US$27533 for patients died 90% of the medical costs for both groups in mortality year. Conclusions T2DM patients with cancers incurred greater medical costs in the diagnosis, ensuing, and mortality years than T2DM patients without cancers
