Budget impact analysis of next-generation sequencing versus sequential single-gene testing in Japanese patients with advanced non-small-cell lung cancer.

BACKGROUND: Identification of genomic alterations (e.g., EGFR, ALK, ROS1, BRAF, NTRK, and MET) is essential for initiating targeted therapy in patients with advanced non-small-cell lung cancer (aNSCLC). This study estimated the budget impact of using the sequential single-gene (SSG) test, which tests for each mutation one at a time, versus next-generation sequencing (NGS), which tests for all mutations at the same time, among newly diagnosed patients with aNSCLC from a Japanese healthcare payer's perspective. METHODS: A budget impact model (BIM) was used to determine the expected budget impact associated with NGS for newly diagnosed aNSCLC in Japan over a 3-year period. The BIM compared the total costs (biopsy, testing, and treatment) and average turnaround time of "future NGS" and "current NGS" versus SSG testing. RESULTS: The adoption of current NGS over SSG testing had a budget impact of -0.24%, but adoption of future NGS over SSG testing had a budget impact of +4.33% across a 3-year time horizon on the Japanese budget for aNSCLC treatment. The adoption of current or future NGS over SSG testing would shorten the average turnaround time for testing. CONCLUSIONS: The adoption of current NGS over SSG testing would slightly decrease the yearly costs. However, the adoption of future or current NGS over SSG testing would shorten the average turnaround time, enabling faster identification of genomic alterations and earlier initiation of treatment for aNSCLC patients in Japan.

Assessment of bleeding in patients with disseminated intravascular coagulation after receiving surgery and recombinant human soluble thrombomodulin: A cohort study using a database.

We aimed to investigate the incidence of bleeding-related adverse events (AEs) among patients with disseminated intravascular coagulation (DIC) receiving recombinant thrombomodulin (rTM) and those receiving other DIC treatments, the incidence by type of surgery, and the incidence when either blood transfusion or a hemostatic procedure was administered to treat DIC. In this cohort study, data were obtained from a large medical database (22 centers in Japan). The primary endpoint was the incidence rate of bleeding-related AEs by type of surgery. The secondary endpoint was the incidence rate of bleeding-related AEs based on whether blood transfusion or a hemostatic procedure was administered after the day of DIC treatment. In total, 4234 propensity score-matched patients were included in the main analysis (2117 patients each in the rTM and non-rTM groups). In the rTM and non-rTM groups, respectively, the incidence of bleeding-related AEs was 18.8% and 24.8% (p <0.001; risk ratio [RR] 0.757, 95% confidence interval [CI] 0.674-0.849), among patients requiring any type of surgery; 15.0% and 19.5% (p = 0.0001; RR 0.769, 95% CI 0.673-0.879) in patients requiring blood transfusion or a hemostatic procedure after the day of DIC treatment; 10.2% and 11.6% (p = 0.4470; RR 0.879, 95% CI 0.630-1.226) in patients undergoing hepatic, biliary, or pancreatic surgery; 24.3% and 25.4% (p = 0.6439; RR 0.955, 95% CI 0.786-1.160) in patients undergoing gastrointestinal surgeries; and 18.5% and 30.1% (p = 0.0001; RR 0.614, 95% CI 0.481-0.782) in patients undergoing cardiac or cardiovascular surgery. Our findings suggest that rTM treatment for Japanese postsurgical patients who develop DIC was associated with significantly fewer bleeding-related AEs compared with those receiving other DIC treatments.
