Operationalizing Next-Generation Sequencing in a Community-Based Academic Cancer Center: Workflow, Integration, and Impact

Le résumé fourni par la source

Background/Objectives: Prompt integration of molecular and clinical data into electronic medical records, with a sustainable workflow that supports clinicians in rendering genomics-guided care, is critical. We sought to expand the implementation of in-house NGS at our community-based academic cancer center to operationalize the utilization of molecular diagnostic studies to optimize cancer care for all patients, including those outside this study, through broader adoption and diffusion. Methods: In this prospective IRB-approved study, the Kellogg Cancer Genomic Initiative (KCGI), patients with advanced cancers underwent in-house NGS, including tumor mutational burden (TMB) and pharmacogenomics. In-house bioinformatics (Flype) was used for structured reporting and served as a molecular knowledgebase. A multidisciplinary molecular tumor board (MTB) was created to provide precision therapy recommendations. Results: In-house NGS, completed within 11 business days on average, was performed in 90% (251) of the 279 patients in the KCGI with advanced cancers. RNA and TMB analyses were successful in 89.2% and 86.5% of patients, respectively. A total of 54.2% of patients were identified as candidates for use of on- or off-label FDA-approved therapies, and 99.6% of patients who underwent pharmacogenomics testing had at least one gene alteration associated with medication dose adjustment/avoidance. An MTB was established to discuss these and other molecularly challenging cases continues to function as a consultative service that provides actionable recommendations. Conclusions: In this real-world trial, the utilization of in-house NGS with an adaptable bioinformatics pipeline and the establishment of an MTB enabled the refinement of institutional processes and created an environment that enhanced clinician interest in genomics and improved genomics-guided care for patients with advanced cancers.
