Case report of a HER2-expressed ovarian clear cell carcinoma with exceptional response to trastuzumab deruxtecan.

Electronic Health Records and Genomics: Perspectives from the Association for Molecular Pathology Electronic Health Record (EHR) Interoperability for Clinical Genomics Data Working Group.

The use of genomics in medicine is expanding rapidly, but information systems are lagging in their ability to support genomic workflows both from the laboratory and patient-facing provider perspective. The complexity of genomic data, the lack of needed data standards, and lack of genomic fluency and functionality as well as several other factors have contributed to the gaps between genomic data generation, interoperability, and utilization. These gaps are posing significant challenges to laboratory and pathology professionals, clinicians, and patients in the ability to generate, communicate, consume, and use genomic test results. The Association for Molecular Pathology Electronic Health Record Working Group was convened to assess the challenges and opportunities and to recommend solutions on ways to resolve current problems associated with the display and use of genomic data in electronic health records.

Evaluation of Radioactivity in Patient Specimens Received in the Core Laboratory at a National Cancer Institute (NCI) Designated Cancer Center.

BACKGROUND: Biological specimens from patients who have received radiopharmaceuticals are often collected for diagnostic testing and sent to clinical laboratories. Residual radiation has long been assumed to be minimal. However, literature is sparse and may not represent the specimen volumes or spectrum of radionuclides currently seen at National Cancer Institute (NCI)-designated cancer centers. This study examined the radiopharmaceuticals associated with patient specimens received in the hospital core laboratory and assessed the potential risk of external radiation exposure to laboratory personnel. METHODS: The types and amounts of radiopharmaceuticals administered in a large metropolitan hospital system were retrospectively examined over a 20-month study period. The associated biological specimens sent to the largest core laboratory in the system for testing were evaluated. In addition, manual survey meter assessment of random clinical specimens and weekly wipe tests were performed for 44 weeks, and wearable and environmental dosimeters were placed for 6 months. RESULTS: Over 11 000 specimens, collected within 5 physical half-lives of radiopharmaceutical administration, were processed by our laboratory. Manual survey meter assessment of random clinical specimens routinely identified radioactive specimens. If held in a closed palm for >2 min, many samples could potentially deliver a 0.02 mSv effective dose of radiation. CONCLUSIONS: The laboratory regularly receives radioactive patient specimens without radioactive labels. Although the vast majority of these are blood specimens associated with low-dose diagnostic radiopharmaceuticals, some samples may be capable of delivering a significant amount of radiation. Recommendations for laboratories associated with NCI cancer centers are given.
