Article Synopsis
  • BAP1 mutations lead to a loss of function affecting cell cycle and DNA repair, making patients potentially responsive to PARP inhibitors like niraparib.
  • A phase II trial evaluated niraparib in patients with advanced tumors likely to have mBAP1 mutations, focusing on response rates, progression-free survival, and overall survival.
  • Despite not meeting the primary efficacy goal, some clinical benefits were observed in patients with confirmed mBAP1 mutations, suggesting the need for further research.

The University of Florida Health conducted a pragmatic implementation of a pharmacogenetics (PGx) panel-based test to guide medications used for supportive care prescribed to patients undergoing chemotherapy. The implementation was in the context of a pragmatic clinical trial for patients with non-hematologic cancers being treated with chemotherapy. Patients were randomized to either the intervention arm or control arm and received PGx testing immediately or at the end of the study, respectively.

For patients with localized pancreatic cancer with minimal vascular involvement, optimal survivability requires a multidisciplinary approach of surgical resection and systemic chemotherapy. FOLFIRINOX is a combination chemotherapy regimen that offers promising results in the perioperative and metastatic settings; however, it can cause significant adverse effects. Such toxicity can negatively impact some patients, resulting in chemotherapy discontinuation or surgical unsuitability.

Background Anthracyclines remain a key treatment for many malignancies but can increase the risk of heart failure or cardiomyopathy. Specific guidelines recommend echocardiography and serum cardiac biomarkers such as BNP (B-type natriuretic peptide) or NT-proBNP (N-terminal proBNP) evaluation before and 6 to 12 months after treatment. Our objective was to evaluate associations between racial and ethnic groups in cardiac surveillance of survivors of cancer after exposure to anthracyclines.

There is surmounting levels of evidence on the health disparities within cancer treatment in the United States (US). Most of the research focused on cancer specific factors including anticancer incidence, screening, treatment and follow-up, and clinical outcomes such as overall survival (OS). Less is known about the disparities present with supportive care medication use in cancer patients.

Pancreatic ductal adenocarcinoma (PDAC) is currently the third leading cause of cancer mortality and the incidence is projected to increase by 2030. Despite recent advances in its treatment, African Americans have a 50-60% higher incidence and 30% higher mortality rate when compared to European Americans possibly resulting from differences in socioeconomic status, access to healthcare, and genetics. Genetics plays a role in cancer predisposition, response to cancer therapeutics (pharmacogenetics), and in tumor behavior, making some genes targets for oncologic therapeutics.

Immune checkpoint inhibitor therapy represents a significant advance in cancer care. The interaction between PD-1 and PD-L1 induces immune tolerance and the inhibition of this interaction is an effective treatment strategy for numerous malignancies. Despite its demonstrated potential, immunotherapy is not clinically effective in immunogenically 'cold' tumors such as pancreatic cancer, prostate cancer and neuroendocrine tumors.

As cancer treatment evolves in the era of precision oncology, molecularly targeted agents (MTAs) have become frontline therapy for many cancers. MTAs are biologically targeted and thought to have less off-target toxicity; however, the eye is particularly susceptible to off-target toxicities given its unique microenvironment. In this review, we present commonly used FDA-approved MTAs, any associated ocular toxicities and review the mechanisms, frequency, severity, and management.

Multiple myeloma (MM) is the second most frequent hematologic cancer in the United States. Carfilzomib (CFZ), an irreversible proteasome inhibitor being used to treat relapsed and refractory MM, has been associated with cardiotoxicity, including heart failure. We hypothesized that a multi-omics approach integrating data from different omics would provide insights into the mechanisms of CFZ-related cardiovascular adverse events (CVAEs).

Background: Immune checkpoint inhibitors (ICIs) are a novel class of anticancer agents that have demonstrated clinical response for both solid and hematological malignancies. ICIs are associated with development of immune-related adverse events including cardiotoxicity. We estimated the incidence of newly diagnosed cardiovascular disease in patients treated with ICIs at a large, tertiary care center.

To develop, implement, and assess student performance and confidence in a pharmacy capstone course that used case-based instruction and the Pharmacist's Patient Care Process (PPCP) to develop patient work-up skills in third-year Doctor of Pharmacy (PharmD) students. A skills-based capstone course was developed by a team of faculty members and instructional designers that focused on patient evaluation skills and applying the steps of the PPCP to complex patient cases housed in a simulated electronic health record (SEHR). The acuity of the cases increased over the course of the semester.
