Addressing the Challenges of Novel Oncology and Hematology Treatments Across Sites of Care: Specialty Pharmacy Solutions.

Background: The number of Food and Drug Administration (FDA) approvals for anticancer therapies has significantly increased in recent years, but these novel therapies are costly and present challenges to patients and providers. Many institutions have implemented health systems specialty pharmacies (HSSPs) to help patients and providers navigate financial and logistical barriers to treatment with oral anticancer therapies. Patients on oral anticancer therapy are often treated across multiple sites of care which can complicate the inpatient specialty medication initiation process. Health systems often limit inclusion of oral anticancer therapies for inpatient administration due to costs, however several new therapies necessitate admission for treatment initiation. Health systems are then faced with the challenge of starting costly oral anticancer therapy inpatient and ensuring continued access to therapy upon discharge. We describe the integrated HSSP multidisciplinary approach to this MUP including providers, inpatient and outpatient pharmacists, specialty and inpatient pharmacies, institutional procurement team, and the institutional pharmacy and therapeutics (P&T) committee to streamline this process.The HSSP multidisciplinary processes addresses a growing need for cancer patients to receive timely and affordable treatments across different sites of care. The healthcare team and P&T committee ensure the patient receives the most appropriate therapy while being conscious of health-system costs. The HSSP and procurement team ensure the patient can obtain and afford the medication. The implemented processes allows for direct communication and collaboration between different sites of care and this collaborative approach leads to optimal patient care.

The Colorectal Cancer Tumor Microenvironment and Its Impact on Liver and Lung Metastasis.

Colorectal cancer (CRC) is the third most common malignancy and the second most common cause of cancer-related mortality worldwide. A total of 20% of CRC patients present with distant metastases, most frequently to the liver and lung. In the primary tumor, as well as at each metastatic site, the cellular components of the tumor microenvironment (TME) contribute to tumor engraftment and metastasis. These include immune cells (macrophages, neutrophils, T lymphocytes, and dendritic cells) and stromal cells (cancer-associated fibroblasts and endothelial cells). In this review, we highlight how the TME influences tumor progression and invasion at the primary site and its function in fostering metastatic niches in the liver and lungs. We also discuss emerging clinical strategies to target the CRC TME.

Macrophages: The Road Less Traveled, Changing Anticancer Therapy.

Macrophages are present in all vertebrate tissues and have emerged as multifarious cells with complex roles in development, tissue homeostasis, and disease. Macrophages are a major constituent of the tumor microenvironment, where they either promote or inhibit tumorigenesis and metastasis depending on their state. Successful preclinical strategies to target macrophages for anticancer therapy are now being evaluated in the clinic and provide proof of concept that targeting macrophages may enhance current therapies; however, clinical success has been limited. This review discusses the promise of targeting macrophages for anticancer therapy, yet highlights how much is unknown regarding their ontogeny, regulation, and tissue-specific diversity. Further work might identify subsets of macrophages within different tissues, which could reveal novel therapeutic opportunities for anticancer therapy.
