Neoantigen-specific CD4+ T cells induce protective, tumor-specific CD8+ T cells in a mouse model of multiple myeloma.

Cancer immunotherapies have primarily focused on generating tumoricidal CD8 T cells. However, recent data demonstrate a critical role for CD4 T cells in tumor immunity. CD4 T cells against epitopes derived from mutated tumor-associated neo-antigens (neoAg) conferred protection against tumor growth in animal models of neoAg vaccine therapy. In clinical studies, immunity elicited by neoAg vaccines was associated with improved survival, even though the majority of immune responses were CD4 T cells that did not have cytolytic activity.

Chimeric antigen receptor (CAR)-T cell therapy is a new and powerful class of cancer immunotherapy [1,2]. Clinical trials of CAR-T cell therapy targeting the B-cell marker CD19 have shown promising results for the treatment of hematologic malignancies, including acute lymphoblastic leukemia (ALL) [3 –7], chronic lymphocytic leukemia (CLL) [8,9], and non-Hodgkin lymphoma (NHL) [10,11]. CAR-T cell therapy targeting B-cell maturation antigen (BCMA) has also been demonstrated to be effective for treating multiple myeloma (MM) [12–15].

CONCLUSIONS: Although our meta-analysis showed statistically significant increased risks of either cancer incidence or mortality of certain cancers in association with firefighting, a number of important limitations of the underlying studies exist, which, precluded our ability to arrive at definitive conclusions regarding causation.

Shutdowns earlier this year of two facilities that use ethylene oxide (EtO) to sterilize medical devices prompted FDA to monitor for supply shortages in the industry because EtO is such a popular sterilization method for medical devices. This week the agency revealed steps it will take to reduce medtech's reliance on EtO sterilization. EtO is a flammable, colorless gas used to sterilize equipment and plastic devices that cannot be sterilized by steam, such as medical equipment. In fact, about half of all sterilized medical devices undergo sterilization using this gas. Breathi...

Publication date: Available online 22 November 2019Source: Journal of Geriatric OncologyAuthor(s): Reena Jayani, Ashley Rosko, Rebecca Olin, Andrew ArtzAbstractHematopoietic cell transplant (HCT) is an important aspect of treatment for many hematologic malignancies. As cancer is a disease associated with aging, and hematologic malignancies are no exception, rates of autologous and allogeneic HCT utilization in older adults are on the rise. The most common indications for autologous HCT are multiple myeloma and lymphoma, and for allogenic HCT are acute myeloid leukemia and myelodysplastic syndrome. Older adults into their e...

This study aimed to determine the impact of treatment facility on overall survival outcomes in DLBCL patients stratified by IPI risk groups.MethodsThe National Cancer Database was utilized to identify patients diagnosed with DLBCL between 2004 and 2015. Patients were stratified by IPI risk score from low to high risk disease, and overall survival of those treated at academic centers were compared to those treated at non-academic centers.ResultsTreatment at academic centers was associated with a significantly improved overall survival for all DLBCL patients (108.3 months) when compared to non-academic centers (74.5 months, p

Conclusions: Patients with IPF had a higher risk for various types of cancer incidence compared to matched control cohort. Greater attention should be paid to cancer development and screening in patients with IPF.

ConclusionsPCPs report several barriers in providing care to hematologic malignancy/HCT survivors. Clinical experience with this patient population is associated with greater confidence in providing survivorship care. Several barriers identified by PCPs in providing survivorship care to hematologic malignancy/HCT survivors are potentially addressable by education, clinical decision support tools and guidelines, enhancing clinical experience, and care coordination with hematologist-oncologists.

We describe three clinical scenarios in which CAR T- cell immunotherapy interfered with HIV-1 testing including: (1) routine infectious disease screening prior to stem cell transplantation in a 16-year-old female with B-cell acute lymphoblastic leukemia, status post CAR T- cell treatment (2) routine infectious disease screening prior to 2nd CAR T- cell collection in a 65-year-old male with diffuse large B-cell lymphoma who failed initial CAR T- cell treatment and (3) routine infectious risk assessment following an occupational health exposure from a 58 -year-old male with multiple myeloma, status post CAR T- cell treatment...

Kim De Veirman AXL belongs to the TAM (TYRO3, AXL, and MERTK) receptor family, a unique subfamily of the receptor tyrosine kinases. Their common ligand is growth arrest-specific protein 6 (GAS6). The GAS6/TAM signaling pathway regulates many important cell processes and plays an essential role in immunity, hemostasis, and erythropoiesis. In cancer, AXL overexpression and activation has been associated with cell proliferation, chemotherapy resistance, tumor angiogenesis, invasion, and metastasis; and has been correlated with a poor prognosis. In hematological malignancies, the expression and function of AXL is highly...
