Clinical and Genomic Features of Androgen Indifferent Prostate Cancer.

Androgen-indifferent prostate cancer (AIPC) is increasingly common and particularly lethal. Data describing these tumors are sparse, and AIPC remains a poorly understood malignancy. Utilizing the Oncology Research Information Exchange Network (ORIEN) database, we enriched for tumors with features of AIPC using previously described characteristics.

Impact of DPP4 Inhibition on Survival in Patients With Metastatic Renal Cell Carcinoma and Type 2 Diabetes Mellitus.

Background: Dipeptidyl peptidase IV (DPP4) is a cell surface receptor that possesses numerous substrates implicated in tumor growth and metastasis. Prior studies have suggested an association between DPP4 inhibition and increased progression-free survival (PFS) and overall survival (OS) in colorectal and lung cancers but no benefit in breast or pancreatic cancers. However, no studies to date have explored the impact of DPP4 inhibitors (DPP4i) in patients with metastatic renal cell carcinoma (mRCC).

Outcomes of Patients with Myeloid Malignancies and Cardiovascular Disease Undergoing Allogeneic Stem Cell Transplantation.

Introduction/background: Reduced-intensity conditioning (RIC) and nonmyeloablative (NMA) regimens have enabled patients with cardiovascular disease (CVD) to undergo allogeneic stem cell transplantation (allo-HSCT). However, little is known about long-term outcomes, including cardiovascular (CV) complications.

Methods: We retrospectively studied 99 consecutive patients with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) who underwent allo-HSCT between September 1, 2013, and November 30, 2020.

Impact of Angiotensin Converting Enzyme Inhibitors on Pathologic Complete Response With Neoadjuvant Chemotherapy for Muscle Invasive Bladder Cancer.

Introduction: The renin-angiotensin system (RAS) has been demonstrated to modulate cell proliferation, desmoplasia, angiogenesis and immunosuppression. We examined the association of RAS inhibitors (RASi)-namely angiotensin converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARB)-with neoadjuvant chemotherapy (NAC) for muscle-invasive bladder cancer (MIBC) preceding radical cystectomy (RC).

Patients And Methods: We retrospectively investigated concurrent RASi use with NAC prior to RC in 302 patients with MIBC from 3 academic institutions.

Frontline Blinatumomab in Older Adults with Philadelphia Chromosome-Negative B-Cell Acute Lymphoblastic Leukemia.

Outcomes of acute lymphoblastic leukemia (ALL) in older adults treated with chemotherapy are poor. The CD19/CD3 bispecific T-cell engager (BiTE) antibody blinatumomab is approved for refractory, relapsed or minimal/measurable residual disease (MRD)-positive B-cell ALL, but there is little experience in the upfront setting, including in older patients. We retrospectively analyzed outcomes of blinatumomab monotherapy in five newly diagnosed Philadelphia chromosome-negative B-cell ALL patients over 70 years.

Active Tuberculosis Case Finding in Haiti.

In 2010, Haiti suffered from a devastating earthquake; data on the impact on the tuberculosis (TB) epidemic are limited. From January to June 2013, we conducted active case finding at the household level in a slum in Port-au-Prince. Community health workers identified individuals with cough ≥ 2 weeks, and referred them for evaluation.

Safe and effective sofosbuvir-based therapy in patients with mental health disease on hepatitis C virus treatment.

Aim: To study impact of baseline mental health disease on hepatitis C virus (HCV) treatment; and Beck's Depression Inventory (BDI) changes with sofosbuvir- and interferon-based therapy.

Methods: This is a retrospective cohort study of participants from 5 studies enrolled from single center trials conducted at the Clinical Research Center of the National Institutes of Health, Bethesda, MD, United States. All participants were adults with chronic HCV genotype 1 infection and naïve to HCV therapy.
