Importance: Clonal hematopoiesis (CH) has been associated with development of atherosclerosis and leukemia and worse survival among patients with cancer; however, the association with cancer therapy efficacy, in particular immune checkpoint blockade (ICB), and toxicity has not yet been established. Given the widespread use of ICB and the critical role hematopoietic stem cell-derived lymphocytes play in mediating antitumor responses, CH may be associated with therapeutic efficacy and hematologic toxicity.
Objective: To determine the association between CH and outcomes, hematologic toxicity, and therapeutic efficacy in patients with metastatic gastrointestinal tract cancers being treated with systemic therapy, both in the first-line metastatic treatment setting and in ICB.
Background: Patients with germline/somatic BRCA1/BRCA2 mutations (g/sBRCA1/2) comprise a distinct biologic subgroup of pancreas ductal adenocarcinoma (PDAC).
Methods: Institutional databases were queried to identify patients who had PDAC with g/sBRCA1/2. Demographics, clinicopathologic details, genomic data (annotation sBRCA1/2 according to a precision oncology knowledge base for somatic mutations), zygosity, and outcomes were abstracted.
A 64-year-old man with anal cancer underwent follow-up F-FDG PET/CT to evaluate chemoradiation therapy response 5 months after an initial PET/CT. The follow-up F-FDG PET/CT demonstrated new FDG-avid curvilinear soft tissue adjacent to the abdominal aorta, interpreted as an aortic dissection. Despite lack of clinical symptoms, the patient was directed to an emergency room the same day, where a contrast-enhanced CT confirmed an aortic aneurysm with dissection.

Regorafenib is a multikinase inhibitor targeting angiogenic and stromal receptor tyrosine kinases. We evaluated whether regorafenib augments the antitumor effect of first-line chemotherapy in metastatic esophagogastric cancer.

Therapeutic resistance is likely mediated in part by co-occurring amplifications of the genes for multiple oncogenic receptor tyrosine kinases (RTK). We therefore tested the efficacy of combined inhibition of VEGFR1-3, PDGFα/β, and FGFR1-3 using nintedanib.

For women with SUD trying to reclaim sobriety and a healthy life, family can present both barriers and support. The aim of this study is to gain a deeper understanding of the intersection of family relationships with motivation of women in Drug Treatment Court (DTC) to attain their health goals.

We examined the efficacy and safety of modified docetaxel, cisplatin and 5 fluorouracil (mDCF) plus trastuzumab in a single-arm multicenter phase II trial.
Methods: Previously untreated patients with HER2-positive metastatic gastric or GE junction adenocarcinoma were treated with mDCF and trastuzumab every 2 weeks.
