Epcoritamab and glofitamab are CD20-directed bispecific antibodies approved in the US for relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL). Limited data exist for patients treated outside of trials. Patients with R/R DLBCL receiving commercial epcoritamab or glofitamab between January 1, 2023 and October 15, 2024 were collected from 21 US institutions.

Although adjuvant endocrine therapy (ET) greatly lowers the risk of recurrence and mortality in hormone receptor (HR)-positive early-stage breast cancer (EBC), more than 20% of patients may experience relapses within 10 years, often manifesting as incurable distant metastases. To improve outcomes, ovarian function suppression (OFS) with gonadotropin-releasing hormone agonists (GnRHa) added to tamoxifen or aromatase inhibitors like exemestane have shown significant disease-free survival (DFS) and, in some cases, overall survival (OS) benefits. CDK4/6 inhibitors, a cornerstone in metastatic HR-positive, HER2-negative breast cancer (MBC), are now being explored in EBC.

Introduction: Pancreatic ductal adenocarcinoma (PDAC) remains a highly lethal malignancy with limited therapeutic options and poor overall survival. In recent years, advances in genomic profiling have revealed the complex molecular and cellular heterogeneity of PDAC, offering new avenues for therapeutic intervention.

Areas Covered: This review explores emerging therapeutic strategies targeting dysregulated molecular pathways, along with the tumor microenvironment, that have shown promise in overcoming drug resistance.

Article Synopsis
  • - VEXAS syndrome is a rare, inherited inflammatory disease that usually appears in adults around their 50s and requires treatments such as allogeneic hematopoietic cell transplantation (allo-HCT) for severe cases.
  • - A systematic review/meta-analysis of 88 studies was conducted, revealing that among 39 patients included, the overall survival rate after allo-HCT was 86%, while the event-free survival rate was 56%.
  • - While allo-HCT is shown to be an effective treatment, it also carries risks, with a 14% non-relapse mortality rate and rates of acute and chronic graft-versus-host disease at 42% and 13%, respectively.

Background And Objectives: Almost 25% of patients with lymphoma may have relapse or develop refractory disease, and a majority of such patients undergo salvage chemotherapy and autologous stem cell transplantation (ASCT). Data on venous thromboembolism (VTE) in this setting are scarce. This study aimed to investigate the prevalence and factors that may increase the risk of VTE in such patients.

Background: Ectopic Cushing syndrome (EAS) secondary to an adrenocorticotropin hormone (ACTH)-releasing neuroendocrine tumor (NET) is a rare diagnosis that can be resistant to standard treatments. Abiraterone acetate (AA) is a selective and irreversible inhibitor of 17α-hydroxylase/17,20-lyase that blocks adrenal steroidogenesis, including cortisol synthesis. In this case, we present the novel use of AA in treating malignant EAS by blocking cortisol synthesis.

Breast cancer is the most common cancer diagnosed among women worldwide and more than half are diagnosed above the age of 60 years. Life expectancy is increasing and the number of breast cancer cases diagnosed among older women are expected to increase. Undertreatment, mostly due to unjustifiable fears of advanced-age and associated comorbidities, is commonly practiced in this group of patients who are under-represented in clinical trials and their management is not properly addressed in clinical practice guidelines.

Article Synopsis
  • Breast cancer frequently metastasizes to bones, and the differences between those with de novo bone-only metastasis (BOM) compared to those who progress from early-stage disease remain unclear.
  • A retrospective study of 242 breast cancer patients revealed that most had de novo BOM, with significantly shorter overall survival (40.8 months) compared to those who developed BOM later (80.9 months).
  • Factors like tumor grade, hormone receptor status, and lesion type were found to significantly affect survival outcomes, highlighting the need for tailored treatment approaches.

Background: Cyclin-dependent kinase (CDK) 4/6 inhibitors have revolutionized the treatment landscape of hormone receptor-positive (HR), human epidermal growth factor receptor 2-negative (HER2) metastatic breast cancer, with an impressive efficacy and safety profile. Cytopenia is the main adverse event, which is both predictable and manageable. Here, we report a case of CDK4/6 inhibitor-induced vitiligo-like lesions.

Everolimus combined with exemestane can modulate endocrine resistance. The combination showed significant improvement in progression-free survival (PFS) in phase III clinical trials for hormone receptor positive metastatic breast cancer patients. It also showed serious adverse events.

Objectives: The crisis in Syria has had a profound impact on the entire region. In this study, we report the patterns of presentation and management of Syrian patients with breast cancer treated at our institution.

Methods: We retrospectively collected data on Syrian refugees treated for breast cancer over the past 10 years at our center.

Purpose: In developing countries, a higher percentage of patients develop cancer at a younger age. Cancer survival rates have significantly improved, highlighting the importance of survivorship programs that address late complications related to cancer itself or its treatment. The purpose of this study is to estimate the prevalence of fertility counseling and sperm banking and related factors among at-risk males newly diagnosed with cancer and planning to receive a potentially curative anticancer therapy.

Patients with cancer have an increased risk of venous thromboembolism. Upper extremity venous system is a peculiar site, and little is known about the clinical course in patients with cancer. Electronic medical records were searched for patients with cancer with a diagnosis of upper extremity venous thrombosis.

Background: Vertebroplasty is a minimally invasive procedure commonly performed for vertebral compression fractures secondary to osteoporosis or malignancy. Leakage of bone cement into the paravertebral venous system and cement pulmonary embolism (cPE) are well described, mostly in patients with osteoporosis. Little is known about the clinical sequelae and outcomes in cancer patients.
