While better management of loco-regional prostate cancer (PC) has greatly improved survival, advanced PC remains a major cause of cancer deaths. Identification of novel targetable pathways that contribute to tumor progression in PC could open new therapeutic options. The di-ganglioside GD2 is a target of FDA-approved antibody therapies in neuroblastoma, but the role of GD2 in PC is unexplored.

Overexpression of the EPS15 Homology Domain containing 1 (EHD1) protein has been linked to tumorigenesis but whether its core function as a regulator of intracellular traffic of cell surface receptors plays a role in oncogenesis remains unknown. We establish that EHD1 is overexpressed in Ewing sarcoma (EWS), with high EHD1 mRNA expression specifying shorter patient survival. ShRNA-knockdown and CRISPR-knockout with mouse Ehd1 rescue established a requirement of EHD1 for tumorigenesis and metastasis.

Improved maintenance treatments are needed for patients with relapsed/refractory aggressive lymphomas after autologous haematopoietic stem cell transplantation (ASCT). Several studies with lenalidomide have been found to have activity in the treatment of relapsed/refractory aggressive lymphomas. In the present phase I/II, single-arm, open-label study, 59 patients with high-risk relapsed non-Hodgkin lymphoma received pretransplant BEAM chemotherapy and ASCT followed by 12 months of maintenance lenalidomide once daily on Days 1-21 (28-day cycles) beginning at post-transplantation Day 100.

With nearly all cancer deaths a result of metastasis, elucidating novel pro-metastatic cellular adaptations could provide new therapeutic targets. Here, we show that overexpression of the EPS15-Homology Domain-containing 2 (EHD2) protein in a large subset of breast cancers (BCs), especially the triple-negative (TNBC) and HER2+ subtypes, correlates with shorter patient survival. The mRNAs for EHD2 and Caveolin-1/2, structural components of caveolae, show co-overexpression across breast tumors, predicting shorter survival in basal-like BC.

Background And Purpose: Stereotactic Body Radiotherapy (SBRT) has emerged as a standard treatment for inoperable early-stage non-small cell lung cancer (NSCLC) with remarkable local control. However, it is not clear if this local control translates to overall survival (OS). The objective of this study is to investigate the impact of SBRT on the OS of early-stage NSCLC patients and examine if the extent of this impact changes with the era of diagnosis, T stage, age, and comorbidity status.

Immunotherapy has shown great success in various malignancies. However, its efficacy in pancreatic ductal adenocarcinoma (PDAC) remains a challenge, and the lack of understanding about the appropriate timing of immunotherapy with other standard-of-care cancer treatments may be one of the causes. The objective of the current study is to investigate the impact of the timing of immunotherapy with chemotherapy and radiation therapy (RT) on the overall survival (OS) of PDAC patients who did not receive surgical resection of the pancreatic tumor.

Article Synopsis
  • Cervical cancer is a major health concern for women globally, particularly for those living with HIV, and this study focused on women receiving care at an HIV clinic in Dodoma, Tanzania.
  • The research revealed that while a significant number of women were aware of cervical cancer, many had poor knowledge about it, and a large majority had never been screened; however, most expressed a willingness to undergo screening.
  • The findings highlighted that factors like age, educational level, and urban residence played a crucial role in awareness and willingness to screen, emphasizing the need for enhanced education and integration of cervical cancer services in HIV care.

Objective: Evidence is scant regarding symptom clusters and quality of life (QOL) over 1 year in women who receive adjuvant breast cancer chemotherapy (CTX). Our purpose was to identify the prevalence and severity of individual symptoms, symptom clusters, and QOL in women receiving adjuvant breast cancer CTX from baseline over 1 year.

Methods: Symptoms were identified in a sample ( = 219) at three times: baseline (prior to the first adjuvant CTX treatment), 1 month after the last CTX (approximately 6 months after baseline), and 1 year after baseline.

One key aspect of evidence-based psychological services is monitoring progress to inform treatment decision making, often using a brief self-report measure. However, no such measure exists to support measurement-based care, given the distinct needs of transgender and gender diverse people (TGD), a group facing large documented health disparities and marginalization in health care. The purpose of the present study was to develop and provide initial psychometric validation of a short, behavioral health progress monitoring self-report measure, the Trans Collaborations Clinical Check-in (TC).

CHIP/STUB1 ubiquitin ligase is a negative co-chaperone for HSP90/HSC70, and its expression is reduced or lost in several cancers, including breast cancer. Using an extensive and well-annotated breast cancer tissue collection, we identified the loss of nuclear but not cytoplasmic CHIP to predict more aggressive tumorigenesis and shorter patient survival, with loss of CHIP in two thirds of ErbB2 and triple-negative breast cancers (TNBC) and in one third of ER breast cancers. Reduced CHIP expression was seen in breast cancer patient-derived xenograft tumors and in ErbB2 and TNBC cell lines.

Article Synopsis
  • A study explored the potential therapeutic role of immune transformation for Parkinson's disease, building on over a decade of animal research showing that regulatory T cells (Tregs) could protect against neurodegeneration.
  • A phase 1 trial involved 20 Parkinson's patients and 17 non-Parkinsonian controls to test the immune modulator sargramostim, revealing some modest improvements in symptoms and Treg function compared to the placebo group.
  • While adverse events were reported in both groups (100% in sargramostim and 80% in placebo), the findings suggest that immune modulation may offer a new approach to treating Parkinson's disease, warranting further research with larger participant numbers.

The ubiquitin ligases CBL and CBL-B are negative regulators of tyrosine kinase signaling with established roles in the immune system. However, their physiological roles in epithelial tissues are unknown. Here, we used MMTV-Cre-mediated gene deletion on a null background, as well as a tamoxifen-inducible mammary stem cell (MaSC)-specific and double knockout ( DKO) using Lgr5-EGFP-IRES-CreERT2, to demonstrate a mammary epithelial cell-autonomous requirement of CBL and CBL-B in the maintenance of MaSCs.
