Importance: Cancer and its care impose significant time commitments on patients and care partners. The oncology community has only recently conceptualized these commitments and the associated burden as the "time toxicity" of cancer care. As the concept gains traction, there is a critical need to fundamentally understand the perspectives of multiple stakeholders on the time burdens of cancer care.

Real-world data: bridging the gap between clinical trials and practice.

EClinicalMedicine

December 2024

Department of Oncology, Queen's University, Kingston, Ontario, Canada.

Real-world data (RWD) are rapidly emerging sources of information for patients, clinicians and regulators. While randomized controlled trials (RCTs) reduce bias and confounding through the randomization process and provide the highest quality of evidence regarding drug efficacy, RCTs may be impractical or unfeasible for rare diseases or disease subsets. And yet, studies attempting to replicate clinical trial results using observational datasets have failed.

Objectives: Adolescents and young adults (AYAs, 18-39 years) with cancer identifying as racially/ethnically minoritized or 2SLGBTQIA+ (Two-Spirit, lesbian, gay, bisexual, transgender, queer, intersex, asexual and "+" referring to other queer identities) have been underrepresented in cancer research. This study explores the aspects of identity that hold significance for these minoritized AYAs and how these facets impact their healthcare experiences.

Methods: Eligible participants comprised English-speaking AYAs who self-identified as racially/ethnically minoritized and/or 2SLGBTQIA+, were diagnosed with cancer between the ages of 15-39, currently aged > 18, and had received or were receiving cancer care within Canadian healthcare system.

Despite the clinical success of dozens of genetically targeted cancer therapies, the vast majority of patients with tumors caused by loss-of-function (LoF) mutations do not have access to these treatments. This is primarily due to the challenge of developing a drug that treats a disease caused by the absence of a protein target. The success of PARP inhibitors has solidified synthetic lethality (SL) as a means to overcome this obstacle.

Antibody-drug conjugates (ADCs) represent an effective class of agents for the treatment of several tumor types, including breast cancer (BC), featuring approved molecules such as trastuzumab-emtansine, trastuzumab-deruxtecan, and sacituzumab-govitecan. Immune-checkpoint inhibitors (ICIs) also showed activity in selected BC subtypes, and two agents, pembrolizumab and atezolizumab, are currently approved for the treatment of triple-negative BC patients. The potential synergy between ADCs and immunotherapy in BC remains an area of active investigation.

As indications for immune checkpoint inhibitors for breast cancer continue to expand, rare toxicities will emerge that require careful consideration and multidisciplinary management. We report the case of a 40-year-old female receiving neoadjuvant pembrolizumab and chemotherapy for locally advanced triple-negative breast cancer who developed cytokine release syndrome (CRS)/hemophagocytic lymphohistiocytosis (HLH). CRS/HLH secondary to pembrolizumab are scarcely documented in the literature and, to our knowledge, have never been reported in the context of neoadjuvant treatment for breast cancer.

Background: Failure of immunotherapy in high-grade serous ovarian cancer (HGSC) may be due to high levels of transforming growth factor-β (TGF-β) in ascites or tumour immune microenvironment (TIME). Here, we test whether coordinated blockade of TGF-β and PD-L1 with bintrafusp alfa (BA) can provoke anti-tumour immune responses in preclinical HGSC models.

Methods: BA is a first-in-class bifunctional inhibitor of TGF-β and PD-L1, and was tested for effects on overall survival and altered TIME in syngeneic HGSC models.

Actin barbed end-binding macrolides have been shown to inhibit cancer cell motility and invasion of extracellular matrix (ECM), evoking their potential utility as therapies for metastatic cancers. Unfortunately, the direct use of these compounds in clinical settings is impeded by their limited natural abundance, challenging total synthesis, and detrimental effects on normal tissues. To develop potent analogues of these compounds that are simpler to synthesize and compatible with cell-specific targeting systems, such as antibodies, we designed over 20 analogues of the acyclic side chain (tail) of the macrolide Mycalolide B.

Article Synopsis
  • Researchers looked at the costs and benefits of a special genetic test called NGS for patients with advanced cancer in a study done in Canada.
  • The study compared patients who had the NGS test to those who didn’t, to see if it helped them live longer or join clinical trials.
  • They found that while the NGS test cost more, it did lead to more patients joining clinical trials and had better quality of care at the end of life, but it didn't really help them live longer overall.
