A recipe for chaos: Extrachromosomal DNA and the hallmarks of cancer
A major review published in Cell by Wong et al. examines how extrachromosomal DNA (ecDNA) — oncogenic genetic elements that detach from chromosomes — drives genomic instability and accelerated tumor evolution. The authors detail the mechanistic basis by which ecDNA escapes Mendelian inheritance rules, enabling rapid amplification of cancer-driving genes and fostering intratumor heterogeneity. The …
Spectrum, pathobiology, mechanistic insights and diagnostic challenges of post-CAR T cell therapy lymphoproliferative disorders
A comprehensive review published in Nature Reviews Clinical Oncology characterizes the spectrum of rare lymphoproliferative and lymphomatous disorders that can arise following chimeric antigen receptor (CAR) T cell therapy. The authors highlight recurrent pathological and molecular features of these post-treatment complications and identify factors that may drive clonal expansion and malignant tra…
CALYPSO: Final Results of Savolitinib and Durvalumab Combination in Metastatic Papillary Renal Cancer
The Journal of Clinical Oncology has published the final results of the CALYPSO trial evaluating the combination of savolitinib, a MET inhibitor, with durvalumab, an anti-PD-L1 immune checkpoint inhibitor, in patients with metastatic papillary renal cell carcinoma. Papillary RCC is a rare and historically difficult-to-treat subtype of kidney cancer with limited approved targeted options, making no…
[News] US EPA proposes easing ethylene oxide emission standards
The US Environmental Protection Agency has proposed regulatory changes that would roll back safeguards against air emissions of ethylene oxide (EtO), a substance classified as a Group 1 human carcinogen by the International Agency for Research on Cancer. Announced on March 17, 2026, the proposed rule would relax continuous emissions monitoring requirements at approximately 90 commercial sterilisat…
[News] Rare Cancers Bill to become law in UK
On February 27, 2026, the UK Parliament voted to enact the Rare Cancers Bill into law, a landmark piece of legislation aimed at accelerating research and improving treatments and survival outcomes for patients with rare cancers, including brain tumours and pancreatic cancer. The bill was introduced by Scott Arthur, a Labour Party Member of Parliament from Scotland and a practising medical doctor. …
[Comment] NICE 2026 guideline for the diagnosis and management of kidney cancer
The Lancet Oncology has published a commentary on the new 2026 NICE guideline for the diagnosis and management of kidney cancer, the sixth most common cancer in UK adults with approximately 13,900 new cases diagnosed annually. The piece highlights that kidney cancer incidence has nearly doubled since the 1990s and is projected to continue rising through 2040, while UK five-year relative survival r…
Male-biased Yap1-Cd276/B7-H3 axis for immune evasion in medulloblastoma
A study published in Cancer Cell by Abdelfattah and colleagues has identified a sex-biased mechanism of immune evasion in Sonic Hedgehog (SHH) medulloblastoma, revealing that male tumors preferentially rely on the YAP1 transcription co-activator to upregulate the immune checkpoint molecule CD276 (B7-H3). The research demonstrates that immune checkpoint molecules in medulloblastoma cancer cells are…
Lipid oxidation reprogramming in cancer-associated fibroblasts enhances CD8+ T cell cytotoxicity and therapeutic response
A study published in Cancer Cell by Ma et al. has identified a previously unrecognized subset of cancer-associated fibroblasts (CAFs) marked by PTGER3 expression that emerges in response to chemotherapy and exhibits elevated lipid oxidation. These specialized fibroblasts secrete the lipid mediator 11-HETE, which enhances CD8+ T cell killing capacity by suppressing PTEN-related signaling pathways w…
A photoreceptor state links aggressive brain tumors in children
A study published in Cancer Cell by Gudenas and colleagues reveals that three aggressive pediatric cancers — Group 3 medulloblastoma, pineoblastoma, and retinoblastoma — share a common tumor-associated photoreceptor gene signature rooted in transient developmental progenitor cells. The finding fundamentally reframes these distinct malignancies as diseases arising from a shared window of developmen…
Structuring pathology foundation models with domain knowledge
Researchers have developed KEEP, a novel vision-language foundation model for computational pathology that integrates hierarchical disease knowledge into its pre-training process through a structured disease graph. Published in Cancer Cell, the study by Zhou et al. demonstrates that this knowledge-guided approach shapes more meaningful semantic representations, leading to significantly improved ze…
