    Nature Cancer, Published online: 03 April 2026; doi:10.1038/s43018-025-01108-9Applications of digital pathology in clinical oncology have largely depended on the requirement for labeled data and model re-training. A study now presents PRET, a training-free framework with robust performance for pan-cancer diagnosis that adapts pathology foundation models to diverse tasks at inference stage, from screening and subtyping tasks to segmentation and metastasis detection tasks.

Applications of digital pathology in clinical oncology have largely depended on the requirement for labeled data and model re-training. A study now presents PRET, a training-free framework with robust performance for pan-cancer diagnosis that adapts pathology foundation models to diverse tasks at inference stage, from screening and subtyping tasks to segmentation and metastasis detection tasks.

A tumor-derived metabolite primes the leptomeningeal pre-metastatic niche

Nature Cancer, Published online: 03 April 2026; doi:10.1038/s43018-026-01138-x

Leptomeningeal metastases are a devastating complication of solid tumors; how this niche becomes pro-metastatic remains poorly understood. A study now reveals that tumor cells prime a pre-metastatic niche within the leptomeninges via exosome-derived 5-HIAA, triggering vascular leakiness and accumulation of disseminated tumor cells.

Leptomeningeal metastatic cancer cells induce a permissive choroid plexus vasculature through extracellular-vesicle-derived 5-HIAA signaling

Nature Cancer, Published online: 03 April 2026; doi:10.1038/s43018-026-01145-y

Huang, Hou, Yang et al. demonstrate that leptomeningeal metastatic cells favor the formation of a premetastatic niche by remodeling the choroid plexus vasculature through the serotonin metabolite 5-hydroxyindoleacetic acid, which signals into endothelial cells through the aryl hydrocarbon receptor.

PRET is a few-shot system for pan-cancer recognition without example training

Nature Cancer, Published online: 03 April 2026; doi:10.1038/s43018-026-01141-2

Li et al. present PRET, a few-shot system for pan-cancer detection not requiring model fine-tuning, validated it in multicenter datasets and found that it outperformed existing approaches across tasks and pathologists in lymph node metastasis detection.

Single-cell and spatial profiling in cancer biology and clinical oncology

Nature Cancer, Published online: 03 April 2026; doi:10.1038/s43018-026-01142-1

Izar and colleagues review the insights into cancer biology gained via single-cell analyses and spatial profiling and overview the challenges and opportunities associated with the implementation of these approaches to guide clinical discovery.

Decoding pediatric brain tumors via CSF-derived methylomes

Nature Cancer, Published online: 30 March 2026; doi:10.1038/s43018-026-01139-w

Cerebrospinal fluid (CSF)-derived cell-free DNA holds promise for CNS tumors, but its limited yield poses challenges. A study now presents M-PACT, a framework that uses sub-nanogram CSF-derived cell-free DNA methylomes for tumor classification, paving the way for minimally invasive diagnosis of pediatric brain tumors.

    Nature Cancer, Published online: 13 March 2026; doi:10.1038/s43018-026-01137-yRNA N6-methyladenosine (m6A) is the most abundant internal RNA modification, yet its functional landscape in cancer remains poorly defined. A study now introduces a METTL3-based RNA base-editing screen that maps functional m6A sites and reveals m6A-dependent translational activation of the tumor suppressor CHD9 in prostate cancer and beyond.

The genomic model P-CARE enables precision prostate cancer screening in a national healthcare system

Nature Cancer, Published online: 13 March 2026; doi:10.1038/s43018-025-01111-0

We developed and clinically implemented the genomic prostate cancer risk prediction model P-CARE that identifies men at a high or low risk of prostate cancer. P-CARE enabled the design and initiation of a precision screening trial across the national healthcare system in which it was developed.

Whether support from artificial intelligence (AI) models improves breast screening is a topic of research in national cancer screening programmes and clinical oncology. Three studies now show that AI tools can assist radiologists with evaluating mammograms, substantially reducing workloads and possibly improving screening performance.

Impact of using artificial intelligence as a second reader in breast screening including arbitration

Nature Cancer, Published online: 10 March 2026; doi:10.1038/s43018-026-01128-z

Warren et al. used data from a retrospective cohort of 50,000 women attending breast screening. Arbitration between human and AI decisions was performed in a reader study following normal arbitration workflow. After arbitration, replacing the second human reader with AI in a double-read breast screening workflow was noninferior to two human readers.
