VIM-Polyp: Multimodal Colon Polyp Dataset with Video, Histopathology, and Protein Expression. (PubMed, Sci Data)
In combination with external datasets or pretrained models, the resource can help advance data-driven detection and characterisation work. The diverse range of polyps assigned to cancer stages from 201 patients makes this tool valuable for researchers and clinicians in furthering diagnosis and treatment.

Quantitative spatial profiling of PD-1/PD-L1 and TIGIT/CD155 interaction indicates poor survival outcome and resistance to adjuvant chemotherapy in pancreatic adenosquamous carcinoma. (PubMed, Eur J Cancer)
Quantitative spatial profiling of the PD-1/PD-L1 and TIGIT/CD155 suppression pathways using novel AQUA algorithms could help predict patient outcomes and ACT responses reliably, guiding development of more effective personalized management for PASC.

Trustworthy assessment of 2D model for lung CT scans. (PubMed, Annu Int Conf IEEE Eng Med Biol Soc)
Further investigations are required to mitigate these biases and ensure equitable model performance across diverse patient populations.Clinical relevance - The model identifies poor responders (patients with an overall survival of less than 6 months), potentially preventing unnecessary IO administration in NSCLC patients unlikely to benefit from the therapy. Additionally, it evaluates how variations in data distribution could impact the model performance.

A Real-World Study of Resectable NSCLC Following Neoadjuvant Immunotherapy: Should Postoperative Adjuvant Immunotherapy be Recommended? (PubMed, Thorac Cancer)
Postoperative adjuvant ICI therapy significantly improves EFS in resectable NSCLC patients, especially in those without pCR or MPR. However, its effect on OS remains uncertain. These findings highlight the importance of personalized treatment strategies, with adjuvant ICI offering greater benefits for patients with incomplete pathological responses.

UTP3: A Prognostic Marker in Hepatocellular Carcinoma and Its Role in Immunity and Epigenetics. (PubMed, J Biochem Mol Toxicol)
A nomogram centered on UTP3 yielded a 1-year AUC of 0.693. This multi-omics study establishes UTP3 as a key regulator connecting epigenetic alterations, immune suppression, and tumor progression in LIHC.

Human lysine oxidase-like 3 high expression as a potential biomarker and association with poor prognosis in pleural mesothelioma. (PubMed, Int J Biol Markers)
CD68, CD206, PD-L1, and LOXL3 may collaboratively contribute to the regulation of the PM microenvironment and are closely linked to the invasion and metastasis of PM. Therefore, LOXL3 can be used as both a prognostic marker and a potential therapeutic target for PM.

Pembrolizumab versus pembrolizumab plus chemotherapy in patients with PDL1 ⩾50% advanced non-small-cell lung cancer, depending on tumor aggressiveness and clinical impact. (PubMed, Ther Adv Med Oncol)
Pembrolizumab-CT was not associated with improved survival compared with pembrolizumab alone, in PDL1 ⩾ 50% advanced NSCLC patients, even in cases of aggressive disease. Chemotherapy-related toxicities may have had a negative effect on survival.

Mechanisms of immunotherapy in cutaneous squamous cell carcinoma in the tumor microenvironment. (PubMed, Front Immunol)
Building on this foundation, the potential clinical value of immune checkpoint inhibitors (cemiplimab, pembrolizumab) in treating advanced cSCC is summarized based on data from relevant clinical trials. This review is distinguished from general tumor immunotherapy reviews by offering dedicated references for cSCC precision immunotherapy. In addition, priority is emphasized for future investigations into combination therapy regimens and the development of personalized tumor vaccines.
