Super-resolution MRI and 2.5D deep learning for intratumoral-peritumoral radiomics in preoperative prediction of rectal cancer perineural invasion

Yuhang Wang, Dandan Dong, Shengming Shi, Yupeng Wu, Apekshya Singh, Jiayi Xie, Qiuyang Chen, Jianwei Zhu, Xiaofu Li

Abstract Objectives Preoperative prediction of perineural invasion (PNI) in rectal cancer (RC) is challenging due to limited MRI resolution and the neglect of extramural microenvironmental features. We developed a noninvasive framework integrating super-resolution MRI, 2.5D deep learning (DL), and intratumoral-peritumoral radiomics for preoperative PNI prediction. Materials and methods A dual-center cohort of 312 RC patients with pathologically confirmed PNI status was analyzed. Preoperative MRI underwent 4× super- …

The Stalk Sign in Bladder Cancer: CEUS Versus MRI

Fabrizio Urraro, Nicoletta Giordano, Vittorio Patanè, Maria Chiara Brunese, Giuseppe Ambrosio, Anna Russo, Roberto Calbi, Antonio Cioffi, Alfonso Reginelli

Background: The fibrovascular stalk is characteristic of papillary bladder tumors and may be visualized on MRI as the inchworm sign. Contrast-enhanced ultrasound (CEUS) may depict the same structure dynamically by demonstrating pedicle perfusion before tumor enhancement. We hypothesized that CEUS would be more sensitive than the MRI inchworm sign for detecting a histologically confirmed fibrovascular stalk and that stalk presence would be associated with non-muscle-invasive bladder cancer without completely excludi …

Exploring the Utility of ALDH1 as a Marker for the Cancer Stem Cell Population in OCCC Cell Lines

Blane Gebreyes, Bart Kolendowski, Yudith Ramos-Valdes, Trevor G. Shepherd, Gabriel E. DiMattia

Metastasis, chemoresistance, and tumour recurrence are facilitated by cancer stem cells (CSCs), a small subpopulation of cells capable of regenerating a primary tumour while maintaining the tumour’s genetic and phenotypic features. CSCs can be identified by the expression of specific markers; however, the CSC population in ovarian clear cell carcinoma (OCCC), a rare histotype of ovarian cancer, remains poorly defined. Given the well-established role that CSCs play in cancer progression and metastasis, it is critica …

NEK2-AURKA axis drives ubiquitin-dependent IFT88 degradation to suppress ciliogenesis and promote basal-type bladder cancer

E Du, Wei Wang, Qiang Su, Wei Huang, Yuanjiong Qi, Weijie Tang, Zhihong Zhang, Changwen Zhang, Jingxian Li

Abstract Loss of primary cilia is common in cancer, but its relevance to molecular subtypes of muscle-invasive bladder cancer (MIBC) is unclear. Here, we combined transcriptomic and co-expression analyses with experiments in bladder cancer cell lines, human tumor specimens, and xenografts to investigate the basis of cilia loss in basal MIBC. Primary cilia were less frequent in basal than in luminal MIBC. Depletion of IFT88 reduced ciliogenesis and increased cell proliferation and migration. Conversely, IFT88 overex …

In Situ Construction of a Reticulated Peptide Scaffold via Responsive Self-Assembly and Proximal Covalent Labeling for Enhanced Tumor Imaging and Therapy

Ruxin Feng, Yunfeng Qiu, Yang Zhao, Rixin Wang, Weilu Xu, Jinhui Ning, Yumin Li, Juyue Zhou, Dingqing Feng, Suying Xu, Leyu Wang

Abstract Precise imaging and specific retention of therapeutic agents at solid tumors were particularly desirable yet hindered by limited specificity and fast diffusion. Herein, we established a dual-trigger-mediated synergistic strategy to form a reticulated peptide network in situ by functional peptide (CL-YPFG) through responsive self-assembly and covalent labeling for prolonged imaging and boosted accumulation of drugs. Specifically, the CL-YPFG underwent morphology transformation from nanoparticles to nanofibe …

Whole-Exome Sequencing Identifies Candidate Genomic Features Associated with Response to Platinum-Based Chemotherapy and Ixabepilone-Based Treatment in Ovarian Cancer

Tobias M. P. Hartwich, Stefania Bellone, Orazio De Tommasi, Sarah Ottum, Victoria Ettorre, Michelle Greenman, Namrata Sethi, Cem Demirkiran, Kevin Y. Yang, Ammal Abbasi, Ludmil B. Alexandrov, Alessandro D. Santin

Carboplatin/paclitaxel (CP) chemotherapy is the cornerstone of therapy for advanced stage ovarian cancer (OC). However, despite initial sensitivity, this regimen cannot avoid the emergence of resistance. Ixabepilone ± bevacizumab (IB) is a combination recently added to NCCN guidelines for the treatment of platinum-resistant OC. It would be desirable to identify biomarkers able to differentiate patients who are resistant to CP and IB, and biomarkers that identify which patients may benefit from IB treatment. We anal …

Engineering Biomimetic Tumor Organoids Inspired by Janus Stiffness–Driven Cell Stemness

Ziyu Zhu, Siyi Zhou, Tianyi Gu, Yu Liu, Kuoran Xing, Jiaxing Gong, Lixuen Siow, Yun Jiang, Xin Ye, Kejie Lu, Yemu Yang, Yunxia Gao, Jianlu Kong, Ying Qian, Chaoying Zhang, David Tai Leong, Huiming Wang, Mengfei Yu

ABSTRACT Organoids become powerful platforms for modeling cancer biology but poorly preserve stemness due to inadequate biophysical cues. Cancer stem cells (CSCs), crucial for tumor growth, are rare and lose stemness under conventional in vitro conditions, limiting drug screening. While chemical and genetic stemness regulators are identified, the role of spatial matrix mechanics remains unclear and largely absent from current organoid architectures. Here, we demonstrate that stemness depends not on stiffness alone …
