Article Synopsis
  • The study aims to create an automated system for analyzing corneal nerves in IVCM images to better understand nerve features in dry eye disease (DED).
  • An encoder-decoder semi-supervised model was developed for segmenting corneal nerves, with impressive accuracy metrics compared to expert evaluations, and analyzed features in a dataset of DED patients versus healthy controls.
  • Results showed significant reductions in certain nerve characteristics in DED patients, particularly in whorl-like nerves, indicating that the inferior whorl region is crucial for assessing corneal nerve damage associated with DED.

Both concurrent chemoradiotherapy (CCRT) and induction chemotherapy (ICT) followed by CCRT are standard care of advanced nasopharyngeal carcinoma (NPC). However, tailoring personalized treatment is lacking. Herein, we established a radiogenomic clinical decision support system to classify patients into three subgroups according to their predicted disease-free survival (DFS) with CCRT and ICT response.

In this study, a dual-mode full-field optical coherence tomography (FFOCT) was customized for label-free static and dynamic imaging of corneal tissues, including donor grafts and pathological specimens. Static images effectively depict relatively stable structures such as stroma, scar, and nerve fibers, while dynamic images highlight cells with active intracellular metabolism, specifically for corneal epithelial cells. The dual-mode images complementarily demonstrate the 3D microstructural features of the cornea and limbus.

Background: Anti-PD-1 therapy and chemotherapy is a recommended first-line treatment for recurrent or metastatic nasopharyngeal carcinoma, but the role of PD-1 blockade remains unknown in patients with locoregionally advanced nasopharyngeal carcinoma. We assessed the addition of sintilimab, a PD-1 inhibitor, to standard chemoradiotherapy in this patient population.

Methods: This multicentre, open-label, parallel-group, randomised, controlled, phase 3 trial was conducted at nine hospitals in China.

The AJCC/UICC TNM classification describes anatomic extent of tumor progression and guides treatment decisions. Our comprehensive analysis of 8,834 newly diagnosed patients with non-metastatic Epstein-Barr virus related nasopharyngeal carcinoma (NPC) from six Chinese centers indicates certain limitations in the current staging system. The 8th edition of the AJCC/UICC TNM classification inadequately differentiates patient outcomes, particularly between T2 and T3 categories and within the N classification.

To investigate the patterns of local failure and prognosis in patients with locally recurrent nasopharyngeal carcinoma (rNPC) after primary intensity-modulated radiotherapy (IMRT). The data of 298 patients with locally rNPC after IMRT were retrospectively analyzed. Magnetic resonance images of the initial and recurrent tumors were reviewed and, for patients with extra-nasopharyngeal local recurrence, the gross tumor volume of local recurrence was transferred to the original IMRT plan for dosimetry analysis.

Background: Detectable Epstein-Barr virus (EBV) DNA levels and unsatisfactory tumor response to induction chemotherapy (IC) could be used to guide the risk-adapted treatment strategy of locoregionally advanced nasopharyngeal carcinoma (LANPC) before concurrent chemoradiotherapy. We aim to compare the efficacy and safety of concurrent chemotherapy using taxane plus cisplatin [double-agent concurrent chemotherapy (DACC) group] with those of cisplatin alone [single-agent concurrent chemotherapy (SACC) group] in high-risk LANPC.

Methods: Overall, 197 LANPC patients with detectable EBV DNA or stable disease (SD) after IC were retrospectively included.

Gemcitabine plus cisplatin (GP) chemotherapy is the standard of care for nasopharyngeal carcinoma (NPC). However, the mechanisms underpinning its clinical activity are unclear. Here, using single-cell RNA sequencing and T cell and B cell receptor sequencing of matched, treatment-naive and post-GP chemotherapy NPC samples (n = 15 pairs), we show that GP chemotherapy activated an innate-like B cell (ILB)-dominant antitumor immune response.

Article Synopsis
  • Concurrent chemoradiotherapy (CRT) is traditionally the standard treatment for stage II nasopharyngeal carcinoma (NPC), but evidence supporting the need for chemotherapy alongside intensity-modulated radiation therapy (IMRT) is limited.
  • This study aimed to determine if patients with low-risk stage II/T3N0 NPC could safely skip concurrent chemotherapy while receiving IMRT, involving a total of 341 adults across five hospitals in China.
  • Key outcomes measured included 3-year failure-free survival, overall survival, and quality of life, with 98% of participants completing the trial and a median follow-up of 46 months.

  • Post-stroke fatigue (PSF) is a common issue after acute ischemic stroke (AIS), and this study looked at the potential link between red blood cell distribution width (RDW) levels at admission and PSF.
  • The study included 206 AIS patients and found that higher RDW levels at admission were significantly associated with increased PSF, even after controlling for other factors.
  • The research suggests that RDW could be a useful biomarker for identifying patients at risk for PSF in the early stages following an AIS.
