A case of malignant cutaneous lesion of the face diagnosed initially as sebaceous carcinoma, subsequently proven to be squamous cell carcinoma is presented. Patient was initially evaluated at an outside institution by computed tomography, which indicated extension of lesion to the maxillary sinus. Patient underwent local resection. Further imaging by magnetic resonance imaging was done for recurrent tumour. Examination revealed extensive, large volume, perineural extension of the disease via infraorbital nerve to the cavernous sinus. Patient was managed with extensive lesion resection, including the skull base component followed up by radiation. Patient showed recurrence despite aggressive management. This case highlights the crucial role of performing an optimal MR imaging of the target region, including skull base, to exclude a perineural extension, as part of assessment of oro-facial malignancy.

The utilization of plant-derived exosome-like nanovesicles (ELNs) as nanocarriers for oral delivery of bioactives has garnered significant attention. However, their distinctive lipid membrane composition may result in elevated membrane permeability within the gastrointestinal environment, leading to the leakage of carried bioactives. Inspired by the concept of projectile design, Tartary buckwheat-derived ELNs (TB-ELNs) based dual-carriers are fabricated by loading chlorogenic acid (CGA) into the cores and bonding selenium nanoparticles (SeNPs) to the lipid membrane.

This study evaluated the efficacy and safety of camrelizumab combined with platinum-based chemotherapy (taxanes [T] or fluorouracil agents [F] plus platinum [P] drugs) as the first-line treatment in advanced esophageal squamous cell carcinoma (ESCC), using immune repertoire sequencing (IRS) to explore treatment response mechanism. In this multi-center, prospective cohort study, 88 patients received camrelizumab plus TP or FP, achieving a 1-year progression-free survival of 56.8% and overall survival of 68.

Objective: Prostate cancer (PCa) is a complex disease characterized by diverse cellular ecosystems within the tumor microenvironment (TME) and high tumor heterogeneity, which challenges clinically stratified management and reinforces the need for novel strategies to fight against castration-resistant PCa (CRPC).

Methods: We performed single-cell RNA sequencing (scRNA-seq) on 10 untreated primary PCa tissues and integrated public scRNA-seq resources from three normal prostate tissues, two untreated primary PCa tissues, and six CRPC tumors to portray a comprehensive cellular and molecular interaction atlas of PCa. We further integrated the single-cell and bulk transcriptomes of PCa to establish a molecular classification system.

Objective: This study aims to assess the mesenchymal-epithelial transition factor's (c-MET) prognostic value in oesophageal carcinoma (ESCA) through a meta-analysis and bioinformatics.

Methods: We analysed c-MET expression in ESCA tissues using data from The Cancer Genome Atlas (TCGA) and conducted a meta-analysis to evaluate its association with clinicopathological factors and survival outcomes. The meta-analysis included studies reporting hazard ratios (HRs) and odds ratios (ORs) for survival and metastatic outcomes.

This study aimed to synthesize cetuximab (CTX) conjugated hydroxyapatite zirconium (HApZr-CTX) as a nanocarrier for active delivery of photosensitizer and therapeutic radionuclide. The system enabled targeted radioenhancer in X-ray dynamic therapy and radioimmunotherapy for lung cancer. The results showed that HApZr-CTX had the main characteristics of hydroxyapatite crystal in X-ray powder diffraction (XRD), with particle size twice bigger, according to DLS-PSA and TEM measurements.
