Non-muscle invasive bladder cancers (NMIBC) pTa-pT1 are depicted by a high risk of recurrence and/or progression with an unpredictable clinical evolution. Our aim was to identify, from the original resection specimen, tumors that will progress to better manage patients. We previously showed that A-FABP (Adipocyte- Fatty Acid Binding Protein) loss predicted NMIBC progression.

Article Synopsis
  • Intestinal issues like inflammation, dysbiosis (microbial imbalance), and permeability are observed in spondyloarthritis patients, but their role in the disease's development is still debated.
  • A study using a rat model tracked these intestinal changes at three stages of arthritis, finding increased zonulin (a marker of intestinal permeability) and pro-inflammatory cytokines at the early phases.
  • Results suggest that intestinal changes occur before arthritis symptoms develop, indicating that while these factors are related, they are not directly dependent on each other.

Human papillomavirus (HPV) 16 exhibits different variants that may differ in their carcinogenic risk. To identify some high-risk variants, we sequenced and compared HPV16 whole genomes obtained from a longitudinal cohort of 34 HPV16-infected women who had either spontaneously cleared their infection (clearance group or "C"), or developed cervical high-grade lesions following a viral persistence (group persistence or "P"). Phylogenetic analysis of paired samples obtained at the beginning (C0 or P0) and at the end (C2 or P2) of the follow-up (median intervals between C0-C2 and between P0-P2 were 16 and 36.

Article Synopsis
  • - High levels of Ki67 in breast cancers correlate with poor outcomes, and the study focused on the agreement between Ki67 levels from the Oncotype DX test and standard Ki67 measurements in early-stage ER+/HER2- breast cancers.
  • - The study found a low correlation (0.288) between Ki67 values from Oncotype DX and traditional lab methods, with Ki67 levels being significantly linked to event occurrences (p = 0.03) but not to event-free survival (EFS) (p = 0.26).
  • - The results suggest that while there’s a disconnect in Ki67 measurements, the gene may still hold prognostic potential, especially in regions lacking access to Oncotype DX

Article Synopsis
  • HPV is a significant risk factor for head and neck squamous cell carcinoma (HNSCC), which is on the rise globally, especially in younger patients under 45 years of age.
  • A study at Besançon University Hospital analyzed HPV DNA and p16 expression in HNSCC patients, including a group under 45 and one aged 45 and older.
  • Results showed that HPV infection prevalence was around 11.7%, and although HPV16 was the main strain identified, p16 expression levels were similar across both age groups, indicating potential for p16 as a general prognostic biomarker for HNSCC.

A growing body of evidence addressing the involvement of human cytomegalovirus (HCMV) in malignancies had directed attention to the oncomodulation paradigm. HCMV-DB infected human mammary epithelial cells (HMECs) in culture showed the emergence of clusters of rapidly proliferating, spheroid-shaped transformed cells named CTH (CMV-Transformed HMECs) cells. CTH cells assessment suggests a direct contribution of HCMV to oncogenesis, from key latent and lytic genes activating oncogenic pathways to fueling tumor evolution.

A growing body of evidence is recognizing human cytomegalovirus (HCMV) as a potential oncogenic virus. We hereby provide the first experimental in vitro evidence for HCMV as a reprogramming vector, through the induction of dedifferentiation of mature human mammary epithelial cells (HMECs), generation of a polyploid giant cancer cell (PGCC) phenotype characterized by sustained growth of blastomere-like cells, in concordance with the acquisition of embryonic stem cells characteristics and epithelial-mesenchymal plasticity. HCMV presence parallels the succession of the observed cellular and molecular events potentially ensuing the transformation process.

In the era of immunotherapies there is an urgent need to implement the use of circulating biomarkers in clinical practice to facilitate personalized therapy and to predict treatment response. We conducted a prospective study to evaluate the usefulness of circulating exosomal-PD-L1 in melanoma patients' follow-up. We studied the dynamics of exosomal-PD-L1 from 100 melanoma patients by using an enzyme-linked immunosorbent assay.

  • - Early detection and improved treatments for breast cancer have reduced mortality rates, but challenges remain in addressing triple negative breast cancer (TNBC), which currently lacks effective treatments.
  • - Researchers studied the expression of six autophagy genes in breast cancer tissues, finding increased levels of a specific gene in TNBC samples, which was also confirmed at the protein level.
  • - By inhibiting this gene in TNBC cell lines, the study showed that it plays a role in regulating cancer traits, suggesting it could become a new marker and potential therapeutic target for TNBC in the future.

Background: Human cytomegalovirus (HCMV) establishes a persistent life-long infection and increasing evidence indicates HCMV infection can modulate signaling pathways associated with oncogenesis. Breast milk is an important route of HCMV transmission in humans and we hypothesized that mammary epithelial cells could be one of the main cellular targets of HCMV infection.

Methods: The infectivity of primary human mammary epithelial cells (HMECs) was assessed following infection with the HCMV-DB strain, a clinical isolate with a marked macrophage-tropism.

Article Synopsis
  • The GABARAP family members play key roles in receptor transport and the autophagy process, with downregulated GABARAPL1 linked to poor prognosis in breast cancer patients.
  • Research utilized qRT-PCR, western blotting, and epigenetic quantification to investigate how epigenetic changes affect GABARAP family expression in breast cancer.
  • Findings indicate that reduced GABARAPL1 expression is associated with DNA methylation and histone deacetylation, suggesting that targeting epigenetic mechanisms and CREB-1 modulation could help in developing treatments for breast cancer.

As the detection of the BRAF V600E mutation has a direct impact on treatment decision, an accurate screening for BRAF mutations in patients with advanced or metastatic melanoma is mandatory. Nevertheless, BRAF oncogene mutation status between different samples from the same patient has been studied with conflicting results. This study investigated the intrapatient homogeneity of BRAF mutation status using pyrosequencing in primary tumors and different metastatic sites of melanoma patients.

Background: The Oncotype DX recurrence score (RS) assay has been validated for prediction of 10-year risk of distant recurrence and likelihood of benefit from chemotherapy in patients with estrogen receptor (ER)-positive, HER2-negative early breast cancer. Patients with high RS tumors have substantial benefit, and patients with low RS tumors have minimal if any benefit from chemotherapy. Tumor size is used as a key parameter when selecting patients for neoadjuvant chemotherapy.
