MicroRNAs can be found intracellularly incorporated into extracellular vesicles (EV-miRNAs) or extracellularly as cell-free miRNAs (cf-miRNAs). This study aimed to compare the diagnostic and prognostic potential of four miRNAs with recognized roles in prostate cancer as cf-miRNAs and EV-miRNAs, obtained from liquid biopsies (LB). Total RNA was isolated from whole plasma and plasma EVs from 15 controls (CTR) and 30 patients (20 with localized prostate cancer (PCa), 10 with metastatic prostate cancer (mPCa)).

Background: Alteration in DNA repair and metabolism genes can affect the maintenance of DNA integrity or xenobiotics metabolism, potentially leading to DNA damage accumulation. The present study investigated the association between polymorphisms in Glutathione S-Transferase Pi 1 (GSTP1, rs1695) and O-6-Methylguanine-DNA Methyltransferase (MGMT, rs2308321) genes with urothelial bladder cancer (UBC) susceptibility and prognosis. Furthermore, the methylation patterns of the promoter region of these genes were analyzed in tumor and non-tumor bladder tissues, besides MGMT gene expression in tumor samples.

Background And Aims: The most common adverse event (AE) of orthotopic liver transplantation (OLT) is anastomotic biliary stricture (ABS). Management varies widely between centers, and it is not clear whether a combination of endoscopic dilation of the stenosis followed by multiple plastic stents (MPS) or placement of a fully covered self-expandable metal stent (fcSEMS) is better for the management of post-OLT ABS. This systematic review and meta-analysis aimed to compare the efficacy, safety, and cost of fcSEMS versus MPS in the treatment of post-OLT ABS.

This meta-analysis aimed to compare the outcomes of video-assisted thoracic surgery (VATS) and open thoracotomy in pediatric patients undergoing pulmonary metastasectomy for various malignancies. We systematically searched PubMed, Embase, and Cochrane Library databases for studies comparing VATS and open thoracotomy in pediatric patients. The treatment effects for continuous outcomes were compared using mean differences (MDs), and binary endpoints were evaluated using odds ratios (ORs), with 95% confidence intervals (CIs).

Background: Colorectal cancer (CRC) is the second leading cause of cancer death worldwide. Early detection of precursor lesions or early-stage cancer could hamper cancer development or improve survival rates. Liquid biopsy, which detects tumor biomarkers, such as mutations, in blood, is a promising avenue for cancer screening.

Glioblastoma (GBM) is an extremely aggressive form of brain cancer that remains challenging to treat, especially owing to the lack of effective targeting and drug delivery concerns. Due to its anatomical advantages, the nose-to-brain strategy is an interesting route for drug delivery. Nanoengineering has provided technological tools and innovative strategies to overcome biotechnological limitations, which is promising for improving the effectiveness of conventional therapies.

Background: Photodynamic Therapy (PDT) is a therapeutic modality that combines the application of a photoactive compound (photosensitizer, PS) with low-power light to generate reactive oxygen species in the target tissue, resulting in cytotoxic damage and cell death, while sparing adjacent tissues. The objective of this study was to evaluate the phototoxicity of a cyanine dye with two chromophores (biscyanines, BCD) in systems with varying levels of cellular organization, and we used the Photogem® (a photosensitizer approved by the Brazilian ANVISA agency for clinical use in Photodynamic Therapy) as a positive control.
Materials And Methods: The cytotoxicity of the compounds was assessed in vitro in 2D monolayers, 3D spheroid cultures, and artificial skin models.

Background And Objectives: To evaluate the oncology outcomes in cervical cancer patients aged 25 years or younger and compare them with those in older patients.
Methods: Cervical cancer patients were retrospectively analyzed and divided into two groups: young patients (≤25 years) and older patients (>25 years). For each young patient, two controls were selected from the database of cervical cancer patients aged over 25 years, matched by FIGO stage, treatment, and histologic type.

Stereotactic biopsies are essential for obtaining accurate histopathological analysis to guide treatment decisions for deep-seated brain lesions. Manually guided methods, while commonly used and highly precise, can be limited by potential inaccuracies and insufficient tissue sampling. The emerging robot-assisted (RA) techniques offer enhanced precision and could address these limitations for improved accuracy.

Background: Lip exposure to carcinogens lead to several disorders, such as actinic cheilitis (AC) and lower lip squamous cell carcinoma (LLSCC). Although several studies have described important pathways in lip carcinogenesis, the comprehension of association of target genes in this process and their association with tumor microenvironment still need to be better understood.
Methods: Tissue samples of 30 AC and 17 LLSCC cases were included for histopathological analysis, immunohistochemical expression of CD4, CD8, and PD-L1, and fluorescence in situ hybridization for AURKA, AURKB, TP53, PTEN, CCND1, and MYC.

Purpose: Malignant ureteral obstruction is generally associated with a poor disease prognosis; therefore, managing these cases is challenging. We describe our experience in treating malignant ureteral obstruction with urinary diversion and the impact of these procedures on the indication for new antineoplastic therapy and survival.
Materials And Methods: We retrospectively reviewed the data of patients with advanced cancer associated with malignant ureteral obstruction who underwent urinary diversion at three tertiary institutions between January 2013 and July 2022.

The brain-derived neurotrophic factor (BDNF) gene plays an important role in modulating the stress-response axis and inflammation, which can be regulated by epigenetic mechanisms. BNDF methylation has been associated with stress-related psychiatric disorders such as depression, anxiety and post-traumatic stress. Previous studies have reported that stressful events are involved with long-lasting alterations in DNA methylation (DNAm) of the BNDF exon IV promoter, suggesting that glucocorticoids and inflammatory cytokines can regulate this process.

Health economic appraisals often rely on the assessment of health utilities using preference-based measures (PBM). The cancer-specific PBM, European Organisation for Research and Treatment of Cancer Quality of Life Utility - Core 10 Dimensions (EORTC QLU-C10D), was developed recently, and now needs to be validated in various clinical populations. In a multicenter, multinational prospective cohort study, we longitudinally collected EORTC QLQ-C30 and EQ-5D-5L data from patients with thyroid cancer.
