Despite the acknowledged merits of precision oncology (PO) and its increasing global implementation, its full potential for advancing care and prevention remains unrealized. The benefits are currently accessible to only limited patient segments because of multifaceted barriers. Successful implementation hinges on various factors-scientific complexities not limited to technical, clinical, regulatory, economic, administrative, and health care policy-related challenges.

Liquid biopsy (LB) has revolutionized molecular pathology, offering non-invasive insights into tumor biology. However, widespread adoption is hindered by a lack of standardized protocols, requiring robust quality control and harmonized workflows. Large-scale studies are needed to establish effective standard operating procedures (SOPs), particularly for circulating tumor DNA (ctDNA) assays tailored to different disease stages.

Extracellular vesicle (EV) monitoring can complement clinical assessment of cancer response. In this study, patients with advanced non-small cell lung cancer (NSCLC) undergoing osimertinib, alectinib, pembrolizumab or platinum-based chemotherapy ± pembrolizumab were enrolled. EVs were characterized using Bradford assay to quantify the circulating cell-free EV protein content (cfEV), and dynamic light scattering to assess Rayleigh ratio excess at 90°, z-averaged hydrodynamic diameter and polydispersity index.

Pathology laboratories are currently facing remarkable issues in the management of their archives due to the ongoing increase in the production of formalin-fixed paraffin-embedded (FFPE) blocks, which is often coupled with inadequate spatial and environmental storing conditions. The manual process of storage and retrieving further increases the likelihood of human-based mistakes, wastes professionals' working time, and, ultimately, widens reports signing turn-around times. In the present work, we outline the strategies underlying the development of an automated archive at the pathology services of the University of Modena.

Objective: ALK, ROS1, NTRK, and RET gene fusions and MET exon 14 skipping alterations represent fundamental predictive biomarkers for advanced non-small cell lung cancer (NSCLC) patients to ensure the best treatment choice. In this scenario, RNA-based NGS approach has emerged as an extremely useful tool for detecting these alterations. In this study, we report our NGS molecular records on ALK, ROS1, NTRK, and RET gene fusions and MET exon 14 skipping alterations detected by using a narrow RNA-based NGS panel, namely SiRe fusion.

Objective: Prostate cancer (PCa) is the most common cause of cancer-related deaths in men worldwide. BRCA1/2 genes are reported altered in approximately 1% and 8% of PCa cases, respectively. To date, formalin-fixed paraffin-embedded (FFPE) tissues have a consolidate use in the clinical practice, but with a significant drawback related to DNA/RNA degradation during the pre-analytical process.

Introduction: The advocacy Women Against Lung Cancer in Europe (WALCE) promoted the European Program for the Routine Testing of Patients With Advanced Lung Cancer (EPROPA) and provided a free-of-charge molecular profiling platform for NSCLC sample characterization with the aim of increasing the detection of targetable drivers and improving patients' access to clinical trials in Europe.

Methods: From January 2021 to December 2023, 20 centers located at five different European countries (Greece, Slovenia, Romania, Albania, and Italy) joined EPROPA, with 555 patients with advanced NSCLC registered to the program. Anonymized patients' clinical-pathological data were shared through the EPROPA web platform and tissue samples were collected at the Molecular Pathology Unit of the Reference Center (University of Turin) for molecular analyses.

Introduction: Personalized medicine has revolutionized the clinical management of patients with solid tumors. However, the large volumes of molecular data derived from next-generation sequencing (NGS) and the lack of harmonized bioinformatics pipelines drastically impact the clinical management of patients with solid tumors. A possible solution to streamline the molecular interpretation and reporting of NGS data would be to adopt automated data analysis software.

Introduction: Identifying mutations in the epidermal growth factor receptor (EGFR) gene is crucial for individualized treatment of non-small cell lung cancer (NSCLC) patients. Accordingly, several methodologies and instruments are now commercially available to detect these alterations. The aim of this study was to examine the performance of next generation sequencing (NGS) in detecting both common and uncommon EGFR gene mutations in advanced NSCLC patients.

While recent randomized controlled trials (RCT) have suggested superior overall survival (OS) outcomes with segmentectomy over lobectomy, questions remain regarding the comparability of these surgical procedures for treating early-stage non-small cell lung cancer (NSCLC). This systematic review and meta-analysis aimed to synthetize existing evidence and to compare the survival outcomes observed for stage IA NSCLC following segmentectomy or lobectomy. 40 studies (38 observational, 2 RCTs) encompassing 103,926 patients were analyzed.

The assessment of ctDNA has emerged as a minimally invasive avenue for molecular diagnosis and real-time tracking of tumor progression in NSCLC. However, the evaluation of ctDNA by amplicon-based NGS has been not endorsed by all the healthcare systems and remains to be fully integrated into clinical routine practice. To compare tissue single-gene with plasma multiplexed testing, we retrospectively evaluated 120 plasma samples from 12 consecutive patients with advanced non-squamous NSCLC who were part of a prospective study enrolling treatment-naïve patients and in which tissue samples were evaluated using a single-gene testing approach.

  • This study examines the effectiveness of Poly ADP-ribose polymerase inhibitors (PARPi) in patients with BRCA mutations undergoing treatment for advanced ovarian cancer.
  • A retrospective analysis of 79 patients revealed no significant differences in progression-free survival (PFS) based on specific BRCA domain defects or mutation types.
  • The findings suggest that the success of PARPi maintenance treatment is largely independent of the BRCA defects or mutations.

Introduction: Lung Cancer (LC) continues to be a leading cause of cancer-related mortality globally, largely due to the asymptomatic nature of its early stages and the limitations of current diagnostic methods such as Low-Dose Computed Tomography (LDCT), whose often result in late diagnosis, highlighting an urgent need for innovative, minimally invasive diagnostic techniques that can improve early detection rates.

Areas Covered: This review delves into the potential of genomic characterization and mutational profiling to enhance early LC diagnosis, exploring the current state and limitations of traditional diagnostic approaches and the revolutionary role of Liquid Biopsies (LB), including cell-free DNA (cfDNA) analysis through fragmentomics and methylomics. New genomic technologies that allow for earlier detection of LC are scrutinized, alongside a detailed discussion on the literature that shaped our understanding in this field.

Fine-needle aspiration (FNA) guided by ultrasound (US) has emerged as a highly precise diagnostic method for managing thyroid nodules, significantly diminishing unnecessary surgeries. The effectiveness of US-guided FNA is high when a single specialist performs the FNA procedure and the microscopy. This paradigm has paved the way for the evolution of interventional cytopathology, a specialist with a pivotal role in the preoperative diagnostic process, encompassing patient history review, clinical examination, FNA execution under US guidance, preparation, and microscopic interpretation of cytological samples.
