The Safety and Suitability of DNA Sequencing of Tissue Biopsies Performed on Patients Referred to a Phase I Unit.

Background: Early-phase clinical trials offer a unique opportunity for patients with cancer. These trials often mandate biopsies to collect tumor tissue for research purposes, requiring patients to undergo invasive procedures. Some trials mandate molecular prescreening, but the success of these analyses relies on the quality and quantity of the tested materials.

Microwave vs radiofrequency ablation for small renal masses: perioperative and oncological outcomes.

Objective: To conduct a comprehensive comparison of microwave ablation (MWA) vs radiofrequency ablation (RFA) outcomes in the treatment of small renal masses (SRMs), specifically: TRIFECTA ([i] complete ablation, [ii] absence of Clavien-Dindo Grade ≥III complications, and [iii] absence of ≥30% decrease in estimated glomerular filtration rate) achievement, operative time (OT), and local recurrence rate (LRR).

Patients And Methods: We retrospectively analysed 531 patients with SRMs (clinical T1a-b) treated with MWA or RFA at a single centre (2008-2022). First, multivariable logistic regression models were used for testing TRIFECTA achievement.

Despite the significant improvement of knowledge and technologies in tumor treatments, pancreatic tumor remains a complex disease still characterized by a poor prognosis. The increasing role of minimally invasive techniques started to drive the effort of scientific medicine to evaluate the possibilities of application of these techniques to pancreatic cancer. The purpose of this paper is to present a brief summary of the different ablative techniques available and proposed for pancreatic tumor treatment considering invasive, noninvasive, thermal and non-thermal techniques.

Cone-Beam CT-Assisted Ablation of Renal Tumors: Preliminary Results.

Introduction: Renal ablation is a recognized treatment modality for small renal masses. Cone-beam CT (CBCT) has been recently used in interventional oncology as a promising new guidance device, but this technology still needs to be validated for renal ablations. We aimed to assess the technical success of CBCT applications in renal ablative treatments.

Percutaneous laser ablation for benign and malignant thyroid diseases.

Minimally invasive image-guided thermal ablation is becoming increasingly common as an alternative to surgery for the treatment of benign thyroid nodules. Among the various techniques for thermal ablation, laser ablation (LA) is the least invasive, using the smallest applicators available on the market and enabling extremely precise energy deposition. However, in some cases, multiple laser fibers must be used simultaneously for the treatment of large nodules.

Long-term survival with erlotinib in advanced lung adenocarcinoma harboring synchronous EGFR G719S and KRAS G12C mutations.

Although epidermal growth factor receptor (EGFR) and v-Ki-ras2 Kirsten rat sarcoma viral oncogene (KRAS) mutations were thought to be mutually exclusive in patients with non-small cell lung cancer (NSCLC), the development of high sensitive large-scale mutation analysis, has increasingly shown that activating EGFR mutations occasionally coexist with other dominant genetic alterations. Herein, we discuss the case of a patient with advanced NSCLC harboring both the uncommon EGFR G719S and the KRAS G12C mutations, who was treated for 9 years with erlotinib achieving a long-term survival. In light of their rarity, multiple mutations are very challenging for the decision of tyrosine kinase inhibitors (TKIs) treatment, especially when EGFR mutations occur together with mutations known to provide resistance to EGFR TKIs, such as KRAS.

Comparison between locked and unlocked intramedullary nails in intertrochanteric fractures.

Background: Intertrochanteric fractures are of great interest worldwide and are the most frequently operated fractures. Intramedullary nailing is commonly used in the treatment of intertrochanteric fractures. The purpose of this study is to assess the necessity of using the distal blocking screw in 31-A1 and 31-A2 fractures, classified according to the Orthopaedic Trauma Association classification system (AO/OTA).

CT-Guided Percutaneous Trans-scapular Lung Biopsy in the Diagnosis of Peripheral Pulmonary Lesion Nodules of the Superior Lobes Using Large Needles.

Purpose: CT-guided percutaneous transthoracic lung needle biopsy (PLB) is an effective procedure for obtaining cyto-histological diagnoses of peripheral lesions. However, upper postero-lateral lung nodules (UPLN) may be difficult to reach using a standard intercostal either anterior or lateral approach or when the nodule is just behind a rib or scapula. We evaluated the feasibility and effectiveness of trans-scapular approach (tPLB) in these patients using large-core needles.
