The authors present a retrospective analysis of the results of transurethral conservative and radical operations in 125 patients with invasive cancer of the urinary bladder (UB) treated in the Research Institute of Urology throughout 1992-2002. Transurethral resection (TUR) of the UB was made in 72 patients. Stages pT2a, pT2b, T3 and T4 were diagnosed in 23 (31.9%), 18 (25%), 14 (19.5%) and 17 (23.6%) cases, respectively. 53 patients with advanced invasive UB cancer have undergone radical cystectomy varying by the method of urine derivation. Stages pT2N0M0, pT3aN0M0, pT3bN0M0, pT4aN0M0 and N1-2 were registered in 4 (7.5%), 13 (25%), 21 (40%), 7 (12.5%) and 8 (15%) patients, respectively. UB cancer recurrences after TUR occurred in 12 (16.7%) patients with stage pT2a, in 8 (11.1%) patients with stage pT2b. Three-year overall and recurrence-free survival after TUR at stage T2 reached 97.5 +/- 3.2 and 47.4 +/- 2.8, respectively, at stage T3 and T4--57.1 +/- 4.3 and 26.6 +/- 3.4%, respectively. Postcystectomy distant metastases to the lungs, bones and iliac lymph nodes after treatment were detected in 3, 2 and 3 patients, respectively. One patient had a local pelvic recurrence. For all 53 patients a 2-year corrected survival made up 68 +/- 12.0%. Thus, transurethral electrosurgery is an effective treatment of invasive UB cancer; the only radical surgical treatment for invasive UB cancer is cystectomy.

Background: With advancements in minimally invasive thoracic surgery techniques, such as video-assisted thoracoscopic surgery and robotic surgery, the design of vascular staplers has evolved to meet the requirements of these procedures. Consequently, newer generations of automatic staplers with improved handling and reduced size have been introduced, such as two-row staplers, which are more maneuverable and less bulky than their three-row counterparts.

Case Presentation: A 68-year-old man with lung cancer underwent a right middle and lower lobectomy due to tumor invasion into the central middle bronchial trunk, rendering the preservation of the middle lobe impossible.

Background: Bone marrow mesenchymal stem cells (BMSCs) are a crucial component of the tumor microenvironment (TME), with hypoxic conditions promoting their migration to tumors. Exosomes play a vital role in cell-to-cell communication within the TME. Hypoxic TME have a great impact on the release, uptake and biofunctions of exosomes.

Background: Abundant research indicates that increased extracellular matrix (ECM) stiffness significantly enhances the malignant characteristics of hepatocellular carcinoma (HCC) cells. Plectin, an essential cytoskeletal linker protein, has recently emerged as a promoter of cancer progression, particularly in the context of cancer cell invasion and metastasis. However, the responsiveness of plectin to changes in ECM stiffness and its impact on HCC progression remain unclear.

Background: LINC00312 has shown to play a suppressive role in the development and progression of non-small cell lung cancer (NSCLC). However, the expression pattern and diagnostic role of circulating LINC00312 in NSCLC remain to be confused.

Methods: A total of 319 patients diagnosed with NSCLC and 180 healthy volunteers were enrolled from the First Affiliated Hospital of Huzhou University between January, 2022 and December, 2023.

Ultrasound-guided Transperineal Prostate Thermal Ablation (TPTA) for Benign Prostatic Hyperplasia: Feasibility of an Outpatient Procedure using Radiofrequency Ablation.

Cardiovasc Intervent Radiol

January 2025

Department of Radiology, Universidade Federal de São Paulo (UNIFESP), Rua Dr. Ovidio Pires de Campos, 75, Cerqueira César, São Paulo, SP, 05403-010, Brazil.

Purpose: To evaluate the feasibility, safety, and short-term (3-month) results of transperineal prostate thermal ablation (TPTA) as a minimally invasive outpatient treatment for benign prostatic hyperplasia (BPH).

Materials And Methods: A prospective nonrandomized study of 25 patients with lower urinary tract symptoms secondary to BPH seeking care at 2 interventional radiology centers between March and July 2024. TPTA was performed using a 17G radiofrequency needle with a 10-mm active tip under unconscious sedation combined with bilateral perineal and periprostatic nerve blocks.
