Antibiotic therapy impact on intravesical BCG therapy efficacy for high-risk localized bladder cancer treatment.

Intravesical Bacillus Calmettes-Guerin (BCG) instillations is the gold standard adjuvant treatment for high and very high-risk non-muscle-invasive bladder cancer (NMIBC). Antibiotics may be required to treat asymptomatic bacteriuria before instillations or to prevent side effects. By modifying the bladder microbiota and through its bactericidal action, it could modify the efficacy of BCG.

Long-Term Oncological and Functional Outcomes after Laparoscopic Partial Nephrectomy with Hyperselective Embolization of Tumor Vessels in a Hybrid Operating Room.

Laparoscopic partial nephrectomy (LPN) after hyperselective embolization of tumor vessels (HETV) in a hybrid operating room (HOR) that combines traditional surgical equipment with advanced imaging technology, is a non-clamping surgical approach to treat localized kidney tumors that has shown promising short-term results. The aim of this study was to evaluate the long-term oncological and functional outcomes of this procedure. All consecutive patients treated for a localized kidney tumor by LPN after HETV between May 2015 and October 2022 in a single academic institution were included in the study.

[Impact of delay before partial nephrectomy of a localized kidney tumor].

Introduction: Partial nephrectomy is the treatment of choice for small localized renal tumors. In case of doubt, a biopsy can confirm the diagnosis. The aim of this study was to evaluate the impact of a delayed time to partial nephrectomy on cancer development.

Histopathology of prostate tissue after vascular-targeted photodynamic therapy for localized prostate cancer.

Low-risk prostate adenocarcinoma is classically managed either with active surveillance or radical therapy (such as external radiotherapy or radical prostatectomy), but both have significant side effects. Vascular-targeted photodynamic therapy (VTP) is a focal therapy proposed as an alternative approach for localized, low-volume, and low-Gleason score (≤6) carcinomas. We report histological modifications observed in prostate biopsies of 56 patients, performed 6 months after VTP using the photosensitizer TOOKAD® Soluble (WST11) and low-energy laser administered in the tumor area transperineally by optic fibers.
