An optimised liver-first strategy for synchronous metastatic rectal cancer leads to higher protocol completion and lower surgical morbidity.

Introduction: The optimal management of rectal cancer with synchronous liver metastases remains debatable. Thus, we propose an optimised liver-first (OLF) strategy that combines concomitant pelvic irradiation with hepatic management. This study aimed to evaluate the feasibility and oncological quality of the OLF strategy.

Nomogram to predict disease recurrence in patients with locally advanced rectal cancer undergoing rectal surgery after neoadjuvant therapy: retrospective cohort study.

Introduction: Prognostic models can be used for predicting survival outcomes and guiding patient management. TNM staging alone is insufficient for predicting recurrence after chemoradiotherapy (CRT) and surgery for locally advanced rectal cancer. This study aimed to develop a nomogram to better predict cancer recurrence after CRT followed by total mesorectal excision (TME) and tailor postoperative management and follow-up.

Impact of long-term indwelling JJ stent on renal volume and renal function.

Background: Data is lacking about long-term impact of JJ stents (JJst) on renal parenchyma. The aim of the study was to assess the evolution of renal parenchyma in patients with JJst indwelling for more than two years, and to find predictive factors for the development of renal atrophy.

Methods: Consecutive patients with JJst indwelled for more than 24 months, with a history of cancer, were retrospectively included.

Case-Matched Comparison of Functional and Quality of Life Outcomes of Local Excision and Total Mesorectal Excision Following Chemoradiotherapy for Rectal Cancer.

Background: Neoadjuvant chemoradiotherapy followed by radical surgery is the standard curative treatment for mid- to low-rectal cancer. However, the combination of these treatments may affect patients' GI and genitourinary functions and their quality of life. In the cases of good clinical response to neoadjuvant treatment, local excision is a rectal sparing strategy that would limit these side effects.

Molecular Profiles of Advanced Urological Cancers in the PERMED-01 Precision Medicine Clinical Trial.

Introduction: The prognosis of advanced urological cancers (AUC) remains unfavorable, and few data are available regarding precision medicine.

Methods: the PERMED-01 prospective clinical trial assessed the impact of molecular profiling in adults with refractory advanced solid cancer, in terms of number of patients with tumor actionable genetic alterations (AGA), feasibility, description of molecular alterations, treatment, and clinical outcome. We present here those results in the 64 patients enrolled with AUC.

External validation of the computerized analysis of TRUS of the prostate with the ANNA/C-TRUS system: a potential role of artificial intelligence for improving prostate cancer detection.

Purpose: Prostate cancer (PCa) imaging has been revolutionized by the introduction of multi-parametric Magnetic Resonance Imaging (mpMRI). Transrectal ultrasound (TRUS) has always been considered a low-performance modality. To overcome this, a computerized artificial neural network analysis (ANNA/C-TRUS) of the TRUS based on an artificial intelligence (AI) analysis has been proposed.

Comparison Between Micro-Ultrasound and Multiparametric MRI Regarding the Correct Identification of Prostate Cancer Lesions.

Introduction: Multiparametric MRI (mpMRI) has become the standard imaging technique for the diagnosis of prostate cancer. However, mpMRI pathways are depending on experience, expertise, and information transfer from radiology to urology. Micro-ultrasound (Micro-US) is a new system, using high frequency (up to 29 MHz) and high resolution (down to 75 µm) ultrasound images.

Endoscopic Ultrasound-Guided Radiofrequency Ablation as an Future Alternative to Pancreatectomy for Pancreatic Metastases from Renal Cell Carcinoma: A Prospective Study.

Background: Pancreatic metastases (PM) from renal cell carcinoma (RCC) are rare, are associated with favorable outcomes and are usually handled by surgery or VEGFR inhibitors, which both have side effects. Endoscopic Ultrasound (EUS)-guided radiofrequency ablation (RFA) is an innovative approach to treat focally deep metastases and could be a relevant technique to control PM from RCC.

Methods: This monocentric, prospective study aimed to evaluate the safety and efficacy of EUS-RFA to treat PM.
