Urol Oncol

November 2024

Bordeaux University Hospital, Urology department, Bordeaux, France; Kidney Cancer group of the French Association of Urology Cancer Committee, Paris, France.

Article Synopsis
  • Metastatic kidney cancer patients who respond well to immunotherapy are being reconsidered for primary surgery, particularly nephron-sparing surgery, due to their prolonged survival.
  • A study analyzed 13 patients who had partial nephrectomy after achieving complete responses to immunotherapy, finding no positive surgical margins and acceptable complication rates.
  • Results showed promising renal function and oncological outcomes, indicating that partial nephrectomy is feasible after immunotherapy, but more research is necessary for definitive conclusions.

Background: The optimal perioperative chemotherapy for patients with muscle-invasive bladder cancer is not defined. The VESPER (French Genito-Urinary Tumor Group and French Association of Urology V05) trial reported improved 3-year progression-free survival with dose-dense methotrexate, vinblastine, doxorubicin and cisplatin (dd-MVAC) versus gemcitabine and cisplatin (GC) in patients who received neoadjuvant therapy, but not in the overall perioperative setting. In this Article, we report on the secondary endpoints of overall survival and time to death due to bladder cancer at 5-year follow-up.

Background: A common method for diagnosing sarcopenia involves estimating the muscle mass by computed tomography (CT) via measurements of the cross-sectional muscle area (CSMA) of all muscles at the third lumbar vertebra (L3) level. Recently, single-muscle measurements of the psoas major muscle at L3 have emerged as a surrogate for sarcopenia detection, but its reliability and accuracy remain to be demonstrated.

Methods: This prospective cross-sectional study involved 29 healthcare establishments and recruited patients with metastatic cancers.

Neoadjuvant cisplatin-based chemotherapy (NAC) followed by radical cystectomy and pelvic lymph node dissection is the optimal treatment for patients with muscle-invasive bladder cancer. In recent years, the VESPER trial showed a statistically significant higher progression-free survival with dd-MVAC (dose dense methotrexate, vinblastine, doxorubicin, and cisplatin) compared to GC (gemcitabine and cisplatin). In the present report, we refine the characterization and outcome of patients whose cystectomy specimens were pathologically free of cancer (pathological complete response, pCR).

Article Synopsis
  • The ASXL1 gene is often mutated in blood cancers, particularly the c.1934dupG mutation, which is linked to worse patient outcomes, highlighting the need for better detection methods.
  • Researchers developed a new assay called "PCR-Fluo-ASXL1-FA" that rapidly and cost-effectively detects the c.1934dupG mutation and other nearby insertions/deletions, in contrast to less sensitive methods like direct sequencing.
  • Their study showed that this new approach is highly effective and should be used alongside next-generation sequencing (NGS) for comprehensive detection of ASXL1 mutations in myeloid malignancies.

Background: In metastatic seminoma, a strategy is needed for selecting patients for less intensive chemotherapy, to limit toxicities.

Objective: To assess whether men with good-prognosis metastatic seminoma could be treated with two cycles of etoposide-cisplatin (EP) followed by only one cycle of carboplatin (CARBO) based on negative interim fluorodeoxyglucose positron emission tomography (FDG-PET)/computed tomography (CT).

Design, Setting, And Participants: A nonrandomised, multicentre, phase 2 trial was conducted (NCT01887340).

Purpose: The optimal perioperative chemotherapy regimen for patients with nonmetastatic muscle-invasive bladder cancer is not defined.

Patients And Methods: Between February 2013 and March 2018, 500 patients were randomly assigned in 28 French centers and received either six cycles of dose-dense methotrexate, vinblastine, doxorubicin, and cisplatin (dd-MVAC) once every 2 weeks or four cycles of gemcitabine and cisplatin (GC) once every 3 weeks before surgery (neoadjuvant group) or after surgery (adjuvant group). We report the primary end point of the GETUG-AFU V05 VESPER trial (ClinicalTrials.

Article Synopsis
  • Cisplatin-based combination chemotherapy is the standard treatment for muscle-invasive bladder cancer before surgery, but the best chemotherapy options are still unclear.
  • In the VESPER trial, patients were given either gemcitabine and cisplatin (GC) or a more intense regimen called dd-MVAC, and their kidney function was monitored during treatment.
  • Results showed that at least 4 cycles of cisplatin are necessary for effective treatment, and while extending beyond 4 cycles does not worsen kidney function, it also does not provide significant additional benefits in local cancer control.

Over the past decade, immunotherapy has become a powerful and evident tool in the fight against cancers. Notably, the rise of checkpoint blockade using monoclonal antibodies (anti-CTLA4, anti-PD1) to avoid interaction between inhibitory molecules allowed the betterment of patient care. Indeed, immunotherapies led to increased overall survival in forms of cutaneous melanoma or lung cancer.

Background And Aims: The use of endoscopic treatment for early colorectal cancer (ECC) is increasing. The European guidelines suggest performing piecemeal endoscopic resection (pmR) for benign lesions and en bloc resection for ECC, especially for patients with favorable lymph node involvement risk evaluations. However, en bloc resections for lesions larger than two centimeters require invasive endoscopic techniques.

Background: Perioperative chemotherapy (neoadjuvant or adjuvant) has been developed to increase overall survival for nonmetastatic muscle-invasive bladder cancer (MIBC). Retrospective studies or prospective phase II trials have been reported to use dose-dense methotrexate, vinblastine, doxorubicin, and cisplatin (dd-MVAC) or gemcitabine and cisplatin (GC). As dd-MVAC has shown higher response rates in metastatic disease, better efficacy is expected in the perioperative setting.

Monoclonal antibodies (mAbs) against programmed cell death 1 (PD-1), such as nivolumab and pembrolizumab, are associated with high response rates in patients with relapsed or refractory classic Hodgkin lymphoma (HL). To date, no prognostic factor for overall survival (OS) has been established with these agents in HL. We examined whether the first early response assessment evaluated using F-FDG PET/CT may be associated with OS in this setting.
