Article Synopsis
  • The study aimed to assess the outcomes of bladder preservation therapy combining maximal TURBT and neoadjuvant chemotherapy in muscle-invasive bladder cancer patients.
  • A total of 110 patients were treated, with 61 achieving noninvasive downstaging, allowing them to preserve their bladders.
  • The findings indicated that bladder preservation therapy had comparable survival rates to radical cystectomy, but more research is necessary to confirm these results due to the retrospective nature of the study.

Purpose: To develop a deep learning (DL) model based on primary tumor tissue to predict the lymph node metastasis (LNM) status of muscle invasive bladder cancer (MIBC), while validating the prognostic value of the predicted aiN score in MIBC patients.

Methods: A total of 323 patients from The Cancer Genome Atlas (TCGA) were used as the training and internal validation set, with image features extracted using a visual encoder called UNI. We investigated the ability to predict LNM status while assessing the prognostic value of aiN score.

Bladder cancer (BC) is a prevalent urinary malignancy and muscle-invasive bladder cancer (MIBC) is particularly aggressive and associated with poor prognosis. One of MIBC features is the nuclear atypia. However, the molecular mechanism underlying MIBC remains unclear.

Background And Objective: Given the uncertainty regarding the role of radical nephroureterectomy (RNU) as part of a multimodal treatment strategy for upper tract urothelial carcinoma (UTUC) patients with cN+ disease, we aimed to perform a systematic review and meta-analysis of the corresponding literature.

Methods: Using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, we identified 17 observational comparative and noncomparative studies, published between January 2000 and September 2024, evaluating UTUC patients with cTanyN+M0 disease (P) who received RNU as part of a multimodal treatment strategy (I), as compared with any treatment strategy if applicable (C), to assess oncological or postoperative outcomes (O). Meta-analyses were further performed, as appropriate.

Department of Anatomy, Comparative Pathology and Toxicology, University of Córdoba, Campus de Rabanales, Córdoba, Spain.

Case Summary: A 13-year-old male castrated domestic shorthair cat presented with a 2-month history of progressive lameness, poor appetite and constipation. Physical examination revealed palpable lesions in muscles of several extremities. Ultrasound examination confirmed the presence of round lesions with a hypo- or anechoic centre within the muscles.
