The usage of the paris classification system in urine cytology in the diagnosis of non-muscle-invasive bladder cancer: a retrospective single-center study.
Discov Oncol
January 2025
Institute of Clinical Medicine, Surgery, University of Eastern Finland, Kuopio, Finland.
Purpose: This retrospective single-center study aimed to determine the correlation between The Paris System (TPS) urine cytology classification, cystoscopy findings, and non-muscle-invasive bladder cancer diagnosis. In addition, we sought to identify factors that might explain the abnormal cytology classification in cases in which no malignancy was detected.
Methods: A Total of 855 patients evaluated with urine cytology between 2017 and 2020 at Kuopio University Hospital were included.
Intraoperative methylene blue staining is effective as a single mapping technique in the identification of sentinel lymph nodes in dogs with low-grade mast cell tumours.

Department of Veterinary Medical Sciences, University of Bologna, Bologna, Italy.
Objectives: The aim of this prospective study was to assess the association between methylene blue staining pattern and the presence of histologic nodal metastasis in dogs with low-grade mast cell tumour in low-resource settings for the efficient diagnosis of lymphatic spread.
Methods: Dogs with a single, cytologically low-grade mast cell tumour and no documented distant metastases were prospectively included and underwent surgery. Along with primary mast cell tumour removal, intraoperative sentinel lymph node mapping with peritumoral mast cell tumour injection and regional lymph node excision, regardless of whether blue dye was visible in the lymph node, were performed.
Early Outcomes from Proton Craniospinal Irradiation for Leptomeningeal Metastasis From Solid Tumors.
Adv Radiat Oncol
February 2025
Department of Radiation Oncology, The University of Texas MD Anderson Cancer Center, Houston, Texas.
Purpose: Treatment options for leptomeningeal metastasis (LM) are limited. A recent phase 2 study found that proton craniospinal irradiation (pCSI) was well-tolerated and improved survival. We report our experience with pCSI for solid-tumor LM.

February 2025
Department of Pathology, Massachusetts General Hospital, Boston, Massachusetts, USA.
Background: Major mutations (e.g., KRAS, GNAS, TP53, SMAD4) in pancreatic cyst fluid (PCF) are useful for classifying and risk stratifying certain cyst types, particularly in cases with nondiagnostic cytology.

January 2025
Laboratory Medicine Department, Faculty of Applied Medical Science, University of Al Baha, Saudi Arabia. Electronic address:
Background: Cigarette smoking is known to induce various cellular changes and proliferative activities within the oral mucosa. This study compares the effects of smoking on cellular proliferation and cytological alterations using the AgNORs and Pap staining methods.
Methods: We performed statistical analyses to evaluate the mean AgNORs count in smokers and non- smokers.
