The International System for Serous Fluid Cytopathology (TIS) survey in preparation for TIS 2.0.

Introduction: The International System for Serous Fluid Cytopathology (TIS) has gained acceptance and has led to literature validating original concepts and suggesting refinements. In preparation for the second edition of TIS, editors generated a survey to solicit experience with and opinions about TIS.

Materials And Methods: An online survey available from March 8 to June 15, 2024, included 56 questions, offered in 7 languages, related to the practice of serous fluid cytopathology.

Tools, techniques, and challenges in preparing cytology specimens for ancillary studies: results of the ASC Optimizing Cytology and Small Biopsy Specimen Processing for Ancillary Studies task force survey.

Introduction: Ancillary testing on cytopathology and other small biopsy specimens is crucial for diagnosis and provides critical information to clinicians. Testing is dependent on preanalytic factors and would benefit from standardization of specimen collection protocols across laboratories. To assess institutional practices and areas of need for evidence-based standards, we surveyed current practices across cytopathology laboratories.

Is prostatic adenocarcinoma detectable by urine cytology-A multicenter retrospective review.

Introduction: Urine cytology is robust for the diagnosis of urothelial lesions, but data on the detection rates of prostatic adenocarcinoma in urine cytology is limited. In this study, a multicenter review was performed to define the clinical role of urine cytology in diagnosis of prostatic adenocarcinoma.

Methods: Cytologic diagnoses of lower tract urine cytology specimens with histology-proven prostatic adenocarcinoma from three institutions, from a period of over two decades, were reviewed.
