Multi-pilot implementation experiences of patient-centered pathology reports: lessons learned for the advancement of patient-centered tools for cancer decision-making.

PURPOSE: New federal legislation in the United States grants patients expanded access to their medical records, making it critical that medical records information is understandable to patients. Provision of informational summaries significantly increase patient perceptions of patient-centered care and reduce feelings of uncertainty, yet their use for cancer pathology is limited. METHODS: Our team developed and piloted patient-centered versions of pathology reports (PCPRs) for four cancer organ sites: prostate, bladder, breast, and colorectal polyp. The objective of this analysis was to identify common barriers and facilitators to support dissemination of PCPRs in care delivery settings. We analyzed quantitative and qualitative data from pilot PCPR implementations, guided by the RE-AIM framework to explore constructs of reach, effectiveness, adoption, implementation, and maintenance. RESULTS: We present two case studies of PCPR implementation - breast cancer and colorectal polyps-that showcase diverse workflows for pathology reporting. Cross-pilot learnings emphasize the potential for PCPRs to improve patient satisfaction, knowledge, quality of shared decision-making activities, yet several barriers to dissemination exist. CONCLUSION: While there is promise in expanding patient-centered cancer communication tools, more work is needed to expand the technological capacity for PCPRs and connect PCPRs to opportunities to reduce costs, improve quality, and reduce waste in care delivery systems.

Enhancing upper tract urothelial carcinoma diagnosis: Utility of cytokeratin 17 and CK20/CD44/p53 immunohistochemical panel.

Upper tract urothelial carcinoma (UTUC) presents diagnostic challenges due to small biopsy specimen size, poor orientation, and technical obstacles that can yield equivocal diagnoses. This uncertainty often mandates repeated biopsies to evaluate the necessity of nephroureterectomy. Prior studies have suggested cytokeratin 17 (CK17) immunostain as an adjunctive tool for diagnosing bladder urothelial neoplasia in both urine cytology and tissue biopsy specimens. We evaluated the utility of CK17 in differentiating UTUC from benign urothelium and its ability to stratify low-grade from high-grade neoplasia. Our study involved a cohort of previously diagnosed cytology (n = 29) and tissue specimens from biopsies and resections (n = 85). We evaluated CK17 staining percentage in cytology and tissue samples and localization patterns in biopsy/resection samples. Our findings showed a statistically significant distinction (p < 0.05) between UTUC and benign tissue specimens based on full thickness localization pattern (odds ratio 8.8 [95% CI 1.53-67.4]). The percentage of CK17 staining failed to significantly differentiate neoplastic from non-neoplastic cases in cytology or tissue samples. Additionally, based on prior research showing the efficacy of CK20/CD44/p53 triple panel in bladder urothelial neoplasia, we utilized tissue microarrays to evaluate if these markers could distinguish UTUC from benign urothelium. We found that CK20/CD44/p53, individually or in combination, could not distinguish urothelial neoplasia from non-neoplasia. Full thickness CK17 urothelial localization by immunohistochemistry was highly reproducible with excellent interobserver agreement and may play a supplementary role in distinguishing upper tract urothelial neoplasia from benign urothelium.
