We evaluated 35 male autopsy cases with sATTR-CA. The severity of prostatic and cardiac ATTR deposition was assessed semiquantitatively. Using digital pathology, we quantitatively evaluated the immunohistochemical deposition burden of ATTR in the prostatic interstitium and myocardium. Amyloid deposition was detected in 18 cases (51%) in haematoxylin and eosin (H&E)-stained specimens, and ATTR deposition was confirmed in 29 cases (83%) using Congo red staining and immunohistochemistry for transthyretin. The group with identifiable amyloid deposition in the prostate on H&E staining had significantly more severe ATTR deposition in the heart than the group without prostatic deposition. The severity of deposition at all prostatic sites correlated positively with semiquantitative and quantitative deposition severity scores in the heart. Notably, the severity of deposition in the prostatic intraglandular interstitium and extraglandular vessels showed a strong positive correlation with the severity of sATTR-CA. Prostatic ATTR deposition was prevalent and may be a useful organ for diagnosing ATTR deposition. Additionally, the severity of prostatic deposition correlated with the severity of cardiac deposition.

Lymph node metastases are classified based on size as macrometastases, micrometastases, or isolated tumour cells (ITCs). Micrometastases are associated with worse prognosis; however, optimal detection methods have yet to be established. The first objective was to determine if deeper levels and immunohistochemistry would detect micrometastases in patients with metastatic disease but negative lymph nodes. Five patients with pT3N0 colorectal adenocarcinoma who developed metastatic disease were identified. Three deeper haematoxylin and eosin (H&E) levels followed by pan-cytokeratin immunohistochemistry was performed on all lymph nodes. No micrometastases were detected; however, ITCs were seen by immunohistochemistry in three of five patients. Driven by these findings, the second objective was to determine if a single level stained for pan-cytokeratin would identify ITCs and if their presence was associated with an increased risk of disease recurrence. A cohort of eight patients with stage IIA (pT3N0M0) colorectal adenocarcinoma who developed distant metastasis was matched to eight control patients who remained disease-free over a 5-year period, and a single pan-cytokeratin stain was performed on all lymph nodes. ITCs were identified in six of eight patients that developed metastasis and in five of eight control patients (odds ratio=1.80; 95% confidence interval=0.21-15.41). In conclusion, three deeper levels and immunohistochemistry did not increase the yield of micrometastases in pT3N0 colorectal adenocarcinoma. While ITCs were readily identified by immunohistochemistry, their presence was not a significant predictor of distant recurrence. These findings do not support the routine use of deeper levels and immunohistochemistry for lymph node staging.</p>","PeriodicalId":19915,"journal":{"name":"Pathology","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144017052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
