原始语种摘要: Abstract(#br)Lobular neoplasia (LN), invasive lobular breast cancer (ILBC) and related pleomorphic variants represent a distinct group of neoplastic mammary gland lesions. This study assessed the inter-observer agreement of histological grading in a series of ILBC and LN.(#br)54 cases (36x ILBC, 18x LN) were evaluated by 17 observers. 3978 classification calls on various histological features, including nuclear grade, proliferative activity (Ki67 immunohistochemistry, categorical scoring), histological grade and pleomorphism were obtained. Pairwise Cohen’s kappa values were calculated and compared between various features and different observer subsets with variable histomorphological experience.(#br)In ILBC, pairwise inter-observer agreement for histological grade ranged from poor to...
