title: [Reproducibility of anatomo-pathological diagnoses: use of the kappa-test in histo-prognostic grading of soft tissue sarcomas in adults].
abstract: In pathology, reproducibility of lesional diagnostic and classification is not perfect, particularly when dealing with rare tumors like soft-tissue sarcomas, the classification of which is complex. Reproducibility among many independent observers can be well appreciated by kappa statistics, which take into account the agreement rate expected by chance only. A study of the reproducibility of histological classification and grading of 25 soft-tissue sarcomas by 15 pathologists showed that the agreement was better for the grading. A review of some other applications of kappa statistics in pathology reported in the literature is presented.
