Influence of core needle biopsy number and core index on agreement between preoperative and postoperative histopathology
| Number of cores | Core index | ||||||

| In total, 113 patients were examined to find out whether the number of cores collected during the diagnosis of a suspicious lesion correlated with the likelihood of agreement between preoperative and postoperative histology. This was assessed by two methods: (1) a count of the number of cores and (2) an index of the amount of material examined by the pathologist (as described in Patients and methods). Mitoses, tubule formation, and nuclear pleomorphism were components of tumour grade. The p value was determined by binary logistic regression. | |||||||
