摘要: Aims:To compare the utility and reproducibility of tumour regression grade scoring systems during histopathological assessment rectal cancers resected after neoadjuvant (i.e. pre-operative) chemoradiotherapy. Methods results:? The features were assessed independently in 54 cancer resection specimens using three systems: Tumour Regression Grade (TRG), modified Rectal Cancer (m-RCRG) RCPath Dataset (RCPath) methods. Good interobserver agreement was achieved for all (? scores: TRG system 0.719, m-RCRG 0.734, 0.742). Both observers diagnosed complete little/no 11 cases (20% cases) four (11% cases), respectively. A mean 5.6 blocks/case taken lymph node yield 8.4/case. Conclusions:? All usable a diagnostic setting. clinical significance differing degrees is not yet universally agreed and, with this mind, provided optimum balance between applicability accurate recording low, moderate high regression, thus facilitating future clinicopathological studies outcome.
