Immunohistochemical detection of p53 and bcl-2 proteins in non-Hodgkin's lymphoma.

abstract：AIMS:There is evidence that four or five gastric cancer biopsies are required for accurate HER2 interpretation. However, the number of biopsies that need to be taken to reach this number of viable cancer biopsies is without evidence. This study aimed to address this gap by assessing the number of biopsies required to g...
