Web31 May 2024 · Historically, pathologists have judged responses to neoadjuvant treatment by counting viable cancer cells in subsequently resected tumor tissue. If those cells comprise less than 10% of the bulk tumor, the outcome is a major pathologic response (mPR); having no viable tumor cells is a pathologic complete response (pCR). Web18 Fluorodeoxyglucose-PET scan is gaining in importance for diagnostic purposes and for evaluating response to therapy [19,20]. A biopsy is necessary to establish the diagnosis. In most cases, a core needle biopsy is adequate to obtain diagnostic tissue, and the accuracy of core needle biopsies is excellent, with a high sensitivity and specificity [ 21 – 23 ].
