Clinical practice guidelines for intraductal papilloma: Chinese Society of breast surgery (CSBrS) practice guidelines 2021

To standardize the diagnosis and treatment of intraductal papilloma of the breast and provide a reference for the clinical work of breast specialists, Chinese Society of Breast Surgery has determined the key clinical issues of the clinical practice guidelines for intraductal papilloma of the breast through a literature search and expert discussion. The relevant evidence was evaluated with reference to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system, and the Clinical Practice Guidelines for Intraductal Papilloma: Chinese Society of Breast Surgery (CSBrS) practice guidelines 2021 was formulated to provide a reference for the clinical work of breast surgeons in China. According to its anatomical location and histological features, intraductal papilloma can be divided into the central and peripheral type. For this type of tumor, imaging examination combined with core needle biopsy/vacuum-assisted breast biopsy (CNB/VABB) is recommended to obtain a histopathological diagnosis. Because galactography lacks high-level research evidence,[18] the panel does not recommend it as a diagnostic method.
