Abstract

Background The natural history of lobular carcinoma in-situ (LCIS) suggests that women are at increased risk of subsequent invasive breast cancer. Questions of effective management for women with this lesion have led to the need for evidence-based guidance and, in particular, guidance regarding management after LCIS is found at core needle biopsy (CNB). Methods A systematic review was conducted to determine the most appropriate management for women with LCIS found at CNB. A comprehensive search of the scientific literature was conducted to identify the literature pertaining to this population. Critical appraisal of the literature, data extraction and a narrative synthesis of the results were conducted. The outcome of interest was upgrade of diagnosis to invasive breast cancer or ductal carcinoma in-situ (DCIS). Results Sparse data, with limited generalisability and considerable uncertainty, are available for women with LCIS at CNB. Nine studies were identified that met pre-specified inclusion criteria. The reported estimates of upgrade of diagnosis from LCIS to invasive breast cancer or DCIS ranged from 2% to 25%. The body of evidence was limited by its retrospective nature, risk of selection bias and poor generalisability to all women with LCIS at CNB. Further, higher quality research is required to determine the best approach for women with LCIS at CNB with any certainty.
