ConclusionsValidation of the SNUH BCS nomogram was not successful in the current study as much as its original publication. However, we could improve its predictive power by including surgeon-related factor. Before applying a published nomogram as a preoperative predictive model, we suggest each institution to validate the model and adjust it with surgeon-related factor. Addition of new factors to currently available nomograms holds promise for improving its applicability for breast cancer patients at the actual clinical level.

Conclusion: In every second patient who had first received a subcutaneous mastectomy, no tumor could be detected in the secondary operation despite a previous R1 status.

ConclusionsThe use of inversely planned IMRT-SIB as part of breast-conserving therapy results in optimal 5 ‑year tumor control and minor early toxicities.

AbstractPurpose of ReviewStandard options for the treatment of ductal carcinoma in situ (DCIS) include breast-conserving surgery (BCS) alone; BCS with radiotherapy or endocrine therapy, or both; and mastectomy. Survival is excellent with all options, but rates of local recurrence (LR) vary, as do quality-of-life measures. Here, we discuss treatment outcomes, risk factors for LR, and tools for risk estimation.Recent FindingsAfter BCS, radiotherapy reduces the risk of LR by half, and endocrine therapy reduces the risk by a third. Young age, inadequate margins, and greater volume of disease are associated with higher risk of ...

AbstractPurpose of ReviewMammographic screening and radiological surveillance for local management has led to an exponential increase in diagnosis of ductal carcinoma in situ (DCIS) with limited impact on breast cancer specific mortality. Since definitive diagnosis of DCIS requires histopathological examination increase in radiological surveillance has resulted in significant increase in breast biopsies. Pathological characteristics of DCIS include grade, necrosis, size, anatomy, margins of excision, estrogen, and progesterone receptor status, and these features are useful for both prognostication and prediction.Recent Fin...

AbstractPurpose of ReviewDuctal carcinoma in situ (DCIS) is commonly treated with radiotherapy as a part of breast-conserving therapy, though increasingly the use of routine radiation treatment is being questioned. The intent of this review is to summarize studies on the role of radiotherapy for DCIS, with an emphasis on more recent trials.Recent FindingsWhile older randomized clinical trials have established a local control benefit for adjuvant radiotherapy following breast-conserving surgery in all patients including those with low-risk DCIS, these and subsequent studies have failed to demonstrate any survival benefit. G...

Abstract We aimed to evaluate the surgical margin outcomes and re-excision rates in patients undergoing bracketed seed localization of biopsy-proven breast cancer detected on screening mammogram. After approval by our Institutional Review Board, we retrospectively identified patients who had undergone iodine-125 seed localized lumpectomy at our institution from January 2010 to June 2017 by one of two fellowship-trained breast surgeons. Of those patients, a subset of 25 patients were identified who had undergone bracketed seed localization, defined as two or more seeds used to delineate the radiographic borders of ...

In this study, we aimed to evaluate the prognostic significance of CTSV in DCIS. METHODS: CTSV protein expression was immunohistochemically assessed in a well-characterised and annotated cohort of DCIS comprising pure DCIS (n=776) and DCIS coexisting with IBC (n=239). CTSV expression was analysed in tumour cells and surrounding stroma, including its association with clinicopathological parameters and outcome. RESULTS: In pure DCIS, high CTSV expression was observed in 29% of epithelial tumour cells and 20% of surrounding stroma. High expression in both components was associated with features of poor prognosis inc...

Conclusion: The findings of this study are comparable to results in the literature on OPS and demonstrate that OPS is an attractive alternative to standard lumpectomy for Canadian general surgeons who treat breast cancer. PMID: 31995336 [PubMed - indexed for MEDLINE]
