Study Helps Gauge Long-term Risks for Women With DCIS Study Helps Gauge Long-term Risks for Women With DCIS

New research helps clarify the long-term risk for invasive breast cancer in women with ductal carcinoma (DCIS) in situ who opt for breast-conserving surgery alone or with radiotherapy.Reuters Health Information

ConclusionThe presence of breast cancer does not significantly increase the likelihood for upgrade at a separate site of ipsilateral concurrent ADH above contemporary reported upgrade rates of ADH alone (10 –30%). When considering breast conservation for breast cancer, omitting excision of the site of ADH can be considered when low-risk features are present.

This study aimed to assess the long-term risk of ipsilateral subsequent in situ and invasive lesions after a diagnosis of primary DCIS and the association with initial DCIS treatment.

CONCLUSIONS: RBS rate can be reduced by shaving of cavity margins. Current standards for RBS should not be made more stringent due to the existence of non-actionable risk factors. The value of RBS as a quality indicator should be scrutinzed. PMID: 32841804 [PubMed - as supplied by publisher]

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.

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...
