Ductal Carcinoma In Situ of the Breast: ‘Making the Punishment Fit the Crime’

To make the punishment fit the crime, you would want the decision of whether or not to use adjuvants to be informed by the degree of risk that the DCIS would recur. What factors can predict for an increased risk of recurrence, or more importantly, the risk of an invasive breast cancer occurring?

This study sought to evaluate the impact of RT for DCIS on mortality after SBC in a larger cohort. PATIENTS AND METHODS: Using the SEER database, 3,407 patients were identified who received breast-conserving therapy with or without RT for primary DCIS in 2000 through 2013 and subsequently developed a stage I-III invasive SBC within the same time period. Fine-Gray competing risk models were used to study the association between receipt of RT and mortality after SBC. RESULTS: Prior RT was found to be associated with higher rates of breast cancer-specific mortality (hazard ratio [HR], 1.70; 95% CI, 1.18-2.45; P=.005),...

This study sought to identify clinicopathological factors associated with upstaging and axillary metastasis in patients preoperatively diagnosed with DCIS by CNB.Materials and MethodsThis study identified 604 patients (cT1 ‐3N0M0) with preoperative diagnosis of pure DCIS by CNB who had undergone axillary evaluation from August 2006 to December 2015 at Fudan University Shanghai Cancer Center (FUSCC). Predictors of upstaging and axillary lymph nodes metastasis were analyzed, respectively.ResultsOf all 604 patients, 121 (20.03%) and 193 (31.95%) patients were upstaged to DCIS with microinvasion (DCISM) and invasive breast c...

ConclusionDCIS cases with duct abnormalities on ultrasound were investigated in this study. The important characteristics were as follows: (1) the distribution of ductal dilatation was focal or segmental, (2) solid parts were present in the dilated ducts, (3) the distribution of internal echoes was continuous or multiple, (4) the shape of solid echoes was broad-based and/or irregular, and (5) internal echoes were sometimes accompanied by echogenic foci. Accurate evaluation of these findings may be useful for diagnosing DCIS. Although the duct abnormalities are included in “ASSOCIATED FEATURES” in ACR BI-RADS AT...

AbstractPurposeThe future of non-operative management of DCIS relies on distinguishing lesions requiring treatment from those needing only active surveillance. More accurate preoperative staging and grading of DCIS would be helpful. We identified determinants of upstaging preoperative breast biopsies showing ductal carcinoma in situ (DCIS) to invasive breast cancer (IBC), or of upgrading them to higher-grade DCIS, following examination of the surgically excised specimen.MethodsWe studied all women with DCIS at preoperative biopsy in a large specialist cancer centre during 2000 –2014. Information from clinical records...

AbstractPurposeIt has been accepted that radiation therapy (RT) for ductal carcinoma in situ (DCIS) has no survival benefit despite increasing local control. However, a recent large database study reported a small but significant benefit. Using a Korean population-based large database, we examined the survival benefit of RT for DCIS after breast-conserving surgery (BCS) and analyzed which subgroup might derive benefit from it.MethodsData from 6038 female DCIS patients who underwent BCS with or without RT between 1993 and 2012 were included in this study. We used propensity score analysis to control for differences in basel...

ConclusionsThe presence of multiple foci of MI in DCIS is associated with higher 15-year risks of invasive LR after breast-conserving therapy compared to women with pure DCIS but treatment with whole breast and boost RT can mitigate this risk.

ConclusionFurther functional studies to decipher the role of IDH2 and its mechanism of action as a driver of BC progression and LVI are warranted.
