Don't Delay Surgery for Very Early-Stage Breast Cancer, Study Suggests

THURSDAY, Oct. 24, 2019 -- Delaying surgery for a noninvasive breast cancer can have dire consequences, a new study shows. Longer delays in surgery for ductal carcinoma in situ (DCIS) breast cancer lead to a higher risk of invasive ductal carcinoma...

Here, we report blinded long-term follow-up results for the IBIS-II trial, which compared anastrozole with placebo...

This study was conducted in 263,788 women aged 40–69 years at enrolment into the UK Biobank population-based cohort. Information on demographic, reproductive and health factors was collected at baseline using computerized questionnaires, while incident DCIS was ascertained through linkage to UK cancer registries. Age-adjusted and multivariable hazard ratios were estimated using Cox proportional hazards models in the total sample and by menopausal status. During an average of 7 years of follow-up, 1,016 women developed DCIS. Multivariable analysis indicated that age, physical activity, height, family history of breast...

In this study, we examine the indications, complications, and long-term outcomes of therapeutic NSM. METHODS: From 2003 to 2016, women undergoing NSM for invasive cancer or ductal carcinoma in situ (DCIS) were identified from a prospectively maintained database. Patient and disease characteristics were compared by procedure year, while complications were compared by procedure year using generalized mixed-effects models accounting for a random surgeon effect. Overall survival and time to recurrence were examined. RESULTS: Of the 467 therapeutic NSMs, 337 (72%) were invasive cancer, 126 (27%) were DCIS, and 4 (1%) ...

CONCLUSIONS.—: Our study demonstrates that we handle transmasculine mastectomy specimens by examining 2.8 times more slides on average than for RMs, with a 2.5 times lower rate of significant pathologic findings. Prior family history of breast cancer or the use of androgen therapy before surgery in gender-affirming individuals did not increase the risk of identifying significant breast lesions. We recommend submitting 4 tissue blocks per mastectomy for individuals undergoing gender-affirming breast surgery. PMID: 31816268 [PubMed - as supplied by publisher]

ConclusionsThese results suggest heterogeneity by grade for breast cancer etiology. Identification of potential risk factor differences among low-grade and high-grade DCIS and IDBC may help to clarify associations, and ultimately, improve breast cancer risk prediction models.

ConclusionThere was a high agreement rate among readers when differentiating NME from mass lesions. The agreement rate was lower when assessing the distribution and internal enhancement pattern descriptors, but still substantial. The descriptors clustered ring enhancement and segmental distribution were significant predictors of malignancy.Key Points• Non-mass enhancement is a common morphological feature of non-invasive breast cancer (DCIS) in MRI. Differentiation between potentially malignant and benign changes may be very challenging.• Since clustered ring enhancement and segmental distribution are both signif...

While there has been some controversy over when women should start getting mammograms, all experts agree that screening is an important first step in detecting breast cancers and treating them early. But for some women, that’s not enough. For the approximately 40% of women with dense breast tissue, and especially the 10% with extremely dense tissue, cancer cells are harder to detect, since the denser tissue can mask small growths. In addition, dense breast tissue itself is also a risk factor for developing cancer. There’s been debate among experts over whether these women should have additional screening, on to...
