Delay in radiotherapy is associated with an increased risk of disease recurrence in women with ductal carcinoma in situ

CONCLUSIONSA delay in RT>12 weeks is associated with a significantly higher risk of IBTR in women undergoing BCS for DCIS. Efforts should be made to avoid delays in starting RT to minimize the risk of disease recurrence. Cancer 2017. © 2017 American Cancer Society.

The objective of this study was to investigate the association of metabolic syndrome (MetS) with the risk of invasive breast cancer and molecular subtypes across race, menopause, and body mass index (BMI) groups. We examined the association of metabolic syndrome and its components with risk of invasive breast cancer among 94,555 female participants of the National Institute of Health-American Association of Retired Persons (NIH-AARP) Diet and Health Study, accounting for ductal carcinoma in situ as a competing risk. Cox proportional hazard regression with the Fine and Gray method was used to generate hazard ratios (HR) and...

This study analyzed data from women over 40 and compared the size of breast cancers at the time of diagnosis detected in the 1970s (before mammography became common) with the size of tumors detected between 2000 and 2002, when screening mammography was routine. Treatments and rates of death due to breast cancer 10 years after the diagnosis were also analyzed. The study found that: As more women underwent routine screening mammograms, more small breast cancers were detected. Many of these tumors were restricted to the ducts within the breast (called ductal carcinoma in situ), and even without treatment would never threaten...

ConclusionBreast density is an independent and significant risk factor for development of contralateral breast cancer. This risk factor should contribute to clinical decision making.

Abstract Comparing risk factor associations between invasive breast cancers and possible precursors may further our understanding of factors related to initiation versus progression. Accordingly, among 190,325 postmenopausal participants in the National Institutes of Health-AARP Diet and Health Study (1995-2011), we compared the association between risk factors and incident ductal carcinoma in situ (DCIS; n = 1,453) with that of risk factors and invasive ductal carcinomas (n = 7,525); in addition, we compared the association between risk factors and lobular carcinoma in situ (LCIS; n = 186) with that of risk facto...

Conclusion: Breast cancer survivors often experience GSM due to lack of estrogen. The worrisome lack of documentation of assessment or treatment for GSM in a large breast cancer survivorship practice reveals missed opportunities to improve quality of life. Dissemination of recent progress in the development of GSM assessment tools, patient handouts, and new treatments to providers who care for breast cancer survivors is needed to improve this process.

AbstractPurposeTo evaluate the association between levonorgestrel-releasing intrauterine system (LNG-IUS) use and breast cancer (BC) risk.MethodsA cohort of all Maccabi Healthcare Services (MHS) female members aged 40 –50 years between 1/2003 and 12/2013 was used to identify LNG-IUS users as “cases,” and 2 age-matched non-users as “controls.” Exclusion criteria included: prior BC diagnosis, prior (5 years pre-study) and subsequent treatment with other female hormones or prophylactic tamoxifen. Invasiv e tumors were characterized by treatments received (chemotherapy, hormonal therapy,...

Conclusions: Although further work is required to confirm our results and to clarify potential mechanisms, our findings suggest that exposure to residential outdoor light at night may contribute to invasive breast cancer risk. https://doi.org/10.1289/EHP935 Received: 08 August 2016 Revised: 17 March 2017 Accepted: 20 March 2017 Published: 17 August 2017 Address correspondence to P.
