ConclusionsThe results of this study showed that lung volume changes were not a cause for concern in breast cancer patients. There are three reasons to support this conclusion. Lung volume changes and percentage reductions in LVP for each Gy increase of MLD and each percentage increase of V20 in each lobe were small; patients were asymptomatic during the follow-up period; and LVP showed partial improvements after 6 months.

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...

We examined the hazard function adjusted for adherence to surveillance mammography to examine variations in LR risk and the effect of RT over time.MethodsCrude hazard estimates for the development of LR in a population cohort of DCIS treated by BCS  ± RT were computed. Multivariable extended Cox models and hazard plots were used to examine the association between receipt of RT and risk of each outcome adjusted for baseline covariates and adherence to mammography.ResultsPopulation cohort includes 3262 women treated by BCS; 1635 received RT. Median follow-up was 13  years. LR developed in 364 women ...

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.

Authors: Bae SJ, Ahn SG, Yoon CI, Yang BS, Lee HW, Son EJ, Jeong J Abstract Purpose: We evaluated the clinical value of breast magnetic resonance imaging (MRI) in patients who underwent breast-conserving surgery (BCS). The degree of correlation between pathology size and MRI or ultrasonography (US) size was compared based on breast cancer subtypes. In addition, we investigated the positive margin rates. Methods: Patients with invasive breast cancer who underwent preoperative breast MRI and US between 2011 and 2016 were included in the study. Lin's concordance correlation coefficient was used to measure the corr...

Conclusion: Despite the low pCR rate, the tumor response and BCS conversion rates after NAC of luminal HER2- breast cancer were similar to those of other subtypes. NAC has the potential benefit of reducing the size of breast cancer, thereby increasing the BCS conversion rate in luminal HER2- breast cancer. PMID: 31598341 [PubMed]

Soon after publication of the results of NSABP-04 and NSABP-06 trials [1,2], an increasing proportion of women with early stage breast cancer received breast conserving therapy (BCT), including breast conserving surgery and adjuvant whole breast irradiation, in lieu of a mastectomy. Subsequent to these trials, BCT became the preferred treatment approach after the National Institutes of Health (NIH) Consensus conference in 1990 [3]. However, recent studies have shown a rising rate of mastectomies in patients who are eligible for BCT.

ConclusionsBreast conservation may be considered a safe alternative in the surgical treatment of MBC. Future research should focus on better standardization of local therapy for MBC and improved reporting of outcomes.

ConclusionsGuidelines from Cancer Australia may impact clinician behaviour. The influence of the individual radiation oncologist remains paramount, and their practice is affected by their immediate colleagues. Subsequent analysis of hypofractionation rates after presentation of these data has resulted in a significant increase in its use.
