Local Recurrence Free Survival

1120 Background: After breast conserving surgery, radiotherapy leads to a better overall survival. In addition to whole breast radiotherapy (WBRT) a boost to the tumor bed leads to a better local control. The tumor bed boost is usually added after WBRT or can be done intraoperative (IORT). Belletti et al. (Clin Cancer Res., 2008) described positive effects, an antitumoral effect and modulation of microenvironment after IORT with 50kV x-rays. A matched pair analysis was performed to investigate the impact of IORT boost on overall survival compared to standard external beam boost. Methods: Between 2002 – 2009, 370 patients were treated for breast cancer with WBRT + boost (external beam (EBRT) boost n = 146, IORT boost n =224). A matched pair analysis (1:1 propensity score matching for age, TNM, grading, hormonal treatment and chemotherapy) for overall survival and local recurrence free survival could be done for 53 pairs. All patients underwent breast conserving surgery and WBRT with 46-50Gy. 53 patients received an EBRT boost with 16Gy (2Gy/fraction, dedicated linear accelerator) and 53 patients received an IORT boost with 20Gy (INTRABEAM system, 50kV x-rays). Median follow-up was 6 months (range, 1-77 months) for the EBRT boost patients and 56 months (range, 2-97 months) for IORT boost patients. Kaplan Meier estimates were performed for overall survival and local recurrence free survival. Results: IORT boost patients had a longer follow-up than EBRT boost patients. Despite the difference in follow-up times, there was a strong trend towards better overall survival after IORT boost (90.2% vs. 62.3%, p = 0.375). One local recurrence was present in each group (EBRT boost after 15 months, local recurrence free survival 95%; IORT boost after 12 months, local recurrence free survival 98.1%). Conclusions: IORT given as a boost seems to have a positive impact on overall survival in breast cancer patients after breast conserving surgery. To identify such an effect a prospective randomized trial should be conducted.

Purpose There is concern that women with multifocal ductal carcinoma in situ (DCIS; confined to one quadrant) who are treated with breast-conserving surgery face a high risk of local recurrence; therefore, many are treated with mastectomy. The objective of this study is to evaluate the significance of multifocality and the outcomes of women with multifocal DCIS treated with breast-conserving therapy. Methods The records of patients treated with breast-conserving surgery for DCIS between 1982 and 2000 were reviewed. Multivariate analyses were performed to evaluate the effects of multifocality and other prognostic factors on the rate of local recurrence. Results Of 615 cases of DCIS reviewed, 310 (41%) received breast-conserving surgery and 305 (40%) received breast-conserving surgery plus radiation (n = 260 with multifocality, n = 314 without multifocality, and n = 31 focality unreported). On multivariate analysis, multifocality (hazard ratio [HR] = 1.80; 95% CI, 1.15 to 2.80; P = .01), radiation treatment (HR = 0.46; 95% CI, 0.29 to 0.74; P = .001), margin width 4 mm or smaller (HR = 1.74; 95% CI, 1.03 to 2.92; P = .04), and high nuclear grade (HR = 1.65; 95% CI, 1.02 to 2.65; P = .04) were associated with risk of local recurrence. The detrimental effect of multifocality was limited to women who did not receive radiotherapy; the local recurrence–free survival rate at 10 years was 59% for women with multifocal disease and 80% for women without multifocality (P = .02). Among women treated with breast-conserving surgery plus radiation, there was no difference in 10-year local recurrence–free survival (80% v 87%; P = .35). There was no association between multifocality and the development of invasive recurrence. Conclusion Multifocality is a significant predictor of local recurrence in women who receive breast-conserving surgery for DCIS without radiotherapy; however, low recurrence rates can be achieved if adjuvant radiation is administered.

Abstract Background The TARGIT-A trial reported risk-adapted targeted intraoperative radiotherapy (TARGIT-IORT) during lumpectomy for breast cancer to be as effective as whole-breast external beam radiotherapy (EBRT). Here, we present further detailed analyses. Methods In total, 2298 women (≥45 years, invasive ductal carcinoma ≤3.5 cm, cN0–N1) were randomised. We investigated the impact of tumour size, grade, ER, PgR, HER2 and lymph node status on local recurrence-free survival, and of local recurrence on distant relapse and mortality. We analysed the predictive factors for recommending supplemental EBRT after TARGIT-IORT as part of the risk-adapted approach, using regression modelling. Non-breast cancer mortality was compared between TARGIT-IORT plus EBRT vs. EBRT. Results Local recurrence-free survival was no different between TARGIT-IORT and EBRT, in every tumour subgroup. Unlike in the EBRT arm, local recurrence in the TARGIT-IORT arm was not a predictor of a higher risk of distant relapse or death. Our new predictive tool for recommending supplemental EBRT after TARGIT-IORT is at https://targit.org.uk/addrt. Non-breast cancer mortality was significantly lower in the TARGIT-IORT arm, even when patients received supplemental EBRT, HR 0.38 (95% CI 0.17–0.88) P = 0.0091. Conclusion TARGIT-IORT is as effective as EBRT in all subgroups. Local recurrence after TARGIT-IORT, unlike after EBRT, has a good prognosis. TARGIT-IORT might have a beneficial abscopal effect.

Purpose: To compare outcomes for hypothetical cohorts of postmenopausal patients with estrogen receptor–positive tumors that are ≤ 2 cm in size, with pathologically uninvolved axillary nodes, treated with radiation therapy plus tamoxifen versus tamoxifen alone after breast-conserving surgery. Methods: A Markov model was used to simulate patients’ clinical course and estimate overall survival, recurrence-free survival, time with an intact breast, and death from breast cancer. Probabilities were derived from randomized trials and retrospective studies. Analyses were performed separately by age of diagnosis in 5-year increments from 50 to 80 years. Sensitivity analyses tested the stability of radiation benefit. Results: The modeled recurrence-free survival benefit of giving radiation therapy was 3.35 years for women who were 50 years of age at diagnosis, versus 0.61 years for women who were 80 years of age. In the 50-year-old cohort, radiation therapy resulted in additional 0.60 years survival, compared with 0.04 years among 80-year-olds. A 50-year-old woman who received radiation therapy plus tamoxifen was less likely to die from breast cancer than if she received tamoxifen alone (2.43% v 5.29%; relative-risk reduction, 54%). An 80-year-old woman had a 1.17% chance of dying from breast cancer if she received radiation therapy plus tamoxifen, versus 2.02% with tamoxifen alone (relative-risk reduction, 42%). Sensitivity analyses showed that the magnitude of benefit was strongly influenced by including unequal rates of developing distant disease after breast recurrence between the treatment arms and varying rates of local recurrence. Conclusion: The absolute and relative benefits of radiation therapy and individual patient preferences for different health states should be considered when selecting treatment.
