Abstract Background Estimates of contralateral breast cancer (CBC) risk in the modern treatment era by year of diagnosis and characteristics of the first breast cancer are needed to assess the impact of recent advances in breast cancer treatment and inform clinical decision making. Methods We examined CBC risk among 419,818 women (age 30–84 years) who were diagnosed with a first unilateral invasive breast cancer and survived ≥ 1 year in the US Surveillance, Epidemiology, and End Results program cancer registries from 1992 to 2015 (follow-up through 2016). CBC was defined as a second invasive breast cancer in the contralateral breast ≥ 12 months after the first breast cancer. We estimated standardized incidence ratios (SIRs) of CBC by year of diagnosis, age at diagnosis, and tumor characteristics for the first breast cancer. Cumulative incidence of CBC was calculated for women diagnosed with a first breast cancer in the recent treatment era (2004–2015, follow-up through 2016). Results Over a median follow-up of 8 years (range 1–25 years), 12,986 breast cancer patients developed CBC. Overall, breast cancer patients had approximately twice the risk of developing cancer in the contralateral breast when compared to that expected in the general population (SIR = 2.21, 95% CI = 2.17–2.25). SIRs for CBC declined by year of first diagnosis, irrespective of age at diagnosis and estrogen receptor (ER) status (p-trends < 0.001), but the strongest decline was after an ER-positive tumor. The 5-year cumulative incidence of CBC ranged from 1.01% (95% CI = 0.90–1.14%) in younger women (age < 50 years) with a first ER-positive tumor to 1.89% (95% CI = 1.61–2.21%) in younger women with a first ER-negative tumor. Conclusion Declines in CBC risk are consistent with continued advances in breast cancer treatment. The updated estimates of cumulative incidence inform breast cancer patients and clinicians on the risk of CBC and may help guide treatment decisions.

Background and Objectives: This study aimed to evaluate the effect of a BRCA mutation on survival and failure patterns, focusing on the risk of ipsilateral recurrence and contralateral breast cancer in patients. Materials and Methods: We retrospectively reviewed medical records of 300 patients with breast cancer who underwent genetic screening for BRCA1/2 genes and were treated at Samsung Medical Center between 1 January 2000 and 31 December 2010. Ultimately, clinical outcomes of 273 patients were analyzed. Results: The median follow-up duration was 102 months (range, 1 to 220 months). Patients with BRCA1/2-mutated tumors had a shorter 10-year disease-free survival (DFS) rate compared to those with non-mutated tumors (62.8% vs. 80.0%, p = 0.02). Regarding failure patterns, patients with BRCA1/2-mutated tumors showed a higher incidence of contralateral breast cancer than those with non-mutated tumors (BRCA1/2 non-mutated vs. mutated tumors: 4.9% vs. 26.0%, p < 0.001). BRCA mutation status remained a significant prognostic factor for contralateral breast recurrence-free survival (HR: 4.155; 95% CI: 1.789–9.652; p = 0.001). Korean patients with a BRCA mutation showed inferior DFS compared to those without a BRCA mutation. Conclusions: BRCA mutation status is a strong predictor of recurrence in contralateral breast cancer. Strategies such as prophylactic treatment and active surveillance should be discussed with breast cancer patients who have a BRCA mutation.

PURPOSE: To determine the risk of second malignancies after lumpectomy and radiation therapy (LRT), and to compare it with that in a similar cohort of early-stage breast cancer patients undergoing mastectomy without radiation (MAST). PATIENTS AND METHODS: Between January 1970 and December 1990, 1,029 breast cancer patients at our institution underwent LRT. A cohort of 1,387 breast cancer patients who underwent surgical treatment by mastectomy (MAST), and who did not receive postoperative radiation during the same time period, served as a comparison group. Second malignancies were categorized as contralateral breast versus nonbreast. In the cohort of patients undergoing LRT, a detailed analysis was carried out with respect to age, disease stage, smoking history, radiation therapy technique, dose, the use of chemotherapy or hormone therapy, and other clinical and/or pathologic characteristics. RESULTS: As of March 1999, the median follow-up was 14.6 years for the LRT group and 16 years for the MAST group. The 15-year risk of any second malignancy was nearly identical for both cohorts (17.5% v 19%, respectively). The second breast malignancy rate at 15 years was 10% for both the MAST and LRT groups. The 15-year risk of a second nonbreast malignancy was 11% for the LRT and 10% for the MAST group. In the subset of patients 45 years of age or younger at the time of treatment, the second breast and nonbreast malignancy rates at 15 years were 10% and 5% for patients undergoing LRT versus 7% and 4% for patients undergoing mastectomy (P, not statistically significant). In the detailed analysis of LRT patients, second lung malignancies were associated with a history of tobacco use. There were fewer contralateral breast tumors in patients undergoing adjuvant hormone therapy, although this did not reach statistical significance. The adjuvant use of chemotherapy did not significantly affect the risk of second malignancies. CONCLUSION: There seems to be no increased risk of second malignancies in patients undergoing LRT using modern techniques, compared with MAST. Continued monitoring of these patient cohorts will be required in order to document that these findings are maintained with even longer follow-up periods. With nearly 15 years median follow-up periods, however, these data should be reassuring to women who are considering LRT as a treatment option.

e11509 Background: Distant spread from breast cancer is commonly found in bones, lungs, liver, and central nervous system. However, peritoneal involvement is unusual and unexpected. The aim of the study was to perform a comprehensive analysis of breast cancer patients with peritoneal metastases. Methods: Twenty-one (0.9% of the cohort) breast cancer patients with peritoneal metastases were detected out of a database of 2,219 breast cancer patients treated in Hacettepe University Medical Oncology Department. Clinical characteristics, follow up times and survival rates were analyzed. Results: The mean age of the 21 patients at the time of peritoneal metastasis was 56 years (38-71). 12 (57.1%) patients were post-menopausal, 6 (28.6%) patients were pre-menopausal. Numbers of deceased patients were 7 (33.3%). Seven (33.3%) patients’ histological subtypes were invasive ductal carcinoma (IDC), five (23.8%) patients’ were invasive lobular carcinoma (ILC) and three (14.3%) patients’ were mixed (IDC and ILC). Numbers of luminal A patients were 8 (38.1%), luminal B were 5 (23.8%), triple negative were 2 (9.5%). There was no Her-2 overexpressing patient and numbers of unknown molecular subtype patients were 6 (28.6%). The median follow up times after peritoneal disease in patients deceased and living were 9.3 (range: 0.4-23.3) months and 15.6 (range: 0.3-40.4) months, respectively. Median follow up time after peritoneal metastasis of ER positive patients was 13.7 months, and it was longer than ER negative patients (4.4 months). Six months and one year survival rates after peritoneal metastasis were 83.3% and 73.3%, respectively. Disease free, progression free and overall survival data could not be obtained due to inadequate number of events. Conclusions: Peritoneal metastasis of breast cancer is very rare and median survival time is controversial in literature. Despite of a small cohort, we found the patients’ follow up times longer than reported before. Especially, ER positive patients have longer survival time than ER negative, and this result highlights the importance of hormonotherapies.

The present study investigated whether tumor markers such as cell proliferation and steroid receptor status, which have been shown to have relevance for important endpoints (relapse-free and overall survival), can also predict axillary disease in elderly patients with breast cancer. We evaluated 351 consecutive elderly women with breast cancer ≥70 years of age with estrogen receptor (ER)-positive tumors with no palpable axillary nodes, for whom information on cell proliferation determined by the 3H-thymidine labeling index (TLI) and progesterone receptor (PgR) was available. Patients underwent quadrantectomy (70.1%) or quadrantectomy plus radiotherapy (29.9%) without axillary node dissection, followed by adjuvant tamoxifen for at least 2 years. Univariable (cumulative incidence curves) and multivariable analyses (Fine and Gray models) were carried out. After a median follow-up of 16 years, ipsilateral axillary relapse was not related to PgR status but was strongly associated with tumor cell proliferation in both small (pT1) and large (pT2-4b) tumors. Axillary relapse cumulative incidence increased from 1% in patients with low-TLI (≤3%), PgR-positive and pT1 tumors to a maximum of 20% in patients with high-TLI, PgR-negative and pT2-4b tumors. Tumor cell proliferation, determined by TLI at primary surgery, is an important predictor of axillary relapse in elderly ER-positive breast cancer patients and could help to identify patients who should undergo axillary surgery.

Mammographic Finding

Forty-nine (5%) of 956 women referred for follow-up imaging after breast cancer treatment had a malignancy in both breasts. The mammograms and ultrasonograms or US reports, and histologic slides or pathologic reports of 31 of these patients were reviewed. Mammography was more sensitive than clinical examination or US in detecting contralateral breast cancer, the sensitivity of mammography being 81%. Thirty-nine percent of the contralateral cancers were nonpalpable, and all were first detected at mammography. No cancers were depicted by US alone. US provided complementary information about palpable masses in 50% of the cases in which the mammographic finding was difficult to interpret. The mammographic appearance and the difficulties in detecting a contralateral cancer were similar to those known to be characteristic for first primaries. Distinguishing a new primary from a metastasis from the first breast cancer was not always possible by means of mammography or US.

Abstract Purpose Breast cancer is increasing around the globe, including Asia. We aimed to examine the survival and risk of contralateral breast cancer (CBC) in Asian breast cancer patients with BRCA mutations. MethodsA total of 128 breast cancer patients with germline BRCA mutations and 4,754 control breast cancer patients were enrolled. Data on clinical pathologic characteristics, survival and CBC were collected from the medical record. The rates of survival and CBC were estimated by Kaplan-Meier method. Results The mean age of onset in BRCA mutation carriers was significantly younger than control patients (BRCA vs. Non-BRCA: 43.9 vs. 53.2 years-old). BRCA mutation carriers had a higher proportion of triple-negative breast cancer (TNBC) (52%) than control patients (12%, p<0.001). The risk of CBC was significantly higher in BRCA mutation patients than in control cases (hazard ratio (HR) = 3.95, 95% CI 2.71-5.75); when stratified by genotype, the HRs (95%CI) were 4.84 (3.00-7.82) for BRCA1 and 3.13 (1.78-5.49) for BRCA2 carriers, respectively. Moreover, BRCA1 mutation patients with triple-negative breast cancer (TNBC) as their first breast cancer had the highest risk of CBC (HR = 5.55, 95% CI 3.29-9.34). However, we did not observe any differences in relapse-free survival and overall survival between mutation carriers and control patients. ConclusionOur study suggest that BRCA patients had a significantly higher risk of developing CBC, particularly for BRCA1 mutation carriers with TNBC as the first breast cancer.
