Objective: To evaluate the possible associations between tumor pathological characteristics and reproductive factors in women with breast cancer, including method of child delivery. Materials and Methods: Patients diagnosed as breast cancer between January 2012 and April 2013 in Ankara University Hospitals who had at least one full term pregnancy were included. Data upon pathological prognostic features of tumors and reproductive history of patients were obtained from patient files. Results: 434 patients with breast cancer were included. Mean age at the time of breast cancer diagnosis was 49.2±10.7 years. History of at least one cesarean delivery was present in 17% of the patients (n=75). Axillary lymph node positivity was related to younger age at first full-term pregnancy (p=0.018), and higher number of parities (p=0.001) in estrogen receptor positive (ER+) breast cancer patients. Although extracapsular invasion was related to shorter time interval since last parity to cancer diagnosis in the whole population (p=0.029), this association disappeared when patients were categorized according to ER status. However, in ER+ patients, history of cesarean delivery was associated with extracapsular invasion (p=0.023). Also, our findings indicated that patients with history of cesarean delivery were diagnosed with breast cancer at younger ages, and after a shorter time interval since last parity (p<0.001). Tumor size (p=0.001), grade (p=0.046), axillary lymph node positivity (p=0.001), lymphovascular invasion (p<0.001), and shorter duration of time since last parity to breast cancer diagnosis (p=0.029) were indicators of metastatic disease. Conclusion: Our findings indicate that history of cesarean delivery may be associated with poor prognosis in ER+ patients with breast cancer.

Abstract Prior candidate gene studies have shown tumor suppressor DNA methylation in breast milk related with history of breast biopsy, an established risk factor for breast cancer. To further establish the utility of breast milk as a tissue-specific biospecimen for investigations of breast carcinogenesis, we measured genome-wide DNA methylation in breast milk from women with and without a diagnosis of breast cancer in two independent cohorts. DNA methylation was assessed using Illumina HumanMethylation450k in 87 breast milk samples. Through an epigenome-wide association study we explored CpG sites associated with a breast cancer diagnosis in the prospectively collected milk samples from the breast that would develop cancer compared with women without a diagnosis of breast cancer using linear mixed effects models adjusted for history of breast biopsy, age, RefFreeCellMix cell estimates, time of delivery, array chip and subject as random effect. We identified 58 differentially methylated CpG sites associated with a subsequent breast cancer diagnosis (q-value &lt;0.05). Nearly all CpG sites associated with a breast cancer diagnosis were hypomethylated in cases compared with controls and were enriched for CpG islands. In addition, inferred repeat element methylation was lower in breast milk DNA from cases compared to controls, and cases exhibited increased estimated epigenetic mitotic tick rate as well as DNA methylation age compared with controls. Breast milk has utility as a biospecimen for prospective assessment of disease risk, for understanding the underlying molecular basis of breast cancer risk factors and improving primary and secondary prevention of breast cancer.

5580 Background: The association between breast and uterine is well known. However, the effect that a prior breast cancer diagnosis may have on women with a new endometrial cancer diagnosis is less well described. The goal of our study was to determine the effect that a prior history of breast cancer would have on the outcome for women with type II uterine cancer. Methods: After obtaining IRB exemption, a retrospective chart review was performed. All women treated for uterine carcinoma between 1994 and 2007 were identified and we identified women with either uterine serous (UPSC) or clear cell carcinoma (UCCC) as the study group. The patients were then divided between those with and those without a prior breast cancer diagnosis. Patient demographics, cancer histologies, and stage of disease data were collected. Fisher's exact test and unpaired t test were used as appropriate. Progression-free (PFS) and overall survival (OS) were calculated using the Kaplan Meier method. Results: Approximately 1,083 patients were treated for uterine carcinoma during the study period of which 74 had pre-existing breast carcinoma (6.9%). One hundred and fifty women had USC and/or UCCC (13.8%) of whom 23 also had pre-existing breast carcinoma (13.3%). The women with breast cancer where older at the time of their uterine cancer diagnosis (77 y.o.) compared to those without breast cancer (68 y.o.) (p = 0.0089); were more likely to develop USC/UCCC (OR 2.56; 95% CI 1.47–4.44); and were more likely to be white compared to black (OR 4.6; 95% CI 1.74–11.99). At five years, there was no significant difference in PFS or OS between those women with and without a prior history of breast cancer. Conclusions: Women with a history of breast cancer have more the twice the likelihood of developing USC and/or UCCC. While having two primary malignancies can be devastating, our study indicated that women who developed a type II uterine cancer and also had a history of a prior breast cancer had the same outcomes as those women without a prior cancer diagnosis. This finding may help to allay patients’ fears about developing another malignancy and its impact on their prognosis. No significant financial relationships to disclose.

e12587 Background: Sarcoidosis is a multisystem granulomatous disease of unknown etiology. The pathogenesis of sarcoidosis is believed to be a result from a cellular immune reaction from exposure to occupational, environmental, or infectious elements that lead to the formation of noncaseating granulomas. Non-caseating granulomas are also present in cancer , and it is well known that the cancer cells carry neo-antigens, leading to a possible association between cancer and sarcoidosis. Several studies have shown an increased risk of breast cancer , in particular, in patients with sarcoidosis, but only a few studies have analyzed the incidence of sarcoidosis following breast cancer diagnosis. The present study aimed to identify patients with sarcoidosis following a diagnosis of breast cancer in our cohort of sarcoidosis. Methods: This is a retrospective case-series study between 2008-2018 of patients with sarcoidosis in the University of Miami Sarcoidosis Program. Sarcoidosis was defined per the World Association for Sarcoidosis and other Granulomatous Disorders guidelines. Breast cancer diagnosis was confirmed through pathology. We collected demographic data of age, gender, ethnicity and the time between diagnosis of breast cancer and sarcoidosis by chart review. Clincial data including clinical manifestations, laboratories, staging, and treatment were also collected. Results: Among 125 patients in our registry, 26 patients had a diagnosis of both cancer and sarcoidosis. In this, 12 (46%) developed sarcoidosis after the diagnosis of breast cancer and are the study population. Among them, 12(100%) were female. The most common ethnic group in the study population was European American with 8(67%) followed by African Americans 2(16.7%) and Hispanic 2(16.7%). Eight (67%) patients were treated with chemotherapy, 7(58%) with radiotherapy, of this, 6 (50%) received both. Mean (SD) age of onset of sarcoidosis was 61.9 ( 10.8) years . The mean time interval between breast cancer diagnosis and the onset of sarcoidosis was 5.58 ( 5.24) years ( (see Figure 1). Nine (75%) had pulmonary sarcoidosis and 3(25%) cardiac sarcoidosis. Among the subjects with pulmonary sarcoidosis 1(11.1%) had Stage 4, 4(44.4%) had Stage 2 and 4(44.4%) had stage 1. Conclusions: Our findings suggest sarcoidosis may be a paraneoplastic characteristic of breast cancer. The mechanism of granuloma development remains unclear. Cancer mediated immune dysregulation could be a potential contributing factor. Further studies are warranted to establish a definitive association.

Purpose The time interval between last childbirth and subsequent breast cancer diagnosis is emerging as an important prognostic factor for premenopausal women. Patients and Methods We studied, prospectively, 750 women diagnosed with primary invasive breast cancer before age 45 years who participated in the population-based Australian Breast Cancer Family Study (ABCFS). Results Median follow-up time was 4.9 years (range, 0.8 to 10.8 years). Compared with nulliparous women, women who gave birth within 2 years prior to diagnosis were more likely to have axillary node-positive (58% v 41%; P = .01), and estrogen receptor-negative (58% v 39%; P = .005) tumors. The unadjusted hazard ratios for death were 2.3 (95% CI, 1.3 to 3.8; P = .002), 1.7 (95% CI, 1.1 to 2.6; P = .03), and 0.9 (95% CI, 0.6 to 1.5; P = .8) for patients who gave birth less than 2 years, 2 to 5 years, and 5 or more years before diagnosis, respectively. After adjusting for tumor characteristics, these hazard ratios were reduced to 1.9 (95%CI, 1.1 to 3.2; P = .02), 1.3 (95% CI, 0.8 to 2.1; P = .3), and 0.9 (95%CI, 0.5 to 1.4; P = .5). Modeling showed that, compared with nulliparous women, the mortality hazard ratio in parous women was 1.9, decreasing by 8% (95%CI, 4% to 13%; P < .001) for each year between last birth and breast cancer diagnosis. Conclusion Proximity of last childbirth to subsequent breast cancer diagnosis is a predictor of mortality independent of histopathological tumor characteristics. Clinicians should be aware that women diagnosed with breast cancer within a few years following childbirth may have a worse outcome than that suggested solely by the standard histopathological prognostic factors of their cancer.

Contralateral axillary lymph node metastases (CAMs) in breast cancer patients are uncommon. CAM can be found at the time of primary breast cancer diagnosis or following prior treatment of breast cancer as a recurrence. This distinction may have important implications for disease staging and treatment selection. We report the case of a premenopausal woman with synchronous CAM. Despite extensive multimodality treatment, a recurrence was found 27 months after primary surgery. We reviewed the literature on histopathological tumor characteristics associated with CAM, lymphatic drainage of the breast to other sites than the ipsilateral axilla, and outcome of cases with CAM. This case contradicts current conceptions that CAM only develops from tumors with poor histopathological features. Emerging evidence shows that altered lymphatics play a central role in development of synchronous CAM. It is precisely this etiology that supports the concept that synchronous CAM occurs by lymphatic spread and not by hematogenous spread. Although controversial, treatment of synchronous CAM (without evidence of distant metastases) should therefore be of curative intent.

1541 Background: In our clinical practice at a tertiary cancer center, we have observed increased adenoma detection rate (ADR) in patients with breast cancer. Here, we describe ADR in patients with breast cancer to define the appropriate timing to initiate colonoscopy screening in these patients. Methods: We conducted a retrospective study of patients with breast cancer who underwent a colonoscopy after their diagnosis of breast cancer between 2000 and 2017. A control group ( n = 3295) comprised patients without any type of cancer who underwent their first screening colonoscopy between 2008 and 2017 was used in the logistic regression. Results: Of the 62,820 patients who had a diagnosis of breast cancer, 3304 were included. The mean age was 59 years. Regarding ADR, 1803 patients (55%) had adenomas. High-grade dysplasia was evident in 28% of polyps and invasive adenocarcinoma in 172 (5%). The median time from breast cancer diagnosis to adenoma detection was 3 years (IQR 1-6). The ADR was 21% in patients younger than 40 years ( n=63), 39% in patients between 40 and 50 years ( n=314), 54% in patients between 50 and 60 years ( n=1420), and 60% in patients older than 60 years ( n=1507). ADR in patients younger than 50 years of age who do not have a family history of colorectal cancer or a body mass index (BMI) higher than 30 kg/m2 was 26%. A subsequent colonoscopy was performed in 831 patients who had colonic adenoma in the initial colonoscopy. The ADR was 40% in patients who had a repeat colonoscopy within 3 years, 50% within 3-5 years, and 53% > 5 years. Multivariate logistic regression analyses revealed an increased risk of colon adenoma with older age, male sex, higher BMI, and personal history of breast cancer ( P<0.05). Conclusions: In patients with breast cancer, ADR was higher than that of patients without history of cancer. Notably, breast cancer was an independent risk factor for colon adenoma. In patients who are younger than 40 years of age, screening colonoscopy should be considered within five years of breast cancer diagnosis. Multivariate logistic regression: risk factors of adenoma.

Abc Transporter Genes

Breast cancer pharmacogenetics is increasingly being explored due to chemotherapy resistance among certain classes of patients. The ATP binding cassette (ABC) transporter genes have been previously implicated in breast cancer progression and drug response. In the present study, single nucleotide polymorphisms (SNPs) from the ABCC1, ABCC2, ABCB1, and ABCG2 genes were screened in breast cancer patients and healthy volunteers from the Jordanian-Arab population. Only the ABCB1 SNPs showed a significant association with BC in Jordanian-Arab patients, and the ABCB1 SNP rs2032582 exhibited a strong genotypic association with BC. With regard to the clinical characteristics of BC, the ABCC2 SNPs rs2273697 and rs717620 were found to be significantly associated with age at breast cancer diagnosis and breastfeeding status, while the ABCB1 SNP rs1045642 was significantly associated with age at breast cancer diagnosis. In terms of pathological characteristics, the ABCC1 SNP rs35628 and the ABCB1 SNP rs2032582 were significantly associated with tumor size, the ABCC2 SNP rs2273697 was significantly associated with estrogen receptor status, and the ABCG2 SNP rs2231142 was significantly associated with axillary lymph node status. In this current study, we assume that significant genetic variants within the ABC superfamily may increase the risk of breast cancer among Jordanian women. Furthermore, these variants might be responsible for worse BC prognosis.
