Background: Breast and thyroid cancers remain among the most common malignancies in women. In previous studies, the co-occurrence of thyroid and breast cancers has been reported. Objectives: The aim of this study was to evaluate and compare the risk and incidence of incidental thyroid nodules (ITNs) between patients with breast cancer and healthy controls, based on the Thyroid Imaging Reporting and Data System (TI-RADS). Methods: This case-control study was conducted on 140 patients with breast cancer and 140 cancer-free women in a similar age range. Thyroid ultrasonography (US) was performed before the onset of treatment. The risk stratification of thyroid nodules was based on the TI-RADS. Results: The mean age of the participants was not significantly different between the case (43.35 ± 7.85 years) and control (42.11 ± 3.69 years) groups (P = 0.094). Invasive ductal carcinoma was the most frequent type of breast cancer in the patients. Normal thyroid US findings were significantly less frequent in patients with breast cancer (35.7%) compared to the healthy controls (76.4%) (P = 0.001). On the other hand, thyroid nodules were more frequent in the patients and associated with a higher risk of malignancy (i.e., high TI-RADS scores) compared to healthy women (P = 0.001 and P = 0.001, respectively). Besides, patients with breast cancer showed more thyroid abnormalities in the US examinations. Conclusions: A higher frequency of ITN, with an elevated TI-RADS score, which raised the suspicion of malignancy, was seen in patients with breast cancer. Overall, patients with breast cancer may benefit from a regular thyroid US examination.

AbstractRecently, the American College of Radiology (ACR) proposed a Thyroid Imaging Reporting and Data System (TI-RADS) for thyroid nodules based on ultrasonographic features. It is important to validate this classification in different centres. The present study evaluated the risk of malignancy in solid nodules>1 cm using ACR TI-RADS. The risk of malignancy was defined including noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) and after its exclusion from malignant tumours. For the present study, the original images were revised, and each nodule was assigned to one of the TI-RADS levels proposed for solid nodules: TR3, TR4, or TR5. This risk of malignancy was significantly different for the three levels: 1.7%, 11.2%, and 60.6% for TR3, TR4, and TR5, respectively, when NIFTP was included, and 0.6%, 7.9%, and 60.2% for TR3, TR4, and TR5, respectively, when NIFTP was excluded from malignant tumours. The nodules corresponding to NIFTP were classified according to ACR as TR3 in 28.5% of cases, TR4 in 67.8%, and TR5 in only 3.5%. The nodules corresponding to cancer were classified according to ACR as TR3 in only 2.3% of cases, TR4 in 27%, and TR5 in 70.5%. In conclusion, this study shows the validity of the ACR TI-RADS for solid thyroid nodules, even after the exclusion of NIFTP from malignant tumours.

Although some therapies are available for regular breast cancers, there are very few options for triple-negative breast cancer (TNBC). Here, we demonstrated that serum level of IL-12p40 monomer (p40) was much higher in breast cancer patients than healthy controls. On the other hand, levels of IL-12, IL-23 and p40 homodimer (p402) were lower in serum of breast cancer patients as compared to healthy controls. Similarly, human TNBC cells produced greater level of p40 than p402. The level of p40 was also larger than p402 in serum of a patient-derived xenograft (PDX) mouse model. Accordingly, neutralization of p40 by p40 mAb induced death of human TNBC cells and tumor shrinkage in PDX mice. While investigating the mechanism, we found that neutralization of p40 led to upregulation of human CD4+IFNγ+ and CD8+IFNγ+ T cell populations, thereby increasing the level of human IFNγ and decreasing the level of human IL-10 in PDX mice. Finally, we demonstrated the infiltration of human cytotoxic T cells, switching of tumor-associated macrophage M2 (TAM2) to TAM1 and suppression of transforming growth factor β (TGFβ) in tumor tissues of p40 mAb-treated PDX mice. Our studies identify a possible new immunotherapy for TNBC in which p40 mAb inhibits tumor growth in PDX mice.

Increased microvessel density (MVD) values in breast cancer correlate with tumor growth and progression while mammaglobin (MGB) expression in tumor cells is associated with a favorable prognosis. We aim to evaluate and correlate MVD values with MGB expression in molecular types of breast cancer specimens and to determine their utility as prognostic biological markers. A number of 52 breast cancer specimens were included in the study. Specimens were processed for routine histopathological diagnosis followed by the molecular classification by means of estrogen (ER), progesterone (PR) and HER2 immunohistochemical reactions. After performing immunohistochemistry for CD34 and MGB, MVD evaluation was made using the �hot spot� method for each case and MGB was scored between 0 (negative) and +3 (strong positive) depending on the intensity and distribution of the staining. MGB expression in tumor cells and MVD mean values were extremely variable. The greatest MVD mean values were obtained in luminal B followed by HER2, luminal A and triple negative breast cancer (TNBC) (95.33, 69, 62, and 40, respectively). MGB expression in the tumor cells generally ranged from mild to weak and was strong only in a few invasive ductal carcinoma cases. In cases with TNBCs the expression of MGB in tumor cells was weak and focal or negative. This variability was noticed between the molecular types of breast cancers and even within the same molecular type. In a restricted number of cases, MGB positive tumors were associated with low MVD values while the negative cases were characterized by increased MVD mean values. The variable results we obtained regarding the correlation between MVD and MGB in breast cancer specimens may indicate a rather restricted use of MVD/MGB in estimating breast cancer patients� prognosis.

e11630 Introduction: Male breast cancer is very rare, representing only between 0.7% and 1% of all breast cancers, and only half of them are early stage cases. Objective: The present study has been designed with the aim of studying retrospectively the clinical onset and evolution of male invasive breast cancer patients (stages I and II) treated at IOHM between 1997 and 2008. Methods: The records of 3,000 breast cancer cases followed between 1997 and 2008 were searched, looking for male stage I and II breast cancer patients. A database was designed following the recommendations of the Directors of Surgical Pathology of the USA. The information registered encompassed: adjuvant treatments, recurrence date and date of final consultation or death. Results: Twelve pts were identified. Mean age (range)= 66 yo (50–89 yo). Tumoral type= Invasive Ductal Carcinoma 12 pt. Tumoral subtype= NOS 9 pt (75%) Apocrine 2 pt (17%) Micropapillar 1 pt (8%). Nottingham´s grade= Grade 2: 8 pt, Grade 3: 3 pt, N/A=1 pt. Stage= I= 6 pt, II=6 pt. ER (Positve= 9 pt, Negative=1 pt, N/A= 2 pt). PR (Positve= 8 pt, Negative= 2 pt, N/A=2 pt). Her2neu (0+= 3 pt, 1+= 3 pt, 2+= 2 pt, N/A= 4 pt). Surgery= Mastectomy= 11 pt, Lumpectomy 1= pt. Radiotherapy=5 pt. Adjuvance= No=2 pt, Hormonotherapy (HT)= 3 pt, Chemotherapy (CHT) = 3 pt, CHT+HT= 4 pt. Recurrence= Yes= 2 pt, No= 10 pt. Survival: Dead= 1 pt, Alive =11 pt. Mean Time To Progression= Stage I =66 months, Stage II =42 months. Global survival: Stage I =66 months, Stage II =52 months. Conclusions: 1. Twelve stage I and II male breast cancer patients were identified out of 3000 (0.4%) breast cancer cases diagnosed and followed in the past 10 years at the IOHM. 2. Mastectomy was the surgical procedure in 11 of the 12 cases 3. Ten pt underwent adjuvant treatment. 4. With a mean follow up time of 60 months, all stage I patients are alive and there were no recurrences. Two of the 6 stage II pts progressed and one died.

e11576 Background: Overexpression of human epidermal growth factor receptor 2 (HER2) occurring in about 20% of breast cancers is associated with increased risk of disease recurrence and worse prognosis. Despite the advent of therapies that target HER2, particularly, trastuzumab and lapatinib, that have altered the natural course of HER2-positive advanced breast cancer, tumor progression remains inevitable. New agents are in clinical development, but up to date there are limited data to direct the treatment of patients after lapatinib progression. Methods: We retrospectively searched for HER2-positive advanced breast cancer patients treated at our clinic, who received both trastuzumab-based therapy and lapatinib upon trastuzumab-progression in the metastatic setting. Thirty patients, all female, suffering from HER2-positive advanced breast cancer were identified. HER-2 positivity was assessed by immunohistochemistry (IHC 3+) or chromogenic in situ hybridization (CISH+). Results: Of the 30 patients, 83.3% had invasive ductal carcinoma; 60% had positive hormone receptor status, and 80% grade 3 tumours. Half of the patients received adjuvant trastuzumab. Median age was 57 years, range 37-79 years. 36.6% were switched to lapatinib after a median of three (range 2-6 lines) trastuzumab-based treatment lines. In 8 pts (37.5%) trastuzumab was re-started after lapatinib progression. In 7 of these patients, trastuzumab was combined with chemotherapy. Median progression free survival and overall survival in these patients was 4.75 and 8.87 months respectively. 3 patients received bevacizumab-based therapy upon lapatinib failure. Conclusions: Trastuzumab rechallenge after lapatinib progression may be active in a subgroup of heavily pre-treated patients. Clinical benefit of this strategy has to be balanced especially in limited resource settings with unavailability of novel agents or early phase clinical trials. As of now, there is no uniform accepted standard to define the optimal treatment approach of patients upon lapatinib progression showing the real need for new therapies in this population.

3135 Background: Saliva is non-invasively accessible and informative biological fluid which has high potential for the early diagnosis of various diseases. The aim of this study is to develop machine learning methods and to explore new salivary biomarkers to discriminate breast cancer patients from healthy controls. Methods: We conducted a comprehensive metabolite analysis of saliva samples obtained from 101 patients with invasive carcinoma (IC), 23 patients with ductal carcinoma in situ (DCIS) and 42 healthy controls, using capillary electrophoresis and liquid chromatography with mass spectrometry to quantify hundreds of hydrophilic metabolites. Saliva samples were collected under 9h fasting and were split into training and validation data. Conventional statistical analyses and artificial intelligence-based methods were used to access the discrimination abilities of the quantified metabolite. Multiple logistic regression (MLR) model and an alternative decision tree (ADTree)-based machine learning methods were used. The generalization abilities of these mathematical models were validated in various computational tests, such as cross-validation and resampling methods. Results: Among quantified 260 metabolites, amino acids and polyamines showed significantly elevated in saliva from breast cancer patients, e.g. spermine showed the highest area under the receiver operating characteristic curves (AUC) to discriminate IC from C; 0.766 (95% confidence interval [CI]; 0.671 – 0.840, P < 0.0001). These metabolites showed no significant difference between C and DICS, i.e., these metabolites were elevated only in the samples of IC. The MLR yielded higher AUC to discriminate IC from C; 0.790 (95% CI; 0.699 – 0.859, P < 0.0001). The ADTree with ensemble approach showed the best AUC; 0.912 (95% CI; 0.838 – 0.961, P < 0.0001). In the comparison of these metabolites in the analysis of each subtype, seven metabolites were significantly different between Luminal A-like and Luminal B-like while, but few metabolites were significantly different among the other subtypes. Conclusions: These data indicated the combination of salivary metabolomic profiles including polyamines showed potential ability to screening breast cancer in a non-invasive way.

Objective: Thyroid nodules with indeterminate cytology pose management challenges in clinical practice. The aim of this study was to determine the efficacy of ultrasound features in navigating clinical decision making in thyroid nodules with indeterminate cytology. Methods: We retrospectively reviewed ultrasound imaging from 186 adult patients with thyroid nodules and indeterminate cytology who underwent thyroidectomy at a quaternary hospital from 2010–2017. All nodules were classified based on the American Thyroid Association (ATA) and 2017 American College of Radiology Thyroid Imaging Reporting and Data System (ACR TI-RADS). Nodules were included if good quality pre-operative ultrasound imaging and surgical pathology were available. Results: A total of 202 thyroid nodules were included. The median age was 57 years; 82.8% were female. Risk of malignancy (ROM) in resected nodules with Bethesda 3 and 4 cytology was 19.4% and 30.3%, respectively. ATA high-suspicious and TI-RADS 5 nodules had high ROM, 100% in both systems for Bethesda 3 nodules; 66.7% and 50.0%, respectively, for Bethesda 4 nodules. For ATA very-low suspicious/TI-RADS 1 and 2, ROM was 0%. ROM in ATA low-suspicious/TI-RADS 3 nodules with Bethesda 3 cytology was lower (15.2% and 16.0%, respectively) than Bethesda 4 cytology (33.8% and 34.3%, respectively). ATA intermediate-suspicious/TI-RADS 4 nodules with Bethesda 4 cytology had a lower ROM (11.1% and 18.2%, respectively) than Bethesda 3 cytology (28.6 % and 31.6%, respectively). Conclusion: Using either the ATA or the TI-RADS system to risk-stratify nodules with indeterminate cytology may help clinicians plan better for additional diagnostic testing and treatment.

Abstract Background Breast cancer is a one of the malignant carcinomas partially caused by genetic risk factors. Germline BRCA1 gene mutations are reportedly associated with breast cancers. Identification of BRCA1 mutations greatly improves the preventive strategies and management of breast cancer. The aim of our study was to investigate the frequency of the deleterious BRCA1: p.Ile1845fs variant in breast carcinomas, as well as the correlation between p.Ile1845fs variant with clinicopathological parameters and clinical outcomes. Results A total of 23,481 clinically high-risk patients with breast cancer and 6489 healthy controls were recruited for p.Ile1845fs variant sequencing (either sanger or next generation sequencing). We identified 94 breast cancer patients (0.40%, 94/23481) as well as 11 healthy controls (0.17%, 11/6489) carried p.Ile1845fs variant. BRCA1: p.Ile1845fs variant showed a higher frequency in patients with TNBC molecular typing (20.21%, 19/94) and family history (37.23%, 35/94) compared with non-carriers (P = 3.62E-6 and 0.034, respectively). According to our data, we advanced the frequency of p.Ile1845fs variant and we confirmed that BRCA1: p.Ile1845fs variant was associated with increased risk of breast cancer (OR = 2.36, 95%CI = 1.26–4.89, P = 0.004). Conclusions BRCA1: p.Ile1845fs variant was a frequently pathogenic mutation in breast cancer in Han Chinese women and our data may be helpful for diagnosis and therapy of breast cancer.

Risk Of Malignancy

Objective: Management of thyroid nodules with Bethesda category III and IV cytology on fine needle aspiration (FNA) is challenging as they cannot be adequately classified as benign or malignant. Ultrasound (US) patterns have demonstrated the utility in evaluating the risk of malignancy (ROM) of Bethesda category III nodules. This study aims to evaluate the value of 3 well-established US grading systems (American Thyroid Association [ATA], Korean Thyroid Imaging Reporting and Data System [Korean-TIRADS], and The American College of Radiology Thyroid Imaging Reporting and Data System [ACR-TIRADS]) in determining ROM in Bethesda category IV nodules. Methods: Ninety-two patients with 92 surgically resected thyroid nodules who had Bethesda category IV cytology on FNA were identified. Nodule images were retrospectively graded using the 3 systems in a blinded manner. Associations between US risk category and malignant pathology for each system were analyzed. Results: Of the 92 nodules, 56 (61%) were benign and 36 (39%) were malignant. Forty-seven per cent of ATA high risk nodules, 53% of K-TIRADS category 5 nodules, and 50% of ACR-TIRADS category 5 nodules were malignant. The ATA high-risk category had 25% sensitivity, 82% specificity, 47% positive predictive value (PPV) for malignancy. K-TIRADS category 5 had 25% sensitivity, 85% specificity, 53% PPV for malignancy. ACR-TIRADS category 5 had 25% sensitivity, 84% specificity, 50% PPV for malignancy. None of the 3 grading systems yielded a statistically significant correlation between US risk category and the ROM ( P = .30, .72, .28). Conclusion: The ATA, Korean-TIRADS, and ACR-TIRADS classification systems are not helpful in stratifying ROM in patients with Bethesda category IV nodules. Clinicians should be cautious of using ultra-sound alone when deciding between therapeutic options for patients with Bethesda category IV thyroid nodules.
