3546 Background: The insulin-like growth factor type 1 receptor (IGF-1R) is involved in progression and sensitivity to systemic treatment of breast cancer. Moreover, targeted inhibition of IGF-1R is likely to be beneficial in systemic treatment. However, it is unknown how to select patients for IGF-1R targeted therapy. Therefore, we studied the relation between IGF-1R expression and prognosis in invasive ductal breast carcinomas. Methods: Immunohistochemistry was performed on tumor tissue of a consecutive cohort of 429 female patients treated for operable primary invasive ductal breast carcinoma. TMA sections were stained with antibodies against IGF1-R, insulin receptor (IR), ER, PR, HER-2, epidermal growth factor receptor (EGFR) and phosphorylated-Akt (p-Akt). Cytoplasmic and membranous IGF-1R staining were scored separately, as the relevance of IGF-1R cellular localization is yet unknown. Associations between IGF-1R expression with clinical and tumor characteristics were evaluated in a multivariate Cox regression model. To study in more detail the prognostic role of IGF-1R expression in triple negative invasive ductal carcinomas (TN IDCs), 51 TN IDCs from the series described above were combined with 64 TN IDCs from an independent dataset with similar patient and clinico-pathological characteristics. Results: Patients with tumors expressing both ER and cytoplasmic IGF-1R have a longer disease free survival (HR = 0.20; 95% CI 0.07 - 0.63; p-value = 0.006) and breast cancer specific survival (HR = 0.20, 95% CI 0.07 - 0.63, p-value = 0.002), independent of other known prognostic factors. Conversely, in the combined series of 105 TN IDCs, cytoplasmic IGF-1R expression was associated with a shorter disease free survival (HR = 2.29; 95% CI 1.08 - 4.48, p-value = 0.03). In a multivariate model including known prognostic factors, cytoplasmic IGF-1R expression was nearly significantly related to a shorter disease free survival (HR 2.06; 95% CI 0.95 - 4.47; p = 0.07). Conclusions: The favorable versus unfavorable association with prognosis of IGF-1R expression in ER positive versus TN IDCs may provide new opportunities to select patients for IGF-1R targeted therapy.

Background: Because of its high-risk biological features and lack of effective treatment options, triple-negative breast cancer (TNBC) has received greater clinical and experimental interest. Aim and objectives: The aim of this study was to compare and analyze the clinicopathological features, recurrence, metastasis, and prognosis of patients with TNBC and non-triple negative breast cancer (non-TNBC). Material and methods: This single hospital-based retrospective study was conducted on patients who were histopathologically diagnosed with breast cancer and subsequently treated from 2017 to 2018 at the Acharya Harihar Postgraduate Institute of Cancer. The clinical features and prognosis of TNBC and non-TNBC were compared. Results: This study comprised a total of 111 patients, with 36 (32.43%) being TNBC and 75 (67.56%) being non-TNBC. TNBC has 22 patients under the age of 40 (61.1%). Grade III tumors were seen in 47% of TNBC patients and 21% of non-TNBC patients (p-value = 0.05). The disease free survival (DFS) was determined to be 58 % for TNBC and 82% for non-TNBC groups, respectively (p-value = 0.05). These two groups had an overall survival rate (OS) of 72% and 92%, respectively (p-value = 0.05). Conclusion: When compared to non-TNBC, TNBC was related to high-grade malignancies, worse disease-free survival , and overall survival (OS) rates. Understanding the molecular features of TNBC, clarifying its mechanism at the molecular level, interpreting the gene expression profiles of TNBC, and studying and creating new therapeutic targets should be the focus of future research. To enhance the prognosis of TNBC patients, try to find a focused and effective therapy. Keywords: Breast cancer; survival; triple-negative breast cancer.

Background: Triple-negative breast cancer (TNBC) is an aggressive disease. Nomograms can predict prognosis of patients with TNBC. Methods: A total of 745 eligible TNBC patients were recruited and randomly divided into training and validation groups. Endpoints were disease-free survival and overall survival. Concordance index, area under the curve and calibration curves were used to analyze the predictive accuracy and discriminative ability of nomograms. Results: Based on the training cohort, neutrophil-to-lymphocyte ratio, positive lymph nodes, tumor size and tumor-infiltrating lymphocytes were used to construct a nomogram for disease-free survival. In addition, age was added to the overall survival nomogram. Conclusion: The current study developed and validated well-calibrated nomograms for predicting disease-free survival and overall survival in patients with TNBC.

e20711 Background: Breast cancer is the leading cause of cancer in women in Brazil and in the western world. Despite the high incidence of breast cancer in elderly women, there is no solid information regarding the real impact of the adjuvant systemic therapy in this population, considering the underrepresentation of patients with 65 years of age or older in cancer-treatment trials. Moreover, elderly patients may face some difficulties to receive adequate adjuvant systemic treatment in the routine clinical practice. Methods: Two hundred fifty eight patients with 65 years of age or older at the time of diagnosis of operable breast cancer and treated in our Institution from February 2000 to December 2005 were retrospectively studied. Clinical and pathological data were recorded as well as the type of adjuvant systemic therapy: hormonal therapy (HT), chemotherapy (CT) or both. We evaluated the disease free survival and overall survival and compared the results between the group of patients treated with HT only and the group of patients treated with both HT and CT. Results: Ninety five (37.5%) patients were stage I, 150 (58.1%) were stage II and 6 (2.3%) were stage III, while 5 (1.9%) patients were diagnosed with DCIS. Ductal carcinoma was the most frequent histological type (81%) and grade II were reported in the majority of patients (47.3%). Mostly of patients were hormonal sensible (74.4% were ER+ and 64% were PR+) and HER 2 negative (81.8%). One hundred seventy eight (69%) patients received any kind of adjuvant HT while 91 (35.3%) received any kind of adjuvant CT. There was no statistical difference between patients treated with HT when compared with the group of patients treat with HT and CT, regarding disease free survival and overall survival. However, a higher rate of high risk patients were observed in the group treated with both HT and CT. Conclusions: Despite the age, a considerable part of this elderly breast cancer patient's population has received adjuvant systemic treatment. Benefits from HT and/or CT may be considered in this group of patients. No significant financial relationships to disclose.
