Abstract Background Breast cancer diagnosed at younger age has aggressive biology being triple negative and high grade and associated with poor prognosis. Method Retrospectively data of 121 patients age 30 years or younger registered during the year 2008 was reviewed. Demographics studied were age at diagnosis, gender, pregnancy, or lactation associated, family history, histopathological diagnosis, stage of the disease, receptors, type of treatment, response, local recurrence, distant relapse, survival. Results One patient was male. Age range 20 -30 years, single patient had bilateral involvement. half 50.4%(n = 61) patients had locally advanced disease at presentation. Pregnancy/ lactation associated breast cancer was seen in 29.8%(n = 36). Most common stage was stage III (52.1%) & stage II (33.9%). IDC was the most common histology 94.2% (n = 114) Triple negative was most common molecular subtype present in 46.3%(56). After 5 years follow up, local recurrence was observed in 12.4%(n = 15), cancer related deaths were 42.1%(n = 51). Conclusions Breast cancer in very young has very aggressive tumor biology, needs aggressive treatment with surgery, chemotherapy, radiation therapy and hormonal therapy, furthermore there is need to identify possible environmental factors which may contribute in the rising incidence in this age group.

Purpose: Breast cancer diagnosed at a younger age has aggressive biology being triple negative and high grade and is associated with poor prognosis.Materials and Methods: Retrospectively data of 121 patients age 30 years or younger registered during the year 2008 were reviewed. Data were extracted from the cancer registry department of the institute. Demographics studied were the age at diagnosis, gender, pregnancy or lactation association, family history of breast cancer, histopathological diagnosis, and stage of the disease, receptors, type of treatment, response, local recurrence, distant relapse, and survival. Results: A total of 121 patients with age 30 years or less were included. An only a single patient was male. The age range was from 20 to 30 years; bilateral involvement was seen in a single patient. Almost half 50.4% (n = 61) patients had locally advanced disease at presentation. Pregnancy/lactation-associated breast cancer was seen in 29.8% (n = 36). The most common stage was Stage III (52.1%) and Stage II (33.9%). Invasive ductal carcinoma was the most common histology 94.2% (n = 114) of patients; triple negative was the most common molecular subtype present in 46.3% (n = 56). Chemotherapy was received by 92.6% (n = 112), 88.4% (n = 107) patients received radiation therapy. Modi ed radical mastectomy was performed in 57% (n = 69), breast conservation surgery in 35.5% (n = 43), follow- up period was 5 years, local recurrence was observed in 12.4% (n = 15) and cancer related deaths were 42.1% (n = 51). Conclusions: Breast cancer in very young has very aggressive tumour biology, needs aggressive treatment with surgery, chemotherapy, radiation therapy and hormonal therapy.

e13075 Background: Women in sub-Saharan African countries, as Angola, are experiencing an increasing burden of aggressive breast cancer. Breast cancer molecular subtypes may enable more accurate diagnoses and support therapeutic decisions, however several studies have suggested that African breast cancers are predominantly hormone receptor poor. We conduct a study, to correlate the clinical pathological profiles and molecular subtypes, according its surrogate immunohistochemistry (IHC) markers, of breast cancer in Luanda, Angola. Methods: From Jan. 2011 to Dec. 30, 2014, 179 consecutive cases of microscopically confirmed invasive breast carcinoma that were evaluable for histology and IHC (ER, PR, HER2, and Ki-67) were classified. However, 21.8% (n = 39) of cases were poorly preserved, therefore it was only possible to study IHC in 140 cases. Results: All patients were female, the median age was 47 years (24-84 years). Invasive ductal carcinoma was the most common type, 91.4% (n = 128), grade 2 (moderately differentiated) was prevalent, 67.1%. Most of the tumours were locally advanced, stage III 65% (n = 91) and stage IV 3.6% (n = 5). In 140 cases studied, 53.2% (n = 74 ) of malignancies were hormone receptors positive, whence 25.7% were luminal A like, 19.3% luminal B like/ HER2 negative, 7.9% luminal B like/HER2 positive, 15.7% HER2 positive and 31,4% were triple-negative. Conclusions: Woman with breast cancer in Luanda-Angola were caracterized by advance stage and younger age at diagnosis of disease. The two predominant molecular subtypes are triple negative and luminal A like. Therefore, determining the molecular subtype using surrogate IHC markers has important treatment and prognostic implications for Angola women with breast cancer.

Background: Management of locally advanced disease is a challenge. In women with significant residual disease after neoadjuvant therapy when subjected to surgery wounds cannot be closed primarily and require myo-cutaneous flap, Latismus dorsi being the easiest one. The purpose of this study is to look at the recurrence rate, time to recurrence and is surgery needed in this group of patients. Material and Methods: This is a hospital-based retrospective study conducted at Liaquat National Hospital and Medical College, Karachi. Pakistan. From 2006 to 2015, 15 patients with locally advanced breast cancer, who still had significant residual disease after adequate neo-adjuvant therapy that after Modified radical mastectomy wound could not be closed and latismus dorsi flap was used to close the defect. The age, histopathology report, margin of clearance, ER, PR, Her2 status and ki67 was noted. These patients were followed up to look for any local or systemic recurrence and time to recurrence and local or site of any systemic recurrence was recorded. Results: A total of 15 female patients with a mean age of 42.73±9.66 years with a mean follow up of 33.93±26.78 months were seen. In all patients, margins were histologically negative. Mean nodes removed and involved were 12.53±8.04 and 5.46±7.15 respectively. Meantime to recurrence was 16.00±14.92 months. In our study, recurrence was observed in 11 (73.3%) patients with 7(64 %) local and 4(36%) systemic recurrence. All 5 triple-negative and 4 patients stage IV 4 had local recurrence. Patients with poor prognostic markers like higher residual nodal involvement, large tumor size, higher Ki 67, aggressive tumor biology (triple-negative and HER2 Positive tumors) had a high and early recurrence. Conclusion: In patients with high residual tumor burden and aggressive biology has high chances of disease recurrence. Surgery in these patients should be offered to keep quality of life, disease biology and recurrence rate in mind.

Purpose: The aim of the study was to investigate the association between the molecular subtypes and patterns of relapse in breast cancer patients who had undergone curative surgery. Methods: We retrospectively evaluated 1,350 breast cancer patients with relapses after curative surgery between 1998 and 2012 from referral centers in Turkey. Patients were divided into 4 biological subtypes according to immunohistochemistry and grade: triple negative, HER2 overexpressing, luminal A and luminal B. Results: The percentages of patients with luminal A, luminal B, HER2-overexpressing, and triple-negative breast cancer were 32.9% (n = 444), 34.9% (n = 471), 12.0% (n = 162), and 20.2% (n = 273), respectively. The distribution of metastases differed among the subgroups: bone (66.2% and 53.9% in luminal A and B vs. 38.9% in HER2-overexpressing and 45.1% in triple negative, p < 0.001), liver (40.1% in HER2-overexpressing vs. 24.5% in luminal A, 33.5% in luminal B, and 27.5% in triple negative, p < 0.001), lung (41.4% in triple negative and 35.2% in HER2-overexpressing vs. 30.2% and 30.6% in luminal A and B, p = 0.008) and brain (25.3% in HER2-overexpressing and 23.1% in triple negative vs. 10.1% and 15.1% in luminal A and B, p < 0.001). Conclusions: Organ-specific metastasis may depend on the molecular subtype of breast cancer. Tailored strategies against distant metastasis concerning the molecular subtypes in breast cancer should be considered.

AbstractClaudin-low breast cancer represents an aggressive molecular subtype that is comprised of mostly triple-negative mammary tumor cells that possess stem cell-like and mesenchymal features. Little is known about the cellular origin and oncogenic drivers that promote claudin-low breast cancer. In this study, we show that persistent oncogenic RAS signaling causes highly metastatic triple-negative mammary tumors in mice. More importantly, the activation of endogenous mutant KRAS and expression of exogenous KRAS specifically in luminal epithelial cells in a continuous and differentiation stage-independent manner induces preneoplastic lesions that evolve into basal-like and claudin-low mammary cancers. Further investigations demonstrate that the continuous signaling of oncogenic RAS, as well as regulators of EMT, play a crucial role in the cellular plasticity and maintenance of the mesenchymal and stem cell characteristics of claudin-low mammary cancer cells.

The bromodomain-containing protein 4 (BRD4), a member of the bromodomain and extra-terminal domain (BET) protein family, has emerged in the last years as a promising molecular target in many tumors including breast cancer. The triple negative breast cancer (TNBC) represents the molecular subtype with the worst prognosis and a current therapeutic challenge, and TNBC cells have been reported to show a preferential sensitivity to BET inhibitors. Interestingly, BRD4 phosphorylation (pBRD4) was found as an alteration that confers resistance to BET inhibition and PP2A proposed as the phosphatase responsible to regulate pBRD4 levels. However, the potential clinical significance of pBRD4, as well as its potential correlation with the PP2A pathway in TNBC, remains to be investigated. Here, we evaluated the expression levels of pBRD4 in a series of 132 TNBC patients. We found high pBRD4 levels in 34.1% of cases (45/132), and this alteration was found to be associated with the development of patient recurrences (p = 0.007). Interestingly, BRD4 hyperphosphorylation predicted significantly shorter overall (p < 0.001) and event-free survival (p < 0.001). Moreover, multivariate analyses were performed to confirm its independent prognostic impact in our cohort. In conclusion, our findings show that BRD4 hyperphosphorylation is an alteration associated with PP2A inhibition that defines a subgroup of TNBC patients with unfavorable prognosis, suggesting the potential clinical and therapeutic usefulness of the PP2A/BRD4 axis as a novel molecular target to overcome resistance to treatments based on BRD4 inhibition.

TPS5600 Background: KIF18A is a mitotic kinesin motor protein that regulates chromosome positioning during cell division and is overexpressed in a subset of human cancers. TP53 mutant unstable aneuploid cancer cells with chromosomal instability (CIN) features are dependent on KIF18A motor activity to prevent lethal multipolar cell division. Preclinical data demonstrate that treatment with AMG 650; an oral, first in class, selective small molecule inhibitor of KIF18A may be safe and tolerable. We are conducting a first-in-human phase 1 study with AMG 650 in adult subjects with locally advanced or metastatic solid tumors with TP53MUT, triple negative breast cancer (TNBC), high grade serous ovarian cancer (HGSOC) or serous like endometrial cancers and other solid tumors. Methods: In this phase 1, multicentric, dose escalation and dose expansion study we evaluate the safety and tolerability of AMG 650 monotherapy in patients with advanced/metastatic solid tumors (NCT04293094). The main objective is to determine the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D) based on emerging safety, efficacy, and pharmacodynamics (PD) data prior to reaching the MTD. Key inclusion criteria include the presence of measurable disease and diagnosis of advanced/metastatic triple negative breast cancer (TNBC), high-grade serous ovarian cancer (HGSOC), serous-like endometrial cancer or other solid tumors with documented TP53 mutations. In the dose expansion phase, participants with locally advanced or metastatic TNBC or HGSOC will be treated with the preliminary RP2D identified from the dose exploration part of the study. Primary endpoints include the incidence of Dose Limiting Toxicities (DLTs),Treatment-Emergent Adverse Events (TEAEs), Serious Adverse Events (SAEs), Treatment-related Adverse Events and the evaluation of the number of participants who experience a clinically significant change from baseline in vital signs, electrocardiogram and laboratory tests parameters. Secondary endpoints include Objective Response Rate, Duration of Response, Progression-free Survival, Clinical Benefit Rate, Time to Response, Time to Progression, Overall Survival (OS), Maximum Plasma Concentration (Cmax) of AMG 650, Time to Maximum Plasma Concentration (Tmax) of AMG 650 as well as Area Under the Plasma Concentration-time Curve (AUC) Over the Dosing Interval for AMG 650. Continuous monitoring of toxicity is conducted. The study began enrolling pts in March 2020 and is ongoing.
