Objective: To compare the probabilities of local recurrence and distant metastasis between women with triple-negative and non- triple negative breast cancers. Methods: Medical and pathological records of breast cancer patients treated between the years 2002 and 2006 were reviewed. Results: There were 256 patients with complete data on estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER2) expression determinations. There were 54 patients (21%) with triple-negative (ER-, PR-, HER2 -) cancers. Triple-negative patients were more likely to have larger tumors with higher histologic grade. The median fallow-up time was 4 years. The probabilities of local and distant recurrence were similar between the two groups of patients. Only two factors were independently and significantly associated with overall recurrence: tumor stage and tumor size. Conclusion: Triple-negative breast cancer did not have a higher risk for both local recurrence and distant metastasis when compared with non-triple negative cancer.

e12616 Background: Neoadjuvant chemotherapy (NCT), Triple-negative breast cancer (TNBC) including anthracyclines and taxanes for early stages of TNBC, allows to achieve pathological complete response (pCR) in 25-36% of patients. Pathological complete response (pCR) significantly correlates with an increase in disease-free survival (DFS) and overall survival (OS). Methods: Randomized, monocentric trial was conducted in NN Petrov National Medical Research Center of Oncology from 2016 to 2019. 99 patients aged from 28 to 68 years with confirmed TNBC were included in trial: 96 had invasive ductal carcinoma G3, 3 - metaplastic cancer, negative BRCA mutations (a test for Founder mutations was performed).Patients were randomized in 3 groups, depending on the NCT regimen:1st subgroup (24 patients) - Eribulin in combination with Carboplatin AUC 5 x 4 cycles 2nd subgroup (37 patients) - Paclitaxel in combination with Carboplatin AUC 5 x 4 cycles 3rd subgroup (38 patients) –Carboplatin AUC5 + Doxorubicin + Paclitaxel x 6 cycles. Patients 1 and 2 subgroups in an adjuvant mode received 4 cycles of AC. Results: Clinical complete response (cCR) by physical examination (palpation) was achieved in 44 out of 99 patients (44.4%). Clinical complete response (cCR) by ultrasound and MG - in 27 (27.2%) patients. Miller-Payne V regression stage was achieved in 55 out of 99 cases (55.6%). In clinical cT1-T2 stage (n = 70), ypCR was achieved in 49 cases (70%), cT3-T4 (n = 29) ypCR in 6 patients (20.68%). Before NCT, 71 patients had status cN0-N1. Conversion to ypN0 occurred in 57 patients (80.2%). In 28 patients with cN2-N3 status, conversion to ypN0 occurred in 7 patients (25%). The median follow-up was 58 months. Progression was observed in 15.1% of patients, mortality – 6%. Local recurrence - 6 patients (6%), all patients were with residual tumor after NCT. Distant recurrence – 8 patients (8.1 %). Local recurrence rate and distant recurrence rate did not correlate with type of surgery (BCS or ME), but correlated with ypCR. Conclusions: NCT for TNBC is advisable both for locally advanced breast cancer and early breast cancer BC. De-escalation of BC surgery is possible in the future, especially in cT1-T2 stage patients (n = 70) where ypCR rate reaches 70%. It is planned to continue the trial with the vacuum aspiration biopsy of the tumor bed and SLNB after NCT.SLNB after NCT is advisable only in cN0-N1 group of patients (n = 71), since conversion to ypN0 was achieved in 57 patients - 80.2%.

Abstract Background: The local recurrence rate in triple negative breast cancer (TNBC) can be as high as 12%.The standard treatment for early-stage TNBC is breast conserving surgery (BCS), followed by postoperative radiotherapy with or without chemotherapy. However, detection of the local recurrence of the disease after radiotherapy is a major issue.Objective: The aim of this study was to investigate the role of dynamic and functional magnetic resonance imaging (MRI) during follow-up after BCS and radiotherapy with/without chemotherapy to differentiate between loco regional recurrence and postoperative fibrosis.Patients and methods: This prospective study was conducted at Oncology, Radiology, and Pathology Departments, Tanta University. It involved 50 patients with early-stage TNBC who were treated with BCS, followed by radiotherapy with/without chemotherapy. The suspected lesions were evaluated during the follow-up period by sonomammography. All patients were subjected to MRI, including conventional sequences, diffusion-weighted imaging (DWI), and dynamic post-contrast study. Results: Ten cases were confirmed as recurrent malignant lesions. After contrast administration, they all exhibited irregular T1 hypodense lesions of variable morphology with diffusion restriction and positive enhancement. Eight cases displayed a type III curve, while two showed a type II curve. Histopathological assessment was consistent with the MRI findings in all eight cases. The combination of the data produced by DWI-MRI and dynamic contrast enhanced (DCE)-MRI resulted in 100%sensitivity, 92.5% specificity, 90.9% positive predictive value, 100% negative predictive value, and 98% accuracy. Conclusion: Combination of DWI-MRI and DCE-MRI could have high diagnostic value for evaluating postoperative changes in patients with TNBC after BCS, followed by radiotherapy with/without chemotherapy.Trial Registrations: not trial to be registered

The objective: was to evaluate the efficacy of the first line chemotherapy in patients with metastatic triple negative breast cancer (TNBC). Materials and methods. Open randomized study was performed including 122 patients with metastatic TNBC. The efficacy and safety of the first line chemotherapy of regimens АТ (n=59) – group 1, patients received doxorubicine 60 мг/м2 and paclitaxel 175 мг/м2 and ТР (n=63) – group 2, patients received paclitaxel 175 мг/м2 and carboplatin AUC 5 were evaluated. Results. The median duration of response was 9.5 months (4.5–13.25 months) in patients received AT regimen and 8.5 months (4.7–12.25 months), in TP regimen; no statistically significant differences were observed, р=0.836. The median progression free survival was 7 months (95% CI 5–26 months) in group 1 and 7.5 months (95% CI 6–35 months) in group 2, p=0.85. Both chemotherapy regimens (AT and TP) had mild or moderate toxicity profiles (grade 1 or 2 in most patients). No significant difference in gastrointestinal toxicity was observed. The incidence of grade 3–4 neutropenia was higher in patients of group 2 (TP regimen): 42.8% versus 27% (р<0.05). Conclusions. Both regimens of chemotherapy (AT and TP) are appropriate to use in the first line setting in patients with metastatic TNBC. Key words: metastatic triple negative breast cancer, chemotherapy, progression free survival, chemotherapy toxicity.
