Purpose. This study examines factors associated with outcomes following salvage radiation and systemic therapy for breast cancer patients who developed isolated locoregional recurrence (ILRR) after mastectomy alone, while focusing on the prognostic significance of constructed biologic subtype in this setting. Methods and Materials. 269 postmastectomy patients in total treated for ILRR were included. Cumulative incidence of locoregional control (LRC), distant metastasis (DM)-free survival (DMFS), disease-free survival (DFS), and overall survival (OS) were calculated using Kaplan-Meier method. For statistical analysis, biologic subtypes were constructed from hormonal receptors (Rec) and HER2, consisting of Rec+/HER2-, Rec+/HER2+, Rec-/HER2+, and Rec-/HER2-. The association of clinic-pathological and treatment-related parameters with outcomes was evaluated using a Cox regression model. Results. At a median follow-up of 65 months, 56 (20.8%) patients failed to secure LRC after radiotherapy, and 165 patients (61.3%) developed DM. Overall, the actuarial 5-year LRC, DMFS, DFS, and OS rate was 77.3%, 45.6%, 43.9%, and 66.8%, respectively. Multivariate analysis revealed that constructed biologic subtype represented the most significant prognostic factor for any outcome. Compared to patients with Rec+/HER2- disease, those with Rec-/HER2- had significantly poorer 5-year LRC (84.2% versus 58.3%, HR = 4.36, P < 0.001) and worse survivals including 5-year DMFS (63.0% versus 15.8%, HR = 4.28, P < 0.001), DFS (59.7% versus 13.6%, HR=3.92, P < 0.001), and OS (87.8% versus 22.3%, HR = 8.55, P < 0.001). Other factors associated with reduced LRC were no radical surgery and involved field irradiation alone, whereas factors associated with poor survivals included positive nodes at primary diagnosis and regional recurrence. Conclusions. Constructed biologic subtypes remained to be predictive of both disease control and survivals after salvage radiation for postmastectomy ILRR. Notably, Rec-/HER2- patients were demonstrated to be at high risk of locoregional failure and subsequent DM and tended to have worse survivals despite salvage therapies.

This study aims to investigate the prognostic significance of p-JNK in breast cancer patients receiving neoadjuvant chemotherapy (NACT) and analyze the relationship between anisomycin, p-JNK. A total of 104 breast cancer patients had NACT were enrolled in this study. The western blot and immunohistochemistry assays were used to determine the protein expressions of p-JNK in human breast cancer cell lines and patients’ cancer tissues. The chi-square test and Fisher’s exact test were adopted to gauge the associations between breast cancer and clinicopathological variables by p-JNK expression, whereas the univariate and multivariate Cox proportional hazards regression models were used to analyze the prognostic value of p-JNK expression. The Kaplan-Meier plots and the log-rank test were adopted to determine patients’ disease-free survival (DFS) and overall survival (OS). Findings indicated that the p-JNK expression had prognostic significance in univariate and multivariate Cox regression survival analyses. Results of log-rank methods showed that: (1) the mean DFS and OS times in patients with high p-JNK expression were significantly longer than those in patients with low p-JNK expression (χ2 = 5.908, P = 0.015 and χ2 = 6.593, P = 0.010, respectively). p-JNK expression is a significant prognostic factor that can effectively predict the survival in breast cancer patients receiving NACT. Treatment with the JNK agonist anisomycin can induce apoptosis, lead to increased p-JNK expression and decreased p-STAT3 expression. Moreover, the p-JNK expression was inversely correlated with p-STAT3 expression.

Abstract Purpose: Novel molecular characterization of breast cancer with cellular markers has allowed a new classification that offers prognostic value. This study investigates the prognostic value of the Bioscore among non-metastatic breast cancer patients with respect to disease free survival (DFS).Methods: This study included 317 patients with non-metastatic surgically treated breast cancer; they were identified in the period from January 2015 to December 2018 at Clinical Oncology Department of Assiut University Hospital. Many variables were used; pathologic stage (PS), T stage (T), nodal stage (N), grade (G), estrogen receptor (ER), progesterone receptors (PR), and human epidermal growth factor receptor (HER2) status. Univariate & two multivariate analyses were performed to identify which of these variables are associated with disease-free survival (DFS). Results: The only significant factors in the Univariate analysis were PS3, T2, T3, T4, N3, G2, G3, ER -ve, PR -ve, and HER2 –ve. The factors which were significant in the first multivariate analysis; PS3, G3, ER –ve, and in the second one were; T2, T4, N3, G3, and ER –ve. Two sets of models were built to determine the utility of combining variables. Models incorporating G and E status had the highest C-index (0.72) for T+N + G + ER in comparison with (0.69) for (PS+ G + ER) and the lowest AIC (953.01) for T + N + G + E and (966.9) for PS + G + E. Conclusions: This study confirms the prognostic significance of bioscore in non-metastatic breast cancer in concerning DFS.

CONTEXT: Patients receiving adjuvant chemotherapy for breast cancer have a tendency to gain weight. This tendency has determining factors not completely defined and an unknown prognostic impact. OBJECTIVE: To evaluate weight change during chemotherapy for breast cancer in a defined population and to identify its predisposing factors and possible prognostic significance. DESIGN: Observational, retrospective cohort study. SETTING: Private clinical oncology service. PARTICIPANTS: 106 consecutive patients with breast cancer treated between June 1994 and April 2000, who received neoadjuvant (n = 8), adjuvant (n = 74) or palliative (n = 24) chemotherapy. INTERVETION: Review of medical records and gathering of clinical information, including patients’ body weights before treatment and at follow-up reviews. MAIN MEASUREMENTS: Body weight change, expressed as percentage of body weight per month in treatment; role of clinical data in weight change; and influence of weight change in overall survival and disease-free survival. RESULTS: There was a mean increase of 0.50 ± 1.42% (p = 0.21) of body weight per month of treatment. We noted a negative correlation between metastatic disease and weight gain (r = -0.447, p < 0.0001). In the adjuvant and neoadjuvant therapy groups there was a mean weight gain of 0.91 ± 1.19 % (p < 0.00001) per month, whereas in the metastatic (palliative) group, we observed a mean loss of 0.52 ± 1.21% (p = 0.11) of body weight per month during the treatment. We did not observe any statistically significant correlation between weight changes and disease-free survival or overall survival. CONCLUSIONS: Women with breast cancer undergoing adjuvant or neoadjuvant chemotherapy gain weight, whereas metastatic cancer patients will probably lose weight during palliative chemotherapy. Further studies are needed in order to evaluate the prognostic significance of weight changes during chemotherapy.

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.

e12028 Background: iPS cell inducing factors (Oct3/4, Sox2, Klf4, c-Myc, and Nanog ) are reported that they appears not only in ES cells(Embryonic stem cell), but also in normal cell or carcinoma cell, including breast carcinoma. We evaluated the expression of iPS inducing factors in the human breast cancer specimen with immunohistochemistry, and analyze the relativity of the relapse and the prognosis after the operation. Methods: 200 cases of breast cancer that were performed the surgical operation in this department were examined. Expression of c-MYC, KLF4, NANOG, OCT4 and SOX2 were determined by immunohistochemistry using a tissue microarray. Results: The average of the patient's age was 55.2 years old (29 - 87), and the advanced breast cancers in stage II or more were 122 cases (61%). About the hormone receptor and the HER2 appearance, Hormone receptor positively (HR+) types were 162 cases (81%), 10 cases (5%) were HER2 positively (HER2+) type, and 28 cases (14%) were triple negative (TN) type. During the following period from operation, the relapse was found in 48 cases (24%), and 18 cases (9%) were died. The average of survival time after the operation was 80.7 months (4 - 162). Patients with strong expression of NANOG had significantly lower disease-free survival and overall survival rates than those with weak expression of NANOG (p=0.004 and P=0.033, respectively). In contrast, patients with strong expression of KLF4 had better disease-free survival (p=0.014). Conclusions: Strong expression of NANOG was an indicator of a poor prognosis for breast cancer patients, while KLF4 was a favorable prognostic indicator. Our results suggest that NANOG stimulates the growth and metastasis of breast cancer cells, whereas KLF4 inhibits these processes.

Purpose In 1996, we initiated the French multicenter phase III randomized trial to compare the effect on disease-free survival (DFS) of concurrent versus sequential chemotherapy (CT) and radiotherapy (RT) after breast-conserving surgery for stages I and II breast cancer. This report presents the clinical results with a median follow-up of 60 months. Patients and Methods Between February 1996 and April 2000, 716 patients were entered onto this trial. Adjuvant treatment began within 6 weeks after surgery. Sequential treatment of CT administered first followed by RT was compared with concurrent treatment of CT administered with RT. The CT regimen consisted of mitoxantrone (12 mg/m2), fluorouracil (500 mg/m2), and cyclophosphamide (500 mg/m2) on day 1, and it was repeated every 21 days for six courses. RT was delivered to the breast and, when indicated, to the regional lymphatics. Results There was no statistically significant difference in treatment in the 5-year DFS (80% in both groups; P = .83), locoregional recurrence-free survival (LRFS; 92% in sequential v 95% in concurrent; P = .76), metastasis-free survival (87% in sequential v 84% in concurrent; P = .55), or overall survival (90% in sequential v 91% in concurrent; P = .76). Nevertheless, in the node-positive subgroup, the 5-year LRFS was statistically better in the concurrent arm (97% in concurrent v 91% in sequential; P = .02), corresponding to a risk of locoregional recurrence decreased by 39% (hazard ratio, 0.61; 95% CI, 0.38 to 0.93). Conclusion This treatment protocol remains an appealing clinical option for many women with operable breast cancer at a high risk of recurrence. Combination treatments with new drugs for breast cancer are warranted.

Background. The impact of postmastectomy radiotherapy (PMRT) in patients receiving neoadjuvant chemotherapy (NAC) is unclear. The purpose of this study is to identify the patients who may benefit from PMRT. Methods. We retrospectively analysed patients with clinical stage II-III breast cancer who underwent NAC and modified radical mastectomy at our centre from 2007 to 2015. We investigated the relationship amongst locoregional recurrence rate (LRR), disease-free survival (DFS), and clinical pathological characters. Results. A total of 554 patients were analysed in this study. The median follow-up time was 65 months. Amongst the patients, 58 (10.5%) had locoregional recurrence, 138 (24.9%) had distant metastasis, and 72 (13.0%) patients died. The 5-year cumulative incidence of LRR and DFS was 9.2% and 74.2%, respectively. A total of 399 (72%) patients received PMRT and 155 (28%) did not. The 5-year LRR of the patients with PMRT (7.3% vs. 14.1%, P = 0.01 ) decreased significantly. We found that PMRT was an independent prognostic factor of LRR and DFS. Patients with the persistent involvement of 1–3 lymph nodes (ypN1) and more than 4 positive lymph nodes (ypN2-3) had a better outcome after PMRT than those without. However, the LRR and DFS of patients with negative lymph nodes at the time of surgery (ypN0) and who received PMRT showed no significant benefits. Amongst all patients with the three molecular subtypes of breast cancer, patients with triple-negative breast cancer had the highest pathological complete response rate but the worst prognosis ( P = 0.001 ). Conclusion. Results showed that PMRT significantly reduced the LRR of patients with clinical stage II-III breast cancer after receiving NAC and mastectomy. YpN0 patients derived no local control or survival benefit after receiving PMRT, whereas those with ypN1 and ypN2-3 could obviously benefit from PMRT.

Abstract Purpose: It is important to continually reevaluate the risk/benefit calculus of internal mammary node irradiation (IMNI) in the era of modern systemic therapy. We aimed to investigate the effect of IMNI on survival in node-positive breast cancer treated with mastectomy and anthracycline plus taxane-based chemotherapy.Methods and Materials: We analyzed 348 patients who underwent mastectomy and anthracycline plus taxane-based chemotherapy for node-positive breast cancer between January 2006 and December 2011. All patients received adjuvant radiotherapy with IMNI (n = 105, 30.2%) or without IMNI (n = 243, 69.8%). The benefit of IMNI for disease-free survival (DFS) and overall survival (OS) was evaluated using multivariate analysis and inverse probability of treatment weighting (IPTW) to adjust for unbalanced covariates between the groups.Results: After a median follow-up of 95 months, the 10-year locoregional recurrence-free survival rate, DFS, and OS in all patients were 94.8%, 77.4%, and 86.2%, respectively. The IPTW-adjusted hazard ratio (HR) for the association of IMNI (vs. no IMNI) with DFS and OS was 0.208 (95% confidence intervals (CI) 0.045–0.966) and 0.460 (95% CI, 0.220-0.962). In multivariate analysis, IMNI was a favorable factor for DFS (HR, 0.458; p = 0.021) and OS (HR 0.233, p = 0.018).Conclusions: IMNI was associated with improved DFS and OS in node-positive patients treated with mastectomy, post-mastectomy radiation therapy, and taxane-based chemotherapy, although the rate of locoregional recurrence was low.
