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.

230 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: 66 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 of tissue microarray. Results: The average of the patient’s age was 56.4 years old (36-87), and the advanced breast cancers in stage 2 or more were 44 cases (66%). About the hormone receptor and the HER2 appearance, hormone receptor-positive (HR+) types were 53 cases (80%), 6 cases (9%) were HER2-positive (HER2+) type, and 7 cases (11%) were triple-negative (TN) type. During the following period from operation, the relapse was found in 16 cases (24%), and six cases (9%) died. The average of survival time after the operation was 80.7 months (4-162). Patients with high expression group of NANOG had poor disease-free survival (p = 0.045) and overall survival (p < 0.0001) than those with low expression group. On the other hand, patients with high expression group of KLF4 had better disease-free survival (p = 0.028) than low expression group. Conclusions: High expression of NANOG was prognostic factor, but KLF4 was inversely related to prognosis in breast cancer patients. It was suggested that NANOG increased the growth and metastatic activities of breast cancer cells, while KLF4 decreased these activities.

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.

PURPOSE: To determine the incidence and prognostic significance of eradication of cytologically proven axillary lymph node metastases in breast cancer patients treated with primary chemotherapy. PATIENTS AND METHODS: Between January 1985 and December 1994, 152 breast cancer patients with invasive T1 to T3 tumors and axillary metastases cytologically proven by fine-needle sampling underwent primary chemotherapy followed by lumpectomy or mastectomy, level I and II axillary lymph node dissection, and irradiation. We studied pathologic complete responses (pCRs) of axillary nodes and breast tumors, as well as predictors of distant metastases. RESULTS: Thirty-five patients (23%) had axillary pCRs, and 20 patients (13.2%) had pCRs of primary breast tumors. Scarff-Bloom-Richardson grade 3 tumors (P = .04) and a clinical response to chemotherapy ≥ 50% (P = .003) were associated with negative axillary status at dissection. An initial tumor size ≤ 3 cm (63 patients) was associated with pCR of the primary tumor (P = .02) but not with complete histologic clearance of axillary lymph nodes. The median length of follow-up was 75 months. In the univariate analysis, age greater than 40 years (P = .003), absence of residual nodal disease (P = .01), and pCR of the tumor (P = .05) were associated with better distant disease-free survival. Five-year distant disease-free survival rates were 73.5% ± 14.9% among patients with no involved nodes at the time of surgery and 48.7% ± 9.2% among patients with residual nodal disease. In the multivariate Cox regression analysis, parameters associated with poor distant disease-free survival were age ≤ 40 years (P = .002), persistence of nodal involvement (P = .03), and S-phase fraction greater than 4% (P = .02). CONCLUSION: Our results suggest that axillary status is a better prognostic factor than response of the primary tumor to primary chemotherapy.

Background This retrospective study investigated the therapeutic benefit of adjuvant endocrine therapy (ET) in breast cancer patients with hormone receptor (HR) status change from positive to negative after neoadjuvant chemotherapy (NAC). Methods From December 2000 to November 2010, 97 eligible patients with a positive-to-negative switch of HR status after NAC were identified. All patients were categorized into 2 groups on the basis of the administration of ET: 57 ET-administered patients and 40 ET-naïve patients. Survival analyses were performed to examine the prognostic value of ET administration as well as other clinical and pathologic variables. Results The administration of ET was significantly associated with improved disease-free survival (p=0.018) in patients with a positive-to-negative switch of HR status. The 5-year disease-free survival rates were 77.0% and 55.5%, respectively, in ET-administered patients and ET-naïve patients. The 5-year overall survival rate for ET-administered patients was also higher than that of ET-naïve patients (81.3% vs. 72.7%, p=0.053), albeit this was statistically insignificant. Conclusions This study revealed that patients with HR altered from positive to negative after NAC still benefit from ET. The HR status should be evaluated not only in specimens obtained during post-NAC surgery but also in specimens biopsied before NAC.
