217 Background: Reproductive age breast cancer patients often experience therapy-related amenorrhea so preserving fertility after treatment is a major concern. Anti-mullerian hormone (AMH) values have been reported useful in predicting menopause for infertility treatment patients, but published information is limited regarding breast cancer patients. If amenorrhea can be predicted before treatment, breast cancer patients hoping to have children in the future can consider this information in choosing treatment. Our aim was to predict patient fertility using AMH values. Methods: Forty breast cancer patients, 25-45 years of age (median, 35.5), who received adjuvant chemotherapy (CT) or endocrine therapy (ET), had AMH values retrospectively assayed from frozen serum before and after treatment. AMH values were then analyzed in relation to clinicopathological factors using logistic analysis. Of 19 adjuvant CT patients whose AMH values could be assayed, Cox’s proportional hazard model indicated a correlation in terms of amenorrhea and time to menses resumption between clinicolpathological factors and AMH values. Results: The mean pretreatment AMH value for all 40 patients was 21.4pM (range, 3-78) and a correlation was demonstrated with patient age, but not breast cancer intrinsic subtype or stage. AMH values decreased to the lower limit after treatment for all CT patients regardless of age, but there was a difference in degree depending on patient age for ET patients. Of the 19 CT patients, the mean AMH value was 25.6pM (3-78). These patients all underwent a regimen of anthracycline with 11 (58%) also receiving a regimen of taxiane. After starting CT, 17 patients (89%) experienced amenorrhea, but 11 (59%) resumed menstruation within one year of finishing CT and 15 (78%) resumed within two years. There were no significant differences among CT patients in age, pretreatment AMH value, intrinsic subtype or stage, but patients receiving taxiane demonstrated a noteworthy trend. Conclusions: Although we were unable to predict menopause directly using AMH values given the small number of patients in this study, we could estimate the risk of menopause as being either low or high for CT patients based on age and type of regimen.

BACKGROUND: AGR2 expression is associated with luminal breast cancer. Overexpression of AGR2 is a predictor of poor prognosis. Several studies have found correlations between AGR2 in disseminated tumor cells (DTCs) in breast cancer patients. OBJECTIVE: This study aims to determine the correlation between anterior Gradient2 (AGR2) expression with the incidence of distant metastases in luminal breast cancer. METHODS: This study was an observational study using a cross-sectional method and was conducted at Wahidin Sudirohusodo Hospital and the network. ELISA methods examine AGR2 expression from blood serum of breast cancer patients. To compare the AGR2 expression in metastatic patients and the non-metastatic patient was tested with Mann Whitney test. The correlation of AGR2 expression and metastasis was tested with the Rank Spearman test. RESULTS: The mean value of AGR2 antibody expression on ELISA in this study was 2.90 ± 1.82 ng/dl, and its cut-off point was 2.1 ng/dl. Based on this cut-off point value, 14 subjects (66.7%) had overexpression of AGR2 serum ELISA, and 7 subjects (33.3%) had not. The mean value AGR2 was significantly higher in metastatic than not metastatic, 3.77 versus 1.76 (p < 0.01). The Spearman rank test obtained a p-value for the 2 tail test of 0.003 (p < 0.05), which showed a significant correlation of both, while the correlation coefficient of 0.612 showed a strong positive correlation of AGR2 overexpression and metastasis. CONCLUSIONS: AGR2 expression is correlated with metastasis in Luminal breast cancer.

This study aimed to explore efficient ways to diagnose bone metastasis early using bone scintigraphy images through negative mining, pre-training, the convolutional neural network, and deep learning. We studied 205 prostate cancer patients and 371 breast cancer patients and used bone scintigraphy data from breast cancer patients to pre-train a YOLO v4 with a false-positive reduction strategy. With the pre-trained model, transferred learning was applied to prostate cancer patients to build a model to detect and identify metastasis locations using bone scintigraphy. Ten-fold cross validation was conducted. The mean sensitivity and precision rates for bone metastasis location detection and classification (lesion-based) in the chests of prostate patients were 0.72 ± 0.04 and 0.90 ± 0.04, respectively. The mean sensitivity and specificity rates for bone metastasis classification (patient-based) in the chests of prostate patients were 0.94 ± 0.09 and 0.92 ± 0.09, respectively. The developed system has the potential to provide pre-diagnostic reports to aid in physicians’ final decisions.

e12587 Background: : Although post mastectomy Immediate breast reconstruction has shown to improve physical and psychosocial well-being of breast cancer patients, this is not a usual procedure in Pakistan due to limited resources and lack of awareness. The aim of our study is to evaluate patient’s satisfaction/ aesthetic outcomes between the patients undergoing mastectomy alone (Group A) and the ones undergoing mastectomy followed by immediate reconstruction (Group B). Methods: This is a prospective study conducted at Shaukat Khanum Hospital Pakistan comparing aesthetic outcome, patient’s satisfaction and Quality of life between two groups using Breast Q module. All patients undergoing mastectomy with and without reconstruction between April 2017 to July 2019 are included. Sample size of 84 was calculated (42 in each group). Results: The mean Q score of satisfaction with the breast in group B is 82.64 and in group A is 35.82 (P = 0.001). The mean Q score of Psychosocial well-being in group B is 89 vs 44.95 in group A (P = 0.001). The mean Q score of Physical well-being in group B is 98.23 vs 90.41 in group A (P = 0.002). The mean Q score of sexual well-being in group B is 81.93 vs 43 in Group A (P = 0.001). [Mean difference in score of 5-10 - little change, 10-20 - moderate change, > 20 - significant change].The mean difference between two groups in satisfaction with breast , psychosocial well-being and sexual well-being is more than 20 with a statistically significant p-value, while in physical well-being the mean difference is 7.8 which falls in little change group. Conclusions: Our study shows that reconstruction helps breast cancer patients in providing comprehensive care in a manner that they achieve a higher satisfaction with their appearance, psychological and sexual well-being without compromising oncological safety and this should be practiced more in our country. Also patients education about these procedures should be raised to help them fighting against this disease

Abstract Background: For several years, HER2-positive breast cancer was associated with poor outcomes and higher mortality rates than other breast cancer subtypes. Nevertheless, the advent of Trastuzumab has significantly changed the treatment paradigm of HER2-positive breast cancer. However, it is not an affordable treatment option in sub-Saharan African countries. Besides, there was a lack of comprehensive data about the survival outcomes of HER2-positive breast cancer patients in our setting. Hence, the present study aimed to determine the survival outcomes among HER2-positive breast cancer patients at the Oncology Department of Kenyatta National Hospital.Methods: A hospital-based retrospective cohort design was used to evaluate the survival outcomes, and associated factors among patients with HER2-positive breast cancer admitted between 2015 and 2019 at Kenyatta National Hospital. A total of 50 eligible HER2-positive breast cancer patients were included in the study. In the pre-designed data abstraction tool, the data were collected by reviewing the medical records of the patients. The data were entered and analyzed using the Statistical Package for the Social Sciences version 27 software. The mean survival time was estimated using Kaplan Meier survival analysis. Cox regression analysis was employed to estimate the predictors of mortality among HER2-positive breast cancer patients.Results: The study showed that the overall survival rate was 30%, with a significant decrease in the percentage survival rate across the five years. More than half of the study participants (26, 52%) showed cancer progression during the last follow-up period. The present study showed that the mean cancer-specific survival rate among the study patients was 26.74±18.395 months. The study showed that the mean survival time of patients aged below 60 years (32.513 months), without co-morbidities (34.40 months), and the early stage of the disease (50.639 months) was higher than their counterparts. Multivariate cox-regression analysis revealed that advanced stage (AHR=13.1, 95% CI=2.6-66.6, P=0.002 and distant metastasis (AHR=15.0, 95% CI=3.6-62.8, P≤0.001) were the significant predictors of mortality among HER2 positive breast cancer patients.Conclusions: The overall survival rate of HER 2 positive breast cancer was 30%. Advanced stage and distant metastasis were the significant predictors of mortality among HER2-positive breast cancer patients.
