AbstractIntroductionBreast cancer is a foremost cause of death worldwide, ranks fifth among causes of death from all types of cancers; this is the most common cause of cancer death in women among both developing and developed countries. Breast cancer ranks first among most frequent cancers in women of Ethiopia. In spite of the high incidence, mortality rate, and survival status among breast cancer patients was not determined in Ethiopia.ObjectiveThe main aim of the study is to assess the survival status and predictor the mortality among Breast Cancer patients in Adult Oncology Unit at Black Lion Specialized Hospital in 2018.MethodsAn institution based retrospective follow up study was conducted in Adult Oncology Unit at Black Lion Specialized Hospital. All cases of breast cancer registered from 1st January 2012 to 31th December,2014 were followed for the six-year survival (until 31th December, 2017). Kaplan-Meier survival curve together with log rank test was deployed to test for variations in the survival among predictor variables. Cox regression was used at 5% level of significance to determine the net effect of each independent variable on time to death of breast cancer clients.ResultsThe results indicate that the incidence rate of mortality was 9.8 per 100 person/ years (95% CI: 8.49-11.47).The overall median survival time was 56.5(95% CI (53.46 - 60.83)) months. The overall estimated survival rate was recorded 27% (95% CI, 17.09 to 36.67 %) at 72 months of follow up, whereas at odd years (1, 3, and 5 years) were, 97.2%, 80.8%, and 46.2% respectively. Predictors of mortality were assessed at clinical stage (III&IV),(AHR =1.86), poorly differentiated histology (AHR: 3.1) & positive lymph node status (AHR:3.13),Whereas adjuvant hormone therapy (AHR: 0.67) and chemotherapy (AHR:0.72) were protective.ConclusionThe overall probability of survival in Ethiopia was inferior when compared with other high and middle-income countries. Predictors of mortality were at advanced clinical stage, poorly differentiated histology grade, surgical margin involvement and positive lymph node status. In contrary, adjuvant hormone therapy, modified radical mastectomy and chemotherapy were protective factors. Hence, special emphasis could be given to early screening, stage diagnosis and initiation of treatment.

PurposeThe basic helix-loop-helix transcription factor (bHLH) transcription factor Twist1 plays a key role in embryonic development and tumorigenesis. p53 is a frequently mutated tumor suppressor in cancer. Both proteins play a key and significant role in breast cancer tumorigenesis. However, the regulatory mechanism and clinical significance of their co-expression in this disease remain unclear. The purpose of this study was to analyze the expression patterns of p53 and Twist1 and determine their association with patient prognosis in breast cancer. We also investigated whether their co-expression could be a potential marker for predicting patient prognosis in this disease.MethodsTwist1 and mutant p53 expression in 408 breast cancer patient samples were evaluated by immunohistochemistry. Kaplan-Meier Plotter was used to analyze the correlation between co-expression of Twist1 and wild-type or mutant p53 and prognosis for recurrence-free survival (RFS) and overall survival (OS). Univariate analysis, multivariate analysis, and nomograms were used to explore the independent prognostic factors in disease-free survival (DFS) and OS in this cohort.ResultsOf the 408 patients enrolled, 237 (58%) had high mutant p53 expression. Two-hundred twenty patients (53.9%) stained positive for Twist1, and 188 cases were Twist1-negative. Furthermore, patients that co-expressed Twist1 and mutant p53 (T+P+) had significantly advanced-stage breast cancer [stage III, 61/89 T+P+ (68.5%) vs. 28/89 T-P- (31.5%); stage II, 63/104 T+P+ (60.6%)vs. 41/104 T-P- (39.4%)]. Co-expression was negatively related to early clinical stage (i.e., stages 0 and I; P = 0.039). T+P+ breast cancer patients also had worse DFS (95% CI = 1.217–7.499, P = 0.017) and OS (95% CI = 1.009–9.272, P = 0.048). Elevated Twist1 and mutant p53 expression predicted shorter RFS in basal-like patients. Univariate and multivariate analysis identified three variables (i.e., lymph node involvement, larger tumor, and T+P+) as independent prognostic factors for DFS. Lymph node involvement and T+P+ were also independent factors for OS in this cohort. The total risk scores and nomograms were reliable for predicting DFS and OS in breast cancer patients.ConclusionsOur results revealed that co-expression of mutant p53 and Twist1 was associated with advanced clinical stage, triple negative breast cancer (TNBC) subtype, distant metastasis, and shorter DFS and OS in breast cancer patients. Furthermore, lymph nodes status and co-expression of Twist1 and mutant p53 were classified as independent factors for DFS and OS in this cohort. Co-evaluation of mutant p53 and Twist1 might be an appropriate tool for predicting breast cancer patient outcome.

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.

Abstract Background:Axillary ultrasound (AUS) is one of the important bases for evaluating the axillary status of breast cancer patients. And it would be helpful for the reassessment of axillary lymph node status in these patients after neoadjuvant chemotherapy(NAC) and guide the selection of their axillary surgical options.The purpose of this study was to evaluate the diagnostic performance of ultrasound,and to find out the factors related to the outcome of ultrasound.Methods:In this retrospective analysis, 172 patients (one bilateral breast cancer) with breast cancer and clinical positive axillary nodes, were enrolled. After NAC, all patients received mastectomy and axillary lymph node dissection (ALND). AUS was used before and after NAC to assess the axilla status. Results:Of the 173 axillae, 137 (79.19%) had pathological metastasis after NAC. The accuracy, sensitivity, specificity, positive predictive value and negative predictive value of axillary ultrasound in this cohort were 68.21%, 69.34%, 63.89%, 87.96% and 35.38% respectively. Univariate analysis showed that primary axillary lymph node(ALN) short axis, progesterone receptors, hormone receptors, the tumor status after NAC, tumor reduction rate, ALN short axis after NAC, physical examination of axilla after NAC and pN impacted the results of AUS(P = 0.000 ~ 0.040). Multivariate analysis of the above indicators showed that ALN short axis after NAC and pN associated with AUS results independently. Conclusion:AUS can accurately assess axilla status after NAC in most breast cancer patients. If the short axis of ALN≥10mm and AUS negative, SLNB could be chosen. However, AUS cannot detect residual lymph node disease after NAC in a short axis of the ALN <10mm.
