Background Overall survival of breast cancer patients has been calculated many times but there is no precise research available regarding the survival time of breast cancer patients after recurrence. We investigated the effects factors on mortality due to breast cancer. Methods All Factors were analyzed using statistical tools and techniques to find out rate of mortality after recurrence. Descriptive statistics, cox proportional hazard models were used to find statistical significant variables. In the present study recurrence is considered as an important event which may play a role in study of breast cancer progression. In this study, we evaluated breast cancer risk factors in relation to mortality due to this disease among 1028 women with breast cancer in Lahore, Pakistan. Hazard ratios (HRs) and 95% confidence intervals (CIs) for the associations between risk factors and mortality due to breast cancer were estimated in subtype-specific Cox regression models. Results Survival of breast cancer patients depends upon many factors. A total of 581 alive and 447 deaths due to breast cancer occurred during a median follow-up period of 1977 days. Median survival time after recurrence was 3 years. Significant factors were included post- menopausal women who diagnosed and had recurrence at the age < 45 of molecular subtype estrogen receptor positive, progesterone receptor negative, Her2.neu positive with tumor size ≥ 3 & involved lymph nodes >5. Radiotherapy has increased life span of patients even after recurrence. Conclusion Younger women had higher risk of mortality after recurrence even gone through chemotherapy while lower grade tumor had good prognosis. Radiotherapy played a major role in increasing life time of breast cancer women after recurrence. Our findings are consistent with those from previously published data.

Abstract Background: Tumour subtype have a significant effect on bone metastasis in breast cancer, but population-based estimates of the prognosis of bone metastases at diagnosis of breast cancer are lacking. The aim of this study was to analyse the influence of tumour subtype and other factors in the prognostic and survival of patients with bone metastases of breast cancer. Methods: Using the Surveillance, Epidemiology, and End Results Program (SEER) data of 2012 to 2016 conducted a retrospective cohort study to investigate patients with bone metastases in breast cancer. Patients characteristic according subtypes were compared using chi-square, overall survival (OS), prognostic factor calculated using the Kaplan-Meier method and the Cox proportional hazards model. Results: A total of 3384 patients were included in this study. 63.42% were HR+/HER2-, 19.86% were HR+/HER2+, 9.34% were HR-/HER2-, and 7.39% were HR-/HER2+. Median OS for the whole population was 38 months, and 33.9% of the patients were alive at five-year. The median OS and five-year survival rate among the different molecular subtype of breast cancer patients are significant differences (p<0.05). Multivariate Cox regression analysis showed that age of 55-59 ( HR=1.270 ), black race ( HR=1.320 ), grade in III or IV ( HR=1.952 ), HR-/HER2- ( HR=2.727), lung metastases (HR=1.249), live metastases (HR=1.840), brain metastases (HR=1.812) only bone metastases ( HR=1.237) are independent risk factors of prognosis; married ( HR=0.812 ), HR+/HER2+ ( HR=0.618 ), HR-/HER2+ (HR=1.237), insurance ( HR=0.597 ) and surgery (HR=0.512) are independent protection factors of prognosis. Conclusions: There were substantial differences in OS according to tumour subtype. In addition to tumour subtype, other independent predictors of OS are age at diagnosis, race, marital status, insurance, grade, surgery and visceral metastases. Tumour subtype, as a significant prognostic factor, warrant further investigation. Keywords: Breast cancer, Bone metastases, Tumour subtype, Prognosis factor, Survival

Anthracycline-based regimens with or without anti-human epidermal growth factor receptor (HER) 2 agents such as trastuzumab are effective in breast cancer treatment. Nevertheless, heart failure (HF) has become a significant side effect of these regimens. This study aimed to investigate the incidence and factors associated with HF in breast cancer patients treated with anthracyclines with or without trastuzumab. A retrospective cohort study was performed in patients with breast cancer who were treated with anthracyclines with or without trastuzumab between 1 January 2014 and 31 December 2018. The primary outcome was the incidence of HF. The secondary outcome was the risk factors associated with HF by using the univariable and multivariable cox-proportional hazard model. A total of 475 breast cancer patients were enrolled with a median follow-up time of 2.88 years (interquartile range (IQR), 1.59–3.93). The incidence of HF was 3.2%, corresponding to an incidence rate of 11.1 per 1000 person-years. The increased risk of HF was seen in patients receiving a combination of anthracycline and trastuzumab therapy, patients treated with radiotherapy or palliative-intent chemotherapy, and baseline left ventricular ejection fraction <65%, respectively. There were no statistically significant differences in other risk factors for HF, such as age, cardiovascular comorbidities, and cumulative doxorubicin dose. In conclusion, the incidence of HF was consistently high in patients receiving combination anthracyclines trastuzumab regimens. A reduced baseline left ventricular ejection fraction, radiotherapy, and palliative-intent chemotherapy were associated with an increased risk of HF. Intensive cardiac monitoring in breast cancer patients with an increased risk of HF should be advised to prevent undesired cardiac outcomes.

Abstract Background Hand-foot syndrome (HFS) is a side effect of skin related to pegylated liposomal doxorubicin (PLD) application. Moderate to severe hand-foot syndrome (MSHFS) might have a serious impact on patients’ quality of life and treatment. However, information on risk factors for the development of MSHFS is still limited. To analyze the risk factors for PLD-induced MSHFS in breast cancer patients and constructed a logistic regression prediction model. Methods We conducted a retrospective analysis of breast cancer patients who were treated with a PLD regimen in the Tumor Hospital of Harbin Medical University from January 2017 to August 2019. A total of 26 factors were collected from electronic medical records. Patients were divided into MSHFS (HFS > grade 1) and NMHFS (HFS ≤ grade 1) groups according to the NCI classification. Statistical analysis of these factors and the construction of a logistic regression prediction model based on risk factors. Results A total of 44.7% (206/461) of patients developed MSHFS. The BMI, dose intensity, and baseline Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST) levels in the MSHFS group, as well as good peripheral blood circulation, excessive sweat excretion, history of gallstones, and tumour- and HER2-positive percentages, were all higher than those in the NMHFS group (P < 0.05). The model for predicting the occurrence of MSHFS was P = 1/1 + exp. (11.138–0.110*BMI-0.234*dose intensity-0.018*baseline ALT+ 0.025*baseline AST-1.225*gallstone history-0.681* peripheral blood circulation-1.073*sweat excretion-0.364*with or without tumor-0.680*HER-2). The accuracy of the model was 72.5%, AUC = 0.791, and Hosmer-Lemeshow fit test P = 0.114 > 0.05. Conclusions Nearly half of the patients developed MSHFS. The constructed prediction model may be valuable for predicting the occurrence of MSHFS in patients.

Abstract: Breast cancer is the most common cancer in woman. Metastasis often occurs especially to the bones. This study was aimed to determine the characteristics of breast cancer patients with bone metastasis. This was a descriptive study with a cross-sectional design. Samples were 46 breast cancer patients with bone metastasis recorded at Sanglah Hospital from 2014 until 2018. Data of pathological examination archives of Oncology Surgery Division Medical Faculty of Udayana University/Sanglah General Hospital were used to obtain the clinicopathological characteristics of metastatic breast cancer patients based on age, lateralization, histopathological type, and tumor molecular subtype. The results showed that most cases of metastatic breast cancer were aged 40-49 years as many 21 patients (45.7%), minimal difference in lateralization between right breast as many 22 patients (47.8%) and left breast 23 patients (50%). The most common histopathological type was invasive carcinoma of no special type as many 34 patients (73.9%). The most common tumor subtype was the luminal B subtype as many 21 patients (45.7%). In conclusion, most patients of breast cancer with bone metastasis were 40-49 years old, invasive carcinoma of no special type, molecular subtype of luminal B, and no significant difference between lateralization to the right and left breast.Keywords: breast cancer, bone, metastasis, clinicopathological caharacteristics Abstrak: Kanker payudara merupakan jenis kanker yang paling sering dijumpai pada wanita.

We mined published microarray data (1) to understand the most significant gene expression differences in the tumors of triple negative breast cancer patients based on survival following treatment: dead or alive. We observed significant transcriptome-wide differential expression of vacuolar protein sorting 52, encoded by VPS52 when comparing the primary tumors of triple negative breast cancer patients dead or alive. Importantly, VPS52 expression was correlated with recurrence-free survival in basal subtype breast cancer, a molecular subtype sharing significant overlap with triple negative breast cancer. VPS52 may be of relevance as a biomarker or as a molecule of interest in understanding the etiology or progression of triple negative breast cancer.
