INTRODUCTIONBreast cancer (BC) is a major health problem in both developed and developing countries. Around the World, nearly 1.7 million new breast cancer cases were diagnosed in 2012 and this figure represented about 12% of all new cancer cases and 25% of all cancers in women. Since 2008, worldwide breast cancer incidence has increased by more than 20% and mortality has increased by 14 %. ABSTRACTBackground: Breast cancer is the most frequently diagnosed cancer among women in 140 of 184 countries worldwide. The association between breast cancer survival and socio-demographic and pathologic factors has been widely studied in the developed countries. But scarce data is available from Saudi Arabia. We aimed to determine the overall observed one year and three years survival rate of female breast cancer patients and to investigate the factors affecting survival rate. Methods: Retrospective data was collected from the cancer center registry at King Fahad Medical City (KFMC) that included all women diagnosed with breast cancer between 1 st January 2011 till 31 st December 2012 and were followed to 31 st December 2015 (cut off point for follow-up). Kaplan-Meier analysis was done to assess overall survival. The factors affecting survival rate such as age, histological type, tumor grade at diagnosis, metastases and treatment options were investigated using log rank test and Cox regression analysis. Results: The overall observed survival probability of the study population at 1, and 3 years was 95%, and 85%, respectively. The 3 year survivals for the younger (≤40 years), 41-50 years and older (50+ years) patients were 83.9%, 90.6% and 80.6% respectively, the differences not reaching statistical significance. There were statistically significant associations between three year survival and histological type of tumour, laterality, metastases and type of treatment by the univariate analysis log rank test. Conclusions: One and three-year survival rate of breast cancer at KFMC was 96% and 85% respectively. Investigating the factors affecting survival rate is one of the most essential means of improving cancer prognosis.

“…From here, a simple random sampling was used to select 2,000 cases of black non-Hispanic females and 91 cases of black Hispanic females for a total study sample of 2091 women diagnosed with cervical cancer. For more information of selection of patients by making use of random sampling, readers are referred to Khan et al 2014bKhan et al , 2014cKhan et al , 2014d. In addition, we used subject's demographic information (age at diagnosis and marital status) as well as cervical cancer information (tumor primary site, grading, behavior, and lymph node involvement) from the SEER dataset for statistical analysis.…”

Background: Globally, cervical cancer is a major public health concern. Cervical cancer is the second most common cancer among women, resulting in approximately 500,000 cases per year. The purpose of this study is to compare disease characteristics between Black Hispanic (BH) and Black non-Hispanic (BNH) women in the US. Materials and Methods: We used stratified random sampling to select cervical cancer patient records from the SEER database (1973-2009). We used Chi-square and independent samples t-test to examine differences in proportions and means. Results: The sample included 2,000 cervical cancer cases of Black non-Hispanic and 91 Black Hispanic women. There were statistically significant differences between black Hispanic and black nonHispanics in mean age at diagnosis (p<0.001), mean survival time (p<0.001), marital status (p<0.001), primary site of cancer (p<0.001); lymph node involvement (p<0.001); grading and differentiation (p<0.0001); and tumor behavior (p<0.001). Black women were more likely to develop cervical cancer and to have the highest mortality rates from the disease. Conclusions: Findings from this study show clear racial and ethnic disparities in cervical cancer incidence and prognosis that should be addressed.
