“…In the United Kingdom and Switzerland, BC mortality decreased about 30% between 1990 and 2006 (Bulliard et al, 2006), whereas in most Southern, Northern, and Western European countries the decline was between 15% and 25%, and in the Eastern Europe, breast cancer mortality only decreased moderately or remained stable during the same period (Hery et al, 2009;Autier et al, 2011). In contrast, Russia was experiencing an increase trend (Hirte et al, 2007), where the ASR increased until 2004 and decreased thereafter.…”

Background: Breast cancer is the most commonly diagnosed cancer in women worldwide In Iran, it ranks first among cancers diagnosed in women and is the fifth most common cause of death. The aim of this study was to present the mortality trends from breast cancer for Iranian women during a period of almost a decade, in order to provide update information regarding the likely future. Methods: We analyzed National death Statistic reported by the Iranian Ministry of Health and Medical Education from 1995 to 2004 to generate annual mortality rates/100,000, overall, by age group (<15, 15-49 and ≥50 years of age) and age standardized rate (ASR). Results: The age standardized mortality rate of breast cancer increased dramatically during these years from 1.40 to 3.52 per 100,000 and its mortality was increasing 151.4% for Iranian women, although it seemed that the rate leveled off from 2002 to 2004. Moreover the increasing rate was higher for those aged between 15-49 compared to age >50 years old. Conclusion: There is an increasing trend for breast cancer mortality in Iran. Thus, health education programs to rectify the lack of women awareness about breast cancer signs and effective screening are urgently needed.

“…The survival probability for breast cancer patients steadily increased over the period 1970-2000 in North, Central and South Europe [29], whereas in Russia and in Ukraine, there was an increase from 1960 to 2002 [30]. Because of fundamental difference in time periods, patient populations and treatment strategies, it does not make sense to compare results from the Charité to results from other clinics in German speaking countries [3,4,5].…”

Background: We have analyzed the patient population of one clinic (Charité) over a period of 15 years. Besides the changes in the technical facilities and therapeutical guidelines during these years, this period also reflects the changes in the health system attributable to the reunification of East and West Germany. Until now only few analyses for breast cancer patients from the German speaking area have been reported. Patients and Methods: All 2,062 patients undergoing surgical treatment for breast cancer between 1984 and 1998 were documented and followed up until 2007. The analysis included 1,560 patients with a primary breast cancer who fulfilled certain inclusion criteria. The treatment strategies applied to this population are presented in 3 time periods (1984-1990, 1991-1993, and 1994-1998). The effects of prognostic factors on overall survival were investigated using univariate analyses. Results: The percentage of pT1 tumors changed from 50.7% in the first period to 63.1% in the third period. The percentage of node-negative patients hardly changed with time (on average 61.6%). However, the percentage of patients with less than 10 assessed nodes decreased from 48.4% to 6.7% and 2.5% for the 3 periods, respectively. Therapeutic strategies changed drastically. Survival rate increased substantially, most likely due to improved therapeutic strategies, but also for other reasons not considered in the analysis.

“…(Finkelstein et al, 2003) Many studies have compared the trend of breast cancer mortality at different time intervals. (Zahl and Maehlen, 2005;Erbas et al, 2007;Hirte et al, 2007;Jatoi et al, 2007;Cabanes et al, 2009)In spite of large sample size and long follow up duration of most studies (Tabar et al, 1992), the transition probability of mortality in a cohort of breast cancer patients during long period was not accessible.…”

Introduction: Breast cancer is the most common cancer in women. Improvements of early diagnosis modalities have led to longer survival rates. This study aimed to determine the 5, 10 and 15 year mortality rates of breast cancer patients compared to the normal female population. Materials and Methods: The follow up data of a cohort of 615 breast cancer patients referred to Iranian Breast Cancer Research Center (BCRC) from 1986 to 1996 was considered as reference breast cancer dataset. The dataset was divided into 5 year age groups and the 5, 10 and 15 year probability of death for each group was estimated. The annual mortality rate of Iranian women was obtained from the Death Registry system. Standardized mortality ratios (SMRs) of breast cancer patients were calculated using the ratio of the mortality rate in breast cancer patients over the general female population. Results: The mean age of breast cancer patients at diagnosis time was 45.9 (±10.5) years ranging from 24-74. A total of 73, 32 and 2 deaths were recorded at 5, 10 and 15 years, respectively, after diagnosis. The SMRs for breast cancer patients at 5, 10 and 15 year intervals after diagnosis were 6.74 (95% CI, 5.5-8.2), 6.55 (95%CI, 5-8.1) and 1.26 (95%CI, 0.65-2.9), respectively. Conclusion: Results showed that the observed mortality rate of breast cancer patients after 15 years from diagnosis was very similar to expected rates in general female population. This finding would be useful for clinicians and health policy makers to adopt a beneficial strategy to improve breast cancer survival. Further follow-up time with larger sample size and a pooled analysis of survival rates of different centres may shed more light on mortality patterns of breast cancer.
