OBJECTIVETo describe the current status of mortality breast cancer in Chinese females between 2004 and 2005, as well as its developing trend from 1973 to 2005.

METHODSThe data of female breast cancer deaths and number of female under exposure were collected through the Third National Mortality Retrospective Sampling Survey, which covered a total of 69 690 241 person years of females. The data was descriptively analyzed, and compared with the data of time-trend of breast cancer mortality in the previous two surveys in 1973 - 1975 and 1990 - 1992 respectively.

RESULTSThe crude mortality of female breast cancer in China in 2004 - 2005 was 5.90 per 100 000 (4112/69 690 241), ranking the sixth most common cancer death in Chinese females, and accounted for 5.90% (4112/69 667) of all female deaths from cancer. The crude mortality of female breast cancer was 6.86/100 000 (1777/25 900 856) in the eastern China, 5.91/100 000 (1431/24 225 738) in the central China and 4.62/100 000 (904/19 563 647) in the western China. The age-standardized mortality among Chinese standard population of female breast cancer in urban area (4.91/100 000, 1899 death cases) was 1.44 times higher than that in rural area (3.42/100 000, 2213 death cases). The crude mortality increased 99.99% from 1973 - 1975 (2.95/100 000) to 2004 - 2005 (5.90/100 000), the absolute figure increased by 2.95/100 000. The age-standardized mortality among Chinese standard population increased 37.85% from 1973 - 2005 (2.88/100 000) to 2004 - 2005 (3.97/100 000), the absolute figure increased 1.09/100 000.

CONCLUSIONThe mortality of female breast cancer in urban area was higher than that in rural area, and it decreased from the eastern China, to the central China and to the western China in turn. The mortality of female breast cancer has constantly increased in China since 1973.

The purpose of the present review is to give an overview of the association between alcohol intake and the risk of developing cancer. Two large-scale expert reports; the World Cancer Research Fund (WCRF)/American Institute of Cancer Research (AICR) report from 2007, including its continuous update project, and the International Agency for Research of Cancer (IARC) monograph from 2012 have extensively reviewed this association in the last decade. We summarize and compare their findings, as well as relate these to the public health impact, with a particular focus on region-specific drinking patterns and disease tendencies. Our findings show that alcohol intake is strongly linked to the risk of developing cancers of the oral cavity, pharynx, larynx, oesophagus, colorectum (in men), and female breast. The two expert reports diverge on the evidence for an association with liver cancer and colorectal cancer in women, which the IARC grades as convincing, but the WCRF/AICR as probable. Despite these discrepancies, there does, however, not seem to be any doubt, that the Population Attributable Fraction of alcohol in relation to cancer is large. As alcohol intake varies largely worldwide, so does, however, also the Population Attributable Fractions, ranging from 10% in Europe to almost 0% in countries where alcohol use is banned. Given the World Health Organization's prediction, that alcohol intake is increasing, especially in low- and middle-income countries, and steadily high in high-income countries, the need for preventive efforts to curb the number of alcohol-related cancers seems growing, as well as the need for taking a region- and gender-specific approach in both future campaigns as well as future research. The review acknowledges the potential beneficial effects of small doses of alcohol in relation to ischaemic heart disease, but a discussion of this lies without the scope of the present study.

OBJECTIVETo analyze the mortality trends and disease burden of malignant tumors in rural area of Feicheng city from 2000 to 2010, and to provide basic information for the prevention and treatment of malignant tumors in this area.

METHODSThe data of cancer mortality from 2000 to 2010 from Feicheng Cancer Registry database were checked. Mortality rate, standardized mortality rate, potential years of life Iost (PYLL), standardized potential years of life lost (SPYLL), average years of life lost (AYLL) and other indexes were calculated and analyzed. The trend of the standardized rates transformed by the natural logarithm over time was assessed by Prais-Winsten regression method in which the errors was assumed to follow a first-order autoregressive process. STATA 12.0 was used to analyze the data.

RESULTSIn average, the crude mortality rate was 199.67 per 100 000 (264.69 per 100 000 in males and 137.24 per 100 000 in females), and the standardized mortality rate was 157.00 per 100 000 (200.49 per 100 000 in males and 101.31 per 100 000 in females). There were no significant changes in the trends of all standardized rates. For males, the mortality rates of lung and colorectal cancers increased significantly, and for females, the rates of lung and breast cancers had increased trend while the rate of esophageal cancer showed a downward trend. There were no statistically significant changes in other main malignant tumors. During 2000 to 2010, the PYLL of malignant tumors in Feicheng was 183 685.0 person-years, and PYLL rate was 23.3 per 1000. The SPYLL was 153 091.0 person-years, SPYLL rate was 19.4 per 1000, and AYLL was 14.8 years.

CONCLUSIONSThere are no obvious changes in the trends of standardized mortality rates in rural area of Feicheng over the past 11 years. For males, the mortality of lung cancer and colorectal cancer is increasing, and for females, the rates of lung and breast cancers have an increasing trend while the rate of esophageal cancer shows a decreasing trend. The prevention and control of digestive malignant tumors, lung cancer and breast cancer are getting seriously important and should be the focal point in this issue.

In 2002, breast became the most common cancer site in Korean women. Using national breast cancer incidence data during 1993-2002, crude, age-standardized, and age-specific rates for incidence and mortality were calculated. Survival was examined for cases diagnosed during 1993-2002 and followed up to 2004. Observed survival was calculated using the life table method and relative survival using the Ederer II method. Age-standardized incidence rates in female increased from 14.5 in 1993 to 26.2 per 100,000 in 2002. Age-specific incidences showed peaks in women in their forties. Mortality rates increased from 3.7 in 1993 to 4.6 per 100,000 in 2002 and showed peaks in women in their fifties. Five-year relative survival for female breast cancer diagnosed during 1993-2002 was 82.2%. When we examined the secular trends using cases diagnosed 1993-1999 for complete 5-yr follow-up, the 5-yr relative survival increased from 75.2% in 1993 to 83.5% in 1999. The data from this study will provide valuable information to plan and evaluate actions against breast cancer including national breast cancer screening.

OBJECTIVETo understand the disease burden caused by cancers in Jinchang cohort, and develop effective strategies for cancer prevention and control in this population.

METHODSThe cancer mortality data from 2001 to 2013 and the medical records for cancer patients from 2001 to 2010 in Jinchang cohort were collected. The disease burden caused by cancer was analyzed by using mortality rate, potential years of life lost (PYLL), working PYLL (WPYLL), and direct economic burden.

RESULTSDuring 2001-2013, in Jinchang cohort, the five leading cancers ranked by mortality rate were lung cancer (78.06/100,000), gastric cancer (38.03/100,000), liver cancer (37.23/100,000), esophageal cancer (19.06/100,000), and colorectal cancer (9.53/100,000). The five leading cancers in terms of PYLL (person-years) and WPYLL (person-years) were lung cancer (3480.33, 1161.00), liver cancer (2809.03, 1475.00), gastric cancer (2120.54, 844.00), esophageal cancer (949.61, 315.00), and colorectal cancer (539.90, 246.00). From 2001 to 2010, the five leading cancers in term of average daily cost of hospitalization were gastric cancer (8,102.23 Yuan), esophageal cancer (7135.79 Yuan), colorectal cancer (7064.38 Yuan), breast cancer (6723.53 Yuan), and lung cancer (6309.39 Yuan).

CONCLUSIONSThe cancers common causing higher disease burden in Jinchang cohort were lung cancer, gastric cancer, liver cancer, esophageal cancer and colorectal cancer. The lung cancer disease burden was the highest.

PURPOSE: The purpose of this study is to evaluate the role of regular postoperative surveillance to improve the prognosis of patients with breast cancer after curative surgery. MATERIALS AND METHODS: We retrospectively analyzed the medical records of 4,119 patients who received curative surgery for breast cancer at Samsung Medical Center between January 2000 and September 2008. Patients were divided into two groups (group I, regular postoperative surveillance; group II, control group) according to their post-therapy follow-up status for the first 5 years after surgery. RESULTS: Among the 3,770 patients selected for inclusion, groups I and II contained 3,300 (87%) and 470 (13%) patients, respectively. The recurrence rates at 5 years for groups I and II were 10.6% and 16.4%, respectively (hazard ratio, 0.85; 95% confidence interval [CI], 0.67 to 1.09; p=0.197). The 10-year mortality cumulative rates were 8.8% for group I and 25.4% for group II (hazard ratio, 0.28; 95% CI, 0.22 to 0.35; p < 0.001). In multivariate analysis for recurrence-free survival (RFS), age over 40 years (p < 0.001), histologic grade 1 (p < 0.001), and pathologic stage I (p < 0.001) were associated with longer RFS but not with follow-up status. Multivariate analysis for overall survival (OS) revealed that patients in group I showed significantly improved OS (hazard ratio, 0.29; 95% CI, 0.23 to 0.37; p < 0.001). Additionally, age over 40 years, histologic grade I, and pathologic stage I were independent prognostic factors for OS. CONCLUSION: Regular follow-up for patients with breast cancer after primary surgery resulted in clinically significant improvements in patient OS.

Breast cancer (BC) is the main common cause of cancer mortality among women in the world. This study aims at investigating BC epidemiology and identifying the different risk factors associated and the most affecting ones among women in the Gaza Strip, Palestine. This study was a hospital-based case-control (1:2), as the study was carried out over the period of October 2014 to February 2015. A total of 105 BC patients, chosen from Al-Shifa Hospital in Gaza City and European hospital for the south governorate, were the case and compared to 209 women as a control group who matched the cases in age, residence, and with no history of breast problems. The age of the enrolled cases and controlled ranged between 18 to 60 years. The face-to-face interview was conducted during the patient visit to the oncology department and the control visit in their home. The result illustrated that women who had late pregnancy (> 35 years) (odds ratio [OR], 11.56; 95% confidence interval [CI], 1.64–81.35), or high body mass index (BMI; ≥ 30 kg/m²) (OR, 4.70; 95% CI, 1.62–13.69), or first-degree family history of BC (OR, 2.7; 95% CI, 1.04–7.20), or hypertensive patients (OR, 12.13; 95% CI, 1.93–76.10), or diabetic (OR, 6.84; 95% CI, 1.77–26.36) were more likely to have increased BC risk. The findings of the present study suggest that positive family history of BC, high BMI, and some common diseases (hypertension, diabetes mellitus) may be the epigenetic factors promoting the occurrence of BC.

OBJECTIVETo analyze the incidence and mortality trends of female breast cancer in urban and rural areas of Beijing from 2004 to 2008.

METHODSThe incidence and mortality data of female breast cancer from 2004 to 2008 were sorted from Beijing Cancer Registry Database, including 15 527 new diagnosed cases and 3219 deceased cases in total, covering population 29 351 258 person years; among which 11 065 new cases and 2378 deceased cases were from urban areas, covering 17 877 128 person years and 4462 new diagnosed cases and 841 deceased cases were from rural areas, covering 11 474 130 person years. The incidence cases aged 25 and above were divided into 13 age groups by 5 years. The cases under 49 years (≤ 49) and over 49 years (> 49) were separately defined as premenopausal group and postmenopausal group. Incidence and mortality rates in each year, age-specific incidence and mortality rates in urban and rural areas in Beijing were calculated. The annual standard incidence and mortality rates were adjusted by world population constitution; and the incidence rates ratio in different years related to the place of residence, urban or rural were calculated. JoinPoint software was applied to analyze the incidence trend and calculated the annual percentage of changing (APC).

RESULTSThe age of female breast cancer patients in urban Beijing in 2004 was (55.83 ± 13.01), while it changed to (56.10 ± 12.80) in 2008, increasing by 0.27 years old. The proportion of the patients who were under 49 years declined from 38.32% (732/1910) in 2004 to 34.02% (894/2628) in 2008. While the average age of the patients in rural areas have improved 0.21 year old, from (52.15 ± 11.33) years old in 2004 to (52.36 ± 11.59) years old in 2008; and the proportion of the patients under 49 years also declined from 45.44% (314/691) in 2004 to 43.40% (454/1046) in 2008. From 2004 to 2008, the incidence and mortality rate of female breast cancer in urban areas of Beijing separately rose from 55.43/100 000 (1910/3 445 812) and 10.65/100 000 (367/3 445 812) to 70.70/100 000 (2628/3 717 436) and 15.01/100 000 (558/3 717 436). And in rural areas, those rates separately rose from 30.60/100 000 (691/2 257 953) and 5.54/100 000 (125/2 257 953) in 2004 to 44.78/100 000 (1046/2 336 040) and 7.49/100 000 (175/2 336 040) in 2008. After adjusting by world population constitution, the difference showed no statistical significance in mortality trend of female breast cancer in rural areas of Beijing (P > 0.05). In year 2004, the female breast cancer incidence rate ratio of urban to rural areas in Beijing fluctuated between 1.34 and 4.47, with the average ratio value at 1.81. In year 2008, the ratio value fluctuated between 1.15 and 2.37, with the average ratio value at 1.57. During 2004 and 2008, the peak age group of the female breast cancer incidence in urban areas was in 60 - 64 years old group, with the rate of 126.92/100 000 (998/786 300) whereas the mortality rate was increasing within aging. In rural areas the peak age groups of the incidence and mortality were separately in 50 - 54 and 80 - 84 years old groups, with the rate of 80.63/100 000 (793/983 516) and 29.17/100 000 (40/137 132) respectively.

CONCLUSIONThe incidence and mortality of breast cancer in urban areas in Beijing, as well as the incidence of breast cancer in rural areas in Beijing showed increasing trend annually. The gap in breast cancer incidence between rural and urban areas in Beijing was narrowing, while the incidence rate among different aging groups and the peak mortality rate showed significant difference between urban and rural areas in Beijing.

OBJECTIVETo observe the trend in the change of incidence and mortality of female breast cancer in Tianjin and evaluate its effect of prevention.

METHODSMethod of descriptive epidemiology was used to study the epidemic situation of female breast cancer in Tianjin.

RESULTSThe incidence of breast cancer in Tianjin had increased by 39.7% from 1981 to 1997, as compared with the other cities in China. Especially, compared with the developed countries the world over, the incidence of breast cancer in Tianjin is much lower. The mortality rate of breast cancer had lowered by 31.0% from 1981 to 1997 and the 3-year and 5-year survival rates increased to various degrees.

CONCLUSIONEarly detection and diagnosis of breast cancer are very important to both increase of survival and lowering of mortality of breast cancer. Preventive efforts should be made to the high risk people of breast cancer.

PURPOSE: To investigate clinicopathological characteristics and outcomes of male breast cancer (MBC). PATIENTS AND METHODS: We retrospectively analyzed the data of 20 MBC patients in comparison with female ductal carcinoma treated at Yonsei University Severance Hospital from July 1985 to May 2007. Clinicopathological features, treatment patterns, and survival were investigated. RESULTS: MBC consists of 0.38% of all breast cancers. The median age was 56 years. The median symptom duration was 10 months. The median tumor size was 1.7cm, 27.8% showed node metastasis, and 71.4% were estrogen receptor positive. All 20 cancers were arisen from ductal cells. No lobular carcinoma was found. The incidence of stages 0, I, II, and III in patients were 2, 10, 4, and 3, respectively. All patients underwent mastectomy. One with invasive cancer did not receive axillary node dissection and stage was not exactly evaluated. Adjuvant treatments were determined by pathologic parameters and stage. Clinicopathological parameters and survival rates of MBC were comparable to those of female ductal carcinoma. CONCLUSION: The onset age of MBC was 10 years older and symptom duration was longer than in female patients. No difference in outcomes between MBC and female ductal carcinoma suggests that the biology of MBC is not different from that of females. Therefore, education, an appropriate system for early detection, and adequate treatment are necessary for improving outcomes.
