Background: The present study aimed to investigate breast cancer trend, incidence, and mortality among Iranian women and was one of the first provincial and population-based studies to investigate breast cancer changes during 14 years in the largest province of Iran, Kerman. Methods: This was a population-based longitudinal study. Information about women diagnosed with breast cancer from 2001 to 2014 was obtained from the Cancer Registry of Kerman University of Medical Sciences. Independent-samples t test, one-way analysis of variance, linear regression, time series graphs, and fitted line plots were performed using SPSS 22 and Minitab 17.Results: A total of 2771 women were diagnosed with breast cancer in Kerman province from 2001 to 2014. The mean age of female patients was 49.52±12.88 years. The total incidence rate was 13.5 per 100,000 women and there was an increasing trend for incidence and age at diagnosis. Also, 254 women died from breast cancer during these 14 years and the mean mortality age was 54.16±14.33 years. There was also an increasing trend for mortality and age of death.Conclusion: There is an increasing trend for incidence and mortality from breast cancer in Kerman province and this requires interventions such as appropriate screening programs. Also, enabling physicians and increasing patient awareness to identify breast cancer symptoms is necessary.

Introduction. Breast cancer (BC) is one of the most common malignancies within female incidence and mortality patterns in the RF. Study objective. To analyze BC incidence in females exposed to occupational ionizing radiation over prolonged periods. Materials and methods. The study cohort included 5689 females who had been occupationally exposed to ionizing radiation throughout 1948-1982 and followed up until 31.12.2018. Results. BC was on the top of the list among females of the study cohort (11.9%). BC prevalence rate in the female cohort understudy was 28.3% as of 31.12.2018. The standardized BrCa incidence rate was 0.88 ± 0.07 per 1000 person-years of the follow-up. The absolute BrCa case increase in the females was 1.29, with the rise of 232.48% by the end of the follow-up due to the rise in age categories of females and the elevating risk of the disease occurrence. Discussion. The study cohort of females demonstrated standardized BrCa incidence rates consistent with the corresponding estimates for the general female population of the RF. Meanwhile, the observed rates were lower than those estimated for the female population of the Chelyabinsk region. The increasing trend of the standardized BC incidence rate by the end of the follow-up period (31.12.2018) was consistent with WHO statistics. The extended follow-up for an updated assessment of ionizing radiation effect on BC incidence is required to develop new cancer prevention strategies. Conclusion. The study demonstrated that BC incidence rates in the study cohort varied by age and calendar period of the follow-up. The increasing trend of the standardized rates of BC incidence was observed by the end of the follow-up.

PurposeTo investigate the 5-year changes in static and dynamic anterior segment optical coherence tomography (AS-OCT) parameters and their predictors.MethodsThis was a prospective, population-based cohort study of people aged 50 years and older residing in the Liwan District, Guangzhou, China. Standardised AS-OCT scans were performed in November 2008 and November 2013 under dark and light conditions. Customised software was used to analyse horizontal AS-OCT images. Parameters in dark and measurements of light-to-dark changes were used for analyses.ResultsA total of 186 (71.8%) subjects underwent AS-OCT twice, 5 years apart and were included for analyses. The mean age in 2008 was 64.7±7.0 years, and 60.2% were women. The anterior chamber width (ACW) decreased from 11.74±0.44 mm in 2008 to 11.60±0.37 mm in 2013 (p=0.001). There was a trend towards a decrease in dynamic capacity (light-to-dark changes) in the anterior segment, with decreased iris thickness at 750 µm (ΔIT750), ΔACW, Δ anterior chamber area (ACA) and Δ pupil diameter at 5 years (all p<0.05). After adjusting for age and sex, the following baseline parameters were associated with a greater decrease rate in trabecular iris space area at 500 µm (TISA500) at 5 years: TISA500, IT750 and ACA in dark (p<0.001 for all).ConclusionsAnterior chamber angle width decreased and the amount of light-to-dark changes declined during 5-year follow-up. Subjects with greater height, wider angle width and thicker iris at baseline have greater angle narrowing at follow-up.

ObjectiveWe examined the risk of primary gastrointestinal cancers in women with breast cancer and compared this risk with that of the general population.DesignUsing population-based Danish registries, we conducted a cohort study of women with incident non-metastatic breast cancer (1990–2017). We computed cumulative cancer incidences and standardised incidence ratios (SIRs).ResultsAmong 84 972 patients with breast cancer, we observed 2340 gastrointestinal cancers. After 20 years of follow-up, the cumulative incidence of gastrointestinal cancers was 4%, driven mainly by colon cancers. Only risk of stomach cancer was continually increased beyond 1 year following breast cancer. The SIR for colon cancer was neutral during 2–5 years of follow-up and approximately 1.2-fold increased thereafter. For cancer of the oesophagus, the SIR was increased only during 6–10 years. There was a weak association with pancreas cancer beyond 10 years. Between 1990–2006 and 2007–2017, the 1–10 years SIR estimate decreased and reached unity for upper gastrointestinal cancers (oesophagus, stomach, and small intestine). For lower gastrointestinal cancers (colon, rectum, and anal canal), the SIR estimate was increased only after 2007. No temporal effects were observed for the remaining gastrointestinal cancers. Treatment effects were negligible.ConclusionBreast cancer survivors were at increased risk of oesophagus and stomach cancer, but only before 2007. The risk of colon cancer was increased, but only after 2007.

PURPOSE: In this multicenter trial, toremifene 40 mg/d was compared with tamoxifen 20 mg/d, both given orally for 3 years to postmenopausal, axillary node–positive women after breast surgery. PATIENTS AND METHODS: The first 899 patients (toremifene, n = 459; tamoxifen, n = 440) of the total of 1,480 patients accrued to the trial were included in this scheduled safety analysis. The mean follow-up time was 3.4 years. RESULTS: The two treatment groups were well balanced with respect to patient and disease characteristics. The subjective side-effect profile was similar in both treatment groups. Slightly more vascular complications (deep vein thromboses, cerebrovascular events, and pulmonary embolisms) were seen among tamoxifen-treated patients (5.9%) as compared with toremifene-treated patients (3.5%) (P = .11), whereas bone fractures (P = .09) and vaginal leukorrhea (P = .05) were more common in the toremifene group. The number of subsequent second cancers was similar. The breast cancer recurrence rate was 23.1% (n = 106) in the toremifene group and 26.1% (n = 115) in the tamoxifen group (P = .31). When only patients with estrogen receptor (ER)–positive cancer were considered (n = 556), the risk for breast cancer recurrence was nonsignificantly lower among the toremifene-treated women, with a hazards ratio of 0.74 (90% confidence interval, 0.52 to 1.04; P = .14). The mean time to breast cancer recurrence and overall survival were similar in both groups. CONCLUSION: The side-effect profile of toremifene resembles that of tamoxifen. The efficacy of toremifene seems to be no less than that of tamoxifen. The trend for fewer breast cancer recurrences in the ER-positive subgroup is encouraging, but a longer follow-up is needed to confirm this.

Background: Despite a growing use of rituximab (RTX) in neuromyelitis optica (NMO), data are lacking in patients with refractory NMO (RNMO), defined as cases with at least one relapse during immunosuppressive therapy. Objective: The purpose of this study was to assess RTX as a maintenance therapy in RNMO. Methods: Out of a total of 305 NMO cases from a population-based cohort, 21 RNMO patients received RTX during a mean follow-up period of 31 months. Results: After RTX, 11 patients (52.3%) were relapse free, meaning that 47.7% were refractory to RTX. The mean annualized relapse rate decreased from 1.3 to 0.4 ( p<0.001) and median EDSS from 5 to 3 ( p=0.02). Body mass index (BMI) was predictive of EDSS worsening. Conclusions: RTX is an effective and well-tolerated treatment in RNMO. BMI could be a predictive factor for efficacy.

In order to assess the risk of long-term complications following endoscopic sphincterotomy (ES) for common bile duct stones (CBDS), we conducted a cohort study. The study included 1,113 patients who underwent ES for CBDS in six different hospitals in central Sweden between 1977 and 1990. Through the use of the Swedish population registry, each patient was assigned five population-based controls matched for sex and age. Linkage to the Inpatient Registry yielded information on morbidity and mortality for the patients as well as for the controls. After one year of washout, there were 964 patients available for follow-up. The mean age was 70.6 years, 57% were women, and the mean length of follow-up was 8.9 years. The patients’ overall morbidity was significantly higher and we observed a tendency towards increased mortality as well. Recurrent CBDS was diagnosed in 4.1% of the patients. Acute cholangitis with a hazard ratio (HR) of 36 (95%CI 11–119.4) was associated with recurrent CBDS in 39% of the patients. HR for acute pancreatitis was 6.2 (95%CI 3.4–11.3) and only one patient had CBDS at the same time. In conclusion, we consider acute pancreatitis and cholangitis both as probable long-term complications after ES.

Incidence And Mortality

Background: Breast cancer (BC) incidence and mortality are lower in Poland than in the United States (US). However, Polish-born migrant women to US approach the higher BC mortality rates of US women. We evaluated the association between consumption of cabbage/sauerkraut foods and BC risk in Polish-born migrants to US. Methods: We conducted a case–control study of BC among Polish-born migrants in Cook County and the Detroit Metropolitan Area. Cases (n = 131) were 20–79 years old with histological/cytological confirmation of invasive BC. Population-based controls (n = 284) were frequency matched to cases on age and residence. Food frequency questionnaires assessed diet during adulthood and age 12–13 years. Odds ratios (OR) and 95% confidence intervals (95% CI) were estimated with conditional logistic regression. Consumption of total, raw/short-cooked, and long-cooked cabbage/sauerkraut foods was categorized as low, medium, or high (frequency of servings/week). Results: Higher consumption of total and raw/short-cooked cabbage/sauerkraut foods, during both adolescence and adulthood, was associated with a significantly lower BC risk. Consumption of long-cooked cabbage/sauerkraut foods was low and not significantly associated with risk. The multivariate OR for total cabbage/sauerkraut consumption, high vs. low (> 4 vs. ≤ 2 servings/week) during adolescence was 0.36 (95% CI = 0.18–0.71, ptrend < 0.01) and 0.50 (95% CI = 0.23–1.06, ptrend = 0.08) during adulthood. For raw/short-cooked cabbage/sauerkraut (>3 vs. ≤1.5 servings/week), the ORs were 0.35 (95% CI = 0.16–0.72, ptrend < 0.01) during adolescence and 0.37 (95% CI = 0.17–0.78, ptrend < 0.01) during adulthood. For joint adolescent/adult consumption of raw/short-cooked cabbage/sauerkraut foods, (high, high) vs. (low, low), the OR was 0.23 (95% CI = 0.07–0.65). The significant association for high adolescent consumption of raw/short-cooked cabbage/sauerkraut foods and reduced BC risk was consistent across all levels of consumption in adulthood. Conclusion: Greater consumption of total and raw/short-cooked cabbage/sauerkraut foods either during adolescence or adulthood was associated with significantly reduced BC risk among Polish migrant women. These findings contribute to the growing literature suggesting a protective effect of a potentially modifiable factor, cruciferous vegetable intake, on breast cancer risk.

Coronary Events

Background and Aims: Age-standardized rates of acute coronary events have been declining in all western countries. Concerns have been raised, however, that the absolute numbers of cases may be increasing due to the aging of the population. We examined trends in acute coronary events using data from the FINAMI myocardial infarction (MI) register. We also analyzed trends in coronary and other cardiac events in the whole country, using both age-standardized rates and crude numbers of cases to elucidate the effect of aging of the population. Methods: FINAMI is a population-based MI register, which aims at registering all MI events occurring in the populations aged 35 or over in five geographical areas of Finland. Hospital records, death certificates and other relevant documents were scrutinized and cases were classified to diagnostic categories as recommended by the AHA in 2003. To obtain information on the whole country we used record linkage of the National Hospital Discharge Register and Causes of Death Register. International Classification of Diseases (ICD-10) codes I20-I25 were taken as coronary events, for fatal cases we also included I46, R96 and R98. Other cardiac events consisted of ICD-10 codes I30-I52, thus including heart failure and arrhythmias. Annual population counts for the denominators were obtained from the National Population Information System. Event rates were age-standardized to the European Standard Population. Trends for the rates were estimated using Poisson regression and for crude numbers using linear regression. Results: The FINAMI MI register recorded 15,776 (13,248 men and 11,657 women) incident (=first) coronary events during the study period. In whole country, the corresponding numbers of first coronary events were 406,222 (221,838 in men and 184,383 in women). In FINAMI areas, the coronary mortality declined an average by 4.5% per year in men (P<0.0001) and 4.7% per year in women (p<0.0001). Declines in the incidence were smaller but also very significant: 1.6% and 1.8% per year in men and women, respectively (p<0.0001 for both). In country-wide data, declines in the age-standardized incidence were of the same order of magnitude as in the FINAMI areas and the crude numbers of cases also showed a declining trend: 0.4% per year in men (p=0.046) and 1.5% per year in women (p<0.0001). The age-standardized incidence of other cardiac events showed significant declines in both sexes, but the crude numbers of cases showed a modest increasing trend among men (1.1% per year, p=0.038) while no change was observed in women. Conclusions: Age-standardized incidence and mortality of coronary events continue to decline in Finland. The crude numbers of coronary events have also declined at least until 2007, despite the aging of the population. However, crude numbers of other first cardiac events, including heart failure and arrhythmias, showed a modest increasing trend among men.

Clinic Visits

Background: In Ontario, kidney transplants have risen by 4% annually in recent years. An understanding of how this will affect the future annual number of posttransplant follow-up visits informs how to organize and deliver care. Objective: We projected the required number of annual posttransplant follow-up nephrology visits to inform posttransplant care delivery. Design: Population-based retrospective cohort study. Setting: Linked databases from Ontario, Canada (population 14 million). Patients: Incident kidney transplant recipients from years 2008 to 2013. Measurements: Frequency, distance traveled, and current and projected visits for posttransplant follow-up. Methods: Assuming a graft survival of 13 years and using the mean number of posttransplant clinic visits in years 1, 2, and 3, we forecasted the number of clinic visits needed in the year 2027. Results: Using data from 2443 recipients, the mean (SD) number of clinic visits per recipient was 14.0 (9.2) in the first year after transplant, and 3.9 (6.2) and 3.0 (5.3) in the second and third year, respectively. If transplant rates rise by 4% per year until 2027, the estimated annual visits number will increase from 30 622 to 43 948. The median (25th, 75th percentile) distance between transplant center and patient’s home was 30 (13, 65) km. The median round-trip travel distance for these visits in the first year after transplantation was 603 km per recipient, and median driving cost was Can$344 (2017). Limitations: Regarding patient expense, limitations include that distances traveled were calculated orthodromically, and we did not account for patient cost of follow-up beyond that of vehicular travel. Regarding follow-up projections, limitations include the assumption that graft life span will not change, follow-up patterns do not differ between donor kidney type, and we did not survey stakeholders as to their preferred method of follow-up. Conclusion: We quantified the increase in posttransplant visits when regional annual rates of transplantation rise. Strategies recognizing the burden of these visits may enhance patient-centered care, as it is unclear how some patients manage costs, nor how the current health care system will manage the demand.
