Background: Cancer is one of the most important causes of death in the world and has an increasing trend globally. We aimed at investigating the five leading cancers in Iranian women based on a 10-year history of cancer registry reports and illustrating the trends in all cancer sites and breast cancer as the top leading one from 2003 to 2015. Methods: Data were obtained from national cancer registry study. Age-Specific Incidence Rate (ASR) data were obtained from Iran’s annual national cancer registry reports between 2003 to 2010 and 2014 to 2015. Using Joinpoint regression, we analyzed incidence trends over time for all cancer sites and the top leading cancer from 2003 to 2015. Results: Breast cancer was ranked first in Iranian women. Its ASR raised from 15.96 in 2003 to 32.63 in 2015. Results of trend analysis based on Annual Percent Change (APC) index showed 5.6 (95%CI: 2.9 to 8.3) and 4.6 (95%CI: 2.0 to 7.2) annual increase in the incidence of all cancer sites and breast cancer from 2003 to 2015, respectively. Conclusion: This study indicates significant increasing trends in all cancer sites and breast cancer incidence in Iran. Despite the national coverage of cancer registry over the past decade, more considerations should be taken into account, especially in Breast cancer.

Background: Uruguay is the southamerican country which has the highest cancer incidence and mortality rates. The National Cancer Registry collects data on cancer cases nationwide since 1989 and has reached high quality standards in the last decades. This is the first report on incidence trends. Methods: Data from the National Cancer Registry of all new cases of invasive cancer from twelve sites diagnosed in 2002-2015 was analyzed. Age-standardized rates were calculated. Trends of incidence rates were analyzed using joinpoint regression models. Results For both, men and women, incidence rates trends for all cancer sites, colo-rectal and bladder cancer remained stable. Esophageal and gastric cancers descend while Thyroid and kidney cancer incidence increased. In men lung cancer decreased; testicular cancer increased, and prostate cancer increased at the beginning of the period and decreased in the final years. In women; lung cancer increased, breast cancer remained stable and cervical cancer presented a significant decline from 2005 to 2010 and reached a plateau since then. Conclusion: Cancer incidence dynamics are complex and affected not only by Public Health policies such as tobacco control, vaccination and screening programs, but also by environmental and life style changes and the attitude of the medical community towards the application of diagnostic and therapeutic tools. The aim of this paper is to analyze cancer incidence time trends in the country and provide possible explanations to them.

Cancer Incidence Rates

Background. This study was undertaken to evaluate trends in breast cancer incidence in Egypt from 1999 to 2008 and to make projections for breast cancer occurrence for the years 2009–2015.Patients and Methods. We utilized joinpoint regression and average annual percent change (AAPC) measures with 95% confidence intervals (CI) to describe the trends in breast cancer incidence rates from the Gharbiah Cancer Registry by age and stage at diagnosis and to estimate expected breast cancer caseloads for 2009–2015.Results. From 1999 to 2008, the AAPC in breast cancer incidence rates in Gharbiah significantly increased among women 50 years and older and among localized tumors (AAPC %, 95% CI, 3.1% to 8.0%). Our results predict a significant increase in breast cancer caseloads from 2009 to 2015 among women aged 30–39 (AAPC %, 95% CI, 0.9% to 1.1%) and among women aged 40–49 years (AAPC %, 95% CI, 1.0% to 2.6%).Conclusion. These results have important implications for allocating limited resources, managing treatment needs, and exploring the consequences of prior interventions and/or changing risk factors in Egypt and other developing countries at the same stages of demographic and health transitions.

Registration Data

Objective Fluctuations in the incidence of breast cancer in Norway in the last three decades are partly explained by the use of hormone replacement therapy and mammography screening, but overdiagnosis has also been suggested as a cause. We assessed the trends in breast cancer incidence and overdiagnosis in Norway. Methods We calibrated our microsimulation model to Norwegian Cancer Registration data. The model takes into account the use of mammography (both within and outside the Norwegian Breast Cancer Screening Programme) and of hormone replacement therapy. We obtained a proper fit of breast cancer incidence in recent years, when assuming an increase in the background risk for breast cancer, and estimated overdiagnosis. Results We estimated a 2% overdiagnosis rate as a fraction of all cancers diagnosed in women aged 50–100, and a 3% overdiagnosis rate as a fraction of all cancers diagnosed in women aged 50–70 (i.e. screening age). If all of the increased incidence would be the result of the detection of slow growing tumours, these estimates were 7% and 11%, respectively. Conclusion Besides mammography and hormone replacement therapy use, additional risk factors contributed to the sudden increase in breast cancer incidence in Norway. Overdiagnosis estimates due to screening were within the range of international plausible estimates.

The Impact

Objective To investigate the impact of population mammography screening on breast cancer incidence trends in New Zealand. Methods Trends in age-specific rates of invasive breast cancer incidence (1994–2014) were assessed in relation to screening in women aged 50–64 from 1999 and 45–69 following the programme age extension in mid-2004. Results Breast cancer incidence increased significantly by 18% in women aged 50–64 compared with 1994–98 (p<0.0001), coinciding with the 1999 introduction of mammography screening, and remained elevated for four years, before declining to pre-screening levels. Increases over 1994–99 incidence occurred in the 45–49 (21%) and 65–69 (19%) age groups following the 2004 age extension (p<0.0001). Following establishment of screening (2006–10), elevated incidence in the screening target age groups was compensated for by lower incidence in the post-screening ⩾70 age groups than in 1994–98. Incidence in women aged ⩾45 was not significantly higher (+5%) after 2006 than in 1994–98. The cumulated risk of breast cancer in women aged 45–84 for 1994–98 was 10.7% compared with 10.8% in 2006–10. Conclusions Increases in breast cancer incidence following introduction of mammography screening in women aged 50–64 did not persist. Incidence inflation also occurred after introduction of screening for age groups 45–49 and 65–69. The cumulated incidence for women aged 45–84 over 2006–10 after screening was well established, compared with 1994–98 prior to screening, shows no increase in diagnosis. Over-diagnosis is not inevitable in population mammography screening programmes.

AbstractBackgroundStrategies for breast cancer prevention are informed by assessing whether incidence differs by tumour biology. We describe temporal trends of breast cancer incidence by molecular subtypes in Scotland.MethodsPopulation-based cancer registry data on 72,217 women diagnosed with incident primary breast cancer from 1997 to 2016 were analysed. Age-standardised rates (ASR) and age-specific incidence were estimated by tumour subtype after imputing the 8% of missing oestrogen receptor (ER) status. Joinpoint regression and age- period- cohort models were used to assess whether significant differences were observed in incidence trends by ER status.ResultsER positive tumour incidence steadily increased particularly for women of screening age 50 to 69 years from 1997 till around 2011 (1.6%/year, 95%CI: 1.2 to 2.1). ER negative incidence decreased among all ages at a consistent rate of −0.7%/year (95%CI: −1.5, 0) from around 2000-2016. Compared to the 1941-1959 central birth cohort, women born 1912-1940 had lower incidence rate ratios (IRR) for ER+ tumours and women born 1960- 1986 had higher IRR for ER- tumours.ConclusionsWe show evidence of aetiologic heterogeneity of breast cancer. Future incidence and survival reporting should be monitored by molecular subtypes.
