Incidence Trend

CONTEXT AND OBJECTIVE: It has been suggested that there has been a large increase in breast cancer incidence among young women over the last decade. The aim of this study was to describe the incidence of breast cancer among young women up to 39 years of age in Goiânia, between 1988 and 2003, and to compare this with other age groups. DESIGN AND SETTING: Retrospective study using the database of the Population-based Cancer Registry of Goiânia, State of Goiás, Brazil. METHODS: The incidence was calculated according to age groups: up to 39 years, 40 to 59 years and 60 years and over. Average annual percentage changes (AAPCs) were estimated for the different age groups using Poisson regression. RESULTS: Over this period, 3,310 new cases were recorded. The standardized incidence was 2.89/100,000 in 1988 and increased to 6.37/100,000 in 2003 (R² = 0.52) for the group aged up to 39 years (p < 0.003). For the group from 40 to 59 years old, the incidence was 14.39/100,000 in 1988 and 41.70/100,000 in 2003 (R² = 0.85; p < 0.001). For the group aged 60 years and over, it was 17.62/100,000 and 28.49/100,000, respectively (R² = 0.67; p < 0.001). The AAPCs were 5.22%, 5.53% and 4.54% for the age groups up to 39, 40 to 59 and 60 years and over, respectively. CONCLUSIONS: The incidence of breast cancer among young women in Goiânia has been increasing significantly, although this change was similar to the increase in other age groups.

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.

e13099 Background: Reports on delay to diagnosis of cancer in young women are based on retrospective studies and conflicting. The purpose of this study was to investigate time to cancer diagnosis in women presenting to a surgeon with breast-related complaints; and particularly, the role of age. Methods: A population-based cohort study including all women aged 18 to 44 presenting to a surgeon with a breast-related complaint between 2005 and 2015 in a large Israeli healthcare plan (N = 157,264). We collected data including demographics, diagnosis codes, breast imaging and biopsies. Breast cancer diagnosis within one year of the visit was ascertained from the national cancer registry. Time to breast imaging and biopsy was compared between the different age groups. Logistic regression analysis was used to determine the association between age and delay to biopsy while adjusting for possible confounders. Results: During the first year after the visit, 45,434 (29%) women had a breast imaging study; 5,767 (3.7%) women had a breast biopsy; and 676 (0.43%) were diagnosed with breast cancer. Overall, time to first breast imaging (mean, 53 days) and biopsy (mean, 68 days) did not differ significantly between the age groups. Non-specific visit codes (other than breast mass) were associated with delays to imaging and biopsy. This was more pronounced in the women ultimately diagnosed with breast cancer. Among women diagnosed with breast cancer, age under 40 (OR 2.3, 95% CI 1.4; 3.9), being post-partum (OR 2.6, 95% CI 1.1; 5.9) and a non-specific visit code (OR-8.3, 95% CI 4.9; 14.2) were associated with delay to biopsy. Conclusions: Symptomatic women with lower a-priori likelihood of breast malignancy (younger age, post-partum, or non-specific visit code) are at a significantly greater risk of delayed diagnosis of cancer. Physicians should be aware of the challenging diagnosis in young women with non-specific symptoms.
