“…13 This figure corroborates the hypothesis that the increase in the incidence of breast cancer, particularly in the age group from 40 to 59 years, may be partially explained by the implementation of population screening programs using mammography. Through these, subclinical lesions that perhaps would not have become clinically detectable, until the patient's death due to some other cause, can be diagnosed.…”

“…In Brazil, the incidence and mortality rates of BC are relatively high (9,10). Compared with North America, where the incidence of BC among younger women has plateaued (11), Brazil continues to present with relatively high incidence rates among women aged 30–39 years (12).…”

Retrospective analysis of breast cancer prognosis among young and older women in a Brazilian cohort of 738 patients, 1985–2002

Invasive breast cancer (BC) is infrequent among women aged ≤40 years, however, the disease outlook in these younger patients is generally worse than among older women. The present study aimed to compare socio-demographic, clinical and pathological characteristics, and their association with long-term survival, between two random cohorts of young (≤40 years) and older (50–69 years) Brazilian patients with BC. The cohort comprised of 738 randomly selected women who were diagnosed with BC at Barretos Cancer Hospital, Pio XII Foundation (Barretos, Brazil) between January 1985 and December 2002; the patients included young women (n=376) and older women (n=362). The current analysis suggested that BC in young women is associated with numerous pathological features of aggressiveness. Second cancer and bilateral BC were independent predictors of a poor outcome in the younger group. Furthermore, C-erB-2 was positively correlated with poor outcome in the older group, whereas estrogen receptor status and TNM stage were associated with disease prognosis in both groups. The overall survival rates of the two age groups were similar except when analyzed according the treatment period (1997–2002). Although patients aged ≤40 years harbored tumors with more aggressive clinicopathological characteristics, these characteristics were not independent predictors of overall survival. The present study indicates that medical advances associated with prevention of breast cancer may improve screening programs, which may therefore increase early diagnosis and subsequently lower mortality rates.

“…20 Therefore, one of the hypotheses raised to explain the increase in breast cancer incidence is that early diagnosis is now occurring, as has been observed in epidemiological studies on this type of neoplasia. 13,14,21 It can be asked whether this same hypothesis would explain the increase in prevalence observed in the present study, which grew from 22.87/100,000 women in 1988 to 220.22/100,000 women in 2002,…”

CONTEXT AND OBJECTIVE: Studies have shown increased prevalence rates for breast cancer, relating to higher incidence, longer survival and breast cancer prevention programs among populations. The aim here was to analyze the annual prevalence of breast cancer in Goiânia over a 15-year period. DESIGN AND SETTING: This was a cross-sectional study on women with breast cancer diagnosed in Goiânia, Goiás, Brazil, from 1988 to 2002. METHODS: The breast cancer cases were identified in the database of the Population-Based Cancer Registry of Goiânia. The 15-year period was stratified into three five-year periods. The cases were followed up for five years, and the mortality database was used to exclude deaths. The population of the official census was used as the denominator for rate calculations. RESULTS: The coefficient of breast cancer prevalence in Goiania was 22.87/100,000 in 1988 and 220.22/100,000 women in 2002. The analyses for periods showed that in the first period, the rate was 19.39/100,000 and that it was 44.79/100,000 in the last period. For the fifteen years analyzed, the prevalence rate for breast cancer was 127.24/100,000 women. The annual percentage change was 27.07 (P < 0.001; 95% confidence interval, CI: 20.79-33.67) from 1988 to 1992 and 9.39 (P < 0.001; 95% CI: 8.52-10.25) from 1992 to 2002. CONCLUSION: There was an increase in the breast cancer prevalence rate in the city of Goiânia between 1988 and 2002, possibly relating to the improvement in the screening and treatment of breast cancer
