Logistic regression models were used in case–case analyses to estimate associations between epidemiological risk factors and tumor subtypes, and case–control analyses to estimate associations between epidemiological risk factors and the risk of developing specific tumor subtypes in 12 population-based studies. All statistical tests were two-sided.</p></sec><sec><title>Results</title><p>In case–case analyses, of the epidemiological risk factors examined, early age at menarche (≤12 years) was less frequent in case patients with PR<sup>−</sup> than PR<sup>+</sup> tumors (<italic>P</italic> = .001). Nulliparity (<italic>P</italic> = 3 × 10<sup>−6</sup>) and increasing age at first birth (<italic>P</italic> = 2 × 10<sup>−9</sup>) were less frequent in ER<sup>−</sup> than in ER<sup>+</sup> tumors. Obesity (body mass index [BMI] ≥ 30 kg/m<sup>2</sup>) in younger women (≤50 years) was more frequent in ER<sup>−</sup>/PR<sup>−</sup> than in ER<sup>+</sup>/PR<sup>+</sup> tumors (<italic>P</italic> = 1 × 10<sup>−7</sup>), whereas obesity in older women (>50 years) was less frequent in PR<sup>−</sup> than in PR<sup>+</sup> tumors (<italic>P</italic> = 6 × 10<sup>−4</sup>). The triple-negative (ER<sup>−</sup>/PR<sup>−</sup>/HER2<sup>−</sup>) or core basal phenotype (CBP; triple-negative and cytokeratins [CK]5/6<sup>+</sup> and/or epidermal growth factor receptor [EGFR]<sup>+</sup>) accounted for much of the heterogeneity in parity-related variables and BMI in younger women. Case–control analyses showed that nulliparity, increasing age at first birth, and obesity in younger women showed the expected associations with the risk of ER<sup>+</sup> or PR<sup>+</sup> tumors but not triple-negative (nulliparity vs parity, odds ratio [OR] = 0.94, 95% confidence interval [CI] = 0.75 to 1.19, <italic>P</italic> = .61; 5-year increase in age at first full-term birth, OR = 0.95, 95% CI = 0.86 to 1.05, <italic>P</italic> = .34; obesity in younger women, OR = 1.36, 95% CI = 0.95 to 1.94, <italic>P</italic> = .09) or CBP tumors.</p></sec><sec><title>Conclusions</title><p>This study shows that reproductive factors and BMI are most clearly associated with hormone receptor–positive tumors and suggest that triple-negative or CBP tumors may have distinct etiology.</p></sec></div></front></TEI><pmc article-type="research-article"><pmc-comment>The publisher of this article does not allow downloading of the full text in XML form.</pmc-comment>

Logistic regression models were used in case–case analyses to estimate associations between epidemiological risk factors and tumor subtypes, and case–control analyses to estimate associations between epidemiological risk factors and the risk of developing specific tumor subtypes in 12 population-based studies. All statistical tests were two-sided.</p></sec><sec><title>Results</title><p>In case–case analyses, of the epidemiological risk factors examined, early age at menarche (≤12 years) was less frequent in case patients with PR<sup>−</sup> than PR<sup>+</sup> tumors (<italic>P</italic> = .001). Nulliparity (<italic>P</italic> = 3 × 10<sup>−6</sup>) and increasing age at first birth (<italic>P</italic> = 2 × 10<sup>−9</sup>) were less frequent in ER<sup>−</sup> than in ER<sup>+</sup> tumors. Obesity (body mass index [BMI] ≥ 30 kg/m<sup>2</sup>) in younger women (≤50 years) was more frequent in ER<sup>−</sup>/PR<sup>−</sup> than in ER<sup>+</sup>/PR<sup>+</sup> tumors (<italic>P</italic> = 1 × 10<sup>−7</sup>), whereas obesity in older women (>50 years) was less frequent in PR<sup>−</sup> than in PR<sup>+</sup> tumors (<italic>P</italic> = 6 × 10<sup>−4</sup>). The triple-negative (ER<sup>−</sup>/PR<sup>−</sup>/HER2<sup>−</sup>) or core basal phenotype (CBP; triple-negative and cytokeratins [CK]5/6<sup>+</sup> and/or epidermal growth factor receptor [EGFR]<sup>+</sup>) accounted for much of the heterogeneity in parity-related variables and BMI in younger women. Case–control analyses showed that nulliparity, increasing age at first birth, and obesity in younger women showed the expected associations with the risk of ER<sup>+</sup> or PR<sup>+</sup> tumors but not triple-negative (nulliparity vs parity, odds ratio [OR] = 0.94, 95% confidence interval [CI] = 0.75 to 1.19, <italic>P</italic> = .61; 5-year increase in age at first full-term birth, OR = 0.95, 95% CI = 0.86 to 1.05, <italic>P</italic> = .34; obesity in younger women, OR = 1.36, 95% CI = 0.95 to 1.94, <italic>P</italic> = .09) or CBP tumors.</p></sec><sec><title>Conclusions</title><p>This study shows that reproductive factors and BMI are most clearly associated with hormone receptor–positive tumors and suggest that triple-negative or CBP tumors may have distinct etiology.</p></sec></abstract></article-meta></front></pmc></record>Pour manipuler ce document sous Unix (Dilib)
