Methods Interval cancer rate and characteristics were analyzed in the Cór­doba Breast Tomosynthesis Screening Trial (CBTST) study population and compared with a contemporary DM control population. Tumor features of screen-detected and interval cancers were contrasted using contingency tables, chi-square/Fisher’s exact tests, and Student’s t/Mann–Whitney U tests. Results Among 16,068 DBT+DM exams and 23,787 DM-only screens, interval cancer rate was lower with DBT+DM (15‰ vs 43‰; p=0.045), with a larger difference in dense breasts. Interval cancers were smaller with DBT+DM (p=0.031). Conclusions DBT+DM screening reduced interval cancer rate versus DM alone, especially in women with dense breasts; greatest clinical relevance was observed for dense-breast subgroups.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/research-report/","Research

Methods The interval cancer rate and interval cancer characteristics of the study population included in the Cór‑ doba Breast Tomosynthesis Screening Trial (CBTST) were compared to a contemporary control population screened with DM. The tumour characteristics of screen‑detected and interval cancers were also compared. Contingency tables were used to compare interval cancer rates. The chi‑square test and Fisher’s exact test were used to compare the qualitative characteristics of the cancers whereas Student’s t test and the Mann–Whitney U test were used to ana‑ lyse quantitative features.  \nResults A total of 16,068 screening exams with DBT + DM were conducted within the CBTST (mean age 57.59 ± 5.9 [SD]) between January 2015 and December 2016 (study population) . In parallel, 23,787 women (mean age 58.89 ± 5.9 standard deviation [SD]) were screened with DM (control population) . The interval cancer rate was lower in the study population than in the control population (15 [0 . 93‰; 95% confidence interval (CI): 0 . 73, 1. 14] vs 43 [1 . 8‰; 95% CI: 1. 58, 2 . 04] respectively; p = 0 . 045) . The difference in rate was more marked in women with dense breasts (0 . 95‰ in the study population vs 3. 17‰ in the control population; p = 0 . 031) . Interval cancers were smaller in the study population than in the control population (p = 0 . 031) .  \nConclusions The interval cancer rate was lower in women screened with DBT + DM compared to those screened with DM alone. These differences were more pronounced in women with dense breasts.  \nClinical relevance statement Women screened using tomosynthesis and digital mammography had a lower rate of interval cancer than women screened with digital mammography, with the greatest difference in the interval can‑ cer rate observed in women with dense breasts.  \n*Correspondence: Cristina Pulido‑Carmona [kris_fn@hotmail.com](kris_fn@hotmail.com)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2024.
