Abstract PS2-06-16: Two cohorts of young women (41y at diagnosis) with invasive breast cancer: Single center data on how demographics, tumor characteristics, therapies and 5-year survival differ when treated 2000-2005 and 2014-2019
Retrospective analysis compares demographics and outcomes in young women with breast cancer, showing significant improvements over 19 years.
Key Points
To compare demographics, tumor characteristics, therapies, and 5-year survival rates among young women with invasive breast cancer diagnosed before age 41 across two time periods.
Retrospective comparison of two cohorts diagnosed between 2000-2005 and 2014-2019
Analysis included demographics, tumor characteristics, therapies, and survival outcomes
Continuous variables were analyzed using Mann-Whitney U test; categorical variables using Fisher’s exact test
Cohort 1 had 233 patients; cohort 2 had 237 patients, with no significant age difference at diagnosis
Cohort 2 showed significantly higher rates of screening detection and neoadjuvant therapy
5-year disease-free and distant relapse-free survival significantly improved from cohort 1 to cohort 2
