ObjectivesTo evaluate the factors related to breast cancer (BC) recurrence as well as survival in women ≤40 years old.MethodsThis is a retrospective medical record review of women aged ≤40 years diagnosed with BC stages I to III between January 2009 and June 2017 at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia. Demographic data collected included patients' initial presentation (including age and date of diagnosis), imaging studies, tumor characteristics, type of surgery, systemic therapy (if any) received, and site of first recurrence. Data was analyzed to assess recurrence rate, disease-free survival (DFS), and overall survival (OS), and determine associated factors. Descriptive statistics were used to calculate the mean, median, standard deviation, and quartiles. Chi-square test was performed to test the association between 2 variables. Kaplan-Meier analyses were performed to assess survival distribution.ResultsA total of 117 patients were included for analysis. Median follow-up was 16 months (range 0 to 99). Five-year DFS 57% and OS was 89%. Adjuvant chemotherapy was associated with a better DFS (hazard ratio of 0.204; 95% confidence interval, 0.050 to 0.832; p=0.027). Higher tumor, node, metastasis stage was significantly associated with worse DFS (p=0.034). Fewer postoperative follow-up visits signi cantly predicted recurrence (p=0.003).ConclusionWe found a high risk of BC recurrence among patients at our institution. Higher cancer stage, nonuse adjuvant chemotherapy, and low follow-up rate were significant predictive factors for recurrence.
