Background Breast cancer in young adults is rare and accounts for 5 to 6% of all cancers in this age group. We conducted the present study to look at the demographic features, clinical presentation, and outcomes in this group of patients treated at our center.

Patients and Methods The study included breast cancer patients between the age of 15 and 30 years treated at our institute from January 2009 to December 2016. Data were analyzed retrospectively from case records. Event-free survival (EFS) and overall survival (OS) were calculated using the Kaplan–Meier method.

Results Young adult breast cancers were reported in 145 out of 6,000 patients (2.41%) diagnosed with breast cancer in the study period. The median age of the patients was 29 years (range: 21–30 years). Stage I, II, III, and IV was observed in 3.4, 33.7, 46.2, and 16.5% of patients, respectively. The median follow-up was 45 months (range: 1.7–128.1 months). The 5-year EFS and OS for stage I, II, III, and IV was 100, 74.5, 47.9, and 0% and 100, 90.8, 55.1, and 0%, respectively. On univariate analysis, stage of the disease and pregnancy-associated breast cancers were found to have a significant association with decreased EFS and OS (p < 0.001, p = 0.008 and p < 0.001, p = 0.001, respectively). On multivariate analysis, stage of disease and pregnancy-associated breast cancers remained significant predictors of EFS and OS.

Conclusion Breast cancers in young adults are rare but need to be diagnosed at an early stage to improve survival. Pregnancy-associated breast cancers need to be managed optimally without delay owing to their aggressive tumor biology.

Study Design and Ethics

Retrospective analysis of patient case records do not require formal ethics approval at our institute. The study was conducted according to the criteria set by the Declaration of Helsinki. Written informed consent was obtained from all patients before starting the planned treatment.
