Background: Retrospective studies suggest that breast cancer survivors report treatment-associated hair loss or thinning years after their initial diagnosis. This study investigates patient perceptions of alopecia persisting 6 years after the diagnosis of breast cancer. Methods: Breast cancer survivors who had signed informed consent for participation in a prospective longitudinal cohort study, the Mayo Clinic Breast Disease Registry (MCBDR), after diagnosis of breast cancer approximately six years prior, were mailed a survey. This survey asked about degree of bother from hair thinning and hair loss on a scale from 0 “not at all” to 4 “extremely” and about use of hair thickening/regrowth products. PROMIS-10 project scales assessed global mental health (5: worst mental health, 20: best mental health). Data were analyzed using descriptive statistics. Results: 969/1476 participants responded (response rate 65.7%); 819 participants were available for analysis. Participant median age was 65.7 years (range 34 -100 years). 604 (73%) had been diagnosed with stage I-II breast cancer, 248 (30%) had received chemotherapy (+/- endocrine therapy), 365 (45%) had received only endocrine therapy, and 206 (25%) had received neither. Nearly half (381, 47%) reported hair loss and over half (468, 57%) reported hair thinning. 155 (19%) used hair regrowth products. Amongst the 526 who were 55 years and older, 270 (51%) reported hair loss and 323 (61%) hair thinning; 111 (38%) of the 291 women under 55 years reported hair loss and 145 (50%) hair thinning. Twenty-eight percent of chemotherapy recipients, 18% of patients who did not receive chemotherapy but received endocrine therapy, and 14% of patients who had received neither reported continued difficulty with moderate to extreme hair loss. Moderate to extreme bother from hair thinning was reported by 34% of chemotherapy recipients, 22% of endocrine therapy-only recipients, and 18% of those who had received neither. See the table for associations between mental health scores and hair loss/thinning. Use of hair growth products was reported by 29% of chemotherapy recipients, 14% of endocrine therapy-only recipients, and 15% of those who had received neither oncologic therapy. Conclusions: Hair loss and thinning are frequently reported as persistently bothersome symptoms from breast cancer survivors. Future investigations into the incidence, predictors, and treatment of chemotherapy and endocrine therapy-associated alopecia are needed.
