Abbreviations: CTCAE v4.0, Common Terminology Criteria for Adverse Events, version 4.0; EIAC, endocrine therapy–induced alopecia after chemotherapy; NA, not applicable; pCIA, persistent chemotherapy-induced alopecia; SERM, selective estrogen receptor modulators.
Comparisons of pCIA and EIAC were performed using t test and Fisher exact test.
Patients with EIAC had full hair regrowth after cytotoxic chemotherapy.
Grade 1 is hair loss of less than 50% of normal for that individual and is not obvious from a distance but only on close inspection; it does not require camouflage. Grade 2 is hair loss of 50% or more of normal for that individual and is readily apparent to others; camouflage is necessary if the patient desires, and it is associated with negative psychosocial effects.
