BACKGROUND: The Sonic hedgehog (Shh) gene is involved in the initiation of hair growth. We have shown that localized, transient, enhanced expression of the Shh gene in mouse skin mediated by an adenovirus (AdShh) vector accelerates initiation of the anagen (i.e., growth) phase of hair follicle development. Because hair regrowth in chemotherapy-induced alopecia is associated with follicle cell proliferation and active melanogenesis similar to that observed in the anagen phase of normal hair growth, we examined whether AdShh-mediated Shh expression would accelerate hair regrowth in the skin of mice with chemotherapy-induced alopecia.
METHODS: After establishment of cyclophosphamide-induced alopecia, in either 3- or 7-week-old mice, AdShh or a control vector (AdNull) was delivered to dorsal skin by intradermal injection. Hair regrowth and melanogenesis were assessed by histology and gross morphology. Fisher's exact test was used to compare differences in outcomes between AdShh-treated and control (AdNull-treated or not injected with any vector [naive]) mice. All statistical tests were two-sided.
RESULTS: Northern blot analysis confirmed enhanced Shh expression after AdShh administration in 7-week-old mice. Two weeks after AdShh administration, the injection site (all of five mice) showed large, anagen-phase hair follicles with a normal distribution of melanin. In contrast, both skin treated with AdNull (all of five mice) and skin from naive mice (all of five mice) showed dystrophic hair follicles with irregular distribution of melanin (P<.001 in both comparisons). Gross morphologic observations confirmed that AdShh-treated mice, but not naive mice or AdNull-treated mice, showed skin darkening at the injection site indicative of entry into anagen phase (P<.001 in both comparisons). AdShh treatment of 3-week-old mice with cyclophosphamide-induced alopecia was followed by accelerated hair follicle recovery (19 of 22 mice); such recovery was not observed at this rate in AdNull-treated or naive skin (P<.001 for both comparisons).
CONCLUSION: Localized, transient, enhanced expression of Shh gene in skin, mediated by an adenovirus vector, might be a future strategy to accelerate hair follicle regrowth after chemotherapy-induced alopecia.

BACKGROUND: To analyze the clinical and histological features of permanent alopecia following a sequential fluorouracil/epirubicin/cyclophosphamide (FEC) and docetaxel regimen for adjuvant breast cancer treatment.
PATIENTS AND METHODS: Women treated for breast cancer by a sequential adjuvant FEC and docetaxel regimen who developed permanent alopecia diagnosed between 2007 and 2011 were identified from the Department of Dermatology (Saint-Eloi Hospital, Montpellier, France) and the Department of Medical Oncology (CRLC Val d'Aurelle, Montpellier, France). Data were collected regarding demographics, type of cancer, delay of onset after chemotherapy, Dermatology Life Quality Index (DLQI), clinical description of the lesions, scalp biopsies, laboratory explorations investigating steroid hormonal, iron, zinc and thyroid status, therapy and outcome.
RESULTS: Twenty white Caucasian females were included. Hair loss presented with a moderate or intense androgenetic-like pattern of scalp alopecia. Biopsy specimen examinations were normal or displayed theandrogenetic-like pattern. Laboratory explorations ruled out iron or zinc deficiency and thyroid disorders and confirmed hormonal menopause without hyperandrogenism. The overall mean DLQI score reflected the distressing psychological consequences in the patients' lives. No spontaneous regrowth of the scalp hair was noted. Treatment including vitamins, minoxidil, psoralen and ultraviolet A therapy and spironolactone proved to be ineffective.
CONCLUSION: Permanent and severe alopecia is a newly reported complication of the FEC 100-docetaxel breast cancer regimen.
