Cyclophosphamide induced alopecia

M K Fehr, J Welter, W Sell, R Jung, R Felberbaum
BACKGROUND: Scalp cooling has been used since the 1970s to prevent chemotherapy-induced alopecia, one of the most common and psychologically troubling side effects of chemotherapy. Currently available scalp cooling systems demonstrate varying results in terms of effectiveness and tolerability. METHODS: For the present prospective study, 55 women receiving neoadjuvant, adjuvant, or palliative chemotherapy were enrolled. The aim was to assess the effectiveness of a sensor-controlled scalp cooling system (DigniCap: Sysmex Europe GmbH, Norderstedt, Germany) to prevent chemotherapy-induced alopecia in breast or gynecologic cancer patients receiving 1 of 7 regimens...

Although numerous hypotheses have been proposed to prevent chemotherapy-induced alopecia (CIA), effective pharmaceuticals have yet to be developed. In our study, the back hairs of C57BL/6 mice were factitiously removed. These mice were then treated with cedrol or minoxidil daily. Mice with early-stage anagen VI hair follicles were treated with cyclophosphamide (CYP, 125mg/kg) to induce alopecia. The CYP-damaged hair follicles were observed and quantified by using a digital photomicrograph. The results demonstrated that the minoxidil-treated mice suffered from complete alopecia similar to the model 6days after CYP administration...

BACKGROUND: Chemotherapy-induced alopecia (CIA) is one of the most distressing side effects for patients undergoing chemotherapy. This study evaluated the protective effect of Korean Red Ginseng (KRG) on CIA in a well-established in vitro human hair follicle organ culture model as it occurs in vivo. METHODS: We examined whether KRG can prevent premature hair follicle dystrophy in a human hair follicle organ culture model during treatment with a key cyclophosphamide metabolite, 4-hydroperoxycyclophosphamide (4-HC)...

BACKGROUND: Standard prophylaxis for chemotherapy-induced nausea and vomiting (CINV) with highly emetogenic and anthracycline-cyclophosphamide-based chemotherapy includes a 5-hydroxytryptamine-3 receptor antagonist, a neurokinin-1 receptor antagonist (NK1RA), and corticosteroid therapy. NEPA is a fixed combination of netupitant and palonosetron. The primary objective of this analysis was to document the safety profile, including cardiac safety, of NEPA + dexamethasone in comparison with current therapies across all phase II/III trials...

Topically applied vasoconstrictor is a new strategy to prevent oral mucositis and alopecia, two complications of chemotherapy and stem-cell transplant. We sought to determine whether mice treated with topical vasoconstrictor minutes before chemotherapy to suppress L1210 leukemia would develop a vasoconstrictor-induced L1210 cell sanctuary, and with it, significantly worse survival outcomes. B6D2F1 mice received 10(4) mouse L1210 leukemia cells via retro-orbital intravenous injection and were then divided into treatment groups, which included: (i) no further treatment, (ii) a single, sub-curative, intraperitoneal dose of cyclophosphamide (90 µg/gm bw) 24 hr after L1210 cell inoculation, (iii) topical epinephrine (25-400 mM) to clipped dorsal backs 20 min before cyclophosphamide or (iv) orotopical phenylephrine (16-130 mM), epinephrine (10 mM) or norepinephrine (25 mM) 20 min before cyclophosphamide...

Optimized research models are required to further understand the pathogenesis and prophylaxis of chemotherapy-induced alopecia. Our aim was to develop a mouse model for chemotherapy-induced alopecia by follicular unit transplantation of human hair follicles onto immunodeficient mice. Twenty-two weeks after transplantation, a single dose of cyclophosphamide (Cph) was administered to mice in the Cph100 (100 mg/kg) and Cph150 (150 mg/kg) groups. On day 6, hair follicles showed dystrophic changes, with swollen dermal papilla and ectopic melanin clumping in the hair bulb...

BACKGROUND: The influence of systemic comorbidities on the success of scalp cooling during chemotherapy (CT) is widely unexplored. Comorbidities often require additional medication which itself can occasionally cause alopecia. This study investigates the influence of selected parameters on the efficacy of scalp cooling for the prevention of CT-induced alopecia. PATIENTS AND METHODS: 226 cancer patients were treated with various CT regimens in combination with sensor-controlled scalp cooling...

BACKGROUND: Chemotherapy-induced alopecia (CIA) is a distressing adverse effect of many chemotherapy agents. The TC (docetaxel [Taxotere] and cyclophosphamide) chemotherapy regimen is typically associated with complete alopecia. Scalp cooling with cold caps has been reported to minimize or prevent CIA. We conducted a prospective study to assess efficacy of scalp cooling in preventing CIA among women receiving adjuvant TC chemotherapy for breast cancer. METHODS: Women at the Weill Cornell Breast Center who independently elected to use scalp cooling with cold caps during adjuvant TC chemotherapy were asked to participate...

Parathyroid hormone (PTH) and parathyroid hormone-related protein (PTHrP) influence hair follicles through paracrine and intracrine routes. There is significant evidence that PTH and PTHrP influence the proliferation and differentiation of hair follicle cells. The PTH/PTHrP receptor signalling plays an important role in the hair follicle cycle and may induce premature catagen-telogen transition. Transgenic mice with an overexpression or blockade (PTH/PTHrP receptor knockout mice) of PTHrP activity revealed impaired or increased hair growth, respectively...

Chemotherapeutic agents induce complex tissue responses in vivo and damage normal organ functions. Here we use the feather follicle to investigate details of this damage response. We show that cyclophosphamide treatment, which causes chemotherapy-induced alopecia in mice and man, induces distinct defects in feather formation: feather branching is transiently and reversibly disrupted, thus leaving a morphological record of the impact of chemotherapeutic agents, whereas the rachis (feather axis) remains unperturbed...

A highly distressing side-effect of cancer chemotherapy is chemotherapy-induced alopecia (CIA). Scalp cooling remains the only treatment for CIA, yet there is no experimental evidence to support the cytoprotective capacity of cooling. We have established a series of in vitro models for the culture of human keratinocytes under conditions where they adopt a basal, highly-proliferative phenotype thus resembling the rapidly-dividing sub-population of native hair-matrix keratinocytes. Using a panel of chemotherapy drugs routinely used clinically (docetaxel, doxorubicin and the active metabolite of cyclophosphamide 4-OH-CP), we demonstrate that although these drugs are highly-cytotoxic, cooling can markedly reduce or completely inhibit drug cytotoxicity, in agreement with clinical observations...

Chemotherapy-induced alopecia is a major source of psychological stress in patients undergoing cancer chemotherapy, and it can influence treatment decisions. Although there is currently no therapy for alopecia, a fusion protein of parathyroid hormone and collagen binding domain (PTH-CBD) has shown promise in animal models. The aim of this study was to determine whether there are dose-dependent effects of PTH-CBD on chemotherapy-induced alopecia in a mouse model. C57BL/6J mice were waxed to synchronize hair follicles; treated on day 7 with vehicle or PTH-CBD (100, 320, and 1000 mcg/kg subcutaneous injection); and treated on day 9 with vehicle or cyclophosphamide (150 mg/kg intraperitoneally)...

BACKGROUND: Identification and development of drugs that can effectively modulate the therapeutic efficacy and toxicity of chemotherapy remain an unmet challenge. We evaluated the effects of Se-methylselenocysteine (MSC) on the toxicity and antitumour activity of cyclophosphamide, cisplatin, oxaliplatin, and irinotecan in animal models. METHODS: Cyclophosphamide, cisplatin, and oxaliplatin were administered by a single i.v. injection and irinotecan by i.v. weekly × 4 schedules...

BACKGROUND: Alopecia is a dermatological disorder with psychosocial implications on patients with hair loss. Hair loss is one of the most feared side effects of chemotherapy. Plants have been widely used for hair growth promotion since ancient times in Ayurveda, Chinese and Unani systems of medicine. The effect of extracts of Cuscuta reflexa Roxb. in testosterone induced alopecia was reported. OBJECTIVE: In the present study, the efficacies of the extracts of Cuscuta reflexa in promoting hair growth in cyclophosphamide-induced hair loss have been determined...

BACKGROUND: Effective, safe and well-tolerated therapeutic and/or preventive regimens for chemotherapy-induced alopecia (CIA) still remain to be developed. Because α-melanocyte-stimulating hormone (α-MSH) exerts a number of cytoprotective effects and is well tolerated, we hypothesized that it may be a candidate CIA-protective agent. OBJECTIVES: To explore, using a human in vitro model for chemotherapy-induced hair follicle (HF) dystrophy that employs the key cyclophosphamide metabolite (4-hydroperoxy-cyclophosphamide, 4-HC), whether α-MSH protects from 4-HC-induced HF dystrophy...

BACKGROUND: Chemotherapy-induced hair loss (alopecia) (CIA) is one of the most feared side effects of chemotherapy among cancer patients. There is currently no pharmacological approach to minimize CIA, although one strategy that has been proposed involves protecting normal cells from chemotherapy by transiently inducing cell cycle arrest. Proof-of-concept for this approach, known as cyclotherapy, has been demonstrated in cell culture settings. METHODS: The eukaryotic initiation factor (eIF) 4E is a cap binding protein that stimulates ribosome recruitment to mRNA templates during the initiation phase of translation...

Alopecia is a psychologically devastating complication of chemotherapy for which there is currently no effective therapy. PTH-CBD is a collagen-targeted parathyroid hormone analog that has shown promise as a therapy for alopecia disorders. This study compared the efficacy of prophylactic versus therapeutic administration of PTH-CBD in chemotherapy-induced alopecia using a mouse model that mimics the cyclic chemotherapy dosing used clinically. C57BL/6J mice were treated with a single subcutaneous injection of PTH-CBD (320 mcg/kg) or vehicle control before or after hair loss developing from three courses of cyclophosphamide chemotherapy (50-150 mg/kg/week)...

Treatment of cancer patients with chemotherapeutics like cyclophosphamide often causes alopecia as a result of premature and aberrant catagen. Because the epidermal growth factor receptor (EGFR) signals anagen hair follicles to enter catagen, we hypothesized that EGFR signaling may be involved in cyclophosphamide-induced alopecia. To test this hypothesis, skin-targeted Egfr mutant mice were generated by crossing floxed Egfr and Keratin 14 promoter-driven Cre recombinase mice. Cyclophosphamide treatment of control mice resulted in alopecia while Egfr mutant skin was resistant to cyclophosphamide-induced alopecia...
