RESUMO

Since the emergence of scalp cooling therapy (SCT) for the prevention of chemotherapy-induced alopecia (CIA), support groups on social media platforms for interested patients have surfaced. Though there are over 20,000 active members across SCT Facebook groups, little is known about how members use this platform. A 23-question survey was posted in five scalp cooling Facebook groups, reaching 219 women. Results indicated that these Facebook groups play clear roles in providing the following: (1) a supportive community for patients, (2) instructions for SCT use, (3) advice regarding insurance coverage and reimbursement, and (4) recommendations for over-the-counter products for hair loss. Despite reported interest in hair loss products, only 5% of patients sought medical treatment from dermatologists. Due to group-specific access restrictions, private Facebook groups provide patients with a protected platform to learn more about SCT from both those with personal experience and SCT company specialists. Providers may consider recommending these online groups to interested patients during the scalp cooling counseling process. As patients with CIA express a growing interest in over-the-counter hair, eyebrow, and eyelash products, it is important for dermatologists to be aware of where their patients obtain recommendations, and further, if these recommendations have clinical evidence of efficacy.

RESUMO

PURPOSE: Automated scalp cooling (ASC) is available to patients undergoing chemotherapy for breast cancer to decrease chemotherapy-induced alopecia. This study sought to elucidate patient and chemotherapy nursing perspectives on the ASC experience. METHODS: This is a survey-based study of chemotherapy nursing staff and patients with breast cancer regarding perceived efficacy, side effects, administration, support, and overall opinions of ASC. Chemotherapy nurses across a large, multi-regional tertiary healthcare system completed a one-time survey regarding their experiences in administering ASC. Breast cancer patients who utilized ASC were surveyed along with a control group who underwent alopecia-inducing chemotherapy without ASC use for comparison. RESULTS: The majority of nursing responses reported inadequate technical support, an increased burden of administering ASC compared to other clinical duties, and that they would not recommend ASC to a family member or friend. Patients who underwent ASC reported significantly less hair loss and were significantly less likely to shave their heads or wear a wig, but this did not translate into significant differences in body image or psychosocial wellbeing responses. Time investment was the most significant burden related to ASC. CONCLUSION: Patients using ASC reported significantly less hair loss compared to those not using ASC during alopecia-inducing breast cancer chemotherapy, but this did not translate to improved body image. The majority of chemotherapy nurses reported they lacked adequate support in administering ASC and would not recommend it. Enhanced nursing support may provide a means for improving the ASC experience for both nursing staff and patients.

RESUMO

PURPOSE: Alopecia is a common side-effect of chemotherapy and can be extremely distressing to patients. Scalp cooling can be used to reduce hair loss, but the optimal duration of cooling remains unclear. Our aim was to determine whether increasing the duration of scalp cooling improves hair preservation. METHODS: Patients with HER2-negative, non-metastatic, breast cancer received scalp cooling during adjuvant chemotherapy: three cycles of epirubicin/cyclophosphamide (EC) followed by three cycles of paclitaxel. The patients were randomly assigned to two groups. Group A (n=18) wore a Paxman cooling cap during each infusion and for 30 min post-infusion while Group B (n=19) wore the cap from 30 min before to 2 h after each infusion. All patients were asked to complete a questionnaire recording hair loss/regrowth, adverse events, and quality of life. Success of treatment was defined as <50% hair loss. RESULTS: The success rates after each of the three cycles did not differ significantly between the two groups (EC: Group A: 40%, Group B: 44%; paclitaxel: Group A: 50%, Group B: 36%; p>0.05). Hair regrowth was significantly higher in Group B at the 8-week follow-up, but not at the 6-month follow-up. Head discomfort affected more patients in Group B than in Group A during the first session (94% vs. 62%, respectively; p=0.039). CONCLUSION: Long duration scalp cooling during chemotherapy might increase patients' discomfort and does not appear to improve hair preservation.

RESUMO

This narrative review aims to examine the therapeutic potential and mechanism of action of plant extracts in preventing and treating alopecia (baldness). We searched and selected research papers on plant extracts related to hair loss, hair growth, or hair regrowth, and comprehensively compared the therapeutic efficacies, phytochemical components, and modulatory targets of plant extracts. These studies showed that various plant extracts increased the survival and proliferation of dermal papilla cells in vitro, enhanced cell proliferation and hair growth in hair follicles ex vivo, and promoted hair growth or regrowth in animal models in vivo. The hair growth-promoting efficacy of several plant extracts was verified in clinical trials. Some phenolic compounds, terpenes and terpenoids, sulfur-containing compounds, and fatty acids were identified as active compounds contained in plant extracts. The pharmacological effects of plant extracts and their active compounds were associated with the promotion of cell survival, cell proliferation, or cell cycle progression, and the upregulation of several growth factors, such as IGF-1, VEGF, HGF, and KGF (FGF-7), leading to the induction and extension of the anagen phase in the hair cycle. Those effects were also associated with the alleviation of oxidative stress, inflammatory response, cellular senescence, or apoptosis, and the downregulation of male hormones and their receptors, preventing the entry into the telogen phase in the hair cycle. Several active plant extracts and phytochemicals stimulated the signaling pathways mediated by protein kinase B (PKB, also called AKT), extracellular signal-regulated kinases (ERK), Wingless and Int-1 (WNT), or sonic hedgehog (SHH), while suppressing other cell signaling pathways mediated by transforming growth factor (TGF)-ß or bone morphogenetic protein (BMP). Thus, well-selected plant extracts and their active compounds can have beneficial effects on hair health. It is proposed that the discovery of phytochemicals targeting the aforementioned cellular events and cell signaling pathways will facilitate the development of new targeted therapies for alopecia.

RESUMO

OBJECTIVE: Chemotherapy induced alopecia (CIA) is one of the most common side effects in cancer patients, however; it doesn't have an effective pharmacological treatment yet. In this study we aimed to research the protective effect of newly developed HDDPiW-jSB solution on docetaxel (DTX) -induced rat alopecia model. MATERIAL AND METHODS: Docetaxel (10 mg/kg/week) was administered to the 6-8 months old rats for three weeks. HDDPiW-jSB solution was applied once or twice a week for 4 weeks beginning prior to one week before DTX. Rat hair follicles were evaluated with hematoxylin-eosin and immune-histochemical staining. RESULTS: In the first stage of this study, alopecia was successfully developed by DTX (10 mg/kg/three times) application. In the second stage of the study, application of HDDPiW-jSB solution, did not change the study parameters significantly on control group. The solution improved the anagen hair follicle count and Bcl-2 levels in the skin samples of DTX-induced alopecic rat groups, especially when applied twice weekly. Additionally, level of Caspase 3 was decreased. HDDPiW-jSB solution was safe when applied on the skin. CONCLUSION: Topical HDDPiW-jSB solution could be effective and safe for the protection of DTX-induced alopecia in rat models.

RESUMO

The plant Justicia procumbens is traditionally used in Asia to treat fever, cough, and pain. Previous studies have reported its anticancer and anti-asthmatic properties. However, its potential for preventing androgenic alopecia (AGA) has not yet been reported. AGA is a widespread hair loss condition primarily caused by male hormones. In this study, we examined the hair loss-preventing effects of an aqueous extract of J. procumbens (JPAE) using human hair follicle dermal papilla cell (HFDPC) and a mouse model of testosterone-induced AGA. JPAE treatment increased HFDPC proliferation by activating the Wnt/ß-catenin signaling pathway. Additionally, JPAE increased the expression of Wnt targets, such as cyclin D1 and VEGF, by promoting the translocation of ß-catenin to the nucleus. Administration of JPAE reduced hair loss, increased hair thickness, and enhanced hair shine in an AGA mouse model. Furthermore, it increased the expression of p-GSK-3ß and ß-catenin in the dorsal skin of the mice. These findings imply that JPAE promotes the proliferation of HFDPC and prevents hair loss in an AGA mouse model. JPAE can therefore be used as a functional food and natural treatment option for AGA to prevent hair loss.

RESUMO

BACKGROUND: The incidence and severity of alopecia vary mainly depending on the chemotherapeutic agent used or other drug groups. The pathogenetic characteristics of the different forms of alopecia are reflected in the clinical presentation and, in some cases, in the resulting recommendations for prophylaxis. OBJECTIVES: To provide an overview of the pathogenesis, clinical presentation, diagnosis and prophylaxis of alopecia with chemotherapeutic agents, hedgehog inhibitors, targeted therapies and immune checkpoint inhibitors. MATERIALS AND METHODS: Based on the current S3 guideline "Supportive therapy", an extensive literature search was carried out. RESULTS AND CONCLUSION: Chemotherapy-induced hair loss (CIA) occurs in up to 65% of cases. Anagen effluvium is observed as early as 1-3 weeks after the start of treatment and is reversible in most cases. Alopecia associated with inhibitors of the Sonic Hedgehog signaling pathway (HHIA) such as vismodegib or sonidegib are observed in up to 60% of cases. They are characterized by telogen effluvium. BRAF or immune checkpoint inhibitors lead significantly less frequently to alopecia (BRAFA, CPIA). According to taxane-based chemotherapy protocols, scalp cooling can help to prevent higher-grade CIA. If CIA or other forms of alopecia are expected, early contact with self-help organizations and early prescriptions for wigs should be offered.

RESUMO

Uno de los efectos adversos que generan mayor impacto psicosocial en los pacientes que se someten a quimioterapia es la pérdida de cabello. El uso de los cascos fríos podría representar una alternativa para prevenir la alopecia. Estos dispositivos producen vasoconstricción en los vasos sanguíneos del cuero cabelludo provocando que los quimioterápicos lleguen en menores concentraciones a los folículos pilosos, y por consiguiente, evitando que los citotóxicos alcancen el metabolismo de las células foliculares. Se propone que este proceso permita prevenir la alopecia, aunque existe una preocupación que es la posibilidad de metástasis en cuero cabelludo si la quimioterapia no llega a este tejido. Partiendo de la consulta de una paciente con diagnóstico reciente de cáncer de mama, surge el interrogante si en pacientes en tratamiento con quimioterapia el uso de cascos fríos en comparación con su no utilización, disminuye la caída del cabello y si aumenta el riesgo de metástasis en cuero cabelludo. Luego de realizar una búsqueda, se analizaron los resultados de tres artículos pertinentes. Se concluye que el uso de cascos fríos en pacientes que reciben quimioterapia representaría una opción válida para prevenir la alopecia sin indicios de problemas de seguridad y se realiza una reseña acerca de la disponibilidad de los cascos fríos en Argentina.

One of the adverse effects that generate greater psychosocial impact in patients undergoing chemotherapy is hair loss. The use of cold caps could represent an alternative to prevent alopecia. These devices produce vasoconstriction in the blood vessels of the scalp, causing chemotherapeutic agents to reach the hair follicles in lower concentrations, and there forepreventing toxins from being metabolized by the follicular cells. Thus, alopecia could be prevented but, there is a concern that is the possibility of metastasis to the scalp if the therapy does not reach this tissue. Based on a consultation of a patient recently diagnosed with breast cancer, the question arises whether in patients undergoing chemotherapy the useof cold caps compared to their non-use reduces hair loss and whether it in creases the risk of metastasis to the scalp. After performing a search, the results of three relevant articles were analyzed. It is concluded that the use of cold helmets in patients receiving chemotherapy would represent a valid option to prevent alopecia without indications of safety problems. Finally, a review is made about the availability of scalp-cooling devices in Argentina.
