Review Article a Multidisciplinary Evaluation for Advanced Supportive Care of Breast Cancer Patients.

Background: Cancer cases diagnosed each year are increasing, mainly because the population is ageing and, in part, due to early detection. This implies that there are more and more persons that receive medical anticancer therapies and that are interested in maintaining their quality of life. Many oncological treatments, including chemotherapy, immunotherapy, surgery, and radiotherapy, and combined therapy are associated with cutaneous toxicity and long-term side effects to different tissues and organs. This is particularly relevant when new therapies are used since these may cause new and unexpected side effects that may be short-lived but, in some cases, may become chronic or permanent. Patients often seek advice with their oncologists on what can be done and what cannot be done. Notably, many of the cutaneous side effects can be prevented or reduced by adequate interventions. Summary: The aim of this review is to highlight how oncological patients may benefit from a closer collaboration between specialists in different branches. We will focus on women with breast cancer since we think that they may derive a special benefit from this collaboration, but we will analyse other cancers in future papers. Key Messages: The working group was created to help the medical doctor in the prevention and management of all the adverse effects of the oncological treatments, supporting patients in this phase of their life, including nutritional assessment and dietary support.

Detection of novel therapies using a multi-national, multi-institutional registry of cutaneous immune-related adverse events and management.

BACKGROUND: Cutaneous immune-related adverse events (cirAEs) remain a prevalent and common sequelae of immune checkpoint inhibitor (ICI) therapy, often necessitating treatment interruption and prolonged immune suppression. Treatment algorithms are still poorly defined, based on single-institution case reports without adequate safety assessments, and subject to publication bias. METHODS: Data in this registry were collected through a standardized REDCap form distributed to dermatologists via email listserv. RESULTS: Ninety-seven cirAEs were reported from 13 institutions in this registry. Topical and systemic steroids were the most common treatments used; however, targeted treatment matched to disease morphology was identified at numerous sites. Novel cirAE therapy uses that to our knowledge have not been previously described were captured including tacrolimus for the treatment of follicular, bullous, and eczematous eruptions and phototherapy for eczematous eruptions. Moreover, further evidence of cirAE treatment applications sparsely described in literature were also captured in this study including dupilumab and rituximab for bullous eruptions, phototherapy for lichenoid and psoriasiform eruptions, and acitretin for psoriasiform eruptions, among others. No serious adverse events were reported. Numerous targeted therapeutics including dupilumab, rituximab, and psoriasis biologics, among others, were associated with a cirAE grade improvement of ≥2 grades in every patient treated. CONCLUSION: This study suggests that a multi-institutional registry of cirAEs and management is not only feasible but that the information collected can be used to detect, evaluate, and rigorously assess targeted treatments for cirAEs. Further expansion and modification to include treatment progression may allow for sufficient data for specific treatment recommendations to be made.

Clinical and Trichoscopic Graded Live Visual Scale for Androgenetic Alopecia.

Introduction: Currently, the mostly used classifications of androgenetic alopecia (AGA) only provide a macroscopic and subjective description of this disorder, without evaluating trichoscopic features. Objectives: The aim of this study is to elaborate a graded live visual AGA severity scale including macroscopic and microscopic (trichoscopic) pictures, and to determine the most frequent trichoscopic characteristics associated to each grade. Methods: A retrospective observational study was conducted on 122 patients (50 females and 72 males) affected by AGA. Macroscopic and trichoscopic photographs were taken at standardized scalp points. Results: Each picture was ranked from AGA stage I to VII, according to Hamilton scale for men and Sinclair scale for women, and the most representative images of each severity degree were collected to produce a graded live visual scale. In males, 2 live visual scales, 1 for the anterior and 1 for posterior region of the scalp were created. In females, only 1 scale of the anterior region was realized. For each stage of severity, the corresponding trichoscopic parameters were statistically analyzed. Conclusions: We realized new macroscopic and trichoscopic graded live visual scales for male and female patients affected by AGA, which could help physicians in giving an objective evaluation of the disease and in better managing it.

Recommendations on trichological treatments during COVID-19 pandemic.

COVID-19 is an infectious disease caused by the novel coronavirus SARS-CoV-2, which rapidly spreads via respiratory droplets and is the cause of the current pandemic. In this alarming situation, it is a delicate matter how to visit patients safely and how to manage their chronic treatments. The aim of this paper is to examine in detail the potential impact on SARS-CoV-2 infection of treatments routinely used in trichology and to provide a useful guide for the therapeutic management of trichological patients in this new COVID-19 era.

Recurrence of alopecia areata after covid-19 vaccination: A report of three cases in Italy.

BACKGROUND: Common COVID-19 vaccines side effects are pain at the injection site, muscle pain, fever, headaches, fatigue. Possible immune-related side effects in predisposed individuals have not been established so far. MATERIALS AND METHODS: We report three cases of recurrence of alopecia areata (AA) occurred after the first dose of COVID-19 vaccine. RESULTS: All patients had previous episodes of AA with total hair regrowth and stable remission during the months preceding the vaccination. Rapid hair loss occurred 2-3 weeks after BNT162b2 mRNA (patient 1) and AZD1222/ChAdOx1 vaccine (patient 2 and 3), with widespread hair loss in two cases and a single patch of the vertex in one case, with typical trichoscopic features of AA. DISCUSSION: Both BNT162b2 mRNA and AZD1222/ChAdOx1 vaccines share the same goal of inducing the immune system, with antibodies production and Th1 cells activation with release of pro-inflammatory cytokines. Thus, in patients with pre-existing inflammatory dysregulated pathways, the interaction between the immune system and vaccines may enhance other autoimmune mechanisms. In our cases, we speculate that vaccine may have induced the hair loss focusing on components having a key role in both COVID-19 vaccination and AA pathogenesis. CONCLUSION: This report may help to collect new data concerning possible immune-related effects of vaccines. Certainly, only three cases are not sufficient to draw conclusion, thus a large-scale study is necessary. Immune-mediated side effects remain a rare event, thus the benefits of COVID-19 vaccines outweigh the risk of disease flares and we strongly recommend it in all eligible patients with AA.

Are dissecting cellulitis and hidradenitis suppurativa different diseases?

Although dissecting cellulitis (DC) and hidradenitis suppurativa (HS) are classified separately, they share many clinical, dermatoscopic, pathogenetic, and histologic aspects, as well as therapeutic options. The association between DC, HS, and acne conglobata represents the follicular occlusion triad or follicular occlusion tetrad, which may include a pilonidal sinus. DC, also known as "folliculitis et perifolliculitis capitis abscendes et suffoidens," is classified as a secondary cicatricial and neutrophilic alopecia. It occurs with perifolliculitis of the scalp, dermal abscesses, sinus tract development, and secondary scarring alopecia. HS, sometimes known as acne inversa, is a chronic relapsing inflammatory disease afflicting apocrine gland-rich areas of the body with painful nodules and abscesses, sinus tracts, and scarring. Given the overlap between the clinical features and the pathogenesis of DC and HS, it would be more appropriate to consider these conditions as two different localizations of the same disease rather than two different pathologies, being a follicular occlusion disease occurring on the scalp and on the apocrine gland-rich areas of the body.

Clinical aspect, pathogenesis and therapy options of alopecia induced by hormonal therapy for breast cancer.

Adjuvant hormonal therapy is one of the most important treatments of hormone-receptor-positive breast cancer and includes selective estrogen receptor modulators, aromatase inhibitors, and luteinizing hormone-releasing hormone analogs. In patients receiving these drugs, a progressive recession of frontal-temporal hairlines is often observed, such as a certain grade of hair miniaturization in the same areas and the central scalp area, producing a pseudo-female androgenic alopecia, which has to be considered oncotherapy-induced alopecia. The aim of this work, is to describe the clinical aspects and pathogenesis of this type of alopecia and to analyze the different drugs which have been proposed until now. The authors concude that topical hormones should not be considered as a therapeutic approach because of their direct or indirect oncogenic potential. A therapeutic approach that could be both safe and effective is proposed.

A new treatment of alopecia induced by palbociclib: Topical cetirizine.

INTRODUCTION: Recently CDK4/6 inhibitors have been introduced for the treatment of hormone positive breast cancer resistant to endocrine therapy. Among their side effects, alopecia is often reported being associated to patients' distress and depressive symptoms. CASE REPORT: We report the case of a 70-year-old woman affected by breast cancer in treatment with Palbociclib, who developed alopecia.Management and Outcome: We prescribed a topical solution with cetirizine. Global photography, trichoscopy and trichogram were assessed. All evaluations demonstrated alopecia improvement. DISCUSSION: Currently, no treatment options for CDK 4/6 inhibitors induced alopecia have been proposed. Herein, we report the use of topical cetirizine.

Capillaroscopy: a new application for the evaluation of vascular side-effects induced by chemotherapy.

BACKGROUND: Cancer survivors are rising up, but this better survival is accompanied by possible treatments side-effects. In particular, cardiovascular effects are commonly reported, even if vascular damage is not necessarily connected to clinical manifestations. Periungual microcircle evaluation through capillaroscopy could identify asymptomatic patients with high risk of cerebro-cardio-vascular disease. The aim of this pivotal study was to evaluate videocapillaroscopy in patients who undergo chemotherapy, in order to understand if it could represent in future a prognostic tool to predict the risk of cardio-cerebro-vascular events. METHODS: We conducted an open-label, uncontrolled study. Patients affected by solid tumors were enrolled. Each subject underwent a clinical evaluation and a videocapillaroscopic examination. RESULTS: We selected 25 patients. Mean age was 55.48 years. Time interval between the start of chemotherapy and capillaroscopy: average 41 months. From our analysis it emerges that ectasia and hemorrhages could be a possible marker of capillary insult caused by chemotherapy. CONCLUSIONS: Our study showed the presence of capillaroscopic features that may be peculiar in chemotherapy-induced endothelial damage. The individuation of capillaroscopic alteration specific for chemotherapy-induced endothelial injury could be an important tool to identify patients with high cardiovascular risk.

Dermatologic management of oncotherapy side effects: A proposed algorithm.

Since the introduction of the first chemotherapeutic regimens for the treatment of oncological disease, hundreds of drugs have been approved for cancer treatment and many more are under investigation. The development of newer drugs such as target therapies, immuno-oncotherapies, and hormonal therapies has increased in specificity with the development of smaller molecules and more selective targets. Cutaneous side effects are now well known for both standard chemotherapy and targeted therapies. The correct diagnosis and management of these effects are of vital importance both to optimize therapeutic success rates and to reduce the patient's suffering. In fact, the appearance of a cutaneous adverse event can be responsible for a reduction in drug dosage or worse its suspension. In order to achieve this objective, we propose a management algorithm, based on three different steps, before, during, and after the oncological treatments, respectively. Our proposal underlines the importance of correct skin care measures to limit or reduce the severity of side effects.

Frontal fibrosing alopecia and genital Lichen sclerosus: Single-center experience.

BACKGROUND: Despite the incidence of Frontal fibrosing alopecia (FFA) has been increasing in last two decades, the pathophysiology and trigger factors of FFA have not been yet fully understood. AIMS: The aim of this study was to describe epidemiology, clinical and trichoscopic features and comorbidities of FFA patients, in order to improve the understanding of this disease. PATIENTS/METHODS: A retrospective, observational monocentric study was conducted from 2003 to 2019. Data concerning epidemiology (age, gender, age of menopause, and age of FFA onset), comorbidities, current therapies, localization of FFA (such as frontotemporal hairline, occipital, eyebrow, eyelash, beard, sideburns, and body hair), presence of papules and sign of Lichen planus (LP) at skin, mucosae and/or nail were collected for each patient included. RESULTS: A total of 119 Caucasian, adult patients (8 men and 111 female) with FFA were enrolled in the study. Cutaneous, mucosal, or nail localization of LP were found in 16% of our subjects. Interestingly, 15 out of 119 subjects (10.61%) were affected by concomitant genital Lichen sclerosus (LS) and 5 out of these 15 patients (4.38%) presented both LS and LP in association with FFA. CONCLUSION: Considering the high prevalence of LS in FFA patients in our case series, and the frequency of autoimmune comorbidities in both LS and FFA, it is possible to hypothesize an autoimmune process in both conditions. Further studies are needed for a better understanding of the nature of the association between LS and FFA.

Prevention and Treatment of Chemotherapy-Induced Alopecia.

BACKGROUND: Chemotherapy-induced alopecia (CIA) is one of the most dramatic side effects of chemotherapy. Currently no guidelines are available for its prevention and treatment. Several devices and drugs are used, but results are often disappointing. AIMS: Our aim is to analyze drugs and devices proposed in the literature for prevention and treatment of CIA induced by cytotoxic drugs and to discuss the evidenced-based opinion. METHODS AND RESULTS: Scalp cooling is the only agent that has been approved by the US Food and Drug Administration for CIA prevention. Minoxidil and bimatoprost should not be used during chemotherapy administration, but they can be used after chemotherapy discontinuation to obtain greater regrowth. CONCLUSIONS: Therapy should always be modulated for the patient and no fixed protocol should be used. Trichoscopy and trichogram could be useful tools in supporting this treatment.

Efficacy of Topical Finasteride 0.5% vs 17α-Estradiol 0.05% in the Treatment of Postmenopausal Female Pattern Hair Loss: A Retrospective, Single-Blind Study of 119 Patients.

BACKGROUND AND OBJECTIVES: Female pattern hair loss (FPHL) is a common form of scalp hair loss that occurs in 38% of females. Currently, minoxidil solution is the only therapy approved by the US Food and Drug Administration, but many other treatments are used, including cyproterone acetate, spironolactone, topical 17α-estradiol, and prostaglandin analogs. Systemic finasteride has been considered a treatment option in women even though its teratogenic effects tend to limit its prescription. Recently, topical finasteride has been evaluated to limit the side effect profile of the drug. The objective of the present study is to compare retrospectively the efficacy of topical 0.05% 17α-estradiol solution and a 0.5% finasteride lotion in the treatment of FPHL. PATIENTS AND METHODS: We enrolled 119 postmenopausal female patients. The first group comprised 69 women treated with finasteride 0.5% and minoxidil 2%. The second group included 50 women treated with 17α-estradiol 0.05% and minoxidil 2%. At baseline and at 6- and 12- to 18-month follow-up, global photographs were systematically taken. Three operators blind to the prescribed treatment evaluated photographs using a 7-point scale. One-way analysis of variance and unpaired Student t tests were performed to analyze 7-point scale scores. RESULTS: The improvement was statistically significant from 6 months to 12-18 months, both for finasteride (P < 0.005) and 17α-estradiol (P < 0.05). The efficacy of topical finasteride was significantly greater than that of 17α-estradiol solution, both at the 6-month (P < 0.05) and at the 12- to 18-month follow-up (P < 0.005). In general, the highest improvement was observed after 12-18 months of treatment with topical finasteride therapy. CONCLUSIONS: Topical finasteride 0.5% in combination with minoxidil 2% could represent a valid therapeutic option for the treatment of postmenopausal FPHL, showing higher efficacy than topical 17α-estradiol with minoxidil 2% both at 6-month and 12- to 18-month follow-up.

Eosinophilic folliculitis of the scalp associated with PD-1/PDL1 inhibitors.

BACKGROUND: Immune checkpoint inhibitors are monoclonal antibodies which target immune "checkpoints" enhancing T cell-mediated cytotoxic and antitumor responses. Together to the amazing results, these drugs are associated with some peculiar adverse events called immune-related adverse events. Alopecia is one of these. It is usually reported to be clinically and histologically similar to alopecia areata. AIMS: We report a case of eosinophilic folliculitis of the scalp occurred during nivolumab therapy, its management and some pathogenetic hypotheses. PATIENT: Herein, we report the first case of eosinophilic folliculitis of the scalp occurred during nivolumab therapy, firstly appeared as a lichen planopilaris. Topical steroids and fusidic acid cream were applied with partial benefit and a scaring outcome. No discontinuation of nivolumab was required. CONCLUSION: Immune checkpoint inhibitors induced inflammatory response leads to the exposure of hair follicle antigens and a consequent loss of Immuno Privilege. We hypothesize a role of steroids in deviating a primarily lichenoid reaction toward a folliculitis.

Isoradiotopic response of discoid lupus after radiotherapy: A case report and review of the literature.

Radiotherapy is frequently associated with a great number of collateral effects, which can affect the skin and its appendages. In addition to more common side effects, like radiodermatitis, other cutaneous conditions are less known and often they are underdiagnosed. Among these, isoradiotopic response is one of the rare radiotherapy-associated phenomena. This term refers to the appearance of a secondary dermatosis in a previously irradiated district. The term was used for the first time by Shurman et al. to describe a case of lichen ruber planus arising in the genital area after radiotherapy for squamous cell carcinoma. The pathologic mechanism is not completely clear, but a few hypotheses have been proposed. Alterations in the local lymphatic drainage, in the nervous system and the immune microenvironment have all been called into play (the immunocompromised district theory). We present the case of a male patient that developed discoid lupus on a previously irradiated cutaneous area and review the literature, highlighting the numerous possible manifestations of this phenomenon.

Italian Guidelines in diagnosis and treatment of alopecia areata.

Alopecia areata (AA) is an organ-specific autoimmune disorder that targets anagen phase hair follicles. The course is unpredictable and current available treatments have variable efficacy. Nowadays, there is relatively little evidence on treatment of AA from well-designed clinical trials. Moreover, none of the treatments or devices commonly used to treat AA are specifically approved by the Food and Drug Administration. The Italian Study Group for Cutaneous Annexial Disease of the Italian Society of dermatology proposes these Italian guidelines for diagnosis and treatment of Alopecia Areata deeming useful for the daily management of the disease. This article summarizes evidence-based treatment associated with expert-based recommendations.
