Electrochemotherapy for Breast Cancer-Results From the INSPECT Database.

BACKGROUND: Cutaneous recurrence from breast cancer can pose a clinical challenge. It might be the only disease site, or could be part of disseminated disease, and often profoundly affects quality of life. Electrochemotherapy is a palliative treatment using electric pulses to locally permeabilize tumor cells and thereby significantly increase bleomycin cytotoxicity. Collaborating with the International Network for Sharing Practice on ElectroChemoTherapy (INSPECT), we consecutively and prospectively accrued data on patients treated with electrochemotherapy for cutaneous metastases from breast cancer. PATIENTS AND METHODS: Patients were treated with electrochemotherapy at 10 European centers. Under either local or general anaesthesia patients were treated with either local injection (1000 IU/mL intratumoral) or systemic infusion (15,000 IU/m2) of bleomycin. RESULTS: One hundred nineteen patients were included at 10 institutions in the INSPECT network. The primary location was the chest (89%), the median diameter of the cutaneous metastases was 25 mm. Ninety patients were available for response evaluation after 2 months. Complete response was observed in 45 patients (50%), partial response in 19 (21%), stable disease in 16 (18%), and progressive disease in 7 (8%). Three patients were not evaluable. Common side effects were ulceration, long-lasting hyperpigmentation, and low-grade pain. No serious adverse events were observed. CONCLUSION: Electrochemotherapy showed high response rates after a single treatment. Electrochemotherapy has few side effects and can be used as an adjunct to systemic therapies or as a solo treatment. We therefore recommend considering electrochemotherapy for patients with cutaneous metastases.

Frontal Fibrosing Alopecia: A Retrospective Analysis of 72 Patients from a German Academic Center.

Frontal fibrosing alopecia (FFA) describes the scarring, band-like recession of the frontotemporal hairline. Treatment is difficult, and currently, no evidence-based therapy exists. The purpose of this study is to report clinical features and treatment responses in a large cohort of patients with FFA. The authors analyzed a series of 72 patients with a clinical or histologic diagnosis of FFA. A total of 70 patients were female (97.2%), and 2 were male (2.8%). In females, the first onset of FFA was postmenopausal in 81.4% (n = 57). Documented eyebrow loss was present in 61.1% (n = 44), whereas involvement of eyelashes and body hair was reported in only 4.2% (n = 3) and 5.6% (n = 4), respectively. Clinical symptoms were itching (40.3%, n = 29) and trichodynia (4.2%, n = 3) in the alopecic area. Virtually all patients were treated with topical high-potency steroids. Additional treatments were topical tacrolimus, systemic retinoids, and hydroxychloroquine. A total of 48 patients (66.7%) received a combination of high-potency steroids with topical pimecrolimus. In this subgroup, subjective improvement or disease stabilization was reported by 64.6% (n = 31), and the hairline was stabilized on average after 9 to 12 months of therapy. The combination therapy of topical high-potency steroids with pimecrolimus may be an effective and steroid-saving treatment for FFA.

"Twin lesions": Which one is the bad one? Improvement of clinical diagnosis with reflectance confocal microscopy.

BACKGROUND: In vivo reflectance confocal microscopy (RCM) is a novel non-invasive diagnostic tool, which is used to differentiate skin lesions. Even in lesions with similar dermatoscopic images, RCM may improve diagnostic accuracy. METHODS: Three sets of false "twin lesions" with similar macroscopic and dermatoscopic images are matched. All lesions are evaluated with RCM and lesions are excised for further evaluation. Corresponding features in confocal images, dermatoscopy and histopathology are discussed. RESULTS: In all matched pairs, one of the lesions was diagnosed as melanoma with the observation of melanoma findings such as: epidermal disarray, pagetoid cells in epidermis and cellular atypia at the junction. Benign lesions were differentiated easily with RCM imaging. CONCLUSION: Examining dermatoscopically difficult and/or similar lesions with RCM facilitates diagnostic and therapeutic decision making. Using RCM in daily practice may contribute to a decrease in unnecessary excisions.

Periocular discoloration after using a prostaglandin analog for eyelash enhancement: evaluation with reflectance confocal microscopy.

A 32-year-old Caucasian woman was admitted to our outpatient department with periocular discoloration. She applied a serum with the active ingredient isopropyl cloprostenate for enhancing the growth of the eyelashes. The discoloration appeared for the first time when the patient had used the serum and gradually remitted after the discontinuation of use. Confocal laser scanning microscopy revealed small white spots in the perifollicular dermis and in the surrounding dilated vessels, which was reported earlier as a side effect of prostaglandin analogs.

Predicting patients at risk for pain associated with electrochemotherapy.

BACKGROUND: Electrochemotherapy describes the use of electric pulses to enhance chemotherapy uptake, and has proven highly efficient in treating cutaneous metastases. Patients referred for electrochemotherapy present with diverse clinical pictures, from multiple small lesions to large, ulcerated lesions. Post-electrochemotherapy pain has been observed in some patients. The objectives of this study were to evaluate pain scores before and after electrochemotherapy, and to investigate if patients at risk of post-procedure pain could be identified. METHODS: Seven cancer centres in the International Network for Sharing Practices on Electrochemotherapy (INSPECT) consecutively and prospectively reported to a common database. Electrochemotherapy consisted of intratumoural or intravenous injection of bleomycin, followed by delivery of electric pulses in local or general anesthesia. RESULTS: Of 121 patients 39% had metastatic melanoma, 18% squamous cell carcinoma, 16% breast cancer, 13% basal-cell carcinoma, and 14% other malignancies. Median size of the largest nodules was 2.3 cm (range 0.3-40 cm). A majority of patients presented with low pain scores, and this continued through follow-up (74%). A subset of patients had moderate (13%) or severe pain (13%) after treatment. Post-procedure pain was statistically significantly associated with: 1) moderate or severe pain before treatment (p<0.0001); 2) size of the largest treated lesion (p<0.01); 3) previous irradiation (p<0.02); and 4) high treatment current value (p<0.0001). CONCLUSION: The majority of patients had no or mild pain after electrochemotherapy. Patients at risk for post-procedure pain could be identified at the pre-treatment visit, and/or at the time of treatment, enabling a pain management strategy for this group.

Chronic hand eczema: perception and knowledge in non-affected individuals from general and dermatological practice.

Misunderstanding and stigmatisation are common problems encountered by patients with hand eczema. Various misconceptions about the disease circulate in the general population. Although hand eczema has gained more attention in dermatology during the past years, information on public perception of the disease is still lacking. The aim of our study was to investigate perception of and level of knowledge on the subject hand eczema. There were 624 patients included from 2 general medicine practices and 2 dermatological practices. A self-administered questionnaire was filled out by the participants, covering issues on history of hand eczema, level of knowledge and attitude towards a clinical photograph of hand eczema. We found that a larger proportion of individuals from dermatological practice were more familiar with hand eczema as a disease than those from general medical practice. Women knew significantly more about and had a more positive perception of the disease than men. Our results imply that the level of knowledge on hand eczema in the general public is rather low and influenced by prejudice.
