Abstract
We hypothesise that regression may have an impact on the effectiveness of adjuvant IFN therapy, based on its role in the host immune response. Our purpose is to investigate regression and ulceration as prognostic factors in case of interferon-alpha (IFN)-treated melanoma patients. We followed 357 IFN-treated melanoma patients retrospectively, investigating progression-free survival (PFS) and overall survival (OS) depending on the presence of ulceration and regression. A Kaplan-Meier analysis was performed, and we used a Cox regression analysis to relate risk factors. The survival function of the Cox regression was used to measure the effect of regression and ulceration on PFS and OS depending on the Breslow thickness (T1-T4) of the primary tumour. Regression was significantly positively related to PFS ( P = 0.0018, HR = 0.352) and OS ( P = 0.0112, HR = 0.380), while ulceration showed a negative effect (PFS: P = 0.0001, HR = 2.629; OS: P = 0.0003, HR = 2.388). They influence survival independently. The most favourable outcome was measured in the regressed/non-ulcerated group, whereas the worse was in the non-regressed/ulcerated one. Of risk factors, Breslow thickness is the most significant predictor. The efficacy of regression is regardless of Breslow thickness, though the more favourable the impact of regression was in the thicker primary lesions. Our results indicate that regression is associated with a more favourable outcome for IFN-treated melanoma patients, whereas ulceration shows an inverse relation. Further studies are needed to analyse the survival benefit of regression in relation to innovative immune checkpoint inhibitors.

Abstract
BACKGROUND/AIM Targeted therapy and immunotherapy, with additional stereotactic radiation therapy (SRT) have revolutionized the management of metastatic malignant melanoma (mMM). We aimed to analyze the effectiveness and safety of SRT and determine its role in the complex management of mMM. PATIENTS AND METHODS We treated 24 patients with solitary metastasis, 15 with oligometastatic disease and one with multiple metastases. The primary endpoint was to investigate the possible effect of stereotactic radiotherapy for metastatic lesions on patients' survival taking the systemic therapy into consideration. RESULTS The median overall survival (OS) for the entire group was 30.07 months; 50% of them received immunotherapy, 32% received targeted therapy. Complete remission of the irradiated lesions was observed in six patients, partial tumor response was achieved in 13, while stable disease was detected in 10; tumor progression occurred in four cases. Compartmental recurrence (recurrence in the brain in a not previously irradiated region) developed in seven patients. OS was significantly longer in those with extracranial metastases treated with stereotactic body radiotherapy in comparison to brain SRT. We found a strong correlation between tumor response and mean OS (42.5 months after complete or partial remission versus 11.8 months in those with stable or progressive disease). No OS difference was observed according to the number of irradiated lesions or type of systemic therapy before SRT (no therapy: 43.6 months, with therapy: 25.7 months). Significant OS advantage was shown when immunotherapy was administered post-SRT (mean OS: with immunotherapy: 39.6 months, no immunotherapy: 18.5 months). CONCLUSION In the case of oligometastatic MM, SRT can be used safely and with good efficiency in addition to targeted therapy/anti-programmed cell death protein 1 therapy. Improved survival warrants including SRT in the complex management of mMM, however, further studies are needed for SRT optimization.

Abstract
INTRODUCTION The risk of cutaneous malignancies is significantly higher in immunosuppressed patients compared to the general population. These high-risk skin tumors tend to be aggressive, multiplex, rapidly growing lesions. It is common to see local recurrence after surgical excision. Multiplex tumors are difficult to treat, especially in the head/neck region. OBJECTIVE Amongst the standard treatment options, electrochemotherapy can be a suitable option. Our aim was to evaluate the efficacy of electrochemotherapy in immunocompromised patients. METHOD In 9 immunosuppressed patients, 118 (average: 13, n = 5-27) non-melanoma skin tumors were treated with electrochemotherapy with intravenous administration of bleomycin, according to the ESOPE criteria. RESULTS The median follow-up was 15 months. 6 months after the treatment, the objective response rate was 96%. We observed complete response in 88%, partial response in 8% and progressive disease in 2% of the treated lesions. In 2%, the response was not evaluable. CONCLUSION In immunocompromised patients, electrochemotherapy is an effective and safe therapeutic option for non-melanoma skin tumors. In order to provide more ideal management for this special sub-group, prevention, multidisciplinary approach and optimized immunosuppressive therapy is essential. Orv Hetil. 2023; 164(37): 1462-1468.

Abstract
Bevezetés: A fotodinámiás terápia a superficialis basalsejtes
carcinoma, a Bowen-kór és az aktinikus keratosis kezelésére alkalmas eljárás. A
módszer lényege, hogy a kezelendő bőrfelületre felvitt fényérzékenyítő anyag
metabolitjából fény hatására reaktívoxigén-gyökök szabadulnak fel, melyek
szelektíven a tumorsejtek pusztulásához vezetnek. Az eljárás mesterséges
fényforrással vagy a napfény alkalmazásával végezhető. Ez utóbbi a „daylight”
fotodinámiás terápia, melynek hatékonysága mellett előnye, hogy nem jár
fájdalommal. Célkitűzés: Munkánk célkitűzése a napfénnyel
végzett fotodinámiás terápia bevezetése volt klinikánkon aktinikus keratosis
indikációjában és a kezelési protokoll optimalizálása a helyi éghajlati
viszonyokhoz. Módszer: Klinikai vizsgálatunk három részből
állt. A kezelési protokollok között különbség a fényérzékenyítő anyag inkubációs
idejében és a napfényen történő kezelés időtartamában volt.
Eredmények: A nemzetközi protokoll alapján végzett
vizsgálatban az aktinikus keratosisok 73%-ában komplett, 27%-ában részleges
remissziót értünk el. A szabadban eltöltött idő arányát csökkentve a lasiók
kétharmadánál teljes, egyharmadánál részleges remissziót értünk el. 100 J/cm²
feletti kezelési dózis esetén súlyos erythema megjelenését észleltük a kezelést
követő 24 órában. Ennek elkerülésére dozimetria segítségével határoztuk meg a
szabadban eltöltött kezelési időt. A betegek a kezelést jól tolerálták, a lasiók
15%-ában részleges, 85%-ában teljes remissziót értünk el.
Megbeszélés: A módosított nemzetközi protokoll alapján
végzett „daylight” fotodinámiás terápia hatékony és jól tolerálható kezelési
eljárás az aktinikus keratosis indikációjában. Következtetés: A
napfénnyel végzett fotodinámiás kezelést sikerrel adaptáltuk és alkalmazzuk
klinikánkon a mindennapi gyakorlatban aktinikus keratosisok kezelésében. Orv
Hetil. 2022; 163(36): 1422–1429.

Abstract
Absztrakt:
Bevezetés: Az őrszemnyirokcsomó-biopszia (SNB) jelentősége az
előrehaladott – 4 mm-nél vastagabb – melanomák kezelésében eddig vitatott volt a
szakirodalomban. Manapság azonban az adjuváns terápiák alkalmazásának
előfeltétele a regionális nyirokcsomók érintettségének szövettani igazolása.
Ugyanakkor az SNB szükségességének kritériumai Magyarországon sem egységesek,
van, ahol jelenleg a vastag melanomák esetén nem végzik el ezt a beavatkozást.
Célkitűzés: Klinikánkon az elmúlt években konzekvensen
elvégeztük az őrszemnyirokcsomók vizsgálatát 4 mm-nél vastagabb melanomák esetén
is, így érdemesnek tartottuk értékelni, hogy ebben a betegcsoportban milyen
arányban fordul elő a tájéki nyirokcsomók klinikailag nem, szövettanilag viszont
detektálható áttéte. Módszer: A klinikánkon 2007 és 2011 között
melanomával diagnosztizált 1133 beteg közül kiválasztottuk azokat a pácienseket,
akiknek 4 mm-nél vastagabb primer tumoruk volt, és retrospektíven értékeltük a
betegek demográfiai adatait, primer daganatuk klinikai, valamint szövettani
jellegzetességeit az őrszemnyirokcsomó szövettani paramétereinek függvényében.
Eredmények: Az 5 éves időszakban 116 olyan, melanomában
szenvedő beteget diagnosztizáltunk, akinél vastag melanoma került sebészi
kimetszésre. 78 páciensnél történt SNB, mely 50 esetben szövettanilag pozitívnak
bizonyult. A betegek átlagos életkora közel 58 év volt.
Következtetés: Klinikánkon évente tíz olyan, vastag
melanomás beteget kezelünk, akinél az őrszemnyirokcsomó szövettani pozitivitása
alapján igazoltuk a betegség metastaticus stádiumát. Eredményeink és a Nemzeti
Rákregiszter adatai alapján akár 100 körülire becsülhető azoknak a pácienseknek
a száma Magyarországon, akiknél ezzel a patológiai stádiumot meghatározó
módszerrel az adjuváns kezelés szükségessége megállapítható. A betegcsoport
fiatal életkorát figyelembe véve, hatékony target/immunterápia adjuváns
alkalmazásával eredményesebben csökkenthető lehet az elvesztett életévek száma,
mint a belszervi metastaticus stádiumban megkezdett kezelésekkel. Orv Hetil.

Abstract
INTRODUCTION The dry and scaly skin of psoriatic patients decreases the efficacy of ultraviolet B (UVB) phototherapy. Different agents are used to facilitate the transmission of light, but most of these preparations are cosmetically unfavorable. We have tested a novel preparation containing sodium hyaluronate and nicotinic acid (UV Fotogel®; Pernix Ltd.) with the double aim to improve the efficacy of UVB phototherapy and assess the cosmetic acceptability of the preparation. METHODS Ninety patients with plaque psoriasis were enrolled in the study, of whom 44 received narrow-band UVB (NB-UVB) phototherapy. Prior to phototherapy, one side of the patient's body was treated with UV Fotogel while the other side served as a control. The other 46 patients used the preparation at their homes before regular sunbathing. The Local Psoriasis Severity Index (L-PSI), cosmetic acceptability and tolerability were recorded. The median values with the 25th and 75th percentiles (25p and 75p, respectively) were determined for the UV Fotogel-treated and control sites and then compared. RESULTS The sides of the body to which UV Fotogel was applied prior to NB-UVB phototherapy had a significantly lower median L-PSI score than the non-treated control sides at the end of the treatment (1.0 [25p-75p: 0.0-2.0] vs. 2.0 [1.0-3.0], respectively). The application of UV Fotogel prior to sunbathing also led to a significant decrease in L-PSI score. There was a significant reduction in the median L-PSI score of patients at the final visit compared to baseline (2.5 [25p-75p: 1.5-3.5] vs. 6.0 [6.0-7.0], respectively). Use of the preparation was not accompanied by considerable adverse effects, and the patients found it cosmetically acceptable. Application of UV Fotogel prior to sunbathing was well tolerated by the patients, and the cosmetic acceptability was also good. CONCLUSION UV Fotogel is potentially a useful device for enhancement of the efficacy of phototherapy in patients with psoriasis.

Abstract
BACKGROUND Acral lentiginous melanoma (ALM) occurs on the palms, soles and subungual surface and has poor prognosis. It is uncommon in the Caucasian population and has remained unreported in East-Central Europe. OBJECTIVES Our aim was to collect data from East-Central Europe by analysing the demographic and clinicopathologic features of patients with ALM and comparing data with the reports in literature. METHODS We conducted a single-centre, retrospective review between 1976 and 2016 at one of the largest melanoma referral centres in Hungary. RESULTS We identified 176 patients with ALM (3.83%) from 4593 patients with melanoma (mean age: 66.2 years). The tumours were mainly located on the lower extremities (88.63%). The mean Breslow tumour thickness was 3.861 mm, 37.50% of the tumours were thicker than 4.00 mm, and 71.6% exhibited microscopic ulceration. Nearly one-third of the patients underwent sentinel lymph node (SLN) biopsy, and 60.3% of the biopsies were positive for metastasis. The positive SLN status was associated with significantly thick tumours and reduced survival. Patients with ALM had 5- and 10-year overall survival rates of 60.5% and 41.6%, respectively. The mean delay in diagnosis was 18 months after the discovery of skin tumours. In multivariate analyses, age, tumour thickness and distant metastasis were independent risk factors for poor survival (P < 0.001). CONCLUSIONS Our study, which is the first single-centre report in East-Central Europe focusing on ALM, confirms that patient and tumour characteristics and prognostic factors are similar with previous literature data involving Caucasians; however, tumour thickness and survival suggest even worse prognosis.

Abstract
Cutaneous Squamous Cell Carcinoma (cSCC) is the most common and fastest-increasing cancer with metastatic potential. Long non-coding RNAs (lncRNAs) and circular RNAs (circRNAs) are novel regulators of gene expression. To identify mRNAs, lncRNAs and circRNAs, which can be involved in cSCC, RNA-seq was performed on nine cSCCs and seven healthy skin samples. Representative transcripts were validated by NanoString nCounter assays using an extended cohort, which also included samples from pre-cancerous skin lesions (actinic keratosis). 5,352 protein-coding genes, 908 lncRNAs and 55 circular RNAs were identified to be differentially expressed in cSCC. Targets of 519 transcription factors were enriched among differentially expressed genes, 105 of which displayed altered level in cSCCs, including fundamental regulators of skin development (MYC, RELA, ETS1, TP63). Pathways related to cell cycle, apoptosis, inflammation and epidermal differentiation were enriched. In addition to known oncogenic lncRNAs (PVT1, LUCAT1, CASC9), a set of skin-specific lncRNAs were were identified to be dysregulated. A global downregulation of circRNAs was observed in cSCC, and novel skin-enriched circRNAs, circ_IFFO2 and circ_POF1B, were identified and validated. In conclusion, a reference set of coding and non-coding transcripts were identified in cSCC, which may become potential therapeutic targets or biomarkers.

Abstract
Calcium electroporation (Ca-EP) is a new anticancer treatment providing similar features to electrochemotherapy (ECT). The aim of our study is to compare the efficacy of Ca-EP with bleomycin-based ECT. This double-blinded randomized controlled phase II study was conducted at the Medical University of Szeged, Hungary. During this once only treatment up to ten measurable cutaneous metastases per patient were separately block randomized for intratumoral delivery of either calcium or bleomycin, which was followed by reversible electroporation. Tumour response was evaluated clinically and histologically six months after treatment. (ClinicalTrials.gov: NCT03628417, closed). Seven patients with 44 metastases (34 from malignant melanoma, 10 from breast cancer) were included in the study. Eleven metastases were taken for biopsies, and 33 metastases were randomised and treated once. The objective response rates were 33% (6/18) for Ca-EP and 53% (8/15) for bleomycin-based ECT, with 22% (4/18) and 40% (6/15) complete response rates, respectively. The CR was confirmed histologically in both arms. Serious adverse events were not registered. Ulceration and hyperpigmentation, both CTCA criteria grade I side effects, were observed more frequently after bleomycin-based ECT than for Ca-EP. Ca-EP was non-inferior to ECT, therefore, it should be considered as a feasible, effective and safe treatment option.

Abstract
INTRODUCTION AND AIM Melanoma is a highly aggressive tumour with often unpredictable outcome. Our aim with this study was to determine factors influencing early detection of melanoma. METHOD We analyzed 139 questionnaires completed by patients diagnosed with melanoma. RESULTS We found that our patients are health-conscious regarding cardiovascular diseases and attend cancer screenings on recall. However, their knowledge about melanoma is insufficient. Most of them perform skin self-examination, but they do not know what to check. Melanoma is detected mostly by the patients themselves, but it takes more than one year to consult a doctor. Our study confirmed that patients' attitude toward melanoma is an important factor influencing early detection. We found that physical examination and communication about skin cancer prevention is not part of the routine medical care. CONCLUSIONS It is important to improve knowledge about melanoma among the general population and health care providers and to emphasize that early detection can save lives. Orv.

Abstract
Gorlin-Goltz syndrome is a rare multisystemic disease, characterized by numerous basal cell carcinomas. The ideal approach for patients with the syndrome would be a treatment with a high cure rate, minimal scarring, short healing time and mild side-effects. Electrochemo-therapy is a novel therapeutic option that ablates tumours with electrical current and simultaneously administered anticancer drugs. Three patients with Gorlin-Goltz syndrome were treated with electrochemotherapy using intravenous bleomycin. Clinical response was obtained in 98 (99%) of the lesions, 86 (87%) of them showed complete response. In 2 tumours, regression was confirmed with histological examination. Long-term cosmetic results were excellent. We consider electrochemotherapy to be an additional tool in the therapeutic armamentarium for Gorlin-Goltz syndrome, and suggest using it as early as possible in selected patients to avoid disfiguring scarring.

Abstract
Melanocortin-1 receptor (MC1R) and agouti signaling protein (ASIP) play pivotal roles in the regulation of human pigmentation. We aimed to study whether single nucleotide polymorphisms (SNPs) of the MC1R and ASIP genes contribute to the pathogenesis of the polygenic pigment skin disorder, vitiligo. The PCR-amplified, full-length MC1R gene was studied with sequence analysis, and the 3' untranslated region (3' UTR) SNP of ASIP was detected using restriction fragment length polymorphism. The allele frequency of the ASIP SNP did not show any difference between the skin type, hair color and eye color-matched 97 vitiligo patients and the 59 healthy control individuals. As one of the MC1R polymorphisms showed significantly higher incidence among fair-skinned individuals (Fitzpatrick I+II, n=140) than among dark-skinned individuals (Fitzpatrick III+IV, n=90), both vitiligo patients and controls were divided into two groups and the frequency of the MC1R alleles was studied separately in fair-skinned and dark-skinned subgroups of diseased and healthy groups. C478T, one of the MC1R SNPs studied in 108 fair-skinned vitiligo patients and in 70 fair-skinned healthy control individuals, showed a significant difference (P=0.0262, odds ratio [95% confidence interval]=3.6 [0.0046-0.1003]) in allele frequency between the two groups: the allele frequency was higher in the control group, suggesting protection against vitiligo. Computer prediction of antigenicity has revealed that the Arg160Trp amino acid change caused by this SNP results in a decrease in antigenicity of the affected peptide epitope.

Abstract
Non-melanoma skin cancers are the most common skin tumors. Because of their frequent localization on the face and hand, aesthetic aspects of the therapeutic procedures should also be considered. Surgical excision still remains the first choice, but recently several new alternative therapies have emerged, especially for the treatment of superficial skin cancer. Photodynamic therapy has become a widely accepted therapeutic method for certain non-melanoma skin tumors. Photodynamic therapy involves the use of light to activate a photosensitizer, localized in diseased tissues. Photosensitizers are tumor-selective: their accumulation in rapidly proliferating cells and newly formed blood vessels is significantly higher than in the surrounding healthy tissues. During photodynamic therapy, cytotoxic reactive oxygen species are formed from the photosensitizer, leading to changes in subcellular pathways or apoptosis of the cells. Efficacy of the photodynamic therapy has been proven in solar keratosis, superficial basal cell carcinoma and morbus Bowen, with significantly better cosmetic outcome than that of the conventional therapeutic methods. Side effects, like erythema, crusting, serous discharge, or oedema, are usually moderate, and dissolve rapidly. The present article summarizes the authors' experiences with photodynamic treatment (212 non-melanoma skin cancer patients were treated with PDT between December 2003 and January 2006), at the Department of Dermatology and Allergology, University of Szeged, Hungary, and reviews the literature of photodynamic therapy in dermatooncology.

Abstract
BACKGROUND Narrow-band ultraviolet B phototherapy is an effictive and safe treatment for atopic dermatitis. We have previously found that the 308 nm xenon chloride excimer laser was more effective than the narrow-band ultraviolet B light for the treatment of psoriasis, suggesting that ultraviolet B laser might offer advantages over narrow-band ultraviolet B. OBJECTIVE The purpose of this study was to evaluate the therapeutic efficacy of the 308 nm excimer laser in atopic dermatitis. PATIENTS AND METHODS Fifteen patients with atopic dermatitis (less than 20% body area involvement) were treated with a xenon chloride excimer laser (XTRAC laser, Photomedex Inc.) twice weekly. The severity of the atopic dermatitis was assessed via (i) a clinical score characterizing the intensity of erythema, infiltration, lichenification and excoriation; (ii) the quality of life, determined by means of a questionnaire; and (iii) a visual linear analogue scale, with which the patients scored the severity of their pruritus. RESULTS After 1 month of laser therapy, the clinical scores were significantly lower than the initial values. Similar decreases were observed for the quality of life and pruritus scores. No serious or unpleasant side-effects were observed. CONCLUSION These results suggest that the xenon chloride excimer laser is an effective and well-tolerated treatment for localized atopic dermatitis.

Abstract
In the present pilot investigation, the susceptibility of T-lymphocytes from Alzheimer's disease (AD) subjects (n=22) and aged-matched, non-demented controls (CNT) (n=12) was examined with ultraviolet (UV) B light-induced apoptosis in vitro. The basal apoptotic ratios were similar in both groups. However, the AD lymphocytes displayed significantly (p<0.0001) lower apoptotic levels than those of the CNT lymphocytes at all of the applied UVB exposure doses (100, 200 and 300 mJ/cm(2)). These observations indicate that AD lymphocytes are more resistant than CNT lymphocytes to UVB irradiation.

Abstract
It has been suggested that platelet-activating factor (PAF) plays a role in the pathomechanisms of various inflammatory diseases. In an experimental animal model we demonstrated earlier that a selective PAF receptor antagonist gel inhibits ultraviolet-B (UVB) light-induced edema in mouse ears. The goal of our present investigation was to determine whether locally applied WEB 2086, a selective PAF receptor antagonist, alters the dermatitis-causing effect of UVB light on human skin. We induced dermatitis in healthy volunteers by irradiating their skin with UVB light in increasing doses. The irradiated area was treated with WEB 2086 gel (3%) or with a placebo. Erythema was measured spectrophotometrically after 24 and 48 h. After both 24 and 48 h, the WEB 2086 gel significantly inhibited the UVB light-induced erythema at each radiation dose in comparison with the placebo. The PAF antagonist gel therefore proved to be effective against UVB-induced dermatitis. Our results may help to understand the relative importance of mediators in UVB-induced dermatitis and might perhaps pave the way to better therapeutic modalities in this condition.

Abstract
Earlier we reported that a 308-nm xenon chloride (XeCl) UVB laser is highly effective for treating psoriasis. As ultraviolet B light seems to cause T cell apoptosis, in the present study we studied the ability of the XeCl laser to induce T-cell apoptosis in vitro, and then compared the apoptosis-inducing capacities of narrow-band UVB (NB-UVB) light and the XeCl laser. The role of laser impulse frequency and intensity in the therapeutical and apoptosis-inducing efficacy of XeCl laser was also investigated. Both XeCl laser and NB-UVB induced T cell apoptosis, but quantitative induction was greater with XeCl laser. Changes in the frequency and intensity of impulses of XeCl laser did not influence its therapeutic and T cell apoptosis-inducing efficacy. These results suggest that the more effective induction of T cell apoptosis can be responsible for the greater clinical efficacy of XeCl laser compared to NB-UVB. Additionally, the optical properties of the XeCl laser (a monochromatic, coherent, pulse-mode laser; easier precise dosimetry, there are no 'contaminating' wavelengths) can make this laser light an ideal tool for studies of the mode of action of UVB light.
