    Absztrakt: A melanoma előfordulási gyakorisága az életkorral nő, legnagyobb arányban a nem hispániai fehérekben fordul elő. Bár az ocularis melanoma gyakorisága a töredéke a cutan melanomáénak – az összes melanomás eset mintegy 4%-a, éves incidenciája 0,6 : 100 000 –, a szemtumorok között a leggyakrabban előforduló malignitás. Az ocularis és a cutan melanoma együttes előfordulása irodalmi ritkaságnak számít. Közleményünkben egy 80 éves férfi esetét prezentáljuk, akinél 2008-ban cutan nodularis melanomát excindáltak. Szemészeten 2013-ban fokozódó visuscsökkenés miatt uvealis melanomát diagnosztizáltak, amelyet brachytherapiával kezeltek. Képalkotó vizsgálatokkal és biopsziával 2015-ben melanoma hepaticus propagatiója igazolódott. A primer cutan laesio mutációanalízise BRAF V600 K típusú funkciónyerő mutációt igazolt, míg az áttétben a vad típusú gén jelenlétét mutattuk ki. Onkoteam javaslata alapján 2015 augusztusában intraarterialis májkemoterápia kezdődött, melyből 11 ciklust kapott meg, 21 napos időintervallumokkal. A beteg a kezelést jól tolerálta, mellékhatás nem jelentkezett. A 2016. februári CT a májban lévő laesio parciális regresszióját igazolta; a tizenegyedik ciklus intraarterialis májkemoterápiáját követően a beteg komplett remisszióba került, amely több mint egy évig tartott. Az ocularis és a cutan melanoma szinkrón előfordulása igen ritka, metasztatikus progresszió esetén ugyanakkor az optimális onkoterápia kiválasztása komoly kihívást jelent. A két melanomatípus molekuláris patológiai háttere eltérő, amely segítheti a metasztatikus laesiók eredetének azonosítását és az optimális, személyre szabott kezelés megválasztását. Orv Hetil. 2018; 159(16): 642–647. | Abstract: The incidence rates of cutaneous melanoma in non-Hispanic whites show an increasing tendency with age. While uveal melanoma in general is a rare disease, representing only 4% of all melanomas with an incidence rate of 0.6 per 100 000, it is still the most frequent malignancy of the eye. Synchronous occurrence of ocular and cutaneous melanoma is an exceptional rarity, due to the distinct genetic background of the diseases. We report the case of a 80-year-old man who underwent total excision of a cutaneous melanoma in 2008. In 2013, he was diagnosed with uveal melanoma as part of a routine work-up for reduced vision. The uveal melanoma was treated by brachytherapy. In 2015, liver metastases were suspected by routine ultrasonography. Core biopsy was carried out, and the histology confirmed melanoma metastases. The molecular analysis of the cutaneous lesion showed gain of function mutation of the BRAF V600 K gene, while we found a wild-type BRAF gene in the metastatic lesion. Based on the recommendation of the oncoteam, hepatic intra-arterial Epirubicin-Platidiam therapy was introduced. He received 11 doses of intra-arterial chemotherapy (IAC), in 21 cycles. IAC was well tolerated without any catheter-related complications or toxicities. Partial regression of the hepatic metastases were documented in February 2016. After completing the eleventh cycle of intrahepatic chemotherapy, the disease remained in complete remission for over a year. The parallel occurrence of cutaneous and ocular melanoma is rare, however, the metastatic progression in such cases make the selection of optimal medical therapy challenging. The distinct genetic background of two melanoma types may help the identification of the source of the metastatic lesions, in order to guide the treatment decisions.

    Anti-PD-1 Monotherapy in Advanced Melanoma—Real-World Data from a 77-Month-Long Retrospective Observational Study

    Real-world evidence plays an important role in the assessment of efficacy and safety of novel therapies. The increasing use of immune checkpoint inhibitors (ICIs) in patients with advanced melanoma has led to notably improved clinical outcomes, while they are also associated with immune-related adverse events (irAEs). The majority of the available data are based on clinical trials, where the investigated subjects often do not adequately represent the general patient population of the everyday practice. Although there is a niche of objective biomarkers for the future treatment response of ICIs, certain studies suggest that irAEs may be predictive. The aim of this study was to carry out a retrospective analysis of treatment data from patients with advanced melanoma, treated with a single anti-PD-1 agent (pembrolizumab or nivolumab) during a 77-month-long period. Treatment efficacy and occurrence of adverse events were analyzed to identify potential predictive markers. Primary and secondary endpoints were the overall survival (OS) and progression-free survival (PFS). In our cohort, we demonstrated that the occurrence of more than one irAE showed a correlation with response to PD-1 ICI therapy and improved the OS and PFS. Our study suggests, that the grade of toxicity of the irAE may affect the survival rate

    Background: The systemic treatment of advanced cutaneous squamous cell carcinoma (cSCC) has seen significant developments in recent years. The anti-PD1 inhibitor cemiplimab has demonstrated efficacy in clinical trials, but real-world data are still limited. Here, we aimed to evaluate the efficacy and the safety of cemiplimab in a real-world clinical setting. Methods: A retrospective analysis was carried out for all patients who received at least two doses of cemiplimab at our department between February 2020 and January 2023. Progression-free survival (PFS), overall survival (OS), the objective response rate (ORR), the disease control rate (DCR) and adverse events (AEs) were evaluated. Results: Twenty-five patients were included with a median age of 78 (65–82) years. The median treatment duration was 48 (16–72) weeks. Five (20%) patients were immunocompromised. Sixteen patients (64%) developed AEs, including 36% serious AEs (SAEs) of grade ≥ 3. Six patients (24%) were withdrawn from treatment due to the occurrence of AEs. Among the 25 patients, 52% showed an objective response (3 complete and 10 partial responses), 76% had controlled disease and 24% experienced progression. Among the five immunocompromised patients, the ORR was 60%, while the DCR was 80%. Conclusions: This retrospective real-world study revealed that locally advanced or metastatic cSCC could be effectively treated with cemiplimab even in elderly, polymorbid and immunocompromised patients
