We wanted to evaluate whether skin toxicity can be used as a prognostic marker for the treatment of patients who are receiving Cmab therapy for r/mSCCHN.Methods: A retrospective review was conducted of demographic data, prognostic features, treatment responses, Cmab-related skin toxicity, and dates of diagnosis, treatment initiation, progression, and death for r/mSCCHN patients treated with Cmab at Kocaeli University Medical Oncology Department between 2010 and 2019.Significance of the results has been evaluated by using SPSS (20.0 SPSS Inc., Chicago, IL, USA.) statistical program.Results: A total of 77 patients were enrolled.A significant association was found between Cmab-related skin toxicity and longer survival in patients with r/mSCCHN. Patients without skin toxicity had shorter progression-free survival (PFS) compared to those with grade 1 and grade 2 skin toxicity. Notably, patients who had grade 3 skin toxicity exhibited longer overall survival (OS) and significantly better PFS than those without skin toxicity, as well as those with grade 1 or grade 2 toxicity. No significant OS difference was observed between patients with grade 1 or grade 2 toxicity and those without skin toxicity.Conclusions: Skin toxicity, particularly grade 3, is associated with improved prognosis, with longer OS and PFS. Grade 1 and grade 2 skin toxicity are linked to better PFS compared to no toxicity. These findings suggest that preventive strategies to manage Cmab-related skin toxicity, especially grade 2 and grade 3, may enhance patient outcomes. KW - cetuximab KW - head and neck cancer KW - skin toxicity N2 - ÖzAmaç: Rekürren veya metastatik baş ve boyun kanserinde(r/mSCCHN) Setuximab (Cmab) ile ilişkili cilt toksisitesi, tedavide sık görülen bir yan etkidir. Cilt toksisitesinin prognostik bir ölçüt olarak kullanılıp kullanılamayacağını değerlendirmek istedik. Yöntem: 2010-2019 yılları arasında Kocaeli Üniversitesi Tıbbi Onkoloji Bölümü'nde Cmab ile tedavi edilen r/mSCCHN hastalarının demografik verileri, prognostik özellikleri, tedavi yanıtları, Cmab ile ilişkili cilt toksisitesi, tanı zamanı, tedavi başlama zamanı, progresyon ve ölüm tarihleri retrospektif olarak incelenmiş ve sonuçların anlamlılığı SPSS (20.0 SPSS Inc., Chicago, IL, USA.) istatistik programı kullanılarak değerlendirilmiştir.Bulgular: Toplam 77 hasta çalışmaya dahil edilmiştir.R/M SCCHN hastalarında Cmab ile ilişkili cilt toksisitesi ile daha uzun sağkalım arasında anlamlı bir ilişki bulunmuştur. Cilt toksisitesi olmayan hastalarda, grad 1 ve grad 2 cilt toksisitesi olanlara kıyasla daha kısa progresyonsuz sağkalım (PFS) görülmüştür. Özellikle, grad 3 cilt toksisitesi olan hastalar, cilt toksisitesi olmayanların yanı sıra grad 1 veya grad 2 toksisitesi olanlara göre daha uzun genel sağkalım (OS) ve daha iyi PFS sergilemiştir. Grad 1 veya grad 2 toksisitesi olan hastalar ile cilt toksisitesi olmayan hastalar arasında anlamlı bir OS farkı gözlenmemiştir.Sonuç: Özellikle grad 3 cilt toksisitesi , daha uzun OS ve PFS ile yani daha iyi prognoz ile ilişkilidir. Grad 1 ve grad 2 cilt toksisitesi, cilt toksisitesi olmayanlara kıyasla daha iyi PFS ile bağlantılıdır. Bu bulgular, Cmab ile ilişkili cilt toksisitesini, özellikle de grad 2 ve grad 3 cilt toksisitesini yönetmeye yönelik önleyici stratejilerin hasta sonuçlarını iyileştirebileceğini göstermektedir.
