Abstract

Introduction: Vulvar squamous cell carcinomas (SCCs), although rare, are tumors with a high malignant potential and limited therapeutic options. This study aimed to investigate the expression of Lin28A—a molecule recently associated with various tumors and considered a promising target for therapy—in vulvar SCC, as well as its potential prognostic significance. Methods: Biopsies from 40 cases diagnosed with vulvar SCC were retrospectively re-evaluated, and Lin28A immunohistochemical staining was applied to suitable tumor blocks. Clinical and pathological features were recorded. Results: The mean age of the patients was 69.05 years, with a mean follow-up duration of 53.5 months. Recurrence was observed in 56.8% of cases, and mortality was recorded in 69.2%. Lin28A positivity was detected in 42.1% of tumors. Significant associations were found between greater depth of invasion, advanced clinical stage, recurrence, and mortality. Although a higher mortality rate was noted in Lin28A-positive cases, the difference was not statistically significant. Conclusions: This study represents the first report investigating Lin28 expression in vulvar SCC, a molecule previously studied in various malignancies such as gastric, lung, liver cancers, and head and neck SCC, where it has been shown to have an adverse prognostic impact. Although the prognostic effect could not be definitively demonstrated due to the limited sample size, a relatively high expression rate was observed. Lin28 may represent a potential therapeutic target, particularly in cases presenting with recurrence and metastasis.

Özet

Giriş: Vulvar skuamöz hücreli karsinomlar (SHK), nadir görülmelerine rağmen yüksek malign potansiyele sahip ve tedavi seçenekleri sınırlı tümörlerdir. Bu çalışma, son zamanlarda çeşitli tümörlerle ilişkili olduğu bildirilen ve tedavi açısından umut verici bir hedef olarak değerlendirilen Lin28A molekülünün vulvar SHK’daki ekspresyonunu ve olası prognostik önemini araştırmayı amaçlamaktadır. Yöntem: Vulvar SHK tanısı almış 40 olguya ait biyopsiler retrospektif olarak yeniden değerlendirildi ve uygun tümör bloklarına Lin28A immünohistokimyasal boyama uygulandı. Klinik ve patolojik özellikler kaydedildi. Bulgular: Hastaların ortalama yaşı 69,05 yıl, ortalama takip süresi ise 53,5 aydı. Olguların %56,8’inde nüks, %69,2’sinde mortalite saptandı. Tümörlerin %42,1’inde Lin28A pozitifliği gözlendi. Daha derin invazyon, ileri klinik evre, nüks ve mortalite arasında anlamlı ilişkiler bulundu. Lin28A pozitif olgularda mortalite oranı daha yüksek olmakla birlikte fark istatistiksel olarak anlamlı değildi. Sonuç: Bu çalışma, vulvar SHK’da Lin28 ekspresyonunu araştıran ilk çalışmadır. Lin28, mide, akciğer, karaciğer ve baş-boyun SHK gibi çeşitli malignitelerde daha önce incelenmiş ve olumsuz prognostik etkiyle ilişkili bulunmuştur. Örneklem sayısının sınırlı olması nedeniyle prognostik etkisi kesin olarak gösterilememekle birlikte, göreceli olarak yüksek bir ekspresyon oranı saptanmıştır. Lin28’in özellikle nüks ve metastazla seyreden olgularda potansiyel bir terapötik hedef olabileceği düşünülmüştür.
