摘要

目的:DEK::AFF2 鳞状细胞癌是最近描述的一种癌症实体,迄今已报道 29 例。有时,这些癌症看起来难以区分;但是,特定的形态和表型特征表明存在这种重排。然而,这种诊断的预后价值仍不明确。我们旨在报告一个具有组织学、分子学和临床特征的新病例系列:我们收集了 15 例患者的数据,研究了他们的表型,包括 CK7、P63/P40、PDL1、AFF2 和 P16 的表达谱、形态学特征以及相关的预后数据。我们将这些数据与之前发表的数据一起进行了分析:这些病例大多表现出指示性形态特征,如外生性和内生性乳头状生长、核单形性和大量富含中性粒细胞的炎性浸润。免疫组化分析显示,所有患者均表达 AFF2 和鳞状细胞标志物。未检测到 P16 的过表达,而 CK7 和 PDL1 的表达则各不相同。在我们的研究队列中,发现了50%的进展或复发率、25%的淋巴结转移、17%的远处转移和18%的疾病相关死亡,且随访时间较短:结论:DEK::AFF2鳞状细胞癌的发病率可能被低估了。结论:DEK::AFF2 鳞状细胞癌的发病率可能被低估了。尽管肿瘤形态平淡,但其复发率和转移率似乎很高。我们建议将 AFF2 免疫组化作为一种有效的工具,并建立了一种诊断算法,以支持对这些肿瘤的准确诊断。

Sinonasal Squamous Cell Carcinoma with DEK::AFF2 Rearrangement : An Aggressive Cancer with Bland Morphology.

Aims: DEK::AFF2 squamous cell carcinoma is a recently described cancer entity, with 29 cases reported to date. Occasionally, these carcinomas appear deceptively indistinguishable; however, specific morphological and phenotypic features suggest the presence of this rearrangement. However, the prognostic value of this diagnosis remains unclear. We aimed to report a new case series with histological, molecular, and clinical features.

Methods: We collected data from 15 patients and investigated their phenotypes, including the expression profiles of CK7, P63/P40, PDL1, AFF2, and P16, morphological features, and associated prognostic data. We analyzed these data along with the previously published data.

Results: Most of these cases exhibited indicative morphological features, such as exophytic and endophytic papillary growth, nuclear monomorphism, and abundant neutrophil-rich inflammatory infiltrates. Immunohistochemical analysis revealed the expression of AFF2 and squamous cell markers in all the patients. Overexpression of P16 was not detected, whereas CK7 and PDL1 were expressed variably. In our study cohort, a 50% progression or recurrence rate, 25% lymph node metastasis, 17% distant metastasis, and 18% disease-related death were identified, with a short follow-up time.

Conclusion: DEK::AFF2 squamous cell carcinoma incidence is probably underestimated. The low-grade appearance of these tumors sometimes limits their detection. The rates of recurrence and metastasis seem to be high despite an often bland morphology. We propose AFF2 immunohistochemistry as an effective tool, and a diagnostic algorithm has been established to support accurate diagnosis of these tumors.
