默克尔细胞癌(MCC)是一种侵袭性皮肤神经内分泌癌(Ahmed et al.,2021年)。非病毒MCC(MCCN)由过度暴露于UVR引起,而多瘤病毒相关MCC(MCCP)由默克尔细胞多瘤病毒的克隆整合引起(Feng et al.,2008年)。MCCP肿瘤组成型表达病毒大T和小T抗原(Ahmed等人,2021年)。TP53在MCCP中经常是野生型(WT),并且在MCCN中经常改变(Knepper等人,2019).尽管MCCP和MCCN肿瘤的病因不同,但它们具有相似的临床特征和治疗策略(Schrama et al.,2011年)。MCC通过手术切除后进行辅助放射治疗来管理(Bichakjian等人,2018年)。单独的放射治疗导致与手术相似的存活率(Patel等人,2018年)。放射敏感性已显示与头颈部鳞状细胞癌中的病毒状态相关(Rieckmann等人,2013年)。
Merkel cell carcinoma (MCC) is an aggressive skin neuroendocrine cancer (Ahmed et al., 2021). Nonviral MCC (MCCN) is caused by excessive exposure to UVR, whereas polyomavirus-associated MCC (MCCP) is caused by clonal integration of Merkel cell polyomavirus (Feng et al., 2008). MCCP tumors constitutively express the viral large T and small T antigens (Ahmed et al., 2021). TP53 is frequently wild type (WT) in MCCP and often altered in MCCN (Knepper et al., 2019).Despite their distinct etiologies, MCCP and MCCN tumors have similar clinical features and treatment strategies (Schrama et al., 2011). MCC is managed by surgical excision followed by adjuvant radiation therapy (Bichakjian et al., 2018). Radiation therapy alone leads to survival rates similar to those of surgery (Patel et al., 2018). Radiation sensitivity has been shown to be associated with viral status in head and neck squamous cell carcinoma (Rieckmann et al., 2013).
