Treatment of refractory, unresectable cutaneous squamous cell carcinoma presents a great challenge in head and neck oncology with poor prognosis. Prior case reports have shown off-label pembrolizumab, a programed cell death receptor antagonist, can be effective in unresectable cutaneous squamous cell carcinoma. Furthermore, prior reports have suggested enhanced efficacy when high mutational burden is present. In this study we present a severe case of unresectable cutaneous squamous cell carcinoma invading the orbit and cavernous sinus with documented tumor mutation. The patient had a complete response to palliative, off-label pembrolizumab therapy.
难治性、不可切除的皮肤鳞状细胞癌的治疗在头颈部肿瘤学中是一项巨大挑战,预后较差。先前的病例报告显示,程序性细胞死亡受体拮抗剂帕博利珠单抗用于非适应证时,对不可切除的皮肤鳞状细胞癌可能有效。此外,先前的报告表明,当存在高肿瘤突变负荷时疗效会增强。在本研究中,我们报告了1例严重的不可切除皮肤鳞状细胞癌侵犯眼眶和海绵窦且有肿瘤突变记录的病例。该患者接受姑息性、非适应证帕博利珠单抗治疗后获得完全缓解。
