宫颈小细胞癌(small-cell carcinoma of the cervix,SCCC)是罕见的神经内分泌恶性肿瘤,占宫颈癌的3%～5%,是一种具有高度侵袭性的宫颈癌,以早期淋巴结和血行播散为特征,即使在临床上病灶仅局限于骨盆,预后也很差。国际妇产科联盟(FIGO)...宫颈小细胞癌(small-cell carcinoma of the cervix,SCCC)是罕见的神经内分泌恶性肿瘤,占宫颈癌的3%～5%,是一种具有高度侵袭性的宫颈癌,以早期淋巴结和血行播散为特征,即使在临床上病灶仅局限于骨盆,预后也很差。国际妇产科联盟(FIGO)Ⅰ～ⅡA期患者的5年总生存率为36.8%。广泛转移的SCCC患者,5年总生存率为0,而且复发性疾病是无法治愈的,并且复发疾病诊断后的生存期很短,通常只有7～8个月。SCCC经常快速地远处转移至肺、肝、脑、骨、胰腺和淋巴结,导致大多数情况下治疗失败。SCCC治疗以手术辅以放化疗为主,综述SCCC非手术治疗方法,旨在提高SCCC的非手术治疗效果,改善患者的预后。展开更多
