肿瘤干细胞学说这一新概念的提出及认定无疑将会是人类攻克癌症的一大进步,将会对癌症的诊断、治疗及预防产生深远的影响,为人类治愈癌症提供重要帮助。但目前这一研究领域仅是初级阶段,还有许多问题有待解决,如是否各种肿瘤都含有肿瘤干细胞、肿瘤干细胞的具体生物学特性、肿瘤干细胞的调节机制、肿瘤干细胞的药物研制及其疫苗的研制等等,此外近年发现的SP细胞与肿瘤干细胞的具体内在联系也是需要搞清的问题之一,因为这种细胞可能与肿瘤的耐药性有很大关系[32]。总之,肿瘤干细胞的作用机制如果得到详尽阐明,那么对包括肝癌在内的所有癌症的治疗无疑将迈入一个新世纪,对肿瘤患者来说必将是一大的福音。 6 e; a, q* v+ g!
