Whang-Peng notes that after many years, gene therapy for cancer faces three intractable hurdles: one is how to introduce genes into human cells; the next is how to control the positioning of the gene once introduced, and the third is how to control the gene's function-there is still no reliable way to enable or inhibit their expression.
彭汪嘉康指出，多年來，癌症的基因治療一直卡在 3 個難關上無法解決，一是要如何將基因帶入人體細胞中；其次，基因帶入細胞後，位置無法掌控，再加上基因的功能仍無法控制，如何讓它正常表現或適時停止，仍然沒有可行的方法。
