关于皮肤癌的发生率,国内外报导不一。在一些国家,如澳大利亚(BETISARIO·1959)报告皮肤鳞状细胞癌发生率约占所有恶性肿瘤50％。据我国各地资料统计,皮肤癌的发生率约在所有肿瘤的5—10位,并占所有恶性肿瘤的3％左右。为了进一步探讨皮肤癌的治疗问题,首先需要建立近似人类皮肤癌的实验动物模型。目前全世界约有 With regard to the incidence of skin cancer, reports have been mixed at home and abroad. In some countries, such as Australia (BETISARIO 1959), the incidence of cutaneous squamous cell carcinoma reports about 50% of all malignant tumors. According to statistics from all parts of China, the incidence of skin cancer is about 5-10 in all tumors and accounts for about 3% of all malignant tumors. In order to further explore the treatment of skin cancer, it is first necessary to establish an experimental animal model that approximates human skin cancer. Currently around the world
