肠道类癌的化疗因该病鲜见且无实验动物模型而进展缓慢。以往的治疗主要是缓解症状,联合化疗不能延缓肿瘤生长并可引起诸多副作用。作者多年从事胃肠道癌肿的实验研究并寻找新型无毒性药物,证明生长激素释放抑制因子和α-二氟甲基鸟氨酸(DFMO)可抑制动物和人类肠道癌肿的生长,最近作者又证明长效生长激素 Chemotherapy of intestinal carcinoids has progressed slowly due to the rareness of the disease and the absence of experimental animal models. The previous treatment was mainly to relieve symptoms, and combined chemotherapy could not delay tumor growth and could cause many side effects. The author has been engaged in experimental studies of gastrointestinal cancer for many years and searched for new non-toxic drugs. It is proved that growth hormone releasing factor and α-difluoromethylornithine (DFMO) can inhibit the growth of intestinal cancer in animals and humans. Long-acting growth hormone
