幼儿呼吸道乳头状瘤（ＲＰ）的治疗远未解决，以手术切除为主，但手术不能预防复发，术后用ＩＦＮ制剂（如肌注人白细胞ＩＦＮ，ｒｅａｆｅｒｏｎ等）抗复发的疗效令人鼓舞，但幼儿肌注这类制剂的可能副作用（如致热原反应，贫血，白细胞和血小板减少，转氨酶升高）促使另寻新 The treatment of infantile papilloma of the respiratory tract (RP) is far from being resolved. Surgical resection is the main method, but surgery can not prevent recurrence. The efficacy of anti-recurrence after IFN preparation (such as intramuscular injection of human leukocyte IFN, reaferon, etc.) is encouraging. However, possible side effects (such as pyrogenic response, anemia, leukocyte and thrombocytopenia, and elevated transaminases) in infants with intramuscular injections of this kind of preparations have prompted another search for new ones.
