Twenty-four Chinese NPC patients under 25 years of age at the time of diagnosis were interviewed. The interviews were carried out in the presence of their families in 22 cases and concentrated on the environmental background of the subject's infancy and early childhood. An analysis of the results eliminated household inhalants, aerial contaminants, medicines, food therapy, spices, fresh foods and soya sauce as likely factors in carcinogenesis. The only remaining foods eaten by all subjects and worthy of consideration were laap cheung, salted fish and tau si. Salted fish was the most commonly eaten and the only one fed to babies. In childhood, the subjects had rarely or never been fed vegetables or fruits. Most had, since childhood, been characteristically sickly, inactive, withdrawn and choosy about their food. It would appear that consumption of salted fish and vitamin C-deficiency in early childhood are important environmental factors and that a certain personality type may be associated with an increased risk.
对24名确诊时年龄在25岁以下的中国鼻咽癌患者进行了访谈。其中22例访谈是在患者家属在场的情况下进行的，访谈主要集中在患者婴儿期和幼儿期的环境背景。对结果的分析排除了家用吸入剂、空气污染物、药物、食疗、香料、新鲜食物和酱油作为致癌的可能因素。所有受试者都食用且值得考虑的唯一剩余食物是腊肠、咸鱼和豆豉。咸鱼是最常食用的，也是唯一喂给婴儿的食物。在童年时期，受试者很少或从未被喂过蔬菜或水果。大多数人从小就体弱多病、不爱活动、性格内向且挑食。看来童年时期食用咸鱼和维生素C缺乏是重要的环境因素，并且某种性格类型可能与风险增加有关。
