食管癌是我国最常见的癌症之一。在党的领导下,华北三省一市(河南、河北、山西、北京)早已进行防治协作研究,其进展情况本刊已屡有报道。四川、湖北、广东、江苏、广西、新疆等省、自治区由于也有高发区或相对高发地区,近年来也正在开展工作。自1974年春起,中国科学院和不少其他非医务单位也参加了综合调查研究。今年8月11日至17日在石家庄举行第四次三省一市防治研究协作会议,各有关单位都有代表参加,交流经验,并制订1975～1976年的协作计划。从会议情况可见,在毛主席的革命卫生路线指引下,在坚持贯彻落实毛主席《六·二六》指示的基础上,依靠群众的力量,近一年余来又取得了不少进展,其主要部分几乎全是在现场调查研究中取得的。 Esophageal cancer is one of the most common cancers in our country. Under the leadership of the party, three provinces and one city in north China (Henan, Hebei, Shanxi and Beijing) have long been engaged in research on prevention and control and its progress has been repeatedly reported in this issue. Provinces and autonomous regions in Sichuan, Hubei, Guangdong, Jiangsu, Guangxi and Xinjiang also have been carrying out their work in recent years because of their high incidence or relatively high incidence. Since the spring of 1974, Chinese Academy of Sciences and many other non-medical units have participated in the comprehensive investigation and study. This year, from the 11th to the 17th of August this year, the fourth collaborative meeting for prevention and control research in three provinces and one city was held in Shijiazhuang. All relevant units attended the meeting and exchanged experiences and formulated the collaborative plan for 1975-1976. As can be seen from the meeting, under the guidance of Chairman Mao’s revolutionary health line and on the basis of consistently implementing Chairman Mao’s “June 26” directive and relying on the power of the masses, much progress has been made in the past year and more Almost all of the major parts were obtained during on-site investigation and research.
