Thermal injury resulting from drinking very hot beverages has been incriminated as a risk factor for oesophageal cancer, although no information is available on the lesions caused by this injury in human or experimental animals. The drinking of hot maté tea is very common in areas of moderately high incidence of oesophageal cancer in south-eastern areas of South America. This study investigated the prevalence of precancerous lesions of the oesophagus in 60 unskilled male workers, of whom half were daily maté drinkers and the remainder were non-maté drinkers. These 2 groups were matched for age, smoking and alcohol intake. Maté drinkers were 2.2 times more likely (p = 0.046) to develop histologically confirmed oesophagitis than non-maté drinkers.
饮用非常热的饮料导致的热损伤被认为是食管癌的一个风险因素，尽管目前尚无关于这种损伤在人类或实验动物中所造成病变的相关信息。在南美洲东南部食管癌发病率中等偏高的地区，饮用热马黛茶的情况非常普遍。本研究调查了60名非技术男性工人食管前癌病变的患病率，其中一半是每日饮用马黛茶者，其余为不饮用马黛茶者。这两组在年龄、吸烟和饮酒量方面进行了匹配。饮用马黛茶者发生组织学确诊食管炎的可能性是非饮用马黛茶者的2.2倍（p = 0.046）。
