Nine cases of polypoid malignant tumor of the esophagus were treated during November 1977-March 1981. There were three males and 6 females. The ages ranged from 38 to 69 years with the average of 51 years. The duration of symptoms was 1-4 months with the average of 2 months. Two of the tumors were located in the upper esophagus, 5 in the middle, and 2 in the lower. There were 8 cases of squamous cell carcinoma and one careinosarcoma. The most frequent symptom was dysphagia. X-ray examination was helpful...

Nine cases of polypoid malignant tumor of the esophagus were treated during November 1977-March 1981. There were three males and 6 females. The ages ranged from 38 to 69 years with the average of 51 years. The duration of symptoms was 1-4 months with the average of 2 months. Two of the tumors were located in the upper esophagus, 5 in the middle, and 2 in the lower. There were 8 cases of squamous cell carcinoma and one careinosarcoma. The most frequent symptom was dysphagia. X-ray examination was helpful in diagnosisi esophagoscopy and biopsy were done for definite diagnosis. All tumors grew toward the esophageal lumen with pedicles at mucous membrane. The base of the pedicle was usually small with limited infiltration. The resectability rate of these tumors was high. Radical resections of the esophagus were performed in 9 cases by left transpleural approach. End-to-side esophagogastrostomy was done in the neck in 2 cases, above the aortic arch in 5, and below the aortic arch in the remaining two. There was no postoperative complication or operative death and all patients recovered uneventfully.

本组自1977年11月~1981年3月共手术治疗食管息肉样恶性肿瘤9例。男3例、女6例,年龄38~69岁,平均51岁。症状期1~4月,平均2月。食管上段癌2例,中段癌5例、下段癌2例。8列为鳞状细胞癌,1例为癌肉瘤。进食受阻是本病的最常见症状。X线检查有助于诊断,食管镜检查可直接地看到肿瘤,也可取活检确诊。肿瘤向腔内生长,皆有蒂和食管粘膜相连,基底范围较小,浸润较浅,手术切除率高。9例均进左胸作根治性食管切除术,2例作颈部食管胃端侧吻合术,5例作胸内主动脉弓上吻合,2例弓下吻合,术后无并发症及死亡,皆痊愈出院。

Our previous work showed that the incidence rate of upper digestive tract cancer among chickens parallels the human esophageal cancer rate in the high- and low-incidence areas, and a comparative study along this line may provide important clues to the understanding of the causes and precipitating factors of esophageal cancer.

Our previous work showed that the incidence rate of upper digestive tract cancer among chickens parallels the human esophageal cancer rate in the high- and low-incidence areas, and a comparative study along this line may provide important clues to the understanding of the causes and precipitating factors of esophageal cancer. Methyl-benzylnitrosamine (MBNA) and nitrosarcosine are strong carcinogens which induce specifically esophageal and forestomach carcinomas in laboratory rodents. In an attempt to induce, esophageal cancer in non-inbred and Leghorn cocks, MBNA was administered 1-3 times a week, with 0.22 mg per dose by gavage, for as long as 998 days, the largest total dosage being 1674.86 mg. Histopathologic examination of esophageal mucosa revealed that among 44 non-inbred chickens 21 showed varying degrees of epithelial hyperplasia, 8 developed precancerous lesions (e.g. atypical hyperplasia and early epithelial infiltration), and one had an early squamous-cell carcinoma at the upper esophagus near the pharynx. The latter bird received a total of 4.19 mg MBNA in 81 days. Study of the crop epithelium showed 13 cases of hyperplasia, 11 cases' of atypical hyperplasia, and no cancer was found. Of the 26 Leghorns, 16 cases of epithelial hyperplasia and 3 cases of precancerous lesions were noted in the esophagus, and in the crop epithelium only 8 cases of hyperplasia and 3 cases of precancerous lesions were observed. But an analysis of these experimental results showed the lack of relationship between the amount and duration of MBNA administration and the development of pathologic le- sions in the pharyngo-esophagus. The esophageal carcinoma occurred in a chicken that received only 19 treatments of MBNA, while other fowls treated for longer periods of time did not exhibit more advanced pathologic changes. The data suggested, therefore, that MBNA is nulikely the cause of esophageal cancer in chickens in the high-incidence areas.It is known that nitrosamines have to be metabolized in vivo in order to form active carcinogenic metabolites. Further experiments were carried out by isolation of the liver cells and esophageal epithelial cells from rats and chickens, and cultured these cells together with V79 cells for 18-24 hours. After the addition of MBNA or diethylnitrosa-mine, the induction of 6-thioguanine-resistant mutants, SCE, and micronuclei were used as biological test systems indicating the metabolic activation of nitrosamines. The liver cells of either species can metabolize nitrosamines, however, the epithelial cells from the esophagus of chickens cannot metabolize MBNA to any significant extent. The result demonstrated further that there is a species and organ specificity in nitrosamine car-cinogenesis, and MBNA, an esophageal carcinogen in rats, could not induce cancer of the esophagus in chickens.

试图用甲基苄基亚硝胺(MBNA)诱发鸡的食营癌,在70只鸡中,部分的食管和嗉囊中有上皮增生和癌病变,一例为早期癌,但病变的发生与MBNA处理的时间和总剂量不相关,表明是“自发性”癌变,而非MBNA诱发的。体外实验,鸡的食管上皮细胞不能代谢MBNA,不能诱导V_(79)细胞的SCE,微核及6-TG抗性突变,亦说明MBNA不能诱发鸡的食管癌。

A case of heterotopic gastric mucosa in the upper esophagus was reported. The etiology and nomenclature were discussed. It is considered that congenital factor plays the main role while acquired and inducing factors are secondary.

作者报道一例高位食管胃粘膜异位症。重点讨论病因及命名。认为先天性因素是基础,是主要的;后天获得性刺激是诱因,是次要的。早于Barrett报导本病46年前,就有Schridde报道食管柱状上皮覆盖的事实。这也是学者们研究本病的核心问题。因此,作者认为应称之为“食管胃粘膜异位症及其合并症”。
