A 76-year-old woman had a verrucous carcinoma of the esophagus with a fistula of the left main bronchus. We discuss this case together with those of eleven other patients with verrucous carcinoma of the esophagus reported previously. Differentiation between this tumor and squamous cell papilloma is often difficult. The central cores of fibrous tissue in verrucous carcinoma are heavily infiltrated with inflammatory cells, which accounts for the stenosis often found. The mortality in verrucous carcinoma of the esophagus is 67% even though histologically it is a low-grade malignancy.

A 71-year-old Japanese man with basaloid-squamous carcinoma of the esophagus is reported. The carcinoma contained basaloid cells, a few small cornified foci, and a large amount of eosinophilic hyaline substance, which reacted positively upon periodic acid-Schiff, type IV collagen, and laminin staining. Ultrastructural examination revealed markedly replicated basement membranes (BM). The morphological findings suggested that this tumor secreted abundant BM substance. Small nests of cancer cells were attached to the dysplastic esophageal epithelium. The tumor cells exhibited negative staining for mucin, secretory component, lactoferrin, and carcinoembryonic antigen. These findings, as well as the observed keratinization and attachment between the carcinoma nests and mucosal epithelium, indicate that the tumor originated in the mucosal epithelium of the esophagus.

A review of 323 patients with carcinoma of the esophagus disclosed 50 cases (15.5%) with glandular and/or mucus-secreting components, in addition to the ordinary component of squamous cell carcinoma. These tumors could be grouped into three type according to representative histologic features of glandular and mucus-secreting portions: glandular type (28 cases), cribiform type (14 cases), and mucoepidermoid type (8 cases). The histologic features of the three types were reminiscent of those of adenocarcinoma, adenoid cystic carcinoma, and mucoepidermoid carcinoma of salivary glands, respectively. Moreover, areas showing glandular or mucus-secreting differentiation were in greater part located in the submucosa and the lamina propria mucosae, thereby suggesting that such differentiation had arisen in the esophageal glands or their ducts. From these findings, in addition to intraepithelial and mucosal carcinomas, carcinoma restricted to the submucosal layer without lymph node metastases should be also defined as "early" esophageal cancer and definition of it according to the existing Guide Lines for the Clinical and Pathologic Studies on Carcinoma of the Esophagus is thought to be adequate at present.

Sixteen cases of esophageal carcinoma invading the submucosa were analyzed in terms of growth patterns. Seven were classified into the massively penetrating (down growth) type, four into the superficially spreading (spreading growth) type, and five into the unclassified type. In the down growth type, the ratio of the submucosal area to the total (mucosa and submucosa) area was more than 0.2 (one fifth), and in the others that ratio was less than 0.2. The down growth type is characterized by a tendency toward elevated lesions, a high incidence of vessel invasions and lymph node metastasis, and a poor prognosis after surgery. Lymphatic and/or vascular invasions were recognized in six of seven cases, and the 5-year survival rate was 0%. In contrast, the spreading growth and unclassified types was characterized by superficial lesions, a low incidence of vessel invasions and lymph node metastasis, and a favorable prognosis. In only one with the spreading growth type was there lymphatic invasion. Three of the four with the spreading growth type survived over 5 years, and the other one with the spreading growth type and all of five with the unclassified type are alive without recurrences 15 to 52 months after surgery. Thus, growth patterns reflect well the prognosis of the submucosal carcinoma of the esophagus.

A series of 51 biopsies derived from the same number of patients with established invasive squamous-cell carcinoma of the esophagus in Linxian, a high-risk area for esophageal cancer in China, were analyzed histologically and by in situ DNA hybridization to demonstrate human papillomavirus (HPV) infection. Epithelial changes suggesting HPV infection within or adjacent to the carcinoma lesions were found in 25 cases (49.0%). Esophageal lesions with HPV morphology showed both flat (25 cases) and inverted condylomas (2 cases) resembling those found in the genital tract. HPV 6, 11, 16 or 18 DNA sequences were detected in 22/51 (43.1%) of the esophageal specimens. HPV DNA was most frequently localized in epithelium adjacent to carcinomas in areas showing either epithelial hyperplasia (36.1%) or dysplasia (22.2%). Of the lesions with morphological HPV changes, 64% (16/22) were shown to contain HPV DNA. In 2 specimens, HPV DNA was found in frankly malignant cells. High-risk types HPV 16 and/or 18 DNA sequences were found in 16 of the 22 HPV DNA-positive cases (72.7%). Our results confirm previously reported HPV involvement in esophageal squamous-cell lesions, and support the hypothesis of HPV as a possible etiological agent in esophageal carcinogenesis.

Small-cell carcinoma of the esophagus is a rare tumor and has received little attention until recent years. It should be differentiated from the far more common poorly differentiated squamous-cell carcinoma of the esophagus, because treatment by surgical resection alone or by radiation therapy results in limited survival of a few months. It is now recognized that esophageal small-cell carcinoma presents with early widespread dissemination and is chemosensitive, similar to primary small-cell carcinoma of the lung. We report on a patient with small-cell carcinoma of the esophagus treated with combination chemotherapy consisting of cyclophosphamide, vincristine, and VP-16 followed by local radiation therapy. Pathologic complete remission was achieved. The patient is currently in remission 22 months after diagnosis, the longest survival reported thus far.

Between 1969 and 1984, 251 patients with carcinoma of the esophagus were evaluated. One hundred and eleven patients underwent en bloc esophagectomy. The technique of operation is described. Hospital mortality was 11% (12/111). Complications occurred in 49 patients. There have been no recurrences of cancer more than 3 years after operation. Absolute survival at 5 years is 55%, 29%, 15%, and 8% for W1N0, W1N1, W2N0, and W1/W2N2, respectively. En-bloc resection could be accomplished for esophageal carcinoma with an acceptable mortality and morbidity. The operation is potentially curative in a small subset of patients with unfavorable prognostic factors.

Esophagogastrectomy for carcinoma of the esophagus or cardia has been performed in 32 patients with histologically proven hepatic cirrhosis. Thirty-one esophagogastrectomies were performed through a separate abdominal and right thoracic approach in 25 patients, a left thoracoabdominal approach in five patients, and without thoracotomy in two patients. One patient had a colon interposition. Seven patients died after operation (21%) as a result of anastomotic leakage in two patients, hepatorenal in four patients and portal thrombosis in one patient. The type of procedure did not influence mortality. The most common postoperative complication was the development of ascites (68%), and when associated with hepatorenal syndrome (in four patients) there was significant mortality (p less than 0.05). Sepsis was present in the terminal stages of all nonsurvivors. A prothrombin time less than or equal to 60% of normal values was the only significant preoperative predictive factor of mortality, with none of the three patients surviving below this level (p less than 0.05). It is concluded that the presence of cirrhosis is not a contraindication to esophagogastrectomy for carcinoma when curative resection can be undertaken. Hepatic reserve is the determinant factor of operative prognosis. Operative risk is acceptable if patients are classified as Child's class A, and prothrombin time is over 60% of normal values. Operation should be delayed when acute alcoholic hepatitis is present. Intraoperative discovery of cirrhosis is not a contraindication to resection when the above criteria are met.

The aim of this study is to evaluate the role of bronchoscopy in the assessment of resectability of esophageal carcinomas. From 1981 to 1986, 125 patients were referred for a carcinoma of the esophagus. Bronchoscopy was performed in 105 cases. Patients were classified into 3 groups: group I: normal bronchoscopy (58 cases: 55.2%); group II: compression, localized inflammation (35 cases: 33.3%); Group III: invasion (12 cases: 11.5%). Tracheo-bronchial abnormalities were found whatever the site of the esophageal carcinoma: 60% of cases for the upper third, 40% for the middle third and 36% for the lower third. They were significantly more frequent when the esophageal tumor was larger than 5 centimeters. Correlation with CT scan was good in 75% of cases. Sensitivity and specificity of these two exams were similar and they appeared to be complementary. In group I, resection was impossible or palliative for bronchial reasons in 10% of cases, while resection was impossible or palliative in 35% of cases in group II. Lastly, resection was curative in 73.5% of cases in group I and in only 39% of cases in group II. Bronchoscopy must be systematically performed in carcinoma of esophagus. It may predict the palliative nature of resection if abnormalities are present, and may contraindicate the resection when invasion of the bronchial tree is discovered.

Isolated local recurrence following potentially curative resection for carcinoma of the esophagus or esophagogastric junction does not necessarily imply pending systemic disease and early demise. While radiation alone or in combination with chemotherapy is standard treatment for such patients, resection is another available option. Resection may also be a consideration should localized disease persist after non-operative therapy in the absence of metastases. A 5 year retrospective review was performed examining 204 resections performed prior to 1989. Only 5 patients underwent resection of locally recurrent esophagogastric (EG) adenocarcinoma during this period. No squamous carcinoma recurrences were resected. One patient is well 15 months later while another died at 18 months of other causes without recurrence. Recurrence after re-resection occurred at 8, 11, and 24 months in the 3 other patients. Although there were no postoperative deaths, major complications occurred in 4 patients. All 5 patients swallowed normally after operation.
