Six patients with primary ulcerative carcinoma of the esophagus are described. The radiologic appearance is analogous to the Carman-Kirklin complex seen with gastric malignancies. The clinical course of this uncommon type of esophageal carcinoma is the same as the more common constricting and polypoid varieties.

We prospectively studied patients with Streptococcus bovis septicemia for the presence of gastrointestinal lesions. This study was prompted by our reported findings of the association of fecal carriage of S. bovis with carcinoma of the colon. We studied 29 patients with 30 episodes of S. bovis septicemia. Fifteen completed gastrointestinal evaluations that included colonscopy, surgery, or autopsy. Eight of these had carcinoma of the colon, three had adenomatous polyps of the colon without carcinoma, and two had carcinoma of the esophagus. The 14 patients who did not have complete evaluations included one each with carcinoma of the stomach, gastric lymphoma, and adenomatous polyp of the colon and three with colonic masses not further delineated. Nineteen patients had no gastrointestinal signs or symptoms or stools positive for occult blood at admission. The results of our study suggest that all patients with S. bovis septicemia need aggressive evaluation of the gastrointestinal tract, especially the colon.

Three newly found patients with an esophageal pseudosarcoma are described. The features of this unusual polypoid tumor are reviewed based on these three patients and 21 additional reported patients. The origin of the sarcomatous element as a metaplastic reaction to the underlying carcinoma is discussed. The exuberant growth may present with obstructive symptoms earlier than the usual carcinoma of the esophagus, permitting curative surgical resection in some patients.

In the light of three cases of esophageal carcinoma developing on a pre-existing idiopathic megaesophagus the authors examine etiopatological, clinical and terapeutic problems related to this association. They believe that carcinoma of the esophagus tends to be a complication of cardiospasm in patients inadequately treated for the primary condition. Early diagnosis and an adequate Heller operation for cardiospasm will lessen the chance of cancer developing in megaesophagus with stasis. When finally diagnosed, this variety of esophageal carcinoma has an extremely poor prognosis. An even more important claim upon the clinician is to be alert to the hazards of continued stasis in megaesophagus and to devise earlier techniques of recognition, including more frequent recourse to biopsy during esophagoscopy.

A clinical series of 216 patients with carcinoma of the oesophagus or cardia, who underwent surgical resection of the oesophagus, is presented. There were 104 patients with oesophageal carcinoma and 112 patients with carcinoma of the cardia. Histologically, there were 102 squamous cell carcinomas, 98 adenocarcinomas, 11 anaplastic carcinomas and 7 non-differentiated carcinomas. Oesophago-gastrotomy was the procedure mostly used; colon interposition was done in only 13 cases. The hospital mortality was 21%. The 5-year survival rate for the whole series after oesophageal resection was 23%. The duration of symptoms, location of the tumour, age and sex of the patients, pre- or postoperative radiotherapy and the histological type of the tumour had only a minor bearing on survival. The two most important prognostic factors were the spread of the tumour at time of operation and a preceding lye stricture. The 5-year survival rate was 34% for the patients with a local tumour at operation and 44% for those in whom the carcinoma developed at the site of a previous lye stricture. The variance of the results in the literature is discussed. Surgical approach to the carcinoma of the oesophagus and cardia is recommended in all the cases in which the patient and tumour seem to be eligible for resection.

In addition to lymphoma, there is an increased incidence of gastrointestinal carcinoma in patients with malabsorption due to celiac disease. This is frequently manifested by a loss of response to gluten withdrawal. Four such cases are described: one patient had lymphoma and the other three had cancer of the esophagus, jejunum, and pancreas, respectively. The literature indicates that carcinoma of the esophagus and small bowel is particularly common in patients with celiac disease. These findings suggest that celiac disease should be considered a premalignant condition and that such patients should undergo a regular radiographic survey to detect early cancer.

From 1950 to 1973, 129 patients received irradiation for esophageal squamous-cell carcinoma at the University of California, San Francisco. From this group, 26 received surgical and irradiation treatment. Twelve did not receive irradiation until recurrence became evident and among them were no 5-year survivors. Among the other 14 were six 5-year survivors (43%). The authors believe that planned sequential irradiation and surgery offer the best chance for cure in squamous-cell carcinoma of the esophagus. Selection factors, treatment details, and therapeutic regimens are presented and a management plan proposed for this group of operable patients.

Thirty-four (1%) of 3,287 patients with squamous carcinoma of the head-neck developed carcinoma of the esophagus. The clinical and radiological importance of this relationship is emphasized. Since there is an increased incidence of esophageal carcinoma in this group, perhaps all such patients should have an annual esophagogram.

The carcinogenic activity of orally administered N-bis(2-hydroxypropyl)-nitrosamine (DHPN) in male Wistar rats was evaluated with respect to its dose. DHPN was administered at two doses, 100 ppm and 500 ppm, in the drinking water to rats for 25 to 52 weeks. Tumors developed in the lung, liver, and thyroid of rats receiving 100 ppm DHPN and in the lung, liver thyroid, esophagus, kidney, and urinary bladder of rats receiving 500 ppm DHPN. The principal target organ was the lung in rats receiving either 100 or 500 ppm DHPN, indicating that the carcinogenic action of these doses of DHPN was similar to that of higher doses previously reported. Histologically, the tumors were adenoma, adenocarcinoma, squamous cell carcinoma, and combined carcinoma of the lung, hepatocellular carcinoma and hemangioma of the liver, adenoma and adenocarcinoma of the thyroid, squamous cell papilloma and carcinoma of the esophagus, renal cell and transitional carcinoma of the kidney, and transitional cell carcinoma of the urinary bladder. No pancreatic tumors were observed.

A case of pseudosarcomatous carcinoma of the esophagus with metastasis to lymph node was presented and the literature was reviewed briefly. Transition from carcinomatous to sarcomatous picture was noted and the presence of tonofibrils and desmosomes was demonstrated by electron microscope in the cells with sarcomatous features. These findings suggested an epithelial origin of the sarcomatous component in pseudosarcomatous carcinoma.
