Twenty specimens from patients who had undergone oesophagectomy for invasive squamous carcinoma of the oesophagus were examined for morphological evidence of human papillomavirus infection; it was found in 13 specimens. Nineteen specimens showed focal epithelial hyperplasia of the non-neoplastic mucosa. The material was also submitted to immunoperoxidase and modified Feulgen staining to detect viral antigen. Positive Feulgen staining was detected in the superficial layers of the squamous mucosa in 15 specimens, while immunoperoxidase was entirely negative. This demonstrates a possible association between human papillomavirus and oesophageal carcinoma and that the modified Feulgen method may be more sensitive than immunoperoxidase for the detection of viral antigen. Electron microscopy and molecular hybridisation would have to be used for confirmation.

Monoclonal antibody 7B10, raised against the human breast cancer cell line T47D, identifies an antigen found in human breast carcinomas and in normal breast. Western blot and immunoprecipitation studies detected a Mr 76,000 antigen in cytosol, cell membrane, and cell culture supernatants of T47D cells. 7B10 binding to T47D cell extracts was affected by proteolytic digestion with protease type VI, trypsin, and subtilisin while it was not altered by neuraminidase digestion. Adsorption of breast cancer cell line extracts with concanavalin A reduced 7B10 immunoreactivity more than 70%. These results suggest that the antigen is a glycoprotein and that the epitope does not contain sialic acid. 7B10 was reactive with neither human milk fat globule membrane, nor skimmed milk, nor the milk-derived HBL 100 cell line. Conversely binding was detected in more than 50% of normal breast epithelial cells in culture. 7B10 immunostaining was positive on frozen sections of normal breast and nonmalignant mastopathies in 30 to 90% cells. In frozen sections of other normal tissues, 7B10 immunoreactivity was detected only in colon, apocrine glands of skin, parotid ducts, and luteal phase endometrium, confirming previous data on paraffin sections. Strong, homogeneous immunostaining was observed on frozen sections of intraductal and invasive lobular breast carcinomas (100% of cases), while more heterogeneous staining was found on invasive ductal carcinomas. Colon and rectal carcinomas, one carcinoma of the esophagus, and some cells in serous ovarian carcinomas also showed 7B10 reactivity. Immunoblotting of the 7B10-immunoreactive fraction isolated by Sepharose CL-6B chromatography of a breast carcinoma tissue sample extract identified the Mr 76,000 antigen, which was also detected in several breast cancer specimens, in colon adenocarcinomas, and in serous ovarian carcinoma fresh tumor extracts. The Mr 76,000 glycoprotein described here represents a breast cancer-associated antigen previously undescribed, mainly expressed in normal breast and breast tumors.

A retrospective analysis of 453 patients with carcinoma of the oesophagus and gastric cardia was carried out in order to identify the incidence, operative findings, and outcome of patients who underwent laparotomy only without a definitive procedure. Of 343 patients who underwent surgery, 81% had their tumours resected and 15% had a bypass procedure. The remaining 14 patients (4%) had an exploratory laparotomy alone. The incidence of performing a laparotomy only was 1.5% for patients with carcinoma of the thoracic oesophagus but was 14% for patients with tumour of the gastric cardia (P less than 0.001). The reasons for exploration alone in these 14 patients were advanced local disease (12), bilobar liver metastases (seven), extensive abdominal lymph node metastases (seven), peritoneal seedlings (six) and malignant ascites (four). All except one patient had more than one feature which led to the decision of exploration only. As the overall incidence of exploratory laparotomy was low, it would not be appropriate for all patients to undergo exhaustive and expensive investigations. Surgical exploration continues to be the only reliable method to determine the actual extent of disease and whether a definitive procedure is possible. However, patients with cancer of the cardia with clinical features of advanced disease might warrant additional evaluations as the incidence of exploratory laparotomy alone with minimal prior investigation is relatively high.

Five patients with advanced carcinoma of the esophagus were treated with a combination chemotherapy employing CDDP and BLM. One cycle of chemotherapy consisted of CDDP, 50 mg/m2, on day 1 and BLM, 15 mg/patient on days, 1, 7 and 14. Two partial remission and 2 minor responses were obtained. Overall response rates, ths, were 80%. The most adverse effect was nausea. No significant elevation in the serum creatinine or BUN was recognized. Furthermore, the method of CDDP administration was studied on the serum level by 15 minutes' infusion and by 24 hours continuous infusion. The CDDP levels in the serum and tissue were determined by flameless atomic absorption spectrophotometry. The CDDP level in the serum by 15 minutes' infusion was higher than that by 24 hours continuous infusion. These results suggest that combination chemotherapy with CDDP and BLM may be a useful method for the treatment of advanced esophageal carcinoma.

The reliability of CT scanning in assessing resectability in carcinoma of the oesophagus was investigated prospectively by direct comparison with the operative findings. Over 11 months, 38 patients judged potentially operable following conventional investigation underwent CT scanning from the thoracic inlet to the level of the adrenal glands. These patients were then explored surgically with a view to resection. The CT findings were assessed by two radiologists without access to clinical information. Operative findings were recorded by the surgeon. Comparison was made between the tomographic and surgical findings specifically assessing: longitudinal tumour extent, direct mediastinal infiltration, invasion of other mediastinal structures, lymph node involvement and the presence of hepatic and pulmonary metastases. The sensitivity and specificity of the scan for each feature was then calculated. Scan sensitivity was poor, ranging from 0%-66.7%. Specificity was better with a range of 70.8%-100% according to the criterion studied. We conclude that the poor sensitivity means that CT scanning is of little value in the preoperative assessment of resectability in oesophageal carcinoma.

Superficial squamous carcinoma of the esophagus, defined as carcinoma limited to mucosa or submucosa regardless of lymph node status, is being increasingly recognized in the Western hemisphere. Seventy-six cases of this entity are herein presented. Five macroscopic types were recognized: normal flat (eight cases), coarse (21 cases), verrucous (25 cases), polypoid (17 cases), and ulcerating infiltrating (five cases). Histological typing included 65 conventional squamous cell carcinomas, six squamous carcinomas with spindle cell features, and five adenoid cystic carcinomas. Four cases were strictly intraepithelial, 10 cases were confined to the mucosa, nine cases encroached onto the muscularis mucosae, and 53 extended into the submucosa. Cases with intraepithelial and infiltrating carcinomas confined to the mucosa showed no lymph node involvement. Thirty percent of cases extending into the submucosa developed lymph node metastases. Thirty-eight patients survived surgical resection from 1 to 96 months; 34 of these 38 were free of neoplastic disease. Fourteen patients had an associated bronchial or oropharyngolaryngeal carcinoma either simultaneously or asynchronously. We conclude that patients with superficial squamous carcinoma of the esophagus can benefit from early diagnosis and prompt surgery.

Twenty-five patients with carcinoma of the esophagus (group I) and 25 patients suffering from non-ulcer dyspepsia with normal endoscopy (group II) were studied to know the incidence of isolation of Candida from their esophagus. Endoscopic brushings were taken from the esophagus in both groups and studied by smear examination and culture. Fungal organisms could be detected in 75% of cases of group I and 32% of cases of group II by culture techniques, and 45.8% and 12% respectively by smear examination. The difference was statistically significant (p less than 0.05) for both the techniques. Candida albicans was the commonest species isolated. No correlation was found between Candida agglutination titres and density of Candida growth on culture. We conclude that an association exists between carcinoma esophagus and the occurrence of Candida in the esophagus.

As part of a consecutive series of 370 patients who underwent subtotal esophagectomy because of carcinoma of the thoracic area of the esophagus, between January 1965 and July 1988, in the Second Department of Surgery, Kyushu University Hospital, 42 patients (11.4%) with early stage esophageal carcinomas confined to the intraepithelium, mucosa, or submucosa were studied clinicopathologically. Of these 42, 26 (61.9%) had symptoms; slight dysphagia or chest discomfort was the most common symptom. The remaining 16 (38.1%) had no subjective symptoms. Endoscopic examination proved to be more useful than barium studies. Lugol-combined endoscopy was most effective in detecting the presence and spread of small malignant lesions of the esophagus. At the time of surgery, six patients with submucosal carcinoma of the esophagus had lymph node metastasis, and five died of recurrence. Described herein are the diagnostic features, clinicopathologic characteristics, and long-term results of these 42 patients with early stage, and 328 patients with advanced, carcinomas of the esophagus, detected and surgically treated in our clinics.

Hyperthermia combined with irradiation and chemotherapy was prescribed for patients with resectable (n = 88) and unresectable (n = 36) carcinoma of the esophagus. The histopathological effectiveness, and the long term results were compared between two groups of patients treated with hyperthermo-chemo-radiotherapy (HCR therapy) and those treated with chemoradiotherapy (CR therapy). A correlation between the hyperthermia sensitivity test, using the in vitro succinate dehydrogenase inhibition test, and the clinical remedial value was also examined in malignant tissues from 47 patients with esophageal cancer, and treated with HCR therapy. In the resected cases, preoperative HCR therapy resulted in a significantly higher histopathological effectiveness rate (69%) compared with that in cases treated by CR therapy (48%) (P less than 0.05). The long term results of patients with both resectable and unresectable carcinoma, given HCR therapy were significantly better than those given CR therapy (P less than 0.05). On the other hand, the clinical remedial value, determined radiographically showed a correlation rate of 77% to the hyperthermia sensitivity test. Thus, the HCR therapy resulted in not only a higher histopathological effectiveness rate but also a significantly longer survival without severe side effects, and this hyperthermia sensitivity test using the succinate dehydrogenase inhibition test facilitates prediction of the outcome of the HCR therapy.

Six patients with small, superficial carcinoma of the esophagus were treated with 18-24 Gy of high-dose-rate intracavitary irradiation only. All patients were examined with an endoscope within 1 month after therapy, and the tumor in all six had disappeared. However, erosion induced by high-dose-rate intracavitary irradiation was seen in five of the patients. Five of the patients have experienced no local recurrence; endoscopic biopsy showed local recurrence in the remaining patient 7 months after radiation therapy. All patients have survived 6-16 months. Esophageal ulceration induced by intracavitary irradiation occurred in three of the six patients; however, the ulcers have been healing with conservative treatment. This new method of using only high-dose-rate intracavitary irradiation appears to be effective in the patient with small, superficial esophageal carcinoma.
