An unusual case of asymptomatic squamous cell carcinoma of the esophagus metastatic to the pancreas, mimicking a rare primary pancreatic neoplasm, is reported. Percutaneous fine needle aspiration (FNA) biopsy of a pancreatic lesion showed squamous cell carcinoma, which in the pancreas is virtually always metastatic in origin. This prompted a search for an occult primary elsewhere, resulting in the discovery of an esophageal neoplasm, which in itself is one of the least likely sources of pancreatic metastases. FNA biopsy was thus a useful and accurate diagnostic tool in establishing the true nature of the pancreatic neoplasm, sparing the patient unnecessary pancreatic surgery, with its attendant morbidity and hospital costs.

Biopsy tissues from a 68-year-old Japanese man with metastases to axillary lymph nodes of a recurrent esophageal carcinoma were adapted to cell culture conditions and a continuously growing tumor cell line was developed. Immunohistochemical staining revealed that these cells contained keratinous material and the electron microscopic study revealed the presence of tonofilaments. Thus, this line, designated the KSE-1 line, was considered to have originated from metastatic squamous cell carcinoma of the esophagus. This line has a binding content of 4.2 fmol/mg protein for the estrogen receptor and 2.2 fmol/mg protein for the testosterone receptor. By measurement of cell number and thymidine incorporation, the growth rate of this line was found to be moderately responsive to these hormones, being inhibited by estrogen and enhanced by testosterone at concentration levels between 10(-13) and 10(-8) and 10(-13) and 10(-6) mg/ml, respectively.

Based on a retrospective review of nine patients with adenocarcinoma in a Barrett's esophagus and the reports of similar cases in the literature, a staging system for this malignancy was devised. A progression of changes could be identified that corresponded to the stages. These changes consisted of dysplasia progressing to carcinoma in situ and invasive malignancy with metastases. Stage III disease carried the same grim prognosis as a similar stage of squamous cell carcinoma of the esophagus. Earlier stages of adenocarcinoma of the esophagus appeared to have a better prognosis. White men with symptoms of reflux esophagitis, esophageal strictures, and/or hiatal hernias who have Barrett's esophagus extending proximal to the distal 10 cm of the esophagus appear to have a propensity to develop adenocarcinoma of the esophagus. Consideration should be given to antireflux surgery and close follow-up by periodic esophagoscopy and biopsy of the esophagus in these patients. If neoplasia is found, the thoracic esophagus should be totally removed with the stomach or left colon anastomosed to the cervical esophagus. Because of the poor prognosis of Stage III disease, postoperative chemotherapy should be considered.

The fibrinolytic activity of 156 malignant and 36 benign solid tumors from autopsy and biopsy specimens was studied by the fibrin slide technique. The inhibitory activity against fibrinolysis was graded according to the lysis time of vascular tissues within the tumor. The results show that all malignant solid tumors, with the exception of prostate carcinoma, demonstrated varying degrees of inhibition of fibrinolysis. Persistently high inhibitory activity was found in squamous cell carcinoma of the esophagus, the respiratory tract, cervix uteri, and skin; carcinoma of uterus; colorectal carcinoma; small cell anaplastic carcinoma of lung; neuroblastoma, carcinoma of bile duct, while malignant tumors of the kidney show a lesser degree of inhibition. In contrast, with the exception of the hydatidiform mole, benign solid tumors show little or no inhibition. A similar absence of fibrinolytic activity is seen in metastatic disease. Further studies of the role of the fibrinolytic system in tumors seems warranted.

The most common initial symptom of esophageal neoplasm is dysphagia. When metastasis occurs, it is most frequent to neighboring lymph nodes, mediastinum, or viscera, eg, the lungs and liver, and only infrequently to bones. Even less frequently do these metastases occur with hypercalcemia. A 59-year-old woman was initially seen with hypercalcemia and bone pain in the hip and leg, which subsequently proved to be the site of metastatic spread secondary to squamous cell carcinoma of the esophagus. Until her death, approximately four months after the diagnosis, she never experienced dysphagia, epigastric or substernal pain, or regurgitation.

In a 4-year period (1988-1991) 122 patients with a squamous cell carcinoma of the esophagus were studied prospectively and analysed. 64 patients of them could be primary resected (primary resectability rate 52%), 36 patients were in general inoperable and 22 patients had an advanced stage of cancer with local inoperability. Due to a preoperative combined radiotherapy and chemotherapy 16 of the 22 patients with local inoperability had a clinical remission of the tumor (73%). 11 patients (50%) showed a histological verified down staging and 3 cases of them a complete remission (no primary tumor was found, no infiltration of the regional lymphnodes and no metastatic disease). Curative resection was possible in 14 of 16 patients with clinical remission (2 patients refused surgical treatment). So the resectability rate now increases from 52 to 63%. We conclude that there was no increased rate of postoperative complications or mortality in the combined radio-/chemotherapy group compared with the primary resected patients.

Tenascin, a large glycoprotein of the extracellular matrix, is involved in cell proliferation, differentiation, and migration during embryogenesis. In adult tissue, it is expressed only in certain areas. However, it gains importance again in proliferative processes such as wound healing and especially in tumor development. We examined paraffin-embedded specimens of 25 patients with a squamous cell carcinoma of the esophagus, 5 patients with an adenocarcinoma of the small intestine, 4 patients with a carcinoid tumor of the small intestine, and 49 patients with an adenocarcinoma of the colorectum. Immunohistochemical staining was performed by the use of a monoclonal antibody against human tenascin and the avidin-biotin-complex technique. Amino-Ethylcarbazol served as a chromogen. We investigated the distribution of tenascin in tumors, normal tissue, and lymph node metastases and compared it to tumor grading and TNM-classification. We found a uniform pattern of tenascin expression in all tumors and lymph node metastases examined in the gastrointestinal tract. One pattern was characterized by an immunoreaction near the basement membrane in well-differentiated areas and the other showed a diffuse, network-like expression in poorly differentiated areas with abundant stroma. There was a more intensive staining of the surrounding stroma near tumor cells invading into the submucosa or muscularis propria. It was even possible to detect small early carcinomas as well as small tumor cell populations in and around the lymph nodes by a strong immunostaining of the surrounding stroma. But we could not find any correlation of the tenascin expression patterns in comparison to the tumor grading and TNM-classification.

The results of surgical treatment of 65 patients with pT1 squamous cell carcinoma of the esophagus and the histologic workup of the specimens were analyzed. The treatment of choice was transthoracic enbloc esophagectomy (n = 45); in 16 patients with very distal carcinoma and restrained lung function transhiatal esophagectomy was performed. Two patients with concomitant early gastric carcinoma or lymphoma had total esophagogastrectomy, and in 2 other patients cervical esophagectomy was performed. The postoperative 30-day mortality was 6.1%. 74% of the cases had an infiltration of the submucosa, whereas in 26% the carcinoma was limited to the mucosa. No patients with mucosal carcinoma had lymph node metastases, whereas 23% of the patients with submucosal infiltration showed lymph node involvement. Tumors of other organs, especially stomach and hypopharynx, were found in 15.4% of the patients. The 5-year survival rate of the total group of 65 patients was 61.3%. As 3 patients with mucosal carcinoma died during long-term follow-up due to recurrence or second cancer, no significant prognostic difference was found between patients with mucosal or submucosal infiltration. The survival curves of patients with pN0 and those with pN1 tumors were not significantly different.

Cancers from patients with tumor-induced hypercalcemia usually produce a circulating factor that mimics the parathyroid hormone activity, termed parathyroid hormone-related protein. Incidence of tumor-induced hypercalcemia appears to be high in patients with squamous cell carcinoma of the esophagus, and the presence of parathyroid hormone-related protein have been shown in some primary esophageal cancers. In the present study, we have investigated the presence of parathyroid hormone-related protein in a patient with metastasized squamous cell carcinoma of the esophagus complicated with tumor-induced hypercalcemia. Protein was searched by immunohistochemistry, and messenger RNA was investigated by reverse transcriptase-polymerase chain reaction and S1 nuclease assay. Both messenger RNA and protein were detected in hepatic metastases, whereas normal esophageal mucosa and primary cancer did not express detectable protein or messenger RNA using the S1 nuclease assay. Reverse transcriptase-polymerase chain reaction was positive in all these tissues, including normal esophageal mucosa. In conclusion, the present case suggests that tumor-induced hypercalcemia due to esophageal squamous cell carcinoma may be caused by parathyroid hormone-related protein mostly released by liver metastases.

A 60-year old male patient who had locally advanced esophageal carcinoma with bulky upper abdominal lymphadenopathy underwent neoadjuvant chemotherapy consisting of 5-fluorouracil (5-FU) and cisplatin (CDDP), followed by concurrent radiotherapy and chemotherapy using protracted low-dose continuous infusion of 5-FU and CDDP. The treatment brought about complete remission in the primary lesion and good partial remission in the upper abdominal lymphadenopathy. He subsequently underwent trans-hiatal esophagectomy after one cycle of adjuvant chemotherapy because local recurrence was suspected. Histopathologic study of the resected specimen demonstrated no malignant tissue in the primary lesion and the lymph nodes. The patient is still alive and disease-free at 26+ months. This result suggests that neoadjuvant chemotherapy followed by concomitant chemotherapy and radiotherapy for patients who have locally advanced squamous cell carcinoma of the esophagus with intensive abdominal lymphadenopathy may offer some chance for sterilization of local and regional metastases and longer survival.
