[Prognostic value of the cellular expression of carcinoembryonic antigen (CEA) in gastric adenocarcinoma].

Fifty resected gastric adenocarcinomas were studied retrospectively to evaluate survival factors. Eleven different criteria were assessed using multivariate analysis. Only two criteria were significant: 1--cellular expression of carcinoembryonic antigen (p less than 0.0001 - CCR = 1.48) 2--intravascular or lymphatic tumor emboli (p less than 0.006 - CCR = 2.06). Thus, it is suggested that in addition to the various prognostic factors available to the surgical pathologist, the presence of cellular expression of carcinoembryonic antigen in tumor tissue will aid in predicting the prognosis of patients with gastric carcinoma.

Hematologic and immunologic effects of the systemic administration of recombinant interleukin-2 after autologous bone marrow transplantation.

T cells from allogeneic bone marrow grafts are responsible for a graft versus leukemia effect. Use of recombinant Interleukin-2 (rIL-2) after autologous bone marrow transplantation (BMT) may enhance immune function and hopefully reproduce the allogeneic reaction. We report here the hematologic and immunologic changes observed in the first 10 patients of a phase 1 trial studying the infusion of IL-2 after autologous BMT. All patients had high-risk malignancies and received 6 days of a constant infusion of IL-2 (Eurocetus, Amsterdam, The Netherlands) at dose of 3 x 10(6) Cetus Units/m2/d, 79 +/- 12 days after autologous BMT. Clinical toxicities involving cutaneous, cholestatic, gastrointestinal, and hemodynamic effects occurred during IL-2 treatment but reversed in all cases. Completion of treatment was 91% of the scheduled dose of IL-2. Hematologic toxicity was moderate and transient with no graft failure. Increases in eosinophil and lymphocyte counts were significant (P less than .05). Stimulation of the immune system was intense and prolonged, manifested by increase numbers of CD3+, CD3+DR+, CD3+ CD25+ lymphocytes, and natural killer (NK) cells (all P less than .01), and increase of Lymphokine-activated killers (LAK) and NK activities (P less than .01 and P less than .05). This study establishes the feasibility of a 6-day administration of rIL-2 after autologous BMT leading to a major immune activation 2.5 months after BMT.

[Adenomyoma of the distal common bile duct. An uncommon cause of stenosis of the extrahepatic bile duct].

We report the case of a 68-year-old man with adenomyoma of the distal common bile duct, fortuitously discovered on a surgical specimen of a Whipple procedure. To our knowledge, three similar cases have been reported; all patients were operated on with the diagnosis of malignancy: adenomyoma was always discovered on the surgical specimen. Adenomyomas are rare tumors and their origin is discussed. Adenomyoma of the distal common hile duct should be considered as enteropancreatic heterotopia.

[Comparative study of fine needle aspiration and large caliber needle biopsy under echographic control for the diagnosis of abdominal tumors].

The aim of this study was to compare the results of fine needle aspiration (22 G) with large caliber needle biopsy (18 G) in patients suspected of having abdominal malignancy. From November 1988 to December 1989, 73 patients aged 32 to 78 years (mean 66 years), suspected sonographically of having hepatic malignancy (66 cases) or extrahepatic tumors (7 cases), underwent ultrasonography guided percutaneous fine needle aspiration (22 G) and biopsy with a large caliber needle (18 G). There were no complications. Overall sensitivity for diagnosis of malignancy was significantly better (p less than 0.01) with 18 G needle biopsies (91.2 percent) than with fine needle cytology (71.4 percent). Specificity was 100 percent. The distinction between primary and secondary malignant tumor was possible in 87.5 percent with the large caliber needle and in only 42.9 percent with the fine needle (p less than 0.001). Histological findings were adequate hepatic metastases in 86.5 percent with the 18 gauge needle and in 51.4 percent with the 22 gauge needle (p less than 0.001). In the 7 extra-hepatic tumors, the 18 G biopsy was always positive whereas fine needle cytology was positive in only 5 out of 7 cases. Correct diagnosis for benign diseases was possible in 7 out of 10 cases with the large caliber needle whereas the fine needle cytology was always negative. These results show the superiority of large caliber needle (18 G) compared to fine needle (22 G) guided punction for both diagnosis of malignancy and origin of the tumor. Complications did not occur more frequently than with fine caliber needles.

[Mucinous cystadenocarcinoma of the appendix. A rare tumor of the right iliac fossa].

An observation of a mucinous cystadenocarcinoma of the appendix, in the tumor form, revealed by a painful syndrome of the right iliac fossa in a 62-year man is reported. It is a rare malignant tumor as less than 0.5% of the appendicectomy parts present a malignant mucosecreting tumor. In our observation, the diagnosis was allowed by pre-operation imaging. An increase of the serous amount in the tumor markers (carcinoembryonic antigen) (CEA) and CA 19-9 was found before the intervention and the immunodetections performed on the operation part were positive for CEA and CA 19-9. The serous amounts of these markers were normalized after operation. To the author's knowledge, the interest of dosing the serous tumor markers in the observation of such a type of tumor is not mentioned in the literature. The recurrences are frequent and sometimes late even when the initial excision has been macroscopically satisfactory. A new increase of the serous amount of the markers could allow for an earlier detection of a recurrence during the patient follow-up. At present, the prognosis of these malignant forms remains very poor as the 5-year survival does not exceed 25%.

[Value of upper digestive fibroscopy in the evaluation of initial spread of malignant extradigestive non-Hodgkin's lymphomas. Results in 101 patients].

The aim of this prospective study was to assess the frequency of gastroduodenal involvement during initial staging of extradigestive non Hodgkin's lymphoma. One hundred and one patients (64 men and 37 women; mean age 57.7; range 22-77 years) underwent an upper digestive endoscopy with multiple biopsies before any treatment. The origin of lymphoma was nodal in 76 cases and extranodal in 25 cases. Biopsy specimens were taken from all gross lesions; when the mucosa was considered as normal, biopsy specimens were obtained from the corpus, the antrum, and the duodenum. Endoscopy was normal in 37 patients; nevertheless in 4/37 patients, biopsies revealed lymphoma infiltration. In 64 patients, endoscopy showed macroscopic anomalies: biopsies were negative in 47 patients and showed lymphoma involvement in 17 patients. The involvement site was the corpus of the stomach (11 cases), the antrum (9 cases), and the duodenum (9 cases); lesions were multifocal in 10/21 patients. The association of several types of lesions was noticed in 5 patients. Lesions included volcano-like craters (8 cases), large folds of brain-like appearance (4 cases), tumors greater than 3 cm (3 cases), gastric ulcers (3 cases), erosive gastritis (3 cases), and erythematous duodenitis (2 cases). Overall, 21 of 101 patients (20.8 percent) had positive biopsies, 17 with endoscopic lesions and 4 without. Only 5/21 patients presented upper gastrointestinal symptoms. Staging of the lymphoma changed to Stage IV in 11 patients (4 stage I, 4 stage II and 3 stage III) (10.9 percent) after gastrointestinal involvement was documented. Gastroduodenal involvement is not related to initial site (nodal or extranodal), stage of extension or grade of malignancy of the lymphoma.

[Endoscopic detection of dysplasia and subclinical cancer of the esophagus. Results of a prospective study using toluidine blue vital staining in 100 patients with alcoholism and smoking].

In spite of the development of upper digestive tract fiberoptic endoscopy (FE) within the last 10 years, early detection of esophageal carcinoma (EC) is rare except in certain high-risk groups such as patients with head and neck cancers. The aim of this study was to assess the value of a meticulous histoendoscopic examination with vital toluidine blue (TB) staining in all alcohol and tobacco abusers undergoing FE for any reason except dysphagia. In 18 months, 100 patients (90 men, 10 women) who were over 40 years old and who consumed more than 80 g of alcohol and 20 g of tobacco per day underwent FE. No patient had a history of head and neck or esophageal cancer. FE was decided in 48 patients for epigastric pain, in 28 for esophageal varices, in 8 for weight loss, in 8 for anemia, in 7 for peptic disease, and in 1 for diarrhea. Staining with TB was carried out at the end of the examination and two routine biopsies were obtained 5 cm above the lower esophageal sphincter. Specimens were obtained from each abnormal area (TB + or TB -). Clinical ENT examination was recommended for all patients. Two esophageal carcinomas (1 microinvasive, 1 in situ) and 15 cases of dysplasia were detected. Dysplasia was classified as severe in 1 case, moderate in 9 cases, and mild in 5 cases.(ABSTRACT TRUNCATED AT 250 WORDS)

[Chronic diarrhea with hypergastrinemia and achlorhydria without gastritis in a 5-year-old child].

We report a case of chronic diarrhea due to hypergastrinemia with achlorhydria but without gastritis in a five-year-old boy. Symptoms responded promptly to oral administration of hydrochloric acid and resolved completely after one year of treatment. The pathophysiologic situation in this patient closely resembled that normally seen in neonates, suggesting prolonged but nevertheless transient immaturity of gastric secretions.

[Hyperplasia of antral "G" cells. Quantitative evaluation in endoscopic biopsies].

The number of gastrin cells (G cells) and somatostatin cells (D cells) per surface unit, and the G/D cell ratio were estimated in biopsy specimens of the antrum from normal subjects without hypergastrinemia, and from patients with hypergastrinemia not induced by gastrinoma or supra selective vagotomy. Compared with normal subjects, antral G cell density and G/D cell ratio were significantly increased in patients with hypergastrinemia. A significant correlation was found between G cell density or G/D cell ratio and the integrated gastrin output values. A quantitative estimation appears therefore possible in biopsy specimens.
