A study on 50 patients with dissected gastric cancer in the E hospital has shown that the male-female ratio was 3/2. The gastric cancer rate was increased with age. The cancer in the 1/3 of lower stomach (4-%), mainly in the small curve (36%); size of tumor: 3-6 cm (36%), 6 cm (44%), early detected cancer (8%), late detected cancer (92%), chronic gastritis and atrophy (92%); intestinal heteroplasia and dysplasia (60%). The heteroplasia and dysplasia occurred more frequently in the gastric epithelioma then undifferentied gastric cancer.

The tumor marker CA 72-4 has been determined sera of gastric cancer patients to evaluate its role in the diagnosis and the monitoring of treatment. Adenocarcinoma of the stomach: 68 (38 men, 30 women; age 17-70) Gastric ulcer and gastritis: 10 (male: 8, female: 2; age 30-72). Criteria of diagnosis: cytologic examination. 40 patients have been monitored CA 72-4 during one month after operation. There were high statistical difference of CA 71-4 concentrations between cancer and healthy groups (p< 0.001); but no difference between ulcer and healthy people (p<0.005) has been found. The specificity of CA 72-4 for gastric cancer was 100%; sensitivity: 73.53%; Positive predictive value: 100%; Negative predictive value: 35.7%. 77.5% of cases had decreased levels of CA 72-4 after surgery. But in 4 cases, the increased concentrations of this marker correlated with residual tumor. The results showed that CA 72-4 proved to be specific and sensitive in the diagnosis and prognosis and monitoring of surgical treatment of gastric cancer.

The endoscopic mucosal resection is a useful method of both accurate diagnosis and treatment of gastric mucosal lesion and has been accepted as a standard procedure of early gastric cancer. Over the 3 year period from 1992 to 1994, 57 adenomas and 10 early gastric carcinomas were resected endoscopically at the St. Mary's hospital of Catholic University Medical College. The purpose of this study was to clarify the technical limitations of endoscopic mucosal resection with respect to size, location, methods. (continue...)

PURPOSE: The purpose of this study was to evaluate the performance of multidetector-row CT (MDCT) in the preoperative T-staging of patients with advanced gastric cancer. MATERIALS AND METHODS: A total of 65 patients with an established diagnosis of advanced gastric cancer (T2 or more) were evaluated with MDCT. The protocol of MDCT consisted of high-quality (HQ) mode helical scanning with a slice thickness of 2.5 mm. The axial CT images were reconstructed with a slice thickness of 5 mm. MPR images were reconstructed from the raw axial data with a slice thickness of 5 mm. A comparison between the standard axial and axial MPR images was performed by two radiologists with regard to the evaluation of the tumor location and T-stage. These findings were compared with the pathologic and surgical findings. RESULTS: T-staging of the advanced stomach cancer was correct in 89% (58/65) and 69% (45/65) of the MPR images and axial images, respectively. The MPR images improved the detection rate (5 lesions)of the tumors and increased the accuracy of the T-staging (13 lesions) in comparison with the axial images. The MPR images are of greater diagnostic value for the evaluation of omental seeding (5 lesions: axial images, 9 lesions: MPR images), tumor location and extension. CONCLUSION: Multiplanar reconstruction (MPR) images provide increased confidence in the location and T-staging of certain cases of advanced gastric cancer, such as those in locations where CT images are susceptible to be affected by the difficulties associated with partial volume averaging. In this study, the MPR images provided more precise information about the tumor location and T-staging than the standard axial images in the preoperative evaluation of advanced gastric cancer.

The quantification of markers of gastric tumors in healthy people by IRMA has shown that the serum concentrations of CA 72-4 and CA 19-9 in 49 healthy people with ages of 18-49 was 4.05 +/- 3.07 u/ml and 17.12 +/- 11.06, respectively. There was no difference of specific these markers between men and women. These results can be used to compare with markers in patients with gastric tumors.

Study was conducted cross on the sections from 3cm and 5cm of tumor upper edge of 125 patients with gastric carcinoma. Results: the percentage of existence of tissue cancer at the section that above the tumors 3cm and 5cm was 20.8% and 10.4%, respectively. The percentage of existence of tissue cancer at the cross section 3cm and 5cm was higher than invasive type in comparison with intestinal type (28.3% vs 16.5% and 15.2% vs 7.6%), in undifferentiated carcinoma, adenocarcinoma and Signet-ring cell carcinoma comparison with duct carcinoma (36.8%, 37.5% and 26.3% vs 9.7% at cross section 3cm and 21.1%, 18.8% and 10.5% vs 3.2% at cross section 5cm), in tumors with diameter >2cm and ≤5cm comparison with tumors ≤2cm (27% vs 7.1% at cross section 3cm and 14.3% vs 0% at cross section 5cm), in invasive carcinoma of sero comparison with shorter invasive carcinoma and at last in carcinoma of gland metastasis comparison with tumors without gland metastasis (4.7% vs 11.4% at cross section 3cm and 16.7% vs 4.5% at cross section 5cm).
