  screening for gastric cancer
Mass screening for gastric cancer in Japan has been conducted nationwide since 1960.
      
A suitable cut-off point in screening for gastric cancer was a pepsinogen I level of less than 50 ng/ml and a I/II ratio of less than 3.0, as determined by receiver operator characteristics curves.
      
These results suggest that, in screening for gastric cancer when using pepsinogen levels and morphological examinations, the suitable cut-off point in regard to specificity is as stated above.
      
In Japan, mass screening for gastric cancer with photofluorography was initiated in 1960.
      
Among the other 111 patients, 97 were shown to have stromal tumors on upper gastrointestinal series or endoscopy during screening for gastric cancer.

The samples of sera from 188 patients with various benign gastric diseases, 100 patients with gastric cancer, and from 100 normal individuals were determined for the contents of acid soluble glycoproteins (ASP). The serum ASP contents (X±SD) were 1.042±0.231g/L in normal individuals, 1.07±0.394g/L in patients with chronic superficial gastritis, l.l56±0.312g/L in patients with gastric ulcer, 1.238 ±0.220g/L in pateints with chronic atrophic gastritis and 2.198±0.958g/L in psteints with gastric cancer.

The samples of sera from 188 patients with various benign gastric diseases, 100 patients with gastric cancer, and from 100 normal individuals were determined for the contents of acid soluble glycoproteins (ASP). The serum ASP contents (X±SD) were 1.042±0.231g/L in normal individuals, 1.07±0.394g/L in patients with chronic superficial gastritis, l.l56±0.312g/L in patients with gastric ulcer, 1.238 ±0.220g/L in pateints with chronic atrophic gastritis and 2.198±0.958g/L in psteints with gastric cancer. The regular alteration of the contents of serum ASP during the process of gastric canceration was found. For evaluating the serum ASP assay, the X + 2SD of serum ASP contents in normal individual (1.504g/L) was selected as the cut off point. The positive results were respectively found 2.0% in normal individuals, 16,0% in patients with various bening gastric diseases and 78,0% in patients with gastric cancer, The results suggested serum ASP assay might be of clinical significance.

Results: With the excitation of 200 nm ultraviolet rays,three emission bands with gradually reduced nuorescence intensity were appeared in the wavelength...

Objective: To investigate the significance of The serum autofluorescence spectra in the diagnosis ofgastric cancer. Methods: The serum autofluorescence spectra were measured with spectrofluorophotometer in agroup of 93 patients with verified gastric carcinoma, including 19 patients in the early stage, and anothergroup of 1098 patients with non-malignant diseases. Results: With the excitation of 200 nm ultraviolet rays,three emission bands with gradually reduced nuorescence intensity were appeared in the wavelength of 320nm, 400 ~ 500 nm, 700 nm, respectively. The serum autofluorescence spectra in the group of gastriccarcinoma showed difference from those in the group of non-malignant diseases. The 400 ~ 500 nm emissionband was significantly increased in intensity and in a saw-shape with dual, triple or multiple peaks. A smallemission band called the 4th band was also explored near 620 nm. With the canonical discriminant function: C=1.3X1+1.5X2+2.0X3-1.5X4, The positive rates of early gastric carcinoma and advanced gastriccarcinoma were 78. 9% and 9O. 5 %, respectively, and showed a significant difference from those of non-malignant diseases. Conclusion: The result showed that the serum autofluorescence spectroscopy was aneffective approach to the screening and dingnosis of gastric carcinoma.
