Fiberscopic diagnosis of gastric carcinoma: results of a two-stage screening.

After preliminary screening, 162 cases of gastric carcinoma were diagnosed by fiberscopy. Microscopic study revealed that 13 of these cases, i. e. 8% were in the early stage. The clinical features of these early cases are analysed. It is concluded that 1. persistent gastric symptoms call for fiberscopic investigation even if the previous finding was negative. 2. The relative youth dose not exclude early gastric cancers. 3. Improvement of the detection rate of early gastric carcinoma rests with the use of fiberscopy in combination with gastric biopsy.
