 Gastric biopsy by fiberscope is now a most safe and effective method of examination as exemplified by the positive results of 95 percentage both in early and advanced gastric cancer.

 In this paper we have examined very minute carcinomas less than 5 mm in diameter in which biopsy showed positive results for cancer. Accurate biopsy is indispensable to the diagnosis of such small lesions. In the biopsy of early cancer, histologic diagnosis of biopsy specimens must take into account that of border lesions for the differentiation between benign and malignant lesions. Such close communication between clinicians and pathologists are also necessary for the diagnosis of false-negative cases of advanced carcinoma or of malignant lymphoma.

 We have studied 11 cases in which follow-up biopsies demonstrated cancer. At the initial gastric biopsy they were negative for cancer and endoscopically they were diagnosed either as early cancer or benign lesions. The reasons for the initial failure to detect cancer by the biopsy were considered insufficient observation by endoscopy, faulty technics of biopsy and failure to correctly diagnose pathological specimens. As the gastric biopsy has become an easy and safe procedure, it has become a tool for an easy-going examination method on the supposition that as long as it is performed the diagnosis could be made without difficulty. We have reported here that such an attitude may entail false management on the patients. Gastric biopsy should be done on lesions detected by the screening procedure of the gastrocamera aimed at the entire stomach. Discrepancy between endoscopic diagnosis and that of biopsy should be corrected not only by re-biopsy but also by close cooperation between the clinician and pathologist.
