✦ Synopsis

We examined 30 surgically removed gallbladders with ultrasound using a 10 MHz transducer in a water bath. The sonographic structure of gallbladder wall was imaged as 5 layers. The layer 3, a well-defined hyperechoic zone, was confirmed histologically as corresponding to the boundary between subserosa and muscularis. Since the spreading of gallbladder carcinoma beyond the muscle coat is an important prognostic indicator, high resolution images may well be used to advantage in assessing gallbladder wall penetration intraoperatively, enabling the surgeon to choose the proper operative procedure.

## Abstract We reviewed data on 467 patients with advanced gastric carcinoma, taking into consideration tumor size, shape and depth of invasion, and growth pattern, either expanding or infiltrative. Three patterns of penetration were identified: i.e., funnel, column, and mountain patterns. The funn

Background. The purpose of this study was to investigate the incidence of micrometastases from squamous cell carcinomas of the upper aerodigestive tract in neck dissection specimens, and to determine whether features of the primary tumor might be of prognostic value for metastasizing. Methods. Seve
