BACKGROUND Because gastrointestinal cancers are generally firm, the presence and extent of a tumor can be assessed by touch during surgery. However, an objective scale for evaluating tissue hardness does not exist. We developed a new instrument, the endoscopic ultrasonic tactile sensor, that allows objective evaluation of hardness. In this study the usefulness of this device for diagnosis of th...

PURPOSE Replication error is an important mechanism in carcinogenesis. The microsatellite instability (MSI-H) of colorectal cancers is associated with the development of multiple cancers. The influence of MSI-H on the development of multiple gastric cancers in sporadic gastric cancer patients has not been defined. This study was performed to reveal the association between the clinicopathologic ...

Significant advances in the detection and treatment of initial cancers increase likelihood life-threatening subsequent primary cancers, particularly for long-term survivors. A brief patient case regarding a Hodgkin lymphoma survivor with gastric cancer will demonstrate how care providers can identify potential using American Cancer Society website.
