Combination therapy of gastric atypical epithelium and elevated type early gastric cancer with high frequency current and laser.
A total of 11 lesions, consisting of elevated type early gastric cancer and atypical epithelium of more than 2 cm in diameter which were found in 9 cases, were jumbo biopsied using high-frequency current and the specimens obtained were examined histologically. Based on the results, the final diagnosis was established in terms of the benign or malignant nature of the lesions, some modifications were made in the irradiation method in accordance with the depth of invasion of the gastric cancer, and the adequacy of the irradiation therapy was examined. Then, the remaining tumor was irradiated with laser. This combination therapy of high frequency current and laser can make up for the drawback associated with laser therapy which does not permit collection of specimens for pathohistological study.
