제안 방법
- Twenty three patients had early gastric cancer and 10 patients had advanced gastric cancer. After dividing them into early gastric cancer and advanced cancer, the macroscopic findings, the location of lesion, the area and the long axis were compared and analyzed. No differences were detected (Table 5).
- In our study, the sizes of the category 3 and 4 lesions were not different, and so it is difficult to guess the category of dysplasia based on the size only prior to resection. For the comparison of the size of lesion, this was analyzed by two methods by using the area and the length of the long axis. Nonetheless, the results were not different, and so it is thought that the analysis of the size of lesion by using only the long axis is adequate.
- In addition, the 33 patients diagnosed with invasive cancer after resection were divided in to the early gastric cancer and advanced gastric cancer groups, and the correlation of the macroscopic findings of the lesion according to the depth of invasive and the lesion’s location and size was analyzed.
- The correlation of the grade of gastric epithelial dysplasia with the macroscopic findings of the lesion and the lesion’s location, and size was analyzed.
- It was found that the category of dysplasia did not correlate with the macroscopic findings. The patients were divided according to the location of lesion as upper, middle and lower, and the correlation to the category of dysplasia was compared and analyzed. Similarly, the category of dysplasia did not correlate with the location of lesion (Table 2).
- We analyzed the medical record of 126 patients who were diagnosed as category 3 or category 4 by endoscopic biopsy according to the Vienna classification of gastrointestinal epithelial neoplasia on gastrofiberscopic biopsy(4) from 1999 to 2009 at the Bundang CHA Hospital. These patients subsequently underwent polypectomy, endoscopic mucosal resection, submucosal resection or gastrectomy, including lymph node dissection, and the accuracy of the diagnosis prior to and after resection was compared after performing histological re-examination. As references, category 1 is negative for neoplasia/dysplasia, category 2 is indefinite for neoplasia/dysplasia, category 3 is non-invasive low category neoplasia (low grade adenoma/dysplasia), category 4 is non-invasive high grade neoplasia, including high grade adenoma/dysplasia, noninvasive carcinoma (carcinoma in situ) as well as a suspicion of invasive carcinoma, and category 5 is invasive neoplasia, including intramucosal carcinoma and submucosal carcinoma or beyond.
대상 데이터
- Among the 56 cases diagnosed as category 4 by biopsy, there were 2 cases (9%) whose category was lowered to category 1 or category 2, there were 5 cases (9%) lowered to category 3 (9%), there were 20 cases (36%) that the biopsy and surgical category (category 4) were identical and there were 29 cases (52%) who were raised to category 5. Among the total 126 patients, there were 71 patients (56%) whose biopsy category concurred with the category after resection (Table 1).
- The thirty three category 5 patients after resection were divided into early gastric cancer and advanced gastric cancer. Twenty three patients had early gastric cancer and 10 patients had advanced gastric cancer.
