Aug 6, 2021 · What is the most common histologic type of early gastric carcinoma? What is the most important prognostic factor of early gastric carcinoma?

Sufficient knowledge on the appearance of EGC on white light endoscopy is fundamental for early detection and management . Each macroscopic type, discussed in the section below, has typical endoscopic findings for the different types of EGC, such as intestinal or diffuse.

Superficial or early neoplasias in the entire GI tract are primarily assessed on the basis of their endoscopic appearance and are defined as type 0 (for other types, see the endoscopic classification of advanced tumors); the “0” is usually omitted in clinical practice — for example, “type IIa” instead of “type 0-IIa.”

Type 0-II is divided into three types: 0-IIa (slightly elevated type), 0-IIb (flat type), and 0-IIc (slightly depressed type). Type 0-IIc is the most common type of EGCs. EGCs often appear as a mixture of types, in which case the major type is followed by the minor type (e.g., 0-IIb+IIa, 0-IIc+IIa).

현재 사용하고 있는 조기위암 분류법은 내시경 소견에 기초한 gross classification입니다. 간혹 논문에서 병리 분류를 사용하기도 하는데, 이는 차선일 뿐입니다. 내시경 육안소견을 바탕으로 한 real time 분류가 정답입니다.

Dec 26, 2021 · With the development of different endoscopic diagnostic modalities for EGC, several classifications have been advocated for the evaluation of gastric lesions, aiming for an early detection and diagnosis.

Most hereditary early-onset gastric carcinomas are concentrated in the corpus-fundus of young women. By histology, the most common EGC type is tubular adenocarcinoma in many growth patterns, starting in the neck of a gastric unit.

Core Tip: Early gastric cancer (EGC) is an invasive stomach cancer confined to the mucosal or submucosal lining and represents approximately 20% of gastric cancers in Western countries. A correct classification allows the most appropriate treatment.

Mar 31, 2013 · Type 1 to 5 is classified as advanced gastric cancer (AGC). 4 With more detailed insights, type 0 was further classified into EGC as follows; EGC type I (elevated), EGC type II (flat, a, b, c), and EGC type III (excavated) based on endoscopic morphology by Japanese Society of Gastrointestinal Endoscopy.

early gastric cancer (EGC) in whom the 5-yr survival rates are between 80% and 95% {4-6). Early gastric cancer is defined as carcinoma that is limited to the gastric mucosa and submucosa and that does not ex tend into the muscularis propria (5,7).
