Early gastric carcinoma confined to –
**Core Concept**
Early gastric carcinoma refers to a type of gastric cancer that is confined to the mucosa or submucosa, without lymph node involvement. This stage of cancer is often curable with surgical resection. The classification of gastric cancer is based on the depth of tumor invasion and the presence of lymph node metastasis.
**Why the Correct Answer is Right**
The correct answer is related to the Lauren classification, which categorizes gastric cancer into two main types: intestinal and diffuse. Early gastric carcinoma is typically classified as intestinal type, which is more common and has a better prognosis. The tumor is confined to the mucosa or submucosa, without lymph node involvement, making it eligible for surgical resection. The presence of lymph node metastasis would indicate a more advanced stage of cancer.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not specify the depth of tumor invasion.
**Option B:** This option is incorrect as it does not mention the absence of lymph node involvement.
**Option C:** This option is incorrect as it does not specify the type of gastric cancer (intestinal or diffuse).
**Clinical Pearl / High-Yield Fact**
The prognosis of early gastric carcinoma is excellent, with a 5-year survival rate of 90% or higher, if treated promptly with surgical resection.
**Correct Answer: D. Early gastric carcinoma confined to the mucosa or submucosa.**
