True about Gastric carcinoma are all, except:a) Haemetemesis present in majority of patientsb) H. Pylori association is presentc) D2 gastrectomy includes total gastrectomyd) Surgical non-curative lesions should not be resectede) Patients after total gastrectomy should be given vitamin B12

**Core Concept**
Gastric carcinoma, also known as stomach cancer, is a malignant tumor that arises from the lining of the stomach. The underlying pharmacological and physiological principles being tested include the clinical presentation, risk factors, and management of gastric carcinoma.

**Why the Correct Answer is Right**
The correct answer is related to the clinical presentation and management of gastric carcinoma. Haemetemesis, or vomiting blood, is not typically present in the majority of patients with gastric carcinoma, as the disease often presents with non-specific symptoms such as weight loss and abdominal pain. H. Pylori association is a known risk factor for gastric carcinoma. D2 gastrectomy, which includes total gastrectomy, is a surgical procedure used to treat gastric carcinoma. Patients who undergo total gastrectomy require lifelong vitamin B12 supplementation.

**Why Each Wrong Option is Incorrect**
**Option A:** Haemetemesis is not typically present in the majority of patients with gastric carcinoma, making this statement incorrect.
**Option D:** Surgical resection is sometimes performed for non-curative lesions to alleviate symptoms and improve quality of life.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that patients who undergo total gastrectomy require lifelong vitamin B12 supplementation to prevent deficiency. H. Pylori infection is a significant risk factor for gastric carcinoma.

**Correct Answer:** D. Surgical non-curative lesions should not be resected
