A adult presented with hematemesis and upper abdominal pain. Endoscopy reveals a growth at the pyloric antrum of the stomach. CT scan showed growth involving the pyloric antrum without infiltration or invasion into surrounding structures and no evidence of distant metastasis. At laparotomy neoplastic growth was observed to involve the posterior wall of stomach and the pancreas extending 6 cm up to tail of pancreas. What will be the most appropriate surgical management?

**Core Concept**
The case presents a patient with a neoplastic growth at the pyloric antrum of the stomach, extending to involve the posterior wall of the stomach and the pancreas. This scenario involves **gastric cancer** with potential **local invasion** into adjacent structures. The management of such cases depends on the extent of the tumor and its involvement with surrounding tissues.

**Why the Correct Answer is Right**
Given the tumor's location and extension into the pancreas without distant metastasis, a **curative resection** is feasible. The most appropriate surgical approach for a tumor involving the pyloric antrum and extending into the pancreas would be a **subtotal gastrectomy with distal pancreatectomy**, aiming to remove the tumor en bloc with clear margins. This approach is based on the principle of **oncologic surgery**, where the goal is to remove the tumor completely along with a margin of normal tissue to prevent recurrence.

**Why Each Wrong Option is Incorrect**
**Option A:** Would be incorrect if it suggested a less extensive procedure that might not achieve clear margins.
**Option B:** Might be incorrect if it proposed an even more extensive resection than necessary, potentially increasing morbidity without adding benefit.
**Option C:** Could be wrong if it recommended a palliative approach, which is not appropriate given the absence of distant metastasis.
**Option D:** Would be incorrect if it suggested a procedure that does not address the involvement of the pancreas.

**Clinical Pearl / High-Yield Fact**
In the management of gastric cancer, the extent of surgical resection is tailored to the tumor's location and spread. For tumors in the pyloric antrum with local invasion, achieving negative margins is crucial for improving survival rates.

**Correct Answer:** D. Subtotal gastrectomy with distal pancreatectomy.

✓ Correct Answer: C. Partial gastrectomy + distal pancreatectomy
