**Core Concept**
The management of carcinoid tumors involves a multidisciplinary approach, taking into account the tumor's size, location, and potential for metastasis. The goal is to determine the optimal treatment strategy, which may include surgical resection, chemotherapy, or targeted therapy.

**Why the Correct Answer is Right**
For carcinoid tumors less than 2 cm in size, simple resection is often sufficient. However, for tumors larger than 2 cm, such as in this case, a more aggressive approach is warranted. The correct answer involves a comprehensive evaluation, including imaging studies and endocrine function tests, to determine the extent of disease and potential for metastasis. This will guide the decision for surgical resection, which may involve a right hemicolectomy or other procedures.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not involve a comprehensive evaluation, which is crucial in managing carcinoid tumors. A simple resection may not be sufficient for tumors larger than 2 cm.
**Option B:** This option is incorrect as it may not be necessary to perform a lymph node dissection for all patients with carcinoid tumors. The decision for lymphadenectomy should be based on the tumor's size, location, and potential for metastasis.
**Option C:** This option is incorrect as it does not involve a thorough assessment of the patient's symptoms and potential for metastasis. A comprehensive evaluation is essential in determining the optimal treatment strategy.

**Clinical Pearl / High-Yield Fact**
For carcinoid tumors, the 5-year survival rate is inversely correlated with tumor size, with 5-year survival rates of 95% for tumors less than 1 cm, 50-60% for tumors 1-2 cm, and less than 20% for tumors larger than 2 cm.

**Correct Answer:** B.
