[2025-09-25T11:26:43.376172] [PI reasoning] **Examining radiation therapy**

I’m considering the historical context around radiation therapy, especially in relation to neck dissection. Many centers seem to prefer performing neck dissection either before or after radiation, and while it may not improve survival, it could aid in control. There seems to be some controversy around this, so I think it’s important to gather more evidence to get a clearer picture. Let's see what I can uncover!

[2025-09-25T11:27:02.138484] [PI reasoning] **Reviewing findings on neck dissection**

I’m reviewing the conclusion that radiotherapy is effective for the neck. It seems there's some debate about whether neck dissection is necessary, especially for early nodal stages. Data indicates there’s no significant difference between patients with only a biopsy versus those with neck dissection, suggesting dissection may not be required. The answer appears to be "no." I’ll confirm this with the abstract and then craft the final answer along with an explanation and citations.
