Controversy exists as to the criteria for selecting patients with carcinoma of the tonsil for treatment with ipsilateral radiotherapy (RT).
The American College of Radiology (ACR) Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current literature from peer reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of treatment procedures by the panel. In those instances where evidence is not definitive, expert opinion may be used to recommend treatment.
The ACR Expert Panel on Radiation Oncology - Head and Neck Cancer developed consensus recommendations for selecting patients with tonsillar carcinoma for ipsilateral RT.
Patients that are appropriate for ipsilateral RT have less than 1 cm of tumor invasion into the soft palate or base of tongue, and nodal stage of N0 to 1.
对于选择接受同侧放射治疗（RT）的扁桃体癌患者，存在争议。
美国放射学院（ACR）适宜性标准是针对特定临床情况的循证指南，每 2 年由多学科专家小组进行审查。指南的制定和审查包括对同行评议期刊的现有文献进行广泛分析，并应用成熟的共识方法（改良 Delphi 法）对小组治疗程序的适宜性进行评分。在证据不明确的情况下，专家意见可用于推荐治疗。
ACR 放射肿瘤学-头颈部癌症专家组就选择扁桃体癌患者进行同侧 RT 达成了共识建议。
适合同侧 RT 的患者肿瘤侵犯软腭或舌根小于 1cm，且淋巴结分期为 N0 至 1。
