简要总结
RATIONALE: Diagnostic procedures, such as fludeoxyglucose F 18-PET/CT scan, may help doctors find head and neck cancer and find out how far the disease has spread. It may also help doctors plan the best treatment.
PURPOSE: This phase II trial is studying fludeoxyglucose F 18-PET/CT imaging to see how well it works in assessing the tumor and planning neck surgery in patients with newly diagnosed head and neck cancer.
详细描述
OBJECTIVES:
Primary
- Determine the negative predictive value of PET/CT imaging based upon pathologic sampling of the neck lymph nodes in patients with head and neck cancer planning to undergo N0 neck surgery.
- Determine the potential of PET/CT imaging to change treatment.
Secondary
- Estimate the sensitivity and diagnostic yield of PET/CT imaging for detecting occult metastasis in the clinical N0 neck (both by neck and lymph node regions) or other local sites.
- Determine the effect of other factors (e.g., tumor size, location, secondary primary tumors, or intensity of FDG uptake) that can lead to identification of subsets of patients that could potentially forego neck dissection or that can provide preliminary data for subsequent studies.
- Compare the cost-effectiveness of using PET/CT imaging for staging head and neck cancer vs current good clinical practices.
- Evaluate the incidence of occult distant body metastasis discovered by whole-body PET/CT imaging.
- Correlate PET/CT imaging findings with CT/MRI findings and biomarker results.
- Evaluate the quality of life of these patients, particularly of those patients whose management could have been altered by imaging results.
- Evaluate PET/CT imaging and biomarker data for complementary contributions to metastatic disease prediction.
- Compare baseline PET/CT imaging and biomarker data with 2-year follow up as an adjunct assessment of their prediction of recurrence, disease-free survival, and overall survival.
- Determine the proportion of neck dissections that are extended (i.e., additional levels that clinicians intend to dissect beyond the initial surgery plan) based on local-reader PET/CT imaging findings shared with the surgeon before dissection.
- Estimate the optimum cutoff value of standardized uptake values for diagnostic accuracy of PET/CT imaging.
- Evaluate the impact of PET/CT imaging on the N0 neck across different tumor subsites (defined by anatomic location).

主要结局
Negative predictive value of PET/CT imaging for staging the N0 neck based upon pathologic sampling of the neck lymph nodes
时间窗: Within Two Weeks Before Surgery and after sampling of neck lymph nodes
True negative cases will be determined by histopathology reports. The test will be defined as positive when SUVmax value of ≥ 2.0; and negative otherwise.
