Abstract
Background
Chemoradiotherapy (CRT) is used to treat cervical lymph node(s) metastatic head and neck cancer patients. Evaluation and treatment of lymph node(s) after CRT is important to improve the prognosis.
Methods
Prior to CRT, we determined the TNM stage by visual and imaging examinations. Metabolic tumor volume (MTV) and total lesion glycolysis (TLG) were calculated from the results of fluorodeoxyglucose-positron emission tomography (FDG-PET). After CRT, the patients were divided in two groups—complete response (CR) and non-CR—and their responses were compared with the clinical characteristics.
Results
T4, N2b, N2c and TLG2.5 ≥18.8 were statistically significant predictive indices before CRT. The odds ratio, 95 % confidence interval and p value were, respectively—T4: 2.73, 1.15–6.51, 0.0230; N2b: 6.96, 1.50–32.3, 0.0132; N2c: 11.80, 2.37–58.50, 0.00258; and TLG2.5 ≥18.8: 6.25, 2.17–18.00, 0.000672.
Conclusions
TLG was found to be a good predictive factor for metastatic lymph node(s) prior to CRT treatment. After CRT treatment, FDG-PET was found to be highly specific and useful for negative screening.
