Abstract

Objectives

We prospectively investigated the roles of pretreatment dynamic contrast-enhanced MR imaging (DCE-MRI), diffusion-weighted MR imaging (DWI) and 18F-fluorodeoxyglucose-positron emission tomography (18F-FDG PET)/CT for predicting survival of oropharyngeal or hypopharyngeal squamous cell carcinoma (OHSCC) patients treated with chemoradiation.

Methods

Patients with histologically proven OHSCC and neck nodal metastases scheduled for chemoradiation were eligible. Clinical variables as well as DCE-MRI-, DWI- and 18F-FDG PET/CT-derived parameters of the primary tumours and metastatic neck nodes were analysed in relation to 3-year progression-free survival (PFS) and overall survival (OS) rates.

Results

Eighty-six patients were available for analysis. Multivariate analysis identified the efflux rate constant (K ep)-tumour < 3.79 min−1 (P = 0.001), relative volume of extracellular extravascular space (V e)-node < 0.23 (P = 0.004) and SUVmax-tumour > 19.44 (P = 0.025) as independent risk factors for both PFS and OS. A scoring system based upon the sum of each of the three imaging parameters allowed stratification of our patients into three groups (patients with 0/1 factor, patients with 2 factors and patients with 3 factors, respectively) with distinct PFS (3-year rates = 72 %, 38 % and 0 %, P < 0.0001) and OS (3-year rates = 81 %, 46 % and 20 %, P < 0.0001).

Conclusions

K ep-tumour, V e-node and SUVmax-tumour were independent prognosticators for OHSCC treated with chemoradiation. Their combination helped survival stratification.

Key Points

K ep -tumour, V e -node and SUV max -tumour are independent predictors of survival rates.
The combination of these three prognosticators may help stratification of survival.
MRI and FDG-PET/CT play complementary roles in prognostication of head and neck cancer.
