To analyse the relationship between histology of head and neck cancers and maximum standardized uptake value (SUVmax) and metabolic tumor volume (MTV).
METHODS
Positron-emission tomography (PET)/computed tomography (CT) examinations of patients with head
and neck squamous cell carcinoma (SCC) and non-squamous cell carcinoma (non-SCC) tumors with
52 patients reviewed from 2007 to 2019 retrospectively. MTV and SUVmax values of primary tumor
were measured in PET/CT and both groups were statistically compared.
RESULTS
The median SUVmax value was 17.88 (3?52) and MTV was 5.40 (0-329). No significant difference was
established between the groups in terms of age, gender and MTV (p=0.948, p=0.166 and p=0.189) respectively.
SUVmax value in SCC group was significantly higher (p=0.003) than the non-SCC group.
CONCLUSION
Head and neck squamous cell carcinomas (HNSCC) have higher SUVmax values than non SCC tumors.
No significant difference was established between the groups in terms of MTV.
