If TTP is delayed significantly (dTTP > or =3.2 s), the FAIR with intermediate or short TI showed underestimation of perfusion in the same area with delay in TTP.

UNLABELLED: High tumor uptake of (18)F-FDG is associated with an unfavorable outcome in cancer patients. We evaluated pretreatment (18)F-FDG uptake as guidance for the primary treatment modality in patients with squamous cell carcinoma (SCC) of the oropharynx. METHODS: Fifty-two consecutive patients with newly diagnosed resectable SCC of the oropharynx underwent (18)F-FDG PET before treatment. Primary treatment modalities consisted of surgical resection plus radiotherapy (RT) (surgery group, n=3

OBJECTIVES: Lymph node (LN) metastasis of oral cavity squamous cell carcinoma (OSCC) is associated with survival outcomes. However, the relationship between different metastatic nodal factors and treatment outcomes requires further elucidation. This study examined nodal factors predictive of recurrence and survival in patients with OSCC. METHODS: This prospective observational study included 157 patients with OSCC who underwent surgery between 2010 and 2015. Clinicopathological and follow-up inf

OBJECTIVES: Recurrence in the late post-treatment period is relatively common in salivary gland cancer (SGC), but risk factors and survival associated with late recurrence have been rarely studied. We investigated the incidence and risk factors of SGC recurrence >5 years after treatment and associated survival. DESIGN: A retrospective cohort study. SETTING: University hospital. PARTICIPANTS: A total of 240 patients with previously untreated SGC who underwent definitive treatment. MAIN OUTCOME ME

OBJECTIVES: Due to relatively high (18) F-fluorodeoxyglucose accumulation in the tonsillar region, the detection of occult tonsillar cancers by (18) F-fluorodeoxyglucose positron emission tomography/computerised tomography remains controversial. Therefore, we assessed the usefulness of quantitative tonsil (18) F-fluorodeoxyglucose uptake in identifying occult tonsillar squamous cell carcinoma. DESIGN: A case-control study of retrospective cohorts. SETTING: University Teaching Hospital. MAIN OUTC

OBJECTIVES: Cervical lymph node metastases from an unknown primary tumour are a heterogeneous disease entity with various clinical features. There are many controversies regarding treatment methods and treatment response predictions. Therefore, we examined the prognostic significance of biomarkers in patients with cervical metastasis of unknown primary tumour. DESIGN: A molecular study of retrospective cohorts. SETTING: University teaching hospital. MAIN OUTCOME MEASURES: Metastatic cervical lym

BACKGROUND: Next-generation sequencing (NGS) has become widely available but molecular profiling-guided therapy (MGT) had not been well established in the real world due to lack of available therapies and expertise to match treatment. Our study was designed to test the feasibility of a nationwide platform of NGS-guided MGT recommended by a central molecular tumor board (cMTB) for metastatic solid tumors. PATIENTS AND METHODS: Patients with advanced or metastatic solid tumors with available NGS r
