Pre-treatment metabolic tumor volume predicts tumor metastasis and progression in high-grade salivary gland carcinoma.

Purpose: High-grade salivary gland carcinoma (SGC) shows a high rate of metastasis and post-treatment recurrence, resulting in poor patient survival. Therefore, we evaluated the utility of pre-treatment F-FDG PET/CT parameters in predicting metastasis, tumor progression, and survival of high-grade SGC patients.

Methods: This observational study included 75 patients with previously untreated high-grade SGC who underwent pre-treatment F-FDG PET/CT scanning and subsequent treatment.

Prediction of distant metastasis and survival in adenoid cystic carcinoma using quantitative F-FDG PET/CT measurements.

Objectives: Adenoid cystic carcinoma (AdCC) in the salivary gland shows a high rate of distant metastasis, which is related to the resulting poor prognosis. We therefore examined the role of pretreatment F-FDG PET/CT for prediction of distant metastasis, recurrence/progression, and survival in AdCC.

Methods: This study included 52 patients who underwent pretreatment F-FDG PET/CT scanning and subsequent treatments for AdCC.

Pretreatment albumin level predicts survival in head and neck squamous cell carcinoma.

Objectives/hypothesis: Poor nutritional status in patients with head and neck squamous cell carcinoma (HNSCC) is associated with tumor progression and survival. This study examined the prognostic value of nutritional and hematological markers in patients with HNSCC who received definitive treatments.

Study Design: A prospective observational cohort study.

Simultaneous versus Sequential Intratympanic Steroid Treatment for Severe-to-Profound Sudden Sensorineural Hearing Loss.

Objectives: Severe-to-profound sudden sensorineural hearing loss (SSNHL) has a poor prognosis. We aimed to compare the efficacy of simultaneous and sequential oral and intratympanic steroids for this condition.

Methods: Fifty patients with severe-to-profound SSNHL (>70 dB HL) were included from 7 centers.
