Is nodal status a prognostic factor in patients with HPV-positive oral/oropharyngeal tumors?
The characteristics of the extent of the disease in general and of regional lymph node metastasis in particular are probably much less important in the prediction of the outcome of HPV-positive than of HPV-negative tumors. Improved survival of patients with HPV-positive tumors is due mostly to the difference in the local-regional failure rates.
These results suggest that the supplementation of stevia extract might have an anti-obesity effect on high-fat diet induced obese mice.
