Does low serum level of hepatitis B core-related antigen indicate unlikely reactivation of hepatitis after cessation of lamivudine therapy?
HBcrAg can be a useful marker to identify patients who are not at risk of reactivation of severe hepatitis after discontinuation of lamivudine administration.
The initial tumor size is closely related to histologic response and is an important prognostic factor in osteosarcoma. Tumor size is best represented by AJCC stage and RTP. These parameters may serve as a basis for risk-adapted therapy in combined stratification with histologic response.
