Follow-up
BLOOD, BONE METASTASES
The same evaluation protocol was used. Blood tests, such as routine blood and liver function tests, were performed before and after each cycle of S1-MT, and were simultaneously performed at each imaging evaluation for non-MT patients. Computed tomography (CT) and/or magnetic resonance imaging (MRI) were performed every 3 months for efficacy evaluation. CT was used to evaluate the lung and abdomen. MRI was used to evaluate the nasopharynx and bone, and emission computed tomography (ECT) was used to identify bone metastases if necessary.
