Child-Pugh score (effectiveness evaluation index)
Time Frame: At baseline, 3, 7 and 21 days after the first administration, 21 days after the second administration (if any), and 1, 3, 6 and 12 months after the last administration.
|
The Child-Pugh grading standard is a grading standard commonly used in clinical practice to quantitatively evaluate the liver reserve function of patients with liver cirrhosis. Grading: 5~6 points for Grade A, 7~9 points for Grade B and 10~15 points for grade C; Note: For Primary Biliary Cirrhosis (PBC) or Primary Sclerosing Cholangitis (PSC): total bilirubin (umol/L): 17~68 is 1 point, 68~170 is 1 point, and >170 is 1 point; The Child-Pugh grading standard has been widely recognized by clinicians, and provides a specific clinical reference for the selection of treatment options for patients with liver cirrhosis and has important clinical value. |
At baseline, 3, 7 and 21 days after the first administration, 21 days after the second administration (if any), and 1, 3, 6 and 12 months after the last administration.

The Model for End-Stage Liver Disease (MELD) score (effectiveness evaluation index)
Time Frame: Baseline, 3, 7, and 21 days after the first administration, 21 days after the second administration (if any), and 1, 3, 6, and 12 months after the last administration.
|
MELD is a numerical scale, ranging from 6 (less ill) to 40 (gravely ill), used for liver transplant candidates age 12 and older. It gives each person a 'score' (number) based on how urgently he or she needs a liver transplant within the next three months. The number is calculated by a formula using three routine lab test results: MELD score = 3.8×ln[bilirubin (mg/dl)] + 11.2×ln(INR) + 9.6×ln[Scr(mg/dl)] + 6.4×(Cause: Bile or alcoholic 0, other 1) Bilirubin (mg/dl) = Bilirubin (μmol/L)/17.1 Scr(mg/dl) = Scr(μmol/L)/88.4 |
Baseline, 3, 7, and 21 days after the first administration, 21 days after the second administration (if any), and 1, 3, 6, and 12 months after the last administration.
|
KPS score (effectiveness evaluation index)
Time Frame: Baseline, 3, 7, and 21 days after the first administration, 21 days after the second administration (if any), and 1, 3, 6, and 12 months after the last administration.
|
KPS score is the Karnofsky (Karen, KPS, percentile method) functional status scoring standard. The higher the score, the better the health status, and the more the patient able to tolerate the side effects of treatment, hence a better curative effect. It is generally believed that a Karnofsky score above 80 is independent, which means the patient is able to take care of himself. Karnofsky score between 50 to 70 stands for a semi-independent status, that is, the patient is semi-self-care. A score of 50 means the patients require help from others. Those with a score greater than 80 are in better postoperative state and have a longer survival period. The lower the score, the worse the health status. If the score is less than 60, many effective anti-tumor treatments cannot be implemented. |
