Eligibility
Inclusion criteria
Inclusion criteria: 1. Adult patients (20 years and older) undergoing elective craniotomy for primary or metastatic intracranial tumor resection. 2. Availability of complete preoperative laboratory panel: serum albumin, total protein (for globulin calculation), haemoglobin, WBC differential (lymphocytes), and platelet count , enabling calculation of all three biomarkers. 3. Cases of recurrent tumor requiring re-craniotomy are considered a new entry if the surgery occurs more than 90 days after the initial procedure.
Exclusion criteria
Exclusion criteria: Always excluded because these conditions chronically and independently dominate the study biomarkers: 1. Emergency craniotomy or trauma-related surgery 2. Severe anemia (Hb less than 8.0 g perdL preoperatively) dominates haemoglobin component of HALP 3. Active haemolytic disorder or thalassaemia major, intermedia 4. Haematologic malignancy, independently alters lymphocyte, platelet, and Hgb values 5. Decompensated liver disease (Child-Pugh B, C), severe albumin dysregulation independent of nutrition 6. Active systemic infection or sepsis at time of surgery 7. Advanced or uncontrolled HIV infection: CD4 count less than 200 cells per microL, AIDS-defining illness, or active opportunistic infection 8. Incomplete or missing critical EMR data (cannot compute primary biomarkers or primary outcome) 9. Re-craniotomy within 90 days of a prior procedure
