Mesothelioma CALGB Score

The CALGB prognostic score for malignant pleural mesothelioma uses distinct clinical variables compared to EORTC, including pleural LDH, platelets, chest pain, and age.

Evidence-based context for fast calculator use

Purpose:
CALGB Mesothelioma Score stratifies malignant pleural mesothelioma prognosis to guide treatment intensity and clinical trial eligibility.
Population:
patients undergoing thoracic oncology risk, staging, or nodule assessment
Factors:
ECOG Performance Status, Age > 75?, Histology, Chest Pain Present?, Serum LDH > 500 IU/L?, Platelets > 400k?
Reference:
Herndon JE, et al. Factors predictive of survival among 337 patients with mesothelioma treated with chemotherapy at Cancer and Leukemia Group B institutions. Chest. 1998;113(3):723-731.

Mesothelioma CALGB Score

Clinical Context & Background

The CALGB prognostic score for malignant pleural mesothelioma uses distinct clinical variables compared to EORTC, including pleural LDH, platelets, chest pain, and age. It stratifies patients into six prognostic subgroups.

When To Use

  • Use Mesothelioma CALGB Score when cALGB Mesothelioma Score stratifies malignant pleural mesothelioma prognosis to guide treatment intensity and clinical trial eligibility.
  • Confirm that the patient, diagnosis, disease phase, and available inputs match the cited model before calculation.

How To Interpret

  • Interpret the displayed result using the calculator-specific formula and reference table, spanning Group 1 through Group 5 - 6.
  • A boundary result should prompt input verification and clinical review rather than false precision.

What To Do Next

  • Confirm whether the clinical question is screening eligibility, nodule malignancy, staging, or treatment prognosis and move to the corresponding thoracic pathway.
  • Document the inputs, result, timing, and clinical context so the assessment can be reproduced.

Limitations

  • Lung screening, nodule probability, radiology classification, and cancer staging tools answer different questions.
  • The result supports clinician judgment and does not independently determine treatment.

Validated Population

patients undergoing thoracic oncology risk, staging, or nodule assessment

How to apply this result

For a representative case, verify ECOG Performance Status, Age > 75?, Histology, calculate the result, and confirm that its classification matches the highlighted reference band before continuing the disease-specific pathway.
