den Exter et al developed a score for determining the risk of 30-day mortality in a patient with acute pulmonary embolism and active cancer. This can help to identify a patient who may benefit from more aggressive management. The authors are from multiple institutions in Spain participating in the Reigistro Informatizado de la Enfermedad TromboEmbolica (RIETE) Study.
Patient selection: acute pulmonary embolism and active cancer
Outcome: 30-day mortality
Parameters:
(1) metastases
(2) immobilization
(3) age in years
(4) heart rate in beats per minute
(5) systolic blood pressure in mm Hg
(6) body weight in kilograms

total score =
= SUM(points for all 6 parameters)
Interpretation:
• minimum score: 0
• maximum score: 10
• The higher the score the greater the risk of short-term mortality.

Additional laboratory findings associated with a poor prognosis:
(1) creatinine clearance < 30 mL per minute
(2) white blood cell count > 11,000 per µL
Performance:
• The area under the ROC curve is 0.76.
