When to use
- Prognostication and treatment planning (e.g. indwelling catheter vs pleurodesis) in malignant pleural effusion.
Formula
Sum of LDH (0-1), ECOG PS (0-3), neutrophil-to-lymphocyte ratio (0-1) and tumour type (0-2). Low 0-1, moderate 2-4, high 5-7.
Pearls and pitfalls
- High-risk patients have poor short-term survival and may be better served by definitive drainage than by pleurodesis.
