Prevost et al identified a number of predictors for mortality in a patient with a non-small cell lung cancer (NSCLC). Hypermetabolism of the bone marrow as detected by 18F-FDG PET scan was associated with increased mortality. The authors are from Universitaire de Sherbrooke and Universitaire de Montreal in Quebec, Canada.
Patient selection: non-small cell lung cancer, excluding those with recurrent or metastatic disease
Patient assessment: complete blood count (CBC) and 18F-FDG PET scan
Parameters associated with mortality from the multivariate analysis:
(1) bone marrow metabolism on PET scan (based on SUV)
(2) nodal stage on the PET scan
(3) hemoglobin
(4) platelet count
(5) white blood cell count

where:
• A patient with N0 or N1 is a potential candidate for surgical resection. People who underwent surgical resection had a better survival.
number of findings associated with a worse prognosis =
= SUM(points for all 5 parameters)
Interpretation:
• minimum score: 0
• maximum score: 5
• The higher the score the shorter the survival.
