Martin et al developed a grid for classifying cancer-associated weight loss. The higher the grade of weight loss the worse the prognosis. The authors are from multiple institutions in Canada and Europe.
Patient selection: cancer-associated weight loss
Parameters:
(1) body mass index (BMI) in kg per square meter
