Patient selection: hypopharynx cancer
Parameters:
(1) location in the pyriform sinus
(2) T status
(3) N status
(4) ACE27 score
(5) body mass index (BMI) in kg per square meter, from 10 to 45
(6) hemoglobin in mmol/L, from 4 to 11.5 (use conversion factor 0.6206 for g/dL to mmol/L)
(7) serum albumin in g/L, from 15 to 60
(8) leukocytosis (WBC >= 10.5 * 10^9/L)
points for BMI =
= 67.076 - (1.49 * (BMI))
points for hemoglobin =
= 100.58 - (8.746 * (hemoglobin))
points for serum albumin =
= 133.333 - (2.222 * (albumin))
