The prognostic nutritional index (PNI) is an integrated parameter consisting of serum albumin and lymphocyte count. Immunonutritional status defined in this manner is well-known to be closely linked to the prognosis of several other cancers.

Morphological Asymmetry of Pelvic Rings: A Study Based on Three-Dimensional Deviation Analysis.
