Mean vectors of H and NC group vs. the control group were characterized by an increased normalized resistance component with a reduced reactance component (separate 95% confidence limits, P<0.05), indicating a decreased ionic conduction (dehydration) with loss of dielectric mass (cell membranes and tissue interfaces) of soft tissue. |

Patients with a phase angle ≤ 5° had significantly lower nutritional and functional status, impaired quality of life (P lt 0.0001), and increased mortality (P lt 0.001). |

The present study demonstrates that PA, used as SPA, is an independent prognostic indicator. Patients with PA < -1.65° still presented a higher mortality rate (RR 2.35 CI: 1.41-3.90; p = 0.001). |

Phase angle =0.384, P=0.024) was found to be strictly related to survival time and can be therefore considered a prognostic tool in patients with advanced cancer. |

Weight loss was associated with shorter survival. A higher phase angle (PA) on day 1 predicted longer survival. Increased PA during hydration predicted shorter survival: increased weight during hydration predicted longer survival. An increase in phase angle during hydration predicted poorer survival and preexisting intracellular dehydration, cachexia, or poor membrane function. |

Patients with phase angle ≤ 5.3° had a median survival of 7.6 months (95% CI: 4.7 to 9.5; n = 81), while those with > 5.3° had 12.4 months (95% CI: 10.5 to 18.7; n = 84); (p = 0.02). Every one degree increase in phase angle was associated with a relative risk of 0.79 (95% CI: 0.64 to 0.97, P = 0.02).
N.P. Nutritional interventions targeted at improving phase angle could potentially lead to an improved survival in patients with advanced non-small cell lung cancer (advanced NSCLC). |
