Orosomucoid: Prealbumin ratio—a marker of the host-tumor relationship in head and neck cancer

Abstract The OPR was studied in 203 patients with squamous cell carcinoma of the head and neck at the time of diagnosis, before any specific treatment. The mean initial OPR value was significantly higher in cancer patients than in 63 healthy controls: 5.29 ± 3.09 vs. 2.63 ± 1.07 ; P 5.10 ± 3.85 vs. 3.23 ± 1.99 , P 2 years, 51% of patients with an OPR 6 were alive vs. only 24.5% of those with an OPR > 6 , P 16 months vs. 7 months, P 89 of the patient who received chemotherapy (mean survival 16 months vs. 6 months, P 2 years.
