As immunological parameters in patients with head and neck cancer, the authors adopted the following simple, comvenient, repeatable and routinely-usable figures for the treatment of head and neck cancer:
1) In vitro PPD
2) The rate of active E rosette formation
The figures are considered useful as parameters for the purpose, since some changes were observed at terminal stages of carcinoma.
