[Immunglobulins in serum of laryngeal and pharyngeal cancer patients (author's transl)].

The majority of our laryngeal and pharyngeal cancer patients had increased serum immunoglobulin values, which normalised in nearly all of the patients examined six month after successful surgical treatment. The decreased values of the serum immunoglobulins were found in patients with advanced tumours as well as in those with T1 and T2 tumours. Some of these latter patients also had a deficient cellular immune response, and it is likely that a combined immune deficiency was the leading factor which caused the malignancy in those patients.
