Spontaneous rosette-forming lymphocyte sensitivity to prostaglandins in patients with cervical carcinoma after surgery.

Abstract We have reported a marked decrease of lymphocyte sensitivity to prostaglandins (PGs) in patients with untreated cervical carcinoma and other solid neoplasias. Particularly, Ea and ME rosette formation was inhibited only slightly by PGs in all cancer patients studied, as compared with the high inhibition values observed in normal individuals (Clin Immunol Immunopathol, 1981). In the present work, the PG-induced inhibition of Ea and ME rosette formation has been studied in patients with stage 0 cervical carcinoma up to 180 days after hysterectomy. It has been found that in these patients the PG sensitivity increased gradually up to or higher than the levels seen in normal control subjects. However, the PG sensitivity of Ea is restored earlier after surgery, while ME show a delayed recovery. Since the PG sensitivities correlate well with the clinical status of patients, it is suggested that such sensitivity may represent a useful test for following patients with cervical carcinoma.
