Abstract

Objective: To measure and compare pre- and post-treatment levels of serum total glutathione-S-transferase (GST) in stage IV cervical cancer patients and erythrocytic glutathione (GSH) and malondialdehyde (MDA) and plasma ceruloplasmin (CP) and total GST in stage IV oral cancer patients and to correlate with the response to treatment during a two year follow-up period in respective cancer groups. Methods: Thirty-four biopsy-proven stage IV oral cancer and cervical cancer patients (n=17 in each group) who underwent same mode of treatment were chosen for this study. Erythrocytic MDA and GSH, CP and serum total GST were measured in all patients before the onset of treatment, and the GST level was only measured in cervical cancer patients after radiotherapy. The levels were compared with their respective prognosis in 2 years. Results: Oral cancer patients with higher pretreatment levels of GSH, CP and GST came with cancer recurrence within 2 years after the onset of treatment. Cervical cancer patients with higher post radiotherapy levels of serum total GST had higher recurrence tate. Conclusions: This study indicates there may be a role for these antioxidant parameters namely GST, GSH, CP in assessment of long term survival and prognosis of cancer patients.
