Clinical Studies on the Treatment of Cancer Cachexia with Megestrol Acetate plus Thalidomide

Background: The management of cancer-related anorexia/cachexia syndrome (CACS) is a great challenge in clinical practice. To date, practice guidelines for the prevention and treatment of CACS are lacking. The authors conducted a randomized study to confirm the effectiveness and safety of treatment of CACS utilizing megestrol acetate (MA) plus thalidomide. Methods: One hundred and two candidates with CACS were randomly assigned to two treatment groups (trial group and control group): the trial group received MA (160 mg po, bid) plus thalidomide (50 mg po, bid), while the control group received MA (160 mg po, bid) alone. Treatment duration was 8 weeks. Results: Analysis of the trial group demonstrated a significant increase from baseline in body weight (Conclusion: A combination regimen of MA and thalidomide is more effective than MA alone in the treatment of CACS.
