Randomized Controlled Trial Comparative Study Clinical TrialProspective randomised trial of two dose levels of megestrol acetate in the management of anorexia-cachexia syndrome in patients with metastatic cancer.
Two doses of megestrol acetate (MA) have been prospectively compared in a random fashion as treatment for cancer-related anorexia-cachexia syndrome (ACS) in 122 patients with progressive soft tissue sarcoma, colorectal, lung, head and neck and renal cancer resistant to systemic chemotherapy. After 30 days of MA, 55% of patients receiving MA at 160 mg day-1 reported an increase in appetite, 27% of patients no variation and 18% complained of a decrease in appetite. Patients treated with MA at 320 mg day-1 reported an increase in appetite in 68% of cases, a stabilisation in 20% of cases and a decrease in 12%. ⋯ In conclusion, the data achieved in the present study confirm the clinical safety and effectiveness of oral MA in the management of ACS in patients with advanced cancer resistant to systemic chemotherapy. Moreover, data concerning the dose escalation of MA dosage in unresponsive patients suggest that a step by step increase in MA dosage could be the best way of administering MA for the management of ACS and that the increase of MA dosage over 480 mg day-1 will probably be useless in the vast majority of cases. Data on body weight suggest that after 2 weeks' therapy MA could be stopped or its dosage tailored to patients' needs since the majority of patients respond after only 15 days of MA.
