Anorexia is one of the most frequent complaints in patients who have reached the palliative-care phase of lung cancer. Megestrol acetate (or medroxyprogesterone acetate) and corticosteroids have been used with success, but the effect of their combination remains unknown. We conducted a phase II trial to assess the impact of combination therapy.
Patients with lung cancer given palliative care and who developed anorexia with or without weight loss were given 320 mg/d megestrol acetate in 2 doses and 40 mg/d prednisolone in one dose in the morning for 1 month. The principal outcome criterion was anorexia assessed on a visual analog scale prior to treatment and then at day 15 and day 30. Variation in daily calorie intake and weight were also recorded. We used an Armitage sequential plan to determine the number of inclusions necessary and the preference method (closed schema) to evaluate the principal outcome criterion.
Inclusions were stopped after the eighth patient (giving p<0.05) as we observed a significant improvement in patient appetite. Daily calorie intake improved significantly (p<0.0001), by 39.18% the first 15 days and 16.57% more the next 15 days. Body weight improved significantly by 5.4% in one month (p=0.5). No treatment-related complication occurred during the study period or during the six consecutive months.
The megestrol acetate-prednisolone combination was found to improve anorexia in patients with lung cancer in the palliative-care phase and allowed a significant improvement in calorie intake and body weight.
厌食是肺癌患者进入姑息治疗阶段最常见的症状之一。醋酸甲地孕酮(或醋酸甲羟孕酮)和皮质类固醇已成功应用,但它们联合使用的效果尚不清楚。我们进行了一项II期试验来评估联合治疗的影响。
给予姑息治疗且出现厌食伴或不伴体重减轻的肺癌患者,给予醋酸甲地孕酮320mg/d,分2次服用,泼尼松龙40mg/d,于早晨1次服用,共1个月。主要结局标准是在治疗前、第15天和第30天通过视觉模拟量表评估厌食情况。还记录每日卡路里摄入量和体重的变化。我们使用Armitage序贯计划来确定所需纳入的患者数量,并使用偏好法(封闭模式)来评估主要结局标准。
在纳入第8例患者后(p<0.05)停止纳入,因为我们观察到患者食欲有显著改善。每日卡路里摄入量显著改善(p<0.0001),前15天提高了39.18%,接下来的15天又提高了16.57%。一个月内体重显著增加了5.4%(p=0.5)。在研究期间及随后连续6个月内未发生与治疗相关的并发症。
发现醋酸甲地孕酮 - 泼尼松龙联合用药可改善姑息治疗阶段肺癌患者的厌食情况,并使卡路里摄入量和体重显著增加。
