摘要

背景甲羟孕酮和醋酸甲孕酮是人工合成的孕酮衍生物。孕激素是美国和一些欧洲国家批准的治疗癌症恶病质的药物。据描述,这些药物会增加食欲,导致体重增加。然而,对生存的影响仍然未知。本研究的目的是评价黄体酮对吉田肝癌AH-130大鼠癌症恶病质模型的生存、心功能、食欲和体重的影响。方法与结果本研究采用黄体酮对恶病质荷瘤大鼠的影响。大鼠分别每天给予0.5、5或50 mg/kg或安慰剂,从肿瘤接种后第1天开始,为期16天。在基线和第11天通过超声心动图分析心功能。在肿瘤接种前和第11天评估食物摄入量。在研究开始、研究结束或安乐死当天评估体重和身体组成。5 mg/kg/天显著提高生存率(风险比:0.48,95%可信区间:0.24-0.95,P = 0.0356)。然而,与安慰剂相比,孕激素治疗组在第11天的体重变化、身体组成以及食物摄入量方面没有显著差异。与安慰剂组相比,心功能也无显著差异。结论黄体酮提高了侵袭性肝癌恶病质模型大鼠的存活率,但对心功能、体重和食物摄入没有有益影响。生存获益的机制有待进一步研究阐明。

Progesterone improves survival in hepatoma cachexia rat model

Progesterone improves survival in hepatoma cachexia rat model
Medroxyprogesterone and megestrol acetate are synthetic progesterone derivatives. Progestagen is an approved drug for cancer cachexia in the USA and in some European countries. These agents have been described to increase appetite and to lead to weight gain. However, the effects on survival are still unknown. The aim of this study was to evaluate the effects of progesterone on survival, cardiac function, and appetite and body weight in the Yoshida hepatoma AH‐130 rat cancer cachexia model.
