BACKGROUND Surgical resection of prolactinomas resistant to dopamine agonists is frequently incomplete due to fibrotic changes of the tumour under pharmacological therapy. In order to identify a subgroup of patients who may benefit from early surgery, we thought to investigate possible predictive factors of pharmacological resistance of prolactinomas to dopamine agonists. METHODS We retrospectively analyzed a database of a Belgian tertiary reference center for patients with pituitary tumours from 2014 to 2016. The groups of interest were patients with dopamine agonist responsive and resistant prolactinomas. The possible predictive factors, including MRI findings, endocrinological parameters, response of tumour and patient factors for dopamine agonist resistance were investigated. RESULTS We included 69 patients of whom 52 were women (75,4%) and 17 were men (24,6%). Rate of dopamine agonist resistance was 15.9%. We identified four significant predictors of dopamine agonist resistance: male gender, a large tumour volume, prolonged time to prolactin normalization and presence of a cystic, hemorrhagic and/or necrotic component. In addition, symptoms due to mass effect, high baseline prolactin level and a high contrast capture on MRI are factors that can be taken into consideration. CONCLUSION We identified predictive factors for pharmacological resistance and developed a scoring system for patient specific prediction of resistance to dopamine agonists. This scoring system may have impact on the timing and decision of surgery in prolactinoma patients after further prospective evaluation.

催乳素瘤患者多巴胺激动剂抵抗的预测指标。

背景技术由于在药物治疗下肿瘤的纤维化变化,对多巴胺激动剂有抵抗力的泌乳素瘤的手术切除常常是不完全的。为了确定可能从早期手术中受益的患者亚组,我们认为研究催乳素瘤对多巴胺激动剂的药理抗药性的可能预测因素。方法我们回顾性分析了2014年至2016年比利时三级参考中心垂体瘤患者的数据库。感兴趣的人群是多巴胺激动剂反应性和耐药性泌乳素瘤患者。研究了可能的预测因素,包括MRI表现,内分泌学参数,肿瘤反应和多巴胺激动剂耐药性的患者因素。结果我们纳入了69位患者,其中52位是女性(75位,4%)和17名男性(24.6%)。多巴胺激动剂的抵抗率为15.9%。我们确定了多巴胺激动剂耐药性的四个重要预测指标:男性,大量肿瘤,催乳素正常化时间延长以及囊性,出血性和/或坏死性成分的存在。此外,由于质量效应,基线泌乳素水平高和MRI造影剂捕获率高引起的症状是可以考虑的因素。结论我们确定了药理学抗药性的预测因素,并开发了一个针对患者对多巴胺激动剂抗药性具体预测的评分系统。经过进一步的前瞻性评估后,该评分系统可能会对泌乳素瘤患者的手术时机和决策产生影响。我们确定了多巴胺激动剂抗药性的四个重要预测指标:男性,大量肿瘤,催乳素正常化时间延长以及囊性,出血性和/或坏死性成分的存在。另外,可以考虑的因素包括质量效应,基线泌乳素水平高和MRI造影剂捕获率高。结论我们确定了药理学抗药性的预测因素,并开发了一个针对患者对多巴胺激动剂抗药性具体预测的评分系统。经过进一步的前瞻性评估后,该评分系统可能会对泌乳素瘤患者的手术时机和决策产生影响。我们确定了多巴胺激动剂抗药性的四个重要预测指标:男性,大量肿瘤,催乳素正常化时间延长以及囊性,出血性和/或坏死性成分的存在。此外,由于质量效应,基线泌乳素水平高和MRI造影剂捕获率高引起的症状是可以考虑的因素。结论我们确定了药理学抗药性的预测因素,并开发了一个针对患者对多巴胺激动剂抗药性具体预测的评分系统。经过进一步的前瞻性评估后,该评分系统可能会对泌乳素瘤患者的手术时机和决策产生影响。出血和/或坏死成分。此外,由于质量效应,基线泌乳素水平高和MRI造影剂捕获率高引起的症状是可以考虑的因素。结论我们确定了药理学抗药性的预测因素,并开发了一个针对患者对多巴胺激动剂抗药性具体预测的评分系统。经过进一步的前瞻性评估后,该评分系统可能会对泌乳素瘤患者的手术时机和决策产生影响。出血和/或坏死成分。此外,由于质量效应,基线泌乳素水平高和MRI造影剂捕获率高引起的症状是可以考虑的因素。结论我们确定了药理学抗药性的预测因素,并开发了一个针对患者对多巴胺激动剂抗药性具体预测的评分系统。经过进一步的前瞻性评估后,该评分系统可能会对泌乳素瘤患者的手术时机和决策产生影响。
