摘要
赛乐替尼是一种选择性RET激酶抑制剂,在治疗伴有RET改变的晚期甲状腺髓样癌和分化型甲状腺癌患者方面疗效显著。对赛铂替尼产生原发性耐药的情况非常少见,其潜在机制也鲜为人知。我们报告了一例42岁女性晚期MTC患者的病例,该患者携带体细胞M918T RET突变,对舍铂卡尼产生了原发性耐药。尽管在确诊病情进展后及时开始了治疗,但患者的病情仍在迅速扩散,表现为出现新的转移病灶和肿瘤负荷增加。基因组分析未发现与靶上或靶下耐药相关的其他突变。该病例凸显了晚期 MTC 对赛铂替尼产生原发性耐药的罕见临床情况。虽然继发性耐药机制已被充分证实,但对原发性耐药机制的了解仍然很少。可能的原因包括肿瘤异质性和替代信号通路的激活,这些仍有待阐明。针对耐药机制的新兴疗法和下一代 RET 抑制剂为进一步研究提供了前景广阔的途径。
Primary resistance to selpercatinib in a patient with advanced medullary thyroid cancer.
Selpercatinib, a selective RET kinase inhibitor, has demonstrated remarkable efficacy in treating patients with advanced medullary (MTC) and differentiated thyroid cancer with RET alterations. Primary resistance to selpercatinib is a very uncommon situation, and its underlying mechanisms are poorly understood. We report the case of a 42-year-old female with advanced MTC harboring a somatic M918T RET mutation who exhibited a primary resistance to selpercatinib. Despite prompt treatment initiation after the diagnosis of progressive disease, the patient continued experiencing rapid spread of disease, characterized by the appearance of new metastatic lesions and increased tumor burden. Genomic analysis revealed no additional mutations associated with on-target or off-target resistance. This case highlights a rare clinical scenario of primary resistance to selpercatinib in advanced MTC. While secondary resistance mechanisms have been well-documented, primary resistance remains poorly understood. Possible explanations include tumor heterogeneity and activation of alternative signaling pathways that stills need to be elucidated. Emerging therapies targeting resistance mechanisms and next-generation RET inhibitors offer promising avenues for further investigation.
期刊介绍:
Well-established as a major journal in today’s rapidly advancing experimental and clinical research areas, Endocrine publishes original articles devoted to basic (including molecular, cellular and physiological studies), translational and clinical research in all the different fields of endocrinology and metabolism. Articles will be accepted based on peer-reviews, priority, and editorial decision. Invited reviews, mini-reviews and viewpoints on relevant pathophysiological and clinical topics, as well as Editorials on articles appearing in the Journal, are published. Unsolicited Editorials will be evaluated by the editorial team. Outcomes of scientific meetings, as well as guidelines and position statements, may be submitted. The Journal also considers special feature articles in the field of endocrine genetics and epigenetics, as well as articles devoted to novel methods and techniques in endocrinology.
Endocrine covers controversial, clinical endocrine issues. Meta-analyses on endocrine and metabolic topics are also accepted. Descriptions of single clinical cases and/or small patients studies are not published unless of exceptional interest. However, reports of novel imaging studies and endocrine side effects in single patients may be considered. Research letters and letters to the editor related or unrelated to recently published articles can be submitted.
Endocrine covers leading topics in endocrinology such as neuroendocrinology, pituitary and hypothalamic peptides, thyroid physiological and clinical aspects, bone and mineral metabolism and osteoporosis, obesity, lipid and energy metabolism and food intake control, insulin, Type 1 and Type 2 diabetes, hormones of male and female reproduction, adrenal diseases pediatric and geriatric endocrinology, endocrine hypertension and endocrine oncology.
