多重原发性癌症 (MPCs) 可以表明遗传性倾向. 仅基于MPC的基因测试显示了与基于指南的测试相比的诊断产量,这表明MPC是确定遗传癌症风险的独立标准.
科学领域:
- 遗传学 是一个遗传学.
- 在瘤学瘤学.
- 医学诊断 医学诊断 医学诊断
背景情况:
- 多重原发性癌症 (MPCs) 通常表明潜在的遗传性癌症倾向.
- 目前的基因测试指南可能会忽略MPC患者,这些患者不符合特定癌症类型的标准.
- 评估MPC作为生殖系遗传测试的独立标准至关重要.
研究的目的:
- 为了比较基于指南的与基于MPC的生殖系遗传测试的致病变体 (PV) 诊断产量.
- 评估多种原发性癌症作为基因检测的独立指标的有用性.
- 为了确定单独的MPC状态是否可以有效地识别遗传性癌症倾向.
主要方法:
- 预期招募62名患有两种或两种以上病理确认的原发性癌症的患者.
- 分类为指南 (n=29) 和非指南 (基于MPC,n=33) 组.
- 使用25基因小组和BRCA1/2测序进行生殖系遗传测试.
主要成果:
- 在6.5%的患者 (4/62) 中发现了致病变体 (PVs).
- 在指南 (6.9%) 和非指南 (6.1%) 组 (p=0.763) 之间,诊断产量相似.
- 一名患有>=3种癌症的患者在不符合Li-Fraumeni综合征标准的情况下出现TP53删除.
结论:
- 仅基于多种原发性癌症 (MPC) 的生殖系遗传测试表明,诊断产量与基于指南的测试相当.
- 可以将MPC视为基因测试的独立标准.
- 这种方法可以改善遗传性癌症倾向的识别.
