评估环境、家庭和职业暴露与睾丸生殖细胞肿瘤风险之间关系的病例对照研究 (TESTIS)
一项多中心病例对照研究,以评估产前和产后早期环境、家庭和职业暴露与成年期睾丸生殖细胞肿瘤风险之间的关联
睾丸生殖细胞肿瘤是 15 至 45 岁男性中最常见的癌症,在法国的发病率在 30 年内翻了一番。 原因尚不清楚,但强烈怀疑环境因素的作用,尤其是在发育的关键时期。 在这个关键时期,关于环境暴露的可靠数据很少。不一致的发现和现有研究的局限性强调了进行具有足够统计能力的研究以检测在脆弱性关键窗口期间暴露引起的风险的重要性。
我们进行了一项多中心病例对照研究来评估这种关联。 病例和对照将在 18 个月内登记。 他们将接受专业电话采访者的采访,了解他们的职业和居住历史以及他们在国内接触杀虫剂和其他滋扰的情况。
将向每个病例和对照提出一项可选的生物学研究,以评估已知与睾丸癌相关的遗传多态性。
还将联系病例和对照的母亲(或近亲)(在儿子同意的情况下)。 如果他们同意参加,他们还将接受采访,了解他们的儿子在产前和早年生活中接触杀虫剂和其他滋扰的情况。
病例将与年龄(+/- 2 岁)和招募中心的 2 名对照(每组一名)相匹配。
研究概览
详细说明
将使用地理信息系统根据受试者的居住历史评估对杀虫剂的环境暴露。
职业接触杀虫剂和其他滋扰将由负责对所有受试者和母亲的职业进行编码的工业卫生师进行评估。
家庭接触杀虫剂将从家庭杀虫剂使用的类型、目标和频率进行评估。
基于这 3 个暴露来源,将为每个案例和每个对照计算一个暴露分数。
