CASE-CONTROL STUDIES OF SELECTED CANCER SITES

这个项目的目的是在分析研究中调查 选定癌症的病因。具体的癌症部位和假设是 被选中的人显然需要调查，但已经 在其他地方很难研究。最近的病例对照研究 已完成或正在进行的研究包括以下地点或类型的研究： 乳腺癌，儿童和成人膀胱癌，结直肠癌， 皮肤T细胞淋巴瘤，非霍奇金淋巴瘤，白血病，鼻癌， 睾丸癌，间皮瘤，眼内黑色素瘤，卵巢癌， 宫颈癌，绒毛膜癌，胰腺癌，前列腺癌， 多发性骨髓瘤，食道癌，外阴癌，阴道癌， 子宫内膜癌和肺癌。这些研究的重点要么是肿瘤 以前没有进行过分析研究(例如，因为稀有性 肿瘤)或基于难以评估的假设(例如，因为 暴露的普遍程度或检测低水平影响的需要 暴露水平)。因为这些研究往往是第一次或大多数 到目前为止，他们收集了广泛暴露的数据，通常 从面谈和医疗记录中。

The purpose of this project is to investigate, in analytic studies, the etiologies of selected cancers. Specific cancer sites and hypotheses are selected for which the need for investigation is clear but which have been difficult to study elsewhere. Case-control studies either recently completed or in progress include studies of the following sites or types: breast cancer, childhood and adult bladder cancer, colorectal cancer, cutaneous T-cell lymphoma, non-Hodgkin's lymphoma, leukemia, nasal cancer, testicular cancer, mesothelioma, intraocular melanoma, ovarian cancer, cervical cancer, choriocarcinoma, pancreatic cancer, prostate cancer, multiple myeloma, esophageal cancer, vulvar cancer, vaginal cancer, endometrial cancer, and lung cancer. The studies focus either on tumors that have not been studied analytically before (e.g., because of the rarity of the tumor) or on hypotheses that are difficult to assess (e.g., because of the prevalance of the exposure or the need to detect an effect at low levels of exposure). Since these studies are often the first or most thorough to date, they collect data on a wide range of exposures, usually from interviews and medical records.
