    • The present invention provides a new method for detecting the presence of gynecological carcinomas in a patient. The method, which comprises detecting the presence of lysophosphatidic acid in a plasma sample of the patient, is useful for detecting ovarian carcinoma, cervical carcinoma, endometrial carcinoma, and peritoneal carcinoma. In a preferred embodiment the method comprises: providing a blood specimen from the patient, obtaining a plasma sample from the blood specimen under conditions which minimize the release of lysophosphatidic acid from the platelets in the blood specimen into the plasma, extracting lipids from the plasma, and detecting the presence of lysophosphatidic acid in the lipid extract. A new method for extracting lysophosphatidic acid from a biological fluid is also provided. The method which comprises acidifying the biological fluid and extracting the lysophosphatidic acid from the acidified sample with an organic solvent is useful for extracting greater than 80 % of the lysophosphatidic acid in the biological fluid.
    • 本发明提供了一种用于检测患者中妇科癌存在的新方法。 该方法包括检测患者血浆样品中溶血磷脂酸的存在,可用于检测卵巢癌,子宫颈癌,子宫内膜癌和腹膜癌。 在优选实施方案中,该方法包括:从患者提供血液标本,在使血液样本中血小板中溶血磷脂酸释放到血浆中的条件下从血液标本获得血浆样品,从血浆中提取脂质, 并检测脂质提取物中溶血磷脂酸的存在。 还提供了一种从生物液体中提取溶血磷脂酸的新方法。 包括酸化生物流体并用有机溶剂从酸化样品中提取溶血磷脂酸的方法可用于提取生物流体中大于80%的溶血磷脂酸。
