    摘要: The recently developed liquid-based Papanicolaou (Pap) smear allows not only cytologic evaluation but also collection of DNA for detection of HPV, the causative agent of cervical cancer. We tested these samples to detect somatic mutations present in rare tumor cells that might accumulate in the cervix once shed from endometrial and ovarian cancers. A panel of commonly mutated genes in endometrial and ovarian cancers was assembled and used to identify mutations in all 46 endometrial or cervical cancer tissue samples. We were able also able to identify the same mutations in the DNA from liquid Pap smears in 100% of endometrial cancers (24 of 24) and in 41% of ovarian cancers (9 of 22). We developed a sequence-based method to query mutations in 12 genes in a single liquid Pap smear without prior knowledge of the tumor's genotype.

    摘要: Phosphatidylinositol 3-kinases (PI3Ks) are known to be important regulators of signaling pathways. To determine whether PI3Ks are genetically altered in cancers, we analyzed the sequences of the P13K gene family and discovered that one family member, PIK3CA, is frequently mutated in cancers of the colon and other organs. The majority of mutations clustered near two positions within the P13K helical or kinase domains. PIK3CA represents one of the most highly mutated oncogenes yet identified in human cancers and is useful as a diagnostic and therapeutic target.
