- a method for determining breast cancer characterized in that the presence or absence of an endothelial cell-specific protein C receptor (EPCR) in a biological sample can be used, and the presence of the substance is determined as positive (Patent Document 1)
- Determining a level of expression of a breast cancer-related gene in a biological sample from a patient, the level of expression of the sample comprising There has been proposed a method (see Patent Document 3) for determining that the subject is suffering from breast
- DNA copy number polymorphism was reported in 2004 as having a state where DNA is amplified or deleted over a region of about 100 kb in a specific chromosomal region. Have been reported to have about 20,000 DNA copy number polymorphisms.
- DNA copy number polymorphism is a phenomenon in which the number of copies of a sequence from several thousand base pairs to several million base pairs varies depending on the individual. Due to the DNA copy number polymorphism in the gene region, usually human genes are inherited from the parents' genomes, one copy at a time, and two copies are inherited, but depending on the individual, only one copy of the gene per cell, or It is known that 3 copies or more exist.
- SNPs single nucleotide polymorphisms
- the present inventors have reported a method for determining the onset sensitivity of endometrial cancer and colon cancer using DNA copy number polymorphism as an index (see Patent Document 4). However, no DNA copy number polymorphism that can determine breast cancer susceptibility has been known so far.
- breast cancer lowers cancer risk by correcting lifestyle, and that early detection and treatment are possible through regular screening, reducing cancer mortality. For this reason, if we can determine the susceptibility to breast cancer development, we will actively promote strong motivation and practice for actions that lower the risk of developing breast cancer (exercise physical activity such as sports, do not gain weight, refrain from drinking), and cancer screening. You can expect to raise your awareness of receiving it. As a result, cancer prevention can be realized, and even if cancer develops, early detection and treatment are possible, and the cancer mortality rate can be greatly reduced.

Subsequently, it was considered whether the breast cancer development predisposition could be verified with high accuracy, simplicity and low cost from the copy number increase / decrease in the DNA copy number polymorphism region, and analysis by quantitative PCR was performed. In the quantitative PCR method, the present inventors have focused on a specific region among the chromosomal regions identified by the microarray method. That is, a chromosomal region narrower than the microarray method is detected.

Abstract
Description
マイクロアレイ法に用いた検体数よりも6倍以上多い検体数を用いて定量PCR法を行い、乳がん発症体質との関連性を検証したところ、例えばプライマーセット(Hs03899300_cn)を用いて検出した染色体領域(15q26.3 [99,845,920-99,846,025])のDNAコピー数減少(コピー数1.5未満)の頻度は健常者群では25.9%であるのに対して、乳がん患者群では76.7%であり、オッズ比9.4であることがわかった。すなわち、この領域にDNAコピー数減少がある場合、乳がんになりやすいことを見出した。同様に、プライマーセット(Hs03908783_cn)を用いて検出した染色体領域(15q26.3 [99,847,947-99,848,043])のDNAコピー数減少(コピー数0.5未満)の頻度は健常者群では10.2%であるのに対して、乳がん患者群では23.8%であり、オッズ比2.8であることもわかった。すなわち、この領域にDNAコピー数減少がある場合、乳がんになりやすいことを見出した。さらに、かかる2つの領域の定量PCR法による結果を基にした判別分析を行うと、乳がん患者群の中で「乳がん」と判定されるのは83.9%(感度)であるのに対して、健常者群の中で「乳がんではない」と判定されるのは81.0%(特異度)であった。すなわち、乳がん発症感受性の高精度な判定方法を見出し、本発明を完成するに至った。
