Background
The lung cancer is the main cause of cancer death, and according to statistics, 733.3 ten thousands of lung cancers occur in a national population in 2015, and 610.2 ten thousands of lung cancers are the first death. The genotyping can guide the diagnosis and treatment of lung cancer, and the gene detection guide the treatment of lung cancer becomes a new medical mode at present. For example, the National Comprehensive Cancer Network (NCCN) published guidelines indicate that the detection of genes such as EGFR and ALK is required for the diagnosis and treatment of non-small cell lung cancer; when EGFR is sensitive and mutated, EGFR-TKIs targeted drugs are recommended as first-line drugs; in the presence of mutations such as KRAS, EGFR-TKIs are not recommended. In addition, studies have shown that the overall survival and progression-free survival of lung cancer patients undergoing gene-based therapy is significantly higher than that of patients undergoing conventional therapy. Therefore, a product capable of detecting the hot spot mutation site of the lung cancer targeted drug gene is developed, and the survival time of a lung cancer patient can be improved.
The development of a new generation of high-throughput target sequence capture sequencing technology has been widely applied to various biological and medical research. Compared with probe capture, the capture of the target sequence by using the multiple PCR has the obvious advantages of simple operation, low cost, large enrichment of target DNA sequences in a short time and the like, and greatly shortens the detection process and the detection time. However, in general, the more target regions that are to be captured by multiplex PCR, the lower the specificity, accuracy, and uniformity of amplification, and the greater the difficulty of implementing the multiplex PCR capture technique.

Claims (7)
1. A gene detection kit for lung cancer targeted drugs comprises: detecting a specific primer group of the lung cancer targeted drug gene; the specific primer set includes specific primers designed for target regions of genes shown in the following table:
the specific primer group comprises specific primers shown as SEQ ID NO. 1-SEQ ID NO. 56.
2. The kit of claim 1, wherein: the 5' end of each specific primer in the specific primer group is also connected with a universal sequence required by library construction and sequencing.
3. The kit of claim 2, wherein: the universal sequence is selected from a common primer, a joint and a specific label.
4. A gene detection primer group for lung cancer targeted drugs is characterized in that: a specific primer set for use in a kit according to any one of claims 1 to 3.
5. A method of library construction of drug-targeted genes for lung cancer, for non-disease diagnostic purposes, comprising the steps of: according to the requirement of a sequencing platform library, the kit of any one of claims 1 to 3 or the specific primer group of claim 4 is used for carrying out multiplex PCR amplification on the template DNA to obtain an amplicon library, and the amplicon library is purified and mixed to obtain the library of the lung cancer targeted drug genes.
6. The library building method of claim 5, wherein: the method further comprises the steps of:
(1) connecting a public primer as a specific primer group at the 5' end of a specific primer sequence shown in SEQ ID NO. 1-SEQ ID NO. 56, performing multiple PCR amplification on template DNA to obtain a first-step PCR reaction product, and purifying the first-step PCR reaction product;
(2) carrying out second-step PCR reaction on the purified first-step PCR product, a sequencing joint and a label joint to obtain a second-step PCR reaction product, purifying the second-step PCR reaction product, and mixing to obtain a library of the lung cancer targeted drug gene; wherein the tag linkers used for different template DNAs are different.
7. A library of lung cancer drug-targeting genes obtained using the library construction method of claim 5 or 6.
