Abstract: Disclosed are a method of determining an HPV integration site in a genome of a human tissue sample and a system thereof. The method comprises: subjecting genome DNA of the human tissue sample to a first sequencing, to obtain a sequencing result; determining DNA fragments containing both HPV sequence and human genome sequence, based on the sequencing result; determining a pair of amplification primers based on the DNA fragments containing both HPV sequence and human genome sequence, subjecting the genome DNA of the human tissue sample to PCR amplification using the pair of amplification primers, to obtain PCR product; and subjecting the PCR product to a second sequencing, to determine the integration site in a genome of the human tissue sample. The method is easy to be operated with low cost, high efficiency and excellent repeatability, which may be used to detect all HPV genotypes one time, and may rapidly and accurately determine detailed sequence information and integration site.
