Human papillomavirus genome associated correlates of disease progression and treatment response for cervical neoplasms and cancer
Aim
Description
The results of the project will improve the early diagnosis of human papillomavirus (HPV) related cancers using a personalised medicine approach; it will increase the number of healthy years, preserve reproductive potential, and improve the overall quality of life of the affected individuals and their productive input into society. Despite the availability of vaccinations, HPV, which causes cancer, remains a serious public health problem worldwide and in Latvia. Latvia still registers 32.5 cervical cancer cases per 100,000 population, which indicates insufficient preventive efforts and requires an in-depth update of determinants of HPV pathogenesis.
Possible solutions
- Identify common cancer-causing HPV genotypes that will allow the application of HPV tests to identify high-risk patients.
- Identify variants of HPV mutations that affect the course of the disease, which will provide prognostic tools for personalised monitoring of patients.
- Identify HPV genomes integrated into patients' genome that may serve as an early marker of cancer predisposition.
The project will involve doctoral students from RSU and residents of the Pauls Stradiņš University Clinical Hospital.

- Annual Congress of the International Society for Vaccines (2023)
The HPV LZP project group participated in the annual congress of the International Society for Vaccines (ISV) in Lausanne, Switzerland on 22-24 October 2023. Lība Sokolovska joined on site, and Juris Jansons and Maria Issagouliantis virtually to present project results.
The group presented three posters:
