1. Significance of Human Papillomavirus (HPV) Analysis for the Detection of Precancerous Cervical Lesions : Impact of Self Sampling
Sammanfattning : Cervical cancer is the second most common cancer, with about 500 000 new cases per year among women worldwide. With a well-organized screening programme the number of cases can be reduced by more than 50%. In spite of having such a screening programme there are still around 450 new cases yearly in Sweden.

2. Genital human papillomavirus (HPV) infections and their importance for the handling of precancerous lesions of the cervix uteri
Sammanfattning : Background: The development of cervical carcinoma, in a vast majority of cases, is closely related to infections with certain types of the human papillomavirus (HPV). The virus is supposed to exert its oncogenic effect mainly through interference with two proteins that are responsible for growth arrest as a response to DNA damage. LÄS MER
3. The battleground of two Infections and a cancer: Human Papilloma Virus, premalignant lesions of the cervix and their interaction with Human Immunodeficiency Virus in southwestern Nigeria
Sammanfattning : Background: The highest numbers of HIV-infected women are in sub- Saharan Africa, where the natural progression of HIV disease in the absence of treatment results in death before the onset of invasive cervical cancer. With improved access to treatment, several studies outside West Africa demonstrated an increased risk of pre-invasive cervical lesions among HIV-infected women and the positive impact of treatment on the outcome.

4. Epidemiological studies of Helicobacter pylori and its relation to cancer and precancerous lesions in the upper gastrointestinal tract
Sammanfattning : Helicobacter pylori infection is strongly associated with gastric cancer risk. The carcinogenic process is supposed to occur step by step, from a normal gastric epithelium via gastritis, atrophy, intestinal metaplasia to dysplasia. LÄS MER
