The goal of this study was to determine the clinical and epidemiological trends of cervical cancer in young Korean women. Social behavior including sexual habits has changed in Korean women, with sexual activity commencing at a younger age. These changes are likely to influence certain risk factors of cervical cancer, resulting in changing trends in the occurrence of the disease.
The incidence of cervical cancer in women less than 35 years-old between January 1990 and December 2006 was analyzed, and available medical records from January 1996 to December 2006 were reviewed. The clinical, pathological and epidemiologic characteristics and changing trends among these young patients were analyzed.
Over the last two decades, the incidence of young (< 35 years) cervical cancer patients increased, more patients had an aggressive form of the disease, and there was a higher rate of women with more advanced education. Human papillomavirus (HPV) infection was detected in 94.0% of the women (63/67) tested. HPV 16 (82.5%) and HPV 18 (12.7%) were the two most common viral infections detected throughout the study period.
The changing trends and risk factors identified suggest a need for more active education of young women about cervical cancer prevention strategies. In addition, young women are strongly recommended to undergo a regular screening test and HPV vaccination.

It is well known that human papillomavirus (HPV) is the main cause of cervical neoplasia, and hydrogen peroxide-producing lactobacilli are the most important microorganisms for maintaining the balance of the vaginal ecosystem. The purpose of our study was to investigate the relationship of hydrogen peroxide-producing lactobacilli, cervical neoplasia and high-risk HPV.
We enrolled 1138 women with abnormal cervical smears or cervicograms who were referred to the department of Obstetrics and Gynecology at Chonnam National University Medical School. In all of them, 1,138 vaginal swabs were collected for the qualitative assay of hydrogen peroxide producing lactobacilli and 150 cervical swabs were used for the HPV hybrid capture II test without regard to the subjects' pregnancy status. In the non-pregnant women, 880 cervical biopsies and/or loop electrosurgical excision procedures were performed for making the histological diagnosis.
There was no significant difference not only between the distribution of H2O2 producing lactobacilli and the cervical histology, but also between the distribution of H2O2 producing lactobacilli and the positivity for high-risk HPV.
Both cervical neoplasia and high-risk HPV may not be influenced by the existence of hydrogen peroxide producing lactobacilli in the vagina.
