PURPOSE: Patients after radical vaginal trachelectomy (RVT) need specific follow-up treatment because their problems differ from those of other gyneco-oncologic patients. Anatomic changes after surgery complicate examinations. Recognition and treatment of these issues require physician's expertise. PATIENTS AND METHODS: We evaluated the follow-up data of 70 patients who underwent RVT for early cervical cancer between 03/2010 and 12/2013. The follow-up interval in the first 2 years was 3 and 6 months in the following 2 years...

Human papillomavirus (HPV) is the primary infectious agent for the development of cervical cancer, although the presence of the virus alone is insufficient for viral development and proliferation; this can be attributed to the increase in potential oncogenic risk, along with other risk factors. In the present investigation, the prevalence of high-risk HPV was determined from samples of premalignant or malignant cervical cytology in women from the southern region of Ecuador. The kit we used was able to detect genotypes 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, and 59...

Narrow band imaging with magnifying endoscopy (NBI-ME), which is useful for the assessment of micro-vessels, has excellent diagnostic potential for early gastrointestinal epithelial neoplasia. Conventional diagnostic tools for uterine cervical epithelial tumors are still unsatisfactory. An accurate diagnostic tool for uterine cervical epithelial tumors is required to preserve the reproductive ability of young women with uterine cervical tumors. Flexible NBI-ME was performed in patients with cervical squamous cell lesions that required further examinations based on their Pap smear results (cytology ≥ low-grade squamous intraepithelial lesion) at Kagawa University Hospital between April 2014 and April 2015...

This editorial by Dr. Leopold G. Koss appeared in the January 1980 issue of Acta Cytologica. It addressed recent critical opinions in the general media on cervical screening and its costs. It marked the beginning of a more critical approach to cytology by the lay press, health care providers, and epidemiologists. It was also the first of a series of highly informative editorials by Dr. Koss that illustrated the critical issues of cytology during the 1980s. The elegance and clarity of his articles reflect the high standard of editorial writing in Acta Cytologica at this time...

Although human papillomavirus (HPV) vaccines offer enormous promise for the ultimate control and possible elimination of cervical cancer, barriers to uptake and coverage of the vaccine both in high- and low/middle-income settings mean that advances in secondary prevention continue to be essential to prevent unnecessary deaths and suffering from cervical cancer for decades to come. While cytology (the Pap smear) has reduced cervical cancer incidence and prevalence in jurisdictions where it has been systematically implemented in population-based programs-mainly in high-income settings-limitations inherent to this method, and to program delivery, leave many women still vulnerable to cervical cancer...

Cervical cancer is an important public health problem. Pap smear is the leading strategy of screening programs for cervical cancer worldwide. However, delayed diagnosis leads to more aggressive and less effective treatments. Patients with uterine cervix malignancies who are referred for radiotherapy have advanced-stage disease, which results in high rates of locoregional recurrence. The use of radiotherapy as a treatment for cervical cancer causes morphological changes in neoplastic and non-neoplastic epithelial cells, as well as in stromal cells, which make it difficult to diagnose the residual lesion, resulting in a dilemma in cytopathological routine...

INTRODUCTION: The current Australian National Cervical Screening Program (NCSP) involves biennial, cytology-based screening of women from the age of 18 years. From December, 2017 this will change to a five-yearly human papilloma virus-based screening commencing at age 25. There is some concern that the new program may delay the opportunistic detection of cervical cancers in women under 25 years. AIM: (1) To review all cases of invasive cervical cancer in Queensland women under the age of 25 over the last 28 years...

OBJECTIVE: Cervical cancer screening usually requires use of a speculum to provide a clear view of the cervix. The speculum is one potential barrier to screening due to fear of pain, discomfort and embarrassment. The aim of this paper is to present and demonstrate the feasibility of a tampon-sized inserter and the POCkeT Colposcope, a miniature pen sized-colposcope, for comfortable, speculum-free and potentially self-colposcopy. STUDY DESIGN: We explored different designs using 3D computer-aided design (CAD) software and performed mechanical testing simulations on each...

Automation-assisted cervical screening via Pap smear or liquid-based cytology (LBC) is a highly effective cell imaging based cancer detection tool, where cells are partitioned into "abnormal" and "normal" categories. However, the success of most traditional classification methods relies on the presence of accurate cell segmentations. Despite sixty years of research in this field, accurate segmentation remains a challenge in the presence of cell clusters and pathologies. Moreover, previous classification methods are only built upon the extraction of hand-crafted features, such as morphology and texture...

The natural history of precancerous lesions and cervical cancer in Israeli women differs from that reported in the world. In 2011, 244 women were diagnosed in Israel with invasive cervical cancer, with the mortality of 79 women. The incidence of cervical cancer in Israel is about 5 new cases per year per 100,000 women (5.4 Jewish, 3.2 Arab). This figure is very low compared with statistics presented in other countries and has not changed over the last decades. The vast majority of Israeli women were diagnosed due to symptoms and not following Pap smear screening...
