Active clinical trials for "Uterine Cervical Neoplasms"

This clinical trial studies conservative surgery in treating patients with low-risk stage IA2 or IB1 cervical cancer. Conservative surgery is a less invasive type of surgery for early stage cervical cancer and may have fewer side effects and improve recovery.

The purpose of this study explores the usefulness of urine samples for cervical cancer screening in human immunodeficiency virus (HIV)-infected women. Cervical cancer occurs when women are infected with the human papillomavirus (HPV), which can cause changes in the cells that lead to cervical precancer and, eventually, cervical cancer if untreated. However, urine HPV testing has not been well validated low- and middle-income country settings, with no data available to guide its use in HIV-infected women.

Cervical cancer remains a major public health challenge in low- and middle-income countries (LMICs) due to financial and logistical issues. The World Health Organization (WHO) recommendation for cervical cancer screening in LMICs includes Human Papillomavirus (HPV) testing as primary screening followed by visual inspection with acetic acid (VIA) and treatment. However, VIA is a subjective procedure dependent on the healthcare provider's experience. Therefore, an objective approach based on quantitative diagnostic algorithms is desirable to improve performance of VIA. With this objective and in a collaboration between the Gynecology and Obstetrics Department of the Geneva University Hospital (HUG) and the Swiss Institute of Technology (EPFL), our group started the development of an automated smartphone-based image classification device called AVC (for Automatic VIA Classifier). Two-minute videos of the cervix are recorded during VIA and classified using an artificial neural network (ANN) and image processing techniques to differentiate precancer and cancer from non-neoplastic cervical tissue. The result is displayed on the smartphone screen with a delimitation map of the lesions when appropriate. The key feature used for classification is the dynamic of cervical acetowhitening during the 120 second following the application of acetic acid. Precancerous and cancerous cells whiten more rapidly than non-cancerous ones and their whiteness persists stronger overtime. Our aim is to assess the diagnostic performance of the AVC and to compare it with the performance of current triage tests (VIA and cytology). Histopathological examination will serve as reference standard. Participants' and providers' acceptability will also be considered as part of the study. The study will be nested in an ongoing cervical cancer screening program called "3T-approach" (for Test, Triage and Treat) which includes HPV self-sampling for women aged 30 to 49 years, followed by VIA triage and treatment if needed. The AVC will be evaluated in this context. The study's risk category is A according to swiss ethical guidelines. This decision is based on the fact that the planned measures for sampling biological material or collecting personal data entail only minimal risks and burdens.

Cervical cancer is a rare pathology. Recent studies showed that the risk of recurrence is higher for patients treated by coelioscopy in comparison with laparotomy. It could be explained by the spread of circulating tumor cells (CTC) due to tumor mobilization during different steps of the surgery. The primary goal is to evaluate the spread of CTC during surgery on peripheral blood samples. The secondary outcome is to evaluation the disease-free survival at 3 and 5 years postoperatively. 20 patients with early stage cervical (IA1 to IB2) eligible to coelioscopic stadification and laparoscopic surgery will be included.

The research project applies the protocol of the World Health Organisation for screening of cervical cancer, with testing of hrHPV as first screening, followed by Visual Inspection of the cervix with Acetic Acid for hrHPV-positive women and for women with minor lesions thermo-ablation of affected areas. This procedure is applied in Uganda, India and Bangladesh. In Slovakia hrHPV-positive women are offered Pap-smear and for women with Pap IV lis excision.

The Pocket colposcope has 510k FDA clearance and has been successfully used in almost 1500 unique patients globally in Duke and non-Duke protocols to date. 400 women who are HPV-positive and planned to undergo treatment at 6 Ministry of Health-supported outpatient clinics in Kisumu County will be recruited to the study. After providing informed consent, participants will be randomized 1:1 to either standard-of-care visual inspection or colposcopy with the Pocket Colposcope

The objective of the work described in this protocol is to determine the optical signatures of cervical dysplasia using optical technologies.

Cervical cancer is a relatively common cancer among women living with human immunodeficiency virus (HIV). This study will test women for human papillomavirus (HPV) infection of the cervix. The main purpose of this study is to determine the best way to test for damaged areas of the cervix. Damaged areas of the cervix should be treated and removed to prevent cancer of the cervix. Women in this study will be seen once, twice or three times in a year. Women will provide several samples related to screening for cervical cancer including a swab of the cervix, a self-collected swab of the vagina and urine. Women will have a detailed examination of the cervix called colposcopy and have a few biopsies, or small pinches of the cervix, to look for areas at risk for turning into cancer. If HPV of the cervix is found but treatment of the cervix is not indicated, women will return in 6 months and in 12 months to repeat these tests. Most women will only need 1 visit. Women found to have damaged areas of the cervix at risk for turning into cancer will be referred for treatment. This protocol will compare different tests to understand the best test to identify women at risk for cervical cancer.

The study aims to compare the accuracy of the lateral flow test to detect HPV at the POC with the commercially available GeneXpert HPV test and to determine the diagnostic accuracy and reliability of a multimodal optical imaging system to detect cervical dysplasia, with the gold reference standard of histopathology.
