Filter by:The clinical diagnosis and treatment data of 300 cases of cervical neuroendocrine tumors were collected, including age, preoperative biopsy pathology results, postoperative histopathological results, TCT results, and colposcopy biopsy pathology results. At the same time, paraffin tissue specimens (remaining specimens after pathological diagnosis) from 100 cases of cervical neuroendocrine tumors from multiple centers across the country were collected to establish a cervical neuroendocrine tumor data follow-up database. Protein concentration and omics analysis were performed on the data results, to evaluate the molecular characteristics and prognosis of cervical neuroendocrine tumor proteins, and to preliminarily explore its clinical application value.
Cervical cancer screening is important as it enables identification of women at increased risk of the disease, but high-quality diagnostics of screen-positive women and effective treatment of those with precancer are critical in preventing progression to cancer. With the current transition from cytology-based to primary human papillomavirus (HPV)-screening and a growing proportion of HPV-vaccinated women, diagnostics of screen-positive women will become more challenging in the decades to come. Thus, there is a need to explore how to improve diagnostics while ensuring a low number of unnecessary procedures such as colposcopy and the collection of multiple cervical biopsies. The overall purpose is: - To investigate the diagnostic accuracy of cervical precancer when using a colposcopic scoring system in the diagnostic work-up of screen-positive women. - To investigate the performance of a colposcopic scoring system to identify women without cervical precancer in whom collection of biopsies can be safely omitted.
The goal of this observational study is to compare the accuracy and sensitivity of High-throughput human papilloma virus(HPV) typing and integrated assays with routine screening protocols (Cobas HPV test combined with thinprep cytologic test(TCT) for the detection of cervical intraepithelial neoplasia in the general and hospital populations. The main questions it aims to answer are: - High-throughput HPV typing and integrated assays can screen for ≥ cervical intraepithelial neoplasia (CIN2 or CIN3) with high sensitivity and accuracy. - High-throughput HPV typing and integrated assays can be promoted as a screening tool for cervical cancer. Participants will be screened with routine screening protocols (Cobas HPV test combined with TCT test), and if the results are abnormal, colposcopy and cervical biopsy will be performed.
This study evaluates the Dynamic Spectral Imaging (DSI) Colposcope (DySIS) in it's ability to diagnose cervical dysplasia. Half of participants with be examined by the DySIS colposcope, there the other half will be examined by standard colposcopy.
