Since the Pap test was introduced in the 1940s, there has been an approximately 70% reduction in the incidence of squamous cell cervical cancers in many developed countries by the application of organized and opportunistic screening programs. The efficacy of the Pap test, however, is hampered by high interobserver variability and high false-negative and false-positive rates. The use of biomarkers has demonstrated the ability to overcome these issues, leading to improved positive predictive value of cervical screening results. In addition, the introduction of HPV primary screening programs will necessitate the use of a follow-up test with high specificity to triage the high number of HPV-positive tests. This paper will focus on protein biomarkers currently available for use in cervical cancer screening, which appear to improve the detection of women at greatest risk for developing cervical cancer, including Ki-67, p16(INK4a), BD ProEx C, and Cytoactiv HPV L1.

Objective: In Japan, the current coverage rate of human papillomavirus (HPV) vaccination is only 30%, and the rate of biennial cervical screening is 40%. The Japanese Government has attempted to increase the coverage of HPV vaccination and cervical screening. We analyzed the cost-effectiveness of the 9-valent HPV vaccine and cervical screening in Japan.

Investigating protein biomarkers such as E7, pRb, EGFR and p16 can help assess the efficacy of these treatments. <b>Materials and Methods:</b> There were 5 groups in this study: 2 control groups (C- and C+) and 3 treatment groups (each receiving one of three doses).

Objective: To comprehensively investigate the predictive value of thyroid hormone sensitivity parameters for cervical lymph node metastasis in patients diagnosed with differentiated thyroid cancer (DTC) undergoing total thyroidectomy and neck lymph node dissection.
Methods: A retrospective cohort study was conducted involving patients diagnosed with DTC and evaluated for cervical lymph node metastasis. Relevant demographic, tumour, lymph node and thyroid hormone sensitivity parameter data were extracted from medical records and laboratory reports.

Background: This study aimed to investigate the potential utility of Epithelial-mesenchymal transition (EMT) signaling cell detection in the early diagnosis of cervical lesions.
Methods: Enrichment of cervical epithelial cells was carried out using a calibrated membrane with 8-μm diameter pores. RNA-in situ hybridization (RNA-ISH) was employed to detect and characterize EMT cells utilizing specific EMT markers.
