Problem: Cervical cancer has been recognized as the second most common cancer in women worldwide. Previous studies have reported that some circular RNAs (circRNAs) can influence the progression of cervical cancer. However, more researches are still required to unveil the underlying mechanism of how circRNAs regulate the progression of such cancer. We aimed at unveiling the mechanism of how circ_0060551 effected the progression of cervical cancer.
Method Of Study: RT-qPCR and western blot assays were used to detect the expression and protein levels. Mechanism experiments were conducted to investigate the relationship among circ_0060551, TPD52, miR-520a-5p and ELAVL1. Rescue assays were mainly carried out to verify how circ_0060551 influenced the migration and invasion of cervical cancer cells.
Results: According to the results, circ_0060551 was upregulated in cervical cancer cells and could promote the migration and invasion of cells via TPD52. In addition, circ_0060551 could up-regulate TPD52 expression through a ceRNA model to target miR-520a-5p. Moreover, circ_0060551 could stabilize the mRNA expression of TPD52 via recruiting ELAVL1.
Conclusion: Our study proved that circ_0060551 could promote the migration and invasion of cervical cancer cells.

Purpose: The quality of cervical cancer intracavitary brachytherapy (ICBT) depends on the training and experience of the radiation oncologist (RO). The present study was performed to establish primary learning curve for ICBT.
Materials And Methods: Forty-three skill parameters were identified for performing ICBT and were included for Brachytherapy Proficiency Assessment and Scoring System (Brachy-PASS) questionnaire.

Each year, the American Cancer Society estimates the numbers of new cancer cases and deaths in the United States and compiles the most recent data on population-based cancer occurrence and outcomes using incidence data collected by central cancer registries (through 2021) and mortality data collected by the National Center for Health Statistics (through 2022). In 2025, 2,041,910 new cancer cases and 618,120 cancer deaths are projected to occur in the United States. The cancer mortality rate continued to decline through 2022, averting nearly 4.

BACKGROUND The thyroglossal duct cyst, which develops from the midline migratory tract between the foramen cecum and the anatomic location of the thyroid, is the most prevalent congenital abnormality of the neck, accounting for about 70% of all cervical neck masses in children and 7% in adults. Only up to 1% of these abnormalities contain malignant thyroid tissue, with 90% of those cases being papillary thyroid carcinoma. Thyroglossal duct cyst is rarely linked to carcinoma.

Background: Chromosomal instability (CIN) has been identified as a factor that increases the susceptibility of tumor cells to kinesin family member 18A (KIF18A) inhibitors. Limited research exists on genes that are associated with sensitization to KIF18A inhibitors (KIF18Ais). Our study aimed to identify a gene linked to heightened sensitivity to KIF18Ais in cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC) and uterine corpus endometrial carcinoma (UCEC).
