Article Abstract
MicroRNAs (miRNAs) are aberrantly expressed in cervical cancer. miR-7 has been demonstrated to function as both an oncogene and a tumor suppressor in some types of human cancers. In the present study, miR-7 was significantly downregulated in cervical cancer, especially metastatic tumors. Ectopic expression of miR-7 significantly inhibited metastasis and invasion in Hela and C33A cells. Upregulated miR-7 significantly suppressed focal adhesion kinase (FAK) at transcriptional and translational levels. Furthermore, the level of FAK was negatively correlated with miR-7 in cervical cancer tissues. In conclusion, miR-7 inhibited the metastasis and invasion of cervical cancer at least partially through targeting FAK. The findings of this study provide novel insight with potential therapeutic applications for the treatment of metastatic cervical cancer.

Rationale: Chrysotoxine, a bibenzyl derivative from the stems of Dendrobium medicinal herbs, has recently emerged as a promising therapeutic candidate for cervical cancer. This study aimed to characterize chrysotoxine metabolites across multiple hepatocyte species and in rat urine.
Methods: Metabolites were identified and characterized using liquid chromatography coupled with benchtop Orbitrap high-resolution mass spectrometry (LC-Orbitrap-MS/MS) combined with Compound Discoverer software.

Objective: The cachexia index (CXI) demonstrates potential as both a diagnostic tool for cachexia and a prognostic tool for survival in cancer. However, CXI's predictive value has not been verified in cervical cancer. The purpose of this study is to investigate the prognostic value of the CXI in patients with cervical cancer treated with radiotherapy.

The European Council recommends adopting risk-based screening when relevant. In triaging HPV-positive women, it can be an effective strategy to reduce overtreatment and referral to colposcopy. HPV genotyping and p16/ki67 expression may allow a better risk stratification than cytology.

Background: Sub-Saharan Africa (SSA) bears the highest global burden of cervical cancer. Living with the disease is a complex experience, leading to significant changes across various biopsychosocial dimensions, which in turn affect the quality of life of affected women.
Aims: This review aimed to synthesize available scientific evidence on the life experiences of women diagnosed with cervical cancer in SSA in order to generate valuable insights into the care of the affected population.

This study explores effective treatment methods for chronic secondary lymphedema after radical cervical cancer surgery combined with pelvic lymphadenectomy. In cases where conservative treatment was ineffective, we investigated whether multiple injections of indocyanine green can effectively improve the outcomes of lymphatic-venous anastomosis under microscopy. Preoperative lymphatic imaging was used to localize functional vessels, guiding distal left lower limb lymphatic reconstruction.
