Background: Cervical cancer is the most common cancer among Indian women. This cancer has well defined pre-cancerous stages and evolves over 10-15 years or more. This study was undertaken to identify differentially expressed genes between normal, dysplastic and invasive cervical cancer.
Materials And Methods: A total of 28 invasive cervical cancers, 4 CIN3/CIS, 4 CIN1/CIN2 and 5 Normal cervix samples were studied. We have used microarray technique followed by validation of the significant genes by relative quantitation using Taqman Low Density Array Real Time PCR. Immunohistochemistry was used to study the protein expression of MMP3, UBE2C and p16 in normal, dysplasia and cancers of the cervix. The effect of a dominant negative UBE2C on the growth of the SiHa cells was assessed using a MTT assay.
Results: Our study, for the first time, has identified 20 genes to be up-regulated and 14 down-regulated in cervical cancers and 5 up-regulated in CIN3. In addition, 26 genes identified by other studies, as to playing a role in cervical cancer, were also confirmed in our study. UBE2C, CCNB1, CCNB2, PLOD2, NUP210, MELK, CDC20 genes were overexpressed in tumours and in CIN3/CIS relative to both Normal and CIN1/CIN2, suggesting that they could have a role to play in the early phase of tumorigenesis. IL8, INDO, ISG15, ISG20, AGRN, DTXL, MMP1, MMP3, CCL18, TOP2A AND STAT1 were found to be upregulated in tumours. Using Immunohistochemistry, we showed over-expression of MMP3, UBE2C and p16 in cancers compared to normal cervical epithelium and varying grades of dysplasia. A dominant negative UBE2C was found to produce growth inhibition in SiHa cells, which over-expresses UBE2C 4 fold more than HEK293 cells.
Conclusions: Several novel genes were found to be differentially expressed in cervical cancer. MMP3, UBE2C and p16 protein overexpression in cervical cancers was confirmed by immunohistochemistry. These will need to be validated further in a larger series of samples. UBE2C could be evaluated further to assess its potential as a therapeutic target in 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.
