Persistent infections with high-risk subtypes of the human papillomavirus (HPV) are recognized as the etiological factor for developing cervical cancer. The aim od this study was to identify a miRNA profile in patients with early-stage cervical cancer with positive lymph node metastasis treated. Formalin-fixed paraffin-embedded (FFPE) tissue samples of patients with a diagnosis of early-stage cervical cancer treated by radical hysterectomy with lymphadenectomy were collected.
Cervical carcinoma (CC) is one of the most common cancers in women from countries with emerging economies; in Mexico, CC has the second highest incidence and mortality rate. Several studies have demonstrated that the most important prognostic factor is lymph node metastasis in early-stage CC patients prior to radical hysterectomy (RH) with bilateral pelvic lymphadenectomy (BPL), in which positive lymph node metastasis decreasing overall survival (OS) from 80% to 53% at 5 years.
MicroRNAs (miRNAs) are single-strand RNAs comprising approximately 21-23 nucleotides. miRNAs regulate gene expression through the inhibition of posttranscriptional events and, in some cases, induce the degradation of their target messenger RNA. In cancer, miRNAs can function as both oncogenes and/or as tumor suppressor genes depending on the function of their target genes.
Formalin-fixed paraffin-embedded (FFPE) tissue blocks from CC patients diagnosed between January 2006 and December 2013 at the Department of Oncologic Gynecology of the National Cancer Institute (Mexico City) were analyzed with the intention of selecting those with a confirmed histopathological diagnosis of stages IB1 or IIA1 CC treated with RH and BPL. Total RNA was extracted from 5 (10-µm) sections for selected tissues.For the clinical correlation analysis, the samples were divided into 2 groups: 1 with positive occult lymph node metastasis pathology and 1 without lymph node metastasis pathology. For both groups, patients were matched for age, tumor size and presence of lymphovascular permeation.
The identification of global miRNA profiles was performed using GeneChip miRNA 3.0 Array (Affymetrix, Cat. 902018) following the manufacturer's instructions. the microarray was hybridized and washed using the Affymetrix Fluidics Station 450 and scanned with the Affymetrix GeneChip Scanner 3000. After processing the images, the raw data were processed. To obtain the miRNA profile, the processed samples were divided into 2 groups, samples with lymph node metastasis and samples without lymph node metastasis. Differentially expressed miRNAs were identified using a cutoff value of p <0.01 and a fold change (FC) of 1.5. miRNAs that met these criteria were classified as over-expressed or under-expressed.

Morphological abnormalities of the cervical EPITHELIUM, usually revealed in PAP SMEAR, which do not meet the criteria for squamous CERVICAL INTRAEPITHELIAL NEOPLASIA or SQUAMOUS CELL CARCINOMAS of the CERVIX . It may be a sign of infection with certain types of human papillomavirus (HPV).or sign of a benign (not cancer) growth, such as a cyst or polyp or, in menopausal women, of low hormone levels. More testing, such as HPV test, may be needed.
A network of nerve fibers originating in the upper four cervical spinal cord segments. The cervical plexus distributes cutaneous nerves to parts of the neck, shoulders, and back of the head, and motor fibers to muscles of the cervical spinal column, infrahyoid muscles, and the diaphragm.
