Objective: Studies have published the association between the expression of matrix metalloproteinases (MMPs) and the outcome of cervical cancer. However, the prognostic value in cervical cancer remains controversial. This meta-analysis was conducted to evaluate the prognostic functions of MMP expression in cervical cancer.
Methods: A comprehensive search of PubMed, Embase, and Web of Science databases was conducted to identify the eligible studies according to defined selection and excluding criteria and analyzed according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Fixed and random effects models were evaluated through the hazard ratios (HRs) and 95% confidence intervals (CIs) to estimate the overall survival (OS), recurrence-free survival (RFS), and progress-free survival (PFS).
Results: A total of 18 eligible studies including 1967 patients were analyzed for prognostic value. Totally 16 selected studies including 21 tests were relevant to the cervical cancer OS, 4 studies focused on RFS, and 1 study on PFS. The combined pooled HRs and 95% CIs of OS were calculated with random-effects models (HR = 1.64, 95% CI = 1.01-2.65, = .000). In the subgroup analysis for OS, there was no heterogeneity in MMP-2 (I = .0%, = .880), MMP-1 (I = .0%, = .587), and MMP-14 (I = 28.3%, = .248). In MMP-7 and MMP-9, the heterogeneities were obvious (I = 99.2% ( = .000) and I = 77.9% ( = .000), respectively). The pooled HRs and 95% CIs of RFS were calculated with fixed-effects models (HR = 2.22, 95% CI = 1.38-3.58, = .001) and PFS (HR = 2.29, 95% CI = 1.14-4.58, = .035).
Conclusions: The results indicated that MMP overexpression was associated with shorter OS and RFS in cervical cancer patients. It suggested that MMP overexpression might be a poor prognostic marker in cervical cancer. Research Registry Registration Number: reviewregistry 1159.

Background: Cervical cancer disparities persist among minoritized women due to infrequent screening and poor follow-up. Structural and psychosocial barriers to following up with colposcopy are problematic for minoritized women. Evidence-based interventions using patient navigation and tailored telephone counseling, including the Tailored Communication for Cervical Cancer Risk (TC3), have modestly improved colposcopy attendance.

Cancer, a complicated disease characterized by aberrant cellular metabolism, has emerged as a formidable global health challenge. Since the discovery of abnormal aldolase A (ALDOA) expression in liver cancer for the first time, its overexpression has been identified in numerous cancers, including colorectal cancer (CRC), breast cancer (BC), cervical adenocarcinoma (CAC), non-small cell lung cancer (NSCLC), gastric cancer (GC), hepatocellular carcinoma (HCC), pancreatic cancer adenocarcinoma (PDAC), and clear cell renal cell carcinoma (ccRCC). Moreover, ALDOA overexpression promotes cancer cell proliferation, invasion, migration, and drug resistance, and is closely related to poor prognosis of patients with cancer.

Human papillomavirus (HPV), a common sexually transmitted infection, includes over 200 types, some linked to genital warts and various cancers, including cervical, anal, penile, and oropharyngeal cancers. In Saudi Arabia, an estimated 10.7 million women aged 15 years and older are at risk of HPV-related cervical cancer.

Background: In Saudi Arabia, cervical cancer, frequently caused by human papillomavirus (HPV) infection, is a common cancer. The usual procedures for screening and diagnosing cervical cancer include Pap smears and HPV tests, even though they have considerable drawbacks, particularly for older women (> 60 years) who have limited access to or compliance with these tests. Urinalysis is a simple, noninvasive test that has been suggested as an alternative procedure.
