In this article we highlight three questions covered in the full review that pertain to the effectiveness of screening for reducing cervical cancer mortality and incidence as well as optimal timing and frequency of screening.

Eligible studies included women aged 15 to 70 years who were screened using conventional cytology, liquid-based cytology or human papillomavirus DNA tests. Relevance screening, data extraction, risk of bias analyses and quality assessments were performed in duplicate.

We conducted a meta-analysis using a random-effects model on the one body of evidence that could be pooled. Results From the 15, screened citations, 27 papers 24 studies were included; five older studies located in a United States Preventive Services Task Force review were also included.

A randomized controlled trial in India showed even a single lifetime screening test significantly decreased the risk of mortality from and incidence of advanced cervical cancer compared to no screening mortality: Cytology screening was shown to be beneficial in a cohort study that found testing significantly reduced the risk of being diagnosed with invasive cervical cancer compared to no screening risk ratio 0.

Pooled evidence from a dozen case—control studies also indicated a significant protective effect of cytology screening odds ratio 0.

This review found no conclusive evidence for establishing optimal ages to start and stop cervical screening, or to determine how often to screen; however the available data suggests substantial protective effects for screening women 30 years and older and for intervals of up to five years.

Conclusions The available evidence supports the conclusion that cervical screening does offer protective benefits and is associated with a reduction in the incidence of invasive cervical cancer and cervical cancer mortality.

Cervical cancer, Screening, Systematic review Background Cervical cancer is a treatable disease and tertiary interventions have contributed to reductions in mortality rates [ 1 ].

However, when downstream activities are combined with preventive efforts, there is greater impact in terms of lives saved. There is widespread acceptance that regular screening is the single most important public health strategy to reduce cervical cancer incidence and subsequent mortality.

Screening tests such as conventional cytology commonly referred to as the Pap smear are used to identify pre-cancers, which can be treated to prevent the occurrence of invasive cancer or allow the disease to be identified at an earlier stage, permitting more effective treatment.

The systematic review on which this paper is based provided evidence for the Canadian Task Force on Preventive Health Care to update their guideline regarding screening of average-risk women for cervical cancer [ 23 ].

Much of the recent research has focused on reductions in precursor cervical lesions, which are more common and present earlier outcomes for measurement during trials. However, evidence from a treated versus not-treated cohort study with year follow-up suggests a third of cases with precursor lesions will advance to invasive cancer [ 4 ].

Consequently, cervical cancer mortality and incidence of invasive cervical cancer were designated as the critical outcomes for this review.

To our knowledge, no published systematic review has addressed the question of screening effectiveness with these outcomes, and until recently there were no randomized controlled trials RCTs to inform decision-making.

Instead, ecological studies have been used to demonstrate that mortality from cervical cancer decreased as screening became more widespread [ 56 ].

Cervical cancer - an overview | ScienceDirect Topics The HR23 proteins were identified more than two decades ago as factors involved in initiation of global genome nucleotide excision repair GG-NER along with their interacting partner, xeroderma pigmentosum group C XPC protein. Because the HR23 genes encode proteins harboring ubiquitin-like UBL domains at their N-termini and two ubiquitin-associated UBA domains in their central- and C-terminal regions, the link between HR23 proteins and proteolytic degradation has been widely explored by several methods, including yeast two-hybrid screening and co-affinity purification.

However, higher level evidence is available. In this article we highlight three questions covered in the full systematic review: What is the effect of cervical cancer screening on incidence of and mortality from invasive cervical cancer?

How does varying the screening interval affect incidence of and mortality from invasive cervical cancer? How does varying the age at which screening is started or stopped reduce incidence of and mortality from invasive cervical cancer?

The PICOS population, intervention, comparator, outcome, study design framework for these questions was as follows: P asymptomatic women aged 15 to 70 years with a history of sexual activity, I conventional cervical cytology, liquid-based cervical cytology or human papillomavirus HPV DNA screening tests, C no screening, O cervical cancer mortality and incidence of invasive cervical cancer, and S RCTs and observational studies with comparison groups.

As above, results were limited to systematic reviews, RCTs and observational studies with comparison groups, involving asymptomatic women aged 15 to 70 years with a history of sexual activity, who were screened using conventional cytology, liquid-based cytology or HPV DNA tests.

These specific tests were purposefully selected as they are the most relevant screening modalities for the Canadian context, for which subsequent screening guidelines would be developed. The outcomes of interest were cervical cancer mortality and incidence of invasive cervical cancer.

Reference lists of on-topic systematic reviews were also searched to ensure all primary studies meeting our inclusion criteria were considered. Study selection and data extraction Pairs of reviewers screened all identified citations.

Any citation deemed potentially relevant was retrieved for full text review. Two reviewers independently assessed each full text article for eligibility. Disagreements were resolved through discussion.

For each included study, two reviewers independently extracted relevant outcome data and study details. Conflicts were resolved through discussion.

Baseline: percent of men aged 40 years and over had discussed the advantages and disadvantages of the prostate-specific antigen (PSA) test to screen for prostate cancer with their health care provider in (age adjusted to the year standard population).

Quality assessment Risk of bias assessments were completed in duplicate. This considers five criteria design, consistency, directness, precision, reporting bias to rate of a body of evidence as high, moderate, low or very low, indicating the assessment of the likelihood that further research will impact the estimate of effect [ 9 ].

After two reviewers independently assessed the evidence on the criteria, agreement was reached on the ratings and the overall quality of the summary statistics. Statistical analysis For the one included RCT we combined the cytology and HPV testing arms into a single screening group that was compared to the control group on the outcomes of cervical cancer mortality, incidence of all cervical cancer, and incidence of stage II or higher cervical cancer.

Most HPV infections cause no symptoms and resolve spontaneously.

In some people, an HPV infection persists and results in warts or precancerous lesions. The precancerous lesions increase the risk of cancer of the cervix, vulva, vagina, penis, anus, mouth, or throat. Nearly all cervical cancer is due to HPV with two.

A Pap smear (Papanicolau smear; also known as the Pap test) is a screening test for cervical cancer. The test itself involves collection of a sample of cells from a woman's cervix (the end of the uterus that extends into the vagina) during a routine pelvic exam.
