The progression from infection human papillomavirus laboratory high-risk HR strains of HPV to invasive cancer takes time, from 10 to 13 years or human papillomavirus laboratory longer. During this long natural history of precancer phase, the early detection and the local treatment of the screened population could stop the progression to invasive cancer and would make this human papillomavirus laboratory neoplasia a preventable disease. The highest incidence of invasive cervical cancer and the highest death rate due to this disease are encountered in low-resource countries, with no preventive care programs.

The key of success is an organized screening program that could dramatically reduce the incidence and mortality from cervical cancer through early detection and local treatment of early precancer lesions.

Cervical cancer screening in Romania: it is time to change

Progresia de la infecţia cu tulpini de HPV cu risc înalt până la cancer invaziv durează între 10 şi 13 ani. În cursul acestei lungi perioade de istorie naturală, detecţia precoce şi tratamentul local, într-o populaţie supusă screeningului, pot opri progresia către cancer invaziv şi pot transforma această infecţie oncogenă într-o boală ce poate fi prevenită.

Incidenţa cea mai mare a cancerului invaziv se regăseşte în ţările care nu au un program de prevenţie prin screening. Cheia succesului este organizarea unui program naţional de screening. România are cea mai mare rată de mortalitate prin cancer de col uterin din Europa şi nu are un program naţional de screening. Din acest motiv, România are nevoie urgentă de un program de detecţie a leziunilor precursoare ale cancerului colului uterin.

Cuvinte cheie cancer col uterin HPV citologie screening triaj Introduction Cervical cancer is one of the most frequent female cancers in the world, mainly in the lower-resource countries. Inaboutwomen were diagnosed with cervical cancer and 31, died due to this disease. A very convincing example is offered human papillomavirus laboratory the results of the national screening program in UK and Finland. Inthe national screening program for cervical cancer human papillomavirus laboratory introduced in UK.

More impressive figures are presented by Finland. Human papillomavirus laboratory, the screening program was based on exfoliative cytology Pap smear test. In the last de­c­ade, the traditional cytology screening was improved by liquid-based cytology.

Also, within the last decade, major improvements in cervical cancer prevention have been registered thanks to the introduction of HPV DNA detection tests.

The value of exfoliative cytology in the cervical cancer screening In recent years, a new technique was introduced, liquid-based cytology LBC.

This cancer has a delay in the diagnosis, being detected in more advanced stages, with a poor prognosis, partly reflecting the diagnostic delay.

Today, many countries are using HPV primary screening for the detection of precursor lesions of cervical cancer, clearly proving that HPV primary screening, maintaining a high sensitivity, could reduce the cost and the complexity related to co-testing 13, Most of the countries using HPV primary screening human papillomavirus laboratory human papillomavirus laboratory use routine co-testing, therefore reducing the cost of the screening while maintaining a high sensitivity.

Prospective randomized trials and even retrospective studies clearly showed that HPV primary screening has a higher sensitivity, when compared to cytology, in identifying earlier CIN3 and higher 9, One of the questions waiting for an answer is the selection criteria for HPV-positive women who should be referred to colposcopy.

Convincing results about how to build a national papilloma oncocytic program for the detection of cervical cancer, in a country that has not one yet, are offered by the results of the Athena study If cytology was negative, the woman was rescreened for HPV and cytology in one year.

Cytology strategy The cytology strategy was based on liquid-based exfoliative cytology examination.

It proved to be human papillomavirus laboratory best screening strategy at baseline, detecting with HPV primary strategy human papillomavirus laboratory with These better results were associated with a higher number of human papillomavirus laboratory.

HPV primary strategy has the advantage of detecting more cases at baseline when compared helmintii mixte hybrid strategy. Discussion There is a large number of prospective screening trials clearly proving that HPV primary screening is more sensitive than cytological screening 9,15,17, The advantage is clearly seen in glandular disease.

High-risk HPV primary test is an pastile pentru viermi pentru oameni noi test determined in central laboratories, with no need for technicians training, assuring human papillomavirus laboratory good quality control and the most credible results.

One potential excess of HPV primary screening is an increased number of unnecessary colposcopies.

These will human papillomavirus laboratory the cost of screening and will generate patient anxiety.

Human papillomavirus laboratory triage approach human papillomavirus laboratory include reflex cytology for all women positive for the other human papillomavirus laboratory HR-HPV Cobas test in order to select women who will be referred for colposcopy instead of sending all HR-HPV positive women.

Without a triage approach, HPV primary screening would recommend approximately a double number of colposcopies compared to cytology.

Conclusions and recommendations Romania has the highest rate of mortality due to cervical cancer in Europe and has no national screening program to prevent cervical cancer.

It is preventable through vaccination before starting sexual activity. The progression from infection with high-risk HR strains of HPV to invasive cancer takes time, from 10 to 13 years or even longer. During this long natural history of precancer phase, the early detection and the local treatment of the screened population could stop the progression to invasive cancer and would make this infectious neoplasia a preventable disease.

The opportunist screening human papillomavirus laboratory substantial in urban area, but does not cover the rural areas.

The 2nd edition of the European Guidelines for Quality Assurance in Cervical Cancer Screening established the principles of an organized screening program 6, These principles are: defining a target population women of years of age and screening intervals years if using cytology and years if using HR-HPV-test ; the use of a population-based registry and appropriate recruitment measures personal invitations, place and human papillomavirus laboratory where the screening test is taken ; the definition of the screening test; adequate facilities to perform this test; defined management algorithms, human papillomavirus laboratory the monitoring and evaluation of the process and of the impact of screening Mai multe despre acest subiect.
