It was observed that in every age group more than 50% of women were estimated to have developed CIN within 24 months of recorded onset of persistent HR-HPV infection, with at least 30% of women in each age group probably developing CIN within 12 months.
In our cases, we had a rapid development of high-grade lesions; in fact, the cases of CIN3 and carcinoma occurred within 24-36 months of follow-up to which the women were undergoing for persistent HPV CIN1.
These are pre-cancerous changes within the cervical epithelium (lining cells of the neck of womb). There are three grades of CIN (CIN1,2&3) and even CIN3 starts 10 years before cervical cancer.
CIN 3 is usually caused by certain types of human papillomavirus (HPV) and is found when a cervical biopsy is done. CIN 3 is not cancer, but may become cancer and spread to nearby normal tissue if not treated.
In a meta-analysis of 36 studies involving 3,160 women with CIN2 who were actively monitored for at least 3 months, 50% of the lesions regressed spontaneously, 32% persisted, and just under one in five (18%) progressed to CIN3 or worse within 2 years.
With an hrHPV-negative LSIL test result, immediate CIN3+ risk is 1.1% and the 5-year cumu- lative risk is 2.0%,5 thus repeated testing in 1 year is recom- mended. With an hrHPV-positive test result, CIN3+ risk is at least 4.3% leading to a recommendation for colposcopy.
Thresholds are based on an estimated risk of CIN 3+ at the time of the abnormal cervical cancer screening result. As noted above, an immediate risk of CIN 3+ of 4% or higher leads to a management recommendation of colposcopy or expedited treatment.
Persistent infection with oncogenic human papillomavirus (HPV) is a prerequisite for the development of cervical intraepithelial neoplasia grade 3 (CIN3) and cervical cancer.
CIN 1 cervical dysplasia rarely becomes cancer and often goes away on its own. CIN 2 and 3 are more likely to require treatment to prevent cancer.
CIN does not cause any symptoms. You are not likely to find out you have it unless you have cervical screening. Screening uses tests to find abnormal changes and to check whether they should be treated.
A doctor explains that the chances of recurrence after treatment for CIN3 / CGIN are small. If CIN3 has been completely treated, in other words the abnormality has been removed in it's entirety with a zone of normal tissue around it, then the chances of it recurring are very, very small.
It has been estimated that the mean calculated time from infection to diagnosis of CIN3+ is 9.4 years (SD 4.1 years) and progression from CIN3 to invasive cervical cancer takes 10–20 years, depending on genotype [7, 8].
Somebody who has had CIN3 is at slightly higher risk of developing [cervical] cancer than somebody who has not had CIN3, and that's why we advise that these women should have smears every year for 10 years. And if the smears are normal, then they can return to the normal screening interval.
[38][39][40] Although not all HSIL (CIN3) lesions progress to invasive cancer, based on current evidence, HSIL (CIN3) lesions need to be treated to reduce the risk of further progression to invasive cancer.
Conservative management for women with CIN 3 during pregnancy is safe, but careful postpartum evaluation is necessary regardless of the route of delivery. However, there is some evidence that vaginal delivery may increase the rate of regression.
What is stage 0 cervical cancer? Some healthcare professionals use 'stage 0' to describe changes to cells in the cervix (abnormal cells). This can be confusing, as cell changes are not cancer. Stage 0 may also be called cervical intraepithelial neoplasia 3 (CIN3) or, less commonly, carcinoma in situ (CIS).
No, HPV (human papillomavirus) causes an infection that can lead to CIN, but they are not the same.
The standardised mortality ratio for cervical cancer or vaginal cancer for women treated for CIN3 was 2.35 (95% confidence interval 2.11 to 2.61), based on 3 160 978 women years and 355 cause specific deaths (table 1). There was a steep increase in mortality with increased age at diagnosis of CIN3.
Although LLETZ or a cone biopsy are the most common treatments for CIN2 and CIN3, occasionally, if a LLETZ or cone biopsy is not appropriate or the woman has additional gynaecological problems, a hysterectomy may be advised.
In one study, patients ages 20 to 24 years with CIN 3 were estimated to have a 0.5 percent progression rate to cancer in one year [25], which is substantially lower than the 10 percent per year risk for patients ≥80 years old.
(LIFE-time risk) A measure of the risk that a certain event will happen during a person's lifetime. In cancer research, it is usually given as the likelihood that a person who is free of a certain type of cancer will develop or die from that type of cancer during his or her lifetime.
The Tyrer-Cuzick model is a risk assessment tool that measures a person's probability of BRCA1 or BRCA2 mutations. By measuring these mutations, the tool estimates the likelihood of a woman developing breast cancer in 10 years or over their lifetime.
No significant association of height, weight, and BMI was found in patients with CIN1 and CIN2/3.
If you still have HPV after 3 years, you may need to have a colposcopy. You'll be asked to have a colposcopy. Information: HPV is a common virus and most people will get it at some point.
In general, it takes 10 to 20 years for CIN to progress to cancer, allowing a significant time period for detection and treatment. Progression from CIN to cancer requires persistent HPV infection.
