What can cervical TCT detect? Comprehensive analysis of cervical thin-layer liquid-based cytology
Cervical TCT (thin-layer liquid-based cytology) is an important technology widely used in cervical cancer screening in recent years. As the "gold standard" for early screening of cervical cancer, it is more accurate than the traditional Pap smear. This article will provide a detailed analysis of the types of diseases that can be detected by TCT examinations and the clinical significance of the examination results, as well as the hot health topics of recent concern across the Internet.
1. Core testing content of TCT inspection
| Test items | Specific content | clinical significance |
|---|---|---|
| Abnormalities of epithelial cells | Squamous epithelial/glandular epithelial lesions | Precancerous lesions warning |
| microbial infection | HPV, trichomonas, fungi, etc. | Identify the source of infection |
| degree of inflammation | Number and shape of white blood cells | Assess cervicitis status |
| cancerous cells | abnormal mitotic figures | early cancer diagnosis |
2. Grading interpretation of TCT results
| TBS diagnostic system | Chinese correspondence | Follow-up processing |
|---|---|---|
| NILM | No intraepithelial lesions seen | Routine follow-up |
| ASC-US | atypical squamous cells | HPV test |
| LSIL | low grade squamous epithelial lesion | colposcopy |
| HSIL | high grade squamous epithelial lesion | Treat immediately |
| SCC | squamous cell carcinoma | Oncology consultation |
3. Recent related health hot spots
1.HPV vaccine hot discussion: Free vaccination policies have been launched in many places, and experts suggest that TCT+HPV combined screening is more effective.
2.Cervical cancer younger trend: The latest statistics show that the proportion of patients under 30 years old has increased by 37% in five years.
3.AI-assisted diagnostic technology: Many hospitals have introduced artificial intelligence systems, and the TCT detection accuracy rate has increased to 98.6%.
4. Precautions for TCT inspection
| time requirement | Things to note | Special groups |
|---|---|---|
| menstrual cycle | Avoid menstrual period and 3 days before and after | Pregnant women need to be careful |
| Before inspection | No sex for 24 hours | Acute inflammation phase temporary |
| After inspection | There may be a small amount of bleeding | Severe bleeding requires medical attention |
5. Frequently Asked Questions
Q: Will TCT examination hurt?
A: Routine examination only causes slight discomfort, and sensitive people can choose a thinner special brush.
Q: What should I do if the test results are abnormal?
A: It needs to be combined with the HPV test results. Colposcopy biopsy is recommended for ASC-US and above, and conization treatment is required for HSIL.
Q: How often should I be reviewed?
A: For those over 30 years old, it is recommended to do it once a year. Normally, it can be changed to once every 2-3 years for 3 consecutive years.
6. Expert advice
1. It is recommended that sexually active women over 21 years old undergo regular TCT screening.
2. Regular examinations are still required after receiving the HPV vaccine. The vaccine cannot replace screening.
3. There is no need to panic when abnormal results are found. The cure rate for early lesions exceeds 90%.
98% of cervical lesions can be detected early through TCT examination, and combined with HPV testing, cervical cancer mortality can be significantly reduced. It is recommended that female friends establish a standardized screening plan to protect reproductive health.
