Cervical cancer vaccine is expected to be available during the year

Nanjing Gulou Hospital, Jiangsu Maternal and Child Health Hospital, Nanjing Maternal and Child Health Hospital and many other hospitals held large-scale free clinic activities for female friends. Experts on the clinic said that the onset of cervical cancer is very young. Cervical cancer vaccines can prevent cervical cancer to a certain extent. Mainland cervical cancer vaccines are expected to be available within the year.

The prevalence of cervical cancer is clearly young. Professor Hong Ying, director of gynecology at the Nanjing Gulou Hospital, said that the age of onset of cervical cancer is 40-50 years old, but in recent years, clinical chiefs Cheng Wenjun and You Zhixue have also told reporters that clinically One obvious feeling is that the incidence of cervical cancer has increased significantly in the past two years. Women and children in the province are required to open 10 cervical cancer operations a week, and the number of cervical precancerous lesions handled in one year is also about 500 cases.

The two youngest doctors of the Jiangsu Provincial People’s Hospital who had attended the cervical cancer were the youngest only 20 years old. Some of the 25-year-olds were out of college for a few years and found that cervical cancer was already advanced. Among the cervical cancer patients admitted to the Gynecology Department of Drum Tower Hospital, the youngest was only 17 years old. In fact, it takes about 10 years from the precancerous lesion of the uterine cervix to the cancer. If it can be detected in time, it is entirely possible to block the occurrence of cancer.

Cervical Cancer Vaccine is expected to be told at the end of the year that the cervical cancer is mainly related to HPV (high risk human papilloma virus) persistent infection. HPV virus is not far away from ordinary people, 80% of women will be infected with HPV virus in their lifetime, but only 25% of precancerous lesions. Inoculation of HPV vaccine is an effective preventive measure. It is understood that cervical cancer vaccine has been listed in the United States, Britain, Australia, Hong Kong and other countries and regions. According to Professor Hong Ying, director of Obstetrics and Gynecology Department of Nanjing Drum Tower Hospital, the end of this year, cervical cancer vaccine for HPV infection is expected to be listed in the mainland.

However, Dr. Yan Yanjing, outpatient department of Nanjing Maternal and Child Health Hospital, also reminded that the current HPV vaccine is mainly divided into two types, preventive and therapeutic. The clinical (http://) is mainly used for preventive vaccine, and the therapeutic vaccine is Clinical effects are still being studied (http://). If the vaccine is already infected with the type of HPV included in the vaccine, then the preventive vaccination is equivalent to “repairing the sheep”, which has limited significance. Therefore, the World Health Organization believes that the population that can obtain vaccine protection is between 9 and 26 years of age; the optimal age for vaccination is between 11 and 12 years old, or before sexual activity occurs.

Vaccination can't be ignored. Is it safe to screen for vaccination? Min Yanjing said that there are many types of HPV viruses, of which Types 16 and 18 are the most common and cause about 70% of cervical cancer. So the only two types of “mainstream” classifications are currently used in the world, but there are also a large number of Chinese, 58, 32, and 33 equally divided. In other words, vaccination does not work if the infection is of types 16 and 18.

Cheng Wenjun, chief physician, suggests that before the spread of the vaccine, the prevention of cervical cancer must first change the bad sex lifestyle and regularly visit the hospital for screening of precancerous lesions. After years of publicity and education, most people are more receptive to cervical smears. In fact, the most recommended by the medical community is the liquid-based cytology test of cervical cancer (that is, the TCT combined with virus testing).

According to statistics from the Drum Tower Hospital, 50,000 people with an opportunity to screen for abnormal TCTs in the last 3 years accounted for 5.4%. Cheng Wenjun said that if both the cervical smear and the virus test are negative, then the person being examined is relatively safe, and the relevant screening may not be done within three years.
