Release date: 2014-07-14
As a high-end medical examination, PET-CT has become an anti-cancer physical examination that every country in the West must do. It has also become a "cancer artifact". The main purpose of PET-CT is not routine physical examination, and the guidelines for the use of the Chinese Medical Association are being developed.
It is understood that PET-CT is the abbreviation of positron emission tomography (CT), which can capture changes in biological metabolism in the early stage of tumor no morphological changes. It is understood that the positive rate of PET-CT examination is not less than 70%, that is, 70% of patients diagnosed by PET-CT. Some anti-cancer packages introduced by the medical examination institutions once burned PET-CT, and deified its function of discovering early cancer. The cost of a single inspection is more than 8,000 yuan, and it is sought after by healthy people with certain strength in the economy.
Zhu Xiaohua, director of the Department of Nuclear Medicine of Tongji Hospital, said that PET-CT has value in all stages of cancer diagnosis and treatment, but the main clinical use is not for physical examination, but for tumor staging and post-treatment evaluation, and identification of recurrence. It provides valuable help in the treatment of tumors, such as surgery, radiotherapy and chemotherapy.
Zhu Xiaohua also said that regular physical examination is not suitable for PET-CT. PET-CT is considered only if the routine physical examination reveals signs such as an increase in tumor markers or a high-risk group such as family history or exposure to carcinogenic factors.
Some experts believe that not everyone needs to do PET-CT examination, and even some cancers are not sensitive to this examination. The main role of this examination is the evaluation of the treatment of cancer comprehensive treatment, such as the efficacy before and after chemotherapy, whether there is recurrence, Transfer and so on. Using expensive PET-CT to screen tumors for normal people is not only a waste of resources, but also damage to the human body.
Prevention of cancer, PET-CT is useless, the key is to refuse smoking and second-hand smoke, do not eat waste oil, away from car exhaust, resist unhealthy food. Find a professional doctor to conduct targeted physical examinations for high-risk groups, such as gastrointestinal endoscopy, chest thin-slice CT as a routine physical examination for high-risk groups, routine abdominal, breast, gynecological, thyroid ultrasound, cervical smear, serum tumor markers Things and so on.
