What is the probability of recurrence of nasopharyngeal carcinoma

Tumors are very harmful and are prone to recurrence. Nasopharyngeal carcinoma is a common malignant tumor disease. It is undoubtedly a huge harm to the health of patients, because there is a high possibility of recurrence after the treatment of nasopharyngeal carcinoma patients, which poses a great threat to the health of patients. So what is the probability of recurrence of nasopharyngeal carcinoma patients?

Many times during the treatment of nasopharyngeal carcinoma, the recurrence rate is as high as 50% in our country. Cancer has the possibility of recurrence, and nasopharyngeal carcinoma is no exception. Radiotherapy is generally the first choice for nasopharyngeal carcinoma. The local recurrence rate after radiotherapy is about 50%, and the 5-year overall survival rate is between 30%. The survival rate of advanced patients is even lower.

What is the chance of nasopharyngeal carcinoma recurring? First of all, we also need to understand the cause of its onset. Experts say that radiotherapy kills cancer with first-order kinetics of exponential killing, that is, a radiotherapy dose can only kill a certain proportion of cancer cells in the tumor. According to this cancer killing law, no matter how many times the radiation is given, there will still be a small amount of cancer cells remaining. The number of cancer cells remaining depends on the size of the radiotherapy dose.

Secondly, the cause of nasopharyngeal carcinoma should be mainly chemotherapy for patients, because although there are a few cancer cells remaining after radiotherapy, they may not be detected clinically. Because a small lesion contains 106 cancer cells, the volume is only 1 cubic millimeter, and the weight is 1 mg. Does a small amount of cancer cells remaining after radiotherapy mean that it will definitely recur? The answer is no, because people have resistance, and the white blood cells in the body can recognize and kill foreign cells, aging cells or malignant cells. Moreover, the survival and division abilities of cancer cells that have been radiotherapy are very poor.

Thirdly, the recurrence of nasopharyngeal carcinoma also involves the strength of the antibody resistance. Experts say that if the antibody resistance is poor, the residual cancer cells can be killed and the disease will never recur. If the body's resistance is poor, the body can neither kill the residual cancer cells nor limit their growth, and the disease is prone to recurrence in the short term after radiotherapy. If the body's resistance is not strong enough to kill the residual cancer cells, but can inhibit their growth, the body cannot kill the residual cancer cells, and the residual cancer cells cannot grow. The body and the cancer cells are in a stalemate, reaching a temporary balance. The duration of this temporary balance depends on the strength of the two forces: the body's resistance and the growth of the residual cancer cells.

If the body's resistance decreases or the growth of residual cancer cells increases one day, recurrence will occur. Nasopharyngeal cancer patients with psychological disorders such as emotional instability, excessive doubts, and heavy mental burdens are prone to recurrence because psychological disorders can reduce the body's resistance through the nervous and endocrine systems.

What is the chance of nasopharyngeal carcinoma recurrence? In summary, this is the full explanation of the chance of nasopharyngeal carcinoma recurrence. Do you have a certain understanding of it? The chance of nasopharyngeal carcinoma recurrence varies from person to person. If you have any questions about the recurrence of nasopharyngeal carcinoma, you can directly consult an expert for understanding. I wish you a speedy recovery!
