The doctor told me to do chemotherapy first to shrink the tumor and then have surgery.When it comes to chemotherapy, many people may feel that chemotherapy is more horrible than cancer itself, especially after experiencing the death of a loved one after chemotherapy.Some people say that chemotherapy can not cure cancer, but also make patients worse. What is the truth?First, chemotherapy does not cure cancer, but also makes patients worse?We all know that chemotherapy is a way to treat cancer, but how does chemotherapy work?Chemotherapy is a systemic treatment that uses chemicals to fight cancer.In chemotherapy, drugs quickly enter the body and spread throughout the body, killing not only local tumor cells but also those that have metastasized far away.Chemotherapy is superior to surgery and radiation therapy, and generally improves five-year survival and prolongs survival.Zhang Xiaotian, chief physician of the department of oncology at Peking University Cancer Hospital, said chemotherapy has different effects on different types of cancer. Some types of cancer are highly sensitive to chemotherapy, such as breast cancer and lymphoma. The 5-year survival rate of patients with these types of cancer can be greatly improved after chemotherapy.For gastric cancer and other moderately sensitive tumors, chemotherapy can effectively reduce the recurrence rate and prolong life.Two, did cure what side effect can there be, can disappear?Because chemotherapy is systemic, the drugs can kill normal cells as well as cancerous ones, a common side effect of the drugs.But most of the side effects of chemotherapy are temporary and generally go away after chemotherapy, although in some cases they can have long-term and even lifelong effects.According to Wang Jing, a breast surgeon at the Cancer Hospital of the Chinese Academy of Medical Sciences, short-term side effects that can be relieved after chemotherapy are usually called short-term side effects, including hair loss, nausea and vomiting, oral ulcers and bone marrow suppression.The extent of these side effects, and how long they last, depends on how the chemotherapeutic drugs are used and how they are dealt with.Patients with symptoms should not be alarmed, but should seek medical attention as soon as possible.Adverse effects that may persist after chemotherapy, often called long-term side effects.Long-term side effects are rare and do not occur in every patient.Common long-term side effects include infertility, osteoporosis, and heart damage.If there are symptoms of long-term side effects, go to the hospital in time for medical treatment, follow the doctor’s advice to adjust, reduce the impact of side effects.Three, cancer patients can withstand how many times of chemotherapy?In front of the introduction of chemotherapy is a systemic treatment, then why can not cure chemotherapy, but also more cycles?This is because chemotherapy drugs follow the law of “first-order kinetics” to kill tumor cells, that is, to kill a certain amount of tumor cells with a certain amount of drugs.Because the body cannot withstand too many drugs at a time, it needs multiple cycles of chemotherapy to kill more tumor cells and achieve a better therapeutic effect.Some adverse reactions after chemotherapy usually occur 7-14 days after administration, if chemotherapy at this time will increase the harm to the human body.For this reason, doctors generally use a two-week interval regimen, usually a 21-day regimen.He Shaohua, deputy director of precision Medicine Center of Huaihua Cancer Hospital, explained that chemotherapy, as a basic means of treating tumors, cannot be used in large numbers and indefinitely.Due to tolerance, toxic reactions and other problems, patients can usually only tolerate 6-8 times of chemotherapy at each stage, and most patients have to stop after more than 6 times of chemotherapy because the toxicity of chemotherapy cannot be sustained.Chemotherapy is after all a kind of treatment that has side effect, cancer patient money spent, sin also suffered, how can ability judge whether chemotherapy has effect?Four, how to judge the effect of chemotherapy?1, have the symptoms of the disease eased?The most direct manifestation of the effect of chemotherapy is the reduction of symptoms caused by the tumor.For example, patients with lung tumors often have difficulty swallowing due to compression of the esophagus. If chemotherapy works, the symptoms of dysphagia can be relieved.However, this is only an auxiliary judgment method.2. Have tumor markers decreased?A simple and convenient blood test can tell how tumor markers change before and after chemotherapy to determine whether chemotherapy is effective.The more tumor markers decreased after chemotherapy, the better the chemotherapy effect was.If the level of tumor markers is within the normal range with little fluctuation, a comprehensive judgment should be made in combination with other examinations.3. Has the tumor shrunk in the body?After chemotherapy, b-ultrasound, CT and other imaging examinations can observe whether the tumor is small, and see whether there are new tumors.RECIST (solid Tumor efficacy evaluation criteria) is used as a reference to determine whether the disease is in remission.Because of the lack of understanding of chemotherapy, many people have misunderstandings about chemotherapy.In fact, chemotherapy is not so terrible, but a routine and effective means of treating cancer.When you find something wrong, go to the regular hospital in time and trust the doctor to cooperate with the treatment, which is the key to cure the condition.Reference: [1] “Chemotherapy survival rate at 5 years: 2.3%?” “Chemotherapy is useless” Stems from deep public misconception.Guangming Daily.2016-12-22[2] “Side effects of chemotherapy and when it is needed”.Doctor’s Note.
