"Obviously the tumor has been removed, but only a year later, why did I relapse?"
received a private message from a die-hard fan at the backend, saying that he had suffered from liver cancer for more than a year, and had surgery last year, and the doctor told him that the surgery It was a success, and he was very happy at the time, but he didn't expect that he would relapse in just one year. Recurrence after surgery is an experience of many cancer patients. Cancer is not easy to treat after just one treatment. Why does it recur?
1. How long does it take for the cancer to not recur after surgery, even if it is cured?
Cancer is a chronic disease that takes a long time to treat and is difficult to cure. When evaluating the effect of cancer treatment, doctors often do not say cure, but " clinical cure", which means that the cancer has not been completely cured. Instead, it is effectively controlled and relevant symptoms will not continue to appear, and the patient's quality of life has also been significantly improved.
If cancer patients want to achieve clinical cure, in fact, it not only depends on whether there is recurrence, but also needs to combine the following three points:
, Five-year survival rate
After cancer patients receive regular and effective treatment, their survival time can More than five years, and the cancer symptoms no longer occur within five years, then it is clinically considered that the cancer is basically cured. It should be noted that the five-year survival period of different cancers is different.
. Symptoms
Typical symptoms of general cancer include sudden weight loss, fever, lymphadenopathy, etc. If the cancer-related symptoms of cancer patients are reduced or disappear after effective treatment, it can also be used as a criterion for clinical cure of cancer.
. Quality of life
The ultimate goal of cancer-related treatment is to restore the patient's quality of life. If the patient's quality of life continues to improve after treatment, it means that the cancer is more likely to be cured.
2. Why does the tumor still recur even though it has been removed?
According to announcement data released by the my country Cancer Center in 2020, the five-year survival period of overall cancer in my country is now 40.5%, and about 60% of cancer patients have not achieved clinical cure after treatment.
from Zhou Rongrong, chief physician of the Oncology Department of Xiangya Hospital of Central South University , said that the current medical science has not yet concluded the mechanism of cancer recurrence or metastasis. Metastasis will inevitably lead to the inability of cancer patients to achieve clinical cure. Incomplete removal during surgery is a reason for cancer recurrence. However, there are also many cancer patients who have metastasized cancer cells during surgery; of course, there are also patients who have undergone clean surgery. , but if the carcinogens are not completely eliminated, the risk of recurrence will also increase.
Judging from the current relevant data, the following five cancers have the highest recurrence rates:
, Glioblastoma: The recurrence rate is close to 100%
A study in the "Journal of Neuro-Oncology" pointed out that glue Blastoma is a common brain tumor with a 100% recurrence rate. Glioblastoma spreads along the white matter in the brain in its early stages, making it difficult to determine the extent of the spread and making it impossible to completely remove it with surgery. In addition, glioblastoma grows rapidly, so the recurrence rate of patients is also high.
. Ovarian cancer: the recurrence rate is about 85%
Ovarian cancer is the cancer with the highest mortality rate among gynecological tumors. A study in "Expert Review of Anti-Cancer Treatment" pointed out that the recurrence rate of epithelial ovarian cancer reaches 85%.
In fact, the recurrence of ovarian cancer depends on the stage at diagnosis. The recurrence rate of ovarian cancer is 10% in stage I, 30% in stage II, 70% to 90% in stage III, and 90% to 95% in stage IV. It is usually treated early. The prognosis for patients with ovarian cancer is better, but because the early symptoms of ovarian cancer are insidious, many patients have already developed to the mid-to-late stage when diagnosed.
. Liver cancer: the recurrence rate is about 85%.
A study in the magazine "Surgery" found that the recurrence rate of hepatocellular carcinoma within five years has reached 85%!
Generally the factors that affect the recurrence of liver cancer are mainly tumor size, liver cirrhosis , nodule number, alcohol abuse, intrahepatic metastasis, vascular involvement, etc. The recurrence rate has a certain relationship with time, about 43% to 65% of liver cancer The patient relapsed within two years.
, Bladder cancer : The recurrence rate is about 80%
Bladder cancer is known as the "most expensive cancer". The main reason is that it is easy to relapse in the early stage, and subsequent treatments are many and expensive. Studies have shown that the recurrence rate of bladder cancer patients after surgery can reach more than 70%.
In a study of postoperative recurrence and risk factors of bladder cancer patients by a team of doctors from the Department of Urology, Zhongshan Hospital Affiliated to Fudan University, they divided bladder cancer patients into groups according to recurrence frequency and found that the group with high recurrence of bladder cancer had ht The proportion of ml1 smoking history is as high as 62.3%, and 1.9% of patients with recurrence and grade improvement within two years are smokers. In other words, smoking in bladder cancer patients will increase the recurrence rate and the degree of malignancy after recurrence will also increase.
3. Can cancer patients eat food? Experiments tell you the truth
The so-called hair food is a kind of food that is rich in nutrients or has stimulating properties. After eating, it may easily induce or even aggravate certain diseases or old illnesses. Crabs and meat are within the scope of hair growth. Many people believe that hair growth can cause tumor spread and recurrence. Is this true? Look at the experimental results.
In order to explore the effect of hair substances on the proliferation and apoptosis factors of liver cancer cells, researchers from Shandong University of Traditional Chinese Medicine conducted targeted in vitro experiments. They put cultured liver cancer cells into crab meat soup, pork soup and PBS. After culturing for 24 hours in the normal control group, results showed that there was basically no difference in the proliferation of liver cancer cells in the experimental group and the control group.
Sun Hongxin, chief physician of the Second Oncology District of Henan Provincial Hospital of Traditional Chinese Medicine, said that there is actually no scientific basis for the conclusion that "hair growth can cause cancer recurrence". Generally speaking, as long as cancer patients are not allergic to food and have no discomfort after eating, they can actually eat . However, the physical constitution of cancer patients is a little different. With the stimulation of radiotherapy, chemotherapy and drugs, the digestive function is very weak. In addition to strengthening the Regarding nutrition, you also need to pay attention to the appropriate amount, especially not to eat too many high-calorie, high-fat and spicy foods to avoid increasing the burden on the gastrointestinal tract and affecting recovery.
4. How to prevent recurrence and metastasis after cancer surgery?
. Maintain a good attitude
Many people feel scared when they hear about cancer, let alone cancer patients themselves. However, despite this, patients should still face it positively with a peaceful and optimistic attitude. This will help maintain the immune system and thus exert its full potential. Exudes anti-cancer activity and helps the body recover faster.
. Develop good living habits
Cancer patients themselves are physically weak, so they should pay attention to balanced nutrition in their daily diet, supplement adequate nutrition as much as possible, pay attention to a balanced diet, and avoid high-calorie, high-salt and spicy stimulation that are harmful to recovery. Unfavorable food. In addition, cancer patients should also pay attention to rest and not stay up late. Only by ensuring adequate sleep can they have stronger resistance to the disease.
. Regular review
Cancer cells are very cunning. Even after treatment, we cannot relax our vigilance. Therefore, cancer patients must strictly follow the doctor's instructions for regular review, so that they can understand the specific development of their condition at the first time and prevent the spread of cancer cells.
In this society where talking about cancer makes people panic, more and more people are suffering from cancer, and there is no cure for cancer, only "clinical cure". To achieve clinical cure, in addition to actively cooperating with doctors' treatment, maintain a good attitude and health Life style and diet are also necessary.#number one weekly# #大有knowledge#
