How long can colon cancer survive without surgery and chemotherapy and recurrence

There is no need for chemotherapy after colon cancer surgery, and the so-called colorectal cancer is divided into colon cancer and rectal cancer, collectively referred to as colorectal cancer. Whether chemotherapy is done after bowel cancer surgery is related to the stage of the tumor. In the early stage of bowel cancer, cancer cells have not penetrated the intestinal wall and lymph nodes have not metastasized, and the ** rate of postoperative patients can reach more than 80%, so there is no need for chemotherapy and radiotherapy, only regular observation is required.

In the relatively advanced stage of bowel cancer, where cancer cells have penetrated the intestinal wall or lymph nodes have metastasized, the five-year survival rate of postoperative patients may only be 40%-50%, so adjuvant chemotherapy is needed to improve their survival rate, and the survival rate can be increased by 10-15%.

Chemotherapy is not required for colon cancer surgery, and chemotherapy is usually not required after surgery for primary colon cancer, where the lesion is invaded in a superficial location, the tumor is confined to the submucosal or superficial muscular, and there is usually no lymphatic metastasis or distant metastasis. In stage II colon cancer, the lesion invades the deep muscle layer, subserosal layer, or even breaks through the serous layer, but there is no lymphatic metastasis or distant metastasis, and chemotherapy is usually not required after surgery; However, if the patient has high-risk factors, chemotherapy is indicated after surgery.

People with colon cancer do not necessarily need chemotherapy after surgery. Chemotherapy for colon cancer patients after surgery should also be judged according to the patient's condition. For early-stage bowel cancer, which is technically known as stage 1 bowel cancer, postoperative chemotherapy is not given after surgery.

For stage II and stage III bowel cancer, which is severe and special, adjuvant chemotherapy after surgery is still necessary.

Some colon cancer patients require chemotherapy after surgery. There are also some early-stage colon cancers that do not require chemotherapy after surgery, and only need regular follow-ups.

Whether colon cancer patients need chemotherapy after surgery mainly depends on the stage of colon cancer. If colon cancer is in stage I and stage II according to the international TNM staging criteria, there are no high-risk risk factors, and there is no lymph node metastasis, postoperative adjuvant chemotherapy is not required after surgery. At this time, it is only necessary to advise the patient to have a follow-up examination every 3 to 6 months.

Whether chemotherapy is required after colon cancer surgery depends on the postoperative pathology report. The postoperative pathology report will show several indicators of judgment.

First, the depth of invasion of the tumor. If the depth of invasion is shallow, chemotherapy is not required, and if the depth of invasion is deep, chemotherapy is required.

Second, whether the lymph nodes have metastasized. If lymph node metastases are present, postoperative chemotherapy is usually required.

At the same time, patients should do genetic testing related examinations, such as microsatellite testing, to help judge and guide whether to do chemotherapy, and the selection of drugs, which will help prevent colon cancer from metastasizing.

Hope solves your problem, hope.

Chemotherapy for colon cancer patients is generally determined by the location, size, and depth of invasion of the tumor. 1. If the tumor is found to be large before surgery and it is difficult to resect the tumor, the tumor can be reduced by chemotherapy before surgery. 2. After surgery, if the tumor is in the middle and advanced stages, chemotherapy can also be carried out, which can reduce the probability of tumor and ensure the quality of life of patients; 3. If the patient is initially diagnosed with an advanced tumor, the doctor will perform a combination of radiotherapy, chemotherapy, targeting, and immunity to control the patient's symptoms as much as possible.

Is chemotherapy necessary after colon cancer surgery? I think chemotherapy should be done in most cases, but the duration of chemotherapy varies depending on the severity of the disease. For lesions detected early to superficial disease, surgery can be performed without chemotherapy.

Colon cancer. After surgery. Is chemotherapy necessary? I. Personally, I feel that chemotherapy should be necessary. He's a colon, after all. It's not the same as cancer in the internal organs.

In the early stage of colon cancer, there can be no symptoms, and in the middle and late stages, it can be manifested as abdominal distension and indigestion, and then there is a change in bowel habits, abdominal pain, mucus stool or mucobloody stool.

It mainly depends on the stage of colon cancer.

My father had colon cancer surgery in November 2011 and did not have chemotherapy. Examination in June this year: CEA is 178, everything else is fine, but today the CEA is more than 300, and the index of the gastrointestinal tract is also 10 times higher, and it has metastasized to the liver, with 4cm by 5cm.

Q: He is 81 years old this year, he doesn't want to do chemotherapy, he is very weak now, how long can he last just by looking at Chinese medicine?

If you recover well and you can achieve a 5-year survival rate, you can go to LNZL-BIO

At present, the overall survival rate of colon cancer after surgery can reach about 50% after 5 years. How long colon cancer can survive after surgery is mainly affected by the stage of colon cancer, pathological classification and postoperative adjuvant effect. For patients with early colon cancer or even carcinoma in situ, if they can be detected in time and given the best surgical resection, patients can achieve long-term survival, such as 10 years, 20 years, and may even reach a similar survival period to normal people.

For colon cancer patients with undifferentiated carcinoma, tumor invasion of the serous layer, obvious regional lymph node metastasis or distant metastasis, even if surgery and postoperative chemotherapy are performed, there is a possibility of death** and metastasis within 1-3 years after surgery. However, palliative surgery or short-circuit surgery to resolve obstruction can sometimes only improve the patient's quality of life, but cannot prolong survival, and the patient may die within six months to one year after surgery.

It's hard to say, depending on the condition, it can be traditional Chinese medicine to control the condition and prolong survival.
