If a man has not defecated for three days, the treatment options for colon cancer include radical surgery, palliative surgery, chemotherapy, radiotherapy, targeted therapy, etc., which should be chosen according to the specific conditions.
1. Radical surgery: if patients have not combined with acute intestinal obstruction and no distant metastasis is found after relevant examination, radical surgery can be considered after careful evaluation.
If the patient has already had acute intestinal obstruction and does not have the opportunity for radical surgery, stenting or stoma can be performed first to improve the intestinal obstruction, and then radical resection can be performed after the patient’s general condition improves.
2. Palliative surgical treatment: if the patient has extensive distant metastases, radical surgical resection is not possible. When the patient has acute intestinal obstruction and other serious complications, palliative surgical treatment can be carried out to improve the intestinal obstruction, reduce the pain of the patient as much as possible, and improve the quality of life.
3. Chemotherapy: chemotherapy includes preoperative neoadjuvant chemotherapy, postoperative chemotherapy, palliative chemotherapy, peritoneal hyperthermia chemotherapy, etc. Commonly used drugs include 5-fluorouracil, oxaliplatin, capecitabine and so on, and different chemotherapy modes and dosage regimens can be chosen according to different conditions.
4. Radiotherapy: similar to chemotherapy, radiotherapy can also be divided into preoperative radiotherapy, postoperative adjuvant radiotherapy, palliative radiotherapy, etc., which should be chosen after evaluation.
5. Targeted therapy: For patients who are already in the advanced stage of colon cancer, targeted therapy can prolong the survival period to a certain extent, and commonly used drugs include bevacizumab and cetuximab.
It is recommended to go to the hospital as soon as possible and ask the professional doctor to evaluate the condition and make a reasonable treatment plan.
