Colon cancer impacts much to patients. At present, surgeries, chemotherapies and interventional therapy etc. can advance patients’ living treatment and reduce impact on patients to make a better recovery and faster free from disease.
It emphasizes firstly resection. But pre-resection combined treatment like chemotherapy and radiotherapy has to be linked to increase resection rate and survival rate and lower recurrence rate after resection.
Metastasis and recurrence could occur to almost half of the patients after surgery. Patients in terminal stage and after resection except parts of those in early stage should go through chemotherapy. Chemotherapy is another important method.
1.Systemic intravenous combined chemotherapy.It is mainly based on 5-FU affiliated with conditioner, FH4 to enhance effect of 5-FU
2.Chemotherapy by oral.It mainly refers to prodrug like fluoropyrimidine, which after absorption, can change to 5-Fluorouracil via once or multiple metabolization for anticarcinoma. Chemotherapy by oral has high clinical effect, less side effect, convenience, and availability for out-patient treatment. It is beneficial for elder tumor patients and home chemotherapy, which makes it a new, affiliated therapeutic trend.
3. Interventional Therapy
Interventional therapy is a mini-invasive therapy performed under the guidance of medical imaging equipments. With a 1-2 millimeter incision, paracentesis can be performed with the lead of medical imaging equipment. Then a special tube, catheter or other sophisticated apparatus are introduced to inhibit the growth and spread of cancer cells, so as to cut off the tumor’s blood supply and reach the effect of local chemotherapy without any toxic side effects of chemotherapy. It has the following advantages:
Drugs are directly given to the tumor to cut off the blood supply and starve the cancer cells to death, so as to protect the normal tissues from the drugs.
2.Small Trauma, Quick Recovery
No operation. With a 2 mm incision, patients can restore to health quickly.
3.Few Side Effects
Interventional therapy overcomes the disadvantages and deficiencies of traditional chemotherapy. Drugs reach to the tumor are of high concentration, which bring few side effects and reduce patients’ suffering.
Patient’s survival time can be prolonged and live quality can be improved after taking interventional therapy.
Interventional therapy can be taken repeatedly because it is not restricted by the metabolism of cancer cell.
Interventional therapy usually adopts local anaesthesia, which avoids the limitation and risk of general anesthesia.
