The radiation of cancer of colon is treated, treated _'s treatment of the way
Though it is a main means to form rectal cancer treatment that surgery is excised, some recurring rate after simple surgery is relatively high, most part recurs and takes place in the pelvis, so tumour is invaded around the rectum the soft tissue is that an operation can't be excised completely. So pelvis radiotherapy is to remove the only effective method suitable for selecting for use that these cancer cells are deposited. The intersection of cancer of colon and patient and postoperative radiotherapy show the result to skill. The radiotherapy is only suitable for the radiotherapy in the skill of the patient of cancer of colon.
(1) Radiotherapy scheme of cancer of colon
1.Effecting a radical cure radiotherapy: It is only suitable for the special and sensitive patient of a few early patient and cell type to kill tumour cells completely through radiotherapy.
2. The radiotherapy to the ill: With the purpose of lightening symptom. Suitable for the condoning treatment of stopping the pain, arresting blood, reducing the secretion, narrowing tumour, controlling tumour etc..
3. Radiotherapy, surgery complex treatment, two kinds of treatment means of surgery and radiotherapy of planned integrated application.
(2) Radiotherapy way of cancer of colon
1. The radiotherapy before the skill: Radiotherapy had the following advantages before the skill, activity of cancer cell subside, it sows scattered residual cancer cells to be difficult to survive make operation. To enormous and fixed, estimate that excises cancerous swelling with difficulty, radiotherapy can make the body of tumour dwindle in front of the skill, thus improve the excising rate. It shows to radiate biological research, when the blood support or support oxygen to reduce, the cancer cell is relatively postoperative high to the sensitiveness of the radioactive rays before the skill.
Radiotherapy should know the dosage strictly before the skill, with the medium-sized dosage (3500- 4500cGY) Should,not only increase operation complication, but also can improvement operation curative effect.
2. Postoperative radiotherapy: Postoperative radiotherapy has the following advantages: Find, after excising and sending tumour originally, the position to remaining tumour carries on marks, makes a reservation according to the operation, thus make, shine position may accurate, shine, have alternative, have better results. Send tumour excise, originally, tumour load reduce notably, help, improve residual the intersection of cancer and effect on the radioactive rays.
3. The radiotherapy in the skill: There is residual cancer on doubting in the skill and can't excise the place completely, carry on once heavy dose of and shine with thread.
