Common treatment methods of colorectal cancer

Colorectal cancer is a common malignant tumor, is collectively referred to as colorectal cancer and colon cancer, multiple in the elderly. 2007 new cases of 1.2 million worldwide died from colorectal cancer 630,000, and the incidence rate, the annual increase of 2%. More and more people concerned about the diagnosis and treatment of colorectal carcinoma.

Diagnosis of colorectal cancer

Director of Professional Committee of the National Colorectal Cancer Professor Wan Desen pointed out that the diagnosis of colorectal cancer are mainly the following methods:

1, rectal rectal examination, in China more than 50% of colorectal cancer occurred in the rectum, while 80% belong to middle and low rectal cancer, rectal digital examination can check out,

2, stool examination: fecal occult blood test in the diagnosis of the disease Although there is no specific, but the method is simple and can be used as screening tools census, or can provide clues to early diagnosis.

3, barium enema X-ray examination: lesions in the sigmoid colon or higher position of the previous paragraph are required to carry out X-ray barium enema examination. Ordinary barium enema X-ray examination of the smaller easily missed diagnosis of colorectal cancer, the best use of air-barium double contrast, can improve diagnostic accuracy of radiological and shows the location and extent of cancer.

4, the most specific method is the large intestine endoscopic examination, commonly known as colonoscopy, is divided into colonoscopy and sigmoidoscopy:

Colorectal cancer

Experts advise patients, at this stage colorectal cancer with surgery as the first choice, supplemented by radiation therapy, chemotherapy drugs and Chinese medicine treatment; the point out that the practice of medicine in early colorectal cancer using endoscopic resection, but also to achieve better efficacy. As for how to choose the best option to be based on different clinical and pathological staging. The key lies in the treatment of colorectal cancer early detection and early diagnosis.

1, surgical treatment: The only cure colorectal cancer is early excision. Exploration has been found in cancer metastasis, but the song can still be free when the intestinal lesions, in principle, that of colorectal cancer should be removed in order to avoid future occurrence of bowel obstruction; the other hand, cancer often erosion, oozing, or accompanied by secondary infection after excision of the body can improve the situation. To have a broad cancer metastasis, such as the intestines can no longer lesions removed, it should be built palliative procedures such as fistula, or shortcuts.

2, Chemical drug therapy: Colorectal cancer after curative resection, there were about 50% of the cases of recurrence and metastasis, mainly before the surgery failed to find occult metastases or the surgery failed to remove the lesion completely. Therefore, abdominal surgery prior to systemic chemotherapy may be provided through the intestine or chemotherapy, can prevent the cancer cell proliferation, destruction and elimination of cancer cells. Continued after chemotherapy, there is likely to increase 5-year survival rate after radical resection.

3, radiation therapy: efficacy is still not satisfied. Some people think that: ① preoperative radiotherapy can reduce the tumor size and improve resection rates, reduce the regional lymph node metastasis, patients in the cancer cells spread and local recurrence; ② postoperative radiotherapy: A case of radical surgery if the tumor has penetrated the intestinal wall violations of local lymph nodes, lymphatic and blood vessels, or residual tumor after surgery, but no distant metastasis, and are advised to make post-operative radiotherapy; ③ radiotherapy: for advanced rectal cancer cases, with a small dose of radiation therapy, sometimes play a temporary remedies, analgesic effect.

4, other treatments such as cryotherapy, cryotherapy is used refrigerant liquid nitrogen, through the anus after the mirror has fully exposed the tumor, choose the size of shells ranging from the first contact-type frozen tumor tissue, which can effectively kill and destroy tumor tissue. In patients with unresectable advanced, when, where appropriate, can reduce patient suffering from for artificial anus, with the efficacy of chemotherapy can be satisfied. In recent years, biological treatment was also explored. With traditional Chinese medicine to surgery, radiotherapy, chemotherapy, more smoothly and improve effectiveness.
