    Don't treat colorectal cancer bleeding as hemorrhoids

    Lin Lizhu said that for early detection of colorectal cancer, it is best for the general population to have colonoscopy at age 50, and for high-risk groups, it is recommended to have colonoscopy at age 40. Overweight, irregular life, long-term constipation, living in a high-incidence area of ​​colorectal cancer, patients with rectal polyps, patients with gastrointestinal cancer, patients with female reproductive system tumors, long-term ulcerative colitis, and colorectal cancer among immediate relatives Of people belong to high-risk groups.

    In some remote areas, colonoscopy is not available, and routine stool examination and digital anal examination should be done at least once a year. These two examinations are very cheap and can be used as a primary screening for colorectal cancer. Especially the latter, because half of the patients with colorectal cancer in China belong to rectal cancer, experienced doctors can find rectal cancer through digital anal examination.

    In clinical practice, many patients with hemorrhoids mistakenly regard bleeding caused by colorectal cancer as hemorrhoids bleeding, thus delaying the condition. Lin Lizhu reminded that bleeding caused by hemorrhoids is mostly bright red, bleeding after the stool, and can be self-healing; while bleeding caused by colorectal cancer is mostly mucus-like blood in the stool, which is easy to repeat. It is difficult for ordinary patients to distinguish, so it is recommended that patients with hemorrhoids with blood in the stool who have never undergone colonoscopy should undergo a colonoscopy to prevent gastrointestinal tumors from becoming a "fish through the net". The doctor who receives the consultation should also have the awareness of "no effort" and perform digital anal examination for the patient.

    Colorectal cancer requires comprehensive treatment + precision treatment

    Lin Lizhu introduced that the treatment of early colorectal cancer is mainly surgery, and there are multiple treatment methods for middle and late colorectal cancer such as chemotherapy, radiotherapy, targeted drugs, and traditional Chinese medicine. The current treatment concept is comprehensive treatment + precision treatment.

    At present, the most common gene research in colorectal cancer is the RAS gene, which can be divided into wild type and mutant type. Among patients with colorectal cancer, about half of the RAS genes are wild-type. For the treatment of targeted drugs, there is already some evidence that can benefit patients. For example, the multi-center randomized clinical Phase III TAILOR study just released by the 18th World Gastrointestinal Cancer Conference showed that the targeted drug cetuximab for the treatment of colorectal cancer combined with common chemotherapy regimens for gastrointestinal tumors can metastasize RAS wild-type Patients with sexual colorectal cancer bring significant survival benefits, said Professor Lin Lizhu, one of the leaders of the TAILOR study.

    Lin Lizhu added that TCM treatment can run through the entire process of colorectal cancer treatment. Once diagnosed, you can seek TCM treatment instead of treating TCM as the last "lifesaver". For patients undergoing surgery, radiotherapy and chemotherapy, the purpose of early intervention of traditional Chinese medicine is not only to reduce the adverse effects of these treatments, but also to resist recurrence and metastasis, and even plays a very important role in the maintenance treatment stage.
