How many oral medicines are there for rectal cancer

Rectal cancer is caused by the malignant transformation of rectal tissue cells. The cause of rectal cancer is still not very clear, and its onset is related to social environment, eating habits, genetic factors, etc. Rectal polyps are also a high-risk factor for rectal cancer. So how many oral medicines are there for rectal cancer? The most commonly used oral medicines for rectal cancer are Xeloda, Uracil Tegafur Tablets + Calcium Folinate. The way of taking medicine is different for different treatment purposes. The following are three ways to take Xeloda.

The first method is preoperative radiotherapy combined with oral chemotherapy drugs: taking capecitabine tablets before surgery can improve the effect of radiotherapy. From the first day of radiotherapy, start taking oral chemotherapy drugs. Take it for a total of 5 weeks, 5 days a week, which is a 5×5 plan. Patients can imagine that they are still office workers, who need to go to work from Monday to Friday and rest on weekends. The same is true for oral chemotherapy drugs, take them for 5 consecutive days and rest for 2 days. This is easier to remember. The radiotherapy time of each hospital is different in the morning, noon and evening, but oral medications should still be taken once in the morning and evening.
The second method is to combine intravenous chemotherapy: intravenous chemotherapy for 1 day, oral chemotherapy for 2 weeks, and rest for 1 week. Oral chemotherapy for 2 weeks means taking it continuously without rest in between.
The third method is to take chemotherapy drugs orally alone. It is suitable for older patients who cannot tolerate chemotherapy. You can try taking it in small doses at the beginning, and then increase it to the regular dose. Although this method takes a long time to take the medicine, it is easier for patients to tolerate it. The specific method is to take oral medicine for 2 weeks, stop for 1 week, and then continue to take it, and repeat this cycle for half a year (before and after surgery).
