Rectal cancer is a common malignancy and is treated with surgery, radiotherapy, and chemotherapy. Among them, radiotherapy is one of the important means for the treatment of rectal cancer. So, how is radiotherapy treatment for rectal cancer performed?
First, a pre-radiation evaluation is required. Evaluations include pathological evaluation, imaging evaluation, and clinical evaluation. Pathological evaluation refers to the determination of the type, grade, and stage of rectal cancer by means of biopsy. Imaging evaluation refers to the determination of the size, location and extent of the tumor through imaging examinations such as CT and MRI. Clinical evaluation refers to the determination of a patient's physical condition and treatment options through physical examination and medical history.
Next, the radiation regimen needs to be determined. The radiotherapy regimen includes radiotherapy dose, radiotherapy method, and radiotherapy duration. Radiation dose refers to the dose of radiation irradiated and is generally determined based on factors such as the size, location and extent of the tumor. There are two types of radiotherapy: external radiation (external irradiation), which refers to the irradiation from outside the body, and internal irradiation (internal irradiation), which refers to the placement of a radioactive source in the body for irradiation. The duration of radiotherapy refers to the duration of radiotherapy, which is generally determined by the dose of radiotherapy and the type of radiotherapy.
When administering radiotherapy treatment, the following points need to be noted. First of all, it is necessary to protect normal tissues and reduce the damage to normal tissues caused by radiation. Secondly, it is necessary to pay attention to the side effects of radiotherapy, such as nausea, vomiting, diarrhea, etc., and take timely measures to alleviate them. Finally, regular follow-up is required to observe the treatment effect and side effects, and adjust the treatment plan in time.
In conclusion, radiotherapy for rectal cancer is an effective treatment, but it requires adequate evaluation and determination of appropriate treatment options, while paying attention to protecting normal tissues and reducing side effects. #头条创作挑战赛#
