Surgical risks and cure rates of nasopharyngeal carcinoma

Surgical risks and cure rates of nasopharyngeal carcinoma

1. The location of nasopharyngeal cancer is relatively hidden. The vertical diameter of the nasopharynx is 5.5-6.0 cm, which is only the size of a small matchbox. There are nerves entering and exiting the cranial cavity around it, and large arteries, veins and lymphatic tissues on the side walls. It is difficult to imagine performing radical surgery in this tiny place, not to mention the risk of damaging important surrounding structures.

2. It is believed that most drugs used in chemotherapy are cytotoxic drugs.

3. The first treatment for nasopharyngeal carcinoma is radiotherapy. Surgery is not the first treatment method. If localized lesions in the nasopharynx do not disappear or recur after radiotherapy, surgery can be performed. If there are metastatic lymph nodes in the neck, neck lymph node dissection can be performed.

What does positioning before radiotherapy for nasopharyngeal carcinoma mean?

Radiotherapy is the main treatment for nasopharyngeal carcinoma. Simple radiotherapy is sufficient in the early stage, while combined radiotherapy and chemotherapy are required in the middle and late stages. Radiotherapy positioning refers to the judgment of the depth of the tumor before tumor treatment. It also needs to be determined by B-ultrasound, X-rays and other examination methods, so as to kill tumor cells. Radiotherapy positioning refers to the judgment of the depth of the tumor before tumor treatment.
