Chemotherapy methods for head and neck tumor include adjuvant chemotherapy, synchronous radiotherapy, palliative chemotherapy and neoadjuvant chemotherapy. 1. Adjuvant chemotherapy, mainly for patients with poorly differentiated or undifferentiated adenocarcinoma or squamous carcinoma, patients with high risk of metastatic recurrence in postoperative pathology, or patients accompanied by lymph node metastasis, adjuvant chemotherapy can be carried out to reduce the rate of recurrence in the later stage. 2. Simultaneous radiotherapy and chemotherapy, for patients who cannot be surgically resected, radiotherapy and chemotherapy are generally considered as simultaneous treatment, which has more prominent therapeutic effect, but is prone to cause adverse reactions. 3. Palliative chemotherapy, such as inoperable or recurrent head and neck tumors, palliative chemotherapy is considered to help prolong the survival cycle and improve the quality of life. 4. Neoadjuvant chemotherapy, which refers to chemotherapy for malignant tumors in surgery or radiotherapy, can shrink the tumor, control the whole body as metastatic foci, so that the original inoperable patients can get the chance of surgery. It is recommended that patients with head and neck tumors should go to regular hospitals for consultation in time, and choose appropriate treatment according to their specific conditions under the guidance of doctors.
