Jia Hongli: first check lung CT to see whether there has been lung metastasis. Patient: this has been done, there is no metastasis. Jia Hongli: the therapeutic effect of undifferentiated carcinoma of thyroid is far worse than that of papillary, follicular and medullary carcinomas, and the treatment of TSH inhibition is ineffective. The main cause of death is local tumor growth, followed by distant metastasis. Therefore, controlling the local lesions can improve the efficacy of treatment. No matter surgery, radiotherapy or chemotherapy, it is difficult to get good therapeutic effect when treating undifferentiated thyroid cancer alone, and the combination of surgery, radiotherapy and chemotherapy is the basic principle of treating undifferentiated thyroid cancer. At present, highly segmented radiotherapy combined with chemotherapy (Adriamycin, cisplatin, 5-Fu, etc.) still has certain efficacy, but we need to pay attention to its toxicity and complications. Ultra-fractionated radiotherapy, 5d per week, 2 times/d, 1.25Gy each time, total 40Gy, 2 cycles of chemotherapy before and 4 cycles of chemotherapy after radiotherapy, 60mg/m2 of adriamycin and 120mg/m2 of cisplatin each time, the main toxicities include severe pharyngo-esophageal inflammation and neutropenia, and the main cause of failure is distant metastasis. You should consult your surgeon and chemotherapist to see which part of the treatment process affects the pharynx and trachea, and find out the cause of the disease before treating the symptoms. If the lung infection is caused by poor immunity, you can only improve immunity and take anti-inflammatory drugs and oral cough medicine.
