RESUMEN
Objective, To investigate the clinical features, pathological features, treatment methods and prognosis of 5 patients with sarcomatoid carcinoma of throat. Methods, The clinical data of 5 patients with sarcomatoid carcinoma of throat confirmed by pathology were retrospectively analyzed, and the relevant literatures were reviewed. Results, Among 5 patients with sarcomatoid carciroma of throat, 4 patients were male and 1 patient was female, with the onset age from 55 to 77 years old. Among them, 3 patients had a long-term smoking history and 2 patients had a long-term drinking history. The chief complaints of the patients were pharyngeal pain, foreign body sensation in the pharynx, hoarseness and dyspnea, etc. All 5 patients underwent electronic laryngoscope examination, and 1 case presented cauliflower mass, while the other patients presented smooth mass. CT examination was performed in 2 patients, and the mass showed soft tissue density shadow without bone destruction. All 5 patients received surgical treatment, including 2 cases of adjuvant radiotherapy after operation and 1 case of chemotherapy after operation. The postoperative histopathological examination and immunohistochemical staining results showed that the diagnosis of 5 patients was sarcomatoid carcinoma. The postoperative follow-up time was 1-36 months, and the follow-up rate was 100%, among 5 patients, 1 case survived and 4 cases died. Conclusion: Sarcomatoid carcinoma of throat has no specifically clinical characteristics, and mainly present polypoid growth and is easy to be misdiagnosed. Its malignant degree is higher than that of squamous cell carcinoma, and it is easy to relapse and metastasis in the late stage. Its prognosis is poor, the diagnosis depends on the pathological examination, and surgical resection is preferred.
