Clinic features of laryngeal carcinosarcoma and sarcomatoid carcinoma / 中华耳鼻咽喉头颈外科杂志

ABSTRACT

Objective@#To investigate the clinic feature, pathology, therapy and prognosis of the sarcomatoid caricinoma or carcinosarcoma of the larynx.@*Methods@#We reviewed the clinical records of 7 patients with laryngeal carcinosarcoma /sarcomatoid caricinoma who were treated at our hospital between June 1996 and August 2016. All patients were men (mean age, 65.9 years; range, 52 to 94 years). Among 7 patients, 6 had a history of smoking; 2 underwent radiotherapy; and 5 patients who didn′t undergo radiotherapy complained of hoarseness. The glottis was the most frequent site of involvement. Most tumors exhibited a polypold or pedunculated gross morphology. Among the 5 patients who didn′t undergo a radiotherapy, 2 were in stage Ⅰ, 2 in stageⅡ, and 1 in stage Ⅲ. The other 2 cases underwent surgeries and radiotherapy were staged.@*Results@#All 7 patients received surgeries, without lymph node metastasis. All the tumors were pathologically carcinosarcoma/sarcomatoid carcinoma. With immunohistochemistry examination, Vimetin was positive in all tumors, SMA positive in 3 tumors, S-100 positive in 1 tumors, but CD-68, HMB-45 or Myglobin was negative in all tumors. With follows-up from 3 months to 20 years, of 7 patients, 4 survived without recurrent, 1 dead, and 2 lost connection.@*Conclusions@#Both of the carcinosarcoma and the sarcomatoid carcinoma of larynx contain pathologically carcinoma and sarcoma. Surgery is the best choice for laryngeal sarcomatoid carcinoma, and these patients without a undergoing radiotherapy before surgery or these with little sarcoma in tumors show better prognosis.
