Abstract:
Objective:To evaluate the oncologic and functional outcomes of postcricoid carcinoma treated by surgical treatment, and to summarize our clinical experience in surgical treatment and reconstructive techniques.Methods:Medical files of 45 patients were collected and retrospectively analyzed. The patients received surgical treatments between January 2010 and May 2017 in the Qilu Hospital of Shandong University, including 39 males and 6 females, the age ranged from 41 to 78 years old. T1, T2, T3 and T4 staging tumors represented respectively for 2,13,23 and 7 cases. And cervical metastasis was histologically identified in 33 cases (8 for N1 and 25 for N2). Advanced staging patients (10 in Stage Ⅲ and 30 in Stage Ⅳ) accounted for 88.9% of the cohort, while early staging cases (1 in Stage Ⅰand 4 in Stage Ⅱ) for 10.1%. All patients received cervical lymph node dissection. After tumor excision without compromising margins, hypopharyngeal functions were reconstructed by residual mucosa, pectoralis major myocutaneous flap, laryngotracheal tissue flap or gastric tissue flap, and laryngeal functions were reconstructed by epiglottis, sternohyoid myofascial flap or thyroid perichondrium. Survival rates were analyzed by the Kaplan-Meier method.Results:Postoperatively 23 patients received radiotherapy and 13 patients received chemoradiotherapy. All patients were followed up for more than 3 years. Total 3-year and 5-year survival rates were 60.5% and 49.0%, respectively. Patients obtaining the conservation of laryngeal functions accounted for 44% (20/45) of all cases. The neck lymph node positive rate was 73.3%(33/45), and log-rank test demonstrated that cervical lymph node metastasis was significantly associated with prognosis of patients (χ 2=4.364, P=0.037). Conclusion:Appropriate surgical approaches and excision methods and comprehensive application of flaps are critical to precise tumor excision and reconstruction of laryngeal functions, thereby improving the quality of life of patients with posterior carcinoma.
