Objective To report our experience in reconstruction with free jejunal flap for circumferential defect following resection of hypopharygeal and cervical esophageal carcinoma.Methods A retrospective analysis was conducted to evaluate the outcomes of reconstruction with free jejunal flaps for circumferential defects in 103 patients treated from Aug 2008 to Mar 2015.Among them,84 were hypopharyngeal carcinoma and 19 were cervical esophageal carcinoma;31 patients had total pharyngolaryngectomy,70 had total pharyngolaryngectomy and cervical esophagectomy and 2 had laryngeal preservation.All patients underwent bilateral neck dissection and 84 underwent retropharyngeal lymph node dissection.Results The 3 year overall survival rate was 51.6％ and disease-specific survival rate was 50％ The 5 year overall survival rate was 39.1％.No in-hospital death,one patient had unsalvageable flap failure and underwent second reconstruction with free jejunal flap.The success rate for the free jejunal flaps was 99％ (102/103).Pharyngocutanous fistula occurred in 3 patients and all healed with conservative treatment.Satisfactory oral intake was achieved in all patients.Conclusions Oncological and functional outcomes of reconstruction with free jejunal flap for circumferential defects of hypopharynx and cervical esophagus were satisfying.Multidisciplinary cooperation is helpful to improve surgical success rate.Free jejunal flap is an ideal method for reconstruction of circumferential hypopharyngeal and cervical esophageal defects after removal of tumor.

Objective: investigate the incidence of retropharyngeal lymph node (RPLN) metastasis and the risk factors for RPLN metastasis in hypopharyngeal cancer, and the relationship of planned dissection of the RPLN with the survival and tumor control rates in patients with hypopharyngeal cancer. Methods: A total of 203 patients with hypopharyngeal squamous cell carcinoma who underwent radical surgery as initial treatment from February 2011 to July 2015 were analyzed retrospectively. There were 167 cases of pyriform sinus carcinoma, 23 cases of posterior pharyngeal wall carcinoma, and 13 cases of postcricoid carcinoma. Results: The incidence of RPLN metastasis in HPC was 17.7%, with a highest rate of 43.5% in pharyngeal wall carcinoma. The incidence of RPLN metastasis in T3-4 pyriform sinus carcinoma was 18.3%, which significantly higher than 2.8% in T1-2 cases(χ²=5.360, P=0.020). The rate of RPLN metastasis was 23.8% in N2b-3 and 8.6% in N0-2a, with a statistically significant difference(χ²=7.637, P=0.006). There was no statistically significant difference in overall survival rates between patients with and without RPLN metastasis(P>0.05). Data were analyzed by SPSS 13.0 software. Conclusions RPLN metastasis is not rare in hypopharyngeal carcinoma. Planned dissection of the RPLN should be performed with the initial surgery in patients with advanced hypopharyngeal cancer, especially posterior pharyngeal wall carcinoma, T3-4 pyriform sinus carcinoma and staged N2b-3 disease, which can reduce the regional recurrence rate and provided with a better prognosis.

Objective: To evaluate the usefullness of flexible esophagoscopy and chromoendoscopy with Lugol′s solution in the detection of synchronous esophageal neoplasm in patients with hypopharyngeal squamous cell carcinoma (HSCC). Methods: A retrospective review of 96 cases with HSCC that received surgical treatment from March 2016 to March 2017 was accomplished. In these patients, the site of origin were pyriform sinus (n=75), posterior pharyngeal wall (n=11) and postcricoid (n=10). Esophagoscopy was prospectively performed on all patients before treatment for HSCC. All patients underwent conventional white-light endoscopic examination with Lugol chromoendoscopy and narrow band image. Suspicious areas of narrow band image or Lugol-voiding lesions were observed and biopsied. The treatment strategy of primary HSCC was modified according to the presence of synchronous esophageal squamous cell neoplasms by a multidisciplinary approach. Results: Ninety-six patients were enrolled (age ranging from 37-80 years). All patients did not have previous treatment.Histopathological analysis revealed middle to high-grade dysplasia in 5 cases, Tis cancer in 5 cases, cancer in 16 cases and inflammation or normal findings in the others. Four cases were treated with endoscopic submucosal dissection before hypopharygeal surgery, 3 cases with lower esophageal cancers were treated with gastric pull-up combined with free jejunal flap after total circumferential pharyngolaryngectomy (TCPL) and certical esophagectomy, and 14 cases were treated with TCPL, total esophagectomy and gastric pull-up. Conclusions Esophagoscopy is a feasible and justified procedure in HSCC cases as it enhances the detection of premalignant lesion or second primary cancer. Routine esophagoscopy for detecting synchronous second primary tumor should be recommended for patients with HSCC. The treatment strategy for primary HSCC is modified according to the presence of synchronous second primary tumor.

Objective: To investigate the key factors influencing the prognosis of hypopharyngeal carcinoma and the therapeutic methods improving the efficacy of treatments for hypopharyngeal carcinoma. Methods: Two hundred and sixty-four cases of hypopharyngeal squamous cell carcinoma treated from May 2010 to May 2015 were analyzed retrospectively. There were 211 cases of pyriform sinus carcinoma, 37 cases of posterior pharyngeal wall carcinoma, and 16 cases of postcricoid carcinoma. According to UICC 2002 criteria, 2 cases were for stage Ⅰ, 14 for stage Ⅱ, 32 for stage Ⅲ and 216 for stage Ⅳ. Postoperative circumferential defects existed in 112 (42.4%) cases, and 86 of them were reconstructed with free jejunum transplantation. Among all cases, 54 patients (20.5%) had the preservation of laryngeal functions after surgery and 210 patients (79.5%) with total laryngectomy; 238 cases (90.2%) underwent bilateral cervical lymph node dissection and 203 patients received posterior pharyngeal lymph node exploration and dissection, with positive metastases for posterior pharyngeal lymph nodes in 36 cases (17.7%). Eight cases with cervical lymph node metastasis extensively involving the soft tissue, prevertebral fascia or encases carotid artery received preoperative radiotherapy of 50 Gy. After surgery 13 patients received concurrent radiotherapy and chemotherapy, 337 underwent adjuvant radiotherapy with a dose of 50-60 Gy each, and 14 patients did not receive radiotherapy or did not completed their radiotherapy programs. SPSS 13.0 saftware was used to analyze the data. Results: All patients were followed up for more than 2 years. With Kaplan-Meier method, the 2-, 3- and 5-years survival rates were 69.6%, 62.8% and 51.3%, respectively. There were significant differences in 3-year survival rates between T1-2 group (75.5%) and T3-4 group (59.2%) (χ²=4.282 P=0.039), N0 group (81.6%) and N+ group (58.2%) (χ²=6.802 P=0.009), laryngeal functions preserved (81.8%) and unpreserved group (58.9%) (χ²=5.314 P=0.021). Multivariate Logistic regression analysis showed that cervical lymph node metastasis was an independent prognostic factor (P=0.027). The success rate of free jejunum transplantation was 98.8%. Local recurrence, cervical lymph node recurrence, second primary cancer, and distant metastasis accounted respectively for 11.2%, 18.8%, 12.5% and 45.0% of death cases. Conclusions The prognosis-associated factors for hypopharyngeal carcinoma should be taken into account, including the evaluation of the carcinogenesis of the mucosal area, early screening of premalignant lesion or second primary cancer in the esophagus and dissection of the posterior pharyngeal lymph nodes, which will help to improve the local control rate and recent survival rate in patients with hypopharyngeal cancer.

Objective: To evaluate the oncologic and functional outcomes of laryngeal squamous cell carcinomas treated by supracricoid laryngectomy. Methods: The clinical data of 134 patients with laryngeal cancer who underwent supracricoid laryngectomy with cricohyoidoepiglottopexy (CHEP) or cricohyoidopexy (CHP) between July 2005 and April 2014 at Shandong Provincial ENT Hospital were retrospectively reviewed. Ninety-one patients including 31 cases of stage Ⅰ, 36 of stage Ⅱ, 18 of stage Ⅲ and 6 of stage Ⅳ underwent CHEP and 43 patients underwent CHP. Two patients received CHEP due to recurrence after open surgery and laser surgery. Three patients received CHP due to the recurrence of disease after open surgery and postradiotherapy persistence of disease. The Kaplan-Meier method was used to calculate the 3-year and 5-year survival rates. The Chi-square test was used to compare the survival rates between different surgical procedures. Results: All 91 patients who underwent CHEP had successful removals of PEG tubes, and 88 (96.7%) of them had tracheostomy tube decannulation. Among 43 patients with CHP, 42(97.6%) cases removal of PEG tubes(97.6%), including and 40(93.0%) cases with tracheostomy tube decannulation. There was one patient with local recurrence in all cases. In CHEP group, 3-year local control rate was 98.2%; 3-year and 5-year overall survival rate were 94.5% and 93.9%, respectively. In CHP group, 3-year local control rate was 97.6%; 3-year and 5-year overall survival rates were 86.0% and 83.3%, respectively. Pharyngeal fistula appeared in 2 cases of CHEP group and 4 cases of CHP group, and all of them were cured by conservative treatment. Conclusion Supracricoid laryngectomy shows excellent oncologic and functional results for treatment of laryngeal cancer while maintaining laryngeal functions, especially in terms of local control rate and tracheostomy tube decannulation.
