miR-144-3p, a tumor suppressive microRNA targeting ETS-1 in laryngeal squamous cell carcinoma.

Regional lymph node metastasis and distant metastasis are critical in the prognosis of laryngeal squamous cell carcinoma (LSCC). This study investigated the roles of miR-144-3p and E26 transformation specific-1 (ETS-1) in the invasion and migration of LSCC cells. The effects of miR-144-3p and ETS-1 on FaDu and Hep2 cell growth, migration and invasion were determined.

[The clinical application of modified rhytidectomy incision in superficial parotid tumor surgery].

Objective: To evaluate the modified rhytidectomy incision in superficial parotidectomy.

Method: Thirty-five patients with superficial parotid tumor were included in this study. A modified rhytidectomy incision often used in facial plastic surgery was used for superficial parotidectomy and subtotal superficial parotidectomy with preservation of facial nerve and great auricular nerve.

Micro-ribonucleic acid expression profiling and bioinformatic target gene analyses in laryngeal carcinoma.

Abnormal expression of micro-ribonucleic acid (miRNA) might be clinically valuable as a biomarker or treatment target in the early diagnosis, treatment, and prognosis of tumors. However, little is known concerning abnormal miRNA expression of laryngeal carcinoma, one of the most commonly encountered head and neck tumors. Microarray analysis was used to obtain miRNA-expression profiles of ten pairs of freshly frozen laryngeal carcinoma tissue and surrounding normal tissue specimens.

[A comparison between endoscopic-assisted second branchial cleft cyst resection via retroauricular hairline approach and conventional second branchial cleft cyst resection].

Objective: To assess the feasibility, risks and advantages of endoscope-assisted second branchial cleft cyst (SBCC) resection via the retroauricular hairline approach (RHA) by comparing with conventional trans cervical approach.

Method: Using prospective clinical controlled study, in twenty five patients with SBCC, 13 cases underwent endoscope-assisted resection via the RHA, 12 cases underwent conventional transcervical approach resection. Preoperatively, the sizes, locations and adjacency of all lesions were evaluated by ultrasonography, CT or MRI.

[Meta-analysis on the risk factors for stomal recurrence after total laryngectomy].

Objective: To evaluate the risk factors of stomal recurrence in patients after total laryngectomy.

Method: A thorough literature search was performed among Wanfang database, Chinese Scientific Journals Database of VIP and pubmed database. Meta analysis was performed on a total of 2725 patients in 2 Chinese papers and 6 English papers which met the inclusion criteria.

Retrospective analysis of prognostic factors in 205 patients with laryngeal squamous cell carcinoma who underwent surgical treatment.

Objectives: To investigate the most important factors affecting the prognosis of the patients with squamous cell carcinoma (SCC) of the larynx.

Methods: Based on the clinical and follow-up data, 205 patients with SCC of the larynx receiving total laryngectomy, partial laryngectomy, or CO2 laser surgery in GuangDong General Hospital were retrospectively analyzed. A survival analysis was performed by the Kaplan-Meier method and a multivariable analysis of prognostic factors was carried out using the Cox proportional hazard model.

Supracricoid partial laryngectomy cricohyoidoepiglottopexy (SCPL-CHEP) versus vertical partial laryngectomy for the treatment of glottic carcinoma.

The study aimed to compare the survival rate and functional outcome of supracricoid partial laryngectomy cricohyoidoepiglottopexy (SCPL-CHEP) and vertical partial laryngectomy (VPL) in the treatment of glottic carcinoma. Thirty-nine patients underwent SCPL-CHEP and 45 patients underwent VPL between 2002 and 2007. Post-operative clinical staging were performed according to the UICC staging criteria (2002).

[Long-term outcome of CO₂ laser microlaryngoscopic treatment for laryngeal cancer].

Objective: To investigate the long-term outcome of CO₂ laser microsurgery for laryngeal cancer.

Methods: Seventy patients with laryngeal cancer were treated with CO₂ laser microsurgery. All patients were followed up for at least 36 months (36 - 108 months).

[A comparison between endoscopic-assisted submandibular gland resection via retroauricular hairline incision and conventional submandibular gland resection].

Objective: To assess the feasibility, the risks and the advantages of endoscope-assisted submandibular gland resection using a retroauricular hairline incision (RAHI) by comparing it with the conventional submandibular gland resection.

Methods: Twenty eight patients with benign lesions of the submandibular gland were included in the prospective clinically controlled study. Thirteen patients had endoscope-assisted resection using the RAHI approach and 15 cases had conventional transcervical approach resection.

[Selective neck dissection for treating recurrent branchial anomalies].

Objective: To evaluate the role of selective neck dissection in the treatment of recurrent branchial anomalies.

Method: The clinical data of 18 patients with recurrent branchial anomalies were retrospectively analyzed. In accordance with the embryologic and anatomic features of branchial anomalies, different types of selective neck dissection were applied.

[Preliminary experience with endoscope-assisted transoral excision of the submandibular gland].

Objective: To discuss the indications, risks and benefits of endoscope-assisted transoral approach to excise the submandibular gland.

Methods: A retrospective review of a series of 12 patients treated by endoscope-assisted transoral submandibular gland excision was carried out. Of the 12 patients, 8 were chronic sialoadenitis (2 cases with sialolith), 3 were pleomorphic adenoma, and 1 was cyst of submandibular gland.

[Diagnosis and treatment of congenital fourth branchial anomaly].

Objective: To discuss the anatomic features, clinical presentations, diagnosis, differentiations and treatments of congenital fourth branchial anomaly(CFBA).

Methods: The clinical data of 8 patients with CFBA were retrospectively analyzed.

Results: Of the 8 patients aging from 27 to 300 months (median age: 114 months), 4 male and 4 female; 3 untreated previously and 5 recurrent.

[Application of rhomboid flap for the repairment of postoperative defects in head and neck cutaneous tumor].

Objective: To summarize the clinical repairment experience of postoperative skin defects in head and neck cutaneous tumor.

Method: From July 2002 to September 2006, 24 patients with head and neck cutaneous tumor were treated in our department. Every specimen and resection margin of all cases were monitored by intraoperative frozen section.

[Treatment of hypopharyngeal stricture after total laryngectomy by interventional therapy with inner-cavity cradle].

Objective: To investigate the main factors in the treatment of hypopharyngeal stricture after total laryngectomy by interventional therapy with inner-cavity cradle.

Method: Nine patients of hypopharyngeal stricture after total laryngectomy accepted the interventional therapy with inner-cavity cradle.

Result: The interventional therapy with inner-cavity cradle succeeded in 8 patients, the difficulty of swallowing was obviously improved immediately after the therapy.
