OBJECTIVETo evaluate the efficacy of pedicled supraclavicular artery island flaps for head and neck reconstruction.
METHODSReconstructive surgeries for head and neck oncologic defects were performed with the pedicled supraclavicular artery island flaps in 10 patients from May 2013 to December 2014 and the cases were review. Among them, 6 were performed for hypopharyngeal cancer, 2 for oral tongue cancer, 1 for oral base cancer and 1 for cervical esophageal cancer. The size of the flaps was measured in (5-8) cm × (6-12) cm.
RESULTSSeven flaps survived, one flap failured and two flaps had partial necrosis. Donor sites were closed primarily without morbidity.
CONCLUSIONThe pedicled supraclavicular artery island flap is an easy harvesting and reliable for head and neck reconstruction, especially suitable for otolaryngo-head and neck surgeon and maxillofacial surgeon in the local hospital.

OBJECTIVETry to use free jejunum flaps reconstruction and laryngeal preservation for squamous cell carcinoma (SCC) in the pharyngoesophageal junction.
METHODSThirteen patients who underwent resections of SCC in the pharyngoesophageal junction with free jejunal interposition from August 2007 to December 2012 were reviewed. Of them, 8 had T3 lesions, 4 had T4 lesions, and one had radiation failure with rT2 lesion. Ten patients were treated with postoperative radiotherapy with a average dosage of 56 Gy.
RESULTSThe 3 year over all survival rate was 47.9% and disease-specific survival rate was 34.2%. The surgical complications occurred in 9 patients (9/13), including one death and one flap failure. Five patients (5/13) had permanent tracheal canulation, 10 patients (10/13) resumed oral feeding and all patients achieved reasonable speech.
CONCLUSIONFree jejunum interposition can be used to reconstruct surgical defect of SCC in the pharyngoesophageal junction, thus preserving the larynx and ensuring a better quality of life for the patients.

OBJECTIVETo investigate the relationship between HPV-DNA status and p16 protein expression in oropharyngeal squamous cell carcinoma (OSCC) and their clinical significance.
METHODSSixty-six patients with oropharyngeal squamous cell carcinomas treated in the Cancer Hospital of Chinese Academy of Medical Sciences from Jan. 1999 to Dec. 2009 were included in this study. Their formalin-fixed and paraffin-embedded tumor tissue blocks met the eligibility criteria and were used in this study. A "sandwich" technique was used to prepare paraffin sections for HPV-DNA analysis. HPV-DNA was detected using the SPF10 LiPA25 version 1 assay. The expression of p16 protein was detected by immunohistochemistry. The survival rates of patients with different HPV-DNA and p16 protein status were analyzed.
RESULTSHPV-DNA was detected in 11 (16.7%) of all specimens. Expression of p16 protein was detected in 9 of the 11 patients with HPV-positive tumors, and in 12 patients of 55 HPV-negative tumors. The expression of p16 protein was highly correlated with the presence of HPV-DNA (P < 0.001). The tumors were classified into three groups based on the p16 protein expression and HPV-DNA status: group A (9 patients): HPV(+) and p16 protein(+); group B (14 patients): HPV-DNA(+)/p16 protein(-) or HPV-DNA(-)/p16 protein(+); and group C (43 patients): HPV-DNA(-)/p16 protein(-). The 3-year OS rates of these 3 groups were 100%, 77.8% and 42.0% (P = 0.001), and their DSS rates were 100%, 77.8% and 46.4%, respectively(P = 0.004).
CONCLUSIONSIn oropharyngeal squamous cell carcinomas, p16 protein expression is highly correlated with the presence of HPV-DNA, and might be a surrogate marker for HPV-positive OSCC. Combination of p16 protein and HPV-DNA status detection may help to more accurately stratify oropharyngeal carcinomas and predict their prognosis.

OBJECTIVEResection of local advanced hypopharyngeal cancer often results in laryngeal preservation impossible. Free flaps were used to reconstruct and to preserve functional larynx.
METHODSRetrospective review of 11 patients who underwent resections of extended squamous cell carcinoma of hypopharynx from September 2005 to September 2011. Of 11 patients, 5 had T3 lesions and 6 had T4 lesions; 2 underwent radiotherapy before surgery and other 9 had postoperative radiotherapy (60 Gy). A total of 12 free flaps, including 10 radial forearm flaps and 2 anterolateral thigh flaps, was used in the 11 patients for laryngo pharyngeal reconstruction.
RESULTSThe 3 year over all survival rate and disease-specific survival rate were 43.6% and 48.0%, respectively. The incidence of surgical complications was 72.7%, including 1 with carotid blow-up, 2 flap failure, 3 fistula, and 1 stenosis. The rate of decannulation was 72.7%, 90.9% patients were with oral feeding and 81.8% patients achieved reasonable speech.
CONCLUSIONFree flaps can be used to reconstruct a functional larynx in local advanced hypopharyngeal carcinoma, ensuring a better quality of life for patients.

OBJECTIVETo analyze the clinical characteristics, prognosis and molecular biological changes of tonsillar squamous cell carcinoma (TSCC).
METHODSRetrospective analysis of 61 TSCC cases treated from January 1999 to December 2012. Demographic data and clinical charts, including histologic grade of tumor, treatment and outcome of the patients, were reviewed.Human papillomavirus (HPV)-DNA were detected using SPF10-DNA enzyme immunoassay and LiPA genotyping method. Expressions of p16 and p53 proteins were examinated by immunohistochemistry. Survival rate was calculated with SPSS 19.0 software using the Kaplan-Meier method.
RESULTSThere were 55 males and 6 females, with a median age of 57 years. Of the 61 TSCC, 21 were with well differentiation, 19 with moderate differentiation and 21 with poor differentiation, including 7 patients at stage II, 10 at stage III and 44 at stage IV. HPV-positive rate of TSCC was 29.5% (18/61) and high-risk HPV-16 subtype accounted for 72.2% (13/18). The percentage of famel patients in HPV-positive TSCC was higher than HPV-negative TSCC (22.2% vs 4.7%).HPV-positive TSCC was more common in non-smoking patients (50.0% vs 79.1%, χ(2) = 5, 155, P = 0.023) and non-drinking patients (27.8% vs 51.2%, χ(2) = 4.346, P = 0.037). HPV-positive TSCC mostly presented with high expression of p16 protein (88.9% vs 16.3%, χ(2) = 28.481, P = 0.000), and low expression of p53 protein (72.7% vs 46.5%, χ(2) = 5.028, P = 0.025). The prognosis of patients with HPV-associated TSCC was significantly better than non-HPV-associated TSCC, and The 3-year and 5-year overall survival rates of patients with HPV-positive TSCC were higher than those of patients with HPV-negative TSCC (87.7% vs 49.5% and 78.9% vs 33.0%, respectively).
CONCLUSIONHPV-associated TSCC had unique clinicopathological and molecular biological features, showing better prognosis compared to HPV-negative TSCC.

OBJECTIVETo investigate the risks for occult carcinoma in contralateral nodules for unilateral papillary thyroid carcinoma.
METHODSThe study included 157 consecutive cases of unilateral papillary thyroid carcinoma with benign nodules in the contralateral lobe identified by preoperative ultrasound or fine-needle aspiration from January 2011 to December 2013. The patients received total thyroidectomies and neck lymph node dissections. The frequency and predictive factors for contralateral occult carcinoma in these patients were analyzed.
RESULTSA total of 68 patients (43.3%) had occult papillary thyroid carcinoma in the contralateral lobe and the maximum diameter of contralateral occult papillary carcinoma ranged from 0.1 to 1.2 cm, including ≤ 0.5 cm in 56 patients, 0.5-1.0 cm in 9 patients and >1.0 cm in 3 patients respectively. In univariate analysis, occult carcinoma in the contralateral lobe was associated with patient age (χ(2) = 7.266, P = 0.007) and pathologically multifocality in the ipsilateral lobe (χ(2) = 5.090, P = 0.024), but not with family history, tumor size, thyroid function, Hashimoto's thyroiditis, perithyroidal invasion, multifocality in the ipsilateral lobe, clinically or pathologically node-negative neck. In multivariate Logistic an analysis, age (OR = 1.054, P = 0.001) and multifocality in the ipsilateral lobe on final pathology (OR = 2.443, P = 0.021) were independent predictive factors for contralateral occult papillary thyroid carcinoma.
CONCLUSIONSOccult carcinoma is common in the contralateral "benign" nodules in patients with unilateral papillary thyroid carcinoma especially in young patients or the cases with multifocal tumors.

OBJECTIVETo study clinicopathologic factors related to central lymph node (CLN) metastasis in different subregions for unilateral papillary thyroid carcinoma (PTC) with clinical N0.
METHODSA total of 145 PTC cases with clinical N0 treated in the same group of the department of head and neck surgery, Cancer Hospital, Chinese Academy of Medical Science between Jan. 2011 and Jan. 2014 was analysed retrospectively. Clinicopathologic factors related to CLN metastasis in different subregions were analyzed, including sex, age, tumor size, extrathyroidal extension, and multifocal tumor.
RESULTSCLN metastases existed in 57.9% (84/145) cases and the incidences of ipsilateral paratracheal, pretracheal, and prelaryngeal metastasis were 53.8%, 24.1% and 11.3% respectively. Right paratracheal lymph node metastasis occurred in anterior (17/38, 44.7%) and posterior (12/38, 31.6%) to the recurrent laryngeal nerve. Multivariate analysis indicated that extrathyroidal extension (OR = 4.49, 95%CI 1.80-11.20, P = 0.001) and tumor size (OR = 2.17, 95%CI 1.06-4.45, P = 0.034) were independent risk factors for ipsilateral paratracheal CLN metastasis; ipsilateral paratracheal CLN metastasis (OR = 2.12, 95%CI 0.08-4.60, P = 0.003) was an independent risk factor for pretracheal CLN metastasis.
CONCLUSIONSA high risk of CLN metastasis especially ipsilateral paratracheal metastasis exists in DTC with clinical N0. Ipsilateral paratracheal, pretracheal and prelaryngeal CLN dissection should be conducted when maximum tumor diameter more than 1 cm or extrathyroidal extension. CLN anterior and posterior to the recurrent larygeal nerve should be removed simultaneously when the ipsilateral paratracheal CLN metastasis at right side. Total thyroidectomy and contralateral paratracheal CLN dissection should be conciderded in multifocal tumor.
