Objective:Paragangliomas （PGLs） are chromaffin cell tumors originating from paraganglia and are classified as neuroendocrine neoplasms.They predominantly occur along the distribution area of the paraganglia, commonly occurring between the ages of 20 and 40, with a slight male predominance.They are most frequently found in the axial regions from the skull base to the pelvic cavity. Paragangliomas in the head and neck region typically lack endocrine functionality and primarily manifest through local mass effects. However, clinical signs and symptoms alone cannot reliably distinguish between metastatic and non-metastatic cases. Clinically apparent metastatic paragangliomas are relatively rare. Herein, we present a case of a paraganglioma located in the region of the jugular foramen with liver, bone, and lymph node metastases, and discuss the treatment and prognosis of head and neck paragangliomas.

BACKGROUND/AIMS: The efficacy of surveillance for esophageal squamous cell neoplasia (ESCN) in patients with head and neck squamous cell carcinoma (HNSCC) remains controversial. Our study aimed to provide clinical data concerning the necessity of surveillance for detecting early ESCN in patients with HNSCC. METHODS: We retrospectively reviewed the data from 714 patients who were pathologically confirmed as having HNSCC (n=236 oral cavity cancers, 137 oropharyngeal cancers, 87 hypopharyngeal cancers, and 254 laryngeal cancers). RESULTS: Of 714 patients, during a median follow-up of 31 months, 48 ESCNs (37 synchronous and 11 metachronous) were detected in 36 patients (5%). Fifteen synchronous lesions (40.3%) were early ESCN, whereas nine metachronous lesions (81.8%) were early ESCN. The 3-year survival rates of HNSCC only and HNSCC combined with ESCN were 71.2% and 48.2%, respectively (p<0.001). Among 36 patients with ESCN, the 3-year survival rates for early and advanced ESCN were 77.7% and 21.7%, respectively (p=0.01). In the multivariate analysis, alcohol consumption and hypopharyngeal cancer were significant factors associated with the development of ESCN. CONCLUSIONS: HNSCC patients with early ESCN were similar in prognosis with patients without ESCN, in contrast to patients with advanced ESCN. Therefore, surveillance for the early detection of ESCN in patients with HNSCC, especially in alcohol drinkers and those with hypopharyngeal cancer, is warranted.

INTRODUCTIONHead and neck squamous cell carcinoma (HNSCC) is a common cancer worldwide and has a poor prognosis. A biomarker predicting the clinical outcome of HNSCC patients could be useful in guiding treatment planning. Overexpression of the T lymphoma invasion and metastasis 1 (Tiam1) protein has been implicated in the migration and invasion of neoplasms. However, its role in HNSCC progression needs to be further validated. We detected the expression of Tiam1 in normal and tumor tissues and determined its association with clinical outcomes in patients with HNSCC.

METHODSWe measured the expression of Tiam1 in normal and cancerous tissue samples from the patients with HNSCC treated at Sun Yat-sen University Cancer Center between 2001 and 2008. The Tiam1 expression was scored from 0 to 12 based on the percentage of positively stained cells and the staining intensity. We then determined the diagnostic performance of this score in predicting overall survival (OS) and disease-free survival (DFS).

RESULTSOf the 194 evaluable patients, those with advanced disease, lymph node metastasis at diagnosis, and recurrence or metastasis during follow-up had a higher tendency of having high Tiam1 expression as compared with their counterparts (P < 0.05). The proportion of samples with high Tiam1 expression was also higher in cancerous tissues than in non-cancerous tissues (57.7% vs. 13.9%, P < 0.001). Cox proportional hazards regression analysis revealed that Tiam1 expression scores of 5 and greater independently predicted short OS and DFS.

CONCLUSIONThe Tiam1 expression is shown as a promising biomarker of clinical outcomes in patients with HNSCC and should be evaluated in prospective trials.

OBJECTIVE: To analyze the clinical feature of cervical metastatic carcinoma of unknown primary site (CCUP) for guiding clinical diagnosis and treatment. METHOD: Twenty-seven cases of CCUP during May 2007 to September 2013 in department were analyzed retrospectively. Kaplan-Meier method and Log-rank test were used for survival analysis, multivariate analysis using the Cox regression model. RESULT: There is no significant influence among gender, age and the mass position on the median survival time. Median survival time of patients with different pathological types was statistically significant (P < 0.05). Treatment affected the median surial significantly (P < 0.05) and also was the independent prognostic factors (P < 0.05). CONCLUSION The early establishment of pathological type and primary focal position can improve the prognosis. Taking treatment according to pathological types can increase the patient's survival rate. Combined treatment can prolong the patient's survival time.

The past decade has seen changes in the global trends for head and neck cancers in terms of incidence, etiologic and demographic patterns. Several case-control studies have consistently shown human papillomavirus (HPV) exposure dramatically increases the occurrence of oropharyngeal cancer. HPV related (+) oropharyngeal cancer has been found to be epidemiologically and clinically distinctive disease, characterized by younger age at onset, and strong association with reproductive behavior. The incidence of this disease is increasing sharply worldwide, whilst HPV negative (-) cancers are declining. HPV(+) cancers have significantly better survival and responses to chemoradiation, than HPV(-) counterparts. Given this superior survival, de-escalated therapies and organ preservation surgeries are being considered and on the clinical trial. Currently available prophylactic virus-like particle vaccines might be efficacious for primary prevention of HPV(+) cancers, although not validated yet. More researches are needed for the effective secondary prevention, through the deeper understanding of precancerous, molecular and pathologic changes.
