OBJECTIVETo study the expressions of key assemblies of cytoskeleton, Fascin-1, Ezrin and Paxillin, in laryngeal squamous cell carcinoma (LSCC) and their correlation with clinicopathologic characteristics, cancer recurrence and survival of patients with LSCC.

METHODSThe expressions of Fascin-1, Ezrin and Paxillin proteins were detected by immunohistochemistry in 199 cases of LSCC. Unconditional Logistic regression model or Cox proportional hazards model was used for the analyses of recurrent risks and prognostic factors.

RESULTSSignificantly increased expression of Fascin-1, Ezrin or Paxillin expression was showed in the LSCC with poorly differentiated, positively cervical lymph nodal metastasis, and clinical stage III + IV respectively (P < 0.05). The expressions of three kinds of proteins in the recurrent cases were higher than those in non-recurrent cases respectively (χ(2) were 42.479, 43.673 and 22.261, P < 0.05). The highest recurrence rate (69.1%) was observed in group of cases with the highly co-expression of the three kinds of proteins (P < 0.05). The expression of Fascin-1 (OR = 7.89, 95%CI 2.26 - 27.53, P = 0.001), or Ezrin (OR = 2.51, 95%CI 1.18 - 5.32, P < 0.001) was independent risk for recurrence. Five-year disease-free survival rates of patients with high expression of Fascin-1, Ezrin or Paxillin were lower than those of patients with negative or low expressions for the proteins (P < 0.05). Patients with highly co-expression of three kinds of proteins showed the poorest survival prognosis, with a 5-year disease free survival (DFS) of only 26.4% (P < 0.05), and expressions of three proteins were independent prognostic factors for 5-year DFS (P < 0.05).

CONCLUSIONFascin-1, Ezrin, and Paxillin were correlative with LSCC progression and might be potential predictors for cancer recurrence and survival of patients with LSCC, as well as therapeutic targets for LSCC.

OBJECTIVETo determine the optimal surgical modality for T3 glottic carcinoma.

METHODSClinical data of 57 cases of T3 glottic carcinoma were retrospectively reviewed. Their clinical characteristics, surgical procedures and prognosis were analyzed. At different ages and by surgical procedures performed, the 3-year disease-free survival rate of the patients were analyzed.

RESULTSAll cases underwent surgical procedures including total laryngectomy, near total laryngectomy and partial laryngectomy, and the 3-year disease-free survival rate was 63.2% (36/57). The 3-year disease-free survival rate of patients who received total laryngectomy was 66.7% (16/24), near total laryngectomy 50.0% (4/8), and partial laryngectomy 64.0% (16/25, P = 0.694). The 3-year survival rate of the cases ≥ 70.0 years old was 70.0% (7/10), and that of < 70 years old was 61.7% (29/47, P = 0.621). Thirty-six cases had neck dissection, including 2 cases with radical neck dissection, 6 cases with modified neck dissection, and 28 cases with selective neck dissection. The lymph node metastasis rate of all cases was 17.5%. Ten cases were diagnosed as postoperative local recurrence, including 1 cases treated with total laryngectomy, 2 cases treated with near total laryngectomy and 7 cases treated with partial laryngectomy.

CONCLUSIONSBoth total laryngectomy and partial laryngectomy are important surgical procedures for treating patients with T3 glottic carcinoma. The optimal individual surgical procedure for the patient with T3 glottic carcinoma should be determined on the basis of the local lesions and physical status. Total laryngectomy is prior to partial laryngectomy for the patients with T3 glottic carcinoma ≥ 70 years old.

OBJECTIVEWe aimed to evaluate the combined effect of a family history of cardiovascular disease (CVD) and high serum C-reactive protein (CRP) on the stroke incidence in an Inner Mongolian population in China.

METHODSA prospective cohort study was conducted from June 2002 to July 2012, with 2,544 participants aged 20 years and over from Inner Mongolia, China. We categorized participants into four groups based on the family history of CVD and CRP levels.

RESULTSWe adjusted for age; sex; smoking; drinking; hypertension; body mass index; waist circumference; and blood glucose, triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol levels. Compared with the group with no family history of CVD/low CRP levels, the group with family history of CVD/high CRP levels had a hazard ratio (HR) of 1.78 [95% confidence interval (CI), 1.03-3.07; P = 0.039] of stroke, and an HR of 2.14 (95% CI, 1.09-4.20; P = 0.027) of ischemic stroke. The HRs of hemorrhagic stroke for the other three groups were not statistically significant (all P > 0.05).

CONCLUSIONParticipants with both a family history of CVD and high CRP levels had the highest stroke incidence, suggesting that high CRP levels may increase stroke risk, especially of ischemic stroke, among individuals with a family history of CVD.
