RÉSUMÉ

Objective To investigate the prognosis relevant factors of laryngeal squamous cell carcinoma (LSCC).Methods From January 2013 to December 2013,the clinical data of 71 patients with LSCC who were initially treated in Zhejiang Cancer Hospital were retrospectively analyzed.Results Univariate analysis showed that there were statistically significant differences in survival rate between the group of supraglottic type and glottic type (60.0% vs.86.3% ,χ2 =6.284,P<0.05),the group of N0 and N+(41.7% vs.86.4% ,χ2 =16.803,P<0.01), the group of early and late stage(93.6% vs.50.0% ,χ2 =19.854,P<0.01).There were no statistically significant differences in survival rate between the group of age ≤50,>50-60,>60-70 and >70(88.9% vs.88.2% vs. 79.3% vs.62.5% ,χ2 =3.909,P>0.05),the group of T1+T2 and T3+T4(83.6% vs.62.5% ,χ2 =3.623,P>0.05),the group of high,medium,low differentiated and unsigned(75.0% vs.69.7% vs.83.3% vs.91.7% ,χ2 =3.780,P>0.05),the group of surgery,radiotherapy and surgery+radiotherapy (74.3% vs.90.9% vs.71.4% , χ2 =2.437,P>0.05).Multivariate analysis showed that age( P =0.003),treatment( P =0.048) had significant effect on the prognosis of patients,but tumor location(P=0.766),T stage(P=0.677),N stage(P=0.482),clinical stage(P=0.825),the degree of pathological differentiation(P=0.206) had no significant effect on the prognosis of patients.Conclusion More aggressive treatment should be supplied for patients with N+,advanced clinical stage and age whom the prognosis are usually poor. In addition, the proportion of tracheal tube extraction should be appreciated.

RÉSUMÉ

Peripheral blood circulating tumor DNA(ctDNA) is a kind of DNA that is released into the blood circulation system after the tumor cell somatic cell DNA is exfoliated or when the cell apoptosis is released.ctDNA is a characteristic tumor biomarker, known as " liquid biopsy" . It can reflect the invasion and metastasis of the tumor, and can monitor the effect and prognosis of the tumor.The current research is mainly focused on relatively mature breast cancer, lung cancer and other diseases.In this study, the development of ctDNA inspection technology and its current research status at home and abroad are reviewed.

RÉSUMÉ

Objective To investigate the predictive factors for central lymph node metastasis (CLNM) in papillary thyroid microcarcinoma(PTMC).Methods A retrospective study including 2511 cases of PTMC admitted from Jan.2013 to Jan.2016 were enrolled in our study.Chi-square test was used in univariate analysis.Logistic regression analysis was applied for multivariate analysis.The relation between age,sex,tumor size,multifocality,thyroidal extension,nodular goiter and central lymph node metastasis is analyzed.Results Univariate analysis showed that age,sex,tumor size,multifocality,thyroidal extension and nodular goiter had statistical significance.Age less than 45(P<0.001,x2=17.442);Male gender(P<0.001,x2=17.029);Tumor size less than 5 mm (P<0.001,x2=70.164.);Extrathyroid extension factor (P<0.001,x2=63.197);Nodular hyperplasia factor (P=0.017,x2=5.611).Multivariate analysis showed there was a significant relationship between multifocality and the central lymph node positivity.The odds ratio (OR) was 1.587 in patients with tumor foci ≥2(P<0.001).While OR increased sharply near to 3 in patients withtumor foci ≥3(OR=2.730).Tumor size(OR=1.926);Extrathyroid extension(OR=1.606).Conclusions Multifocalty,tumor size and thyroidal extension are the main predicative factors for central lymph node metastasis in PTMC.Among them,tumor foci ≥ 3 is an important predictor.Besides the conventional factors such as tumor size,thyroidal extension etc,multifocalty should also be taken into consideration.

RÉSUMÉ

Objective To investigate the clinical features of papillary thyroid microcarcinoma(PTMC) and the risk factors of central lymph node metastasis (CLNM) in PTMC patients.Methods The clinical data of 855 patients with PTMC who underwent prophylactic central lymph node dissection were retrospectively reviewed.Results In the present study,the rate of CLNM was 21.9% (187/855) in PTMC patients.In the univariate analysis,the incidence of CLNM was significantly higher in male patients,age < 45 years,tumor size > 5 mm,capsular invasion,multiple tumor and intracapsular spread (31.4 % vs.19.5 %,x2 =11.429,P =0.001;29.3 % vs.15.9 %,x2 =22.416,P =0.000;30.0% vs.14.3%,x2 =30.669,P=0.000;29.4% vs.16.8%,x2 =19.233,P =0.000;30.0% vs.19.9%,x2 =8.205,P =0.004;42.9% vs.21.3 %,x2 =5.549,P =0.018,respectively).Multivariate analysis showed that male gender,age < 45 years,tumor size > 5mm,multiplicity and capsular invasion were independent risk factors for CLNM in PTMC patients (95% CI:0.380-0.834,0.349-0.693,1.450-3.060,1.078-2.229,1.024-2.373,respectively).Conclusion A routine prophylactic central lymph node dissection should be considered particularly in male PTMC patients with age <45 years,tumor size >5 mm,capsular invasion and tumor multiplicity.

RÉSUMÉ

MicroRNA (miRNA) negatively regulates gene expression at the post-transcriptional level.Studies find that the abnormal expression of miR-151-5p in various human tumors may play an important role in the development of human tumors,especially in the invasion and metastasis.Further studies of miR-151-5p contribute to a more in-depth understanding of tumor invasion and metastasis,which have potential value in tumor diagnosis,treatment and prognosis.

RÉSUMÉ

ObjectiveTo evaluate central compartment lymph node metastasis in cN0 papillary thyroid carcinoma(PTC) patients. MethodsThe clinical data of 166 cN0 PTC patients was retrospectively analyzed. ResultsThe central compartment lymph node metastasis rate of age < 45 years group was higher than the group of age≥45 years(39% vs.22%,P <0.05).Tumor size >0.5 cm tends to metastasize more often than tumor size ≤0.5 cm(P <0.05) ; there was significantly difference in central compartment lymph node metastasis rate between upper pole tumor ( 25%,12/48 ) and middle ( 45%,13/29 ) or lower pole (43%,31/72),P < 0.01. ConclusionscN0 PTC patients with tumor located in middle pole or lower pole,tumor size > 0.5 cm or age < 45 years are at higher risks for central compartment lymph node metastasis.

RÉSUMÉ

Mucosal malignant melanoma of the head and neck is one of the rarely malignant diseases. The standard therapy for mucosal melanoma of the head and neck is radical surgery associated with adjuvant radiation. The immunotherapy and chemotherapy are confirmed effective in some degree. Molecular staging and targeted therapy will be the new tendency in the future.
