Objective:To investigate the clinical characteristics of patients complicated with Hashimoto’s thyroiditis (HT) and papillary thyroid micro-carcinoma (PTMC) and risk factors for central lymph node metastasis (CLNM) by analyzing the clinical data.Methods:Clinical data of 770 patients with PTMC admitted to Head and Neck Surgery Center of Sichuan Cancer Hospital from May. 2015 to Nov. 2017 were retrospectively analyzed, including 250 HT-PTMC patients (observation group) and 520 non-HT-PTMC patients (control group) . There were 197 males and 573 females, with a male to female ratio of 1.00:2.91. Into observation indexes included patient’s age, gender, serum thyroid stimulating hormone (TSH) , thyroglobulin antibody (TG-Ab) , thyroid peroxidase antibody (TPO-Ab) , number of foci, diameter of foci, calcification of foci, location of foci (with or without extra-glandular invasion) , number of nodules (no matter benign or malignant) , and lymph node metastasis in central and lateral cervical regions. SPSS 22.0 software was used for statistical analysis. Normally distributed data were expressed ± s. The difference between observation group and control group was compared by chi-square test of single factor analysis. The risk factors of CLNM of the observation group were analyzed with multivariate Logistic regression, the difference was statistically significant if P<0.05. Results:There were statistically significant differences between the observation group and the control group in age ( P=0.006) , gender ( P<0.001) , TSH ( P<0.001) , TG-Ab ( P<0.001) , TPO-Ab ( P<0.001) , number of nodules ( P=0.016) , and central lymph node ( P<0.001) . Compared with non-HT-PTMC group, HT-PTMC group had a higher proportion of women under 55 years old, and both TG-Ab and TPO-Ab had higher positive rates. Patients with HT-PTMC were more likely to show polynodule changes, but their central lymph node metastasis rate was lower than that of the non-HT-PTMC group. Single-factor analysis showed that the number of cancer foci, calcification of cancer foci, and location of cancer foci were significantly correlated with the CLNM of HT-PTMC patients (all P<0.001) . Multivariate Logistic regression analysis showed that multiple cancer foci ( P<0.001) , invasion and capsule ( P<0.001) , and cancer foci with calcification ( P=0.005) were independent risk factors for CLNM. Conclusions:HT-PTMC is more common in women under 55 years of age, and most of them show multiple nodules in bilateral glandular lobes, often accompanied by elevated serum TSH, TG-Ab and TPO-Ab levels. Meanwhile, the lymph node metastasis rate of HT-PTMC is relatively low, and the prognosis may be relatively good. In HT-PTMC, the risk of multiple carcinoma foci, cancer foci with calcification, cancer foci invasion and the occurrence of CLNM is higher. Preventive central lymph node dissection helps to reduce the occurrence of postoperative cervical lymph node recurrence.

OBJECTIVE: To evaluate the diagnostic efficacy of Kaiser score for breast lesions presenting as non-mass enhancement. METHODS: We collected data from patients with breast lesions presenting as non-mass enhancement on preoperative DCE-MRI between January, 2014 and June, 2019. All the cases were confirmed by surgical pathology or puncture biopsy. With pathology results as the gold standard, we evaluated the diagnostic efficacy of Kaiser score and MRI BI-RADS classification and the consistency between the diagnostic results by the two methods and the pathological results. RESULTS: A total of 90 lesions were detected in 88 patients, including 28 benign lesions (31.1%) and 62 malignant lesions (68.9%). For diagnosis of the lesions, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of Kaiser Score were 100%, 75%, 89.9%, 100% and 92%, as compared with 93.5%, 46.4%, 79.5%, 76.5% and 78.9% of MRI BI-RADS, respectively. The diagnostic specificity of Kaiser score was significantly higher than that of BI-RADS classification (=0.021). CONCLUSIONS The Kaiser score system provides a diagnostic strategy for BI-RADS classification of breast lesions with non-mass enhancement and has a better diagnostic efficacy than BI-RADS classification alone. The use of Kaiser score can significantly improve the diagnostic specificity of such breast lesions for inexperienced radiologists.

Objective: To explore the advantages and clinical efficacy of free chimeric perforator flap based on the descending branch of circumflex femoral artery applied to tongue reconstruction after advanced tongue cancer resection. Methods: From October 2013 to December 2018, 57 cases received tongue and oral base reconstruction surgeries using the descending branch of circumflex femoral artery chimeric perforator flap, including 39 males and 18 females, ranged from 20 to 76 years old. And all cases were with stage T3 and T4 tongue cancers, including 35 cases of squamous cell carcinoma, 7 cases of low differentiation cancer, 5 cases of oncosarcoma, and 10 cases of adenoid cystic carcinoma. The tongue was reconstructed by using perforator flap and muscle flap to fill the dead space at the oral floor. The artery anastomoses with the superior thyroid artery or facial artery in the receiving area, and the vein anastomoses with the internal jugular vein in the receiving area. The shape, function and local complications of the reconstructed tongue were observed after operation. Results: Of 57 cases, only one case had partial necrosis of flap, while other 56 cases with chimeric perforator flap survived. Postoperative gastric tube and tracheal cannula were removed in all patients, no cases with oral fistula. All donor sites were sutured in one stage. Postoperative radiotherapy was performed in 41 of the patients. All patients were followed up for 3 to 60 months (average of 20.7 months), with satisfactory esthetic and functional results in reconstructed tongues. Only linear scars were left in the donor areas of the legs, and no lower limb dysfunction was observed. Conclusions The descending branch of circumflex femoral artery chimeric perforator flap can used for repairing simultaneously the defects of both tongue and oral base. It is helpful to avoid the occurrence of oral fistula and to provide the reconstructed tongue with a good function. It is a good choice to use the descending branch of circumflex femoral artery chimeric perforator flap for tongue reconstruction after resection of advanced tongue cancer resection.

Objective To analyze the correlation between the molecular subtypes of non-mass enhancement (NME)breast cancer and MRI findings.Methods A retrospective analysis of MRI images and clinicopathological data of 62 patients with NME breast cancer who received 3.0T breast MRI multimodal scan from January 201 5 to June 201 9 was conducted.Molecular subtypes were classified by immunohistochemical staining.The differences between MRI findings of NME breast cancer and molecular subtypes were compared by ch-i square test and Fisher exact probability method,and the correlation between them was analyzed by cross contingency table.Results The differences of molecular subtypes of NME breast cancer in the internal enhancement and peritumoral edema were statistically significant (P＜0.05),while the differences in the TIC,lesion distribution type and peritumoral vascular were not statistically significant (P＞0.05).Conclusion Luminal A type was less prone to peritumoral edema in NME breast cancer.Luminal B type was mainly heterogeneous enhancement. HER-2 overexpression type and triple negative type are mainly clustered ring enhancement,and prone to peritumoraledema.Different molecular subtypes of NME breast cancer have certain MRI characteristics,which is expected to provide a non-invasive evaluation for the preoperative treatment of NME breast cancer.
