064, P<0.05) reduced the risk of PTC. Simultaneously, positive TgAb was also a risk factor for PTC in females (OR =3.532, P<0.05), but not in males (P>0.05). The risk of PTC in females was not associated with further increase in the titer of TgAb.

TgAb may be associated with an increased risk of PTC in females, but there is no clear correlation between the risk of PTC and higher antibody titer in these patients.

The exact etiology and pathogenesis of granulomatous lobular mastitis (GLM) are yet to be illuminated. This study aimed to investigate CD68, CD163-positive M2 macrophages, CD57-positive natural killer (NK) cells, and IgG4 in GLM lesion tissue to explore their correlation with the occurrence and clinical features of GLM.

Surgical pathologic specimens of GLM were collected from patients admitted to Hunan Provincial People's Hospital between October, 2014 and October 2015. Based on the postoperative pathological diagnosis, the tissues were divided into 3 groups the experimental group (GLM, n=36), control group 1 (plasma cell mastitis, PCM, n=17), and control group 2 (breast cystic hyperplasia, n=10). Immunohistochemical staining was carried out using Elivision super testing to detect CD68, CD163, CD57, and IgG4 expression in the pathological tissue samples. The relationship between clinical parameters, including age, reproductive condition, nipple retraction, and tumor size, and the expressions of CD68, CD16erent clinical subtypes of GLM. Furthermore, our research also found that NK cells can provide a basis for GLM clinical staging.
Inflammatory cells are closely linked to the occurrence of GLM and PCM. Celastrol In our study, both the GLM and PCM groups had low expression of IgG4, but the expression level of IgG4 in GLM patients with inverted nipples was significantly higher than that in patients without inverted nipples. This suggests that there may be two different clinical subtypes of GLM. Furthermore, our research also found that NK cells can provide a basis for GLM clinical staging.
Neoadjuvant chemotherapy is usually used for treating locally advanced breast cancer. However, not all patients achieve pathologic complete response (pCR). In this study, we selected two epidermal growth factor receptor (EGFR) single nucleotide polymorphism (SNP) sites, rs1468727 and rs845552, to investigate the association between the genotypes and the response and toxicity derived from neoadjuvant chemotherapy for breast cancer.

All participants took part in clinical trial SHPD001 and SHPD002. For univariate analyses, the association between SNP and pCR or toxicity was analyzed by Chi-square or Fisher's exact test. For multivariate analyses, logistic regression was used instead.

In all, one hundred and eighteen patients were enrolled. We found that the frequency of AA genotype in rs845552 was higher than that of other genotypes in HER2-positive breast cancer (AA
AG, P=0.039; AA
GG, P=0.005; AA
AG+GG, P=0.009). link2 Multivariate logistic regression analyses showed that pCR was more difficult to be may be related to the status of HER2 in breast cancer.
Traditionally, surgical excision is recommended for benign papillary lesions in core-needle biopsy (CNB) because of their malignant potency. The aim of this study was to identify factors associated with disease upgrading to malignancy in patients with benign papillary lesions in CNB.

A total of 179 female patients were evaluated retrospectively who were diagnosed as having a benign papillary lesion in CNB and underwent a subsequent surgical excision between January 2007 and December 2016. Ultrasonography-guided CNB was performed using a 14-gauge needle gun method.

The rate of upgrade to malignancy was 10.6% (7.6% in papillary lesions without atypia
33.3% in papillary lesions with atypia; P=0.001). The univariable analysis revealed that older age at diagnosis (≥50 years old), menopause, lesion size on ultrasonography, palpability, multifocality, and atypia in CNB were associated with upgrading. The multivariable analysis revealed that age ≥50 years (OR, 4.6; 95% CI, 1.5-14.1; P=0.008), lesion size of ≥2 cm (OR, 6.4; 95% CI, 1.9-21.1; P=0.002), and atypia in CNB (OR, 5.1; 95% CI, 1.5-18.2; P=0.011) were significantly associated with upgrading to malignancy.

Upgrading to malignancy in patients with benign papillary lesions in CNB was associated with age ≥50 years, lesion size ≥2 cm, and atypia in CNB.

Differentiated thyroid carcinoma (DTC) is the most common clinical type of thyroid carcinoma. There are rare reports on the synergic effects of the different clinicopathological risk factors on the prognosis of it.

We retrospectively reviewed data on 86,032 DTC patients from the Surveillance, Epidemiology, and End Results (SEER) database. link3 Univariate and multivariate Cox regression analyses were conducted to evaluate the correlation between clinicopathological factors and the prognosis of DTC. Relative excess risk (RERI) of synergic effect, attributable proportion (AP) of synergic effect, and synergy index (SI) were calculated to assess synergic effects. Kaplan-Meier analyses with log-rank tests was used to plot the survival curve affected by different risk factors.

Histology subtype, lymph node metastasis (LNM) status, and distant metastasis (DM) were independent risk factors for cancer-specific survival (CSS) and all-cause survival (ACS) in the multivariate analysis (all, P<0.001). Patients' age at diagnosis, sex, extrathyroidal extension, and radiation also influenced prognosis (all, P<0.001). The cancer-specific mortality (CSM) and all-cause mortality (ACM) rates per 1,000 person-years were higher in patients with follicular thyroid carcinoma (FTC) and in those with N1 stage and M1 stage disease. Furthermore, we observed a significant synergic effect between histology subtype and N stage, as well as histology subtype and M stage for the CSM of DTC (RERI =48.806, AP =0.853, SI =7.565; RERI =37.889, AP =0.430, SI =1.771, respectively). However, no synergic effect was observed in the case of the N stage and M stage for the CSM of DTC (RERI =7.928, AP =0.084, SI =1.093).

Patients with histology subtype of FTC and N1 stage, histology subtype of FTC and M1 stage had significant additive synergic effects on DTC prognosis for CSM.

The rate of level V metastases is significantly low and the necessity of routine level V dissection for papillary thyroid microcarcinoma (PTMC) with clinically lateral lymph node metastasis (LNM) is still controversial.

This study enrolled 114 consecutive PTMC patients with clinically suspected lateral LNM (N1b) who underwent modified radical neck dissection (levels II to V) at Xiangya Hospital of Central South University from September 2016 to July 2019. Univariate and multivariate analyses were performed to investigate the predictive factors of level V metastasis. The area under the receiver operating characteristic (ROC) curve (AUC), accuracy, specificity and sensitivity were used to determine the predictive value.

The overall and occult rate of level V metastasis were 29.82% (34/114) and 7.02% (8/114), respectively. Univariate analysis showed that level V metastasis was significantly associated with gross extrathyroidal extension (ETE), level IV metastasis and 2-level simultaneous metastasis (all P<0.05). Gross ETE (OR =11.916, 95% CI, 1.404-102.19; P=0.023) and level IV metastasis (OR =8.497, 95% CI, 2.119-34.065; P =0.03) served as independent predictors of level V metastasis in N1b PTMC patients. The sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of gross ETE and level IV metastasis in predicting the level V metastasis were 25.3%
82.4%, 97.5%
73.8%, 82.69%
76.32%, 80%
57.04% and 75%
90.77%, respectively. The AUC of gross ETE was lower than level IV metastasis (0.605
0.781, P=0.041).

Routine level V dissection is necessary in N1b PTMC patients with level IV metastasis or gross ETE. Compared with gross ETE, level IV metastasis is superior in predicting level V metastasis.

Incidental excision of parathyroid glands is a common event during thyroid surgery and in spite the divergent results that can be obtained from the literature about its clinical significance, all efforts must be used to their preservation. Due to the autofluorescence emitted by parathyroid glands, authors began to use a custom device to inspect thyroidectomy specimens for incidentally removed parathyroid tissue; the results of using this device are presented in this manuscript.

Specimens of 40 consecutive thyroid surgeries were inspected. Localization of suspect high-fluorescence spots were recorded for confirmation with a pathological exam. Determinations of calcium and parathyroid hormone (PTH) were completed prior to surgery and at 24 hours and 15 days after the operation.

Patient age ranged from 36 to 83 years and were predominantly female (82.5%). Calcium values at 24 hours post-operation varied between 7.1 and 9.5. The PTH values ranged between 3 and 77. Thirteen patients (32.5%) presented with bily-removed glands.
Although internal mammary vessels are considered the best recipients for free flap breast reconstruction, they present the notable drawback of limited accessibility. The aim of this study was to develop a minimally invasive surgical technique for the dissection of internal mammary vessels as recipients for breast reconstruction.

From 2008 to 2018, we performed 32 unilateral microsurgical breast reconstructions (mean patient age 40.1±8.7 years; range, 23-58 years). As internal mammary vessels were exclusively used as recipients, they were dissected using a technique of minimally invasive video-assisted thoracoscopic surgery (VATS) developed in our hospital.

The mean surgery time was 5.4±0.55 hours (range, 4.5-6.5 hours), and the mean duration of VATS dissection of internal mammary vessels was 20.6±2.9 minutes (range, 16-27 minutes). Of the specific complications associated with VATS, we only observed reductions in forced expiratory volume in the first second of >15% in 3 patients (9.4%), 10-15% in 8 patients (25%), and <10% in 21 patients (65.63%). We did not have any cases of significant bleeding or postoperative infection in this series of patients. With regard to aesthetic complications, we observed 1 and 2 cases of total necrosis and partial necrosis of the deep inferior epigastric perforator (DIEP) flap, respectively and 2 cases of partial necrosis of supercharged transverse rectus abdominis muscle flap.

Endoscopic dissection of internal mammary vessels is a simple and feasible technique. When performed by experienced surgeons, it is a fast procedure that is associated with low rate of complications.
