ObjectiveTo investigate association between BRAFV600E gene mutation and extrathyroidal extension (ETE) among patients with papillary thyroid carcinoma (PTC).MethodsA retrospective study was conducted to collect all PTC surgical patients in the Renmin Hospital of Wuhan University from 2017 to 2019. The patients tested for BRAFV600E gene mutation were selected, and the association between BRAFV600E gene mutation and ETE were analyzed.ResultsThe BRAFV600E gene mutation test was performed only in 273 cases, 223 and 50 of whom were BRAFV600E gene with and without mutation, respectively; 194 and 79 of whom had ETE and no ETE, respectively. Univariate analysis showed that the incidence rate with BRAFV600E gene mutation was higher in the patients with ETE as compared with the patients without ETE (86.1% vs 70.9%, P=0.003) and the incidence rate of ETE was higher in the patients with BRAFV600E gene mutaton than in the patients without BRAFV600E gene mutaton (74.9% vs 54.0%, P=0.003). In addition, the incidence rates of ETE in the patients with tumor diameter >1 cm, bilaterality, and multifocality were higher than those in the patients with tumor diameter ≤1 cm (86.7% vs 61.3%, P<0.001), unilaterality (89.6% vs 63.8%, P<0.001), and single lesion (85.7% vs 60.9%, P<0.001), respectively. The incidence rate of ETE was increased with the increase of lymph node stage (P=0.003). Multivariate logistic regression analysis showed tumor size >1 cm [OR=3.606, 95%CI (1.758, 7.396), P<0.001], multifocality [OR=2.524, 95%CI (1.154, 5.519), P=0.020], with BRAFV600E gene mutaton [OR=3.022, 95%CI (1.443, 6.326), P=0.003] were the risk factors for ETE.ConclusionThe preliminary results of this study suggest that PTC patients with BRAFV600E gene mutaton are more likely to gross ETE.
ObjectiveTo explore therapeutic efficacy of parathyroidectomy (PTX) in treatment of secondary hyperparathyroidism (SHPT) in patients with end-stage renal disease.MethodsThe clinical data of 50 patients who underwent PTX for uremic SHPT from January 2016 to March 2018 were collected retrospectively. The changes of serum calcium, phosphorus, and intact parathyroid hormone (iPTH) before the surgery and 1 d, 7 d, 1 month, 3 months and 12 months after the surgery were analyzed. In addition, the improvement of clinical symptoms together with the postoperative recurrence and complications were observed.ResultsTen patients underwent the subtotal PTX (SPTX), 5 cases underwent the total PTX (TPTX), and 35 cases underwent the TPTX with autotransplantation (TPTX+AT). The PTXs were performed successfully in 47/50 (94.0%) patients. After the PTX, the bone pain and skin itching were alleviated, 3 cases had the temporary injury of recurrent laryngeal nerve and the hypoparathyroidism was found in 1 case. The levels of postoperative serum iPTH, calcemia, and phosphorus were lower than those at the preoperative level, the differences were statistically significant (P<0.050). The postoperative hypocalcemia was frequently seen in 38/50 (76.0%) patients, and it was effectively controlled by the intravenous calcium. After the follow-up for 3 months, the SHPT recurred in 5 cases (10.0%), of whom 3 cases underwent the TPTX+AT. The relapse rate in 12 months after the operation was 9.1% (2/22). There were no statistical differences among the three PTXs methods in the operation successful rate (χ2=3.351, P=0.211) and relapse rates in 3 months (χ2=1.321, P=0.753) and 12 months (χ2=1.794, P=0.411) after the operation.ConclusionsIn China, TPTX+AT is more common than SPTX and TPTX in clinical application. Operations of SPTX, TPTX, and TPTX+AT are safe and effective therapeutic methods for uremic SHPT, which can significantly improve biochemical indicators and quality of life of patients.
ObjectiveTo study on the first metastasis pattern and prognostic factors in patients with recurrent and metastatic breast cancer.MethodsThe study selected 147 patients with metastatic breast cancer who were diagnosed for the first time in the Breast Thyroid Center and Oncology Department, the People's Hospital of Wuhan University from June 2016 to June 2018. The model of first metastasis and the first diagnosis of prognosis may be affected. The age at diagnosis of breast cancer, tumor size, lymph node metastasis, hormone receptor status, HER-2 status, number of metastatic organs, tumor location, molecular typing, etc. were retrospective analyzedResultsThe most common metastatic sites for breast cancer was bone metastases in 55 patients (37.41%), followed by lung metastasis and liver metastases, 29 (19.73%) and 24 (16.33%), respectively. Univariate analysis showed that the number of lymph node metastasis, HER-2 status, organ number of first-time metastasis, and endocrine therapy were significant factors affecting metastatic survival time, and the difference was statistically significant (P<0.05). Multivariate analysis showed that the number of lymph node metastasis, the number of metastatic organs and HER-2 were independent risk factors for advanced breast cancer (P<0.05).ConclusionsThe most common metastasis of breast cancer patients after surgery is bone, followed by lung metastasis and liver metastasis. The number of lymph node metastases, the number of metastatic organs, HER-2 status, and endocrine therapy are independent factors influencing the prognosis of patients with recurrent metastasis.
ObjectiveTo summarize the current treatment status of uremic secondary hyperparathyroidism (SHPT) in order to improve the understanding of uremic SHPT and to guide clinical work.MethodThe relevant literatures at home and abroad on surgical treatment of uremic SHPT were readed and reviewed.ResultsFor intractable SHPT patients with ineffective medical treatment, surgical treatment was still irreplaceable, which could significantly improve biochemical indicators and quality of life of SHPT patients. However, there was no unified standard for surgical indications and the choice of different operation methods. In addition, there was a certain controversy about whether there was a need for preoperative parathyroidectomy in patients with SHPT who were willing to have a kidney transplant.ConclusionAlthough there are still some problems need to be solved in surgical treatment of SHPT, however, it’s widely recognized and used by clinicians, which can improve the symptoms of SHPT patients and bring bettersurvival benefits.
ObjectiveTo analyze therapeutic effect of ultrasound-guided vacuum-assisted rotary excision with tube irrigation drainage in treatment of granulomatous mastitis (GM).MethodsThe clinical data of 120 patients with GM from January 2018 to December 2018 in the Renmin Hospital of Wuhan University were analyzed. Sixty patients were treated with the ultrasound-guided vacuum-assisted rotary excision with tube irrigation drainage (control group), and the other 60 patients were treated with the metronidazole solution combined with dexamethasone on the basis of the control group (observation group). The therapeutic period, total effective rate, postoperative appearance of breast, and recurrence rate were analyzed. While the pathogenic bacteria was analyzed by the microbial culture and the pathogen gene detection.ResultsThere were no significant differences in the baseline data between the two groups (P>0.05). The ultrasound-guided vacuum-assisted rotary excisions were successfully performed in all 120 patients. The therapeutic period of the observation group was shorter than that of the control group (t=–3.633, P<0.001). The total effective rate and rate of excellent and good of postoperative breast appearance had no significant differences between the two groups (total effective rate: 96.7% versus 90.0%, χ2=1.922, P=0.166; rate of excellent and good of postoperative breast appearance: 96.7% versus 88.3%, χ2=1.205, P=0.272). The recurrence rate of the observation group was lower than that of the control group (χ2=5.175, P=0.023). The positive rates of bacteria were 25.8% and 58.8% in the 120 cases by the microbial culture and 52 cases by the pathogen gene detection, respectively, which had a statistical difference (χ2=16.974, P<0.001), the same conclusions were obtained in the observation group and the control group (χ2=6.691, P=0.010; χ2=9.379, P=0.002).ConclusionsUltrasound-guided vacuum-assisted rotary excision with tube irrigation drainage is well applied in treatment of GM. It could maintain a good shape of breast. Use of metronidazole solution combined with dexamethasone after surgery could shorten therapeutic period and reduce recurrence rate.
ObjectiveTo explore the immune biomarkers for prognosis of breast cancer and to construct a risk assessment model.MethodsThe gene expression of breast cancer samples was retrieved from The Cancer Genome Map (TCGA) database and immune related genes (IRGs) were retrieved from the ImmPort database. Cox proportional hazards regression and least absolute shrinkage and selection operator (LASSO) regression were used for prognostic analysis. Gene set enrichment analysis ( GSEA) was used to explore biological signaling pathways. ESTIMATE and CIBERSORT algorithms were used to explore the relationship between risk score and tumor immune microenvironment.ResultsNine kinds of immune-related differentially expressed genes independently related to prognosis were identified: adrenoceptor beta 1 (ADRB1), interleukin 12B (IL12B), syndecan 1 (SDC1), thymic stromal lymphopoietin (TSLP), fibroblast growth factor 19 (FGF19), fatty acid binding protein 7 (FABP7), interferon epsilon (IFNE), tumor necrosis factor receptor superfamily member 18 (TNFRSF18) and interleukin 27 (IL27). The risk assessment equation constructed by these nine kinds of genes had powerful predictive ability. The “neurotrophin signaling pathway” and “adipocyte factor signaling pathway” were activated in patients of high-risk group, and “leukocyte transendothelial migration” “WNT signaling pathway” “FcεRI signaling pathway” “valine, leucine and isoleucine biosynthesis” and “protein export pathway” were activated in patients of low-risk group. A variety of tumor-killing immune cells were significantly enriched in the tumor-infiltrating immune cells of patients in the low-risk group. The immunosuppressive immune cells were significantly enriched in tumor infiltrating immune cells of patients in high-risk group.ConclusionIRGs prognostic signatures are an effective potential predictive classifier in breast cancer treatment.
Objective To summarize the research progress of immunotherapy for metastatic breast cancer. Method Literatures about immunotherapy for metastatic breast cancer were reviewed by searching the literatures in domestic and foreign database. Results In recent years, immunotherapy had been initially attempted in patients with metastatic breast cancer and showed its unique value. It provided a new way to improve the therapeutic effect and prolong the survival time of patients with metastatic breast cancer. ConclusionsImmunotherapy is the most effective in triple-negative metastatic breast cancers. The immuno-oncology needs to be developed to improve the clinical benefits of immunotherapy for breast cancer.
Objective To summarize the development of endoscopic thyroid surgery and expound the advantages and disadvantages. Method Reviewed the domestic and foreign literatures on different ways of endoscopic thyroid surgery. Results Gagner tried accomplish subtotal parathyroidectomy with endoscope at the first time in 1996. And then, Hüscher improved the endoscope technology and applied on thyroidectomy in 1997. Henceforth, endoscopic thyroid surgery had developed rapidly, from small neck incision surgery, such as endoscopic assisted small neck incision thyroidectomy, to traceless neck surgery, such as thoraco mammary approach, areola approach, axillary approach, retroauricular approach, combined approach, etc., to traceless body surface skin surgery in recent years, such as natural cavity oral approach. Completed endoscopic surgery makes the incision scar hide or even disappear, which had attracted the attention and learning of thyroid specialist clinicians all over the world. The choice of patients was more and more broad and diverse, and all kinds of approaches had different advantages and disadvantages.Conclusions The advantages, disadvantages, indications and contraindications of various endoscopic approaches are different. According to the location differences of individual thyroid masses and the requirements for aesthetics, the most appropriate endoscopic thyroid approach is selected to achieve the optimal solution of manual approach.
ObjectiveTo investigate the research progress of etiology, pathogenesis, diagnosis, differential diagnosis, and treatment of granulomatous lobular mastitis (GLM). MethodA comprehensive analysis was conducted by reviewing the domestic and foreign literatures on GLM and combining with clinical experience. ResultsGLM was a relatively rare chronic inflammatory disease of the breast, and the number of patients had been increasing in recent years. It mainly occured in multiparous women of childbearing age. Clinically, it was characterized by a hard breast mass with or without redness and pain, and severe cases might be accompanied by nodular erythema and arthritis. Bacterial infection, especially Corynebacterium kroppenstedtii and autoimmunity were considered to be the main causes of GLM. The diagnosis of GLM needed to combine with medical history, clinical manifestations, histopathological findings, imaging findings, and laboratory tests. A multidisciplinary team for diagnosis and treatment of GLM should be established to improve the diagnostic accuracy and reduce misdiagnosis. At present, the treatment methods for GLM were mainly conservative treatment and surgical treatment, including follow-up observation, antibiotic treatment, glucocorticoid treatment, immunosuppressive therapy, surgical treatment, traditional Chinese medicine treatment, and combined treatment. ConclusionsAt present, the incidence of GLM is on the rise, but its etiology and pathogenesis are still unclear. The diagnosis needs to combine with many aspects, and it is recommended that the multidisciplinary team could improve the accuracy of diagnosis. There is still no unified standard for the selection and timing of treatment. Clinicians’ experience and patients’ wishes should be taken into account when choosing treatment options in clinical practice. Prospective and high-quality multicenter clinical trials and evidence-based medicine practice are still needed to further improve diagnosis and treatment of GLM.
ObjectiveTo summarize the current research progress in the prediction of the efficacy of neoadjuvant therapy of breast cancer based on the application of artificial intelligence (AI) and radiomics. MethodThe researches on the application of AI and radiomics in neoadjuvant therapy of breast cancer in recent 5 years at home and abroad were searched in CNKI, Google Scholar, Wanfang database and PubMed database, and the related research progress was reviewed. ResultsAI had developed rapidly in the field of medical imaging, and molybdenum target, ultrasound and magnetic resonance imaging combined with AI had been deepened and expanded in different degrees in the application research of breast cancer diagnosis and treatment. In the research of molybdenum target combined with AI, the high sensitivity of molybdenum target to microcalcification was mostly used to improve the accuracy of early detection and diagnosis of breast cancer, so as to achieve the clinical purpose of early detection and diagnosis. However, in terms of prediction of neoadjuvant efficacy research of breast cancer, ultrasound and magnetic resonance imaging combined with AI were more prevalent, and their popularity remained unabated. ConclusionIn the monitoring of neoadjuvant therapy for breast cancer, the use of properly designed AI and radiomics models can give full play to its role in the predicting the curative effect of neoadjuvant therapy, and help to guide doctors in clinical diagnosis and treatment and evaluate the prognosis of breast cancer patients.
