Unusual coexistence: branchial cleft cyst harboring papillary thyroid carcinoma with lymph node metastasis - a rare case report and clinical insights.

Background: The simultaneous occurrence of Branchial Cleft Cyst (BCC) and Papillary Thyroid Carcinoma (PTC) represents an unusual malignant tumor, with cases featuring associated lymph node metastasis being particularly rare. This combination underscores an increased potential for metastasis, and the assessment of neck masses, particularly on the lateral aspect, may inadvertently overlook the scrutiny of the thyroid. Therefore, healthcare providers should exercise vigilance, especially in patients over the age of 40, regarding the potential for neck masses to signify metastasis from thyroid malignancies. Currently, surgical intervention stands as the primary effective curative method, while the postoperative administration of radioactive iodine therapy remains a topic of ongoing debate. Case report: In the presented case, a 48-year-old male patient with a right neck mass underwent surgical intervention. The procedure included the excision of the right neck mass, unilateral thyroidectomy with isthmus resection, and functional neck lymph node dissection under tracheal intubation and general anesthesia. Postoperative pathology findings revealed the coexistence of a BCC with metastatic PTC in the right neck mass, as well as papillary carcinoma in the right thyroid lobe. Lymph node metastasis was observed in the central and levels III of the right neck. Conclusion: The rare amalgamation of a BCC with PTC and concurrent lymph node metastasis underscores the invasive nature of this malignancy. Healthcare professionals should be well-acquainted with its clinical presentation, pathological characteristics, and diagnostic criteria. A multidisciplinary approach is strongly recommended to enhance patient outcomes.

The feasibility and clinical significance of lateral approach thyroidectomy.

BACKGROUND: By comparing the three lateral approaches to thyroidectomy, the feasibility and clinical effects were analyzed, and the advantages of the lateral approach were summarized. METHODS: From January 2022 to January 2023, 52 patients with thyroid cancer admitted to our department were selected and subjected to Lateral approach for thyroidectomy. Among them, 31 patients underwent thyroidectomy via the supraclavicular approach, 13 patients underwent endoscopic thyroidectomy via the subclavicular approach, and 8 patients underwent endoscopic thyroidectomy via the axillary approach. The basic conditions, surgical conditions, complications, postoperative pain scores and postoperative satisfaction of patients in the three approach surgery groups were recorded and analyzed. RESULTS: There were no significant differences among the three approach groups in terms of patient characteristics, number of central lymph node dissections, intraoperative blood loss, postoperative drainage volume, duration of drainage tube placement, length of hospital stay, postoperative pain, satisfaction, and complications. However, the operation time was longest in the subclavicular approach group, followed by the axillary approach group, and shortest in the supraclavicular approach group. The total hospitalization cost was highest in the axillary approach group, followed by the subclavicular approach group, and lowest in the supraclavicular approach group. CONCLUSION: The lateral approach for thyroidectomy is deemed a safe and effective method. The three different approach paths gradually increase in length, allowing for the accumulation of anatomical experience. This approach has a shorter learning curve for clinical doctors and is a favorable choice for patients seeking aesthetic benefits.

LncRNA AC093850.2 predicts poor outcomes in patients with triple-negative breast cancer and motivates tumor progression by sponging miR-4299.

BACKGROUND: Accumulating evidence displays that non-coding RNAs (ncRNAs) are involved in the progression of triple-negative breast cancer (TNBC). This study aimed to investigate the role of lncRNA AC093850.2 in TNBC. METHODS: The AC093850.2 levels were compared using RT-qPCR in TNBC tissues and corresponding normal tissues. The Kaplan-Meier curve method was conducted to assess the clinical significance of AC093850.2 in TNBC. Bioinformatic analysis was used to predict potential miRNA. Cell proliferation and invasion assays were carried out to explore the function of AC093850.2/miR-4299 in TNBC. RESULTS: lncRNA AC093850.2 expression is raised in TNBC tissues and cell lines, which is related to the shorter overall survival of patients. AC093850.2 is directly bound to miR-4299 in TNBC cells. Downregulation of AC093850.2 reduces tumor cell proliferation, migration, and invasion abilities, while miR-4299 silence attenuated AC093850.2 silencing induced inhibition of cellular activities in TNBC cells. CONCLUSION: In general, the findings suggest that lncRNA AC093850.2 was closely related to the prognosis and progression of TNBC by sponging miR-4299, which might be a prognosis predictor and potential target for treating TNBC patients.

Haplotype analysis on correlation between transcription factor 7-like 2 gene polymorphism and breast cancer risk.

BACKGROUND: Up to now, limited researches focused on the association between transcription factor 7-like 2 gene (TF7L2) gene single nucleotide polymorphisms (SNPs) and breast cancer (BC) risk. The aim of this study was to evaluate the associations between TF7L2 and BC risk in Chinese Han population. METHODS: Logistic regression model was used to test the correlation between polymorphisms and BC risk. Strength of association was evaluated by odds ratio (OR) and 95% confidence interval (CI). Generalized multifactor dimensionality reduction (GMDR) was applied to analyze the SNP-SNP and gene-environment interaction. RESULTS: Logistic regression analysis indicated that the BC risk was obviously higher in carriers of rs1225404 polymorphism C allele than that in TT genotype carriers (TC or CC versus TT), adjusted OR (95%CI) =1.40 (1.09-1.72). Additionally, we also discovered that people with rs7903146- T allele had an obviously higher risk of BC than people with CC allele (CT or TT versus CC), adjusted OR (95%CI) =1.44 (1.09-1.82). GMDR model was used to research the effect of interaction among 4 SNPs and environmental factors on BC risk. We discovered an important two-locus model (p = 0.0100) including rs1225404 and abdominal obesity, suggesting a potential gene-environment correlation between rs1225404 and abdominal obesity. In general, the cross-validation consistency of two-locus model was 10 of 10, and the testing accuracy was 0.632. Compared with subjects with normal waist circumference (WC) value and rs1225404 TT genotype, abdominal obese subjects with rs1225404 TC or CC genotype had the highest BC risk. After covariate adjustment, OR (95%CI) was 2.23 (1.62-2.89). Haplotype analysis indicated that haplotype containing rs1225404-T and rs7903146-C alleles were associated with higher BC risk. CONCLUSIONS: C allele of rs1225404 and T allele of rs7903146, interaction between rs1225404 and abdominal obesity, rs1225404-T and rs7903146-C haplotype were all related to increased BC risk.

TAP Test Image Dynamic Tracking Study after Thyroid Cancer Surgery and after Radiotherapy and Chemotherapy.

Thyroid cancer is a relatively common endocrine gland malignant tumor; if improper treatment, there will be a high risk of recurrence or metastasis, and abnormal sugar chain glycoprotein (TAP) has a close relationship with the development of the disease; therefore, the purpose of this article is to discuss abnormal sugar chain glycoprotein (TAP) as thyroid cancer curative effect evaluation and radiation and chemotherapy after surgery clinical significance. In this paper, 95 patients with thyroid cancer diagnosed in a hospital were selected as the study objects and treated as the observation group. The clinical and follow-up data of the observation group were retrospectively analyzed. Meanwhile, 55 healthy patients were randomly selected as the control group. TAP, squamous cell carcinoma antigen (SCC) level, and carcinoembryonic antigen (CEA) level were detected in peripheral blood of 95 patients with thyroid cancer before and after treatment. The short-term efficacy was evaluated by chest CT examination, and the changes of the three markers before and after treatment and the correlation with the short-term efficacy of the patients were compared. According to the results of testing, the TAP positive expression in patients before radiotherapy can better predict the recent curative effect has certain clinical value; before radiotherapy TAP positive expression rate was significantly higher than that of healthy people, TAP positive expression quantity decreased obviously after radiation treatment, and patients with a recent radiotherapy curative effect is good or bad and negatively correlated with the degree of TAP protein positive expression; TAP high protein in patients with recent poor radiation effects, prompt the factor can be predicted in the near future curative effect of the molecular markers, and can TAP level for clinicians provide certain reference for targeted therapy.
