Improved detection of metastatic lymph nodes in esophageal squamous cell carcinoma by combined interpretation of18F-FDG PET/CT

220Objectives: To evaluate the diagnostic performance of 18F-FDG PET/CT in detecting individual lymph node metastasis using Hounsfield units of lymph nodes on non-contrast CT image component and 18F-FDG uptake in patients with esophageal squamous cell carcinoma. Methods: 203 patients with esophageal squamous cell carcinoma underwent 18F-FDG PET/CT before esophagectomy and lymph node dissection. Maximum standardized uptake value (SUVmax), mean Hounsfield unit (HU), and short axis diameters (size) were evaluated on non-contrast CT and PET images of PET/CT scan. The images were analyzed by three methods. In Method 1, nodal status was determined by FDG uptake only using cut-off values of ROC analysis. In Method 2, nodal status was determined by FDG uptake associated with mediastinal CT attenuation (70 HU). Benign lymph nodes were defined when lymph nodes with less than SUVmax of cut-off value (Method 1) or when those with a higher attenuation than 70 HU and/or containing calcifications on non-contrast CT images even if SUVmax was higher than the cut-off value. In Method 3, benign nodes were determined by the same cut-off value of SUVmax but with a higher cut-off value of HU from the ROC analysis. The sensitivity, specificity, and accuracy of each method were compared by the postoperative histologic result as a reference standard. Results: Total 1099 nodal stations were dissected, and 949 nodal stations proved to be metastases. SUVmax and size of malignant lymph nodes were higher ...

Abstract Cancer incidence rate has increased so much that it is the second leading cause of deaths worldwide after cardiovascular diseases. Sensitive and specific biomarkers are needed for an early diagnosis of cancer and in-time treatment. Recent studies have found that long non-coding RNAs (lncRNAs) participate in cancer tumorigenesis. LncRNA P73 antisense RNA 1T (TP73-AS1), also known as KIAA0495 and p53-dependent apoptosis modulator (PDAM), is located in human chromosomal band 1p36.32 and plays a crucial role in many different carcinomas. This review summarizes current findings on the role of TP73-AS1 and its ...

We presented the expressions of each member in miR-200 family in 15 types of cancer by boxplot, and analyzed the correlation among the members of miR-200 family by Spearman method. Different subgroup analyses were then performed based on the correlation among the members of miR-200 family, and the publication bias was assessed using the funnel plot of the Egger bias indicator test. RESULTS: Of 36 articles, including 15 tumor types and 4644 patients were included to perform meta-analysis. It was found that miR-200 family members can be used as independent protective factors in patients with various tumors but the miR-2...

This study is an important step forward in highlighting C1q as a new prognostic candidate biomarker for a range of carcinomas. Methods Oncomine Database Analysis The expression levels of C1QA, C1QB, and C1QC genes in various carcinomas were analyzed using Oncomine (www.oncomine.org), a cancer microarray database and web-based data mining platform from genome-wide expression analyses (22, 23). We compared the differences in mRNA level between normal tissue and carcinoma. The mRNA expression levels in neoplastic tissues compared to the healthy tissues were obtained as the parameters of p-value 2, and gene ranking in the t...

Discussion MDSCs violently emerge in pathological conditions in an attempt to limit potentially harmful immune and inflammatory responses. Mechanisms supporting their expansion and survival are deeply investigated in cancer, in the perspective to reactivate specific antitumor responses and prevent their contribution to disease evolution. These findings will likely contribute to improve the targeting of MDSCs in anticancer immunotherapies, either alone or in combination with immune checkpoint inhibitors. New evidence indicates that the expansion of myeloid cell differentiation in pathology is subject to fine-tuning, as its...

Conclusion MTDH is pro-oncogenic factor playing multifaceted and diverse roles in cancer progression. Its association and central role in regulating signaling pathways such a MAPK, wnt/β-catenin, PI3K/AkT, NF-κβ pathways in various cancers shows that it plays a vital role in metastasis. MTDH contribution to chemo and radiotherapy resistance provides a new direction for the development of anticancer therapeutics. Multiple mechanisms converge to promote expression of MTDH in cancers. Further studies are therefore warranted to determine whether the elevated MTDH expression has prognostic value for development...
