Prognostic value and distribution pattern of tumor infiltrating lymphocytes and their subsets in distant metastases of advanced breast cancer.

Background: There are significant correlations between the levels of tumor infiltrating lymphocytes (TILs) and the prognosis of primary breast cancer. While little is known about immunological mechanisms in the distant metastasis of advanced breast cancer.

Patients And Methods: A total of 106 patients with advanced metastatic breast cancer were enrolled in this study between 2016 and 2022.

Presence, Subtypes, and Prognostic Significance of Tertiary Lymphoid Structures in Urothelial Carcinoma of the Bladder.

Objective: To evaluate the presence and subtypes of tertiary lymphatic structures (TLSs) in urothelial carcinoma of the bladder (UCB) and to analyze their associated clinicopathological characteristics and prognostic significance.

Methods: The study enrolled 580 patients with surgically treated UCB, including 313 non-muscle invasive bladder cancer (NMIBC) and 267 muscle-invasive bladder cancer (MIBC). The presence and subtypes of TLSs were identified by immunohistochemistry (CD20, CD3, Bcl-6, and CD21).

Gold nanoparticles enhances radiosensitivity in glioma cells by inhibiting TRAF6/NF-κB induced CCL2 expression.

Gliomas are inherently difficult to treat by radiotherapy because glioma cells become radioresistant over time. However, combining radiotherapy with a radiosensitizer could be an effective strategy to mitigate the radioresistance of glioma cells. Gold nanoparticles (AuNPs) have emerged as a promising nanomaterial for cancer therapy, but little is known about whether AuNPs and X-ray radiation have cytotoxic synergistic effects against tumors.

Clinicopathological characteristics and prognostic analysis of tumor-infiltrating lymphocytes (TILs) in ductal carcinoma in situ (DCIS) and DCIS with microinvasion (DCIS-Mi) of the breast.

Objective: Our purpose is to evaluate the correlation of TILs with clinicopathological characteristics and disease free survival (DFS) in DCIS and DCIS-Mi breast cancer (BC) patients.

Methods: We retrospectively reviewed the data of 360 DCIS patients and 125 DCIS-Mi patients treated by a single institution from 2016 to 2019. TILs are regarded as continuous variables and are divided into low (≤ 5%), medium (5-40%) and high (≥ 40%) for statistical analysis.

Primary mucinous cystadenocarcinoma of the breast: a clinicopathologic analysis of one case and review of the literature.

Objective: To explore the clinicopathologic features and differential diagnosis of breast primary mucinous cystadenocarcinoma (MCA).

Methods: Pathological characteristics and immunophenotype of one case of MCA were analyzed. Literature was reviewed.

Role of long noncoding RNA-mediated competing endogenous RNA regulatory network in hepatocellular carcinoma.

Long noncoding RNAs (lncRNAs) and microRNAs (miRNAs) are noncoding RNAs (ncRNAs) that occupy over 90% of the human genome, and their main function is to directly or indirectly regulate messenger RNA (mRNA) expression and participate in the tumorigenesis and progression of malignances. In particular, some lncRNAs can interact with miRNAs as competing endogenous RNAs (ceRNAs) to modulate mRNA expression. Accordingly, these RNA molecules are interrelated and coordinate to form a dynamic lncRNA-mediated ceRNA regulatory network.

Effects of human Dachshund homolog 1 on the proliferation, migration, and adhesion of squamous cell carcinoma of the tongue.

Objective: To investigate the expression and role of human Dachshund homolog 1 (DACH1) in the tongue squamous cell carcinoma (TSCC).

Study Design: To explore the expression, regulation, and mechanism of DACH1 in TSCC, nine samples of fresh tumor and adjacent tissues, 51 samples of paraffin-embedded TSCC and paired adjacent tissues, and TSCC cell line SCC-25 were examined. Immunohistochemistry, real-time polymerase chain reaction, Western blot, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, colony formation, Transwell, adhesion assays, and flow cytometry were used.
