This study retrospectively analyzed the clinical significance of the expression of CCL22 and FOXP3 in 230 cervical cancer patients. Immunohistochemical staining analyses of CCL22 and FOXP3 were performed with a tissue microarray. Double immunofluorescence staining, cell coculture, and ELISA were used to determine CCL22 expressing cells and mechanisms. The higher number of infiltrating CCL22+ cells (CCL22high) group was associated with lymph node metastasis (p = 0.004), Fédération Internationale de Gynécologie et d'Obstétrique (FIGO) stages (p = 0.010), therapeutic strategies...

Hepatoid adenocarcinoma of lung (HAL) is a rare and aggressive tumor. The current study reported a new HAL case in the right lower lung with high serum α-fetoprotein (AFP) level in a 71-year-old male patient. After the confirmation of morphology and immunohistochemistry, the patient was diagnosed clinically with HAL and treated with radio-frequency ablation. However, the patient whose disease progressed eventually died 4 months after diagnosis. Whole genome sequencing analysis identified a driver gene mutation in the FAT atypical cadherin 1 gene (FAT1) and the copy number loss. The tumor was microsatellite-stable and...

Colorectal cancer (CRC) is the third most commonly diagnosed cancer. This review gives an overview of the current knowledge of molecular mechanisms of colorectal carcinogenesis and the role of molecular testing in the management of CRC. The majority of CRCs arise from precursor lesions such as adenoma, transforming to adenocarcinoma. Three molecular carcinogenesis pathways have been identified; (1) chromosomal instability, (2) microsatellite instability (MSI), and (3) CpG island methylator phenotype, each account for ~85%, 15%, and 17%, respectively. Evaluation of MSI status, extended RAS mutation analysis, and BRAF mutati...

Conclusions: These studies suggest that in addition to its role as a palliative therapeutic modality, RFA may have clinical potential as an immune-adjuvant therapy by augmenting the efficacy of adoptive T cell therapy. PMID: 31795828 [PubMed - in process]

Authors: Fu C, Zhou N, Zhao Y, Duan J, Xu H, Wang Y Abstract Increasing evidence supports the concept that cancer stem cells (CSCs) are responsible for cancer progression and metastasis, therapy resistance and relapse. In addition to conventional therapies for colon cancer, the development of immunotherapies targeting cancer stem cells appears to be a promising strategy to suppress tumor recurrence and metastasis. In the present study, dendritic cells (DCs) were pulsed with whole-tumor cell lysates or total RNA of CD44+ colon cancer stem cells (CCSCs) isolated from mouse colon adenocarcinoma CT-26 cell cultures and...

Purpose of review The mutational landscape in lung adenocarcinoma (LADC) is broadly recognized, particularly regarding the presence of the epidermal growth factor receptor (EGFR) mutation in non-smokers. However, even in the EGFR canonical-mutant LADC, other accompanying alterations surface which may have a major impact in prognosis and open possibilities to explore new therapeutic approaches. Recent findings Complex genomic rearrangements, including chromothripsis and chromoplexy, are the origin of most-known fusion oncogenes, including echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase, Clus...

In this study, we investigated genetic variations in EGFR and their association with the clinical and pathological factors of NSCLC. MATERIAL AND METHODS Clinical cases (331 patients) and The Cancer Genome Atlas (TCGA) cases (1040 patients) were selected and analyzed using the refractory mutation systems cBioPortal and the Tumor Immune Estimation Resource (TIMER). RESULTS EGFR mutation frequencies were 54.4% (180 of 331 patients) and 8.0% (83 of 1040 patients) in the clinical and TCGA cohorts, respectively. EGFR mutations were strongly associated with smoking and pathology (P≤0.05) in the clinical cohort, and with gende...

We present a case of a 46 year-old female with advanced cervical adenocarcinoma and metastatic recurrence in the lungs found to have HER2 mutation who underwent first and second-line HER2-targeted therapy with sustained disease response. We review the standard of care for advanced cervical cancer, toxicity profiles of chemotherapy and immunotherapy that were employed, the economics of NGS and targeted treatment, and future directions for HER2-targeted therapy. This case report highlights a patient with metastatic cervical cancer responsive to first and second-line HER2-targeted therapy.
