Aortic intimal sarcoma with abdominal metastasis: case report and management approach.

Background: Aortic intimal sarcoma is an exceptionally rare malignancy with a poor prognosis. Tumors are predominantly located in the abdominal aorta, thoracic aorta, and thoracoabdominal aorta. Abdominal metastasis of aortic sarcoma is rarely documented, and effective treatment regimens are lacking.

Overexpression of Karyopherin α2 in small cell carcinoma of the cervix correlates with poor prognosis.

Background: Cervical small cell carcinoma (SCCC) is uncommon and little is known about its molecular markers. Karyopherin α2 (KPNA2) has been demonstrated in a variety of malignancies. Our objective was to determine whether the KPNA2 level is predictive of clinical outcome in patients with SCCC.

Patient with EGFR-mutant lung cancer harboring de novo MET amplification successfully treated with gefitinib combined with crizotinib.

While 50% of lung adenocarcinoma patients in Asia have mutations in the epidermal growth factor receptor (EGFR) site, there are few patients with the EGFR mutation accompanied by de novo mesenchymal-epithelial transition (MET) amplification. Due to the low incidence rate, there is no consensus regarding treatment. Here, a case of a 62-year-old never smoker presented with EGFR Exon19del and de novo MET amplification.

Role of Long Noncoding RNA 799 in the Metastasis of Cervical Cancer through Upregulation of TBL1XR1 Expression.

Long noncoding RNAs (lncRNAs) are closely associated with the molecular mechanisms underlying cancer development, and it would be highly useful to study their expression and mechanisms in cervical cancer too. The current study investigated lncRNA799 expression in cervical cancer in order to determine its clinical importance in the progression of cervical cancer. lncRNA799 expression was studied in 218 cervical cancer samples.
