Nasopharyngeal metastasis from colorectal cancer: a case report.

Metastases from colorectal cancer can occur either through the lymphatic or by hematogenous spread. The most common metastatic sites are the lung and liver. Nasopharyngeal metastasis from colorectal cancer has never been previously reported in the literature on the internet databases we can found.

Identification of lncRNA as a novel prognostic marker in luminal subtype breast cancer.

Background: Luminal subtype breast cancer accounts for a predominant number of breast cancers. Considering the heterogeneity of the disease, it is urgent to develop novel biomarkers to improve risk stratification and optimize therapy choices. Long non-coding RNA (lncRNA) represents an emerging and understudied class of transcripts that play a significant role in cancer biology.

Co-expression networks revealed potential core lncRNAs in the triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is an aggressive type of breast cancer with unfavorable outcome. It is urgent to explore novel biomarkers and potential therapeutic targets in this malignancy. Increasing knowledge of long noncoding RNAs (lncRNAs) significantly deepens our understanding of cancer biology.

A novel long non-coding RNA FGF14-AS2 is correlated with progression and prognosis in breast cancer.

Breast cancer is diverse in their natural history and in their responsiveness to treatments. It is urgent to generate candidate biomarkers for the stratification of patients and personalization of therapy to avoid overtreatment or inadequate treatment. Long noncoding RNAs (lncRNAs) have been found to be pervasively transcribed in the genome and played critical roles in cancer progression.

Unexpected features of breast cancer subtype.

Background: Gene expression profiling of breast cancers identifies distinct molecular subtypes that affect prognosis. The aim of this study was to determine whether features of tumors especially the risks of lymph node (LN) metastases differ among molecular subtypes.

Methods: Subtypes were classified by immunohistochemical surrogates as luminal A, luminalHer2-, luminalHer2+, TNBC, and HER-2+.

Unexpected esophageal diseases appeared in thyroid resections.

Objective: In order to avoid the misdiagnosis of thyroid diseases, we need to discuss the clinical features and diagnostic methods of cervical esophageal cancer and Zenker's diverticulum.

Methods: The clinical and laboratory data of seven cases were reviewed retrospectively, and in all cases, esophageal-related diseases were misdiagnosed as thyroid diseases preoperatively. Among them, two cases were cervical esophageal cancer metastasized to thyroids but initially, they were misdiagnosed as thyroid cancer.
