liver cancer

Array-based copy number analysis of primary intrahepatic cholangiocarcinomas and matched lymph node metastases revealed a tumor cluster with ties to survival.

The German drugmaker plans to advance the NSCLC treatment in parallel with tissue-based and liquid biopsy companion assays that can identify best responders.

With sequence data for more than 118,000 tumors profiled at Foundation Medicine, investigators tracked PDL1 amplification prevalence and possible treatment implications.

The team demonstrated that the approach can yield high sensitivity while maintaining near-perfect specificity, but it must now replicate the early results in a much larger study.

Molecular analysis of metastatic CRC in the liver has identified three molecular subtypes that can be coupled with clinical risk scores to inform patient risk.

The assay correlates shortened telomere lengths in patients of different ages to potential risks for inherited diseases, such as bone marrow failure syndrome and liver cancer.

By switching off tumor suppressor genes in immunocompetent mice, the team saw that liver cancer developed and killed the mice within four to five months.  

Given the high yield of miRNA markers they were able to isolate, the researchers believe the approach could be commercialized for routine cancer testing.
