[Current Studies and Evidence in Cholangiocarcinoma]. / Aktuelle Studien und Evidenz zum Cholangiokarzinom.

Cholangiocarcinoma (CCA) is the second most common type of primary liver cancer and includes a group of intra- and extrahepatic bile tract cancers. Prognosis of patients with CCA remains poor due to high recurrence rates after curative resections and often late diagnosis in advanced stages of the disease. Curative therapy is a complete resection that requires complex surgical procedures and potentially pre-operative induction of liver hypertrophy to ensure sufficient postoperative liver function. Adjuvant therapy with capecitabine for 6 months is well established in clinical routine. The therapeutic landscape for advanced stages is constantly progressing, due to new results of clinical phase II/III trials. On the one hand, molecular analyses have paved the way to effective targeted therapies for subgroups of CCA patients with alterations in FGFR2- or IDH1-signaling. On the other hand, immune-oncological approaches in combination with chemotherapy have resulted in safe and effective treatments for unselected patient cohorts. Further studies will investigate molecular-driven as well as immune-combination treatments in earlier stages of the disease and will result in new therapy options and better prognosis for CCA patients in the near future.

Subtypes of Triple-negative Breast Cancer Cell Lines React Differently to Eribulin Mesylate.

BACKGROUND/AIM: Diagnosis of triple-negative breast cancer (TNBC) is associated with adverse prognosis, particularly in cases of chemotherapy resistance. The goal of this analysis was to compare TNBC vs. non-TNBC cell lines and those of distinct TNBC subtypes with regard to sensitivity to eribulin in vitro. MATERIALS AND METHODS: Breast cancer cell lines were subjected to cell-viability assays, apoptosis analyses, migration and invasion experiments, and quantitative real-time polymerase chain reaction after exposure to eribulin. RESULTS: Eribulin reduced cell viability in TNBC and non-TNBC cell lines in the sub-nanomolar range. Furthermore, exposure to eribulin induced apoptosis and decreased the rate of migration and invasion. Genes known to induce malignant transformation were differentially expressed after eribulin treatment. CONCLUSION: Eribulin had a strong antiproliferative effect on breast cancer cell lines, although we did not observe a significant difference between TNBC and non-TNBC cell lines with regard to sensitivity to eribulin.
