| Outline of Final Research Achievements |
Growing evidence indicates that perioperative factors, including choice of anesthetic, affect cancer recurrence after surgery although little is known about the effect of anesthetics on cancer cells themselves. Certain anesthetics are known to affect phenotypes of cells derived from cancer. In this study, we used cells established from cancer tissue and the primary culture cells from the cancer tissue-originated spheroid (CTOS) method.
Our results provide evidence that the anesthetics isoflurane and sevoflurane did not exert a pro-tumorigenic effect on human cancer cell lines and spheroid cells by CTOS. We present evidence that the anesthetics did not affect phenotypes of cells derived from cancer, cell signaling pathway involving in tumorigenesis nor gene expression patterns associated with a malignant phenotype.
