Abstract
Background. A promising experimental approach to the personalized selection of treatment regimens is the study of the sensitivity of tumor cells to drugs in vitro on tumor organoids.Aim. To generate a culture of prostate tumor organoids and to assess the effectiveness of the chemotherapeutic drug docetaxel used to treat prostate cancer on this culture.Materials and methods. The initial tissue was dissociated using gentleMACS Octo homogenizer. Next, the cells were cultured in matrix Matrigel with addition of a serum-free complete nutrient medium. For histological analysis, organoids were fixed in a 10 % formalin solution, followed by staining with hematoxylin and eosin according to the standard protocol. Cell viability was assessed using MTS assay.Results. In this work, we generated a new culture of prostate cancer cells. The histological analysis confirmed that the resulting organoids consist of tumor epithelial cells. As a result of the cytotoxic test, it was shown that in this case docetaxel (82.9 %; p = 0.32) didn’t reduce statistically significantly the viability of prostate cancer cells compared to the control.Conclusion. The use of tumor organoids of prostate cancer for selection of an optimal treatment regimen is a promising experimental technology, however, further research is necessary for its introduction into practice.
