AB  - Despite the significant advances in cancer chemotherapy, radiotherapy still remains a method of choice for treatment of metastatic human prostate cancer. This study presents quantitative analysis of 60Co gamma-radiation effects on cell growth and cell death of metastatic human prostate cancer PC-3 cell line, performed in time (24-72h) and dose (2-20 Gy) dependent manner. The irradiated PC-3 cells were mostly dying by necrosis at late time intervals (72h), while apoptotic cell death was negligible. The EC50 or 50% of cytotoxicity was not achieved within the radiation doses used (2-20 Gy), but significant cell growth inhibition with IC50 of 10.4 Gy was observed. It is concluded that the increase in the radiation dose may have an important cytostatic effect, but for the complete eradication of metastatic prostate cancer novel cytotoxic drugs and radiosensitizers should be introduced as adjuvant.
AB  - Uprkos značajnom napretku u hemoterapiji kancera, radioterapija ostaje metod izbora u tretmanu metastaziranog kancera prostate. Ovaj rad predstavlja kvantitativnu analizu efekata 60Co gama zračenja na ćelijski rasti i ćelijsku smrt PC-3 ćelijske linije humanog kancera prostate, pri čemu je praćena vremenska (2-72h) i dozna zavisnost (2-20 Gy). Ozračene PC-3 ćelije su uglavnom umirale nekrozom u kasnijem vremenskom intervalu (72h), dok je apoptoza bila zanemarljiva. Vrednost EC50 odnosno 50% citotoksičnosti nije dostignuta primenjenim dozama, ali je ustanovljena značajna inhibicija ćelijskog rasta, sa vrednošću IC50 od 10.4 Gy. Zaključeno je da povećanje doze može imati značajan citostatički efekat ali da je za kompletno odstranjivanje metastaziranog kancera prostate neophodno uvođenje novih citotoksičnih agenasa ili radiosenzitera kao adjuvanata.

AB  - Background: Prostate cancer is the first as an incidence and the second as a cause of the oncologic mortality in the male population. There is a broad range of possibilities in the prostate cancer therapy. However, there is also much controversy on the most appropriate treatment in the various stages of the disease. Advanced disease is mostly treated by radiation therapy, sometimes in combination with hormone or chemotherapy. Irradiation induces damage of cell biomolecules, which can lead to the arrest in cell division, or to apoptotic or necrotic cell death. The aim of this study was to determine the dose dependence of radiation-induced cell death in two human prostate cancer cell lines, and to define the form of death of these cells. Methods: Human prostate cancer cell lines PC-3 and DU-145 were irradiated with 2 - 30 Gy from 60 Co g-source, at the dose rate of 20 Gy/h. The effect of irradiation on cell viability, morphology and DNA structure were followed 24 - 72 hours after treatment. Cells were analyzed by trypan blue exclusion assay, flow cytometry and DNA gel electrophoresis. Simultaneous staining of cells with Annexin V-FITC and propidium iodide enabled distinction of early apoptosis from late apoptosis and/or necrosis. Results: The results of trypan blue staining indicated that radiation-induced cell death was both time and dose dependent process. According to flow-cytometry and DNA fragmentation assay, necrosis was the prevailing form of the radiation-induced cell death in both PC-3 and DU-145 cells. The apoptosis occurred in insignificant number of cells, probably due to the mutant p53 gene present in both cell lines. The cell necrosis was dose dependent and was most pronounced 72 hours post treatment. Conclusion The prevailing form of radiation-induced PC-3 and DU-145 cell death is necrosis. Both PC-3 and DU-145 are rather radioresistant cell lines, as the dose necessary to induce 50% decrease in viable cell number is about 10 Gy.
