Background: There is accumulating evidence on the inhibitory effect of local anesthetic agents on metastasis and tumor recurrence on various cancer types. In this study, we aimed to test the effects of lidocaine, bupivicaine and prilocaine on cellular viability and apoptosis on human endometrial adenocarcinoma cell lines (Ishikawa cells).

Material and methods: Human Endometrial adenocarcinoma cells (Ishikawa cells) were exposed to different concentrations of local anesthetic agents for 24, 48, and 72 hours. The cell viability assay was performed via MTT and concentrations corresponding to 50% effective concentration (EC50) of cells were determined for each agent. Apoptosis was evaluated via commercial Biocolor ApoPercentage assay.

Results: All of the three local anesthetics reduced the amount of viable tumor cells in a dose-dependent manner. The EC50 values (mM) at 24, 48 and 72 h incubation periods were 11.67, 1.915, 2.114 for lidocaine 11.4, 5.21, 3.12 for bupivacaine 7.64 mM, 7.3 mM, and 2.83 mM, for prilocaine respectively.

Conclusion: Lidocaine, bupivacaine, and prilocaine have anti-tumoral effects on Ishikawa cell lines. All of the tested agents induced apoptosis and necrosis at high concentrations in a dose dependent-manner.

Key words: lidocaine, bupivacaine, prilocaine, Ishikawa cell lines, local anesthetics, cancer surgery, metastasis
