CO2 pneumoperitoneum effects on proliferation and apoptosis in two different neuroblastoma cell lines

In vitro study demonstrates that CO2 pneumoperitoneum produces divergent effects on neuroblastoma cell lines based on MYCN amplification status: decreased proliferation and increased apoptosis in non-amplified cells versus enhanced proliferation in MYCN-amplified cells. Findings suggest MYCN status may influence tumor response to laparoscopic surgery conditions.
