Abstract

Purposes

We focused on the possible benefits of laparoscopic surgery to protect against isolated tumor cells (ITC) generated by surgical manipulation in comparison to open surgery.

Methods

We performed conventional open surgery and laparoscopic surgery for 25 and 8 cases of colorectal cancer (CRC), respectively. We compared the presence of ITC in the peripheral blood (PB) immediately after surgery via quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) for a representative epithelial marker, carcinoembryonic antigen (CEA).

Results

In the 25 patients who underwent open surgery, 8 of the 10 cases with metastasis were positive for ITC in PB, while 13 of the 15 cases without metastasis were negative for ITC. Therefore, we validated that there was a significant clinical usefulness for the detection of ITC in the prediction of metastasis (p = 0.0024). We limited our subsequent analysis to the CRC cases with a Dukes stage of B or C to avoid differences due to the background, and we found that the positive ITC rate for metastasis was higher in the 19 patients who underwent open surgery (42.1 %) than in the 8 who underwent laparoscopic surgery (37.5 %).

Conclusions

The short observation period, especially in the laparoscopic surgery group, and the inadequate number of cases limit the ability to draw any definitive conclusions; however, laparoscopic surgery appears to minimize the surgical manipulation, thus leading to reduced ITC from primary CRC compared with open surgery.
