Many papers suggested that laparoscopic treatment of cancer could be achieved and taught safely. Although cases reports about trocar site metastasis and national survey about inadequate management of early ovarian cancer suggested that laparoscopic management of cancer may be dangerous. The current literature may be summarized as follows. An inadequate surgical management performed by laparoscopy as well as by laparotomy may worsen the prognosis of an early ovarian cancer. If the abdominal wall is protected with a bag and the tumour is not morcellated, the incidence of trocar site site metastasis is about 1%. Animal studies demonstrated that the laparoscopic management of cancer has both advantages and disadvantages. Preliminary results from prospective randomised trials in the treatment of colon cancer suggested that the survival rate is similar after laparoscopy and after laparotomy. The risk of dissemination appears high when a large number of malignant cells are present in patients operated using an increased abdominal pressure and a CO2 pneumoperitoneum. These data suggest that laparoscopic treatment of gynaecologic cancer is not dangerous if an adequate surgical technique is used. However morcellation of suspicious solid tumours, treatment of adnexal tumours with external vegetations but without peritoneal dissemination and of bulky lymph nodes should be considered as contra-indications to CO2 laparoscopy, puncture of an ovarian tumour with intracystic vegetations is a high risk situation which should be avoided whenever possible.
