Minimally Invasive Surgery After Neoadjuvant Chemotherapy for the Treatment of Stage IIIC-IV Ovarian, Primary Peritoneal, or Fallopian Tube Cancer, LANCE Trial

This phase III trial compares minimally invasive surgery (MIS) to laparotomy in treating patients with stage IIIC-IV ovarian, primary peritoneal, or fallopian tube cancer who are receiving chemotherapy before and after surgery (neoadjuvant chemotherapy). MIS is a surgical procedure that uses small incision(s) and is intended to produce minimal blood loss and pain for the patient. Laparotomy is a surgical procedure which allows the doctors to remove some or all of the tumor and check if the disease has spread to other organs in the body. MIS may work the same or better than standard laparotomy after chemotherapy in prolonging the return of the disease and/or improving quality of life after surgery.
