Objectives

Narrative objectives1

With recent advances in laparoscopic surgery equipment and techniques, laparoscopic surgery for gynecological malignancies has been actively performed overseas. In Japan, laparoscopic surgery for early-stage uterine cancer was approved in 2014, and laparoscopic surgery for early-stage cervical cancer in 2018, and the range of indications for laparoscopic surgery in the field of gynecology is expanding. In ovarian cancer (including fallopian tube cancer, peritoneal cancer, and borderline malignant ovarian tumors), laparoscopic surgery is less likely to be indicated because of the large tumor size and peritoneal seeding in many cases, but good results have been accumulated mainly overseas for early-stage ovarian cancer. In this study, we performed laparoscopic surgery to cure ovarian cancer (including fallopian tube cancer, peritoneal cancer, and borderline malignant ovarian tumors) in patients who were found to have malignant or borderline malignant tumors after oophorectomy and who required additional surgery, or whose lesions had disappeared or markedly shrunk after preoperative chemotherapy. The results were compared with those of laparoscopic surgery performed at the same time. This will allow us to select cases of ovarian cancer (including fallopian tube cancer, peritoneal cancer, and borderline malignant ovarian tumors), perform laparoscopic surgery, and evaluate its feasibility, safety, and prognosis.
