Ovarian cancer is a tumor with a high trend of recurrence and this occurrence consistently increases the difficulty of the patient cure and reduces the efficacy of current treatments. The role of surgery in persistent or recurrent ovarian cancer is controversial and the type of surgery can be different according to the different stages and invasion of tumor; it can be a debulking surgery followed by chemotherapy (to eradicate the most part of ovarian cancer, leaving a minimal tumoral residue), an interval surgery (for advanced ovarian cancer stage in previously operated patients, followed by 2 or 3 inductive chemotherapy cycles and subsequently a cytoreductive redo surgery) and a cytoreductive secondary surgery, after optimal primary surgical treatment and minimal tumoral recurrence. In some cases it is possible either to perform a debulking surgery during a primary (after the conclusion of primary treatment) or a salvage or palliative surgery (to improve, after an acceptable time period, clinical symptoms in patients with progressive cancer or resistant to treatments). The aims of surgical therapy, to be performed in a patient with ovarian cancer relapse, are to reduce, as much as possible, the tumour size, to increase the quality of life and to increase the survival time; in this review different surgical techniques to be carried out in each case, selected for disease staging, for tumour cells kinetic and for surgical goals, are discussed.
