The median follow-up for all participants was 4.8 years. Overall survival and progression free survival were similar in both arms of the study, but a statistically significant reduction in complications, including postoperative deaths (2.7 percent in PDS versus .6 percent in IDS) was observed. The PDS arm of the study demonstrated a higher rate of hemorrhage (7 percent versus 1 percent) and blood clots (2.4 percent versus .3 percent).
"It was concluded that in patients with very extensive disease, as included in our study, neoadjuvant chemotherapy followed by interval debulking surgery can be considered as the preferred treatment. However, chemotherapy before surgery should not be used in patients with less than FIGO stage IIIc ovarian cancer, or small IIIc ovarian cancers, as these patients were not well-represented in the study" said Prof. Vergote. "Aggressive debulking surgery to no residual tumor remains the most important prognostic factor, underscoring the importance of a maximal surgical effort whenever the surgery is performed, whether the surgery is performed before or after chemotherapy."
Worldwide, nearly 200,000 women are diagnosed of ovarian cancer each year and every year, over 100,000 women die of the disease.
