Low-grade serous ovarian cancer is associated with improved survival compared with high-grade serous ovarian cancer, a recent study found. The retrospective study included patients diagnosed with grade 1 or 3, advanced-stage serous ovarian cancer between 2003 and 2011. Researchers found:
- 16,854 patients with high-grade serous ovarian cancer and 755 patients with low-grade serous ovarian cancer were identified.
- Median overall survival was 40.7 months among high-grade patients and 90.0 months among women with low-grade tumors.
- Lymphadenectomy, but not adjuvant chemotherapy, was associated with improved survival in those with advanced-stage low-grade serous ovarian cancer.
