Despite significant efforts to improve treatment strategies, the prognosis of patients with ovarian cancer remains poor. Different diagnostic period and the occurrence of distant metastases may have different impacts on prognosis. In this study, we sought to describe the impact of distant metastases and different diagnostic period on prognosis of ovarian cancer. Methods: The Surveillance, Epidemiology, and End Results (SEER) database was used to identify patients diagnosed with ovarian cancer from year 1973 to year 2015. Kaplan-Meier method was used to estimate the overall survival (OS) and Log-Rank test was used to compare the difference between groups. Results: Total 152729 patients with ovarian cancer were included. Median age was 62 years. The overall rates of distant lymph node metastases, bone, brain, liver and lung were 2.9%, 1.0%, 0.2%, 6.6% and 5.6%. Median overall survival (OS) was 30 months, 6 months, 9 months, 20 months and 20 months for pure distant lymph node metastases, brain metastases, bone metastases, lung metastases and liver metastases, respectively. Patients who were diagnosed from year 2010 to year 2015 had significantly improved OS compared with patients who were diagnosed from year 1973 to year 2009 (54 months vs. 47 months, P < 0.0001). Patients with pure distant lymph node metastases who were diagnosed from year 2010 to year 2015 also had significantly improved OS compared with patients who were diagnosed from year 1973 to year 2009 (30 months vs. 24 months, P = 0.0002). In addition, we also observed a trend of longer OS in patients with bone metastases diagnosed from year 2014 to year 2015 compared with patients who were diagnosed year 2010 to year 2013 (10 months vs. 7 months, P = 0.05). Conclusions: The results of this analysis indicated an improved prognosis in patients with ovarian cancer from 2010 to 2014, especially for patients with distant lymph node metastases. In addition, novel treatment strategies are needed for patients with distant visceral metastases.
