Abstract:
Background and purpose:Effective treatment for cervical cancer patients is one of the global strategies to eliminate cervical cancer.By analyzing the metastasis characteristics and survival status of patients with distant metastasis of cervical cancer from a hospital-based cancer registry data,our study provided real-world evidence for better survival of cervical cancer and finally eliminating cervical cancer.Methods:A total of 572 cervical cancer patients who had metastasis cancer at the initial diagnosis or developed distant metastasis during follow-up in Fudan University Shanghai Cancer Center from 2008 to 2017 were included in this study.Medical records review,telephone visits and death registry data linkage were applied in collecting endpoint data.The first follow-up date was the diagnose date of metastasis,and the last follow-up date was November 1,2020.Kaplan-Meier method was applied in evaluating the 1-,3-and 5-year overall survival(OS)rates for overall and site-specific patients.Results:The median follow-up time was 38.93 months,and 348 cases died during the follow-up.72.55%were single site metastasis,and 27.45%were multiple metastases.Among all metastatic sites,the proportion of lung metastasis was the highest,41.26%,15.21%to bone,and 11.54%to liver.After metastasis,the 1-year,3-year and 5-year OS rates were 62.29%(95%CI:62.25-62.33),33.13%(95%CI:33.08-33.18)and 23.42%(95%CI:23.37-23.47),respectively.In single site metastasis,1-year OS was the highest after metastasis to the lung(72.52%).Besides,there was no significant difference among different metastatic sites,both in 3-year and 5-year OS.Conclusion:The most frequent distant metastatic sites of cervical cancer are lung,bone and liver.The survival rate after metastasis is poor.Further research with systematic treatment strategy is required for better survival.
