Objective: To analyze the causes of persistent and recurrent gynecologic malignant tumors treated within 1 year.
Methods: 20,974 cases of gynecologic malignant tumors from 61 hospitals in 24 provinces admitted between 1983-1993 were collected. Out of the total, 1753 cases treated within 1 year with tumor persistence, recurrence or death were retrospectively analysed.
Results: The ovarian carcinoma and vaginal cancer had the highest rates of tumor persistence, recurrence or death. Among the 1587 cases of tumor persistence or recurrence, pathological grading were not performed in 56.52% of the cases. For surgical treatment, inappropriate operation were done in 81.68% (767/939) of the ovarian carcinoma, 64.38% (103/160) of the cervical carcinoma, and 70.08% (89/127) of the endometrial cancer. 55.47% (532/959) of ovarian cancer and 38.31% (59/154) of choriocarcinoma and malignant mole had insufficient chemotherapy. For cervical cancer, 54.90% (235/396) of the cases did not receive enough doses of radiotherapy.
Conclusion: Accurate staging and standardized therapy are important for improving 1 year survival rate in malignant gynecologic tumors.
