Objective |
We sought to investigate clinical factors affecting accuracy of dilation and curettage (D&C) and frozen section diagnosis of endometrial cancer.
Study Design |
Clinical parameters affecting concordance of D&C or frozen section compared with final hysterectomy pathology were analyzed in 218 patients with endometrial cancer.
Results |
The overall concordance of grade between D&C and final hysterectomy findings was 35.2% (62/176). The following factors increased accuracy of D&C: depth of uterus cavity ≥ 9 cm (P = .043), deep (> 50%) myometrial invasion (P = .03), P53 positivity (P = .023), grade 2 (P = .01), and grade 3 (P = .048). When comparing frozen section with final hysterectomy findings, the concordance was 69% (58/84) in tumor grade and 87% (67/77) in myometrial invasion. Postmenopausal bleeding (P = .004) and less resistance index of endometrial lesion blood flow (P = .005) increased efficacy of grade diagnosis by frozen section.
Conclusion |
Discordance with hysterectomy assessment was most common for women with D&C or frozen section diagnoses of low-grade superficial cancers.
