| Abstract: | Objective. Laparoscopically assisted vaginal hysterectomy (LAVH) has evolved into an alternative form of surgical management in the treatment of low-risk endometrial cancer. The purpose of this study was to determine whether low-risk endometrial cancer patients are subject to a higher incidence of positive peritoneal cytology when treated with LAVH compared to total abdominal hysterectomy (TAH). Methods. We retrospectively reviewed the medical records of patients with low-risk endometrial cancer (grade 1-2 endometrioid type with no evidence of extrauterine spread or grade 3 with <50% myometrial invasion (MI), no cervical or adnexal involvement, and negative lymph nodes when sampled) treated at Memorial Sloan-Kettering Cancer Center from January 1993 to September 1999. We compared 131 patients treated with LAVH to 246 controls who underwent TAH. The two groups were compared for known prognostic factors including grade, MI, vascular space involvement, and lower uterine segment extension. Results. The mean age of patients who underwent LAVH (61 years) was similar to that of the controls (62 years). Fourteen (10.3%) of the patients treated with LAVH had positive peritoneal cytology compared to only 7 (2.8%) of the control population. Factors including FIGO grade, myometrial invasion, and preoperative hysteroscopy did not influence the final results. When stratifying for these factors, the odds ratios of having positive peritoneal washings in those patients treated by LAVH were 5.2, 5.2, and 3.7, respectively. Conclusion. Treatment of low-risk endometrial cancer by LAVH is associated with a significantly higher incidence of positive peritoneal cytology. This may be due to the retrograde dissemination of cancer cells into the peritoneal cavity during uterine manipulation. The clinical significance of these findings is yet to be determined. © 2001 Academic Press. |
