Does the extension of the type of hysterectomy contribute to the local control of endometrial cancer?

Type and approach of hysterectomy and oncological survival of women with stage II cancer of endometrium: a large retrospective cohort study

Objective

To explore the association between the Type and approach of hysterectomy and oncological survival of women with stage II cancer of the endometrium.

Patients and methods

684 women with stage II endometrial cancer were included. Eligible cases were grouped by type of hysterectomy (simple hysterectomy or radical hysterectomy)and approach of hysterectomy (laparoscopy or laparotomy). The baseline characteristics were compared among groups. The survival outcomes (disease-free survival and overall survival) were calculated and compared among groups, and the underlying confounding factors were adjusted by the Cox proportional hazard regression analysis.

Results

The radical hysterectomy group and the simple hysterectomy group had 217 cases and 467 cases, respectively. Between the groups, the difference in 5-year disease-free survival (87.3% versus 87.9%, HR=0.97, P=0.87) and 5-year overall survival (83.8% versus 83.8%, HR=0.95, P=0.95) was not statistically significant. The laparotomy group and the laparoscopy group had 277 cases and 407 cases, respectively. Between the groups, the difference in 5-year disease-free survival (88.7% versus 87.1%, HR=1.22, P=0.34) and 5-year overall survival (85.5% versus 82.7%, HR=1.00, P=0.99) was not statistically significant.

Conclusion

For long-term oncological survival, radical hysterectomy is not superior to total hysterectomy in stage II endometrial cancer. Also, for stage II cancer of the endometrium, laparoscopic hysterectomy is as oncologically safe as open hysterectomy.

OS and DFS are affected by different diagnostic methods and hysterectomy procedures in endometrial cancer patients: A single-center retrospective study

PURPOSE

We aimed to evaluate whether hysteroscopy increases the risk of intraperitoneal dissemination or worsens the prognosis of endometrial carcinoma (EC) patients and whether radical hysterectomy (RH) improves overall survival (OS) or disease-free survival (DFS) in patients with stage II to III EC and to investigate the effects of different procedures for identifying EC and the effects of different surgical methods on the OS and DFS of endometrial cancer patients.

METHODS

Four hundred sixty-five women with EC were included in this retrospective study. Log-rank tests and Kaplan-Meier analysis were used for the outcome comparisons of the effects of the EC diagnostic method and different hysterectomy procedures. A Cox proportional hazards model was used for univariate regression analysis.

RESULTS

Among the three procedures for diagnosing EC (diagnostic curettage, hysteroscopy, and hysterectomy), the incidences of fallopian tube and ovarian invasion were not significantly different (p = 0.506 and 0.066, respectively). The diagnostic methods for EC had no significant effect on OS (p = 0.577) or DFS (p = 0.294). In addition, type II RH and type III RH did not improve the prognosis of patients with FIGO stage II and III disease (log-rank p = 0.914 and 0.810 for OS; log-rank p = 0.707 and 0.771 for DFS, respectively).

CONCLUSION

Based on the current study evidence, the use of diagnostic hysteroscopy procedures is safe and does not increase the risk of fallopian tube and ovarian invasion of intraperitoneal dissemination or worsen the prognosis of EC patients. Type II and type III RH did not demonstrate a benefit for stage II-III EC patients.

Radical hysterectomy is not associated with a survival benefit for patients with stage II endometrial carcinoma

OBJECTIVE

To evaluate the role of radical hysterectomy in the management of patients with stage II endometrial carcinoma.

MATERIALS

Patients diagnosed between 2004 and 2015, with stage II (based on the revised FIGO staging) endometrial carcinoma who had hysterectomy and regional lymph node surgery were identified in the National Cancer Database. Those who had radical or modified radical (RH), or total hysterectomy (TH) were selected. Overall survival (OS) was assessed with Kaplan-Meier curves and compared with the log-rank test. A Cox model was constructed to evaluate survival after controlling for confounders.

RESULTS

A total of 7552 patients who met the inclusion criteria were identified. Rate of RH was 10.5%. Those who underwent RH had longer hospital stay (median 3 vs 2 days, p < 0.001) and a higher 90-day (1.6% vs 0.8%, p = 0.05) mortality. There was no difference in OS between patients who had RH (n = 712) and SH (n = 5955) (p = 0.62); 5-year survival rates were 77.4% and 76.9%, respectively. After controlling for patient age (<65, ≥65 years), race (white, black, other/unknown), insurance status, presence of comorbidities, tumor size (<5, ≥5 cm, unknown), histology (endometrioid, non-endometrioid), performance of adequate lymphadenectomy, and receipt of adjuvant chemotherapy and radiation therapy, performance of radical hysterectomy was not associated with better survival (HR: 1.01, 95% CI: 0.85, 1.21).

CONCLUSIONS

Radical hysterectomy was not associated with a survival benefit in a cohort of patients with stage II endometrial carcinoma.
