The modern management of endometrial cancer

Does the Type of Surgical Approach and the Use of Uterine Manipulators Influence the Disease-Free Survival and Recurrence Rates in Early-Stage Endometrial Cancer?

OBJECTIVE

The purpose of this study was to compare the long-term safety, disease-free survival, and recurrence rate of total laparoscopic hysterectomy using uterine manipulator and abdominal hysterectomy in the surgical treatment in early-stage endometrial cancer.

STUDY DESIGN

This was a cohort study of 147 patients with clinical endometrial cancer (laparoscopic surgery group, 77 women; laparotomy group, 70 women). Data were evaluated and analyzed by intention-to-treat principle, and survival data of stage I endometrial cancer (129 patients; 66 from laparoscopic surgery group and 60 from laparotomy group) were estimated by using the Kaplan-Meier curves.

RESULTS

After a follow-up period of 60 months for both laparoscopic surgery and laparotomy groups, no significant difference in the cumulative recurrence rates (7.4% and 13.1%, P = 0.091) and overall survival (97.1% and 95.1%, P = 0.592) was detected between both groups of stage I endometrial cancer. Conversion to laparotomy occurred in 10.4% (8/77) of the laparoscopic procedures. Laparoscopic hysterectomy was associated with less use of pain medication (P = 0.001) and a shorter hospital stay (P < 0.001), but the procedure took longer than laparotomic hysterectomy (P < 0.001). The proportion of patients with intraoperative and long-term complications was not significantly different between both groups. The use of uterine manipulators did not have increased recurrence rate in patients treated with laparoscopic approach.

CONCLUSIONS

The laparoscopic surgery approach to early-stage endometrial cancer using uterine manipulators is as safe and effective as the laparotomic approach.

Understanding the impact of the treatment pathway upon the health-related quality of life of women with newly diagnosed endometrial cancer - a qualitative study

PURPOSE

(1) To determine the impact of treatment and recovery on the health-related quality of life (HRQoL) of endometrial cancer (EC) patients. (2) To explore how treatment types and delivery affect HRQoL and invite suggestions for improvement.

METHODS

Qualitative study. In-depth, semi-structured interviews at 3, 6, 9 or 12 months post-treatment were carried out with 22 women with stage IA to IVB EC who had undergone treatment at a tertiary referral centre for gynaecological cancers in Sheffield, UK. 21 were treated surgically and 4 received adjuvant treatment. Data were analysed using an inductive thematic approach.

RESULTS

Four dominant themes emerged regarding the treatment pathway: pre-treatment concerns, experience during treatment, post-treatment and survivorship issues. Expectations and understandings of EC and its treatment were often inaccurate. Proper explanations eased anxiety but were uncommon. Laparoscopic surgery was welcomed where offered but did not necessarily influence coping ability. Instead, women evaluated treatment impacts against their expectations. Treatments affected women's physical abilities, self-perception and relationships resulting in re-evaluation of lifestyle.

CONCLUSIONS

The impact of treatment upon HRQoL for women with EC differs from other gynaecological cancers. Better information provision would enhance coping ability. Coping methods and expectations appear to influence HRQoL more than treatment modality.

Laparoscopic treatment of endometrial cancer: systematic review

The objective of this review was to assess the efficacy and safety of laparoscopy compared with laparotomy for treatment of endometrial cancer. Trials were identified by searching the Cochrane Gynecological Cancer Collaborative Review Group Trial Register, MEDLINE, EMBASE, PubMed, BIOSIS Previews, the China Biological Medicine Database, China National Knowledge Infrastructure Whole Article Database, Wan Fang Data, and VIP Information, from January 1991 to May 2012, as well as the Cochrane Central Register of Controlled Trials (Cochrane Library, issue 5, 2012). We also hand searched unpublished and gray literature, reference lists of identified studies, gynecologic cancer handbooks, and conference abstracts. All randomized controlled trials (RCTs) comparing laparoscopic surgery with laparotomy for treatment of all stages of endometrial cancer were selected. Data extraction was performed independently by 2 review authors who assessed study quality and extracted data. The whole articles were assessed for method quality by using the Cochrane Collaboration Back Review Group method quality criteria. Heterogeneity between studies was assessed using the I2 statistic, which estimates the percentage of heterogeneity between trials. The outcomes were pooled statistically when no clinical heterogeneity was apparent. For time to event data, hazard ratios were pooled using the generic inverse variance facility of RevMan 5. Random effects models were used for all meta-analyses. The search yielded 9 eligible RCTs (1361 laparotomy and 2255 laparoscopy). There was no significant difference between laparoscopic and laparotomic approaches to endometrial cancer in 3-year overall survival (odds ratio [OR], 0.91; 95% confidence interval [CI], 0.49 to 1.71; p = .77), 3-year disease-free survival (OR, 0.95; 95% CI, 0.29 to 1.80; p = .89), recurrence at 3-year follow-up (OR, 1.11; 95% CI, 0.60 to 2.06; p = .74), and pelvic node yield (mean difference [MD, 0.45; 95% CI, -0.41 to 1.32; p = .30). The benefits of laparoscopic surgery vs laparotomy were shorter length of hospital stay (MD, -3.42; 95% CI, -3.81 to -3.03; p < .01), and lower rates of postoperative complications (OR, 0.62; 95% CI, 0.52 to 0.73; p < .01). Disadvantages were higher rates of intraoperative complications (OR, 1.35; 95% CI, 1.05 to1.74; p = .02) and longer duration of surgical procedures (MD, 32.73; 95% CI, 16.34 to 49.13; p < .01). We conclude that, compared with laparotomy, laparoscopic surgery seems to be beneficial in women with endometrial cancer, in particular insofar as postoperative complications and length of hospital stay. However, more well-designed RCTs are needed to assess the long-term clinical outcomes, in particular the quality of life.

Surgical treatment of endometrial cancer and atypical hyperplasia: a trend shift from laparotomy to laparoscopy

Background. Laparoscopic hysterectomy has proved to be a safe alternative to open surgery in women with benign indications. Few studies compare laparotomy and laparoscopy in gynecologic oncology, and the objective of this study was to analyze the feasibility and development of laparoscopic surgery in endometrial cancer patients. Material and Methods. Records from all women having a hysterectomy due to premalignant or malignant endometrial changes during the years 2002–2009 were examined retrospectively. Results. A total of 521 hysterectomies were performed during the study period. Laparoscopy was performed in about 20% of the cases in the first two years, increasing to 83% in the last year of the period. Moreover, the laparoscopic technique was increasingly applied in older women, more obese women and in women with high-risk preoperative diagnosis, without increasing the complication rate. Conclusions. As for benign indications, laparoscopic hysterectomy in endometrial cancer patients should be preferred whenever possible.
