1 Laparoscopy versus laparotomy in the treatment of patients with early stage endometrial cancer
Claudia B.M. Bijen Department of Gynecologic Oncology, University Medical Center Groningen, the Netherlands

2 Endometrial carcinoma
Most common gynecologic malignancy in developing world Peak incidence: year Incidence increases by obesity and age 1400 patients yearly, of which 75% stage I

3 Standard treatment Worldwide: The Netherlands:
TAH + BSO with or without lymphadenectomy, through a vertical midline incision The Netherlands: General gynecologist, TAH + BSO without lymphadenectomy

4 Disadvantages of standard treatment
Highly invasive Visibly scarring Substantial morbidity laparotomy due to frequent obesity and co-morbidity Hospital stay ±1wk Manolitsas 2002, Obermair 2005

5 TLH, a good alternative?

8 Background 1 Potential pro’s of laparoscopy Less post-operative pain
Quicker return to daily activity Shorter hospital stay (2-3 vs 7 days) Less wound complications (2% vs 48%) Higher quality of life Similar recurrence rate Especially feasible for obese and elderly! Eltabbakh 2001,Fram 2002, Manolitsas 2002, Obermair 2003) Obermair 2004)

9 Laparoscopy in the obese
Safe and feasible Similar complication rates Shorter hospitalization Less pain, less wound infections Increased conversion risk Heinberg 2004, Eltabbakh 2000, Obermair 2005, Holub 2000

10 Laparoscopy in the elderly
Shorter hospital stay Less (wound)complications Overall: age not a contraindication for laparoscopy Tozzi 2005, Scribner 2001

11 Background 2 Potential disadvantages of laparoscopy
Longer operation time Longer learning curve Higher per-operative costs (disposables, OR time) More per-operative complications (ureter lesions)

12 Background 3 Laparoscopy seems safe and effective, however…
Only retrospective data Pittfall: patient selection! Also unexperienced gynecologists participated Hysterectomy with lymphadenectomy Not randomised !

13 Pilot study - aim Investigate the feasibility of TLH in patients with early stage EC Evaluate the concept of visiting surgeon and the use of OSATS during the learning curve

14 Pilot Study -design Participating centres: UMCG and 7 northern clinics
TLH procedure instead of abdominal hysterectomy Early stage endometrial carcinoma Benign pathology One (or 2) gynecologist per center Visiting surgeon evaluated learning curve with help of OSATS Before and after pass grade OSATS score Complications per- en postoperative Duration of procedure (min)

15 Pilot Study - major complications

16 Pilot Study - complications
During learning curve N=78 After learning curve N=66 Major complications Complications peroperative Complications postoperative 6 (7,7%) 3 1 (1,5%) 1 Minor complications 9 (11,5 %) 6 6 (9,1%) 2 4 Conversions to laparotomy 7 (9%) 9 (13,6%) Operating time 2:13 ± 0:46* 1:57± 0:30*

17 Pilot Study - complications
During learning curve N=78 After learning curve N=66 Major complications Complications peroperative Complications postoperative 6 (7,7%)# 3 1 (1,5%)# 1 Minor complications 9 (11,5 %) 6 6 (9,1%) 2 4 Conversions to laparotomy 7 (9%) 9 (13,6%) Operating time 2:13 * ± 0:46 1:57 * ± 0:30 # p = 0.08 * P < 0.05

18 Pilot Study -conclusions
Experienced gynaecologists reach the cut off value of 28 points in reasonable time (3-13 x) The use of OSATS to evaluate the competence of the gynaecologists to perform a TLH seems feasible

19 Golden standard…… Randomised Controlled Trial !

20 Randomised controlled trial TLH study
Only RCT can answer the question, which procedure is the best for the patient No randomised data about laparoscopy (without lymphadenectomy) in patients with early stage endometrial cancer No cost-effectiveness data available Complication rate is low with experienced gynecologists ↓ RCT was assigned January 2007!

21 RCT -design Multi –centre: 20 participating centers
Duration: 3 years (start January 2007) Total number of patients needed: 275

22 RCT – outcome Primary outcome: - major complications
Secundary outcome: - costs effectiveness - minor complications - quality of life

23 RCT -inclusion Endometrioid adenocarcinoma
stage I, grade 1-2 Without cervical involvement (curettage/biopsy) Premalignant lesions (atypical hyperplasia) Uteri not larger than ~12 weeks pregancy Age ≥18 jaar Signed informed consent

24 RCT- exclusion Severe cardiopulmonary disease
Unfavourable histopathology papillary serous carcinoma clear cell adenocarcinoma grade 3 adenocarcinoma sarcoma Earlier pelvic radiotherapy
