This randomized phase III trial is studying laparoscopic surgery to see how well it works compared to standard surgery in treating patients with endometrial cancer or cancer of the uterus. Laparoscopic surgery is a less invasive type of surgery for cancer of the uterus and may have fewer side effects and improve recovery. It is not known whether laparoscopic surgery is more effective than standard surgery in treating endometrial cancer.

Official Title: A Phase III Randomized Clinical Trial of Laparoscopic Pelvic and Para-Aortic Node Sampling With Vaginal Hysterectomy and BSO Versus Open Laparotomy With Pelvic and Para-Aortic Node Sampling and Abdominal Hysterectomy and BSO in Endometrial Adenocarcinoma and Uterine Sarcoma, Clinical Stage I, IIA, Grade I, II, III

Primary Outcome Measures:
  • Duration of disease-free interval [ Time Frame: Up to 5 years ]
    The usual logrank test or a proportional hazards model will be used to assess the equality of the hazard rates between the surgical procedures.

  • Frequency of aborting LAVH in order to perform an TAH/BSO [ Time Frame: Up to 5 years ]
  • Frequency of major surgical complications, graded according to the NCI CTC and classified as either less than grade 2 or grade 2 or worse [ Time Frame: Up to 5 years ]
  • Length of hospitalization following surgery [ Time Frame: From the date of surgery to the date of discharge, assessed up to 5 years ]
    A proportional odds model will be used to estimate the treatment difference while adjusting for potential confounding factors.

  • Self assessed quality of life scores as measured by FACT-G, Physical Function Subscale from the MOS SF-36, Wisconsin Brief Pain Inventory, Fear of Relapse/Recurrence scale, and Personal Appearance scale [ Time Frame: Up to 6 months ]

Enrollment: 2616
Study Start Date: April 1996
Primary Completion Date: March 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm I
Patients undergo vaginal hysterectomy and BSO via laparoscopy.
Procedure: Laparoscopic Surgery
Undergo vaginal hysterectomy and BSO via laparoscopy
Other Names:
  • laparoscopic-assisted resection
  • laparoscopy-assisted surgery
Other: Quality-of-Life Assessment
Ancillary studies
Other Name: Quality of Life Assessment
Active Comparator: Arm II
Patients undergo total abdominal hysterectomy and BSO via conventional laparotomy.
Other: Quality-of-Life Assessment
Ancillary studies
Other Name: Quality of Life Assessment
Procedure: Therapeutic Conventional Surgery
Undergo total abdominal hysterectomy and BSO via conventional laparotomy

Detailed Description:


I. Compare the incidence of surgical complications, peri-operative morbidity, and mortality in patients with stage I or IIa, grade I-III endometrial cancer or uterine cancer undergoing surgical staging through laparoscopic assisted vaginal hysterectomy vs total abdominal hysterectomy.

II. Compare the length of hospital stay after surgery in patients receiving these treatments.

III. Compare the quality of life of patients receiving these treatments. IV. Compare the incidence and location of disease recurrence in patients receiving these treatments.

OUTLINE: This is a randomized, multicenter study. Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients undergo vaginal hysterectomy and bilateral salpingo-oophorectomy (BSO) via laparoscopy.

ARM II: Patients undergo total abdominal hysterectomy and BSO via conventional laparotomy.

Patients in both arms also undergo pelvic and para-aortic lymph node sampling. Quality of life is assessed at baseline, at 1, 3, and 6 weeks, and then at 6 months.

Patients are followed at 6 weeks, every 3 months for 2 years, and then every 6 months for 3 years.
