Registration Number
NCT02986568
Lead Sponsor

Brief Summary

The purpose of this study is to compare standard treatment and fusion ontogenetic surgery (total mesometrial resection, laterally extended endopelvic resection, peritoneal mesometrial resection) for gynecologic cancer in order to evaluate treatment response, adverse effect and survival.

Detailed Description

Fujii method and ontogenetic surgery are the surgical method of radical hysterectomy that can preserve pelvic organ function as much as possible.

Fujii method has advantage of preserving pelvic autonomic nerve with radical resection of tissue under parametrium. And ontogenetic surgery has advantage of reducing need of radiation therapy by radical resection of tissue above parametrium.

This study is prospective study for fusion ontogenetic surgery that has the advantage of both Fujji method and ontogenetic surgery.

Primary Outcome Measures
NameTimeMethod
Treatment-free intervalFrom date of treatment end until the date of first documented progression or date of death (by any cause, in the absence of disease progression) whichever came first, assessed up to 60 months

The time interval from treatment end date to disease recurrence or progression date

Overall survivalFrom the date of treatment start until death due to any cause, assessed up to 60 months

the time interval from treatment start date to death or end of study date

Treatment-related survivalthe time interval from treatment start date to death or end of study date assessed up to 60 months

the time interval from treatment start date to death or end of study date (recurrent or refractory disease)

Progression-free survivalFrom date of treatment start until the date of first documented progression or date of death (by any cause, in the absence of disease progression) whichever came first, assessed up to 60 months

The time interval from treatment start date to disease recurrence or progression date

Secondary Outcome Measures
NameTimeMethod
Postoperative complications 231 days after the ontogenetic surgery through study completion, an average of 1 year

Incidence of late complications, and severity of complications based on Memorial Sloan Kettering Cancer Center Surgical Secondary Events Grading System

Tumor response3 weeks after completion of ontogenetic surgery up to 6 weeks

Tumor response after surgery, and the evaluation is based on revised RECIST version 1.1

Time to normal bladder functionThe time from the ontogentic surgery to the time of confirmation or normal bladder function, assessed up to 60 months

In case of bladder preservation, normal bladder function is evaluated by residual urine check after time voiding, and the volume of residual urine is less than 100cc.

The time from the ontogentic surgery to the time of confirmation or normal bladder function.

Neurologic disturbance of low extremityafter the ontogenetic surgery, up to 30 days

Incidence of motor and sensory disturbances of low extremities, and the grading is based on Common Terminology Criteria for Adverse Events (CTCAE) v5.0

Pain evaluation1 day before the ontogenetic surgery, and at the time of discharge after postoperative management of the ontogenetic surgery assessed up to 60 months

Pelvic pain evaluated by numeric rating scale and morphine milligram equivalents (MME)

Postoperative complications 1after the ontogenetic surgery, up to 30 days

Incidence of early complications, and severity of complications based on Memorial Sloan Kettering Cancer Center Surgical Secondary Events Grading System
