Current Primary Outcome Measures  ICMJE
 (submitted: May 12, 2019)
  • Incidence of Treatment-Emergent Adverse Events [Safety] [ Time Frame: 3 months after treatment ]
    Adverse events will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events v4.0
  • Purity and Function of NK cells [ Time Frame: once per three months ]
    The purity and function of NK cells will be measured by flow cytometry.
Original Primary Outcome Measures  ICMJE Same as current
Change History No Changes Posted
Current Secondary Outcome Measures  ICMJE
 (submitted: May 12, 2019)
  • Endocrine hormone levels [ Time Frame: every three months, up to 36 months ]
    The levels of endocrine hormone, including serum estradiol, testosterone, progesterone, luteinizing hormone and follicle stimulating hormone will be measured.
  • Pain score [ Time Frame: every three months, up to 36 months ]
    A score of 0 means that you have never had this problem, and a score of 100 means that you are always troubled by this problem and feel unbearable. You can choose any number between 0 and 100 to represent your feelings. The higher the score, the worse your feelings will be.
  • The percent of pregnancy [ Time Frame: 36 months ]
    The pregnancy will be meaured by B ultrasound.

Descriptive Information
Brief Title  ICMJE Clinical Study of NK Cells in the Treatment of Severe Endometriosis
Official Title  ICMJE Clinical Study on the Treatment of Endometriosis by Combining With the Pathogenesis of Endometriosis and the Application Characteristics of NK Cells
Brief Summary Dysfunction of natural koller cells (NK cells) is an important factor in the development of endometriosis. NK cell therapy was applied to treat severe endometriosis, which is an exploration of the pathogenesis of this refractory disease.
Detailed Description Endometriosis (EMs) is one of the common and frequently occurring diseases in women of childbearing age, which seriously affects the health and quality of life of the vast majority of women. The pathogenesis of endometriosis is unknown until now, and the recurrence rate of existing treatment methods is high. It is more and more necessary to introduce new therapeutic methods and strategies in view of the mechanism associated with the reduction of natural killer cell (NK) cytotoxicity. In this study, routine therapy combined with NK cell therapy was used in the treatment of severe endometriosis. The clinical data were collected to confirm the efficacy and safety of NK cell therapy. It is expected to provide a new way of thinking and method for the clinical treatment of EMs.
